[PATCH v4] drm/i915: pass ELD to HDMI/DP audio driver

[PATCH v4] drm/i915: pass ELD to HDMI/DP audio driver

[Wu Fengguang]

Add ELD support for Intel Eaglelake, IbexPeak/Ironlake,
SandyBridge/CougarPoint and IvyBridge/PantherPoint chips.

ELD (EDID-Like Data) describes to the HDMI/DP audio driver the audio
capabilities of the plugged monitor. It's built and passed to audio
driver in 2 steps:

(1) at get_modes time, parse EDID and save ELD to drm_connector.eld[]

(2) at mode_set time, write drm_connector.eld[] to the Transcoder's hw
    ELD buffer and set the ELD_valid bit to inform HDMI/DP audio driver

ELD selection policy: it's possible for one encoder to be associated
with multiple connectors (ie. monitors), in which case the first found
ELD will be used. This policy may not be suitable for all users, but
let's start it simple first.

The impact of ELD selection policy: assume there are two monitors, one
supports stereo playback and the other has 8-channel output; cloned
display mode is used, so that the two monitors are associated with the
same internal encoder. If only the stereo playback capability is reported,
the user won't be able to start 8-channel playback; if the 8-channel ELD
is reported, then user space applications may send 8-channel samples
down, however the user may actually be listening to the 2-channel
monitor and not connecting speakers to the 8-channel monitor. Overall,
it's more safe to report maximum profiles to the user space, so that
the user can at least be able to do 8-channel playback if he want to.

This patch is tested OK on G45/HDMI, IbexPeak/HDMI and IvyBridge/HDMI+DP.

Minor imperfection: the GEN6_AUD_CNTL_ST/DIP_Port_Select field always
reads 0 (reserved). Without knowing the port number, I worked it around
by setting the ELD_valid bit for ALL the three ports. It's tested to not
be a problem, because the audio driver will find invalid ELD data and
hence rightfully abort, even when it sees the ELD_valid indicator.

Thanks to Zhenyu and Bossart for a lot of valuable help and testing.

Re: [PATCH v4] drm/i915: pass ELD to HDMI/DP audio driver

[Wu Fengguang]

Keith: this version completes the IvyBridge support :)

Bossart: hotplug is working fine now, with some minor issues:

- on G45, monitor hot removal is not handled at all in
  i915_driver_irq_handler(). I'll leave it as a future TODO.

- on IvyBridge, _repeated_ plug/unplug will trigger

  [ 1183.654859] ALSA hda_eld.c:259 HDMI: Unknown ELD version 0

  which means the ELD_valid flag will be seen by audio driver,
  however it cannot get any valid ELD data. I double checked and
  find everything in the graphics driver is working as expected:
  ironlake_write_eld() is writing the good ELD data to the same
  pipe on hot plug events. So I'll leave it as a possible bug of
  the early stage hardware.

Thanks,
Fengguang

[PATCH v5] drm/i915: pass ELD to HDMI/DP audio driver

[Wu Fengguang]

Changes from v4: remove a debug call to dump_stack().
Thanks to Bossart for catching this!
---

Add ELD support for Intel Eaglelake, IbexPeak/Ironlake,
SandyBridge/CougarPoint and IvyBridge/PantherPoint chips.

ELD (EDID-Like Data) describes to the HDMI/DP audio driver the audio
capabilities of the plugged monitor. It's built and passed to audio
driver in 2 steps:

(1) at get_modes time, parse EDID and save ELD to drm_connector.eld[]

(2) at mode_set time, write drm_connector.eld[] to the Transcoder's hw
    ELD buffer and set the ELD_valid bit to inform HDMI/DP audio driver

ELD selection policy: it's possible for one encoder to be associated
with multiple connectors (ie. monitors), in which case the first found
ELD will be used. This policy may not be suitable for all users, but
let's start it simple first.

The impact of ELD selection policy: assume there are two monitors, one
supports stereo playback and the other has 8-channel output; cloned
display mode is used, so that the two monitors are associated with the
same internal encoder. If only the stereo playback capability is reported,
the user won't be able to start 8-channel playback; if the 8-channel ELD
is reported, then user space applications may send 8-channel samples
down, however the user may actually be listening to the 2-channel
monitor and not connecting speakers to the 8-channel monitor. Overall,
it's more safe to report maximum profiles to the user space, so that
the user can at least be able to do 8-channel playback if he want to.

This patch is tested OK on G45/HDMI, IbexPeak/HDMI and IvyBridge/HDMI+DP.

Minor imperfection: the GEN6_AUD_CNTL_ST/DIP_Port_Select field always
reads 0 (reserved). Without knowing the port number, I worked it around
by setting the ELD_valid bit for ALL the three ports. It's tested to not
be a problem, because the audio driver will find invalid ELD data and
hence rightfully abort, even when it sees the ELD_valid indicator.

Thanks to Zhenyu and Bossart for a lot of valuable help and testing.

Be aware that many TVs will either refuse the display anything or pop-up
an OSD warning whenever they receive hdmi audio which they cannot handle.

Sending 8-channel in your example may render the stereo-only monitor useless.

That said, one step at a time is reasonable.  But eventually you will 
require configurability and/or per-monitor audio control even when the
video is cloned.

What is the correct way to test this patch. Just plug in the HDMI
monitor and it should work out of the box?

This register naming is inconsistent with its intent. If these registers
were indeed introduced on Ironlake as you seem to imply by using them
with Ironlake, you should label them as GEN5 and not GEN6.

This patch should be split between adding the core drm functionality to
build the ELD and the introduction of i915 support.

My first name is Fengguang. "LAST NAME, FIRSTNAME" is the convention

Just plug in the HDMI/DP monitor, and run

        cat /proc/asound/card0/eld*

to check if the monitor name, HDMI/DP type, etc. show up correctly.

The alignments are actually good in the source code.  It's the leading
"+" in the patch file that makes some of the lines "appear" to be
unaligned.

Thanks for the careful review!

OK. I didn't do this because I was not sure if it's OK to just add the
drm_*() functions without any code to call them..

Right, we don't introduce new interfaces without users - but it is
acceptable to say "... which will be used by i915 in a following patch" if
you want to clarify the need for the interface. It just helps to
compartmentalize the damage should we find something goes horribly wrong
later.

Sounds pretty reasonable. And the logical split may help make a bit

Re: [PATCH v5] drm/i915: pass ELD to HDMI/DP audio driver

[Christopher White]

There appears to be some issues with the patch? I'm on SandyBridge and 
using the HD3000's HDMI.

I've now tried manually merging the ELD patch (both files Wu Fengguang 
submitted) and compiling Kernel 3.0.4. I've also tried drm-intel-next 
Kernel 3.1 pre-built from 
http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/current/ as 
I knew it was built from keithp's latest drm-intel-next repository.

Both of these methods had the patch applied, yet neither were able to 
read the ELD correctly from my Onkyo TX-SR607 receiver.

If I manually dump the EDID from my receiver and analyze it with Monitor 
Asset Manager (by EnTech Taiwan), it shows that the ELD contains an 8 
channel specification up to 192 kHz, and that's what's being exposed 
over HDMI to the Intel graphics adapter, yet this isn't detected. It 
just plain isn't being read, and is falling back to the default 2ch 
16kHz configuration. It's exactly as it was in the past, before this 
patch attempt.

You can see my 256 byte EDID dump, straight from the receiver, over at:
http://www.pulseforce.com/node/edid.dump

It shows exactly what the receiver is exposing over HDMI, proving that 
it's not the device that's at fault.

Any ideas what's wrong? Here's the HDMI messages from the startup log:

HDMI status: Pin=7 Presence_Detect=1 ELD_Valid=1
HDMI: detected monitor  at connection type HDMI

HDMI: supports coding type LPCM: channels = 2, rates = 44100 48000

Would you boot the kernel with drm.debug=6 and post the dmesg?
That will show more details.

One possible problem is the hardware reports small ELD buffer size
which truncates the additional 8-channel information.

Done. Sorry for the delay, didn't see your message until now, and also 
had to re-build the kernel.

The log does confirm that the drm_edid_to_eld function is running, and 
that we're not far from a solution:
[   21.061417] [drm:drm_edid_to_eld], ELD monitor TX-SR607
[   21.061421] [drm:drm_edid_to_eld], ELD size 13, SAD count 8

As for where I am getting the EDID dump from, I am getting it from 
/sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-HDMI-A-2/edid, 
which provides direct virtual access to the EDID response of the 
connected device.

I'm completely confident that the device doesn't report too small of a 
buffer size, and that it's completely compliant with the spec: If you 
have a Windows virtual machine (or if you're masochistic enough - a real 
machine) you should download the excellent, free "Monitor Asset Manager" 
by EnTech Taiwan from http://www.entechtaiwan.com/util/moninfo.shtm. It 
will let you analyze EDID + ELD + extended timings, etc from an EDID 
dump, such as the one taken above. It understands every part of EDID.

I've put together a small archive containing my exact EDID binary dump 
(taken from the above device path), the FULL dmesg log, as well as 
EnTech's interpretation of the EDID dump, showing the full list of 
supported channels, formats, etc.

I'm guessing there is some tiny bug in your interpretation of how to 
read ELD, maybe an incorrect 1 byte offset or something like that.

Here's the pack:
http://www.pulseforce.com/node/edid_to_eld.zip

If you do a hex analysis of my EDID dump and compare it to what the 
edid_to_eld function is trying to do, it will probably show what's 
wrong. I'd love to have a look at that myself but am really busy with a 
project over here so I can't help out other than to recompile and test 
as fast as I can.

Would you install the "intel-gpu-tools" package and run its
intel_audio_dump utility? If not shipped with your distribution, the
source code is also available in

git://anongit.freedesktop.org/git/xorg/app/intel-gpu-tools

You'll need to install packages "autotools-dev pkg-config
libpciaccess-dev libdrm-dev libdrm-intel1" in order to build it from
source.

intel_audio_dump will dump the ELD data in the hardware buffer for use
by the audio driver. By verifying if that data is correct, we are able
to analyze whether and how the audio driver goes wrong.

Fengguang

I think I experience similar issues. In my case the multi-channel pcm
playback through HDMI doesn't work. Stereo and passthrough seem to
work fine though !? It's hookedup  to my TV via a yamaha receiver.

I'm currently running Linux 3.1 with a G45 chipset.

libdrm 2.4.27-1
xf86-video-intel 2.16.0-1

The eld seems be incorrectly parsed, though the kernel log didn't give
much info. The eld info from alsa is rather empty:

cat /proc/asound/Intel/eld#3.0
monitor_present		1
eld_valid		0

Using the same Monitor Asset Manager I was able to verify that the edid from
(/sys/devices/pci0000\:00/0000\:00\:02.0/drm/card0/card0-HDMI-A-1/edid
) does seem to contain the correct information.

I've attached both the edid and the output of Monitor Asset Manager.In
addition I also run the intel_audio_dump.

Let me know if you need anymore information.

Cheers,

Sander

do you have Fengguang’s patch applied? This thread is about testing that
patch.

It would be great if you could test the patch.

Yeah, multi-channel playback should not work due to the audio driver
not knowing the HDMI sink is multi-channel capable.

Stereo and passthrough should work always.

In fact Linux 3.1 does not have the ELD patch yet. It should go into
the upcoming 3.2.

That's good.

As the ELD patch is not there, intel_audio_dump correctly reports

        AUD_CNTL_ST ELD valid			0

I'm not sure if it's convenient for you to compile new kernels (with
the ELD patch applied).  If not, we can wait Christopher White for the
feedback.

Ah, that explains. I was under the impression this was already in 3.1
(but then again, it was rather late for me :) )
I will give the patch a try and report back.

I applied the patch you posted on Sept 3 to Linux 3.1. This was just a
quick test, I didn't have more time to look at it in more detail this
morning.

The initial look really good. I've been able to playback multi channel
audio and the speaker-test was also successful. Now I did boot without
the TV on, so it initialized xorg with some weird resolution from the
receiver (one not supported by the TV). From what I remember looking
at the edid returned from the receiver only, I believe it include
timings for 1080p (I'll post this edid later today if needed).

 - For analog multi channel playback, you usually have to select one
of the surround* devices in Alsa since the 'default' device only knows
about stereo and has no idea about channel ordering of the hardware.
I assume since the eld contains this information, the hdmi will also
have a implied pcm channel ordering?

- With the patch, would passthrough of DTS-HD and Dolby True-HD also
work? Although I read somewhere the HBR flag needs to be set in order
to pass this losslessly, though that doesn't seems to be set according
to the audio dump.

Cheers,

Sander

I have a similar receiver to Christopher, an Onkyo TX-SR507, which is the same
model year, but fewer speaker outputs (5.1 instead of his I think 7.2). I had
been having trouble getting ELD data to read properly, but was able to play
sound (for the most part, I'll touch on that below). I have an ECS H55H-I, so
the H55 chipset. The alsa generated file /proc/asound/card0/eld#3.0 used to say
there was no valid ELD data and just had zeroes in all fields.

Following Keith Packard's suggestion, I checked out rev
43672a0784707d795556b1f93925da8b8e797d03 (I forget how much you can truncate a
git rev number and still be safe) from Linus's kernel git.
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git . I compiled
and restarted and then I did get good ELD. There is a peculiar error at the end
of dmesg that says "[73093.946346] [drm:drm_edid_block_valid] *ERROR* EDID
checksum is invalid, remainder is 29", but the proc eld file still looks good.

Despite all of that, speaker-test only gives good results with the rate set to
44100 or its multiples 88200 and 176400. 32000, 48000, 96000, 192000 do play the
pink noise, but drop out intermittently. The problem seems to either cause or be
an effect of the receiver losing its mind about what the incoming stream is.
While it plays the 44100 speaker-test the front panel lights are locked in to
"PCM MULTICHANNEL HDMI". When I play 48000 the same lights come on, but every
few seconds PCM and MULTICHANNEL will go off at the same time, followed by HDMI.
This is when the sound cuts out, the video however remains on screen untouched.
The HDMI light will come back on shortly after, followed by the PCM MULTICHANNEL
and sound will resume. 

This was a problem before the patched kernel that I was hoping proper ELD info
would clear up. I see no messages in dmesg while the skipping is occurring, nor
anything interesting from HDAAnalyzer.

Here are some dumps:

I've been really busy on a project (as mentioned in my last posting) and 
apologize for the 2 day delay. The project is now done and no further 
response delays will happen. Promise.

Alright, so first of all I am glad that you found the tool and 
information useful.

Now, onto the intel-gpu-tools test. I ran intel_audio_dump as requested 
and it only comes back with "Couldn't map MMIO region: No such file or 
directory". I spent 10 minutes looking around on Google to no avail. It 
seems it tries to mmap() something that doesn't exist.

I then spent some time looking in /var/log/Xorg.0.log to double-check 
what driver it's using. It says:
"Matched intel as autoconfigured driver 0
Matched vesa as autoconfigured driver 1
Matched fbdev as autoconfigured driver 2
VESA: driver for VESA chipsets: vesa
FBDEV: driver for framebuffer: fbdev
Loading: /usr/lib/xorg/modules/drivers/intel_drv.so"

All in all it looks fine, at least as far as I can tell. I mean, we 
already KNOW the driver has to be running since I see the DRM module in 
the logs.

So, the Intel driver is running, yet whatever file intel_audio_dump is 
looking for doesn't exist.

We already know that the DRM driver is reading the correct EDID, by the 
way, since we saw "[   21.061417] [drm:drm_edid_to_eld], ELD monitor 
TX-SR607".

The EDID it's reading from is the dump I linked to in the previous posting.

To go the extra mile, I just looked at the xf86-video-intel source in 
src/reg_dumper_util.c, which is where the "Couldn't map MMIO region" 
message originated. I now see that it's not trying to mmap() a physical 
file. It tries to map the graphics card's physical memory using 
pci_device_map_range(dev, dev->regions[mmio_bar].base_addr, 
dev->regions[mmio_bar].size, PCI_DEV_MAP_FLAG_WRITABLE, &mmio);

It tries that AFTER it has already found the graphics adapter and 
verified that it's from Intel.

So, why it fails to actually map the memory of the device is anyone's 
guess. Perhaps there's no support for the HD3000 in intel_audio_dump?

Anyway, with all of this out of the way: Why not instead look at the 
EDID binary dump I sent you and step through the edid_to_eld() function 
to see what it's doing?

Re: [PATCH v5] drm/i915: pass ELD to HDMI/DP audio driver

[Wu Fengguang]

[-- Attachment #1: Type: text/plain, Size: 2574 bytes --]

Hi Christopher,

I don't find anything wrong with the ELD parsing code, however I do
find a bug that prevented ELD from being passed to the audio driver on
SandyBridge.

I just posted the fix. For your convenience, it's attached in this
email too.

Thanks,
Fengguang

Subject: drm/i915: fix ELD writing for SandyBridge
Date: Wed Nov 09 13:17:14 CST 2011

SandyBridge should be using the same register addresses as IvyBridge.

Re: [PATCH v5] drm/i915: pass ELD to HDMI/DP audio driver

[Christopher White]

[-- Attachment #1.1: Type: text/plain, Size: 3697 bytes --]

Good day, Fengguang! Great work! This sounds very promising!

I went through the ELD parsing code myself (drm_edid_to_eld), as my 
programmer mind's curiosity killed me even though I didn't really have 
time for it, and I could see that it grabs the CEA extension block, 
grabs the monitor name string, then goes through each data block 
collection, copying all short descriptor data for each of the block 
types we're interested in. Good and clean code.

So, I came to the same conclusion - that the parsing code was completely 
correct. I'm therefore very happy to hear that you've found the real 
problem; trying to write the ELD structure to the wrong audio registers 
on SandyBridge. Yep, that HAS to be it!

I've applied the patch and the kernel is currently being re-built, but 
I've got to leave home so I won't report back until later today.

However, I am confident that you've found the true cause of the problem. 
Superb work once again!

You're going to make a lot of Home Theater PC owners very happy.

Re: [PATCH v5] drm/i915: pass ELD to HDMI/DP audio driver

[Christopher White]

[-- Attachment #1.1: Type: text/plain, Size: 5117 bytes --]

Couldn't resist connecting to my machine over VNC even though I'm not home.

So, I booted it with the new patch and see that while you HAVE found the 
bug, the new register addresses still seem to be wrong. Instead of the 
audio registers containing their default, pre-filled, standard 2-speaker 
configuration, it's now being overwritten - which is good. With garbage 
- which is bad. ;-) One possible cause is that the SandyBridge addresses 
shouldn't use the same register addresses as IvyBridge after all. This 
will have to be double checked.

Instead of /proc/asound/card0/eld#3.0 containing the default 2-speaker 
configuration, it now contains:
monitor_present        1
eld_valid        1
monitor_name
connection_type        HDMI
eld_version        [0x0] reserved
edid_version        [0x0] no CEA EDID Timing Extension block present
manufacture_id        0x0
product_id        0x0
port_id            0x0
support_hdcp        0
support_ai        0
audio_sync_delay    0
speakers        [0x0]
sad_count        0

You can see that the data is obviously zeroed out, and I bet it's due to 
a misaligned address.

Booting with drm.debug=6 produced the attached log file which I've 
included for completeness. However, there's nothing strange in it.

Yeah, AFAICS the BIOS may choose to pre-fill some simple ELD at boot time.

One step forward ;-)

What puzzled me is that I've been testing DisplayPort on a Sandybridge
notebook today and it is working fine.

The other question is, why the intel_audio_dump tool goes wrong with
your hardware? It's reading the right register addresses in all the
boxes I tested...

So at least it sets the ELD valid bit right.

Did you view *every* ELD file?

        cat /proc/asound/card0/eld*

I verified that it's writing to the right address in the spec. And even
find direct evidence in your dmesg that the ELD contents are correctly
received and interpreted by the audio driver:

What if you run it with

        export HAS_PCH_SPLIT=1
        intel_audio_dump

I also queued a patch for the tool. Note that if the above trick
failed to work, the applied patch won't help, too.

Thanks,
Fengguang

Hi Fengguang, I am quoting both your messages below so read until the

Indeed, I could tell that the 2ch standard configuration was a

I've got good news about that further down.

Hehe. That might be a side effect of incorrect writing though. We'll see.

Yeah, the attached _eld.txt file shows that there is only *one* ELD file 
there. This is the file that used to contain the default 2ch 
initialization of the audio registers. At least we've come far enough 
that it's now being overwritten. It's being incorrectly overwritten or 
corrupted afterwards, but it's a start.

Hmm, wow, I compared this to my older dmesg.log which I gave you a few 
weeks ago, and that's definitely news. It was only showing the default 
2ch configuration before. Now it IS writing to the correct address. How 
VERY strange! So it DOES write to the correct register... It gets 
STRANGER though, as you'll see at the bottom of this email.

The dump tool did not work with that environment variable either. 
However, it occurred to me that intel_audio_dump may be too outdated in 
my distro. It was built on 2010-04-01, v1.0.2+git20100324. If I look at 
http://cgit.freedesktop.org/xorg/app/intel-gpu-tools/ I can see that the 
reason for this is that the latest stable was 1.0.2 tagged nearly two 
years ago.

I decided to build intel-gpu-tools from the latest Git source instead. 
That took a while to figure out as it also needed xutils-dev package for 
xorg-macros.m4, required by the autoconf script, and libtool (needed by 
the resulting configure script). So the complete list of dependencies is 
"autotools-dev pkg-config libpciaccess-dev libdrm-dev libdrm-intel1 
xutils-dev libtool". DebugFS must also be ready and mounted on 
/sys/kernel/debug and enabled in the kernel (kernel hacking > debug file 
system). Finally, building it is standard procedure with autogen.sh, 
configure, make and make install. (I am writing down these instructions 
just in case someone else reads this down the line; Google is a 
wonderful thing).

After building, I tried running intel_audio_dump, and was first 
dumbfounded as it gave me the same error, "Couldn't map MMIO region". I 
verified with "which intel_audio_dump" that it DID point to the NEW 
/usr/local/bin/intel_audio_dump path, and not the OLD 
/usr/bin/intel_audio_dump path.

However, I thought that maybe it WAS running the OLD version for some 
reason despite claiming it was pointing to the new one. So, I tried 
calling it specifically with the full path to the new binary, and... 
SUCCESS! You need to tag a new release version of intel-gpu-tools soon 
so that distros are updated, since the old 1.0.2 release does NOT 
support SandyBridge.

I've attached the full dump here. Scroll down to the bottom and you can 
see that I was right in my theory that all the ELD data was zeroed out. 
But hey at least we're getting SOMEWHERE! ;-)

So what we KNOW now: ELD parsing code = 100% correct. ELD writing to 
correct audio register = 100% correct, verified by looking at 
snd_hdmi_show_eld()'s output in dmesg log. However, SOMETIME after the 
boot, it seems that it gets corrupted/zeroed out. I'll replicate the 
relevant dump portion here:

AUD_HDMIW_HDMIEDID_A HDMI ELD:

00000000

I decided to look in /sys/class/drm/card0-HDMI-A-2/edid and it's 0 
bytes! This used to be 256 bytes! How freaking weird is that?! That 
means: System boots up, Intel driver sees 256 byte EDID, parses it into 
ELD, writes it to the audio register, the system dmesg log shows that it 
parsed all supported audio modes correctly, then the system boots and 
edid becomes 0 bytes, and the ELD is zeroed out. What the heck is going 
on here? :-O I tried "dmesg | grep "HDMI: detected monitor"" and see 
NOTHING later than the initial boot event, meaning I have no freaking 
clue why it's zeroing out the EDID.

It almost looks like the act of writing ELD to the audio register is 
tampering with the ability of the graphics card to read the EDID itself 
after that point. Erhmm... This is very odd.

Finally, I tried a complete power cycle of every component, turning off 
the outlet power on everything. I then started the Receiver, then the 
Projector, and finally the computer. Not that startup order matters 
much, but this is the optimal order. However, it still did the same 
thing. With one difference. /sys/class/drm/card0-HDMI-A-2/edid now 
contains the correct contents. Everything else was as before: 
/proc/asound/card0/eld#3.0 full of zeroes as shown in the attached file. 
Intel_Audio_Dump showing the EXACT SAME zeroed out content as I have 
quoted above. DMESG showing the exact same, nice list of supported 
codecs and rates.

So, somewhere AFTER the write of correct ELD to the audio register, it 
all goes wrong and gets zeroed out. I'm thinking POSSIBLY some routine 
that runs after snd_hdmi_show_eld() could be responsible for clearing 
all data?

This is on an ASUS P8H67-I B3 m-ITX Intel H67 motherboard, and an Intel 
Core i5 2500K CPU with Intel HD3000.

Err... wait a minute! I think I've figured it out!

My Intel H67 motherboard has ONE HDMI output. That port is connected to 
card0-HDMI-A-2 internally (port two, NOT port one).

Now note the audio register dump again:

AUD_HDMIW_HDMIEDID_A HDMI ELD:
     10000d00 6882004f 00000000 00000000 3dcb6508

00000000

It has written Port 2's ELD to Port 1, and zeroed out all other ports. 
So OF COURSE when the driver goes to query the ELD for port 2, it finds 
zeroed out data.

Could this be it!? If so, this would be a bug related to the current 
TODO/FIXME of "needing per-port ELD parsing".

Re: [PATCH v5] drm/i915: pass ELD to HDMI/DP audio driver

[Wu Fengguang]

Christopher,

Did you enabled CONFIG_SND_DEBUG and CONFIG_SND_DEBUG_VERBOSE in
kconfig? I've been looking for the error messages related to zeroed
ELD but never managed to find any in your dmesg.

Some analyzes of your dmesg:

- all drm_edid_to_eld() invocations reads valid EDID data:

No, I was unaware of these options, this is the first time you've 
mentioned them. ;-)

However, I am unable to reproduce the 0-byte EDID again. Even after 
multiple reboots, turning the projector on/off, etc. Hmm. We'll have to 
forget that issue since it's not reproducible anymore. It's always odd 
when code does one thing one time and another thing every other time, 
but hopefully it was just some weird fluke, race condition, 
who-knows-what...

Heck it could even be the TX-SR607 receiver that did something odd this 
one time.

I looked at the latest dmesg after yet another reboot and see only a 
single "[drm:intel_hdmi_mode_set], Enabling HDMI audio on pipe A" event, 
and no misreads. I'll attach that file too just for completeness.

Anyway, we know that it reads ELD correctly and writes it to the audio 
register correctly, as we see from the logs. However, my previous 
message ended in a theory that the problem is that the ELD is written to 
the register for port 1 but my device is on port 2. Re-read the bottom 
of the message I sent previously, and it'll detail the idea. It's a 
possibility worth checking out.

Sorry I should have reminded you of the build dependencies. I use
debian and it's fairly easy for me to install the relevant packages:

apt-get build-dep intel-gpu-tools

Yes, and I'm still puzzled how come ironlake_write_eld() writes
nonzero ELD to pipe A and the audio driver gets all zero. Some hw
reset in between (sounds very unlikely)?

That's written by ironlake_write_eld(), which will never write all
zeros because it has an explicit test

        if (!eld[0])
                return;

I'm sure that the gfx/audio driver code I wrote won't zero out the
ELD SILENTLY without any clues in dmesg. There must be something else
happening.

The user space is also able to zero out the ELD by writing to
/proc/asound/card0/eld#3.0, however this is also very unlikely to
happen.

Nope. ironlake_write_eld() never writes zero ELD to hardware.

It cannot explain why ironlake_write_eld() always write to pipe A and
the audio driver sometimes gets the right ELD and sometimes get zero.

OK. We still have the time :-) Enable CONFIG_SND_DEBUG and use it for
months. If it occurs again, we at least have more error messages.
Otherwise it at least demonstrates itself to be some less disturbing

The theory still cannot explain it well.. see the direct reply to the
email. For now let's treat it as some hardware mysteriousness...

Re: [PATCH v5] drm/i915: pass ELD to HDMI/DP audio driver

[Wu Fengguang]

Wow I reproduced the bug and got a very interesting dmesg:

gfx =>        [ 4561.287980] [drm:intel_write_eld], ELD on [CONNECTOR:12:HDMI-A-2], [ENCODER:11:TMDS-11]
gfx =>        [ 4561.291730] [drm:ironlake_write_eld], ELD on pipe B
gfx =>        [ 4561.293804] [drm:ironlake_write_eld], Audio directed to unknown port
gfx =>        [ 4561.295273] [drm:ironlake_write_eld],
      alsa => [ 4561.295486] HDMI hot plug event: Codec=3 Pin=6 Presence_Detect=1 ELD_Valid=0
      alsa => [ 4561.295564] HDMI status: Codec=3 Pin=6 Presence_Detect=1 ELD_Valid=0
gfx =>        [ 4561.300020] ELD size 13
      alsa => [ 4561.300697] HDMI hot plug event: Codec=3 Pin=6 Presence_Detect=1 ELD_Valid=1
      alsa => [ 4561.303322] HDMI status: Codec=3 Pin=6 Presence_Detect=1 ELD_Valid=1
      alsa => [ 4561.311120] ALSA hda_eld.c:259 HDMI: Unknown ELD version 0
      
Hey the two parts are interleaved!

But still it should work all fine, since the gfx driver does

        set ELD_Valid = 0
        write ELD
        set ELD_Valid = 1

So the audio driver would read the correct ELD unless the ELD content
and flag writes are somehow _reordered_ underneath. Or the ELD content
writes take some time to take effect?

Thanks,
Fengguang

Just confirmed that adding 1s delay can fix it!

My test steps are

1) fresh boot
2) cat /proc/asound/card0/eld* ==> OK
3) startx
4) DISPLAY=:0.0 xrandr --output HDMI2 --mode 720x480
5) cat /proc/asound/card0/eld* ==> ZEROS before patch, OK after patch

I guess avoiding the extra ELD passing can also fix this problem,
since we never meet timing problems with the first HDMI hot plug event.

Thanks,
Fengguang

Wow, you were able to reproduce it! That's the best news ever. I will be 
applying this patch and rebuilding now to see what happens. So it was 
some sort of timing issue after all.

Expect me to reply within 1h, but rebuild takes some time.

I still had the old build directory and only had to rebuild one module 
which only took 5 minutes. The rest of the delay was me doing an hour of 
tests as well as being on a 45 minute phone call. Anyway, now the result:

Success!

So we know it's a timing issue somewhere. Wow, real progress and near a 
solution. Finally! The big question now is what causes the audio driver 
to read the ELD while it is empty, and why the 1 second delay fixes it.

Look at speakertest.txt here. It's beautiful. ;-) Playing digital 
multichannel sound over the HDMI PCH bus, and I can hear every channel 
in their proper location on my speaker system. It's beautiful. I've 
waited for this moment since building this Linux HTPC back in April. ;-) 
(I'm an astonishingly patient man hehe).

Now as for why we needed a 1 second delay, any ideas? Could it be that 
the audio driver was reading the ELD while it wasn't written to the 
register yet?

Maybe not necessarily 1 second.  It could do some loop with a small
delay until it reads zero-size?  Or if it really can take long time
like 1 second, it'd be better to be a work to self-reschdule to do in
background, as it's called at the probing time and at each unsol
event.  Since radeon sends really zero-byte ELD when a DVI monitor
without audio is connected, stalling one second there is no good
choice.

Hopefully this delay would fix the zero-size problem we are currently 
working around in an ugly way (the comment mentions about ASUS P5E-VM
HDMI board), too.


thanks,

Takashi

Well yes obviously the 1 second delay is a temporary workaround until 
the real cause is found. Something like what you suggested should be the 
final fix; a real loop that proceeds only when the data is ready (with a 
1 second or so maximum loop time, to avoid infinite loop if data never 
becomes ready).

I don't think a background schedule would work, because the data needs 
to be available at boot BEFORE the audio layer loads. Otherwise ALSA 
(for example) would load while no data had yet been read into the ELD 
registers. If a background schedule is used, then GREAT care must be 
taken to make sure it finishes before the audio layer launches.

In theory, the delayed probe and notification can be handled just like
a hotplug case.  We have still no notification framework (especially
in PulseAudio) yet, though :)

Yep that is the main risk of a delayed event - a possible inability to 
re-configure the audio layer.

I think ALSA *might* be able to re-detect audio devices and settings 
after the initial boot, because I know there is a MANUAL "alsa 
force-reload" command. I am pretty sure it doesn't run automatically 
when the Intel driver detects a hotplug, though. That would require some 
sort of notification between the Intel driver and ALSA which afaik 
doesn't exist. Then there's also the problem that applications could 
start using the audio layer in its bad state and won't like the 
unexpected reconfigure.

This means that once the ALSA layer has loaded with a bad config, it's 
stuck like that. Therefore the biggest priority of the final solution 
will be to ensure that all ELD data is ready *before* ALSA (or any other 
audio layer) first queries it, so that the system boots into the proper 
audio state right away.

We already know that it takes less than a second to have ELD ready from 
the point that the ELD function has been entered, so a small loop with a 
1 second max execution time (to prevent infinite) could be good enough. 
It would be interesting to try such a loop along with a small counter, 
and a 10ms or so wait between iterations, and then printing the number 
of iterations to the debug log. That will show us how long the average 
wait for valid ELD is.

Yes it's a quick hack to confirm the idea. The initial try is 100ms
delay but it's not working. So I took a big jump ;-)

I'll experiment with smaller values.

I definitely would like to know the root cause.  Does it simply need
some time to take effect, or have some explicit "ready to go" condition?

It looks ridiculous the hardware provided "ELD valid" flag does not
guarantee the availability of new ELD content.

The more confusing thing is, why it reads 0 at all? The i915 ELD code
will never reset or write zeros to the hardware ELD buffer.

So maybe the hardware is in some state that is unable to provide the
real ELD content?

Maybe we can do with the simple sleep-and-retry if it only requires
200ms delay? Anyway let me try work out the time first.

That's my guess as well. I think the hardware may still be doing some 
form of data negotiation with the HDMI display device at that stage, and 
doesn't have the copy of the EDID+ELD buffer until a tiny bit later. 
Possibly?

Yeah. If you have time, do something that looks for ELD availability in 
a loop with msleep(10) and count how many iterations it takes to see the 
data. That'd be the most granular approach.

You don't have to do so much things.  The HDMI codec is there
statically, and the corresponding device is already created at boot
even the ELD probe is delayed.  What would change after the ELD probe
is the information of the PCM stream, i.e. the supported format,
channels, etc.

Right, this has been discussed recently, and I'm already working on
it.  PA will have some support for jack-detection, and HDMI driver
will issue a jack-notification as well.

Then it falls back to the basic 2-ch stream, so usually not too
critical for "normal" users :)

No, the driver shouldn't be stuck at the boot time at all.
If ELD probe is pending, user-space can sync at the first open, for
example.  Remember that the device itself already.  Blocking in the
driver probe time is simply bad.

The problem is, as mentioned, the case where the hardware really sends
zero-size ELD.  In this case, it stops until the defined time-out.

This is the first step, indeed.

Look at the below dmesg. The ELD seem to available immediately after the DPMS
state setting..

Got the delay - it's 72.986623-72.747632 = 239ms.

I wonder if the DPMS line has anything to do with the delay...

Nice find! It does seem likely since the ELD read worked right after 
that. Hmm. I am not familiar with the event order for the Intel 
hardware, and what's calling your edid_to_eld code, etc. Is it possible 
to move the EDID read call to after the DPMS state is ready?

Interesting.  Does HDMI audio work at all while HDMI DPMS off?
It clears SDVO_ENABLE bit, so this might turn off both video and
audio?

I added a dump_stack() at the very beginning of drm_crtc_helper_set_config().

Judging from drm_crtc_helper_set_config()'s comment and the below dmesg, it's
called by user space.

So audio driver got the ELD right after drm_crtc_helper_set_config() returns.

It shows that ironlake_write_eld() is ultimately called by
drm_crtc_helper_set_config().

We normally see transient blank screen and silence of audio when
switching the video mode.

The spec says that at this short stage the HDMI/DP audio driver should
take NO action like stopping the audio stream -- just let go of it for
the moment.

The above dmesg is associated with very simple assignment code, so
should be irrelevant.

Here, 84.996 should be the last retry time, and ELD is still not
ready.

The below intel_prepare_page_flip() is actually a no-op. So we lose
the obvious clues...

Well, what I suspected is that ELD won't be transferred while
SDVO_ENABLE is cleared.  And I'm not sure whether HDMI audio is played
while DPMS is off.  I haven't tested it.

Unfortunately I can't test it right now since my colleague is using a
desk where the HDMI monitor is on...

It's not about SDVO_ENABLE. The transient ELD invalid state I see in
dmesg is caused by the graphics driver doing

        ELD_Valid = 0           => trigger 1st unsolicited event
        write ELD contents
        ELD_Valid = 1           => trigger 2nd unsolicited event

The two unsolicited events are described in "Figure 72. PD and ELDV
unsolicited responses flow for digital display codecs" of the High
Definition Audio Specification Rev. 1.0a.

                [  467.574207] [drm:ironlake_write_eld], ELD on pipe B
                [  467.579346] [drm:ironlake_write_eld], Audio directed to unknown port
                [  467.584724] [drm:ironlake_write_eld], ELD: DisplayPort detected
1st event =>    [  467.586540] HDMI hot plug event: Codec=3 Pin=7 Presence_Detect=1 ELD_Valid=0
                [  467.599608] [drm:ironlake_write_eld], 
1st event =>    [  467.599922] HDMI status: Codec=3 Pin=7 Presence_Detect=1 ELD_Valid=0
                [  467.605834] ELD size 9
                [  467.610434] [drm:sandybridge_update_wm], FIFO watermarks For pipe A - plane 7, cursor: 6
2nd event =>    [  467.612365] HDMI hot plug event: Codec=3 Pin=7 Presence_Detect=1 ELD_Valid=1
                [  467.620654] [drm:sandybridge_update_wm], 
2nd event =>    [  467.620765] HDMI status: Codec=3 Pin=7 Presence_Detect=1 ELD_Valid=1

Depending on the timing, the 1st unsolicited event may see
ELD_Valid=0 (if it's fast enough) or ELD_Valid=1 (if the event
handling is delayed after the graphics driver sets ELD_Valid=1).

I know that because I literally saw both cases happening in dmesg.
The 1st hot plug event itself will send ELD_Valid=0, however the audio
driver is not trusting this and always do a status query (the HDMI
status line) whose result depends on the timing.

It will go silence on DPMS. I noticed this while doing long term HDMI
audio playback tests.  This should better be fixed in future on the
graphics side.

I'm always borrowing HDMI/DP monitors and test boxes, too ;-)

But why this triggers at *plugging*?  Wasn't it zero beforehand?
If I understand correctly, changing AUD_CNTL_ST register triggers the
HD-audio codec unsol event.  Writing even the same value matters?

The problem in this procedure is that this looks as if you are
re-connecting the HDMI from the audio-codec POV.
We might end up with some delayed probe with a dedicated work_struct
(because it's bad to have a too long delay in unsol event handler
 that run on a single workq).

Hm, but I wonder what could be done alternatively.
Hopefully there is a register for video-only control...

Sorry I assumed the "mode switching" context. On hot plugging,
clearing the already 0 ELD_Valid won't trigger the 1st unsolicited
event.

The re-connecting events can be distinguished from the
video-mode-switching events by the Presence_Detect bit.

Here is one hot removal event (I just wrote a patch to trigger this),
with Presence_Detect=0:

[   91.777028] [drm:ironlake_write_eld], ELD on pipe B 
[   91.778561] HDMI hot plug event: Codec=3 Pin=6 Presence_Detect=0 ELD_Valid=1
[   91.783078] HDMI status: Codec=3 Pin=6 Presence_Detect=0 ELD_Valid=0
[   91.783083] [drm:ironlake_write_eld], Audio directed to unknown port
[   91.783095] [drm:output_poll_execute], [CONNECTOR:12:HDMI-A-2] status updated from 1 to 2

The HDA spec even mentioned doing some timeout mechanism for the
"Presence_Detect=1 ELD_Valid=0" state. Well it may help some corner
cases, but perhaps not an urgent feature.

Understand. What if the graphics driver can delay the ELD writing (I
can try that), so that the audio driver only need to wait for
something like 10ms?

There may be some mode that can keep video off while still keep
minimal signals to play HDMI sound?

Ah, I see.  But this could be suppressed by your patch
   drm/i915: don't trigger hotplug events on unchanged ELD
no?

Hm, OK, so the codec driver can simply ignore (or postpone) the case
when the connection is kept but ELD is invalidated.

One note that we don't rely on PD bit because not all (non-Intel)
hardware report it correctly.

Yeah, this sounds like the workaround for such a case.

Or, we can introduce a dirty flag, and set it when ELD is changed,
but don't prase ELD contents yet.  First upon the next access, the
driver updates the status, and clear the dirty flag.  We may put a
small delay at this update, too.

Mostly. The ELD may still change if the mode switching changes the
av-sync-delay field, or suppresses the bandwidth available to audio
samples.

Yeah, your mentioned DVI case may be always in state

        "Presence_Detect=1 ELD_Valid=0"

where audio playback should be denied.

And there might be the error case that the 2nd event is lost or not
generated at all for changing

        "Presence_Detect=1 ELD_Valid=0"
to
        "Presence_Detect=1 ELD_Valid=1"

It should work fine for "cat /proc/asound/card0/eld*" and other
interfaces, however it could still delay the printks' significantly.

And it feels not good that accessing ELD may be blocked for some time..

So I now prefer to avoid the msleep totally and schedule a delayed
work for parsing ELD.

Oh hell, no :)
The driver tries to probe explicitly via GET_PIN_SENSE HD-audio verb.

Maybe not. How about the attached patch to remove them all?

I guess yes.  At least, it worked with Nvidia and ATI, too, so far.
The point is that the value passed in the codec unsol event is
unreliable for some chips.

I'm fine with it (better after debugging the ELD problems :)

Yeah, for example the below "HDMI hot plug event". When device is hot
removed, Presence_Detect and ELD_Valid both goes 0, but the driver has
to clear them one by one. As I choose to disable SDVO_AUDIO_ENABLE
first, we see the strange "Presence_Detect=0 ELD_Valid=1" combination
below.

OK, when all the ELD/hotplug stuff calms down.

Looks very possible, here is the clue of hardware support:

        TRANS_DP_CTL - Transcoder DisplayPort Control

        bit 26: Transcoder DP Audio Only Mode

Good to know!  But what about HDMI?

I'm not sure.. There are no corresponding TRANS_HDMI_CTL registers...

You can turn off only the plane (but don't turn off the pipe & port) to achieve this.

Not much of power saving compared to DPMS though.

Bit 26 of TRANS_DP_CTL does not work. Also there is no such bit for HDMI.
