* [PATCH] PCMCIA: make Pretec CF Wifi use hostap_cs by default
From: Marcin Juszkiewicz @ 2006-04-09 20:39 UTC (permalink / raw)
To: linux-kernel; +Cc: Jouni Malinen, Pavel Roskin
I use two Zaurus palmtops - one run 2.4.18 kernel (it's sl-5500) and second
run 2.6.16. Both are running under control of OpenZaurus distribution
(I'm Release Manager of it).
When I use pcmcia-cs then my Pretec WiFi card is handled by hostap driver
and everything is working fine. Recently I switched to pcmciautils and after
card insert orinoco modules are loaded. I prefer to use hostap modules
because they work the same under 2.4 and 2.6 kernels (with orinoco I have to
use 0.13e ones because never ones does not work under 2.4/arm).
This patch adds definition of my card to hostap_cs cardlist. It was tested on
Sharp Zaurus C760 palmtop running 2.6.16 + pcmciautils 010 + udev 084
PS - I'm not subscribed to that list - so please Cc: me on reply.

Doesn't this condition in addx and the corresponding line in subx need similar

Well, I don't think it would help in this particular case. The memory got divided
almost ideally in swsusp_shrink_memory() and we were hit by the lowmem
reserve in ZONE_DMA, apparently.
Still I've been doing a crash course in mm internals recently and I can say a
bit more about your patch now. ;-)
First, I agree that using balance_pgdat() for freeing memory by swsusp is
overkill, so the removal of its second argument seems to be a good idea to
me. However, I'd rather avoid modifying struct scan_control and shrink_zone()
and reimplement the shrink_zone()'s logic directly in shrink_all_memory(),
with some modifications (eg. we can explicitly avoid shrinking of the active
list until we decide it's worth it) -- or we can define a separate function for
this purpose.
Second, there are a couple of details I'd do in a different way. For example
I think we should call shrink_slab() with the non-zero first argument
(otherwise it'll use SWAP_CLUSTER_MAX) and instead of setting
zone->prev_priority to 0 I'd set vm_swappiness to 100 temporarily
(or maybe l'd left it to the user to set swappiness before suspend?).
Also I think we can try to avoid slab shrinking until we start to shrink the
active zone or IOW until we can't get any more pages from the inactive
list alone.
If you don't mind, I'll try to rework your patch a bit in accordance with
the above remarks in the next couple of days.
Greetings,
Rafael

Confirmed, this patch solves the "badness" problem for me.
I still experiencing a weird hangs though (the box just hangs, no
messages on console/syslog, nothing). I'll try to nail it down.
2.6.16-mm2 works like a charm with the same config.
Do you know which patches should I try to revert first?

don't you mean _3_ chunk-sized writes? if so, are you actually
asking about the case when you issue an aligned two-stripe write?
(which might get broken into 6 64K writes, not sure, rather than
three 2-chunk writes...)

I guess you refer to "hardware handlers" modules. Those are needed only

This is often the case with asymmetric arrays.

There is no plan for userspace tools to support lk2.4 (pre-sysfs

Hardware handlers use a "lk2.6 DM" specific API.

Sorry, I thought when you said top-post, I thought you were telling me about only posting the "top" most errors in my original e-mail, thats why i pasted full error output.
The thing is, it compiles successfully when CONFIG_NET_SCHED is not enabled in the kernel. But when its not enabled, i get the external symbol errors.
As soon as I enable CONFIG_NET_SCHED ... it no longer compiles.
I will look into this, it is supposed to work... the code has been used by others before.
If you or anyone else come up with anything, please let me know
Thanks!

[repeat: please don't top-post]
I don't know how much I can help you. It's been a long time since
I've built external modules on 2.4.x.
Problems that I see:
- the Makefile does not use the expected 2.4 kernel build infrastructure;
- kernel Makefile uses -nostdinc to prevent use of userspace headers;
- Makefile is trying to include userspace headers instead of kernel headers, e.g.:
In file included from /usr/include/linux/if_ether.h:107,
from /usr/include/linux/netdevice.h:29,
from sch_xcp.c:8:
- this specified include directory is only in 2.6.x, not 2.4.x:
-I/lib/modules/`uname -r`/build/include/asm/mach-default
It's not clear to me how this makefile could work with 2.4.x at all.
Is it supposed to, or that's just what you want to see it do?
You could try to fix the Makefile based on makefile-changes articles at lwn.net.
E.g.:
http://lwn.net/Articles/151784/
http://lwn.net/Articles/79984/
http://lwn.net/Articles/74767/

Summary: Issue 001595 does not fix Audigy 4
Description:
I have an Audigy 4 with the same device/subsystem as khampf from issue
1595. I applied his patch, but it does NOT work unless I change
.ca0102_chip = 1 to .ca0108_chip = 1.
I did experience the same confusion where loading one driver with ca0108
will make any subsequent driver work (e.g., ca0102) until the next reboot.

----------------------------------------------------------------------
As 0001595 has been closed, I would just like to confirm, that Audigy 4
_partially_ works with entry
{.vendor = 0x1102, .device = 0x0008,
.driver = "Audigy2", .name = "Audigy 2 Value [Unknown]",
.id = "Audigy2",
.emu10k2_chip = 1,
.ca0108_chip = 1,
.ac97_chip = 1}
I have a 5.1 speaker set and I do not get sound from front left and front
right speakers. I tried to set up reasonable levels on every output with
alsamixer, but without success. I tried patching the Audigy 2 entry in
emu10k1_main.c to specify .spk71 = 1 - it did not have any influence.
Replugging front left/right minijack from its corresponding socket (L1)
into the center/subwoofer socket (L3) as reported by 'kjes' in discussion
for 0001595 is not a solution as then I loose subwoover and central
speaker.
I am now running unpathced 2.6.15.2 on AMD-64 (64-bit kernel) with Audigy
4 being the first of two soundcards (the second one is an integrated AC97
clone on the motherboard).

It should never be NULL. If anything that's a BUG_ON, but crashing on it is ok
too.
But I'll change it to a BUG_ON in the next patch thanks.

The statistics you posted seem to be fine. Which interface counters are
you talking about? tc starts counting only after the qdiscs/classes were
created, so if you have a separate count somewhere which started counting
some other time, the difference will of course be huge (as far as total
packet count is concerned).

In-Reply-To: <200604081221.58080.sgrubb@redhat.com>
Hi,
Based on finding an unnecessary function call to selinux_task_ctxid when
evaluating syscall rules, I built a new kernel and re-ran the same tests.
rules seconds loss
0 47 0%
10 53 11%
25 68 43%
50 99 109%
75 132 178%
90 157 232%
The 75 rule performance hit is now 178% instead of 184%. So there is some
notable improvement in performance.
For comparison, I also loaded the 90 rules config into RHEL4. There is only a
6% performance hit compared to no rules. I think the bulk of that comes from
evaluating the 10 syscall rules rather than the file system audit code.

Summary: MSI K8N's SB Live 24 bit, no sound from line-in
Description:
I have a MSI K8N Platinum motherboard that has a SBLive! 24 bit
integrated.
(Un)fortunatelly this motherboard provide two different jacks for Mic and
Line-In instead of one single jack like the pci version of the sb live 24
bit.
With this card I cannot hear any sound that come from line-in.
For Example I have a tv card, its output audio go into line-in: result is
I cannot hear nothing from the tv, I can only see channels without audio.
The "Capture feedback into playback" in the mixer change the mic's
volume.
There is nothing that change line-in's volume.

* [ALSA - driver 0001331]: MSI K8N's SB Live 24 bit, no sound from line-in
From: bugtrack @ 2006-04-09 19:40 UTC (permalink / raw)
To: alsa-devel
The following issue has been ASSIGNED.
======================================================================
<https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1331>
======================================================================
Reported By: Cimmo
Assigned To: jcdutton
======================================================================
Project: ALSA - driver
Issue ID: 1331
Category: PCI - ca0106
Reproducibility: always
Severity: trivial
Priority: normal
Status: assigned
Distribution: Fedora Core 4
Kernel Version: 2.6.12-1.1398-x86_64
======================================================================
Date Submitted: 08-13-2005 01:27 CEST

Summary: MSI K8N's SB Live 24 bit, no sound from line-in
Description:
I have a MSI K8N Platinum motherboard that has a SBLive! 24 bit
integrated.
(Un)fortunatelly this motherboard provide two different jacks for Mic and
Line-In instead of one single jack like the pci version of the sb live 24
bit.
With this card I cannot hear any sound that come from line-in.
For Example I have a tv card, its output audio go into line-in: result is
I cannot hear nothing from the tv, I can only see channels without audio.
The "Capture feedback into playback" in the mixer change the mic's
volume.
There is nothing that change line-in's volume.

In order to help me implement support for what you want, please try the
following:
arecord -fdat -Dhw:0,0 | aplay
arecord -fdat -Dhw:0,1 | aplay
arecord -fdat -Dhw:0,2 | aplay
arecord -fdat -Dhw:0,3 | aplay
Please tell me which one works for the "line in".
If should record from the line in and then play it to the speakers with a
small delay.

It's clearly a driver bug so all you can do at this point is wait for a
response from the driver developer.
----------------------------------------------------------------------
jcdutton - 09-10-05 10:31
----------------------------------------------------------------------
You might have an older version of the kernel driver.
Please post the output of: http://alsa.opensrc.org/TroubleShooting
Do Questions 1,2,3 and 4 and post the output here.
If you find that you do not have the latest alsa-driver, please try to
upgrade to it.
Please note that Line-in has never ever worked for your motherboard based
sound card in Linux, due to lack of enough information to implement it.
So, it is not really a bug, but instead a feature that we don't know how
to implement yet.
----------------------------------------------------------------------
Cimmo - 10-19-05 19:13

1) Alsa is installed via module. Actually I've kernel v2.6.12.9
2) Advanced Linux Sound Architecture Driver Version 1.0.9 (Sun May 29

jcdutton - 11-07-05 00:02
----------------------------------------------------------------------
The version of alsa-driver you have is too old.
Support for your sound card was only added recently.
Please upgrade your version of alsa-driver.
If you compiled your own kernel, then simply installing alsa-driver will
update them for you.
----------------------------------------------------------------------
Cimmo - 11-07-05 11:07
----------------------------------------------------------------------
So I've to switch to development version 1.0.10rc2?
----------------------------------------------------------------------
Cimmo - 11-11-05 19:33
----------------------------------------------------------------------
Ok I've compiled and installed succesfully alsa-driver and alsa-lib
1.0.10rc3
I've retested everything:
putting TV audio output to mic it works great, I can listen to TV!
With this configuration I'm be able to record and play with these 2
commands:
arecord -fdat -Dhw:0,1 | aplay
arecord -fdat -Dhw:0,2 | aplay
with line-in there is no chance: audio doesn't work, and none of the four
0,x works.
I've to stress Creative for documentation?
Tell me something
Thanx
Marco
----------------------------------------------------------------------
jcdutton - 12-13-05 13:16
----------------------------------------------------------------------
Ok, so now the mic in works, but line in does not.
The only way to fix this is if I get a hardware sample.
The connections of the mic and line in are hardware specific and different
from all other SB Live 24bit cards.
You could try and get MSI to send me a hardware sample if you wish to fix
this.
----------------------------------------------------------------------
Cimmo - 12-13-05 13:34
----------------------------------------------------------------------
Of course send to you a sample means that I have to pay for this and can't
do this :)
The only thing I can do is to give and ssh login to my pc to try via
remote, it can help you?

No, it just a really anoying bug with the autobuild system, and I've
been sick and haven't gotten around to fixing it.

In arch/ppc/configs of the (DENX) 2.4 kernel are plenty of
configurations for the PowerPC boards, e.g. TQM8620_defconfig,
icecube_5200_defconfig, TQM866M_defconfig, etc. But we need cross
compilation for most of the embedded boards. Do you need the
configuration with IPIPE and Xenomai options enabled?

We simply use remote controllable power switches to switch the boards on
and off.

As far as i can test, yes, it works fine. I will forward your
suggestion to -netdev@.
Btw, many thanks to both of you, Andrey and Sergey, for the fast
answers and crystal-clear explanations of the actual issue.

Actually clearing the memory can be done at full memory bandwidth
which can happen in seconds. On systems with ECC you need initialize
all of the check bits so some kind of write to memory needs to happen.
In practice a reset does not clear the memory and only a few bits
tend to get flipped. Unless you can get support from the
BIOS/firmware developers it isn't a practical approach though.

Does a kernel really need 64M? That number seems insanely large
to me. 8M should be more than sufficient if someone actually
tried to be small. If you are aiming for a dedicated hardware
solution you don't need even need a kernel in there and the
amount reserved could be reduced to less than a meg.
The size etc becomes a trade off between what is expedient
and maintainable.

Fair enough. At that point the counting does have to be done in the
caller, I guess.

Yes. The fact that git-whatchanged happens to ignore such things right now
is just a implementation detail, not a "good thing". The new git log seems
to be better in pretty much all respects.
The bigger conceptual difference is actually that once you do revision
pruning based on the pathname limiter, we prune away parents of merges
that seem "uninteresting". So before, when you had the same change come
through two different branches, "git-whatchanged" would actually show it
twice, while the new "git log" approach would tend to show it just once
(because it would pick one of the histories and ignore the other).
I think that's fine (and probably even preferable), but it's another
example of something where we might want to have an option to not
simplify the merge history. It's likely that nobody will ever care, but
who knows..
