Hi,

KMS with radeon driver doesn't work properly using the svideo output connected
to a CRT TV.

See startup with and without KMS :
http://aprovin.linux62.org/others/forums/kms/startup_with_kms.mp4
http://aprovin.linux62.org/others/forums/kms/startup_without_kms.mp4

I tested with 3.2, 3.1, 2.6.39, 2.6.32 kernels. The bug is present.

Because of this bug, it's impossible to use a X session (color and resolution
corrupted).

I built a custom kernel (3.2.2) with debug flags enabled for radeon driver. See
the dmesg.

If you need others informations or I test a patch, I'll do it with pleasure.

Regards,

Aurélien PROVIN

Looks like the radeon driver uses NTSC output by default, can the TV handle
that?

I don't know if this TV supports NTSC but it supports PAL and SECAM.

Is it possible to force driver to use PAL by a kernel option or by a patch ?

xrandr --output S-video --set "tv standard" pal
use xrandr --verbose to double check the output and attribute name for your
board.

I can confirm it's not a cable problem or a TV problem (Tested with Windows 7
on the same config : no problem)

Please grab radeonreg (http://cgit.freedesktop.org/~airlied/radeontool/) and
dump the display registers with KMS and without KMS (as root).

./radeonreg regs avivo > working.regs

and

./radeonreg regs avivo > broken.regs

And attach the outputs here.

The only difference seems to be which crtc is driving the TV.  Can you try
booting with only the DVI port connected, and then connecting the TV later once
your desktop is up with both KMS and UMS?

Well, I'll do it in the evening when I'll be home. Simply plug the TV or turn
on the output and adjust the resolution?

Boot up without the TV attached to the video card, then when your desktop is
up, use xrandr to turn on the TV connector and adjust the mode, etc.  Does it
work any better or worse in either case (UMS or KMS)?  What exactly did you do
to generate the files you attached?

> Boot up without the TV attached to the video card, then when your desktop is

Yes. I did exactly. 
I first boot the system with KMS. Plug the TV. Launched
# ./radeonreg regs avivo > rv570.kms.turn_off
Then set up S-video output in systemsetings (kde). Launched
# ./radeonreg regs avivo > rv570.kms.turn_on

In the same way rv570.ums.turn_off and rv570.ums.turn_on are created (UMS).
With UMS all good. With KMS screen TV is striped.

Please attach a copy of your video bios.  

(as root)
(use lspci to get the bus id)
cd /sys/bus/pci/devices/<pci bus id>
echo 1 > rom

For some reason the entire secondary display path is disabled (tv encoder, dac,
crtc) with KMS on your system for some reason.  I can't reproduce it here
unfortunately. Does the following help?  

./radeonreg regset 0x000004f4 0x80000062
./radeonreg regset 0x00005e00 0x00000001

I'm back. I'm sorry for the delay...

I started computer with only DVI connected with KMS enabled.
-> xrandr --verbose (KMS-xrandr1-notv)
I connected the S-video cable
-> xrandr --verbose (KMS-xrandr2-tv-connected)
-> ./radeonreg regs avivo (KMS-radeonreg-just-connected)
-> xrandr --output S-video --auto
-> xrandr --verbose (KMS-xrandr3-tv-activated)
-> ./radeonreg regs avivo (KMS-radeonreg-connected-activated)

I started computer with only DVI connected with KMS disabled.
-> xrandr --verbose (UMS-xrandr1-notv)
I connected the S-video cable
-> xrandr --verbose (UMS-xrandr2-tv-connected)
=> TV not detected
-> ./radeonreg regs avivo (UMS-radeonreg-just-connected)

I also add ./radeonreg regs avivo without X session :
kms-radeonreg-noX
ums-radeonreg-noX

There is no change with your patch :
- dmesg (dmesg-patch-noX)
- dmesg (dmesg-patch-withX)

I also attach vbios.rom

Alex, I have news. Today I ran the system with the KMS enabled and then sent
the computer into standby mode. After leaving the sleep mode on the TV image
was fine. In the file contents of the registers. I hope this will help in
solving the problem. Thank you.
