dmesg

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

Comment 1 Aur 2012-02-04 12:25:00 UTC

My video card is an 'ATI Technologies Inc RV516 [Radeon X1300/X1550 Series]'

Comment 3 Michel Dänzer 2012-02-09 09:13:35 UTC

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

Comment 4 Aur 2012-02-09 17:48:16 UTC

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 ?

Comment 5 Alex Deucher 2012-02-09 18:29:24 UTC

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

xrandr --verbose

I tried to set pal with xrandr :

http://aprovin.linux62.org/others/forums/kms/startup_xrandr_pal.mp4

01m09s -> to pal
01m21s -> to ntsc
01m27s -> to pal

The display change when PAL is set but it's already unreadable and green ...

Comment 7 Egor Y. Egorov 2012-02-26 14:12:23 UTC

same problem on my system with
VGA compatible controller: ATI Technologies Inc RV570 [Radeon X1950 Pro] (rev 9a)

Comment 8 Aur 2012-02-26 17:41:11 UTC

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

Comment 9 Egor Y. Egorov 2012-02-27 02:13:36 UTC

Yes. With Windosw 7 and on linux without KMS all right.

Comment 10 Alex Deucher 2012-02-27 13:54:19 UTC

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.

with kms

Comment 13 Alex Deucher 2012-02-27 15:31:08 UTC

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?

Comment 14 Egor Y. Egorov 2012-02-28 02:10:54 UTC

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?

Comment 19 Alex Deucher 2012-02-28 15:50:12 UTC

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?

Comment 20 Egor Y. Egorov 2012-02-28 16:29:33 UTC

> 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.
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.

possible fix

Does this kernel patch help?

Comment 22 Egor Y. Egorov 2012-03-01 13:39:51 UTC

Unfortunately the patch did not help. Everything remains as before.

Comment 23 Alex Deucher 2012-03-01 14:40:44 UTC

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
cat rom > /tmp/vbios.rom
echo 0 > rom

What mode are you trying to use on the TV?  Can you attach the output of xrandr --verbose with KMS?

Can you attach the dmesg output with that patch applied?

Comment 29 Alex Deucher 2012-03-01 16:26:05 UTC

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

Comment 32 Aur 2012-03-03 10:03:13 UTC

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, where can I read the description of the registers for the rv570?

Comment 47 Alex Deucher 2012-04-01 13:03:20 UTC

See the documents linked from the bottom of this page:

See the M56 and rs690 pdfs.

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.
