[Nouveau] Xvideo blitter with randr12 enabled

Wed Sep 5 09:11:01 PDT 2007

Arthur asked me for my status of the blitter with randr12:

The blitter works for me with the Option Randr12 (master branch) enabled as
long as I do not change the startup layout of nouveau which currently always
cloned display on the second monitor to a side-by-side layout with this

xrandr --output Digital-0 --left-of Digital-1

or this

xrandr --output Digital-1 --pos 1680x1050

command (both have visually the same effect)

After I run these commands, the blitter causes a crash, which I hope we can debug.

when I have mplayer running when I run the xrandr to move Digital-1 to the
right of Digital-0, the blitter keeps running but the montiors go into sleep
mode when I quit mplayer. X still keeps running, the last messages are:

output 1 debug_0 01101191
savep->dither 00060000
1: crtc 1 output1: 0100: twocrt 0 twomon 1

and attaching to X with gdb X `pidof X` gives:

(gdb) bt

     envp=<value optimized out>) at main.c:445

I emtied the dmesg buffer with dmesg -c before quitting mplayer but it
does not show new drm debug messages at this point.

I get some messages which might give a clue when starting mplayer after getting
the monitors side by side)

chvt 1 and chvt 7 (back to X) still work, but the chvt 7 does not restore
the X display properly, it seems that the LockUnlock things on console
witch are not working right yet. This reproduces without mplayer ever
started, so that's another thing which I can look at.

When I put the monitors side-by-side before starting mplayer, I get these logs:

Fatal server error:

As Arthur told me that those do not tell anything, here are the drm debug messages:

I should also mention that the two montors go black immedately, then
I hear the sound of the video, and then the sound stops and the X
displays return to text mode with the crash.

That's the printks which I capture with dmesg from start of mplayer
until X starting to crash:

I pressesd dmesg -c >outfile at the time about 2-3 seconds after I started
mplayer, at the same time I pressed return, sound ended and the text mode
restoration was done. I attached the remaining final messages after these 2-3
seconds.

PS: DPMS also does not bring the display back when I after I have put
the mointors side by side with xrandr. For me this DPMS issue could
be easyer to debug, I hope, but first I would like to get the console
switch working as it should and as I had it with my patch to the randr
branch.
