[177.70] IPP2 falling back to IPP1

kriko · 08-31-08, 03:42 AM

Hello!
I've set InitialPixmpmapPlacement to "2" on KDE4 startup - so everytime the computer starts up.
I did some queries with -q switch and saw that it was set to "1" - I thought KDE4 was not starting up nvidia-settings command at startup, so I manually set to 2 and checked parameter this time.
Everything was fine.

This morning KDE4 was not responsive as it should be - I did again a query and saw that IPP is set to "1" again. So definitely something is triggering this - I cannot reproduce it.
Might be because sometime when starting a movie (using OpenGL composite effects under KDE 4.1) the screen will go blank for 1/4 of second - maybe this triggers it, but I cannot reproduce this on demand.
Using mplayer with XV.

Bug report attached.

Another one. Yesterday I was playing with video - but couldn't trigger that.
However this morning IPP was again at 1

Caught it!

Code:

Sep  1 13:22:52 linux kernel: NVRM: Xid (0001:00): 13, 0000 80019700 00004097 00001900 00190005 00000800

As I started to play a clip in mplayer - screen flashed for a sec (blank) and when I checked IPP it was set to 1!

UPDATE: this happened again - I was out on lunch and nothing was going on (workstation locked)
I do use KDE 4.1 effects.

Config settings changing by themselves could actually explain a lot of weird things we've seen here with performance and stability.

I see something similar. When starting nvidia-settings, especially after a few days of uptime, the screen goes black for a few seconds. If I start it again a few minutes later, this does not happen. In the first case it seems to (re-)apply settings that the hardware forgot about.

Thank you for your confirmation! I'm sure that those Xid errors are causing hw to fall back to failsafe settings.

Yes, you're right, the GPU error recovery code in the driver resets InitialPixmapPlacement to its default value.
