[Nouveau] nouveau: kernel rejected pushbuf: Invalid argument

[Li, Stephen]

Thanks for your response. I am able to capture a few more lines of the dump (see console-output.txt). dmesg output attached.

My bitmap is 720x512. Below is the library versions, and amount of vram.

Any feedback is appreciated.

Thanks.
Steve

The rest of this dump can provide useful information.

Also what was logged in dmesg? It will have the reason why the kernel hated this submit.

Also... what hardware do you have (lspci -nn -d 10de: output would be great)? libdrm version? mesa version?

How big is your texture? How much VRAM do you have?
