Attached is 2 patch for dumping everything needed to replay faulty command stream. I haven't add a module option in the radeon patch but the idea would be to enable the dumping only if it's requested. I know AMD folks would like to reuse AMD internal format, but unless we can quickly get ACK to release it i would rather have this facility in and then latter add a userspace tools that can convert btw this format and the AMD format. The format is described in rati.h, it would be come some kind of API. That's the reason why i changed the whole radeon family files, so it can be share btw kernel and userspace. The replayer is available at: git://people.freedesktop.org/~glisse/joujou replayx replay a rati file under X and show the front buffer of the replayed command stream. It's not yet fully functional but i will work on r6xx with : http://people.freedesktop.org/~glisse/lockup/dump-0000.rati tati convert a rati file to text version so human can alter command stream or buffer to try to find the issue. It's not yet done either idea is to add comment to print register offset next to packet to make it easier. I tested the kernel bits against couple variation of faulty command stream (bad shader, bad vertex count, bad index count, ...) and it seems to work ok. The userspace tools need to grow the unrelocate capacity before being able to replay kernel captured command stream. Mesa patch to dump command stream in same format as kernel: http://people.freedesktop.org/~glisse/lockup/0001-radeong-add-rati-command-stream-dumping.patch libdrm patch needed to either build the joujou or mesa with the patch http://people.freedesktop.org/~glisse/lockup/0001-radeon-add-rati-dumping-helper.patch (Also a bonus is that i regenerated cleanier header definition for r6xx see replayx_r6xxd.h) Cheers, Jerome _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
