https://bugs.freedesktop.org/show_bug.cgi?id=73781 Priority: medium Bug ID: 73781 Assignee: dri-devel(a)lists.freedesktop.org Summary: [r600g] SIGFPE at at ../../../../../src/gallium/drivers/r600/r600_state.c:3 109 Severity: normal Classification: Unclassified OS: Linux (All) Reporter: ahmabdabd(a)hotmail.com Hardware: All Status: NEW Version: unspecified Component: Drivers/DRI/R600 Product: Mesa Created attachment 92368 --> https://bugs.freedesktop.org/attachment.cgi?id=92368&action=edit Proposed solution patch chipset: RV740 system architecture: x86_64 libdrm-dev: libdrm (2.4.50-1) unstable kernel version: 3.12-1-amd64 Linux distribution: Debian Sid x86_46 Description The driver crashes when running the new instancing sample from the sample browser of Ogre3D (latest stable v1.9) Steps to reproduce: 1) Run the Ogre3D sample browser. 2) Load the "New instancing" Sample. 3) Change the Technique to "Hardware instancing+VTF" 4) The application crashes with "Program received signal SIGFPE, Arithmetic exception." Attached a full backtrace and the output of glxinfo. Suggested Cause: This problem occurs when large vertex textures whose width (pitch) is greater than 4095 pixels and pixel format R32G32B32A32 causing the texture width to be greater than 65536 which causes division by zero in line 3109 cheight = ((0x0000ffff << 2) / pitch) & 0xfffffff8; ncopy = (copy_height / cheight) + !!(copy_height % cheight); in src/gallium/drivers/r600/r600_state.c Suggested Solution: Attached is a diff of a suggested solution to consider textures whose width is greater than 4095 pixels and avoid the crash. (Note the diff is against the 10.0 branch but it should work with 9.2 as well) Full backtrace: Program received signal SIGFPE, Arithmetic exception. 0x00007f131462dcb6 in r600_dma_copy_tile

[Bug 73619] New: XServer frequently freezes for a few seconds

https://bugs.freedesktop.org/show_bug.cgi?id=73619 Priority: medium Bug ID: 73619 Assignee: dri-devel(a)lists.freedesktop.org Summary: XServer frequently freezes for a few seconds Severity: normal Classification: Unclassified OS: All Reporter: arichardson.kde(a)gmail.com Hardware: Other Status: NEW Version: 10.0 Component: Drivers/DRI/R600 Product: Mesa The XServer randomly freezes for a few seconds or sometimes even 1-2 minutes. I cannot move the mouse, and the screen does not update. I have a HD4850 card running on a 3.12.6-1.g080d0df-desktop SMP PREEMPT x86_64 kernel with Mesa 10.0.1 (both from openSuSE packages). These freezes also happen with the default 3.11 kernel, I upgraded in the hope of it being fixed, but the issue is still present. These issues started after the upgrade to openSuSE 13.1 which has a 3.11 kernel instead of the previous 3.7 kernel. The Mesa version did not change, I was always running the latest released version. My guess is it has something to do with the r600 kernel changes in 3.8+. During these freeze periods I can ssh into my system and top shows no CPU usage, so the XServer seems to be sleeping instead of being in a busy loop. dmesg gives me no messages and /var/log/XOrg.0.log is also empty. I don't know how to get any more detailed logging output. If you provide me with the necessary environment variables/kernel parameters I will give you these logs. Not sure if this helps, but most of the time the freeze happens when I open a new tab in firefox or switch to a different one. However it also happens at random intervals using other programs. It can sometimes take quite a long time until this freeze happens, however once it has occured once, it usually happens again after a short timespan (1-2 minutes or even less). Is it possible to debug the XServer just like a normal program using gdb? If yes I will try to provide a useful backtrace once the next longer freeze happens -- You are receiving this mail because: You are the assignee for the bug.

Severity: normal Classification: Unclassified OS: All Reporter: adam(a)aphirst.karoo.co.uk Hardware: x86-64 (AMD64) Status: NEW Version: 10.0 Component: Drivers/Gallium/r600 Product: Mesa Created attachment 91790 --> https://bugs.freedesktop.org/attachment.cgi?id=91790&action=edit mpv verbose log, when video decodes successfully This is somewhat difficult to explain. * AMD PALM E2-1800 APU * Arch Linux x86_64 * Kernel 3.12.6-ck (also with vanilla 3.12.6) * mesa 10.0.1, xf86-video-ati 7.2.0 One of the following three situations occurs, seemingly at random, when opening an mpeg4 video file using any player which supports vdpau hardware-decoding (e.g. mplayer r36498, VLC 2.1.2, mpv 0.3.2) 1. The video decodes and plays just fine 2. The video decodes incorrectly, with bright-green garbling, and general smearing 3. The video decodes and plays fine, BUT with a couple of small artefacts either in the player window, or anywhere on the screen (the artefacts are little black squares, inside which are a few fluorescent-coloured pixels flickering) The interesting point is that, on the same file, you can close and re-open the video player and receive a different random outcome each time. I'm in the habit of trying a few times to open my .avi videos until it "just works". This is not the same as the mpeg4 ASP garbling issue which I reported a month or so ago, which was 100% consistent on the affected files. For this bug, the files which display *this* problem are 'normal' mpeg4 videos, and whether or not decoding succeeds appears to be completely random. Frustratingly, neither the video player's verbose logs, nor the DPM messages in dmesg, indicate anything *at all* different between successful and unsuccessful attempts. I'll upload to this report a couple of log files, including the outputs of ffmpeg -i on a selection of affected files. I'll also upload some video samples, bear with me. -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.freedesktop.org/show_bug.cgi?id=73444 Priority: medium Bug ID: 73444 Assignee: dri-devel(a)lists.freedesktop.org Summary: wayland/weston EGL/GLESv2 - top portion of screen in fullscreen: vertices being clipped/flicker Severity: normal Classification: Unclassified OS: Linux (All) Reporter: emiettin(a)edu.lahti.fi Hardware: x86-64 (AMD64) Status: NEW Version: 10.0 Component: Drivers/Gallium/r600 Product: Mesa In fullscreen wayland/weston EGL/GLESv2 clients without X11 (as in weston launched from a tty), vertices ending up on the top 5-10% portion of the vertical screen space are being clipped (as in seemingly skipped altogether and disappearing), despite setting up an appropriate projection matrix + calling glViewport. This results in flickering sawtooth-like edges on the top of the screen area. This effect doesn't show up - in windowed mode - in screenshots (weston Super+s) - in screen capture (weston Super+r) - while zoomed in using the weston Super+mwheel shortcut, or - when using weston through X11. Asking about this on #dri-devel on Freenode lead to the following hypothesis by pq: 12:30 < pq> so if super+s, or zoom, or having it in a window makes the problem go away, then the fundamental difference is likely that when weston composites, everything goes well, but when weston tries to scan out the client image directly, something breaks. This occurs at least in mesa 9.2.x through git master. setup: Arch Linux x86_64 3.12.6-1, Radeon HD 5770 w/ {ati-dri, mesa, mesa-libgl}-9.2.5-1, -10.0.1-1, or -git wayland-1.3.0-1, weston-1.3.1-2 or git. -- You are receiving this mail because: You are the assignee for the bug.
