[Bug 42913] New: r600g: glx-swap-pixmap causes screen corruption

https://bugs.freedesktop.org/show_bug.cgi?id=42913 Bug #: 42913 Summary: r600g: glx-swap-pixmap causes screen corruption Classification: Unclassified Product: Mesa Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel(a)lists.freedesktop.org ReportedBy: debian(a)carbon-project.org First: I don't think this is bug 40610 because I don't see a crash but screen corruption and (sometimes) the following lines in dmesg: > radeon 0000:01:00.0: r600_check_texture_resource:1346 texture invalid format 0 > [drm:radeon_cs_ioctl] *ERROR* Invalid command stream ! But I'm no Mesa/Piglit expert, so my assumption might be wrong. The Piglit test itself fails, the output is: > Probe at (0,0) > Expected: 0.000000 1.000000 0.000000 0.000000 > Observed: 0.000000 0.000000 1.000000 1.000000 Used stack: Mesa: Git/9ae10e9c libdrm: 2.4.27-1 Kernel: 3.1.1 X.org: 1.11.1.902-1 Let me know, if you need more information. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

Patch to add Cleintron E830 to no-lvds list
by Joel Sass 27 Dec '11

27 Dec '11

Dear developers, I've been directed here by Stephan Graber, and Joseph Salisbury. Stephan has helped me through my first kernel patch, and I am following along with the steps he took pertaining to the following bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/544671 I am working on a bug located here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/907055 and have already submitted a patch. Mr Salisbury recommended I contact the upstream developers in order to have them work this in to the next release, so here I am. I have some Intel 945GM videocard-based thin clients which report LVDS output as active, even though these thin clients do not have a monitor attached. This is causing the clients to boot in dual-head mode, with one monitor missing. Thanks everyone for your time. The bug above has the patch listed in there, but I will include it again below: --- ./intel_lvds.old 2011-12-20 13:25:49.368291249 -0500 +++ ./intel_lvds.c 2011-12-20 13:26:05.160291248 -0500 @@ -709,6 +709,14 @@ }, { .callback = intel_no_lvds_dmi_callback, + .ident = "Clientron E830", + .matches = { + DMI_MATCH(DMI_SYS_VENDOR, "Clientron"), + DMI_MATCH(DMI_PRODUCT_NAME, "E830"), + }, + }, + { + .callback = intel_no_lvds_dmi_callback, .ident = "Asus EeeBox PC EB1007", .matches = { DMI_MATCH(DMI_SYS_VENDOR, "ASUSTeK Computer INC."), ------------------------------------------------------------------------------ Write once.

drm/radeon/kms: How to enable output after it has been disabled on kernel command line?
by Harald Judt 27 Dec '11

27 Dec '11

Hi, After disabling an output via the kernel command line, e.g. video=VGA-1:d, is there a way to turn it back on again? Harald -- `Experience is the best teacher.'

[ANNOUNCE] intel-gpu-tools 1.1
by Daniel Vetter 24 Dec '11

24 Dec '11

A bit early for a Xmas gift but way too late for a release, I've finally managed to shove out a new intel-gpu-tools version. Too much stuff to list here, and mostly only interesting for developers (who use the latest git version anyway). One thing though I'd like to highlight which is also useful for the wider community of users and testers, is the improved test-suite for the kernel drm: It's just a beginning but after compiling everything you can run (as root, no X running) # make test and watch your kernel die a pityful death. For a less quick death, my next branch at http://cgit.freedesktop.org/~danvet/drm/log/?h=my-next contains fixes for all known issues this hits. Reports for any issues not yet fixed there highly welcome. Enjoy! -Daniel Adam Jackson (6): intel_reg_dumper: Add support for reading register dumps from files bios reader: Decode device type from child device table fix reg_dumper on systems without intel gpus Use longer string padding in intel_reg_dumper on ironlake bios_reader: Fix to work on non-Intel machines bios_reader: Allow forcing the device ID with DEVICE=0xNNNN Ben Widawsky (13): Add MI_SUSPEND_FLUSH instruction decode Add C99 requirement to autoconf. forcewake: Add mmio code to do proper forcewake stuff for gen6 intel-gpu-tools/range handling: register range handling intel-gpu-tools/forcewaked: sample forcewake app intel-gpu-tools/debugging: add important debug regs intel-gpu-tools/debugging: shader debugger tools/range handing: forgot the register map file :( tools: readme addition for shader debugging intel: we don't do distcheck for the debugger i-g-t/debugger: Only allow the shader debugger if the user has specified a gen4asm i-g-t/debugger - make the debugger work with distcheck intel-decode: fix flush dword post sync parse Chris Wilson (112): Add: tools/intel_gpu_time decode: Split decoder and reuse outside of intel_gpu_dump decode/i965: Show byte lengths for buffers. reg: Include INSTPM in dump. gpu_dump: Parse INSTDONE if seen inside a file. intel_gpu_dump: Parse ringbuffer info from i915_error_state Add intel_error_decode. decode: Parse MI_BATCH_BUFFER for i8xx man: Add manpage for intel_error_decode decode: Fix length mask for LOAD_REGISTER_IMM. intel_error_decode: Pretty print i830 PGTBL_ER decode: Parse i915 MAP_STATE texture sizes and tiling decode: There are 4 unpreserved registers on i915, not 3.

[PATCH] drm/i915: Disable semaphores by default on SNB
by Keith Packard 23 Dec '11

23 Dec '11

Semaphores still cause problems on some machines: > From Udo Steinberg: > > With Linux-3.2-rc6 I'm frequently seeing GPU hangs when large amounts of > text scroll in an xterm, such as when extracting a tar archive. Such as this > one (note the timestamps): > > I can reproduce it fairly easily with something > as simple as: > > while true; do dmesg; done This patch turns them off on SNB while leaving them on for IVB.
