https://bugzilla.kernel.org/show_bug.cgi?id=38622 Summary: [radeon cayman regresion] artefacts on screen Product: Drivers Version: 2.5 Kernel Version: 3.0.0-rc3 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri(a)kernel-bugs.osdl.org ReportedBy: kernellist(a)neutrinus.com Regression: Yes When running kernel versions => 3.0.0-rc3 there are a lot of artifacts on screen when runing xorg. Kernel 3.0.0-rc2 and olders were producing clean image, right now there are artifacts on screen, making any fonts/graphics unreadable. 3.0.0-rc[3-5] are affected. It fully reproducible: just run kde :) Its happends everytime when I switch 3.0.0-rc2 kernel to something newer. I'm using debian AMD64 sid+experimental, kernel images from experimental. I'm using xorg "radeon" driver. Mesa: 7.11~0-2. There are no Ops, no strange logs in dmesg...

There are no problems when the X server is not launched, but when it starts (with KDM) something bad soon happens. If I don't login into KDM, it may freeze after few minutes. If I login, an oops happen after few minutes. Unfortunately I can't tell exactly when this behavior started to happen, but somewhere between 2.6.39 and 2.6.39.1. Yesterday I compiled the kernel from git but no luck. I tried to disable pageflipping (as suggested in bug #32402) but the oops happened again. WIth pageflipping disabled, I managed to ssh into the machine and get dmesg and Xorg.log (attached). Unfortunately, I didn't manage to ssh into the machine with pageflipping enabled. I have a Radeon X300 card and I am using mesa git from 20110616, libdrm 2.4.25 and Xorg 1.10.2. If I need to test anything, please let me know, thanks. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.

[Bug 37502] New: Kernels oops display in X leaves screen garbled
by bugzilla-daemon＠bugzilla.kernel.org 24 Aug '12

Switching to a virtual console, and back to X (twice) restored my desktop. I don't know if the kernel is trying to switch to a text console to display the Oops, or if it tries to display the oops on the graphical console, but apparently its not working well. The first time I get an Oops after a reboot I get to see the Oops text on a black background (and my mouse cursor, which makes me believe this is the graphical KMS console), but everything after that just leaves me with a garbled screen. The oops displayed is: https://lkml.org/lkml/2011/6/15/50 I don't know if this is a regression or not, I rarely get Oopses, and last time I got a panic message I was able to see it (although I was in X at the time), but then so can I for the 1st Oops message. My graphics card is: 01:00.0 VGA compatible controller: ATI Technologies Inc RV730 PRO [Radeon HD 4650] I use KMS, Xorg 1.10.2, and Mesa 7.10.2-3. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.

[PATCH] drm/radeon: add proper checking of RESOLVE_BOX command for r600-r700
by Marek Olšák 24 Aug '12

24 Aug '12

Checking of the second colorbuffer was skipped on r700, because CB_TARGET_MASK was 0xf. With r600, CB_TARGET_MASK is changed to 0xff, so we must set the number of samples of the second colorbuffer to 1 in order to pass the CS checker. The DRM version is bumped, because RESOLVE_BOX is always rejected without this fix on r600.
