Without the lbpc check for zero the backlight still stayed off and could only be activated with the brightness-down key. This revised patch works correctly for me. Thanks! m.

[Bug 26891] Radeon KMS on Macs with EFI boot
by bugzilla-daemon＠freedesktop.org 17 May '11

https://bugs.freedesktop.org/show_bug.cgi?id=26891 --- Comment #6 from Ortwin Glück <odi(a)odi.ch> 2011-05-17 04:14:24 PDT --- Sorry for being slightly off-topic. I was implicitly referring to bug 27314, where I observe the same problem "radeon 0000:01:00.0: Invalid ROM contents" when booting in legacy mode (where we obviously do have a vbios). -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

https://bugs.freedesktop.org/show_bug.cgi?id=26891 --- Comment #5 from shirk(a)bitspin.org 2011-05-17 03:31:16 PDT --- (In reply to comment #4) I assume you're not familiar with mac or didn't read the while bug history. Mac are booted using the EFI runtime one of the successors to BIOS. > What is the real reason that the driver doesn't see the video BIOS? Is it > looking at the wrong address? Is some MMU wrongly setup? I mean the video BIOS > is obviously there, You're wrong here. The bios is there if you boot in 'legacy mode'. Legacy mode means your EFI machine will load and run a (slow) BIOS emulation. > if you can extract it with dd. This exact step happens in legacy mode. If you boot in native EFI you don't have any BIOS at all. > I would rather see the real > bug fixed than have a workaround. As nice as it sounds 'fixing' would imply writing a separate KMS driver which would work entirely without the need to access the BIOS. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

https://bugs.freedesktop.org/show_bug.cgi?id=27314 --- Comment #44 from Ortwin Glück <odi(a)odi.ch> 2011-05-17 02:45:27 PDT --- But I also noticed the line "radeon 0000:01:00.0: Invalid ROM contents" in my dmesg. Although I am not using EFI boot (plain old grub without EFI support), this indicates that the kernel doesn't see a valid video BIOS, right? So I doubt this bug as anything to do with DP link training actually, and bug 26891 is really the cause. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

Following that patch and procedure : https://bugs.freedesktop.org/show_bug.cgi?id=26891 solves the issue. When the mode is set, the screen displays weird stuff for a moment. I'll investigate drm messages to see what happens. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

[Bug 37263] New: [wine] GPU hang in Left 4 Dead

https://bugs.freedesktop.org/show_bug.cgi?id=37263 Summary: [wine] GPU hang in Left 4 Dead Product: Mesa Version: git Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel(a)lists.freedesktop.org ReportedBy: sa(a)whiz.se Created an attachment (id=46776) --> (https://bugs.freedesktop.org/attachment.cgi?id=46776) dmesg output The game Left 4 Dead (running in Wine) is causing a GPU hang every time I try to start a new game. This is probably related to bug 35051 and bug 36421 but I'm filing it just to be sure. dmesg output including the kernel call trace is attached. I also used apitrace, the resulting trace seems to randomly either recreate the hang or segfaulting so I'm not sure how useful it is: http://dl.dropbox.com/u/28577999/l4d.trace.7z System environment: -- system architecture: 32-bit -- Linux distribution: Debian unstable -- GPU: REDWOOD -- Model: XFX Radeon HD 5670 1GB -- Display connector: DVI -- xf86-video-ati: 6.14.1 -- xserver: 1.10.1 -- mesa: git-51095f7 -- drm: 2.4.25 -- kernel: 2.6.39-rc7 -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
