I've played around with dummy-irq on my own gm45 and afaict every gmbus interrupt generates both an msi and a legacy pci interrupt when msi is enabled. Everything else (= other interrupt sources) seems to work as expected, and disabling msi also papers over the issue. There's also scary comments in our gm45 irq handler that we need msi to paper over some other races. So I've decided that I don't want to dwell any longer in this particular dungeon and that your bandaid (of just disabling this mess) is the real fix.

linux-next: manual merge of the drm-intel tree with Linus' tree
Hi all,
Today's linux-next merge of the drm-intel tree got a conflict in
drivers/gpu/drm/i915/intel_dp.c between commit 9d1a455b0ca1 ("") from
Linus' tree and commit 965e0c489f36 ("drm/i915: introduce
pipe_config->dither|pipe_bpp") from the drm-intel tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).

[Bug 61182] r600g causes KWin crashes with kernel 3.8
https://bugs.freedesktop.org/show_bug.cgi?id=61182 --- Comment #21 from korg...@yandex.com --- I can also confirm this bug. Software: Archlinux standard installation. Linux 3.8.4-1-ARCH #1 SMP PREEMPT Wed Mar 20 22:10:25 CET 2013 x86_64 GNU/Linux KDE: 4.10.1 (no widgets, other than the task panel) Kwin: 4.10.1 (standard OpenGL effects installed) Org X Server 1.14.0 Release Date: 2013-03-05 X Protocol Version 11, Revision 0 Build Operating System: Linux 3.8.2-1-ARCH x86_64 Kernel command line: BOOT_IMAGE=/boot/vmlinuz-linux root=UUID=xyz ro init=/usr/lib/systemd/systemd Build Date: 09 March 2013 11:43:05AM Current version of pixman: 0.28.2 mesa: 9.1.1-1 (standard Arch package) I also tried a git version from AUR repository (same crashes): OpenGL vendor string: X.Org OpenGL renderer string: Gallium 0.4 on AMD RV770 OpenGL version string: 3.0 Mesa 9.2.0 (git-135bb3c) OpenGL shading language version string: 1.30 Driver: R600G GPU class: R700 OpenGL version: 3.0 GLSL version: 1.30 Mesa version: 9.2 X server version: 1.14 Linux kernel version: 3.8.4 Direct rendering: yes Requires strict binding:no GLSL shaders: yes Texture NPOT support: yes Virtual Machine:no Application::crashHandler() called with signal 7; recent crashes: 1 Xorg.conf: empty Hardware: Intel i7 920 ATI RV790 [Radeon HD 4890] 1GB VRAM Monitor 1: 1920x1200 (DVI) - image as background Monitor 2: 1920x1080 (HDMI) - image as background Two virtual desktops configured. How to reproduce: just log in into KDM. When the standard KDE desktop is displayed the first Kwin crash (caused by r600 crash) has occurred and its errors is already being displayed. Kwin is re-spawned and everything seems to be normal for some minutes. Then it crashes again and then again, and again until kwin and the desktop are dead definitively. It doesn't seem to matter what applications are being used or if the second monitor is on or off. The crashes happens all the same. I didn't try to downgrade either the kernel or xorg, but I'm sure those crashes started to happen after the latest kernel upgrade to 3.8.x.

Sorry but your log doesn't say what you are doing. You are just adding
relevant calls to clk_prepare/unprepare() before calling clk_enable/disable.

You are doing things at the right place but i have a suggestion. Are you doing
anything in your clk_prepare() atleast for this device? Probably not.
If not, then its better to call clk_prepare/unprepare only once at probe/remove
and keep clk_enable/disable calls as is.

[PATCH v3] drm/exynos: enable FIMD clocks
While migrating to common clock framework (CCF), found that the FIMD clocks
were pulled down by the CCF.
If CCF finds any clock(s) which has NOT been claimed by any of the
drivers, then such clock(s) are PULLed low by CCF.
By calling clk_prepare_enable() for FIMD clocks fixes the issue.
this patch also replaces clk_disable() with clk_disable_unprepare()
during exit.

Changes since v2:
- moved clk_prepare_enable() and clk_disable_unprepare() from
fimd_probe() to fimd_clock() as suggested by Inki Dae
Changes since v1:
- added error checking for clk_prepare_enable() and also replaced
clk_disable() with clk_disable_unprepare() during exit.

I've played around with dummy-irq on my own gm45 and afaict every gmbus interrupt generates both an msi and a legacy pci interrupt when msi is enabled. Everything else (= other interrupt sources) seems to work as expected, and disabling msi also papers over the issue. There's also scary comments in our gm45 irq handler that we need msi to paper over some other races. So I've decided that I don't want to dwell any longer in this particular dungeon and that your bandaid (of just disabling this mess) is the real fix.

fwiw, tilcdc drm driver won't set clocks until you do modeset, as it
is setting them based on the requested pixel clock. As opposed to
setting it once at boot time.
Michal, you may want to add 'drm.debug=7' in your bootargs, and send
the bootlog. That should set some light about whether it is even
trying to modeset but failing, or some other issue.

Not sure about the LCDC DRM driver, but I just tested clk_set_rate()
For lcdc_gclk clock and it is working for me. I could able to set
300MHz freq on my BeagleBone platform, with below code -

Sorry but your log doesn't say what you are doing. You are just adding
relevant calls to clk_prepare/unprepare() before calling clk_enable/disable.

You are doing things at the right place but i have a suggestion. Are you doing
anything in your clk_prepare() atleast for this device? Probably not.
If not, then its better to call clk_prepare/unprepare only once at probe/remove
and keep clk_enable/disable calls as is.

[PATCH v3] drm/exynos: enable FIMD clocks
While migrating to common clock framework (CCF), found that the FIMD clocks
were pulled down by the CCF.
If CCF finds any clock(s) which has NOT been claimed by any of the
drivers, then such clock(s) are PULLed low by CCF.
By calling clk_prepare_enable() for FIMD clocks fixes the issue.
this patch also replaces clk_disable() with clk_disable_unprepare()
during exit.

Changes since v2:
- moved clk_prepare_enable() and clk_disable_unprepare() from
fimd_probe() to fimd_clock() as suggested by Inki Dae
Changes since v1:
- added error checking for clk_prepare_enable() and also replaced
clk_disable() with clk_disable_unprepare() during exit.

fwiw, tilcdc drm driver won't set clocks until you do modeset, as it
is setting them based on the requested pixel clock. As opposed to
setting it once at boot time.
Michal, you may want to add 'drm.debug=7' in your bootargs, and send
the bootlog. That should set some light about whether it is even
trying to modeset but failing, or some other issue.

[Bug 45641] Screen goes black randomly
https://bugs.freedesktop.org/show_bug.cgi?id=45641 --- Comment #18 from John --- I tried the patch today but got another black screen already.

[Bug 56041] New: Disabling LCD on ARUBA causes hotplug loop
https://bugzilla.kernel.org/show_bug.cgi?id=56041 Summary: Disabling LCD on ARUBA causes hotplug loop Product: Drivers Version: 2.5 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri at kernel-bugs.osdl.org ReportedBy: darktjm at gmail.com Regression: No My hardware: a Gateway/Acer laptop with Radeon HD 7640G. Disabling the LCD (xrandr --output eDP --off) while the external display is being used causes some sort of hotplug event loop. 100% of one CPU's worth of CPU time is consumed, and X freezes every few seconds. For now, I have worked around by commenting out "queue_hotplug = true" in evergreen.c (case 0). -- 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 56031] New: Enabling radeon HDMI audio causes video corruption in unsupported hardware
https://bugzilla.kernel.org/show_bug.cgi?id=56031 Summary: Enabling radeon HDMI audio causes video corruption in unsupported hardware Product: Drivers Version: 2.5 Kernel Version: 3.8 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: low Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri at kernel-bugs.osdl.org ReportedBy: darktjm at gmail.com Regression: Yes I changed laptops from an r600 to an aruba, and accidentally left radeon.audio=1 in my kernel parameters. This caused the external screen to be shifted right a bit and a pink stripe on the left. This is due to change f92e70cae880e3540d0c1dddc64825b70f963703 which does not filter out DCE6 (since it is currently unsupported for HDMI) as it should. The patch I have attached adds this restriction, but it might be better if somewhere early in the device initialization radeon_audio were just set to 0 if unsupported. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug.
