It happended when I closed a gwenview window after a few hours of use (window manager was cinnamon). After going black and switching off for a while, the screens (2x DVI and 1x HDMI) came back, but displayed only flickery noise (I could see where the mouse pointer would've been as a differently noisy rectangle, and could move it). I could still ssh into the machine and aquire dmesg and Xorg.0.log. Interesting messages from dmesg: [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting [drm:atom_execute_table_locked] *ERROR* atombios stuck executing C466 (len 254, WS 0, PS 4) @ 0xC490 [drm:atom_execute_table_locked] *ERROR* atombios stuck executing B9EC (len 145, WS 0, PS 8) @ 0xBA77 [drm:ci_dpm_enable] *ERROR* ci_start_dpm failed [drm:radeon_pm_resume_dpm] *ERROR* radeon: dpm resume failed Driver Stack Details: ===================== 1) Kernel: agd5f's drm-next-3.17-wip (2014-08-03), Hawaii accel enabled 2) libdrm: git (2014-08-03) 3) mesa: git (2014-08-03) 4) Xorg-server: 1.16.0 5) xf86-video-ati: git (2014-08-03 with patch to enable accel) 6) glamor: xorg-server integrated 1.0.0 7) llvm: 3.5svn (updated recently) 8) new radeon firmware files for hawaii accel Hardware Configuration: ===================== Graphics Card: Hawaii XT, Sapphire Radeon R9 290X Tri-X OC, 4GB GDDR5 Processor: Core i7-965 (LGA 1366) Mainboard: Asus P6T Deluxe RAM: 6GB -- You are receiving this mail because: You are the assignee for the bug.

[Bug 83331] New: radeon: Laptop panel out of sync after dpms standby/suspend/off
by bugzilla-daemon＠bugzilla.kernel.org 04 Oct '14

04 Oct '14

https://bugzilla.kernel.org/show_bug.cgi?id=83331 Bug ID: 83331 Summary: radeon: Laptop panel out of sync after dpms standby/suspend/off Product: Drivers Version: 2.5 Kernel Version: 3.15.10 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri(a)kernel-bugs.osdl.org Reporter: klaus.kusche(a)computerix.info Regression: No I've a problem on my laptop (Dell Precision M6700 with AMD Cap Verde graphics, ChipID = 0x6825) with the radeon driver (radeon-ucode-20140430): Whenever the X server switches to dpms standby, suspend or off state (it does so after 5 minutes when I'm on battery and idle) and then back to dpms on, the internal panel is out of sync: It is completely unreadable, flashes or shows strange moving patterns. External displays are fine. The problem is independent of the radeon powersave mode (profile or dpm). The only way to recover is either to power cycle or to blindly type xrandr --output eDP --off xrandr --output eDP --auto Switching from X to a text (framebuffer) VT does not help: They are also corrupted. When initializing radeon during boot, the kernel log says radeon 0000:01:00.0: Invalid ROM contents Could that be related? Everything else looks fine. When the problem happens, nothing is written to the kernel log. -- You are receiving this mail because: You are watching the assignee of the bug.

[PATCH v6 0/2] ASoC: tda998x: add a codec to the HDMI transmitter
by Jean-Francois Moine 02 Oct '14

02 Oct '14

The NXP TDA998x HDMI transmitter may transmit audio to the HDMI link from 2 different sources, I2S and S/PDIF. This patch set adds an interface between the HDMI transmitter and the HDMI CODEC. The interface is used by the TDA998x driver to update the audio constraints from the display characteristics (EDID) and by the audio subsystem to connect the chosen audio source to the HDMI link. v6: - extend the HDMI CODEC instead of using a specific CODEC v5: - use the TDA998x private data instead of a specific area for the CODEC interface - the CODEC is TDA998x specific (Mark Brown) v4: - remove all the TDA998x specific stuff from the CODEC - move the EDID scan from the CODEC to the TDA998x - move the CODEC to sound/soc (Mark Brown) - update the audio_sample_rate from the EDID (Andrew Jackson) v3: fix bad rate (Andrew Jackson) v2: check double stream start (Mark Brown) Jean-Francois Moine (2): ASoC:codecs: Add a transmitter interface to the HDMI CODEC drm/i2c:tda998x: Use the HDMI audio CODEC .../devicetree/bindings/drm/i2c/tda998x.txt | 18 ++ drivers/gpu/drm/i2c/Kconfig | 1 + drivers/gpu/drm/i2c/tda998x_drv.c | 299 +++++++++++++++++++-- include/sound/hdmi.h | 20 ++ sound/soc/codecs/hdmi.c | 174 +++++++++++- 5 files changed, 488 insertions(+), 24 deletions(-) create mode 100644 include/sound/hdmi.h -- 2.1.1

page allocator bug in 3.16?
by Peter Hurley 01 Oct '14

01 Oct '14

After several days uptime with a 3.16 kernel (generally running Thunderbird, emacs, kernel builds, several Chrome tabs on multiple desktop workspaces) I've been seeing some really extreme slowdowns. Mostly the slowdowns are associated with gpu-related tasks, like opening new emacs windows, switching workspaces, laughing at internet gifs, etc. Because this x86_64 desktop is nouveau-based, I didn't pursue it right away -- 3.15 is the first time suspend has worked reliably. This week I started looking into what the slowdown was and discovered it's happening during dma allocation through swiotlb (the cpus can do intel iommu but I don't use it because it's not the default for most users). I'm still working on a bisection but each step takes 8+ hours to validate and even then I'm no longer sure I still have the 'bad' commit in the bisection. [edit: yup, I started over] I just discovered a smattering of these in my logs and only on 3.16-rc+ kernels: Sep 25 07:57:59 thor kernel: [28786.001300] alloc_contig_range test_pages_isolated(2bf560, 2bf562) failed This dual-Xeon box has 10GB and sysrq Show Memory isn't showing heavy fragmentation [1]. Besides Mel's page allocator changes in 3.16, another suspect commit is: commit b13b1d2d8692b437203de7a404c6b809d2cc4d99 Author: Shaohua Li <shli(a)kernel.org> Date: Tue Apr 8 15:58:09 2014 +0800 x86/mm: In the PTE swapout page reclaim case clear the accessed bit instead of flushing the TLB Specifically, this statement: It could cause incorrect page aging and the (mistaken) reclaim of hot pages, but the chance of that should be relatively low. I'm wondering if this could cause worse-case behavior with TTM? I'm testing a revert of this on mainline 3.16-final now, with no results yet. Thoughts?

[PATCH] drm/i915: don't crash if unable to setup stolen
by Rob Clark 30 Sep '14

30 Sep '14

On this baytrail NUC I would see: *ERROR* conflict detected with stolen region: [0xbb000000 - 0xbf000000] Since stolen region is not setup, dev_priv->mm.stolen would not be initialized, which results that vlv_pctx is not allocated in valleyview_setup_pctx() which results in things going BOOM in valleyview_check_pctx(). Things seem to work out much better if we check for NULL ptr first.
