[PATCH] drm/doc: Switch to sphinx/rst fixed-width quoting
by Daniel Vetter 06 Jun '16

06 Jun '16

Just fallout from switching from asciidoc to sphinx/rst. v2: Found more. Also s/\//#/ in the vgpu ascii-art - sphinx treats those as comments and switch to variable-width, which wreaks the layout. v3: Undo some of the hacks, rebasing onto latest version of Jani's series fixed it.

wrong display resolution

Hi all After upgrading my Ubuntu from 10.04 to 14.04 I only see the upper left detail of the whole screen. In the Xorg log file (see attachment) I found that the mode was probed to 1024x768 instead of 640x480. Then I found a suspicious error message from the kernel that could be the cause of the failed mode setting.

[Bug 117171] New: Radeon GPU lockup in X windows after resuming from blank screen
by bugzilla-daemon＠bugzilla.kernel.org 06 Jun '16

https://bugzilla.kernel.org/show_bug.cgi?id=117171 Bug ID: 117171 Summary: Radeon GPU lockup in X windows after resuming from blank screen Product: Drivers Version: 2.5 Kernel Version: 4.6 rc5 from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-rc5 -wily/ 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: erik.brangs(a)gmx.de Regression: No Created attachment 213991 --> https://bugzilla.kernel.org/attachment.cgi?id=213991&action=edit dmesg output acquired from frozen system with GPU lockup I'm using Ubuntu 16.04 with the 4.6 rc5 kernel build from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-rc5-wily/ . AFAIK this is a mainline kernel with an Ubuntu configuration. Sometimes, when I'm using X windows and resuming from a blank screen, X windows freezes: The previous screen content is properly restored but X windows locks up and ceases to process inputs. The system isn't completely frozen, though: I can still SSH into it. In this case, the dmesg log doesn't have any message about the lockup at the end and the of the Xorg log only has entries about mieq overflowing. This behaviour has been present as long as I have actually tried to get some debugging output. At other times, I can still attempt to switch to the terminal. In that case, the system locks up after the X windows screen content has been removed but before the terminal is shown, e.g. the screen content consists of a single colour. In that case, the tail of the dmesg output contained some lines about GPU lockup: [ 9553.364081] radeon 0000:01:00.0: ring 0 stalled for more than 10440msec [ 9553.364093] radeon 0000:01:00.0: GPU lockup (current fence id 0x0000000000009b9e last fence id 0x0000000000009b9f on ring 0) [ 9553.368211] radeon 0000:01:00.0: Saved 215675 dwords of commands on ring 0.

[ 9553.941224] radeon 0000:01:00.0: failed initializing CP (-22). I don't think that this is a regression because I haven seen freezes like this for a long time (since before the 4.x series). The basic problem (i.e. lockup of X windows) hasn't changed in that time. The frequency of occurence and the timing of the lockup seem to vary based on the kernel version. -- You are receiving this mail because: You are watching the assignee of the bug.

[Bug 35457] [rs690m] Graphics corruption with ati x1200
by bugzilla-daemon＠freedesktop.org 06 Jun '16

06 Jun '16

https://bugs.freedesktop.org/show_bug.cgi?id=35457 --- Comment #108 from Micha <m.st(a)mailbox.org> --- Alreay made a report for x.org. Youre right, such a nice chipset/laptop - and every Raspberry Pi for a few dollars has better drivers today. Its a shame...minutes ago I found out that Ubuntu Mate seems to work, too - but not Kodi. Installed it on Ubuntu Mate and the osd while playing a video has the same striped look as the menubar of Ubuntu's Unity-desktop...not sure if it is the same problem but it looks almost the same. Kodi, most games and most distros - there is almost nothing we can do anymore with these laptops until someone repairs the driver. -- You are receiving this mail because: You are the assignee for the bug.

[PATCH v2] drm/imx: use bus_flags for pixel clock polarity
by Philipp Zabel 04 Jun '16

This patch allows panels to set pixel clock and data enable pin polarity other than the default of driving data at the falling pixel clock edge and active high display enable. Signed-off-by: Philipp Zabel <p.zabel(a)pengutronix.de> --- Changes since v1: - Invert polarity - driving pixel data on the falling edge and sampling it at the rising edge is the default. - Rename imx_drm_set_bus_format_pins to imx_drm_set_bus_config as now, additionally to bus format and pins, it also sets polarities. --- drivers/gpu/drm/imx/imx-drm-core.c | 13 ++++++++----- drivers/gpu/drm/imx/imx-drm.h | 7 ++++--- drivers/gpu/drm/imx/imx-tve.c | 6 ++++-- drivers/gpu/drm/imx/ipuv3-crtc.c | 10 +++++++--- drivers/gpu/drm/imx/parallel-display.c | 4 ++-- 5 files changed, 25 insertions(+), 15 deletions(-) diff --git a/drivers/gpu/drm/imx/imx-drm-core.c b/drivers/gpu/drm/imx/imx-drm-core.c index e26dcde..1da77fd 100644 --- a/drivers/gpu/drm/imx/imx-drm-core.c +++ b/drivers/gpu/drm/imx/imx-drm-core.c @@ -96,8 +96,8 @@ static struct imx_drm_crtc *imx_drm_find_crtc(struct drm_crtc *crtc) return NULL;

[Bug 88458] The monitor turns off when playing starcraft 2 in wine
by bugzilla-daemon＠freedesktop.org 04 Jun '16

https://bugs.freedesktop.org/show_bug.cgi?id=88458 --- Comment #8 from Jaakko Niemi <jaakko.niemi(a)iki.fi> --- Definately maybe. I run: apitrace trace wine .wine/drive_c...path to sc.exe With few minutes running the game I get small file called "wine-preloader.trace", which is 270k, so I'm not sure if this is right. These days the game invokes in any case the battle.net.exe application from which game can be started. I'll do some more digging on this, but if anyone knows how to do this right (wine with modern blizzard games..), please let me know. Also let me know if the small trace file is interesting. -- You are receiving this mail because: You are the assignee for the bug.
