https://bugs.freedesktop.org/show_bug.cgi?id=100392 Bug ID: 100392 Summary: Applications Requiring 3d accel fail to launch on Wayland after waking from sleep Product: Mesa Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: major Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel(a)lists.freedesktop.org Reporter: vkontogpls(a)gmail.com QA Contact: dri-devel(a)lists.freedesktop.org Created attachment 130456 --> https://bugs.freedesktop.org/attachment.cgi?id=130456&action=edit Minecraft Crash Log Hardware used: Toshiba P50-b-10v with and intel i7 4710hq with hd4600 integrated gpu and an amd r9 m265x( cape verde) dedicated gpu. Software: Fedora 25 with kernel 4.9.14, on a Wayland session with Gnome. All packages are up to date as the time of writing this report. The issue is that after waking from sleep( or whatever Fedora puts your system after closing the lid on the laptop), applications that require 3d accel fail to launch.

However, it does not solve my other problem, which is that sometimes, when turning the monitor on, the display will not wake; it will just display "No Signal". To make it wake up one has to turn the monitor off and on again a few times, unplug the cable, or (more recently; I'm not sure what changed), turn off the monitor, go to a TTY, and turn the monitor back on. I enabled debugging in /sys/module/drm/parameters/debug, and saw some messages like: dp_aux_ch flags not zero: 00000201 Which lead me to create another patch which I will attach in a reply. The patch does help the monitor consistently wake up as it should. Though the radeon_dp_link errors in dmesg still show up. Both of these issues have been touched on in one way or another in the past. The mutex issue in my first patch was discussed here: https://patchwork.kernel.org/patch/6430431/ And doing a web search for AUX_SW_RX_HPD_DISCON (from my second patch) yielded very little useful information except for an attachment to a similar bug from Alex: https://bugs.freedesktop.org/attachment.cgi?id=115885&action=edit I couldn't find any public documentation that describes what those error flags mean. But apparently removing AUX_SW_RX_HPD_DISCON from the set makes my monitor wake up properly. -- You are receiving this mail because: You are the assignee for the bug.

[Bug 100289] 'flip queue failed in radeon_scanout_flip: Invalid argument' error and small frame buffer allocated on turning off and on new monitor

https://bugs.freedesktop.org/show_bug.cgi?id=100289 Bug ID: 100289 Summary: 'flip queue failed in radeon_scanout_flip: Invalid argument' error and small frame buffer allocated on turning off and on new monitor Product: DRI Version: unspecified Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/Radeon Assignee: dri-devel(a)lists.freedesktop.org Reporter: OmegaPhil(a)startmail.com Created attachment 130326 --> https://bugs.freedesktop.org/attachment.cgi?id=130326&action=edit Xorg log I have just bought a 3rd monitor, successfully hooked up via Display Port to the R9 290X (Tahiti XT) card and configured fine as 3 non-mirrored outputs in XFCE4. I found that when I turned it off for ~10 seconds or more, after turning it back on all screens would go black and appear to reinialise. XFCE4 gets confused and clones the primary monitor output to the new 3rd screen, fiddling in the XFCE4 Display program fixes this (after the problem happens it seems to put the primary and new monitor on top of each other...). Looking into Xorg.0.log, when I turn the monitor off for less than 10 seconds, I just get the following event: =============================================================================== [ 512.737] (WW) RADEON(0): flip queue failed in radeon_scanout_flip: Invalid argument =============================================================================== Being off for 10 seconds or more results in: =============================================================================== [ 1891.671] (II) RADEON(0): Allocate new frame buffer 3840x1200 stride 3840 [ 1891.677] (WW) RADEON(0): flip queue failed in radeon_scanout_flip: Device or resource busy [ 1891.678] (WW) RADEON(0): flip queue failed in radeon_scanout_flip: Device or resource busy =============================================================================== It now makes sense why monitor output appears to be mirrored (only 2 unique outputs) - 3840 is 1920*2.

When running any demanding application with DRI_PRIME=1 the card will hang, one example would be running 'DRI_PRIME=1 glmark2 -b texture'. I have noticed that the content of /sys/kernel/debug/dri/1/radeon_pm_info has changed between kernel 4.9 and 4.10 when running glmark2. With 4.9: power level 4 sclk: 75000 mclk: 80000 vddc: 1050 vddci: 0 pcie gen: 2 With 4.10: power level 4 sclk: 87500 mclk: 90000 vddc: 1050 vddci: 0 pcie gen: 2 This led me to revert commit 3a69adfe5617ceba04ad3cff0f9ccad470503fb2 which prevents the card from hanging.

Adding radeon.runpm=0 to my boot cmdline solves the issues as a workaround. With previous ubuntu/kernel versions, the main issue was the freezing which would happen every seven seconds with the corresponding dmesg block. This would continue ad infinitum, although on rare occasions it would stop after many freezes. However with my current kernel this pattern doesn't seem to occur - it freezes a few times before the freezing stops and the freezes do not occur at regular intervals. I'm not sure if this is a graphics or sound issue from the dmesg block. There's also some ACPI errors in the dmesg log so maybe a firmware problem, or faulty hardware? I tried some lower level debugging previously but couldn't conclude anything. Thanks for any assistance. -- You are receiving this mail because: You are the assignee for the bug.

I am running Ubuntu 16.04, with MATE installed later on it, using the latter currently. Beside normal system updates, I am using the Mesa stable ppa. Recently I started using DRI_PRIME=1 in some cases, to make the AMD videocard working. I found that it doesn't always work and the Intel one is used instead, like DRI_PRIME didn't even matter to it. This happens with Unigine Heaven, Steam and even glxinfo. Strangely, glxgears is not affected, it always does what it should be. I cannot reproduce this behaviour, it just happens sometimes. And it seems to solve itself after a reboot. Tell me, what you need to look into it.

https://bugs.freedesktop.org/show_bug.cgi?id=99326 Bug ID: 99326 Summary: Boot problem and White dots/noise/speckling/shimmering/corruption on Radeon HD6320 Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: major Priority: medium Component: DRM/Radeon Assignee: dri-devel(a)lists.freedesktop.org Reporter: mrj(a)advancedcontrols.com.au A default Gnome install of either Fedora 25 or Fedora 24 (latest spin) Workstation, on a machine with a Radeon HD6320 (AMD G-series T56N) graphics chip running 1360x768@60Hz, has a display that most of the time is black on boot (reboot required -- hangs?), but occasionally completes booting with a display that all over shimmers with white noise, as seen in the following video: https://www.youtube.com/watch?v=dHW6kM4koQ0 The problem has been traced to this Linux kernel commit https://github.com/torvalds/linux/commit/ff0bd441bdfbfa09d05fdba9829a0401a4… , made to fix Bug 95206. Xorg logs and xrandr output seem to indicate the the same modeline is selected after this commit is reversed, even though the boot and display problems no longer occur. The equivalent Red Hat bug is https://bugzilla.redhat.com/show_bug.cgi?id=1402293 -- You are receiving this mail because: You are the assignee for the bug.
