If I enable layers.acceleration.force-enabled in Firefox nightly, Firefox always hangs after a little while of browsing. This is a regression somewhere, this worked during a couple of months... -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.freedesktop.org/show_bug.cgi?id=92996 Bug ID: 92996 Summary: [Fiji/amdgpu/Powerplay] Problems with vsync, interactivity, performance, EQ overflow with Powerplay Product: DRI Version: XOrg git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel(a)lists.freedesktop.org Reporter: ernstp(a)gmail.com Not sure if all these problems are related or not, I think they are. This happens when I test Powerplay with my Fiji. When I start the Steam client the mouse cursor freezes a number of times for a short duration. Also interactivity during 3D graphics is bad.

Useful apitrace from 18 WoS: Pedal to the Metal game - it is OpenGL game running under wine: https://dl.dropboxusercontent.com/u/74553632/pttm_trace2.7z The same issue i found that can be reproduced is with 3DMark2001 http://www.futuremark.com/benchmarks/legacy (which is mostly for benchmarking DirectX8 features.

[PATCH RFC 0/4] Linking DRM Connectors to Backlight Devices
by David Herrmann 24 Oct '16

24 Oct '16

Hi This series introduces a link between DRM connectors and backlight-class devices. It tries to solve some long standing issues: * User-space currently has a hard-time figuring out which backlight device to use, and which backlight device belongs to which display. So far, most systems only provide backlight-devices for internal displays, so figuring out the connection is easy, but that might change with more capable external connectors. If multiple backlights are available, the easiest solution is to simply write to all of them and hope at least one of them works. This obviously fails if the devices interact badly, so it's not really a solution. * User-space needs root privileges to write to sysfs. There are no char-devs that can be used to control access-management to the backlight API, so /sys is the only interface available. So far, udev policy has been "/sys is read-only for non-root" and it's not going to change. char-devs are *THE* standard way to provide non-root user-space APIs, so use them! Several solutions have been discussed so far, but we never agreed on one. I'm aware of at least the following solutions: * Provide char-devs for backlight devices and a sysfs link from connectors to backlight devices. This way, user-space can managed access to char-devs *and* get proper topology information. However, this might be an n:m relationship (n:1 for displays exposed as multiple connectors, 1:m for boards with multiple backlights? whatever..) and it sounds like a waste of resources to add char-devs just to write brightness values. * Do everything in privileged user-space. One daemon that provides an unprivileged-API and forwards writes to /sys. It reads topology information from udev hwdb. This circumvents the ugly sysfs API and not really solves the problem. It should work, though ugly. * Add a DRM connector property that takes brightness values. This is the nicest solution for user-space, but introduces a whole lot of issues on the kernel side. There already is a backlight-class and we had a hard-time trying to move it into DRM drivers, so no-one ever did the work. This series tries to solve this problem with a much simpler approach: Instead of moving backlights into DRM, we simply link DRM properties to a backlight device. That is, the kernel manages a link between a connector and a backlight device (or n backlight devices) which can be modified by udev in case the kernel got it wrong (we don't want huge board-fixup-tables in the kernel). User-space can now use the simpl DRM API to manage backlights, and the kernel does not need any special driver code to make it work. Patch #1 and #2 are cleanups and can be applied right away. #3 adds in-kernel backlight APIs and #4 implements the connector-backlight link. Comments welcome!
