* drm/amd/display: Only get the connector state for VRR when toggledNicholas Kazlauskas2019-01-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | [Why] This fixes a stuttering issue that occurs when moving a hardware cursor when VRR is enabled. Previously when VRR is enabled atomic check will grab the connector state for every atomic update. This has to lock the connector in order to do so. The locking is bad enough by itself for performance, but it gets worse with what we do just below that - add all the planes for the CRTC to the commit. This prevents the cursor fast path from working - there's more than one plane now. With state->allow_modeset = true on top of this, it also adds and removes all the planes from the DC context triggering a full (very slow) update in DC. [How] We need the connector state to get the VRR min/max capbilities, but we only need them when there's a CRTC mode change or when VRR is toggled. The condition has been updated accordingly.

| * | drm/fb-helper: Ignore the value of fb_var_screeninfo.pixclockIvan Mironov2019-01-101-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Strict requirement of pixclock to be zero breaks support of SDL 1.2 which contains hardcoded table of supported video modes with non-zero pixclock values[1]. To better understand which pixclock values are considered valid and how driver should handle these values, I briefly examined few existing fbdev drivers and documentation in Documentation/fb/. And it looks like there are no strict rules on that and actual behaviour varies: * some drivers treat (pixclock == 0) as "use defaults" (uvesafb.c); * some treat (pixclock == 0) as invalid value which leads to -EINVAL (clps711x-fb.c); * some pass converted pixclock value to hardware (uvesafb.c); * some are trying to find nearest value from predefined table (vga16fb.c, video_gx.c). Given this, I believe that it should be safe to just ignore this value if changing is not supported. It seems that any portable fbdev application which was not written only for one specific device working under one specific kernel version should not rely on any particular behaviour of pixclock anyway. However, while enabling SDL1 applications to work out of the box when there is no /etc/fb.modes with valid settings, this change affects the video mode choosing logic in SDL. Depending on current screen resolution, contents of /etc/fb.modes and resolution requested by application, this may lead to user-visible difference (not always): image will be displayed in a right way, but it will be aligned to the left instead of center. There is no "right behaviour" here as well, as emulated fbdev, opposing to old fbdev drivers, simply ignores any requsts of video mode changes with resolutions smaller than current. The easiest way to reproduce this problem is to install sdl-sopwith[2], remove /etc/fb.modes file if it exists, and then try to run sopwith from console without X. At least in Fedora 29, sopwith may be simply installed from standard repositories.

| * | drm/fb-helper: Partially bring back workaround for bugs of SDL 1.2Ivan Mironov2019-01-101-53/+73

Prior to commit db05c48197759 ("drm: fb-helper: Reject all pixel format changing requests"), there was an unintentional workaround for this that existed for more than a decade. First in device-specific DRM drivers, then here in drm_fb_helper.c. Previous code containing this workaround just ignores pixel format fields from userspace code. Not a good thing either, as this way, driver may silently use pixel format different from what client actually requested, and this in turn will lead to displaying garbage on the screen. I think that returning EINVAL to userspace in this particular case is the right option, so I decided to left code from problematic commit untouched instead of just reverting it entirely. Here is the steps required to reproduce this problem exactly: 1) Compile fceux[2] with SDL 1.2.15 and without GTK or OpenGL support. SDL should be compiled with fbdev support (which is on by default). 2) Create /etc/fb.modes with following contents (values seems not used, and just required to trigger problematic code in SDL): mode "test" geometry 1 1 1 1 1 timings 1 1 1 1 1 1 1 endmode 3) Create ~/.fceux/fceux.cfg with following contents: SDL.Hotkeys.Quit = 27 SDL.DoubleBuffering = 1 4) Ensure that screen resolution is at least 1280x960 (e.g. append "video=Virtual-1:1280x960-32" to the kernel cmdline for qemu/QXL). 5) Try to run fceux on VT with some ROM file[3]: # ./fceux color_test.nes [1] SDL 1.2.15 source code, src/video/fbcon/SDL_fbvideo.c, FB_SetVideoMode() [2] http://www.fceux.com [3] Example ROM: https://github.com/bokuweb/rustynes/blob/master/roms/color_test.nes Reported-by: saahriktu <mail@saahriktu.org> Suggested-by: saahriktu <mail@saahriktu.org> Cc: stable@vger.kernel.org Fixes: db05c48197759 ("drm: fb-helper: Reject all pixel format changing requests") Signed-off-by: Ivan Mironov <mironov.ivan@gmail.com> [danvet: Delete misleading comment.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20190108072353.28078-2-mironov.ivan@gmail.com Link: https://patchwork.freedesktop.org/patch/msgid/20190108072353.28078-2-mironov.ivan@gmail.com

| * | | drm/amdgpu: Don't fail resume process if resuming atomic state failsLyude Paul2019-01-081-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an ugly one unfortunately. Currently, all DRM drivers supporting atomic modesetting will save the state that userspace had set before suspending, then attempt to restore that state on resume. This probably worked very well at one point, like many other things, until DP MST came into the picture. While it's easy to restore state on normal display connectors that were disconnected during suspend regardless of their state post-resume, this can't really be done with MST because of the fact that setting up a downstream sink requires performing sideband transactions between the source and the MST hub, sending out the ACT packets, etc. Because of this, there isn't really a guarantee that we can restore the atomic state we had before suspend once we've resumed. This sucks pretty bad, but so far I haven't run into any compositors that this actually causes serious issues with. Most compositors will notice the hotplug we send afterwards, and then reprobe state. Since nouveau and i915 also don't fail the suspend/resume process due to failing to restore the atomic state, let's make amdgpu match this behavior. Better to resume the GPU properly, then to stop the process half way because of a potentially unavoidable atomic commit failure. Eventually, we'll have a real fix for this problem on the DRM level. But we've got some more important low-hanging fruit to deal with first.

Currently, amdgpu just makes the mistake of ignoring the return code from drm_dp_mst_topology_mgr_resume() which means that if a topology was removed in suspend, amdgpu never notices and assumes it's still connected which leads to all sorts of problems. So, fix this by actually checking the rc from drm_dp_mst_topology_mgr_resume(). Also, reformat the rest of the function while we're at it to fix the over-indenting.
