2020-04-07drm/amd/display: Acknowledge wm_optimized_requiredJoshua Aberback
[Why] If dc->clk_mgr->funcs->are_clock_states_equal is set, then wm_optimized_required is never checked. In that case, when going from a higher mode to a lower mode, wm_optimized_required remains true until the next mode change.

2020-04-07drm/amd/display: Make cursor source translation adjustment optionalNicholas Kazlauskas
[Why] In some usecases, like tiled display, the stream and plane configuration can be setup in a way where the caller expects DAL to perform the clipping, eg: P0: src_rect(0, 0, w, h) dst_rect(0, 0, w, h) P1: src_rect(w, 0, w, h) dst_rect(0, 0, w, h) Cursor is enabled on both streams with the same position. This can result in double cursor on tiled display, even though this behavior is technically correct from the DC interface point of view. We need a mechanism to control this dynamically. [How] This is something that should live in the DM layer based on detection of the specified configuration but it's not something that we really have enough information to deal with today. Add a flag to the cursor position state that specifies whether we want DC to do the translation or not and make it opt-in and let the DM decide when to do it.

2020-04-07drm/amd/display: Calculate scaling ratios on every medium/full updateNicholas Kazlauskas
[Why] If a plane isn't being actively enabled or disabled then DC won't always recalculate scaling rects and ratios for the primary plane. This results in only a partial or corrupted rect being displayed on the screen instead of scaling to fit the screen. [How] Add back the logic to recalculate the scaling rects into dc_commit_updates_for_stream since this is the expected place to do it in DC. This was previously removed a few years ago to fix an underscan issue but underscan is still functional now with this change - and it should be, since this is only updating to the latest plane state getting passed in.

We're missing the check for the position update bit that was there in the DCN10 hardware sequencer. [How] Check the position bit along with the scaling bit like we were doing with DCN20.

2020-04-07drm/amd/display: Fix incorrect cursor pos on scaled primary planeNicholas Kazlauskas
[Why] Cursor pos is correctly adjusted from DC side for source rect offset on DCN ASIC, but only on the overlay. This is because DM places offsets the cursor for primary planes only to workaround missing code in DCE for the adjustment we're now correctly doing in DC for DCN ASIC.

2020-04-07drm/amd/display: Translate cursor position by source rectNicholas Kazlauskas
[Why] Cursor is drawn as part of the framebuffer for a plane on AMD hardware. The cursor position on the framebuffer does not change even if the source rect viewport for the cursor does. This causes the cursor to be clipped. The following IGT tests fail as a result of this issue: - kms_plane_cursor@pipe-*-viewport-size-* [How] Offset cursor position by plane source rect viewport. If the viewport is unscaled then the cursor is now correctly positioned on any plane - primary or overlay.

If start is greater than or equal to svmm->unmanaged.limit, then limit will also be greater than svmm->unmanaged.limit which is greater than svmm->unmanaged.start and the start = max_t(u64, start, svmm->unmanaged.limit) will change nothing.

The calculation for the intersecting range in nouveau_svmm_bind() isn't accounting for this and can call migrate_vma_setup() with a starting address less than vma->vm_start.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: "New tracing features: - The ring buffer is no longer disabled when reading the trace file. The trace_pipe file was made to be used for live tracing and reading as it acted like the normal producer/consumer. As the trace file would not consume the data, the easy way of handling it was to just disable writes to the ring buffer. This came to a surprise to the BPF folks who complained about lost events due to reading. This is no longer an issue. If someone wants to keep the old disabling there's a new option "pause-on-trace" that can be set. - New set_ftrace_notrace_pid file. PIDs in this file will not be traced by the function tracer. Similar to set_ftrace_pid, which makes the function tracer only trace those tasks with PIDs in the file, the set_ftrace_notrace_pid does the reverse. - New set_event_notrace_pid file. PIDs in this file will cause events not to be traced if triggered by a task with a matching PID. Similar to the set_event_pid file but will not be traced. Note, sched_waking and sched_switch events may still be traced if one of the tasks referenced by those events contains a PID that is allowed to be traced. Tracing related features: - New bootconfig option, that is attached to the initrd file.

2020-04-05drm/prime: fix extracting of the DMA addresses from a scatterlistMarek Szyprowski
Scatterlist elements contains both pages and DMA addresses, but one should not assume 1:1 relation between them. The sg->length is the size of the physical memory chunk described by the sg->page, while sg_dma_len(sg) is the size of the DMA (IO virtual) chunk described by the sg_dma_address(sg). The proper way of extracting both: pages and DMA addresses of the whole buffer described by a scatterlist it to iterate independently over the sg->pages/sg->length and sg_dma_address(sg)/sg_dma_len(sg) entries.

2020-04-03drm/amd/amdgpu_dm/mst: Remove ->destroy_connector() callbackLyude Paul
Pankaj Bharadiya started cleaning up the MST connector callbacks a while ago, as I pointed out that they are the same across every driver and don't serve much purpose. There was one callback that was left over though from amdgpu, that we delayed removing due to not being completely sure as to whether or not it was needed. So, I've read through said callback and can confirm it's not at all needed. Pretty much all of the work that is done in dm_dp_destroy_mst_connector() can be done in dm_dp_mst_connector_destroy(). Additionally, I've removed some bits that didn't actually do anything: * Removed DRM_INFO message we were printing, this shouldn't be info level and there's more appropriate drm debugging flags that should be used instead * Removed amdgpu_dm_update_freesync_caps() - reading into this function, it doesn't actually do anything important and I'm not sure why it was ever being called here * Stop clearing aconnector->dc_sink - this also doesn't do anything * Stop clearing link settings in dc_link - this also doesn't do anything * Also, use shorter variable Signed-off-by: Lyude Paul <lyude@redhat.com> Cc: Pankaj Bharadiya <pankaj.laxminarayan.bharadiya@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200331205740.135525-3-lyude@redhat.com Reviewed-by: Alex Deucher <alexdeucher@gmail.com>
