[Why] The actual position for the cursor on the screen is essentially: x_out = x - x_plane - x_hotspot y_out = y - y_plane - y_hotspot The register values for cursor position and cursor hotspot need to be greater than zero when programmed, but we also need to subtract off the plane position to display the cursor at the correct position. Since we don't want x or y to be less than zero, we add the plane position as a positive value to x_hotspot or y_hotspot. However, what this doesn't take into account is that the hotspot registers are limited by the maximum cursor size. On DCN10 the cursor hotspot regitsers are masked to 0xFF, so they have a maximum value of 0-255. Values greater this will wrap, causing the cursor to display in the wrong position. In practice this means that for sufficiently large plane positions, the cursor will be drawn twice on the screen, and can cause screen flashes or p-state WARNS depending on what the wrapped value is. So we need a way to remove the value from x_plane and y_plane without exceeding the maximum cursor size. [How] Subtract as much as x_plane/y_plane as possible from x and y and place the remainder in the cursor hotspot register. The value for x_hotspot and y_hotspot can still wrap around but it won't happen in a case where the cursor is actually enabled. The cursor plane needs to intersect at least one pixel of the plane's rectangle to be enabled, so the cursor position + hotspot provided by userspace must always be strictly less than the maximum cursor size for the cursor to actually be enabled.

We want vblank counts and timestamps of flip completion as sent in pageflip completion events to be consistent with the vblank count and timestamp of the vblank of flip completion, like in non VRR mode. In VRR mode, drm_update_vblank_count() - and thereby vblank count and timestamp updates - must be delayed until after the end of front-porch of each vblank, as it is only safe to calculate vblank timestamps outside of the front-porch, when we actually know when the vblank will end or has ended. The function drm_update_vblank_count() which updates timestamps and counts gets called by drm_crtc_accurate_vblank_count() or by drm_crtc_handle_vblank(). Therefore we must make sure that pageflip events for a completed flip are only sent out after drm_crtc_accurate_vblank_count() or drm_crtc_handle_vblank() is executed, after end of front-porch for the vblank of flip completion. Two cases: a) Pageflip irq handler executes inside front-porch: In this case we must defer sending pageflip events until drm_crtc_handle_vblank() executes after end of front-porch, and thereby calculates proper vblank count and timestamp. Iow. the pflip irq handler must just arm a pageflip event to be sent out by drm_crtc_handle_vblank() later on. b) Pageflip irq handler executes after end of front-porch, e.g., after flip completion in back-porch or due to a massively delayed handler invocation into the active scanout of the new frame. In this case we can call drm_crtc_accurate_vblank_count() to safely force calculation of a proper vblank count and timestamp, and must send the pageflip completion event ourselves from the pageflip irq handler. This is the same behaviour as needed for standard fixed refresh rate mode. To decide from within pageflip handler if we are in case a) or b), we check the current scanout position against the boundary of front-porch. In non-VRR mode we just do what we did in the past.

In VRR mode, proper vblank/pageflip timestamps can only be computed after the display scanout position has left front-porch. Therefore delay calls to drm_crtc_handle_vblank(), and thereby calls to drm_update_vblank_count() and pageflip event delivery, to after the end of front-porch when in VRR mode. We add a new vupdate irq, which triggers at the end of the vupdate interval, ie. at the end of vblank, and calls the core vblank handler function. The new irq handler is not executed in standard non-VRR mode, so vblank handling for fixed refresh rate mode is identical to the past implementation. v2: Implement feedback by Nicholas and Paul Menzel.

For throttling to work correctly, we always need a baseline vblank count last_flip_vblank that increments at start of front-porch. This is the case for drm_crtc_vblank_count() in non-VRR mode, where the vblank irq fires at start of front-porch and triggers DRM core vblank handling, but it is no longer the case in VRR mode, where core vblank handling is done later, after end of front-porch. Therefore drm_crtc_vblank_count() is no longer useful for this. We also can't use drm_crtc_accurate_vblank_count(), as that would screw up vblank timestamps in VRR mode when called in front-porch. To solve this, use the cooked hardware vblank counter returned by amdgpu_get_vblank_counter_kms() instead, as that one is cooked to always increment at start of front-porch, independent of when vblank related irq's fire. This patch allows vblank irq handling to happen anywhere within vblank of even after it, without a negative impact on flip throttling, so followup patches can shift the vblank core handling trigger point wherever they need it.

During VRR mode we can not allow vblank irq dis-/enable transitions, as an enable after a disable can happen at an arbitrary time during the video refresh cycle, e.g., with a high likelyhood inside vblank front-porch. An enable during front-porch would cause vblank timestamp updates/calculations which are completely bogus, given the code can't know when the vblank will end as long as we are in front-porch with no page flip completed. Hold a permanent vblank reference on the crtc while in active VRR mode to prevent a vblank disable, and drop the reference again when switching back to fixed refresh rate non-VRR mode. v2: Make sure transition is also handled if vrr is disabled and stream gets disabled in the same atomic commit by moving the call to the transition function outside of plane commit. Suggested by Nicholas. v3: Trivial rebase onto previous patch. Signed-off-by: -

We need the VRR active/inactive state info earlier in the commit sequence, so VRR related setup functions like amdgpu_dm_handle_vrr_transition() know the final VRR state when they need to do their hw setup work. Split update_freesync_state_on_stream() into an early part, that can run at the beginning of commit tail before the vrr transition handling, and a late part that must run after vrr transition handling inside the commit planes code for enabled crtc's.
