From 0ab925d3690614aa44cd29fb84cdcef03eab97dc Mon Sep 17 00:00:00 2001 From: Nicholas Kazlauskas Date: Thu, 21 Mar 2019 11:53:45 -0400 Subject: drm/amd/display: Only allow VRR when vrefresh is within supported range [Why] Black screens or artifacting can occur when enabling FreeSync outside of the supported range of the monitor. This can happen since the supported range isn't always the min/max vrefresh range available for the monitor. [How] There was previously a fix that prevented this from happening in the low range but it didn't cover the upper range. Expand the condition to include both.

(v3) 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.

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.

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.

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.

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.

There was an attempt to guard against this in hubp1_cursor_set_position by checking the src_x_offset and src_y_offset and offseting the cursor hotspot within hubp1_cursor_set_position. However, the cursor position itself is still being programmed incorrectly as a large value. This manifests itself visually as the cursor disappearing or containing strange artifacts near the middle of the screen on raven. [How] Don't subtract the destination rect top left corner from the pos but add it to the hotspot instead. This happens before the pos gets passed into hubp1_cursor_set_position. This achieves the same result but avoids the subtraction wrap around. With this fix the original cursor programming logic can be used again. v2: add hunk that got dropped accidently when this patch was originally committed.

When getting the private object however, the dm_atomic_state - containing the wiped context - is duplicated into the atomic state. This causes DC validation to fail during atomic check, as necessary function pointers in dc_state are now NULL. [How] Recreate the private object's dm_atomic_state->context during resume, restoring any static values such as function pointers. A TODO item is added to move static read-only values out of dc_state - they shouldn't be there anyways.

If we need to add or force reset any plane in the context then we'll need to do the same for every plane on the stream.

There are some medium and full updates that can cause bandwidth or clock changes to occur resulting in underflow or corruption. We need to be able to fill surface and plane info updates during atomic commit for dm_determine_update_type for commit. Since we already do this during atomic commit tail it would be good if we had the same logic in both places for creating these structures. [How] Introduce fill_dc_scaling_info and fill_dc_plane_info_and_addr. These two functions cover the following three update structures: - struct dc_scaling_info - struct dc_plane_info - struct dc_plane_address Cleanup and adapter the existing fill_plane_* helpers to work with these functions. Update call sites that used most of these sub helpers directly to work with the new functions. The exception being prepare_fb - we just want the new buffer attributes specifically in the case where we're creating the plane. This is needed for dc_commit_state in the case where the FB hasn't been previously been used. This isn't quite a refactor, but functionally driver behavior should be mostly the smae as before. The one exception is that we now check the return code for fill_plane_buffer_attributes which means that commits will be rejected that try to enable DCC with erroneous parameters.

We should fail atomic check validation if we aren't capable of doing the scaling. [How] We don't currently create store which DC plane maps to which DRM plane so we can't easily check the caps directly. For now add basic constraints that cover the absolute min and max downscale / upscale limits for most RGB and YUV formats across ASICs. Leave a TODO indicating that these should really be done with DC caps. We'll probably need to subclass DRM planes again in order to correctly identify which DC plane maps to it.

This doesn't give us much improvement yet, since we always create a new dc_plane_state when state->allow_modeset is true. The call into dc_check_update_surfaces_for_stream also needs to be locked, for two reasons: 1. It checks the current DC state 2.

This will allow for commits where there's an overlay plane enabled but no primary plane enabled. [How] Remove existing primary plane fb != NULL checks and replace them with the new does_crtc_have_active_plane helper. This will be called from atomic check when validating the CRTC. Since the primary plane state can now potentially be NULL we'll need to guard for that when accessing it in some of the cursor logic.

The current logic takes care of this, but isn't setup to handle the case where the active plane count goes to zero but the stream remains enabled. We currently block this case since we don't allow commits that enable a CRTC with no active planes, but shouldn't be any reason we can't support this from a hardware perspective and many userspace applications expect to be able to do it (like IGT). [How] The count_crtc_active_planes function fills in the number of "active_planes" on the dm_crtc_state. This should be the same as DC's plane_count on the stream_status but easier to access since we don't need to lock the private atomic state with the DC context. Add the "interrupts_enabled" flag to the dm_crtc_state and set it based on whether the stream exists and if there are active planes on the stream. Update the disable and enable logic to make use of this new flag. There shouldn't be any functional change (yet) with this patch.

We can't re-enable the page-flip interrupt unless we give DC at least one active DC plane. We currently enable interrupts after the call to dc_commit_state since there's currently no valid sequence that should disable all the planes or re-enable planes for a CRTC without first going through dc_commit_state. If we were to allow for a CRTC to be enabled with no primary plane this would not be the case - the call to dc_commit_updates_for_stream would enable the planes when going from zero to at least one active plane, but manage_dm_interrupts would have been called too early. This results in a page-flip timeout on any subsequent commits since we think the page-flip are now enabled when they're actually disabled. We need to enable interrupts after the call to dc_commit_updates_for_stream. [How] Split enabling interrupts into two passes. One pass before dc_commit_updates_for_stream and one after it. Shifting all the interrupts to be strictly below the call doesn't currently work even though it should in theory. We end up queuing off the vblank event to be handle by the flip handler before it's actually enabled in some cases, particularly: old_crtc_state->active = false -> new_crtc_state->active = true The framebuffer states haven't changed and we can technically still do a "pageflip" in this case and send back the event.

DC is setup to handle this but only in the case where there are absolutely no planes on the CRTC - no primary, cursor, or overlay. [How] Add a check to reject commits that have cursor planes enabled and nothing else on CRTCs since we can't handle that. The new helper does_crtc_have_active_cursor is used for this. In atomic commit tail, we need to let DC know that there are zero planes enabled when doing stream updates to let it disable and blank pipes as appropriate.

However, this causes corruption on some systems that does not lock the memory in the non-secure boot case, resulting in brief corruption on boot due to garbage being written into the frame buffer. [How] Add a flag, read during DC init, to determine whether display should be blanked on boot. Default to true.

After the interrupt toggling logic was moved around for support enabling CRTCs with no primary planes active this was no longer being called in the case where there wasn't a modeset. This fixes failures in igt@kms_vrr@* with error "Timed out: Waiting for vblank event". [How] Shift them back into the loop that always ran before interrupts were enabled. Pull out the logic that updated VRR state into the same loop since there's no reason these need to be split. In the case where we're going from VRR off, no planes to VRR on, some active planes we'll still be covered for having the VRR vupdate handler enabled - vblank will be re-enabled at this point, it will see that VRR is active and set the vupdate interrupt on there.

(v3) Pre-DCE12 needs special treatment for BTR / low framerate compensation for more stable behaviour: According to comments in the code and some testing on DCE-8 and DCE-11, DCE-11 and earlier only apply VTOTAL_MIN/MAX programming with a lag of one frame, so the special BTR hw programming for intermediate fixed duration frames must be done inside the current frame at flip submission in atomic commit tail, ie. one vblank earlier, and the fixed refresh intermediate frame mode must be also terminated one vblank earlier on pre-DCE12 display engines. To achieve proper termination on < DCE-12 shift the point when the switch-back from fixed vblank duration to variable vblank duration happens from the start of VBLANK (vblank irq, as done on DCE-12+) to back-porch or end of VBLANK (handled by vupdate irq handler). We must leave the switch-back code inside VBLANK irq for DCE12+, as before. Doing this, we get much better behaviour of BTR for up-sweeps, ie. going from short to long frame durations (~high to low fps) and for constant framerate flips, as tested on DCE-8 and DCE-11. Behaviour is still not quite as good as on DCN-1 though. On down-sweeps, going from long to short frame durations (low fps to high fps) < DCE-12 is a little bit improved, although by far not as much as for up-sweeps and constant fps. v2: Fix some wrong locking, as pointed out by Nicholas. v3: Simplify if-condition in vupdate-irq - nit by Nicholas.
