[Why] Due to the generic introduction of seamless boot, the display is no longer blanked upon boot. 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. Signed-off-by:

[Why] Many userspace applications (and IGT) seem to expect that most drivers can keep a CRTC active and enabled if there are no primary or overlay planes. 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. Signed-off-by:

[Why] When disabling all the pipes for a CRTC the page-flip interrupt also gets disabled on Raven. 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.

[Why] We only currently drop the vblank reference when the stream is being removed from the context. We should be dropping it whenever we disable interrupts and reaquiring it after we re-enable them. We also never get the extra reference correctly when re-enabling interrupts, since grabbing the reference has the following condition: if (!crtc_state->crc_enabled && enable) drm_crtc_vblank_get(crtc); This means that crc_enabled must be *false* in order to grab the extra reference. [How] Always drop the ref whenever we're disabling interrupts. Only disable CRC capture when the stream is being removed. Always grab the ref by setting dm_new_crtc_state->crc_enabled = false before the call to re-enable CRC capture. Signed-off-by: -

[Why] We can't do cursor programming after the planes have been disabled since there won't be any pipes - leading to lock warnings and the wrong cursor state being left in the registers. When we re-enable the planes after the previous cursor state will also remain if we don't have a cursor plane. [How] If we're disabling the planes then do the cursor programming first. If we're not disabling the planes then do the cursor programming after. Introduce the amdgpu_dm_commit_cursors helper to avoid code duplication for both of these cases. Signed-off-by:

[Why] The vblank and pageflip interrupts should only be enabled for a CRTC that's enabled and has active planes. 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. Signed-off-by:

[Why] As long as we have at least one non-cursor plane enabled on a CRTC then the CRTC itself can remain enabled. 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.

[Why] DM thinks that the update type should be full whenever a stream or plane is added or removed (including recreations).
