2019-02-27drm/amd/display: Use vrr friendly pageflip throttling in DC.Mario Kleiner1-0/+1
In VRR mode, keep track of the vblank count of the last completed pageflip in amdgpu_crtc->last_flip_vblank, as recorded in the pageflip completion handler after each completed flip. Use that count to prevent mmio programming a new pageflip within the same vblank in which the last pageflip completed, iow. to throttle pageflips to at most one flip per video frame, while at the same time allowing to request a flip not only before start of vblank, but also anywhere within vblank. The old logic did the same, and made sense for regular fixed refresh rate flipping, but in vrr mode it prevents requesting a flip anywhere inside the possibly huge vblank, thereby reducing framerate in vrr mode instead of improving it, by delaying a slightly delayed flip requests up to a maximum vblank duration + 1 scanout duration. This would limit VRR usefulness to only help applications with a very high GPU demand, which can submit the flip request before start of vblank, but then have to wait long for fences to complete. With this method a flip can be both requested and - after fences have completed - executed, ie. it doesn't matter if the request (amdgpu_dm_do_flip()) gets delayed until deep into the extended vblank due to cpu execution delays. This also allows clients which want to regulate framerate within the vrr range a much more fine-grained control of flip timing, a feature that might be useful for video playback, and is very useful for neuroscience/vision research applications. In regular non-VRR mode, retain the old flip submission behavior. This to keep flip scheduling for fullscreen X11/GLX OpenGL clients intact, if they use the GLX_OML_sync_control extensions glXSwapBufferMscOML(, ..., target_msc,...) function with a specific target_msc target vblank count. glXSwapBuffersMscOML() or DRI3/Present PresentPixmap() will not flip at the proper target_msc for a non-zero target_msc if VRR mode is active with this patch. They'd often flip one frame too early. However, this limitation should not matter much in VRR mode, as scheduling based on vblank counts is pretty futile/unusable under variable refresh duration anyway, so no real extra harm is done.

2018-11-28drm/amdgpu: Set FreeSync state using drm VRR propertiesNicholas Kazlauskas1-7/+0
Support for AMDGPU specific FreeSync properties and ioctls are dropped from amdgpu_dm in favor of supporting drm variable refresh rate properties. The notify_freesync and set_freesync_property functions are dropped from amdgpu_display_funcs. The drm vrr_capable property is now attached to any DP/HDMI connector. Its value is updated accordingly to the connector's FreeSync capabiltiy. The freesync_enable logic and ioctl control has has been dropped in favor of utilizing the vrr_enabled on the drm CRTC. This allows for more fine grained atomic control over which CRTCs should support variable refresh rate. To handle state changes for vrr_enabled it was easiest to drop the forced modeset on freesync_enabled change. This patch now performs the required stream updates when planes are flipped. This is done for a few reasons: (1) VRR stream updates can be done in the fast update path (2) amdgpu_dm_atomic_check would need to be hacked apart to check desired variable refresh state and capability before the CRTC disable pass. (3) Performing VRR stream updates on-flip is needed for enabling BTR support. VRR packets and timing adjustments are now tracked and compared to previous values sent to the hardware.

2018-11-26drm/amd: Add abm level drm propertyDavid Francis1-0/+2
Adaptive Backlight Management (ABM) is a feature that reduces backlight level to save power, while increasing pixel contrast and pixel luminance to maintain readability and image quality. ABM will adjust in response to the pixel luminance of the displayed content. ABM is made available as a drm property on eDP monitors called "abm level", which ranges from 0 to 4. When this property is set to 0, ABM is off. Levels 1 to 4 represent different ranges of backlight reduction. At higher levels both the backlight reduction and pixel adjustment will be greater. ABM requires DMCU firmware, which is currently available for Raven ASICs only. If the feature does not work, please ensure your firmware is up to date. v2: Fix commit message, only attach property if DMCU loaded v3: Store ABM level in crtc state to accommodate dc v4: Fix ABM saving on dpms cycle Signed-off-by: David Francis <David.Francis@amd.com> Reviewed-by: Harry Wentland <harry.wentland@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2018-11-19drm/amdgpu: Add amdgpu "max bpc" connector property (v2)Nicholas Kazlauskas1-0/+2
[Why] Many panels support more than 8bpc but some modes are unavailable while running at greater than 8bpc due to DP/HDMI bandwidth constraints. Support for more than 8bpc was added recently in the driver but it defaults to the maximum supported bpc - locking out these modes. This should be a user configurable option such that the user can select what bpc configuration they would like. [How] This patch introduces the "max bpc" amdgpu driver specific connector property so the user can limit the maximum bpc. It ranges from 8 to 16. This doesn't directly set the preferred bpc for the panel since it follows Intel's existing driver conventions. This proprety should be removed once common drm support for max bpc lands. v2: rebase on upstream (Alex) Signed-off-by: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> Acked-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Harry Wentland <harry.wentland@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2017-05-10drm/vblank: drop the mode argument from drm_calc_vbltimestamp_from_scanoutposDaniel Vetter1-0/+3
If we restrict this helper to only kms drivers (which is the case) we can look up the correct mode easily ourselves. But it's a bit tricky: - All legacy drivers look at crtc->hwmode. But that is updated already at the beginning of the modeset helper, which means when we disable a pipe. Hence the final timestamps might be a bit off. But since this is an existing bug I'm not going to change it, but just try to be bug-for-bug compatible with the current code. This only applies to radeon&amdgpu. - i915 tries to get it perfect by updating crtc->hwmode when the pipe is off (i.e. vblank->enabled = false). - All other atomic drivers look at crtc->state->adjusted_mode. Those that look at state->requested_mode simply don't adjust their mode, so it's the same. That has two problems: Accessing crtc->state from interrupt handling code is unsafe, and it's updated before we shut down the pipe. For nonblocking modesets it's even worse. For atomic drivers try to implement what i915 does. To do that we add a new hwmode field to the vblank structure, and update it from drm_calc_timestamping_constants(). For atomic drivers that's called from the right spot by the helper library already, so all fine. But for safety let's enforce that. For legacy driver this function is only called at the end (oh the fun), which is broken, so again let's not bother and just stay bug-for-bug compatible. The benefit is that we can use drm_calc_vbltimestamp_from_scanoutpos directly to implement ->get_vblank_timestamp in every driver, deleting a lot of code. v2: Completely new approach, trying to mimick the i915 solution. v3: Fixup kerneldoc. v4: Drop the WARN_ON to check that the vblank is off, atomic helpers currently unconditionally call this. Recomputing the same stuff should be harmless. v5: Fix typos and move misplaced hunks to the right patches (Neil). v6: Undo hunk movement (kbuild).

2017-05-01Revert "drm/amdgpu: Refactor flip into prepare submit and submit. (v3)"Michel Dänzer1-15/+0
This reverts commit cb341a319f7e66f879d69af929c3dadfc1a8f31e. The purpose of the refactor was for amdgpu_crtc_prepare/submit_flip to be used by the DC code, but that's no longer the case.

Make pflip atomic friendly. Split the fuinction into whatever can fail part and the actual flip submit part. Call the pre-submit function before atomic states are swapped so in case of error we can fail the IOCTL. v2: Update due to target_vblank code change. Fix identetation.

2016-12-18drm: Don't include <drm/drm_encoder.h> in <drm/drm_crtc.h>Laurent Pinchart1-0/+1
<drm/drm_crtc.h> used to define most of the in-kernel KMS API. It has now been split into separate files for each object type, but still includes most other KMS headers to avoid breaking driver compilation. As a step towards fixing that problem, remove the inclusion of <drm/drm_encoder.h> from <drm/drm_crtc.h> and include it instead where appropriate. Also remove the forward declarations of the drm_encoder and drm_encoder_helper_funcs structures from <drm/drm_crtc.h> as they're not needed in the header. <drm/drm_encoder.h> now has to include <drm/drm_mode.h> and contain a forward declaration of struct drm_encoder in order to allow including it as the first header in a compilation unit.
