When paging queue is enabled, it use the second page of doorbell. The AMDGPU_DOORBELL64_MAX_ASSIGNMENT definition assumes all the kernel doorbells are in the first page. So with paging queue enabled, the total kernel doorbell range should be original num_doorbell plus one page (0x400 in dword), not *2.

[Why] With scaling, underscan and abm changes we can end up calling commit_planes_to_stream in commit_tail. This call uses dm_state->context which can be NULL if the commit was a fast update. [How] Use dc_state instead since that can't be NULL unless the system ran out of memory.

For XGMI hive case do reset in steps where each step iterates over all devs in hive. This especially important for asic reset since all PSP FW in hive must come up within a limited time (around 1 sec) to properply negotiate the link. Do this by refactoring amdgpu_device_gpu_recover and amdgpu_device_reset into pre_asic_reset, asic_reset and post_asic_reset functions where is part is exectued for all the GPUs in the hive before going to the next step. v2: Update names for amdgpu_device_lock/unlock functions. v3: Introduce per hive locking to avoid multiple resets for GPUs in same hive. v4: Remove delayed_workqueue()/ttm_bo_unlock_delayed_workqueue() - they are copy & pasted over from radeon and on amdgpu there isn't any reason for that any more.

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.

When variable refresh rate is active the hardware counter can return a position >= vtotal. This results in a vpos being returned from amdgpu_display_get_crtc_scanoutpos that's a positive value. The positive value indicates to the caller that the display is currently in scanout when the display is actually still in vblank. This is because the vfront porch duration is unknown with variable refresh active and will end when either a page flip occurs or the timeout specified by the driver/display is reached. The behavior of the amdgpu_display_get_crtc_scanoutpos remains the same when the position is below vtotal. When the position is above vtotal the function will return a value that is effectively -vbl_end, the size of the vback porch. The only caller affected by this change is the DRM helper for calculating vblank timestamps. This change corrects behavior for calculating the page flip timestamp from being the previous timestamp to the calculation to the next timestamp when position >= vtotal.

This patch introduces the 'vrr_enabled' CRTC property to allow dynamic control over variable refresh rate support for a CRTC. This property should be treated like a content hint to the driver - if the hardware or driver is not capable of driving variable refresh timings then this is not considered an error. Capability for variable refresh rate support should be determined by querying the vrr_capable drm connector property. It is worth noting that while the property is intended for atomic use it isn't filtered from legacy userspace queries. This allows for Xorg userspace drivers to implement support.

Modern display hardware is capable of supporting variable refresh rates. This patch introduces the "vrr_capable" property on the connector to allow userspace to query support for variable refresh rates. Atomic drivers should attach this property to connectors that are capable of driving variable refresh rates using drm_connector_attach_vrr_capable_property(). The value should be updated based on driver and hardware capability by using drm_connector_set_vrr_capable_property().

[Why] Two non-blocking commits in succession can result in a sequence where the same dc->current_state is queried for both commits. 1. 1st commit -> check -> commit -> swaps atomic state -> queues work 2. 2nd commit -> check -> commit -> swaps atomic state -> queues work 3. 1st commit work finishes The issue with this sequence is that the same dc->current_state is read in both atomic checks. If the first commit modifies streams or planes those will be missing from the dc->current_state for the second atomic check. This result in many stream and plane errors in atomic commit tail. [How] The driver still needs to track old to new state to determine if the commit in its current implementation. Updating the dc_state in atomic tail is wrong since the dc_state swap should be happening as part of drm_atomic_helper_swap_state *before* the worker queue kicks its work off. The simplest replacement for the subclassing (which doesn't properly manage the old to new atomic state swap) is to use the drm private object helpers. While some of the dc_state members could be merged into dm_crtc_state or dm_plane_state and copied over that way it is easier for now to just treat the whole dc_state structure as a single private object. This allows amdgpu_dm to drop the dc->current_state copy from within atomic check. It's replaced by a copy from the current atomic state which is propagated correctly for the sequence described above. Since access to the dm_state private object is now locked this should also fix issues that could arise if submitting non-blocking commits from different threads.

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>

DMCU IRAM must be loaded by the driver before DMCU can function. Move the IRAM code out of the shadows and into a new file modules/power/power_helpers.c The IRAM table contains the backlight curve and ABM parameters Add this new file to the Makefiles Call dmcu_load_iram in late init of DM Move struct dmcu_version from dc.h to dmcu.h to allow dmcu to be included on its own 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>

We observe black lines (underflow) on display when playing a 4K video with UVD. On Disabling Low memory P state this issue is not seen. In this patch ,disabling low memory P state only when video size >= 4k. Multiple runs of power measurement shows no impact Signed-off-by: suresh guttula <suresh.guttula@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
