[Why] For panels with pixel clock > 1200MHz that require ODM in pre-OS, when driver is disabled in OS, odm is enabled. Upon driver enablement, corruption is seen if odm was originally enabled. DP_PIXEL_COMBINE and pixelclk must be programmed prior to programming the optc-odm registers. However, eDP displays aren't blanked prior to initializing odm in this case. [How] Upon driver enablement, check whether odm is enabled, if so, blank eDP prior to programming optc-odm registers. Reviewed-by:

[Why] LTTPR capable devices on the DisplayPort path may assume that extended LTTPR AUX timeouts will be used after LTTPR capabilities are read. When DPTX operates in non-LTTPR mode, AUX timeouts are not extended and this can result in AUX transactions timing out. [How] Use shared helper function to determine LTTPR mode and do not read LTTPR capabilities in non-LTTPR mode. Reviewed-by:

The last case label can write two buffers 'mc_reg_address[j]' and 'mc_data[j]' with 'j' offset equal to SMC_NISLANDS_MC_REGISTER_ARRAY_SIZE since there are no checks for this value in both case labels after the last 'j++'. Instead of changing '>' to '>=' there, add the bounds check at the start of the second 'case' (the first one already has it). Also, remove redundant last checks for 'j' index bigger than array size. The expression is always false. Moreover, before or after the patch 'table->last' can be equal to SMC_NISLANDS_MC_REGISTER_ARRAY_SIZE and it seems it can be a valid value.

[Why] Once mst topology is constructed, later on new connected monitors are reported to source by CSN message. Within CSN, there is no carried info of DPCD_REV comparing to LINK_ADDRESS reply. As the result, we might leave some ports connected to DP but without DPCD revision number which will affect us determining the capability of the DP Rx. [How] Send out remote DPCD read when the port's dpcd_rev is 0x0 in detect_ctx(). Firstly, read out the value from DPCD 0x2200. If the return value is 0x0, it's likely the DP1.2 DP Rx then we reques revision from DPCD 0x0 again. Reviewed-by:

[Why] The existing calculations in DCN3.1 were placeholder and need to be replaced with HW team approved calculations. [How] The new calculations add new parameters to the bounding box and pipe params - VblankNom and the bounding box default. The placeholder calculations are dropped from DCN3.1 in the meantime while we work out hardware approved replacements. Also fix a bug where we wipe out other register contents with a REG_SET instead of a REG_UPDATE for the register we were programming the min_dst_y_next_start_optimized. Reviewed-by:

[WHY] For additional power savings, PSR SU (also referred to as PSR2) can be enabled on eDP panels with PSR SU support. PSR2 saves more power compared to PSR1 by allowing more opportunities for the display hardware to be shut down. In comparison to PSR1, Shut down can now occur in-between frames, as well as in display regions where there is no visible update. In otherwords, it allows for some display hw components to be enabled only for a **selectively updated** region of the visible display. Hence PSR SU. [HOW] To define the SU region, support from the OS is required. OS needs to inform driver of damaged regions that need to be flushed to the eDP panel. Today, such support is lacking in most compositors. Therefore, an in-between solution is to implement PSR SU for MPO and cursor scenarios. The plane bounds can be used to define the damaged region to be flushed to panel. This is achieved by: * Leveraging dm_crtc_state->mpo_requested flag to identify when MPO is enabled. * If MPO is enabled, only add updated plane bounds to dirty region. Determine plane update by either: * Existence of drm damaged clips attached to the plane (added by a damage-aware compositor) * Change in fb id (flip) * Change in plane bounds (position and dimensions) * If cursor is enabled, the old_pos and new_pos of cursor plus cursor size is used as damaged regions(*). (*) Cursor updates follow a different code path through DC. PSR SU for cursor is already implemented in DC, and the only thing required to enable is to set DC_PSR_VERSION_SU_1 on the eDP link.

[why] To involve the cursor position into dirty rectangle calculation.

[why] Currently the psr configuration parameters are hardcoded before feeding into the DC helper before passing to DMUB FW. We'd rework to call a shared helper to calculate/update generic psr config fields which are relying on the stream timing and eDP sink PSR caps to avoid hard-coding. [how] - drop part of hard-coded psr config fields by replacing w/ the call of helper from DM before feeding into DC link setup psr helper - For those DM specific psr config fields, e.g. allow smu opt, is not to be set/updated from the shared helper but to rely on the DC feature mask - for the psr version field in psr_config structure, since only the field psr_version of DC link psr_settings matters for that fed to DMUB FW, thus no need to set/update the psr_version field of psr_config structure.

[why] When DC driver send PSR exit dmub command to DMUB FW, it might not wait until PSR exit. Then it may hit the following deadlock situation. 1. DC driver send HW LOCK command to DMUB FW due to frame update 2. DMUB FW Set the HW lock 3. DMUB execute PSR exit sequence and stuck at polling DPG Pending register due to the HW Lock is set 4. DC driver ask DMUB FW to unlock HW lock, but DMUB FW is polling DPG pending register [how] The reason why DC driver doesn't wait until PSR exit is because some of the PSR state machine state is not update the dc driver. So when DC driver read back the PSR state, it take the state for PSR inactive. Signed-off-by:

[why] The current PSR SU programming margin is fixed base on FHD 60HZ panel. If the resolution and refresh rate become higher, the time of current margin might not cover the programming SU time. [how] Notice that the programming SU time is the same among different panels. Instead of fixing the margin with target line number, change the margin unit to micro second which indicate the time needed for programming SU. Then FW set the margin line number base on the line time and margin time. Signed-off-by:

Starting from SIENNA CICHLID asic supports two gfx pipes, enabling two graphics queues, 1 on each pipe, pipe0 queue0 would be the normal piority queue and pipe1 queue0 would be the high priority queue Only one queue per pipe is visble to SPI, SPI looks at the priority value assigned to CP_GFX_HQD_QUEUE_PRIORITY from each of the queue's HQD/MQD. Create contexts applying AMDGPU_CTX_PRIORITY_HIGH which submits job to the high priority queue on GFX pipe1. There would be starvation of LP workload if HP workload is always available. v2: - remove unnecessary check(Nirmoy) - make pipe1 hardware support a separate patch(Nirmoy) - remove duplicate code(Shashank) - add CSA support for second gfx pipe(Alex) v3(Christian): - fix incorrect indentation - merge COMPUTE and GFX switch cases as both calls the same function. v4: - rebase w/ latest code base Signed-off-by:
