Add drm_dp_mst_dsc_aux_for_port. To enable DSC, the DSC_ENABLED register might have to be written on the leaf port's DPCD, its parent's DPCD, or the MST manager's DPCD. This function finds the correct aux for the job. As part of this, add drm_dp_mst_is_virtual_dpcd. Virtual DPCD is a DP feature new in DP v1.4, which exposes certain DPCD registers on virtual ports. v2: Remember to unlock mutex on all paths v3: Refactor to match coding style and increase brevity v4: - Check DSC capable MST sink connected directly to the device. - Check branch's port_parent to be set Cc: Lyude Paul <lyude@redhat.com> Reviewed-by:Wenjing Liu <Wenjing.Liu@amd.com> Signed-off-by:

This field on drm_dp_mst_branch was never filled It is initialized to zero when the port is kzallocced. When a port is added to the list, increment num_ports, and when a port is removed from the list, decrement num_ports. v2: remember to decrement on port removal v3: don't explicitly init to 0 v4: move decrement of num_ports to unlink_port function Reviewed-by:

Instead of having drm_dp_dpcd_read/write and drm_dp_mst_dpcd_read/write as entry points into the aux code, have drm_dp_dpcd_read/write handle both. This means that DRM drivers can make MST DPCD read/writes. v2: Fix spacing v3: Dump dpcd access on MST read/writes v4: Fix calling wrong function on DPCD write v5: delete deprecated include of drmP.h Reviewed-by:

As of DP1.4, ENUM_PATH_RESOURCES returns a bit indicating if FEC can be supported up to that point in the MST network. The bit is the first byte of the ENUM_PATH_RESOURCES ack reply, bottom-most bit (refer to section 2.11.9.4 of DP standard, v1.4) That value is needed for FEC and DSC support Store it on drm_dp_mst_port Reviewed-by:

With DSC, bpp can be fractional in multiples of 1/16. Change drm_dp_calc_pbn_mode to reflect this, adding a new parameter bool dsc. When this parameter is true, treat the bpp parameter as having units not of bits per pixel, but 1/16 of a bit per pixel v2: Don't add separate function for this v3: In the equation divide bpp by 16 as it is expected not to leave any remainder v4: Added DSC test parameters for selftest Reviewed-by:

Use filep->private_data to store a pointer to the kfd_process data structure. Take an extra reference for that, which gets released in the kfd_release callback. Check that the process calling kfd_ioctl is the same that opened the file descriptor. Return -EBADF if it's not, so that this error can be distinguished in user mode. Signed-off-by:

For high-res (8K) or HFR (4K120) displays, using uncompressed pixel formats like YCbCr444 would exceed the bandwidth of HDMI 2.0, so the "interesting" modes would be disabled, leaving only low-res or low framerate modes. This change lowers the pixel encoding to 4:2:2 or 4:2:0 if the max TMDS clock is exceeded. Verified that 8K30 and 4K120 are now available and working with a Samsung Q900R over an HDMI 2.0b link from a Radeon 5700. Reviewed-by:

[Why] Some combined docks will always trigger CP_IRQ but there's nothing the driver needs to take care of, but the CP_IRQ breaks the original hdcp state and triggers the driver to restart the authentication.

[WHY] Some monitors trigger HDCP2.x timeout after reinitializing (e.g. toggling HDR) by taking longer than expected to return h' (h prime) Previously the 200ms watchdog timer retry count would hit MAX_NUM_OF_ATTEMPTS (4), causing fallback to HDCP1.x [HOW] Adding a 1s delay after an h' watchdog timeout provides enough time for affected monitors to return h' in time without hitting MAX_NUM_OF_ATTEMPTS Signed-off-by:

Before, initialization of smu ip block would be skipped for sriov ASICs. But if there's only one VF being used, guest driver should be able to dump some HW info such as clks, temperature,etc. To solve this, now after onevf mode is enabled, host driver will notify guest. If it's onevf mode, guest will do smu hw_init and skip some steps in normal smu hw_init flow because host driver has already done it for smu. With this fix, guest app can talk with smu and dump hw information from smu. v2: refine the logic for pm_enabled.Skip hw_init by not changing pm_enabled. v3: refine is_support_sw_smu and fix some indentation issue.
