[Why] Specifically to one panel, TCON is able to accept active video signal quickly, but the Source Driver requires 2-3 frames of extra time. It is a Panel issue since TCON needs to take care of all Sink requirements including Source Driver. But in this case it does not. Customer is asking to add fixed T7 delay as panel workaround.

[Why] -Pass and use pixel clock in 100 Hz to Audio for HDMI audio DTO for Audio wall clock programming so audio DTO gets increased precision for timings with /1001 factor. -For HDMI TMDS for N and CTS ACR tables are based on 10 KHz units, these does not need to be modified as N and CTS values are still valid using current tables.

[Why] For DCE110, DCE112 and DCE120 the max_clks_by_state for the clk_mgr are copied from their respective table before the call to dce_clk_mgr_construct, but then dce_clk_mgr_construct overwrites these with the dce80_max_clks_by_state.

[Why] Fixes issue when we have a display connected using a passive dongle and then emulate over it using a DP connection at 1 x 1.62 Ghz. System hangs because register bus returns back 0xFFFFFFFF for all register reads after setting register DIG_BE_CNTL in dcn10_link_encoder_connect_dig_be_to_fe(). Hang occurs later when trying to do a register read. [How] At the start of the emulation, dc_link_set_preferred_link_settings() and dp_retrain_link_dp_test() is called, even though it is connected using a passive dongle. Add an extra condition in dp_retrain_link_dp_test() to check for link->dongle_max_pix_clk > 0. This is the only way we know if the connection is using passive dongle so we don't retrain DP.

[Why] There are certain MST displays (i.e. Dell P2715Q) that although have the MST feature set to off may still report it is a branch device and a non-zero value for downstream port present.

The GDS and GWS blocks default to allowing all VMIDs to access all entries. Graphics VMIDs can handle setting these limits when the driver launches work. However, compute workloads under HWS control don't go through the kernel driver. Instead, HWS firmware should set these limits when a process is put into a VMID slot. Disable access to these devices by default by turning off all mask bits (for OA) and setting BASE=SIZE=0 (for GDS and GWS) for all compute VMIDs. If a process wants to use these resources, they can request this from the HWS firmware (when such capabilities are enabled). HWS will then handle setting the base and limit for the process when it is assigned to a VMID. This will also prevent user kernels from getting 'stuck' in GWS by accident if they write GWS-using code but HWS firmware is not set up to handle GWS reset. Until HWS is enabled to handle GWS properly, all GWS accesses will MEM_VIOL fault the kernel. v2: Move initialization outside of SRBM mutex Signed-off-by:
