Expose sclk (gfx clock) and mclk (memory clock) via hwmon compatible interface. hwmon does not actually formally specify a frequency type attribute, but these are compatible with the format of the other attributes exposed via hwmon. Units are hertz. freq1_input - GPU gfx/compute clock in hertz freq2_input - GPU memory clock in hertz (dGPU only) Reviewed-by:

[Why] Hardware support for Delta Color Compression (DCC) decompression is available in DC for GFX9 but there's no way for userspace to enable the feature. Enabling the feature can provide improved GFX performance and power savings in many situations. [How] The GFX9 DCC parameters are passed to amdgpu_dm from AMDGPU via the amdgpu_bo tiling_flags. The plane capability is queried and the parameters are set accordingly. The DCC address is given via a 256 byte aligned offset on the framebuffer address. The DCC address is updated whenever the buffer address changes. Signed-off-by:

Christian König authored
When an ring buffer overflow happens the appropriate bit is set in the WPTR register which is also written back to memory. But clearing the bit in the WPTR doesn't trigger another memory writeback. So what can happen is that we end up processing the buffer overflow over and over again because the bit is never cleared. Resulting in a random system lockup because of an infinite loop in an interrupt handler. This is 100% reproducible on Vega10, but it's most likely an issue we have in the driver over all generations all the way back to radeon. v2: rebase Signed-off-by:

[Why] When XGMI is enabled, we need to adjust the dprefclk according to the WAFL link's spread spectrum info. This is for VG20 (DCE121) only. [How] dce_clk_mgr already stores SS info, currently being used by audio clock. Therefore, patch the clk_mgr's SS info with the xGMI SS info, if xGMI is enabled. For display clock, adjust it during dce12_update_clocks() before calling set_clock(). Since we rely on a mmhub register to reliably determine if xGMI is enabled, the patching step needs to happen after resource_construct() has initialized the hardware sequencer. Signed-off-by:

[Why] This fixes an regression introduced by: drm/amd/display: add stream ID and otg instance in dc_stream_state During driver initialization, a null pointer deref is raised. This is caused by searching for a stream status in the dc->current_state before the dc_state swap happens at the end of dc_commit_state_no_check(). Since the swap has not happened, the dc_state to be swapped in should be searched, and not dc->current_state. [How] Add a function that searches for the stream status within the given dc_state, instead of dc->current_state. Use that before the state swap happens in dc_commit_state_no_check(). Also remove duplicate occurrences of this function in amdgpu_dm.c. Signed-off-by: -
