[Why & How] Due to some code flow constraints, we need to defer dc_lock needed works from dc_link_handle_hpd_rx_irq(). Thus, do following changes: * Change allow_hpd_rx_irq() from static to public * Change handle_automated_test() from static to public * Extract link lost handling flow out from dc_link_handle_hpd_rx_irq() and put those into a new function dc_link_dp_handle_link_loss() * Add one option parameter to decide whether defer works within dc_link_handle_hpd_rx_irq() Acked-by:

[why] According to DP specs dfp cap ext validation is only for branch device withou 128b/132b channel coding support and downstream of the branch device doesn't have compression. Therefore we are adding conditions to only do dfp cap extension validation for branch devcie supporting 8b/10b channel coding only and it has no DSC passthrough capability. Acked-by:

[why] Before get dsc bw range is used to compute DSC bw range based on the given fixed bpp min/max input. The new change will merge any specs, signal, timing specific bpp range decision into this function. So the function needs to make a decision with all aspects considered. Acked-by:

On some GPUs the PCIe atomic requirement for KFD depends on the MEC firmware version. Add a firmware version check for this. The minimum firmware version that works without atomics can be updated in the device_info structure for each GPU type. Move PCIe atomic detection from kgd2kfd_probe into kgd2kfd_device_init because the MEC firmware is not loaded yet at the probe stage. Signed-off-by:

Add manual sclk/vddc setting supoort via pp_od_clk_voltage sysfs to maintain consistency with other asics. As cyan skillfish doesn't support DPM, there is only a single frequency and voltage to adjust. v2: maintain consistency and add command guide. v3: adjust user settings storage and coding style. Command guide: echo vc point sclk vddc > pp_od_clk_voltage "vc" - sclk voltage curve "point" - must be 0 "sclk" - target value of sclk(MHz), should be in safe range "vddc" - target value of vddc(mV), a 6.25(mV) stepping is recommended and should be in safe range (the real vddc is an approximation of target value) echo c > pp_od_clk_voltage "c" - commit the changes of sclk and vddc, only after the commit command, the target values set by "vc" command will take effect echo r > pp_od_clk_voltage "r" - reset sclk and vddc to default value, a subsequent commit command is needed to take effect Example: 1) Check default sclk and vddc $ cat pp_od_clk_voltage OD_SCLK: 0: 1800Mhz * OD_VDDC: 0: 862mV * OD_RANGE: SCLK: 1000Mhz 2000Mhz VDDC: 700mV 1129mV 2) Set sclk to 1500MHz and vddc to 700mV $ echo vc 0 1500 700 > pp_od_clk_voltage $ echo c > pp_od_clk_voltage $ cat pp_od_clk_voltage OD_SCLK: 0: 1500Mhz * OD_VDDC: 0: 693mV * OD_RANGE: SCLK: 1000Mhz 2000Mhz VDDC: 700mV 1129mV 3) Reset sclk and vddc to default $ echo r > pp_od_clk_voltage $ echo c > pp_od_clk_voltage $ cat pp_od_clk_voltage OD_SCLK: 0: 1800Mhz * OD_VDDC: 0: 874mV * OD_RANGE: SCLK: 1000Mhz 2000Mhz VDDC: 700mV 1129mV NOTE: We don't specify an explicit safe range, you can set any values between min and max at your own risk.

In amdgpu_dm_atomic_check, dc_validate_global_state is called. On failure this logs a warning to the kernel journal. However warnings shouldn't be used for atomic test-only commit failures: user-space might be perfoming a lot of atomic test-only commits to find the best hardware configuration. Downgrade the log to a regular DRM atomic message. While at it, use the new device-aware logging infrastructure. This fixes error messages in the kernel when running gamescope [1].

As noted in the "Deprecated Interfaces, Language Features, Attributes, and Conventions" documentation [1], size calculations (especially multiplication) should not be performed in memory allocator (or similar) function arguments due to the risk of them overflowing. This could lead to values wrapping around and a smaller allocation being made than the caller was expecting. Using those allocations could lead to linear overflows of heap memory and other misbehaviors. So, refactor the code a bit to use the purpose specific kcalloc() function instead of the calculated size argument in the kzalloc() function.
