[WHY] While Link Training is being performed, and the LTTPRs are in Non-LTTPR or LTTPR Transparent mode, any DPCD registers besides those used for Link Training are not to be accessed. The spec defines the link training registers as DP_TRAINING_PATTERN_SET (102h) to DP_TRAINING_LANE3_SET (106h), and DP_LANE0_1_STATUS (202h) to DP_ADJUST_REQUEST_LANE2_3 (207h). [HOW] Move the current write to DPCD Address DP_LINK_TRAINING_PATTERN_SET out of its conditional block. Signed-off-by:

Previous change had been reverted since it caused hang. Remake change to avoid defect. [Why] 1. Driver use umachannelnumber to calculate watermarks for stutter. In asymmetric memory config, the actual bandwidth is less than dual-channel. The bandwidth should be the same as single-channel. 2. We found single rank dimm need additional delay time for stutter. [How] Get information from each DIMM. Treat memory config as a single-channel for asymmetric memory in bandwidth calculating. Add additional delay time for single rank dimm.

This patch is to remove the "set" function of pp_dpm_mclk for vangogh. For vangogh, mclk bonds with fclk, they will lock each other on the same perfomance level. But according to the smu message from pmfw, only fclk is allowed to set value manually, so remove the unnecessary code of "set" function for mclk. Signed-off-by:

If we skipped loading MEC2 firmware separately from MEC, then MEC2 will be running the same firmware image. Copy the MEC version and feature numbers into MEC2 version and feature numbers. This is needed for things like GWS support, where we rely on knowing what version of firmware is running on MEC2. Leaving these MEC2 entries blank breaks our ability to version-check enables and workarounds. Signed-off-by:

Add bad_page_cnt_threshold to debugfs, an optional file system used for debugging, for reporting purposes only--it usually matches the size of EEPROM but may be different depending on the "bad_page_threshold" kernel module option. The "bad_page_cnt_threshold" is a dynamically computed value. It depends on three things: the VRAM size; the size of the EEPROM (or the size allocated to the RAS table therein); and the "bad_page_threshold" module parameter. It is a dynamically computed value, when the amdgpu module is run, on which further parameters and logic depend, and as such it is helpful to see the dynamically computed value in debugfs.
