If some pages fail to migrate to system memory, don't update prange->actual_loc = 0. This prevents endless CPU page faults after partial migration failures due to contested page locks. Migration to RAM must be complete during migrations from VRAM to VRAM and during evictions. Implement retry and fail if the migration to RAM fails. Signed-off-by:

Stack and heap pages tend to be shared by many small allocations. Concurrent access by CPU and GPU is therefore likely, which can lead to thrashing. Avoid this by setting the preferred location to system memory. Signed-off-by:

The preferred location should be used as the migration destination whenever it is accessible by the faulting GPU. System memory is always accessible. Peer memory is accessible if it's in the same XGMI hive. Signed-off-by:

[Why] - DPIA MST slot registers are not programmed during payload allocation and hence MST does not work with DPIA. - HPD RX interrupts are not handled for DPIA.

[WHY] On certain configs, SMU clock table voltages don't match which cause parser to behave incorrectly by leaving dcfclk and socclk table entries unpopulated. [HOW] Currently the function that finds the corresponding clock for a given voltage only checks for exact voltage level matches. In the case that no match gets found, parser now falls back to searching for the max clock which meets the requested voltage (i.e. its corresponding voltage is below requested). Signed-off-by:

Why: For audio packet type 0x02, there are 2 Layouts: Layout = 0 for 2 channels and Layout = 1 for > 2 channels. Layout will affect bandwidth check. Currently, for HDMI FRL, Layout field isn't set and has a default value of 0, so theoretically only 2-channel audio for audio packet type 0x02 is supported now. How: 1. Set Layout properly according to maximum audio channel numbers for audios with audio packet type 0x02. 2. 8ch LPCM audio is not supported for timing modes with v_active <= 576. Reviewed-by:
