This fix the deadlock with the BO reservations during SVM_BO evictions while allocations in VRAM are concurrently performed. More specific, while the ttm waits for the fence to be signaled (ttm_bo_wait), it already has the BO reserved. In parallel, the restore worker might be running, prefetching memory to VRAM. This also requires to reserve the BO, but blocks the mmap semaphore first. The deadlock happens when the SVM_BO eviction worker kicks in and waits for the mmap semaphore held in restore worker. Preventing signal the fence back, causing the deadlock until the ttm times out. We don't need to hold the BO reservation anymore during validation and mapping. Now the physical addresses are taken from hmm_range_fault. We also take migrate_mutex to prevent range migration while validate_and_map update GPU page table. Signed-off-by:

[WHY] To enable dc links for USB4 DPIA ports and AUX command tunneling for YELLOW_CARP_B0. [HOW] 1) Created dc links for all USB4 DPIA ports in create_links(). dc_link_construct() implementation is split for legacy DDC and DPIAs. As usb4 has no ddc, ddc->ddc_pin will be set to NULL for its dc link and this parameter will be used to identify the dc links as DPIA. The dc link for DPIA is further to be enhanced with implementation for link encoder and link initialization. 2) usb4_dpia_count in struct resource_pool will be initialized to 4 in dcn31_resource_construct() if the DCN is YELLOW_CARP_B0. 3) Enabled DMUB AUX via outbox for YELLOW_CARP_B0.

[Why] Trying to enable multiple displays simultaneously exposed shortcomings with the algorithm for dynamic link encoder assignment. The main problems were: - Assuming stream order remained constant across states would sometimes lead to invalid DIG encoder assignment. - Incorrect logic for deciding whether or not a DIG could support a stream would also sometimes lead to invalid DIG encoder assignment. - Changes in encoder assignment were wholesale while updating of the pipe backend is incremental. This would lead to the hardware state not matching the software state even with valid encoder assignments. [How] The following changes fix the identified problems. - Use stream pointer rather than stream index to track streams across states. - Fix DIG compatibility check by examining the link signal type rather than the stream signal type. - Modify assignment algorithm to make incremental updates so software and hardware states remain coherent. Additionally: - Add assertions and an encoder assignment validation function link_enc_cfg_validate() to detect potential problems with encoder assignment closer to their root cause. - Reduce the frequency with which the assignment algorithm is executed. It should not be necessary for fast state validation. Reviewed-by:
