This causes unnecessary delay when enabling the link and produces a warning affecting multiple IGT tests. [How] Don't wait for the symclk to be on here because firmware already does. Don't wait for reset if we know the symclk isn't on. Split the reset into a helper function that checks the bit and decides whether or not a delay is sufficient.

This is likely due to insufficient DCC meta data buffered immediately after the mclk switch. [How] Add workaround to increase phantom pipe vactive height by meta_row_height number of lines, thus increasing the amount of meta data buffered immediately after mclk switch finishes.

The additional macro needed were added to dwb ip specific header file (dcnxx_dwb.h) instead of soc resource file (dcnxx_resource.c). Due to this pattern, BASE macro had to be redefined in dcnxx_dwb.h, which in turn needed us to undefine them in the resource file. [How] Add a separate macro for DWB access to the resource files that need it instead of defining them in DWB ip header file. This will enable us to reuse the BASE macro defined in the resource file.

In this case, it seems to have come back to bite us because as a result of simply returning false from compute_mst_dsc_configs_for_state(), amdgpu had no way of telling when a deadlock happened from these helpers.

Basically, it appears that we've been grabbing the entirely wrong mutex in the MST DSC computation code for amdgpu! While we've been grabbing: amdgpu_dm_connector->mst_mgr That's zero-initialized memory, because the only connectors we'll ever actually be doing DSC computations for are MST ports. Which have mst_mgr zero-initialized, and instead have the correct topology mgr pointer located at: amdgpu_dm_connector->mst_port->mgr; I'm a bit impressed that until now, this code has managed not to crash anyone's systems! It does seem to cause a warning in LOCKDEP though: [ 66.637670] DEBUG_LOCKS_WARN_ON(lock->magic != lock) This was causing the problems that appeared to have been introduced by: commit 4d07b0bc4034 ("drm/display/dp_mst: Move all payload info into the atomic state") This wasn't actually where they came from though. Presumably, before the only thing we were doing with the topology mgr pointer was attempting to grab mst_mgr->lock. Since the above commit however, we grab much more information from mst_mgr including the atomic MST state and respective modesetting locks. This patch also implies that up until now, it's quite likely we could be susceptible to race conditions when going through the MST topology state for DSC computations since we technically will not have grabbed any lock when going through it. So, let's fix this by adjusting all the respective code paths to look at the right pointer and skip things that aren't actual MST connectors from a topology.
