At one point, the GPU command verifier and user-space handle manager couldn't properly protect GPU clients from accessing each other's data. Instead there was an elaborate mechanism to make sure only the active master's primary clients could render. The other clients were either put to sleep or even killed (if the master had exited). VRAM was evicted on master switch. With the advent of render-node functionality, we relaxed the VRAM eviction, but the other mechanisms stayed in place. Now that the GPU command verifier and ttm object manager properly isolates primary clients from different master realms we can remove the master switch related code and drop those legacy features.

As the code is currently written, if read_smc_arg were ever NULL, arg would fail to be initialized but the code would continue executing as normal because the return value would just be zero. There are a few different possible solutions to resolve this class of warnings which have appeared in these drivers before: 1. Assume the function pointer will never be NULL and eliminate the wrapper macros. 2. Have the wrapper macros initialize arg when the function pointer is NULL. 3. Have the wrapper macros return an error code instead of 0 when the function pointer is NULL so that the callsites can properly bail out before arg can be used. 4. Initialize arg at the top of its function. Number four is the path of least resistance right now as every other change will be driver wide so do that here. I only make the comment now as food for thought.

[Why] Underflow can occur in the case where we change buffer pitch, DCC state, rotation or mirroring for a plane while also performing an immediate flip. It can also generate a p-state warning stack trace on DCN1 which is typically observed during the cursor handler pipe locking because of how frequent cursor updates can occur. [How] Store the update type on each CRTC - every plane will have access to the CRTC state if it's flipping. If the update type is not UPDATE_TYPE_FAST then the immediate flip should be disallowed. No changes to the target vblank sequencing need to be done, we just need to ensure that the surface registers do a double buffered update. Signed-off-by:

[Why] Pitch, DCC, rotation and mirroring can result in updates that are not UPDATE_TYPE_FAST but UPDATE_TYPE_MED instead. DC needs dc_plane_info and dc_plane_size to make this determination and we aren't currently passing this into DC during atomic check. Underflow (visible or non-visible) can occur if we don't validate this correctly. This also will generally trigger p-state warnings, typically via the cursor handler when locking. [How] Get the framebuffer tiling flags and generate the required structures for DC in dm_determine_update_type_for_commit. Signed-off-by:
