if (!(tmp & flag)) condition will always evaluate to true when the flag is 0x0 (AMDGPU_RLCG_GC_WRITE). Instead check that address bits are cleared to determine whether the command is complete.

drm/amdgpu: Separate vf2pf work item init from virt data exchange

2021-12-16T19:08:20Z

We want to be able to call virt data exchange conditionally after gmc sw init to reserve bad pages as early as possible. Since this is a conditional call, we will need to call it again unconditionally later in the init sequence. Refactor the data exchange function so it can be called multiple times without re-initializing the work item. v2: Cleaned up the code. Kept the original call to init_exchange_data() inside early init to initialize the work item, afterwards call exchange_data() when needed.
