anv: Use a separate pool for binding tables when soft pinning
Soft pinning lets us satisfy the binding table address requirements without using both sides of a growing state_pool. If you do use both sides of a state pool, then you need to read the state pool's center_bo_offset (with the device mutex held) to know the final offset of relocations that target the state pool bo. By having a separate pool for binding tables that only grows in the forward direction, the center_bo_offset is always 0 and relocations don't need an update pass to adjust relocations with the mutex held. v2: - don't introduce a separate state flag for separate binding tables (Jason) - replace bo and map accessors with a single binding_table_pool accessor (Jason) v3: - assert bt_block->offset >= 0 for the separate binding table (Jason) Reviewed-by: Jason Ekstrand <[email protected]> Reviewed-by: Jordan Justen <[email protected]>
