[Mesa-dev] [PATCH 00/10] Rework of pb_cache_manager for removal of radeon_winsys_cs_handle

[Marek Olšák]

Hi,

This series addresses the weirdness in radeon drivers that every buffer has 2 handles:
- pb_buffer (== pb_cache_buffer)
- radeon_winsys_cs_handle (winsys-specific pb_buffer)

The inefficiency of converting pb_cache_buffer into the winsys-specific buffer made me introduce radeon_winsys_cs_handle a few years ago, which has been used for almost everything (map/unmap/command submission/etc.) and pb_buffer has only held the reference keeping the buffer alive.

Now it's time to do this right.

This series moves the pb_cache_manager logic into an independent module "pb_cache". Next, all dependencies on pb_manager are removed from both winsyses and the new module is used instead. The result is that pb_buffer is equal to radeon_winsys_cs_handle, and the latter can be removed.

Please review.

Marek
