*	gallium/u_transfer_helper: Add support for separate Z24/S8 as well.	Kenneth Graunke	2018-10-14	1	-5/+6
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	u_transfer_helper already had code to handle treating packed Z32_S8 as separate Z32_FLOAT and S8_UINT resources, since some drivers can't handle that interleaved format natively. Other hardware needs depth and stencil as separate resources for all formats. For example, V3D3 needs this for 24-bit depth as well. This patch adds a new flag to lower all depth/stencils formats, and implements support for Z24_UNORM_S8_UINT. (S8_UINT_Z24_UNORM is left as an exercise to the reader, preferably someone who has access to a machine that uses that format.) Reviewed-by: Eric Anholt <[email protected]>
*	gallium/util: add u_transfer_helper	Rob Clark	2017-12-15	1	-0/+135
	Add a new helper that drivers can use to emulate various things that need special handling in particular in transfer_map: 1) z32_s8x24.. gl/gallium treats this as a single buffer with depth and stencil interleaved but hardware frequently treats this as separate z32 and s8 buffers. Special pack/unpack handling is needed in transfer_map/unmap to pack/unpack the exposed buffer 2) fake RGTC.. GPUs designed with GLES in mind, but which can other- wise do GL3, if native RGTC is not supported it can be emulated by converting to uncompressed internally, but needs pack/unpack in transfer_map/unmap 3) MSAA resolves in the transfer_map() case v2: add MSAA resolve based on Eric's "gallium: Add helpers for MSAA resolves in pipe_transfer_map()/unmap()." patch; avoid wrapping pipe_resource, to make it possible for drivers to use both this and threaded_context.
