[Mesa-dev] [PATCH] gallium: unify transfer functions

[Marek Olšák]

Hi,

this is actually a very small cleanup that got unexpectedly big. I
really underestimated the size of gallium.

It's part of the plan discussed here:
http://www.mail-archive.com/mesa-dev@lists.freedesktop.org/msg17930.html

The idea is that get_transfer+transfer_map is folded into
transfer_map, and transfer_unmap+transfer_destroy is folded into
transfer_unmap. transfer_map must create and return the transfer
object and transfer_unmap must destroy it. transfer_map is successful
if the returned buffer pointer is not NULL. If transfer_map fails, the
pointer to the transfer object remains unchanged (i.e. doesn't have to
be NULL).

I couldn't send the patch to mesa-dev, because it's too big. It's here:

There are no piglit regressions on r600g, softpipe, and llvmpipe. I
haven't tested the other drivers nor have I tested the state trackers
not covered by piglit.

I get that I won't get a review of the whole patch, but at least an
ack would be appreciated. :)
