From: Thomas Hellstrom Date: Fri, 17 Apr 2009 09:47:30 +0000 (+0200) Subject: gallium: Create OGL state tracker wrappers for various CPU access operations. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e50dd26ca6d0eb0d0f97c2780020ea16e3d4a687;p=mesa.git gallium: Create OGL state tracker wrappers for various CPU access operations. There are two usage types of buffer CPU accesses: One where we try to use the buffer contents for multiple draw commands in a batch. (batch := sequence of commands that are flushed together), like incrementally adding bitmaps to a bitmap texture that is reallocated on flush. And one where we assume we can safely overwrite the old buffer contexts, like glTexSubImage. In this case we need to make sure all old drawing commands referencing the buffer are flushed before we map the buffer. This is easily forgotten. Add wrappers for the most common of these operations. The first type is prefixed with "st_no_flush" and the second type is prefixed with "st_cond_flush", where "cond" indicates that we attmpt to only flush if there is indeed unflushed draw commands referencing the buffer. Prefixed functions are screen::get_tex_transfer pipe_buffer_write pipe_buffer_read pipe_buffer_map Please use the wrappers whenever possible.
