commit 2e3714380027252ba17a11f23eae851d3f77ab02
Author: Eric Anholt <eric at anholt.net>

    intel: Add a little span cache to spead up readpixels by cutting syscalls.

commit d2d5abfaeb46fc7b4d4267a6c9e92420fc9b5334
Author: Eric Anholt <eric at anholt.net>
Date:   Tue Jul 22 15:20:07 2008 -0700

    intel-gem: Use pread/pwrite for span access.
    
    This will avoid clflushing entire buffers for small acesses, such as those
    commonly used by regression tests.

commit f0ca917924a749b1fa287cc9536607ace03c2f89
Author: Eric Anholt <eric at anholt.net>

    intel: improve 2d batchbuffer debug output.

commit 1c8791c581ba2e3906a98a74e998dd51dd474ddb
Author: Eric Anholt <eric at anholt.net>
Date:   Wed Jul 16 10:34:39 2008 -0700

    intel: Fix CopyTexSubImage's src tiling arg for the blit.
    
    Didn't hurt 915, but needed for 965.

commit bdaa06ad639821368ac8d1af7b7561fd7e83fb13

    intel: move renderbuffer mapping to separate functions.
    
    This lets us avoid duplicated code for doing so, including the depthstencil
    paths that aren't covered by SpanRenderStart/Finish.  Those paths were
    missing the span funcs setup, leading to a null dereference in the fbotexture
    demo.
