    mesa: _mesa_meta_bitmap() function
Comment 1 Shuang He 2009-09-08 20:40:38 UTC
for OGLC shadow.c, it seems failed when depth texture with format DEPTH_COMPONENT, mode LUMINANCE, compare mode GL_NONE, compare func LEQUAL


for OGLC shadowfuncs.c it seems failed with depth texture with DEPTH_COMPONENT, mode LUMINANCE, compare mode GL_NONE, compare func LESS
Comment 2 Shuang He 2009-09-21 18:41:39 UTC
FYI, those two case passed with following commit, but it may not be the finally resolution:

 [i965] use intel_batchbuffer_flush to flush the clear
Comment 3 Eric Anholt 2010-06-04 15:03:29 UTC
Works on my G45, and I think this was the commit that fixed it.

commit cc8084932cc552587e3036dbbf62c77db3b4a08e

    intel: Flush the batch when we're about to subdata into a VBO.
    
    This fixes the clears in openarena with the new metaops clear code, and
    the new piglit vbo-subdata-sync test.
    
    Bug #23857.
