[Mesa-dev] [PATCH] i965: Perform program state upload outside of atom handling
Carl Worth

Thu Feb 12 10:25:28 PST 2015
Across the board of the various generations, the intial few atoms in
all of the atom lists are basically the same, (performing uploads for
the various programs). The only difference is that prior to gen6
there's an ff_gs upload in place of the later gs upload.
In this commit, instead of using the atom lists for this program state
upload, we add a new function brw_upload_programs that performs the
same state checks and calls the various upload functions as necessary.
This commit is intended to have no functional change. The motivation
is that future code, (such as the shader cache), wants to have a
single function within which to perform various operations before and
after program upload, (with some local variables holding state across
the upload).
