</span>Nice one Jason. With vulkan landing in master I was about to ask you<br>
guys about this (re: reusing isl getting rid of libmesa dependency).<br>
<br>
The size savings sound quite nice. Although it seems that isl might<br>
need a bit more for earlier generations and/or msaa.<br>
<br>
Meanwhile I'll give src/intel, simplifying/folding things a bit.<br>

All you have to do is apply this series and then get rid of the two lines in src/intel/vulkan/Makefile.am that include libmesa and libdri_test_stubs.

A while back I was able to build the "nine" target on freedreno<br>
without a problem. It (used to) include the following:<br>
<br>
$(top_builddir)/src/gallium/auxiliary/<a href="http://libgallium.la" rel="noreferrer" target="_blank">libgallium.la</a> \<br>
$(top_builddir)/src/gallium/state_trackers/nine/<a href="http://libninetracker.la" rel="noreferrer" target="_blank">libninetracker.la</a> \<br>
$(top_builddir)/src/compiler/nir/<a href="http://libnir.la" rel="noreferrer" target="_blank">libnir.la</a> \<br>
$(top_builddir)/src/compiler/<a href="http://libcompiler.la" rel="noreferrer" target="_blank">libcompiler.la</a> \<br>

$(top_builddir)/src/gallium/drivers/freedreno/<a href="http://libfreedreno.la" rel="noreferrer" target="_blank">libfreedreno.la</a> \<br>
+ a bunch of shared libraries<br>
<br>
<br>
Thanks<br>
