+Subject: [PATCH] Revert require GL_EXT_unpack_subimage commit
+
+This reverts commit 593d5af43a8e2c2a3371088fa7ae430d0517c82d.
+
+That commit removed support for GPU drivers without GL_EXT_unpack_subimage
+which SGX does not support. Add back support for GPUs without this
+extension.
The obvious question - how safe is it to assume GL_EXT_unpack_subimage is
not being used some place else outside of this commit and not guarded by:
if (!gr->has_unpack_subimage)
Is this extention really in the driver, or just in a Mesa API translation
layer? Could it be better fixed in the DDK?
You are right, it is not a very safe assumption, this patch is almost certainly
not complete for all cases. And even if it was, it only fixes Weston, others
like
wlroots have the same issues[0], so other compositors are going to be broken
too.
Long term this extension will need added to the driver. Unfortunately all work
on
keeping this driver alive is unofficial, and I just don't have the free time to
add and test new extensions right now :(
