While debugging the libdrm duplicate buffer object adventure, I managed to
temporarily understand object lifetimes in the __DRIimage getBuffers path, and
also to compare that to the DRI2 getBuffers path. Here are a couple of small
fixes.
I haven't looked at the i915 code, but I suspect the first one, and parts of
the second one would apply.
[PATCH 1/2] i965: Correct check for re-bound buffer in
The code was attempting to avoid re-creating the miptree when the loader
handed back the same bufffer we already had, but it was confused about how to
tell -- turns out the object actually shared between the loader and the driver
is the BO, not the region. And so, we compare BO pointers to see if the image
buffer needs to have a new miptree.
[PATCH 2/2] i965: Set fast color clear mcs_state on newly allocated
Here's a chunk of code that was just missing from the __DRIimage path as a
result of rebasing across some new driver additions.
Both of these fixes are candidates for 10.0 as they affect the __DRIimage
paths now used by Wayland.
For future reference, patches that are candidates for the latest stable branch should include the line
in the patch. (see http://lists.freedesktop.org/archives/mesa-dev/2013-August/042667.html)
I've forwarded this email to mesa-stable@xxxxxxxxxxxxxxxxxxxxx, which should also be sufficient.
