Here's a series of patches to address a crash when mapping multisampled textures in piglit. The crash can easily be reproduce using the following command:
bin/copyteximage 2D -samples=2 -auto However, it's not clear to me if this is the right fix or not; the resource creation code and the resource mapping code is inconsistent in dealing with backing-storage. I decided to go for the widest definition here, but it's possible the narrower one would be more appropriate. The first three patches are smaller cleanups that were noticed while debugging this, and not directly related to the crash. It's also worth mentioning that the test doesn't pass after this either, but at least it doesn't crash. The non-multisample versions of this test doesn't pass either, so I think the failure is unrelated to the presence of backing-store. Dave, what are your thoughts here? It seems you introduced this inconsistency in the very first commit to virgl. Was there some expectation of some third, non-depth handling case here that just didn't get noticed until now?
