Subject: [PATCH] kms/dri: add mutex lock around map/unmap
|
||||
|
||||
this can get called from multiple threads with the recent llvmpipe
|
||||
overlapping rendering changes, so make sure to lock around the
|
||||
map/unmapping so they can't race.
|
||||
|
||||
This should fixes some crashes seen with kwin.
