[Mesa-dev] [PATCH v2 0/4] gallium/winsys/kms: Fix issues with prime import

[Tomasz Figa]

Current prime import code in kms-dri Gallium winsys backend has several
issues:
 - It leaks imported buffers, because of duplicate reference count
   increment at import time.
 - It does not check whether an already imported (or local) buffer is not
   being imported, which is problematic because prime import always
   returns the same GEM handle for the same buffer and we end up creating
   duplicate structs referencing the same handle.

This series is an attempt to fix these problems. It originated from
[PATCH] gallium/sw/kms: Fix multiple imports from PRIME FDs
(https://patchwork.freedesktop.org/patch/98856/)
and so they patches inside are considered to be v2.

Tomasz Figa (4):
  gallium/winsys/kms: Fix double refcount when importing from prime FD (v2)
  gallium/winsys/kms: Fully initialize kms_sw_dt at prime import time (v2)
  gallium/winsys/kms: Move display target handle lookup to separate
    function (v2)
  gallium/winsys/kms: Look up the GEM handle after importing a prime FD (v2)
