Subject: [PATCH] st/dri: do not create a new context for msaa copy
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Commit b77316ad7594f
st/dri: always copy new DRI front and back buffers to corresponding MSAA buffers
introduced creating a pipe_context for every call to validate, which is not required
because the callers have a context anyway.
Only exception is egl_g3d_create_pbuffer_from_client_buffer, can someone test if it
still works with NULL passed as context for validate? From examining the code I
believe it does, but I didn't thoroughly test it.
