Subject: radeon: use bo_wait to wait for all buffers to be rendered to
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4b9a09e9f63791787fb9a276a4efd685b399be52;p=mesa.git

radeon: use bo_wait to wait for all buffers to be rendered to

Not 100% sure this is correct, but its what Intel does and its better than
CP_IDLE.
