Subject: [intel] assert that buffers are not mapped at last unreference.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9f7d6b72108d9d8bec5f567bcaf33714ffe3ebc2;p=mesa.git

[intel] assert that buffers are not mapped at last unreference.

bufmgr_fake doesn't care about it, but with ttm we would end up with the
buffer remaining referenced until application exit.
