From: Chris Wilson Date: Mon, 11 Feb 2019 13:10:04 +0000 (+0000) Subject: drm/i915: Include the current timeline seqno for debugging execlists X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ed06fddc2203aefb4edbcd179a4e3237e19e6197;p=openwrt%2Fstaging%2Fblogic.git drm/i915: Include the current timeline seqno for debugging execlists While this is mainly only useful for ELSP[0], it is definitely useful to know the current timeline seqno wrt to the queued set of requests for that port, as this carries additional information above and beyond the near-defunct global_seqno and global HWSP.
