From: Andrii Simiklit Date: Mon, 5 Nov 2018 07:48:26 +0000 (+0200) Subject: i965/batch: avoid reverting batch buffer if saved state is an empty X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b787dcf57b7298868ce9b6885a827d57a6127ba1;p=mesa.git i965/batch: avoid reverting batch buffer if saved state is an empty There's no point reverting to the last saved point if that save point is the empty batch, we will just repeat ourselves. v2: Merge with new commits, changes was minimized, added the 'fixes' tag v3: Added in to patch series v4: Fixed the regression which was introduced by this patch Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=108630 Reported-by: Mark Janes The solution provided by: Jordan Justen CC: Chris Wilson Fixes: 3faf56ffbdeb "intel: Add an interface for saving/restoring the batchbuffer state."
