From 437c30874cb90537e6275f9ed6f6b88307a906a1 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Fri, 5 Aug 2016 18:11:24 +0200 Subject: [PATCH] drm/i915: Update comment before i915_spin_request ~jiffie and a few usecs is 3 orders of magnitude different. A bit much. This was changed in commit ca5b721e238226af1d767103ac852aeb8e4c0764 Author: Chris Wilson Date: Fri Dec 11 11:32:58 2015 +0000 drm/i915: Limit the busy wait on requests to 5us not 10ms! But probably missed the comment since the change was non-local to the comment. v2: Polish comment more (Chris).
