From 21de5a9e34fb0f3efa31df5712cedc0ae97f7b4d Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 3 Jul 2019 16:52:25 +0100 Subject: [PATCH] drm/i915/gt: Ignore forcewake acquisition for posting_reads We don't care about the result of the read, so it may be garbage, we only care that the mmio is flushed. As such, we can forgo using an individual forcewake and lock around any posting-read for an engine.
