Subject: [PATCH 0/3] drm/i915: add WaIncreaseDefaultTLBEntries
Date: Mon, 25 Jan 2016 14:16:34 +0000 [thread overview]
Message-ID: <1453731397-12877-1-git-send-email-tim.gore@intel.com> (raw)
From: Tim Gore <tim.gore@intel.com>
These 3 patches introduce a performance workaround that
can have significant impact (> 10%) on some OCL workloads.
It is split into 3 patches as follows.
1) The first patch introduces a new function to collect
together workarounds that are GT specific and apply
globally across the GPU (as opposed to per ring or per
context). This function is called at driver load and
on resume (from suspend) and after a GPU reset, so it
can host worarounds that are clobbered by these events.
This new function was suggested by Mika Kuoppala.
2) The second patch adds WaIncreaseDefaultTLBEntries for
gen8 GPU's to the above function.
3) Finally add WaIncreaseDefaultTLBEntries for gen9.
