[PATCH v2 0/3] disable rings before sync flush

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Naresh Kumar Kachhi <naresh.kumar.kachhi@xxxxxxxxx>

initial version: stop rings before sync flush

v1: address the comments from Chris Wilson on
http://www.spinics.net/lists/intel-gfx/msg41025.html.
Rather than adding stop and start ring, we are moving
ring disable before hw_status_page_setup (sync flush).

v2: Based on Chris's suggestion. Added one more patch to wait
until the rings become idle after disabling. In case of timeout
we log a message.

  drm/i915: disable rings before HW status page setup
  drm/i915: wait for rings to become idle once disabled
  drm/i915: warn if ring is active before sync flush
