Description Kenneth Graunke 2019-08-01 02:18:19 UTC 
I would like to land support for CCS_E modifiers in iris before the 19.2 release branches.  Most of the patches have already been written, but are not out for review yet.

We are likely going to need to adjust one of the Gallium APIs for implementing dri_query_image, which I would rather land before the branch point.  I hope to have a proposal for that out shortly.

    iris: Expose aux buffer as 2nd plane w/modifiers
Comment 3 Eero Tamminen 2019-08-14 15:41:19 UTC 
Verified.  At best onscreen write bound synthetic tests improve their perf nearly by 2x (to same level as i965) due to end-to-end render buffer compression working now.
