anv: Flakes in dEQP-VK.api.smoke.*triangle* on bxt_2x6
Recently ChromeOS uprevved the VK CTS to 1.1.5 and enabled more smoke tests including *triangle*
in their pre-merge CI. Since then, we've been seeing flakes on the triangle smoke tests on "coral" devices (broxton 2x6 in celeron N3350 and N3450).
During the time the flakes showed up we were on Mesa 19.0, but I understand they've continued since our update to 20.0.
I don't see flakes in intel ci, assuming I'm searching right, but from irc logs it sounds like intel ci isn't great at distinguishing between 2x6 and 3x6.
Looking around the tree for is_broxton
, I noticed a workaround mentioning 2x6 in gen7_urb.c
that isn't obviously included in anv. Perhaps we need that?
