From dbe65a3796706c85511421612890cce6ac3183e5 Mon Sep 17 00:00:00 2001 From: Jonathan Cavitt Date: Tue, 17 Oct 2023 11:08:05 -0700 Subject: [PATCH] drm/i915/gt: Increase sleep in gt_tlb selftest sanitycheck For the gt_tlb live selftest, when operating on the GSC engine, increase the timeout from 10 ms to 200 ms because the GSC engine is a bit slower than the rest.
