From 5b9afc161ea595c82707f5f9d67c96a00a8bcbae Mon Sep 17 00:00:00 2001 From: Alyssa Rosenzweig Date: Wed, 25 May 2022 10:57:51 -0400 Subject: [PATCH] drm/panfrost: Add "clean only safe" feature bit Add the HW_FEATURE_CLEAN_ONLY_SAFE bit based on kbase. When I actually tried to port the logic from kbase, trivial jobs raised Data Invalid Faults, so this may depend on other coherency details. It's still useful to have the bit to record the feature bit when adding new models.
