From dc50165601f5c24b3121defca60d267a980e8dbb Mon Sep 17 00:00:00 2001 From: Karolina Stolarek Date: Wed, 12 Jun 2024 14:02:57 +0200 Subject: [PATCH] drm/ttm/tests: Set DMA mask in KUnit device In commit d393acce7b3f ("drm/tests: Switch to kunit devices"), DRM test helpers migrated away from using a dummy platform driver in favour of KUnit device. This means that DMA masks for the device are not set but are required by ttm_pool_alloc tests. Set the DMA mask for coherent mappings to unblock testing.
