2025-04-29drm/tests: shmem: Fix memleakMaxime Ripard1-0/+3
The drm_gem_shmem_test_get_pages_sgt() gets a scatter-gather table using the drm_gem_shmem_get_sg_table() function and rightfully calls sg_free_table() on it. However, it's also supposed to kfree() the returned sg_table, but doesn't. This leads to a memory leak, reported by kmemleak. Fix it by adding a kunit action to kfree the sgt when the test ends.

2024-08-02drm/test: fix the gem shmem test to map the sg table.Dave Airlie1-0/+11
The test here creates an sg table, but never maps it, when we get to drm_gem_shmem_free, the helper tries to unmap and this causes warnings on some platforms and debug kernels. This also sets a 64-bit dma mask, as I see an swiotlb warning if I stick with the default 32-bit one.
