Sanjay Yadav bdca18a60e gpu/tests/gpu_buddy: Add gpu_test_buddy_alloc_range for exact-range allocation ... Add a new kunit test gpu_test_buddy_alloc_range() that exercises the __gpu_buddy_alloc_range() exact-range allocation path, triggered when start + size == end with flags=0. The test covers: - Basic exact-range allocation of the full mm - Exact-range allocation of equal sub-ranges (quarters) - Minimum chunk-size exact ranges at start, middle, and end offsets - Non power-of-two mm size with multiple roots, including cross-root exact-range allocation - Randomized exact-range allocations of N contiguous page-aligned slices in random order - Negative: partially allocated range must reject overlapping exact alloc - Negative: checkerboard allocation pattern rejects exact range over partially occupied pairs - Negative: misaligned start, unaligned size, and out-of-bounds end - Free and re-allocate the same exact range across multiple iterations - Various power-of-two exact ranges at natural alignment Cc: Christian König <christian.koenig@amd.com> Cc: Arunpravin Paneer Selvam <Arunpravin.PaneerSelvam@amd.com> Suggested-by: Matthew Auld <matthew.auld@intel.com> Signed-off-by: Sanjay Yadav <sanjay.kumar.yadav@intel.com> Reviewed-by: Matthew Auld <matthew.auld@intel.com> Signed-off-by: Arunpravin Paneer Selvam <Arunpravin.PaneerSelvam@amd.com> Link: https://patch.msgid.link/20260302150947.47535-2-sanjay.kumar.yadav@intel.com		2026-03-09 13:58:12 +05:30
