mm, treewide: rename MAX_ORDER to MAX_PAGE_ORDER

2024-01-08T23:27:15Z

commit 23baf831a32c ("mm, treewide: redefine MAX_ORDER sanely") has changed the definition of MAX_ORDER to be inclusive. This has caused issues with code that was not yet upstream and depended on the previous definition. To draw attention to the altered meaning of the define, rename MAX_ORDER to MAX_PAGE_ORDER.

mm, treewide: introduce NR_PAGE_ORDERS

2024-01-08T23:27:15Z

NR_PAGE_ORDERS defines the number of page orders supported by the page allocator, ranging from 0 to MAX_ORDER, MAX_ORDER + 1 in total. NR_PAGE_ORDERS assists in defining arrays of page orders and allows for more natural iteration over them.

drm/ttm/tests: Fix type conversion in ttm_pool_test

2023-08-22T11:56:11Z

Fix a warning about casting an integer of different size in ttm_pool_alloc_basic_dma_addr() subtest. Cast the DMA address to uintptr_t before casting it to a generic pointer.

drm/ttm/tests: Add tests for ttm_pool

2023-08-09T16:04:23Z

Add KUnit tests that exercise page allocation using page pools and freeing pages, either by returning them to the pool or freeing them. Add a basic test for ttm_pool cleanup. Introduce helpers to create a dummy ttm_buffer_object.
