| TODO | |
| ===== | |
| - Add a test case where the only evictable BO is busy | |
| - Update eviction tests so they use parametrized "from" memory type | |
| - Improve mock manager's implementation, e.g. allocate a block of | |
| dummy memory that can be used when testing page mapping functions | |
| - Suggestion: Add test cases with external BOs | |
| - Suggestion: randomize the number and size of tested buffers in | |
| ttm_bo_validate() | |
| - Agree on the naming convention | |
| - Rewrite the mock manager: drop use_tt and manage mock memory using | |
| drm_mm manager | |
| Notes and gotchas | |
| ================= | |
| - These tests are built and run with a UML kernel, because | |
| 1) We are interested in hardware-independent testing | |
| 2) We don't want to have actual DRM devices interacting with TTM | |
| at the same time as the test one. Getting these to work in | |
| parallel would require some time (...and that's a "todo" in itself!) | |
| - Triggering ttm_bo_vm_ops callbacks from KUnit (i.e. kernel) might be | |
| a challenge, but is worth trying. Look at selftests like | |
| i915/gem/selftests/i915_gem_mman.c for inspiration | |
| - The test suite uses UML where ioremap() call returns NULL, meaning that | |
| ttm_bo_ioremap() can't be tested, unless we find a way to stub it |
