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
