+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
+
+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
List improvements for the test suite with some notes. Signed-off-by: Karolina Stolarek <karolina.stolarek@intel.com> --- drivers/gpu/drm/ttm/tests/TODO | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 drivers/gpu/drm/ttm/tests/TODO
