Quoting Zhi Wang (2017-09-14 13:39:43) > Introduce two live tests of private PAT management: > > igt_ppat_init - This test is to check if all the PPAT configurations are > written into HW. > > igt_ppat_get - This test performs several sub-tests on intel_ppat_get() > and intel_ppat_put(). > > The "perfect match" test case will try to get a PPAT entry with an existing > value, then check if the returned PPAT entry is the same one. > > The "alloc entries" test case will run out of PPAT table, and check if all > the requested values are put into the newly allocated PPAT entries. > > The negative test case will try to generate a new PPAT value, and get it > when PPAT table is full. > > The "partial match" test case will generate a parital matched value from > the existing PPAT table and try to match it. > > The "re-alloc" test case will try to free and then allocate a new entry > when the PPAT table is full. > > The "put entries" test case will free all the PPAT entries that allocated > in "alloc entries" test case. It will check if the values of freed PPAT > entries turn into ppat->clear_value. > > v11: > > - Fix one indent problem in v10. > > v10: > > - Refine code structure. > - Introduce "re-alloc" test case. (Chris) > > v9: > > - Refine generate_new_value(). (Chris) > - Refine failure output. (Chris) > - Refine test flow of "perfect match".
