[Intel-gfx] [i-g-t PATCH v3 3/3] Convert shell script tests to C version
Abdiel Janulgue
abdiel.janulgue at linux.intel.com
Tue Jun 6 08:54:14 UTC 2017
v3: Drop redundant test covered by drv_hangman/basic. Descend thru
debugfs path when reading sysfs entries (Chris).
v2: Use internal igt_debugfs functions instead of cat and document
debugfs tests.
Convert sysfs_l3_parity properly.
Rename redundant names in tests.
Converted:
- check_drm_clients (ensures no other clients are running.
functionality provided by drm_open_driver_master).
- debugfs_emon_crash
- debugfs_wedged
- drv_debugfs_reader
- sysfs_l3_parity
- test_rte_check (same as check_drm_clients)
- tools_test
- ZZ_check_dmesg
