Ville Syrjälä	987bcd9a5b	lib: Allow pipe_crc_free(NULL) ... Prevent pipe_crc_free() from segfaulting on NULL ptr. Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com>	2013-10-21 20:00:32 +03:00
Damien Lespiau	768e32a3ab	lib: Don't wait for a vblank when enabling the CRCs ... This was a previous attempt to solve the first CRC being bogus. We know wait for it and discard it at the end of the function. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>	2013-10-18 14:30:53 +01:00
Daniel Vetter	173a4cf1da	tests/debugfs_pipe_crc: fall back to PIPE source ... With PLANE1 and PIPE CRC sources the test will work on all currently shipping (and planed fwiw) platforms. Also add all the other new sources for non-ivb/hsw chips. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>	2013-10-17 13:35:51 +02:00
Damien Lespiau	4ba97ddf96	debugfs_pipe_crc: Let's check CRCs! ... Let's add a new test that sets a mode, wait for a few vblanks (3) and then make sure we read 3 identical CRCs. Some subtests check for various parsing errors. In the process, improve the debugfs helpers to deal with CRCs. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>	2013-10-15 19:40:07 +01:00
