After a bit of digging into this n_words conundrum that I also could not understand, I found the issue Mika described. kms_plane_multiple et al basically do igt_crc_t crc; and then they pass &crc to test-internal helper functions, which pass the igt_crc_t* pointer to various igt lib functions. The problem is, those lib functions take igt_crc_t** so that they can give you the correct pointer, kms_plane* wrongly expect them to modify the passed object. Mika, can you fix this while you're at it? -- Petri Latvala _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
