I tried to comment out this line:
bo_gem->tiling_mode = set_tiling.tiling_mode;
and now things seem to work. I.e., this statement:
>it overwrites the input arguments following an error in
>order to report the current tiling state of the buffer.
should be false (or, at least, not quite true). This is proved by the fact that
if i undo this part of commit:
- if (ret != 0) {
- *tiling_mode = bo_gem->tiling_mode;
- return -errno;
- }
, i.e. leave 'if' statement in place (and uncomment saving of current
tiling_mode), then things also work, because tiling_mode is not saved on error
now. So, i can conclude that sometimes the kernel doesn't report current tiling
state correctly on error.
