H A D | panfrost_device.h | 92f0ad0b Tue Jun 18 03:16:46 CDT 2019 Boris Brezillon <boris.brezillon@collabora.com> drm/panfrost: Add a module parameter to expose unstable ioctls
We plan to expose performance counters through 2 driver specific ioctls until there's a solution to expose them in a generic way. In order to be able to deprecate those ioctls when this new infrastructure is in place we add an unsafe module parameter that will keep those ioctls hidden unless it's set to true (which also has the effect of tainting the kernel).
All unstable ioctl handlers should use panfrost_unstable_ioctl_check() to check whether they're supposed to handle the request or reject it with ENOSYS.
