[PATCH 0/9] drm/tyr: add VM and BO ioctl support

[Ke Sun via B4 Relay <devnull+sunke.kylinos.cn@kernel.org>]

Add the VM and BO ioctls to the Tyr driver, aligning its userspace
interface with panthor. The series is based on Danilo's `drm-file`
series on `drm-rust-next`, and uses the existing IdPool and xarray
abstractions for per-file VM management.

The panthor IGT tests pass on an RK3588S device.
