Detailed Description

struct drm_panthor_set_user_mmio_offset - Arguments passed to DRM_IOCTL_PANTHOR_SET_USER_MMIO_OFFSET

This ioctl is only really useful if you want to support userspace CPU emulation environments where the size of an unsigned long differs between the host and the guest architectures.

__u64 drm_panthor_set_user_mmio_offset::offset

@offset: User MMIO offset to use.

Must be either DRM_PANTHOR_USER_MMIO_OFFSET_32BIT or DRM_PANTHOR_USER_MMIO_OFFSET_64BIT.

Use DRM_PANTHOR_USER_MMIO_OFFSET (which selects OFFSET_32BIT or OFFSET_64BIT based on the size of an unsigned long) unless you have a very good reason to overrule this decision.
