Struct drm_sys::drm_hw_lock

#[repr(C)]
pub struct drm_hw_lock {
    pub lock: c_uint,
    pub padding: [c_char; 60],
}

Hardware lock.

The lock structure is a simple cache-line aligned integer. To avoid processor bus contention on a multiprocessor system, there should not be any other data stored in the same cache line.

Fields
