+/** @file drm_lock.c
+ * Implementation of the ioctls and other support code for dealing with the
+ * hardware lock.
+ *
+ * The DRM hardware lock is a shared structure between the kernel and userland.
+ *
+ * On uncontended access where the new context was the last context, the
+ * client may take the lock without dropping down into the kernel, using atomic
+ * compare-and-set.
+ *
+ * If the client finds during compare-and-set that it was not the last owner
+ * of the lock, it calls the DRM lock ioctl, which may sleep waiting for the
+ * lock, and may have side-effects of kernel-managed context switching.
+ *
+ * When the client releases the lock, if the lock is marked as being contended
+ * by another client, then the DRM unlock ioctl is called so that the
+ * contending client may be woken up.
