+ * all batches secure, allowing them to use any feature with no checking.
+ * This is effectively equivalent to a command parser version of
+ * \infinity - everything is possible.
+ *
+ * The command parser does not exist, and querying the version will
+ * return -EINVAL.
+ *
+ * - v3.16:
+ * The kernel enables the command parser by default, for systems with
+ * aliasing PPGTT enabled (Ivybridge and Haswell). However, the
+ * hardware checker is still enabled, so Haswell and Baytrail cannot
+ * do anything.
+ *
+ * Ivybridge goes from "everything is possible" to "only what the
+ * command parser allows" (if the user boots with i915.cmd_parser=0,
+ * then everything is possible again). We can only safely use features
+ * allowed by the supported command parser version.
+ *
+ * Annoyingly, I915_PARAM_CMD_PARSER_VERSION reports the static version
+ * implemented by the kernel, even if it's turned off. So, checking
+ * for version > 0 does not mean that you can write registers. We have
+ * to try it and see. The version does, however, indicate the age of
+ * the kernel.
+ *
+ * Instead of matching the hardware checker's behavior of converting
+ * privileged commands to MI_NOOP, it makes execbuf2 start returning
+ * -EINVAL, making it dangerous to try and use privileged features.
+ *
+ * Effective command parser versions:
+ * - Haswell: 0 (reporting 1, writes don't work)
+ * - Baytrail: 0 (reporting 1, writes don't work)
+ * - Ivybridge: 1 (enabled) or infinite (disabled)
+ *
+ * - v3.17:
+ * Baytrail aliasing PPGTT is enabled, making it like Ivybridge:
+ * effectively version 1 (enabled) or infinite (disabled).
+ *
+ * - v3.19: f1f55cc0556031c8ee3fe99dae7251e78b9b653b
+ * Command parser v2 supports predicate writes.
+ *
+ * - Haswell: 0 (reporting 1, writes don't work)
+ * - Baytrail: 2 (enabled) or infinite (disabled)
+ * - Ivybridge: 2 (enabled) or infinite (disabled)
+ *
+ * So version >= 2 is enough to know that Ivybridge and Baytrail
+ * will work. Haswell still can't do anything.
+ *
+ * - v4.0: Version 3 happened. Largely not relevant.
+ *
+ * - v4.1: 6702cf16e0ba8b0129f5aa1b6609d4e9c70bc13b
+ * L3 config registers are properly saved and restored as part
+ * of the hardware context. We can approximately detect this point
+ * in time by checking if I915_PARAM_REVISION is recognized - it
+ * landed in a later commit, but in the same release cycle.
+ *
+ * - v4.2: 245054a1fe33c06ad233e0d58a27ec7b64db9284
+ * Command parser finally gains secure batch promotion. On Haswell,
+ * the hardware checker gets disabled, which finally allows it to do
+ * privileged commands.
+ *
+ * I915_PARAM_CMD_PARSER_VERSION reports 3. Effective versions:
+ * - Haswell: 3 (enabled) or 0 (disabled)
+ * - Baytrail: 3 (enabled) or infinite (disabled)
+ * - Ivybridge: 3 (enabled) or infinite (disabled)
+ *
+ * Unfortunately, detecting this point in time is tricky, because
+ * no version bump happened when this important change occurred.
+ * On Haswell, if we can write any register, then the kernel is at
+ * least this new, and we can start trusting the version number.
+ *
+ * - v4.4: 2bbe6bbb0dc94fd4ce287bdac9e1bd184e23057b and
+ * Command parser reaches version 4, allowing access to Haswell
+ * atomic scratch and chicken3 registers. If version >= 4, we know
+ * the kernel is new enough to support privileged features on all
+ * hardware. However, the user might have disabled it...and the
+ * kernel will still report version 4. So we still have to guess
+ * and check.
+ *
+ * - v4.4: 7b9748cb513a6bef4af87b79f0da3ff7e8b56cd8
+ * Command parser v5 whitelists indirect compute shader dispatch
+ * registers, needed for OpenGL 4.3 and later.
+ *
+ * - v4.8:
+ * Command parser v7 lets us use MI_MATH on Haswell.
+ *
+ * Additionally, the kernel begins reporting version 0 when
+ * the command parser is disabled, allowing us to skip the
+ * guess-and-check step on Haswell. Unfortunately, this also
+ * means that we can no longer use it as an indicator of the
