2522 * \infinity - everything is possible.
2524 * The command parser does not exist, and querying the version will
2528 * The kernel enables the command parser by default, for systems with
2529 * aliasing PPGTT enabled (Ivybridge and Haswell). However, the
2530 * hardware checker is still enabled, so Haswell and Baytrail cannot
2533 * Ivybridge goes from "everything is possible" to "only what the
2534 * command parser allows" (if the user boots with i915.cmd_parser=0,
2535 * then everything is possible again). We can only safely use features
2536 * allowed by the supported command parser version.
2538 * Annoyingly, I915_PARAM_CMD_PARSER_VERSION reports the static version
2539 * implemented by the kernel, even if it's turned off. So, checking
2540 * for version > 0 does not mean that you can write registers. We have
2541 * to try it and see. The version does, however, indicate the age of
2544 * Instead of matching the hardware checker's behavior of converting
2545 * privileged commands to MI_NOOP, it makes execbuf2 start returning
2546 * -EINVAL, making it dangerous to try and use privileged features.
2548 * Effective command parser versions:
2549 * - Haswell: 0 (reporting 1, writes don't work)
2550 * - Baytrail: 0 (reporting 1, writes don't work)
2551 * - Ivybridge: 1 (enabled) or infinite (disabled)
2554 * Baytrail aliasing PPGTT is enabled, making it like Ivybridge:
2555 * effectively version 1 (enabled) or infinite (disabled).
2557 * - v3.19: f1f55cc0556031c8ee3fe99dae7251e78b9b653b
2558 * Command parser v2 supports predicate writes.
2560 * - Haswell: 0 (reporting 1, writes don't work)
2561 * - Baytrail: 2 (enabled) or infinite (disabled)
2562 * - Ivybridge: 2 (enabled) or infinite (disabled)
2564 * So version >= 2 is enough to know that Ivybridge and Baytrail
2565 * will work. Haswell still can't do anything.
2567 * - v4.0: Version 3 happened. Largely not relevant.
2569 * - v4.1: 6702cf16e0ba8b0129f5aa1b6609d4e9c70bc13b
2570 * L3 config registers are properly saved and restored as part
2571 * of the hardware context. We can approximately detect this point
2572 * in time by checking if I915_PARAM_REVISION is recognized - it
2573 * landed in a later commit, but in the same release cycle.
2575 * - v4.2: 245054a1fe33c06ad233e0d58a27ec7b64db9284
2576 * Command parser finally gains secure batch promotion. On Haswell,
2577 * the hardware checker gets disabled, which finally allows it to do
2578 * privileged commands.
2580 * I915_PARAM_CMD_PARSER_VERSION reports 3. Effective versions:
2581 * - Haswell: 3 (enabled) or 0 (disabled)
2582 * - Baytrail: 3 (enabled) or infinite (disabled)
2583 * - Ivybridge: 3 (enabled) or infinite (disabled)
2585 * Unfortunately, detecting this point in time is tricky, because
2586 * no version bump happened when this important change occurred.
2587 * On Haswell, if we can write any register, then the kernel is at
2588 * least this new, and we can start trusting the version number.
2590 * - v4.4: 2bbe6bbb0dc94fd4ce287bdac9e1bd184e23057b and
2591 * Command parser reaches version 4, allowing access to Haswell
2592 * atomic scratch and chicken3 registers. If version >= 4, we know
2593 * the kernel is new enough to support privileged features on all
2594 * hardware. However, the user might have disabled it...and the
2595 * kernel will still report version 4. So we still have to guess
2598 * - v4.4: 7b9748cb513a6bef4af87b79f0da3ff7e8b56cd8
2599 * Command parser v5 whitelists indirect compute shader dispatch
2600 * registers, needed for OpenGL 4.3 and later.
2603 * Command parser v7 lets us use MI_MATH on Haswell.
2605 * Additionally, the kernel begins reporting version 0 when
2606 * the command parser is disabled, allowing us to skip the
2607 * guess-and-check step on Haswell. Unfortunately, this also
2608 * means that we can no longer use it as an indicator of the
2609 * age of the kernel.
