/**
 * DOC: Hardware workarounds
 *
 * Hardware workarounds are register programming documented to be executed in
 * the driver that fall outside of the normal programming sequences for a
 * platform. There are some basic categories of workarounds, depending on
 * how/when they are applied:
 *
 * - LRC workarounds: workarounds that touch registers that are
 *   saved/restored to/from the HW context image. The list is emitted (via Load
 *   Register Immediate commands) once when initializing the device and saved in
 *   the default context. That default context is then used on every context
 *   creation to have a "primed golden context", i.e. a context image that
 *   already contains the changes needed to all the registers.
 *
 * - Engine workarounds: the list of these WAs is applied whenever the specific
 *   engine is reset. It's also possible that a set of engine classes share a
 *   common power domain and they are reset together. This happens on some
 *   platforms with render and compute engines. In this case (at least) one of
 *   them need to keeep the workaround programming: the approach taken in the
 *   driver is to tie those workarounds to the first compute/render engine that
 *   is registered.  When executing with GuC submission, engine resets are
 *   outside of kernel driver control, hence the list of registers involved in
 *   written once, on engine initialization, and then passed to GuC, that
 *   saves/restores their values before/after the reset takes place. See
 *   ``drivers/gpu/drm/xe/xe_guc_ads.c`` for reference.
 *
 * - GT workarounds: the list of these WAs is applied whenever these registers
 *   revert to their default values: on GPU reset, suspend/resume [1]_, etc.
 *
 * - Register whitelist: some workarounds need to be implemented in userspace,
 *   but need to touch privileged registers. The whitelist in the kernel
 *   instructs the hardware to allow the access to happen. From the kernel side,
 *   this is just a special case of a MMIO workaround (as we write the list of
 *   these to/be-whitelisted registers to some special HW registers).
 *
 * - Workaround batchbuffers: buffers that get executed automatically by the
 *   hardware on every HW context restore. These buffers are created and
 *   programmed in the default context so the hardware always go through those
 *   programming sequences when switching contexts. The support for workaround
 *   batchbuffers is enabled these hardware mechanisms:
 *
 *   #. INDIRECT_CTX: A batchbuffer and an offset are provided in the default
 *      context, pointing the hardware to jump to that location when that offset
 *      is reached in the context restore. Workaround batchbuffer in the driver
 *      currently uses this mechanism for all platforms.
 *
 *   #. BB_PER_CTX_PTR: A batchbuffer is provided in the default context,
 *      pointing the hardware to a buffer to continue executing after the
 *      engine registers are restored in a context restore sequence. This is
 *      currently not used in the driver.
 *
 * - Other/OOB:  There are WAs that, due to their nature, cannot be applied from
 *   a central place. Those are peppered around the rest of the code, as needed.
 *   Workarounds related to the display IP are the main example.
 *
 * .. [1] Technically, some registers are powercontext saved & restored, so they
 *    survive a suspend/resume. In practice, writing them again is not too
 *    costly and simplifies things, so it's the approach taken in the driver.
 *
 * .. note::
 *    Hardware workarounds in xe work the same way as in i915, with the
 *    difference of how they are maintained in the code. In xe it uses the
 *    xe_rtp infrastructure so the workarounds can be kept in tables, following
 *    a more declarative approach rather than procedural.
