+ * 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.
