30 * DOC: Hardware workarounds
31 *
32 * Hardware workarounds are register programming documented to be executed in
33 * the driver that fall outside of the normal programming sequences for a
34 * platform. There are some basic categories of workarounds, depending on
35 * how/when they are applied:
36 *
37 * - LRC workarounds: workarounds that touch registers that are
38 * saved/restored to/from the HW context image. The list is emitted (via Load
39 * Register Immediate commands) once when initializing the device and saved in
40 * the default context. That default context is then used on every context
41 * creation to have a "primed golden context", i.e. a context image that
42 * already contains the changes needed to all the registers. See
43 * drivers/gpu/drm/xe/xe_lrc.c for default context handling.
44 *
45 * - Engine workarounds: the list of these WAs is applied whenever the specific
46 * engine is reset. It's also possible that a set of engine classes share a
47 * common power domain and they are reset together. This happens on some
48 * platforms with render and compute engines. In this case (at least) one of
49 * them need to keeep the workaround programming: the approach taken in the
50 * driver is to tie those workarounds to the first compute/render engine that
51 * is registered. When executing with GuC submission, engine resets are
52 * outside of kernel driver control, hence the list of registers involved is
53 * written once, on engine initialization, and then passed to GuC, that
54 * saves/restores their values before/after the reset takes place. See
55 * drivers/gpu/drm/xe/xe_guc_ads.c for reference.
56 *
57 * - GT workarounds: the list of these WAs is applied whenever these registers
58 * revert to their default values: on GPU reset, suspend/resume [1]_, etc.
59 *
60 * - Register whitelist: some workarounds need to be implemented in userspace,
61 * but need to touch privileged registers. The whitelist in the kernel
62 * instructs the hardware to allow the access to happen. From the kernel side,
63 * this is just a special case of a MMIO workaround (as we write the list of
64 * these to/be-whitelisted registers to some special HW registers).
65 *
66 * - Workaround batchbuffers: buffers that get executed automatically by the
67 * hardware on every HW context restore. These buffers are created and
68 * programmed in the default context so the hardware always go through those
69 * programming sequences when switching contexts. The support for workaround
70 * batchbuffers is enabled via these hardware mechanisms:
71 *
72 * #. INDIRECT_CTX (also known as **mid context restore bb**): A batchbuffer
73 * and an offset are provided in the default context, pointing the hardware
74 * to jump to that location when that offset is reached in the context
75 * restore. When a context is being restored, this is executed after the
76 * ring context, in the middle (or beginning) of the engine context image.
77 *
78 * #. BB_PER_CTX_PTR (also known as **post context restore bb**): A
79 * batchbuffer is provided in the default context, pointing the hardware to
80 * a buffer to continue executing after the engine registers are restored
81 * in a context restore sequence.
82 *
83 * Below is the timeline for a context restore sequence:
84 *
85 * .. code::
86 *
87 * INDIRECT_CTX_OFFSET
88 * |----------->|
89 * .------------.------------.-------------.------------.--------------.-----------.
90 * |Ring | Engine | Mid-context | Engine | Post-context | Ring |
91 * |Restore | Restore (1)| BB Restore | Restore (2)| BB Restore | Execution |
92 * `------------'------------'-------------'------------'--------------'-----------'
93 *
94 * - Other/OOB: There are WAs that, due to their nature, cannot be applied from
95 * a central place. Those are peppered around the rest of the code, as needed.
96 * There's a central place to control which workarounds are enabled:
97 * drivers/gpu/drm/xe/xe_wa_oob.rules for GT workarounds and
98 * drivers/gpu/drm/xe/xe_device_wa_oob.rules for device/SoC workarounds.
99 * These files only record which workarounds are enabled: during early device
100 * initialization those rules are evaluated and recorded by the driver. Then
101 * later the driver checks with ``XE_GT_WA()`` and ``XE_DEVICE_WA()`` to
102 * implement them.
103 *
104 * .. [1] Technically, some registers are powercontext saved & restored, so they
105 * survive a suspend/resume. In practice, writing them again is not too
106 * costly and simplifies things, so it's the approach taken in the driver.
107 *
108 * .. note::
109 * Hardware workarounds in xe work the same way as in i915, with the
110 * difference of how they are maintained in the code. In xe it uses the
111 * xe_rtp infrastructure so the workarounds can be kept in tables, following
112 * a more declarative approach rather than procedural.
