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. */ #undef XE_REG_MCR #define XE_REG_MCR(...)
