There are some basic categories of workarounds, depending on + * how/when they are applied: * - * - Workarounds that touch registers that are saved/restored to/from the HW - * context image. The list is emitted (via Load Register Immediate commands) - * everytime a new context is created. - * - GT workarounds. The list of these WAs is applied whenever these registers - * revert to default values (on GPU reset, suspend/resume [2]_, etc..). - * - Display workarounds.

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. * - * .. [1] Please notice that there are other WAs that, due to their nature, - * cannot be applied from a central place. Those are peppered around the rest - * of the code, as needed. + * - 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.

In practice, writing them again is not too - * costly and simplifies things. We can revisit this in the future. + * - 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: * - * Layout - * ~~~~~~ + * #.

Then, inside each type, keep the - * following order: + * #. 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. * - * - Infrastructure functions and macros - * - WAs per platform in standard gen/chrono order - * - Public functions to init or apply the given workaround type. + * - Other: There are WAs that, due to their nature, cannot be applied from a + * central place.
