Incorporate a means of detecting submodels of a microarchitecture,
so that different optimizations e.g. block sizes or kernel choices
can be used. The details are as follows:
- Different models are currently only enabled for zen3 and zen4
architectures (for server parts).
- There is a single enumeration (model_t) for all models for all
architectures, but function bli_check_valid_model_id() should
check the provided model_id against the suitable range within
the enumeration for the provided arch_id.
- To enable the model_id to be used within the cntx setup functions,
checking of a user specified value of BLIS_ARCH_TYPE against
the enabled configurations is delayed to a separate function,
bli_arch_check_id().
- Default selection based on hardware can be overridden using the
BLIS_MODEL_TYPE environment variable. Valid values are:
Genoa, Bergamo, Genoa-X, Milan, Milan-X
Values are case-insensitive and -X can also be specified as _X or X
- Specifying an incorrect value for BLIS_MODEL_TYPE is not an error,
but will result in the default option for that architecture being
selected. This is different to specifying an incorrect value of
BLIS_ARCH_TYPE, which is an error.
- The environment variable BLIS_MODEL_TYPE can be renamed using
the --rename-blis-model-type argument to configure (or cmake
equivalent), in a similar way to renaming BLIS_ARCH_TYPE with
--rename-blis-arch-type.
- Configure option --disable-blis-arch-type will disable both
BLIS_ARCH_TYPE and BLIS_MODEL_TYPE environment variables.
- Added code in bli_cpuid.c to detect L1, L2 and L3 cache sizes,
currently only for AMD cpus. Functions are provided to query
these from other parts of the code, namely:
uint32_t bli_cpuid_query_{l1d,l1i,l2,l3}_cache_size()
AMD-Internal: [CPUPL-3033]
