- Enabled AVX2 TRSM + GEMM kernel path, when GEMM is called from TRSM context it will invoke AVX2 GEMM kernels instead of the default AVX-512 GEMM kernels. - The default context has the block sizes for AVX512 GEMM kernels, however, TRSM uses AVX2 GEMM kernels and they need different block sizes. - Added new API bli_zen4_override_trsm_blkszs(). It overrides default block sizes in context with block sizes needed for AVX2 GEMM kernels. - Added new API bli_zen4_restore_default_blkszs(). It restores The block sizes to there default values (as needed by default AVX512 GEMM kernels). - Updated bli_trsm_front() to override the block sizes in the context needed by TRSM + AVX2 GEMM kernels and restore them to the default values at the end of this function. It is done in bli_trsm_front() so that we override the context before creating different threads. AMD-Internal: [CPUPL-2225] Change-Id: Ie92d0fc40f94a32dfb865fe3771dc14ed7884c55
For more information on sub-configurations and configuration families in BLIS, please read the Configuration Guide, which can be viewed in markdown-rendered form from the BLIS wiki page.
If you don't have time, or are impatient, take a look at the config_registry
file in the top-level directory of the BLIS distribution. It contains a
grammar-like mapping of configuration names, or families, to sub-configurations,
which may be other families. Keep in mind that the / notation:
<config>: <config>/<name>
means that the kernel set associated with <name> should be made available to
the configuration <config> if <config> is targeted at configure-time.
(Some configurations borrow kernels from other configurations, and this is how
we specify that requirement.)
