- TRSM and GEMM has different blocksizes in zen4, in order to accommodate this, a local copy of cntx was created in TRSM. - Local copy of cntx has been removed and TRSM blocksizes are stored in cntx->trsmblkszs. - Functions to override and restore default blocksizes for TRSM are removed. Instead of overriding the default blocksizes, TRSM blocksizes are stored separately in cntx. - Pack buffers for TRSM have to be packed with TRSM blocksizes and GEMM pack buffers have to be packed with default blocksizes. To check if we are packing for TRSM, "family" argument is added in bli_packm_init_pack function. - BLIS_GEMM_FOR_TRSM_UKR has to be used for TRSM if it is set, if it is not set then BLIS_GEMM_UKR has to be used. This functionality has been added to all TRSM macro kernels. - Methods to retrieve TRSM blocksizes from cntx are added to bli_cntx.h. - Tests for micro kernels are modified to accommodate the change in signature of bli_packm_init_pack.

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.)
