Details: - pack and compute extension APIs derive blocksizes(MR, NR...) from SUP cntx. - SUP blocksizes are not set for generic/skx configs. As a result pack and compute APIs cause floating point exceptions. - To fix these issues, we have enabled non-zero SUP blocksizes for generic config and zen4 SUP blocksizes for skx config. - However, these changes will not enable SUP path for skx/generic config as thresholds are set to zero. - To enable SUP path for skx config, more work is needed like non-zero thresholds and modifications to build system.

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.)
