Hi all, The change from the last version [1]: * Update the purpose part (patch1) by rewriting the altstack story and having it as the only reason. Thanks Dave Hansen for the feedback. === Cover Letter === When the AMX feature was supported in Linux, the dynamic feature enabling model was introduced. The following documentation changes were considered to help users to adopt this new enabling model: (1) The AMX-enabling code example is expected to clarify the steps. (2) Along with that, a couple of ABI constants may be useful for users. (3) Also, describing the motiviation will provide the context of this. (4) Lastly, the description of new guest options are added as missing. If they are acceptable, the arch_prctl(2) manual page [2] will be followed up separately with something similar to the kernel documentation. These patches can be also found in this repository: git://github.com/intel/amx-linux.git amx-doc And the compiled preview is available here: https://htmlpreview.github.io/?https://github.com/intel/amx-linux/doc-web/x86/xstate.html Thanks, Chang [1] https://lore.kernel.org/lkml/20220909201540.17705-1-chang.seok.bae@xxxxxxxxx/ [2] arch_prctl(2): https://man7.org/linux/man-pages/man2/arch_prctl.2.html Chang S.
