Hi all, This is a continuation of the disabling some hypercalls handling code series. https://lore.kernel.org/xen-devel/20250704092952.822578-1-penny.zh...@amd.com/
It can be beneficial for some dom0less systems to further reduce Xen footprint via disabling some hypercalls handling code, which may not to be used & required in such systems. Each hypercall has a separate option to keep configuration flexible. Options to disable hypercalls: - sysctl - domctl - hvm - physdev - platform_op This is for platform_op. --- cc: Jan Beulich <jbeul...@suse.com> cc: Andrew Cooper <andrew.coop...@citrix.com> cc: "Roger Pau Monné" <roger....@citrix.com> cc: Anthony PERARD <anthony.per...@vates.tech> cc: Michal Orzel <michal.or...@amd.com> cc: Julien Grall <jul...@xen.org> cc: Stefano Stabellini <sstabell...@kernel.org> cc: Lukasz Hawrylko <luk...@hawrylko.pl> cc: "Daniel P.
