Before this feature, there was only a static on/off switch and the guest had to panic if it was configured in a bad state. The second lets the guest opt in to be able to access the topology CPUID leaves. Before this, accesses to those leaves would #VE. For both of these, it would have been nicest to just change the default behavior, but some pesky "other" OSes evidently need to retain the legacy behavior. Summary: - Add new infrastructure for reading TDX metadata - Use the newly-available metadata to: - Disable potentially nasty #VE exceptions - Get more complete CPU topology information from the VMM" * tag 'x86_tdx_for_6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/tdx: Enable CPU topology enumeration x86/tdx: Dynamically disable SEPT violations from causing #VEs x86/tdx: Rename tdx_parse_tdinfo() to tdx_setup() x86/tdx: Introduce wrappers to read and write TD metadata |
