target/i386: Update EPYC-Milan CPU model for Cache property, RAS, SVM feature bits
Found that some of the cache properties are not set correctly for EPYC models. l1d_cache.no_invd_sharing should not be true. l1i_cache.no_invd_sharing should not be true. L2.self_init should be true. L2.inclusive should be true. L3.inclusive should not be true. L3.no_invd_sharing should be true. Fix these cache properties. Also add the missing RAS and SVM features bits on AMD EPYC-Milan model. The SVM feature bits are used in nested guests. succor : Software uncorrectable error containment and recovery capability. overflow-recov : MCA overflow recovery support. lbrv : LBR virtualization tsc-scale : MSR based TSC rate control vmcb-clean : VMCB clean bits flushbyasid : Flush by ASID pause-filter : Pause intercept filter pfthreshold : PAUSE filter threshold v-vmsave-vmload : Virtualized VMLOAD and VMSAVE vgif : Virtualized GIF Signed-off-by: Babu Moger <babu.moger@amd.com> Reviewed-by: Maksim Davydov <davydov-max@yandex-team.ru> Reviewed-by: Zhao Liu <zhao1.liu@intel.com> Link: https://lore.kernel.org/r/c619c0e09a9d5d496819ed48d69181d65f416891.1746734284.git.babu.moger@amd.com Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
