The code, below, in rdmsr_hypervisor_regs (in xen/arch/x86/traps.c) looks wrong. (The same code is in wrmsr_hypervisor_regs.) int rdmsr_hypervisor_regs( uint32_t idx, uint32_t *eax, uint32_t *edx) { idx -= 0x40000000; if ( idx > 0 ) return 0; ... The intent, apparently, is that the function should return zero if t...

Intercept guest reads of MSR_IA32_MCG_CAP and limit the number of memory banks reported to one. This prevents us from trying to read status of non-existent banks when migrated to a machine with fewer banks.

Hi all, this patch series makes the necessary changes to make sure that the current ARM hypercall ABI can be used as-is on 64 bit ARM platforms: - it defines xen_ulong_t as uint64_t on ARM; - it introduces a new macro to handle guest pointers, called XEN_GUEST_HANDLE_PARAM (that has size 4 bytes on aarch and is going to have size 8 bytes on aarch64); - it replaces all the occurrences of
