To migrate a VM from a system that supports # GTSE to a system that doesn't, we can boot the guest with # radix_hcall_invalidate=on, thereby forcing the guest to use hcalls for TLB # invalidates. # # The check for hcall availability is done in pSeries_setup_arch so that # the panic message appears on the console. This should only happen on # a hypervisor that doesn't force the guest to hash translation even # though it can't handle the radix GTSE=0 request via CAS. With # radix_hcall_invalidate=on if the hypervisor doesn't support hcall_rpt_invalidate # hcall it should force the LPAR to hash translation. # # Signed-off-by: Aneesh Kumar K.V # Tested-by: Bharata B
