[PATCH] numa: avoid crash with SGX and "info numa" |
Date: |
Wed, 10 Nov 2021 13:29:25 +0100 |
Add the MEMORY_DEVICE_INFO_KIND_SGX_EPC case, so that enclave
memory is included in the output of "info numa" instead of crashing
the monitor.
Fixes: a7c565a941 ("sgx-epc: Add the fill_device_info() callback support",
2021-09-30)
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
