RH-Commit: [1/1] 60f5385d41269ce9310e1e8e0a2f1106e3a16ada (lvivier/qemu-kvm-centos)

|
|

BZ: https://bugzilla.redhat.com/show_bug.cgi?id=2141965
|
|
|
|
With TPM CRM device, vhost-vdpa reports an error when it tries
|
|
to register a listener for a non aligned memory region:
|
|
|
|
qemu-system-x86_64: vhost_vdpa_listener_region_add received unaligned region
|
|
qemu-system-x86_64: vhost_vdpa_listener_region_del received unaligned region
|
|
|
|
This error can be confusing for the user whereas we only need to skip
|
|
the region (as it's already done after the error_report())
|
|
|
|
Rather than introducing a special case for TPM CRB memory section
|
|
to not display the message in this case, simply replace the
|
|
error_report() by a trace function (with more information, like the
|
|
memory region name).
