Subject: [PATCH v3 04/13] OvmfPkg/MptScsiDxe: Probe PCI devices and look for MptScsi
Date: Wed, 4 Mar 2020 21:22:48 +0200 [thread overview]
Message-ID: <20200304192257.96736-5-nikita.leshchenko@oracle.com> (raw)
In-Reply-To: <20200304192257.96736-1-nikita.leshchenko@oracle.com>
The MptScsiControllerSupported function is called on handles passed in
by the ConnectController() boot service and if the handle is the
lsi53c1030 controller the function would return success. A successful
return value will attach our driver to the device.
