Subject: [PATCH v2] MdeModulePkg/ScsiDiskDxe: Update proper device name for ScsiDisk drive
Date: Thu, 27 Oct 2022 07:06:47 +0000 [thread overview]
Message-ID: <57ad249a7bf55fc175b6206ec91c597a969a06d5.1666851664.git.gopic@ami.com> (raw)
ScsiDiskDxe driver updates ControllerNameTable with common string
"SCSI Disk Device" for all SCSI disks. Due to this, when multiple
SCSI disk devices connected, facing difficulty in identifying correct SCSI
disk device. As per SCSI spec, standard Inquiry Data is having the fields
to know Vendor and Product information. Updated "ControllerNameTable" with
Vendor and Product information. So that, device specific name can be
retrieved using ComponentName protocol.
