History
Richard Hughes 8ebad4ea75 Specify an enumerated problem when inhibiting devices 
This allows us to make smarter policy decisions in the future on when
to show unavailable updates. It also means we can show translated
text in the frond-end clients.

Only problems the user can "fix" are enumerated. For example, opening
the laptop lid, or charging the device battery.

SCSI

Introduction

This plugin adds support for SCSI storage hardware. Most SCSI devices are enumerated and some UFS devices may also be updatable.

Firmware is sent in 4kB chunks and activated on next reboot only.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in an unspecified binary file format.

This plugin supports the following protocol ID:

  • org.jedec.ufs

GUID Generation

These device use the SCSI DeviceInstanceId values, e.g.

  • SCSI\VEN_HP&DEV_EG0900JETKB&REV_HPD4
  • SCSI\VEN_HP&DEV_EG0900JETKB
  • SCSI\VEN_HP

Vendor ID Security

The vendor ID is set from the vendor, for example set to SCSI:HP

External Interface Access

This plugin requires only reading from sysfs for enumeration, but requires using a sg_io ioctl for UFS updates.
