Richard Hughes faa7871b08 Remove duplicate ->probe() calls to speed up startup by 150ms
Now incorporate is fixed to copy across the properties we need in the
superclass, we don't need to do the subclass ->probe().

Note, we still need to do the subclassed ->probe() when using
FU_UDEV_DEVICE_FLAG_VENDOR_FROM_PARENT or when looking at properties
on the parent device.

This also removes the spurious 'already set GType to FuVliUsbhubDevice,
ignoring FuVliUsbhubDevice' messages when running the daemon.

eMMC

Introduction

This plugin reads the sysfs attributes corresponding to eMMC devices. It uses the kernel MMC API for flashing devices.

Protocol

eMMC devices support the org.jedec.mmc protocol.

GUID Generation

These devices use the following instance values:

  • EMMC\%NAME%
  • EMMC\%MANFID%&%OEMID%
  • EMMC\%MANFID%&%OEMID%&%NAME%

Update Behavior

The firmware is deployed when the device is in normal runtime mode, but it is only activated when the device is rebooted.

Vendor ID Security

The vendor ID is set from the EMMC vendor, for example set to EMMC:{$manfid}

External Interface Access

This plugin requires ioctl MMC_IOC_CMD and MMC_IOC_MULTI_CMD access.
