![]() There is a lot of code in fwupd that just assigns a shared object type to a FuPlugin, and then for each device on that plugin assigns that same shared object to each FuDevice. Rather than proxy several kinds of information stores over two different levels of abstraction create a 'context' which contains the shared *system* state between the daemon, the plugins and the daemon. This will allow us to hold other per-machine state in the future, for instance the system battery level or AC state. |

eMMC Support
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.
