![]() We were calling g_module_symbol() 2703 times, which is actually more expensive than you'd think. It also means the plugins are actually what we tell people they are: A set of vfuncs that get run. The reality before that they were dlsym'd functions that get called at pretty random times. |

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.
