From: Jan Luebbe <[email protected]> For testing eMMC-specific functionality (such as handling boot partitions), it would be very useful to attach them to generic VMs such as x86_64 via the sdhci-pci device: ... -drive if=none,id=emmc-drive,file=emmc.img,format=raw \ -device sdhci-pci \ -device emmc,id=emmc0,drive=emmc-drive,boot-partition-size=1048576 \ ...
While most eMMCs are soldered to boards, they can also be connected to SD controllers with just a passive adapter, such as: https://docs.radxa.com/en/accessories/emmc-to-usd https://github.com/voltlog/emmc-wfbga153-microsd The only change necessary to make the options above work is to avoid disabling user_creatable, so do that. The SDHCI-PCI driver in the Linux kernel already supports this just fine.
