For the virt board, thesdhci-pci host controller is the only one I saw
supported, so I decided to use that. I didn't see an eMMC device, so I chose
sd-card. I'm hoping that I can create a drive that provides an eMMC image to the
sd-card that will allow me to test my SD host and eMMC drivers. But I don't know
how to create the eMMC image. I read the qemu-img documentation but I'm still
unsure how to do this.
So, my question is, how do I correctly emulate an eMMC on the virt board?
I can't directly help with that question, but your Qemu version is too old to
support eMMC anyway.
According to
https://gitlab.com/qemu-project/qemu/-/commit/e2f346aa98646e84eabe0256f89d08e89b1837cf
you'll have to upgrade to 9.1.0.
Since you seem to be using Debian: unfortunately, bookworm-backports only
contains 9.0.2, just like trixie. Sid, however, does contain 9.1.0, which is
your target version. Another viable option might be to backport the version from
sid to bookworm yourself, but I haven't checked the dependencies to figure out
whether that's easily possible.
