Hi Bruce,
My Yocto images (which uses the linux-yocto kernel) stopped booting in
QEMU some time ago, and after some debugging it turns out this was
because the upstream Linux kernel removed the legacy IDE driver. Instead
one should use the libata driver. However, I don't think the linux-yocto
kernel has builtin support for the HW that is emulated by QEMU by
default (PIIX), instead it is built as a module, CONFIG_ATA_PIIX=m. If I
set CONFIG_ATA_PIIX=y, my images boot again.
I did a "make ARCH=i386 defconfig" in Torvalds master linux tree, and
the .config has CONFIG_ATA_PIIX=y.
Do you think it would make sense to have the support builtin in
linux-yocto aswell ?
Regards Jacob
