Re: [Qemu-devel] which machinetypes have an integrated/implied IDE controller?

[Paolo Bonzini <pbonzini@redhat.com>]

A quick "git grep -l ahci" says that in addition to q35, three ARM
boards have an AHCI controller: highbank, cubieboard (also known as
allwinner-a10) and xilinx-zynq-a9 (also known as xlnx-zynqmp).
Everything else that has IDE really means parallel ATA.

In practice the only difference between the two is that parallel ATA
distinguishes master/slave, while serial ATA has only one unit per bus
(in addition, PATA has two buses while SATA/AHCI has six).

That's not exactly true since g3beige has a PCI controller.  It may well
be that IDE is the only one supported by the firmware.

It's actually called g3beige. :)
