[Qemu-devel] [PATCH] hw/i386/Kconfig: The Q35 machine requires the ICH9_AHCI device

[Philippe Mathieu-Daudé]

The Q35 machine uses the ICH9 chipset which is composed of various
sub-devices. There is currently no generic Kconfig selector that
selects all the required devices. Meanwhile, force the Q35 machine
to select the 'ich9-ahci' device.

This fixes:

  $ ./configure --without-default-devices && \
    ./i386-softmmu/qemu-system-i386 -nodefaults -M q35
  qemu-system-i386: Unknown device 'ich9-ahci' for bus 'PCIE'
  Aborted (core dumped)
