[Qemu-devel] [PATCH 11/14] hw/sparc/Kconfig: SPARCstation machine requires the TCX display

[Philippe Mathieu-Daudé]

This is the default display device used in sun4m_hw_init():

    /* If no display specified, default to TCX */

This fixes when configuring with --without-default-devices:

  $ sparc-softmmu/qemu-system-sparc
  qemu-system-sparc: Unknown device 'SUNW,tcx' for default sysbus
  Aborted (core dumped)
