[PATCH 0/4] hw/arm/stellaris: QOM/QDev cleanups

Posted by Philippe Mathieu-Daudé 10 months ago

Gustavo wants to access the QOM path of an input IRQ line
from the NVIC, but since the device is orphan he ends up
with this nasty path [*]:

  -device ivshmem-flat,chardev=ivshmem_flat,x-irq-qompath='/machine/unattached/device[1]/nvic/unnamed-gpio-in[0]',x-bus-qompath='/sysbus'

Add the missing parent so the tree is now:

(qemu) info qom-tree
/machine (lm3s6965evb-machine)
  /gamepad (stellaris-gamepad)
  /oled (ssd0323)
  /peripheral (container)
  /peripheral-anon (container)
  /soc (container)
    /v7m (armv7m)
      /cpu (cortex-m3-arm-cpu)
        /unnamed-gpio-in[0] (irq)
        /unnamed-gpio-in[1] (irq)
        /unnamed-gpio-in[2] (irq)
        /unnamed-gpio-in[3] (irq)
      /cpuclk (clock)
      /nvic (armv7m_nvic)
        /NMI[0] (irq)
        /nvic_sysregs[0] (memory-region)
        /systick-trigger[0] (irq)
        /systick-trigger[1] (irq)
        /unnamed-gpio-in[0] (irq)
        ...
