This allows to hotplug/unplug PHBs. I could successfully test:
- using in-kernel XICS, emulated XICS and XIVE
- hotplug/unplug with e1000 device to validate LSIs
- hotplug/unplug with virtio-net device to validate MSIs
- some simple migration scenarios
Based on David's ppc-for-4.0 branch SHA1:
6f585625d0d1 target/ppc: Basic POWER9 bare-metal radix MMU support
Please comment.
Changes in v5:
- all DRC subtypes generate FDT fragment at configure connector time
- Drop all the LSI bitmap and allocation/typing disintricate stuff
- set IRQ type in KVM at claim time
- fix hotplug call chain
- added PHB unplug test to tests/device-plug-test
Changes in v4:
- added a LSI bitmap to XICS
- no longer need compat property in XICS
- simplified the patches to access the name and the phandle of the
interrupt controller
- delay the creation of the PHB drc->fdt to RTAS ibm,configure-connector
Change in v3:
- reworked phandle related code some more
- disintricate allocation/"type setting" of interrupts
- identify LSIs at machine init
Changes in v2:
- rebased on current ppc-for-4.0
- added some preliminary cleanup
- call unrealize from realize error path
- advertise PHB hotplug in last patch
- reworked phandle related code
- sync LSIs to KVM
