Subject: [Qemu-devel] [PATCH 00/10] spapr: introduce the 'dual' interrupt mode XICS/XIVE
Date: Wed, 2 Jan 2019 06:57:33 +0100 [thread overview]
Message-ID: <20190102055743.5052-1-clg@kaod.org> (raw)
Hello,
This series adds a new sPAPR IRQ backend called 'dual' which supports
both interrupt mode, the XIVE native exploitation mode and the legacy
compatibility mode (XICS).
The machine operates with the legacy mode by default and lets CAS
negotiate a new interrupt mode. If a new mode is selected, it is
activated after a machine reset to take into account the required
changes. These impact the device tree layout, the interrupt presenter
object and the exposed MMIO regions in the case of XIVE.
The preliminary changes for this new IRQ backend are the introduction
of a second interrupt presenter object under the PowerPCCPU to support
XIVE. The qemu_irq array of each interrupt controller model is also
made common and moved under the machine.

spapr: modify the prototype of the cpu_intc_create() method
ppc/xive: introduce a XiveTCTX pointer under PowerPCCPU
ppc: replace the 'Object *intc' by a 'ICPState *icp' pointer under the
CPU
spapr/xive: simplify the sPAPR IRQ qirq method for XIVE
ppc: export the XICS and XIVE set_irq handlers
pnv/psi: move the ICSState qemu_irq array under the PSI device model
spapr: move the ICSState qemu_irq array under the machine
ppc/xics: allow ICSState to have an offset 0
spapr: introduce a new sPAPR IRQ backend supporting XIVE and XICS
spapr: enable XIVE MMIOs at reset
