[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v6 04/19] xen/arm: Implement hypercall DOMCTL_{, un}bind_pt_pirq
From: Julien Grall <julien.grall@xxxxxxxxxx>
On x86, an IRQ is assigned in 2 steps to an HVM guest:
- The toolstack is calling PHYSDEVOP_map_pirq in order to create a
guest PIRQ (IRQ bound to an event channel)
- The emulator (QEMU) is calling DOMCTL_bind_pt_irq in order to
bind the IRQ
On ARM, there is no concept of PIRQ as the IRQ can be assigned to a
virtual IRQ using the interrupt controller.
It's not clear if we will need 2 different hypercalls on ARM to assign
IRQ and, for now, only the toolstack will manage IRQ.
In order to avoid re-using a fixed ABI hypercall (PHYSDEVOP_*) for a
different purpose and allow us more time to figure out the right out,
only DOMCTL_{,un}bind_pt_pirq is implemented on ARM.
The DOMCTL is extended with a new type PT_IRQ_TYPE_SPI and only IRQ ==
vIRQ (i.e machine_irq == spi) is supported.
In order to keep the same XSM checks done by the 2 hypercalls on x86,
call both xsm_map_domain_irq & xsm_bind_pt_irq in the ARM implementation.
Note: The toolstack changes for routing an IRQ to a guest will be done
in a separate patch.

Contrawise PHYSDEV, DOMCTL interface is not fixed. This version is
using a DOMCTL in order to let us more to to see if we need a new
PHYSDEV op for vIRQ assignation.
DOMCTL_unbind_pt_irq has been implemented, although I haven't test
it. I'm not sure if we want to keep it.
xc_domain_{,un}bind_pt_irq are left unchanged because QEMU upstream
& traditional are using them. I will send a follow-up series to drop this 2
functions in order to avoid defering this series while awaiting
changes pushed for QEMU upstream.
Changes in v6:
- Rebase on the latest staging (conflict in xsm/flask/hooks.c
with memaccess changes)
- Remove obsolete paragraph in the commit message
- Fix indentation in libxc
- Don't rely on vspi == spi in xc_domain_{,un}bind_pt_spi_irq
- Typoes in comment
- Add Daniel's ack (XSM part)
Changes in v5:
- Do the check of XSM PHYSDEVOP_map_pirq in the ARM implementation
- Left xc_domain_{,un}bind_pt_irq unchanged
- Introduce xc_domain_{,un}bind_pt_spi_irq
Changes in v4:
- Move the implementation from PHYSDEV to DOMCTL. Reuse
DOMCTL_{,un}bind_pt_irq for this purpose.
Changes in v3:
- Functions to allocate/release/reserved a VIRQ has been moved
in a separate patch
- Make clear that only MAP_PIRQ_GSI is only supported for now
Changes in v2:
- Add PHYSDEVOP_unmap_pirq
- Rework commit message
- Add functions to allocate/release a VIRQ
- is_routable_irq has been renamed into is_assignable_irq
