[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v5 p2 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.
Concerning XSM, even if ARM is using one hypercall rather than 2, the
resulting check is nearly the same.
XSM PHYSDEVOP_map_pirq:
1) Check if the current domain can add resource to the domain
2) Check if the current domain has permission to add the IRQ
3) Check if the target domain has permission to use the IRQ
XSM DOMCTL_bind_pirq_irq:
1) Check if the current domain can add resource to the domain
2) Check if the current domain has permission to bind the IRQ
3) Check if the target domain has permission to use the IRQ
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 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
