selftests: KVM: Create helper for making SMCCC calls

2022-05-03T20:30:20Z

The PSCI and PV stolen time tests both need to make SMCCC calls within the guest. Create a helper for making SMCCC calls and rework the existing tests to use the library function.

KVM: selftests: aarch64: Add tests for IRQFD in vgic_irq

2021-12-28T19:24:54Z

Add injection tests for the KVM_IRQFD ioctl into vgic_irq. Signed-off-by: Ricardo Koller Acked-by: Andrew Jones Signed-off-by: Marc Zyngier Link: https://lore.kernel.org/r/20211109023906.1091208-16-ricarkol@google.com

KVM: selftests: aarch64: Cmdline arg to set number of IRQs in vgic_irq test

2021-12-28T19:24:06Z

Add the ability to specify the number of vIRQs exposed by KVM (arg defaults to 64). Then extend the KVM_IRQ_LINE test by injecting all available SPIs at once (specified by the nr-irqs arg). As a bonus, inject all SGIs at once as well.

KVM: selftests: arm64: Check for supported page sizes

2021-12-28T11:04:20Z

Just as arm64 implemenations don't necessary support all IPA ranges, they don't all support the same page sizes either. Fun. Create a dummy VM to snapshot the page sizes supported by the host, and filter the supported modes.

KVM: arm64: selftests: Add host support for vGIC

2021-10-17T10:17:21Z

Implement a simple library to perform vGIC-v3 setup from a host point of view. This includes creating a vGIC device, setting up distributor and redistributor attributes, and mapping the guest physical addresses. The definition of REDIST_REGION_ATTR_ADDR is taken from aarch64/vgic_init test. Hence, replace the definition by including vgic.h in the test file.

KVM: arm64: selftests: Add basic GICv3 support

2021-10-17T10:17:21Z

Add basic support for ARM Generic Interrupt Controller v3. The support provides guests to setup interrupts.
