Subject: [PATCH 00/10] KVM: arm64: selftests: Introduce arch_timer selftest
Date: Fri, 13 Aug 2021 21:12:01 +0000	[thread overview]
Message-ID: <20210813211211.2983293-1-rananta@google.com> (raw)

Hello,

The patch series adds a KVM selftest to validate the behavior of
ARM's generic timer (patch-10). The test programs the timer IRQs
periodically, and for each interrupt, it validates the behaviour
against the architecture specifications. The test further provides
a command-line interface to configure the number of vCPUs, the
period of the timer, and the number of iterations that the test
has to run for.

Since the test heavily depends on interrupts, the patch series also
adds a basic support for ARM Generic Interrupt Controller v3 (GICv3)
to the KVM's aarch64 selftest framework (patch-9).

Furthermore, additional processor utilities such as accessing the MMIO
(via readl/writel), read/write to assembler unsupported registers,
basic delay generation, enable/disable local IRQs, spinlock support,
and so on, are also introduced that the test/GICv3 takes advantage of.
These are presented in patches 1 through 8.

The patch series, specifically the library support, is derived from the
kvm-unit-tests and the kernel itself.

Regards,
Raghavendra
