Subject: [Qemu-devel] [PATCH v3 0/5] support reading some CPUID/CNT registers from user-space
Date: Mon, 25 Jun 2018 17:00:04 +0100 [thread overview]
Message-ID: <20180625160009.17437-1-alex.bennee@linaro.org> (raw)
Hi,
This expands on the previous version by adding the additional CPUID
registers as exposed by the HWCAP_CPUID kernel feature. Most of the
work involves judicious use of macros. There is a easily extensible
test case that uses the shiny new check-tcg infrastructure ;-)
Alex Bennée (5):
target/arm: support reading of CNT[VCT|FRQ]_EL0 from user-space
target/arm: relax permission checks for HWCAP_CPUID registers
target/arm: expose CPUID registers to userspace
linux-user/elfload: enable HWCAP_CPUID for AArch64
tests/tcg/aarch64: userspace system register test
