Subject: [RFC kvm-unit-tests 15/27] arm: realm: Add test for FPU/SIMD context save/restore
Date: Fri, 27 Jan 2023 11:40:56 +0000 [thread overview]
Message-ID: <20230127114108.10025-16-joey.gouly@arm.com> (raw)
In-Reply-To: <20230127114108.10025-1-joey.gouly@arm.com>
From: Subhasish Ghosh <subhasish.ghosh@arm.com>
Test that the FPU/SIMD registers are saved and restored correctly when
context switching VCPUs.
In order to test fpu/simd functionality, we need to make sure that
kvm-unit-tests doesn't generate code that uses the fpu registers, as that
might interfere with the test results. Thus make sure we compile the tests
with -mgeneral-regs-only.
