Subject: Re: [PATCH v3 21/23] KVM: s390: arm64: Implement SVE for arm guests
Date: Fri, 06 Nov 2026 20:24:04 +0000 [thread overview]
Message-ID: <sashiko-outbox-202200@kernel.org> (raw)
In-Reply-To: <20261106-sysreg-v3-21-75e95980fb10@linux.ibm.com>
> Add support for Scalable Vector Extension (SVE) in ARM64 guests running
> on s390 hardware, providing 128-bit vector operations backed by s390's
> Vector Extension (VX).
>
> The implementation is limited to 128-bit vectors (VQ=1) matching s390 VX
> register width. Z registers reuse existing FP/SIMD register space (vregs),
> while P registers and FFR are stored in the SAE block.
