Subject: [PATCH kvmtool v3 3/9] update_headers.sh: arm64: Copy sve_context.h if available
Date: Thu, 30 May 2019 16:13:08 +0100 [thread overview]
Message-ID: <1559229194-3036-4-git-send-email-Dave.Martin@arm.com> (raw)
In-Reply-To: <1559229194-3036-1-git-send-email-Dave.Martin@arm.com>
The SVE KVM support for arm64 includes the additional backend
header <asm/sve_context.h> from <asm/kvm.h>.
So update this header if it is available.
To avoid creating a sudden dependency on a specific minimum kernel
version, ignore the header if the source kernel tree doesn't have
it.
