From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnout Vandecappelle (Essensium/Mind) Date: Sun, 20 Nov 2016 14:50:06 +0100 Subject: [Buildroot] [PATCH 2/2] kvm-unit-tests: only enable for ARM on Cortex-A7 and A15 In-Reply-To: <20161120135006.19498-1-arnout@mind.be> References: <20161120135006.19498-1-arnout@mind.be> Message-ID: <20161120135006.19498-2-arnout@mind.be> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net The library uses the hypervisor instruction HVC, which is only available on ARMv7-A with Hypervisor extensions. According to [1], this is limited to Cortex-A7 and A15. In addition the build unconditionally passes -marm so it also needs ARM instructions to be available, but that is already implied by the CPU selection. Implicitly fixes http://autobuild.buildroot.net/results/53d109fd9055fd20387bb857aced5f89cf3086fd though it is still not clear why ld doesn't accept the -Ttext=... option there.
