Subject: [Qemu-devel] [PATCH v2 5/6] linux-user/elfload: enable HWCAP_CPUID for AArch64
Date: Tue, 5 Feb 2019 19:02:23 +0000 [thread overview]
Message-ID: <20190205190224.2198-6-alex.bennee@linaro.org> (raw)
In-Reply-To: <20190205190224.2198-1-alex.bennee@linaro.org>
Userspace programs should (in theory) query the ELF HWCAP before
probing these registers. Now we have implemented them all make it
public.
