[Qemu-devel] [PATCH v1 3/4] linux-user/elfload: enable HWCAP_CPUID for A


From: Alex Bennée
Subject: [Qemu-devel] [PATCH v1 3/4] linux-user/elfload: enable HWCAP_CPUID for AArch64
Date: Mon, 28 Jan 2019 17:39:39 +0000

Userspace programs should (in theory) query the ELF HWCAP before
probing these registers. Now we have implemented them all make it
public.
