From 1ee72bb55b69796abc69d56a51b8eb3f42438be6 Mon Sep 17 00:00:00 2001 From: Mathieu Othacehe Date: Tue, 20 Aug 2019 18:00:40 +0200 Subject: system: vm: Add arm64 support. * gnu/build/vm.scm (load-in-linux-vm): Add target-arm64? argument and use it to pass correct arguments to qemu. * gnu/system/vm.scm (expression->derivation-in-linux-vm): Pass the new target-arm64? argument added above. Do not add ESP partition on all ARM targets. Do not pass grub-efi package to initialize-hard-disk on ARM targets. --- gnu/build/vm.scm | 19 +++++++++++++------ gnu/system/vm.scm | 15 +++++++++------ 2 files changed, 22 insertions(+), 12 deletions(-) (limited to 'gnu') diff --git a/gnu/build/vm.scm b/gnu/build/vm.scm index b85398ed24..6f920aec9e 100644 --- a/gnu/build/vm.scm +++ b/gnu/build/vm.scm @@ -82,6 +82,7 @@ make-disk-image? single-file-output? target-arm32? + target-aarch64?
