From 44dc9ffbcb89213a9d3e60d00d5d739415ec9adf Mon Sep 17 00:00:00 2001 From: Vasyl Vavrychuk Date: Mon, 5 Oct 2020 08:47:43 +0300 Subject: meta-egvirt, templates: Add virtio-aarch64 machine This machine is intended to run in ARMv8 virtualized environment that provides VirtIO devices. AGL machine configuration files are based on qemuarm64 machine from meta-agl branch master commit e1da0efcd2eece82b0326798cfeaeb8dd48797fc. Yocto machine configuration files are based on qemuarm64 machine from Poky branch dunfell commit 4e931b1d05018923dc145cd97f6f965f5cb6e1a5. Yocto Linux Kernel is used as recommended in [1]. Its metadata for the created machine are based on qemuarm64-standard.scc from yocto-kernel-cache branch yocto-5.4 commit 4aeda12f7f7eb84613ae1fe6e22cd9cd9790c20b. The rationale behind creating new machine is a wish to have a machine that could run on other hypervisor/virtual machine monitor that implements VirtIO, not necessary QEMU. For now, virtio-aarch64 machine runs under QEMU and OpenSynergy COQOS Hypervisor. virtio-aarch64 machine includes following changes comparing to qemuarm64: * use virtio-gpu instead of VGA display (to be upstreamed to work in conjunction with runqemu gl, sdl, etc. options) * use virtio-bus instead of PCI bus QEMU devices * remove unneeded configurations [1]: https://www.yoctoproject.org/docs/3.1.2/bsp-guide/bsp-guide.html#released-bsp-recommendations Bug-AGL: SPEC-3668 Change-Id: Iccfee8613de63770d371a57f0caab1c1eba8d912 Signed-off-by: Vasyl Vavrychuk --- .../linux/linux-yocto/virtio-aarch64/aarch64.cfg | 29 ++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 meta-egvirt/recipes-kernel/linux/linux-yocto/virtio-aarch64/aarch64.cfg (limited to 'meta-egvirt/recipes-kernel/linux/linux-yocto/virtio-aarch64/aarch64.cfg') diff --git a/meta-egvirt/recipes-kernel/linux/linux-yocto/virtio-aarch64/aarch64.cfg b/meta-egvirt/recipes-kernel/linux/linux-yocto/virtio-aarch64/aarch64.cfg new file mode 100644 index 00000000..25381e13 --- /dev/null +++ b/meta-egvirt/recipes-kernel/linux/linux-yocto/virtio-aarch64/aarch64.cfg @@ -0,0 +1,29 @@ +# SPDX-License-Identifier: MIT +# +# ARM64 +# +CONFIG_ARM64=y +CONFIG_64BIT=y + +# +# Bus support +# +CONFIG_ARM_AMBA=y + +# +# Non-8250 serial port support +# +CONFIG_SERIAL_AMBA_PL011=y +CONFIG_SERIAL_AMBA_PL011_CONSOLE=y + +# +# RTC +# +CONFIG_RTC_HCTOSYS=y +CONFIG_RTC_HCTOSYS_DEVICE="rtc0" + +# +# on-CPU RTC drivers +# +CONFIG_RTC_CLASS=y +CONFIG_RTC_DRV_PL031=y -- cgit 1.2.3-korg
