* xen: Remove deltask for setsceneMark Hatle2021-04-291-3/+0
| | | | | | | | | As of the gatesgarth you are no longer allowed to remove setscene tasks as the eSDK generation expects for tasks to actually be executed.

* xen, rpi4: add xen-rpi-u-boot-scr recipe for default u-boot scriptChristopher Clark2021-04-294-17/+36
| | | | | | | | | | | | Add a new xen-rpi-u-boot-scr recipe to PROVIDE u-boot-default-script instead of using a bbappend to rpi-u-boot-scr. This allows the new recipe to be selected by indicating it as PREFERRED_PROVIDER of u-boot-default-script, and then do that in the Xen on Raspberry Pi 4 config file, xen-raspberrypi4-64.inc.

* xen, rpi4: move rpi4-machine+xen-distro cfg into dynamic layerChristopher Clark2021-04-291-0/+23
| | | | | | | | | | | | Improve meta-virt-xen.inc by moving all the Raspberry Pi 4 config settings to a new xen-raspberrypi4-64.inc file in the raspberrypi dynamic layer. The new .inc file is included only for the raspberrypi4-64 MACHINE, so the config settings no longer need to be applied using overrides.

* xen, rpi4: apply workaround to fix crash on boot with Xen 4.14Christopher Clark2021-04-291-0/+3
| | | | | | | | Apply update to the device tree to allow Xen 4.14 to boot. Suggested-by: Bertrand Marquis <bertrand.marquis@arm.com> Signed-off-by: Christopher Clark <christopher.w.clark@gmail.com> Signed-off-by: Bruce Ashfield <bruce.ashfield@gmail.com>
* xen, rpi4: fix u-boot script to load binaries from boot partitionChristopher Clark2021-04-291-2/+5
| | | | | | | | | | | fatload needs to read from mmc 1:1 to find the Xen hypervisor and Linux kernel binaries with the current Yocto Linux 5.10 kernel. Add boot messages to to the u-boot script to indicate the size of files loaded for easier confirmation of load success.

* xen, rpi4, linux-yocto: enable linux-yocto 5.10 for RPi4Christopher Clark2021-04-293-4/+14
| | | | | | | | Added to the raspberrypi dynamic layer for use with Xen as preparation for switching to it as the default preference. Signed-off-by: Christopher Clark <christopher.w.clark@gmail.com> Signed-off-by: Bruce Ashfield <bruce.ashfield@gmail.com>
* xen, rpi4: drop the raspberrypi4-64 defconfig, xen_git.bbappendChristopher Clark2021-04-292-128/+0
| | | | | | | | | Since upstream Xen 4.14 and 4.15 have working default configs for Xen on the Raspberry Pi 4, the defconfig and bbappend in the raspberrypi dynamic layer can now be removed.

* xen, rpi4: use the preferred generic multiboot,module compatible stringChristopher Clark2021-04-291-1/+1
| | | | | | | | This string has been preferred since 2014 -- ref: Xen commit a860dfeec and also current documentation: docs/misc/arm/device-tree/booting.txt Signed-off-by: Christopher Clark <christopher.w.clark@gmail.com> Signed-off-by: Bruce Ashfield <bruce.ashfield@gmail.com>
* xen, linux-yocto-dev, RPi4: weaker assign for KBRANCH and KMACHINEChristopher Clark2020-12-281-2/+2
| | | | | | | | | | Switch to use ?= to set KBRANCH_raspberrypi4-64 to make it easier to override elsewhere when needed for switching to a different kernel branch. Also make the same change for KMACHINE_raspberrypi4-64 to match how it is assigned in the meta-yocto-bsp layer.

* dynamic-layers: add xilinx dynamic layer for Xen supportBruce Ashfield2020-09-223-0/+16
| | | | | | | | | Although this dynamic layer currently only adds Xen support, it will eventually hold other board and platform specific tweaks to core meta-virt recipes. Signed-off-by: Bruce Ashfield <bruce.ashfield@xilinx.com> Signed-off-by: Bruce Ashfield <bruce.ashfield@gmail.com>
* xen, raspi4, linux-yocto-dev: Enable Xen on Raspberry Pi 4Christopher Clark2020-08-111-0/+10
| | | | | | | | | | | Enable linux-yocto-dev as the Linux kernel for Xen on the Raspberry Pi 4, with the bcm-2xxx-rpi4 KMACHINE and KBRANCH. Set a Raspberry Pi SD card variable to increase the size of the boot partition to accommodate both the kernel and the Xen hypervisor.

| | | | | | | | The GIC that is needed by Xen can be enabled via the rpi-config recipe variable. Fixes the build after the upstream recipe changed recently. Signed-off-by: Christopher Clark <christopher.w.clark@gmail.com> Signed-off-by: Bruce Ashfield <bruce.ashfield@gmail.com>
* xen, raspberrypi: bugfix early boot messages: use earlycon=xenbootChristopher Clark2020-08-112-2/+2

* xen, linux-raspberrypi: add Linux kernel 5.4 patches for Xen supportChristopher Clark2020-07-0611-0/+586
| | | | | | | | | | | | | | | | Kernel patches are in process of Linux review and submission, and are backported from the Linux Foundation's Eve Project kernel from 5.6 to 5.4 (some patches not needed for 5.4, hence gaps in the patch sequence number) https://github.com/lf-edge/eve/tree/master/pkg/new-kernel/patches-5.6.x A bbappend applies Xen overrides to the boot command line. Since linux-raspberrypi depends on linux-yocto, and linux-yocto_virtualization introduces a requirement for cfg/virtio.scc obtain it from the yocto kernel cache.

* xen, raspberry pi: add dynamic-layer for Xen configuration for Rpi4Christopher Clark2020-07-063-0/+72
A Xen-specific u-boot script is needed for launching Xen, and the GIC (interrupt controller) needs to be enabled. Since this is both Xen-specific and Raspberry Pi-specific, use a dynamic layer to conditionally enable the recipes when both meta-virtualization and meta-raspberrypi are in use together.
