@g-gupta1 Will need your review on the list of kernel & u-boot patches carried in the PR for xen. |
This recipe is a demonstration for how Xen domains operate. It includes a oneshot script which is ran by systemd. It creates a new domain and tries to ping it. When this script is ran by a DomU it will ping Dom0 i.e, the control domain instead. Signed-off-by: Amneesh Singh <[email protected]>
- tisdk-xen-domu: This is an initramfs based image. This bbappend adds the xen-oob package to the DomU for demonstration purposes. - tisdk-xen-image: This is the base image containing xen and xen-tools, this bbappend adds the xen-oob package as well as installs tisdk-xen-domu as a cpio under /boot so that DomU can use it as root.

This patch adds support to enable Xen for ti-linux-staging. This involves a kernel fragment specifying desired defconfig options as well as two patches: fix-rpmsg-xen.patch: This patch fixes the rpmsg_probe failure that happens otherwise. drivers-...-protocol.patch: This patch [1] is required for compatibility with a patchset [2] for xen which fixes init-dom0less and hotplugging for dom0less domains. [1]: https://lore.kernel.org/xen-devel/[email protected]/ [2]: https://lore.kernel.org/all/alpine.DEB.2.22.394.2405241552240.2557291@ubuntu-linux-20-04-desktop/ Signed-off-by: Amneesh Singh <[email protected]>

This patch provides a custom CONFIG_BOOTCOMMAND when user has enabled xen under DISTRO_FEATURES. This bootcommand runs a script from boot partition, which is boot.scr by default. The script is also provided and is compiled using mkimage as a FIT image. This script loads the Xen image, the kernel image and the FDT and then modifies the FDT to allow suitable Xen configuration and other features like shared memory and UIO.
