+arm-autonomy Multiconfig Build Environment Instructions
+==================
+
+This documentation explains how to simplify the process of building hosts
+and guests in a single bitbake command, rather than in seperate build
+folders. You can read more about multiconfig in the bitbake documentation:
+
+ - [bitbake user manual](https://www.yoctoproject.org/docs/latest/bitbake-user-manual/bitbake-user-manual.html)
+
+To achieve a multiconfig build, a number of different config files need to
+be created in a single build directory.
+
+Create a new project
+----------------
+
+Before you start, you will need to follow the instructions in
+"Create a project" from the quickstart guide, to create a new project
+directory with
+  ```
+  oe-init-build-env my-mc-project
+  ```
+Ensure it has all the required layers in bblayers.conf as listed in
+`arm-autonomy-quickstart.md`. The result should be a directory containing:
+
+```
+-- conf
+ | -- bblayers.conf
+ | -- local.conf
+ | -- templateconf.cfg
+```
+
+Add multiconfig
+----------------
+
+Here are the steps required to make the project build both the host and any
+number of guests as required.
+
+1. Create a new directory under `conf/` named `multiconfig/`
+
+2. Create two new files in this directory:
+`multiconfig/host.conf`
+`multiconfig/guest.conf`
+These files will contain any configurations that a specific to either the
+host or the guest
+
+```
+-- conf
+ | -- bblayers.conf
+ | -- local.conf
+ | -- templateconf.cfg
+ | -- multiconfig
+    | -- host.conf
+    | -- guest.conf
+```
+
+3. In `local.conf` the following config variables must be added:
+
+```
+MACHINE ?= "fvp-base"
+
+# ---Guest Config Start--- #
+MC_GUEST = "guest"
+
+MC_GUEST_NAME = "guest1"
+
+MC_GUEST_IMAGERECIPE = "core-image-minimal"
+MC_GUEST_MACHINE = "arm64-autonomy-guest"
+
+MC_GUEST_INITRAMFS_IMAGE_BUNDLE ?= ""
+MC_GUEST_INITRAMFS_IMAGE ?= ""
+
+# Uncomment for initramfs
+#MC_GUEST_INITRAMFS_IMAGE_BUNDLE = "1"
+#MC_GUEST_INITRAMFS_IMAGE = "${MC_GUEST_IMAGERECIPE}"
+
+# These variables are set automatically, don't edit them!
+MC_GUEST_FILENAME_PREFIX = "${@ 'Image-initramfs' if d.getVar('MC_GUEST_INITRAMFS_IMAGE_BUNDLE',d) else '${MC_GUEST_IMAGERECIPE}' }"
+
+MC_GUEST_FILENAME = "${MC_GUEST_FILENAME_PREFIX}-${MC_GUEST_MACHINE}.xenguest"
+
+MC_GUEST_DEP = "${@ 'virtual/kernel:do_deploy' if d.getVar('MC_GUEST_INITRAMFS_IMAGE_BUNDLE',d) else '${MC_GUEST_IMAGERECIPE}:do_image_complete'}"
+
+MC_DOIMAGE_MCDEPENDS += "mc:${MC_HOST}:${MC_GUEST}:${MC_GUEST_DEP} "
+
+BBMULTICONFIG += "${MC_GUEST} "
+
+ARM_AUTONOMY_HOST_IMAGE_EXTERN_GUESTS += "file://${TOPDIR}/${MC_GUEST}/deploy/images/${MC_GUEST_MACHINE}/${MC_GUEST_FILENAME};guestname=${MC_GUEST_NAME} "
+# ---Guest Config End--- #
+
+# ---Host Config Start--- #
+MC_HOST = "host"
+
+BBMULTICONFIG += "${MC_HOST} "
+# ---Host Config End--- #
+```
+
+These variables will be used in both of the multiconf files. `MC_HOST` and
+`MC_GUEST` should not be altered without renaming the conf files, but most
+`MC_GUEST_*` variables can be customised if you desire.
+
+4. Next set the contents of `multiconfig/guest.conf`:
+
+```
+TMPDIR = "${TOPDIR}/${MC_GUEST}"
+
+MACHINE = "${MC_GUEST_MACHINE}"
+DISTRO_FEATURES += " arm-autonomy-guest"
+
+INITRAMFS_IMAGE_BUNDLE = "${MC_GUEST_INITRAMFS_IMAGE_BUNDLE}"
+INITRAMFS_IMAGE = "${MC_GUEST_INITRAMFS_IMAGE}"
+
+IMAGE_FSTYPES += "${@ 'cpio' if d.getVar('MC_GUEST_INITRAMFS_IMAGE_BUNDLE',d) else ''}"
+
+# ANY OTHER GUEST CONFIG
+```
+
+This contents shouldn't be changed directly, rather change the equivalent
+config in local.conf. You can append any other config desired for the
+guest at this point, for example `XENGUEST_IMAGE_DISK_SIZE`
+
+Make sure not to change `${DEPLOY_DIR_IMAGE}` to anything other than
+`${TMPDIR}/deploy/images`, as this is assumed by local.conf.
+
+5. Lastly set the contents of `multiconfig/host.conf`:
+
+```
+TMPDIR = "${TOPDIR}/${MC_HOST}"
+
+DISTRO_FEATURES += " arm-autonomy-host"
+```
+
+Building the image
+----------------
+
+To build the multiconfig image the command is:
+```
+bitbake mc:host:arm-autonomy-host-image-minimal
+```
+
+You should see that this triggers guest tasks to be built in
+parallel. Once the build completes the guest will already be in the
+rootfs of the host thanks to `ARM_AUTONOMY_HOST_IMAGE_EXTERN_GUEST`
+
+The deployed image including the guest will be in `host/deploy/images/`
+
+
+Multiple Guests
+----------------
+
+To have multiple guests with the same config the line which appends to
+`ARM_AUTONOMY_HOST_IMAGE_EXTERN_GUEST` just needs to be duplicated with
+a different guestname.
+
+To have different config for each guest, each will need its own config
+file similar to guest.conf, ensuring TMPDIR is set to a different path,
+and everything between `---Guest Config Start---` and
+`---Guest Config End---` will need to be duplicated.
+
+Any copies of variables that start `MC_GUEST` must be altered to avoid
+collisions (e.g. `MC_GUEST_2_*`), and the name of the conf file must also
+be added to BBMULTICONFIG.
+
+
+Guest with provisioned disk
+----------------
+
+To add guest rootfs partition to host wic image,
+set `AUTONOMY_HOST_EXTRA_PARTITION` with proper wks partition entry, e.g:
+
+```
+AUTONOMY_HOST_EXTRA_PARTITION = "part --label provisioned-guest --source rawcopy --fstype=ext4 --ondisk sda --align 1024 \
+--sourceparams=file=${TOPDIR}/${MC_GUEST}/deploy/images/${MC_GUEST_MACHINE}/${MC_GUEST_FILENAME_PREFIX}-${MC_GUEST_MACHINE}.ext4"
+```
+
+inside host.conf file.
+
+The rest of the configuration has to be appended to guest.conf file:
+
+```
+XENGUEST_IMAGE_DISK_SIZE = "0"
+XENGUEST_IMAGE_SRC_URI_XEN_CONFIG = "file://\${TOPDIR}/path/to/rootdisk.cfg"
+XENGUEST_IMAGE_DISK_DEVICE = "_GUEST_DISK_DEVICE_"
+XENGUEST_IMAGE_ROOT = "/dev/xvda"
+IMAGE_ROOTFS_SIZE = "102400"
+IMAGE_FSTYPES = "ext4"
+```
+
+content of rootdisk.cfg"
+
+```
+disk = ["phy:_GUEST_DISK_DEVICE_,xvda,w"]
+```
+
+`_GUEST_DISK_DEVICE_` should be substituted with `/dev/sdaX`,
+according to wks file.

+Customizing Arm Autonomy Host image layout for N1SDP
+====================================================
+
+When buiding with `DISTRO_FEATURES += "arm-autonomy-host"` the user can
+perform a couple of customizations in the generated wic image:
+
+1. Set the guest partition size (default: 4iG) via `GUEST_PART_SIZE` and
+   `GUEST_PART_SIZE_UNIT` (M or G) variables to be set in any conf file. The
+   value of these variables should be aligned with the sum of all
+   XENGUEST_IMAGE_DISK_SIZE set for the guests. By default, LVM2 metadata is
+   1 MiB per physical volume, hence it needs to be taken into account when
+   setting GUEST_PART_SIZE.
+
+2. Set the boot partition size (default: 100M) via `BOOT_PART_SIZE` and
+   `BOOT_PART_SIZE_UNIT` (M or G) variables in any conf file. The default
+   bootimg is ~44M so 100M leaves just over 50M of free space.

+3. The wic image partition layout and contents with a custom wks file via
+   `ARM_AUTONOMY_WKS_FILE` variable (default:
+   arm-autonomy-n1sdp-efidisk.wks.in which is affected by GUEST_PART_SIZE,
+   GUEST_PART_SIZE_UNIT, BOOT_PART_SIZE, BOOT_PART_SIZE_UNIT and
+   GRUB_CFG_FILE variables).
+
+4. Custom grub.cfg file via `GRUB_CFG_FILE` (default:
+   arm-autonomy-n1sdp-grub.cfg) variable to be set in any conf file. The full
+   path or relative to `ARM_AUTONOMY_WKS_FILE` should be set.

+The `arm-autonomy-n1sdp-efidisk.wks.in` and `arm-autonomy-n1sdp-grub.cfg` files
+are located at `meta-arm-autonomy/dynamic-layers/meta-arm-bsp/wic`.

-xenguest network bridge
-=======================
-
-Introduction
-------------
-
-xenguest-network-bridge is creating a network bridge to allow some guests to
-have a direct connection to the external network.
-To do this, a bridge is created on the host using brctl with the network
-interfaces added to it so that the bridge is connected to the external network.
-It is also adding a guest init script which will, for guests configured to use
-it, create a virtual network interface for the guest and connect it to the
-network bridge on the host.
-
-Usage
------
-
-On the host the package xenguest-network-bridge must be included in your image.
-
-On the xenguest image of your guest, the parameter NETWORK_BRIDGE must be set
-to 1 (using xenguest-mkimage --set-param=NETWORK_BRIDGE=1).
-
-Bitbake parameters
-------------------
-Several parameters are available to configure the xenguest network bridge
-during Yocto project compilation (those can be set in your project local.conf,
-for example).
-
-The following parameters are available:
-
-- XENGUEST_NETWORK_BRIDGE_NAME: This variable defines the name of the network
-  bridge that is created on the host during init.

+Xenguest Network
+================
+
+Introduction
+------------
+
+The xenguest-network package is primarly creating a network bridge to share
+the host eth physical interfaces with the guests virtual interfaces (vif).
+This way the guests can have access to the external network.
+
+At the moment 3 types of network arrangements are provided:
+
+- Bridge: where the guest vif is added to the created bridge interface;
+
+- NAT: where a private subnet is created for the guest,
+  a kea dhcp4 server is started on the host to serve the guest
+  and the proper iptables rules are created
+  to allow the guest to access the external network;
+
+- None: the guest vif is not connected to the bridge.
+
+Usage
+-----
+
+On the host project the package xenguest-network must be included in your
+image, and on the guest project the XENGUEST_NETWORK_TYPE needs to be set to
+"bridge", "nat" or "none".
+
+Bitbake parameters
+------------------
+
+Several parameters are available to configure the xenguest network bridge
+during Yocto project compilation (those can be set in your project local.conf
+or xenguest-network.bbappend, for example).
+
+The following parameters are available:
+
+- XENGUEST_NETWORK_BRIDGE_NAME: This variable defines the name of the network
+  bridge that is created on the host during init.
+  This is set by default to "xenbr0".
+
+- XENGUEST_NETWORK_BRIDGE_MEMBERS: This variable defines the list of the
+  physical network interfaces that are added to the bridge when it is created
+  on the host during init.
+  By default no physical interfaces are added.
+
+- XENGUEST_NETWORK_BRIDGE_CONFIG: This variable defines the configuration file
+  to use to configure the bridge network. By default it points to have file
+  configuring the network using dhcp.
+  You can provide a different file using a bbappend and make this variable
+  point to it if you want to customize your network configuration.
+
+- XENGUEST_IMAGE_NETWORK_TYPE: This variable can be set to "bridge" (default),
+  "nat" or "none".
+  The **bridge** type will add the domU vif interface to a bridge which also
+  contains the dom0 physical interface giving the guest direct access to the
+  external network.
+  The **nat** type will setup a private network between dom0 and domU, setup
+  the appropriate routing table, configure and run the kea dhcp4 server
+  on dom0 to serve the domU and apply the iptables rules to allow the guest
+  to acess the external network. The kea dhcp4 server configuration for
+  the guest can be customised by replacing the
+  "meta-arm-autonomy/recipes-extended/xenguest/files/kea-subnet4.json" file
+  in a xenguest-network.bbappend. The kea-subnet4.json file is installed in
+  the xenguest image and copied to
+  "/etc/xenguest/guests/${guestname}/files/kea-subnet4.json" when the guest
+  image is created. It will be consumed by the
+  "/etc/xen/scripts/vif-post.d/00-vif-xenguest.hook" script which is called by
+  "/etc/xen/scripts/vif-nat" script when starting/stopping the xenguest.
+  After guest start, "/etc/xenguest/init.post/xenguest-network-init-post.sh"
+  script is called to reload kea dhcp4 server with updated configuration,
+  after virtual network interface is ready.
+  In the guest project, the NAT port forward can be customised by changing
+  the XENGUEST_IMAGE_HOST_PORT (default: "1000 + ${domid}") and
+  XENGUEST_IMAGE_GUEST_PORT (default: "22") variables in local.conf or
+  xenguest-base-image.bbappend. This configuration is implemented and installed
+  in "/etc/xenguest/guests/${guestname}/files/00-xenguest-nat-port-forward.hook"
+  script which is called by "/etc/xen/scripts/vif-post.d/00-vif-xenguest.hook".
+  The **none** type will not affect any networking setting between on dom0 and
+  domU.

-Subject: [PATCH] xen/arm: Cap the number of interrupt lines for dom0
-
-Dom0 vGIC will use the same number of interrupt lines as the hardware GIC.
-While the hardware GIC can support up to 1020 interrupt lines,
-the vGIC is only supporting up to 992 interrupt lines.
-This means that Xen will not be able to boot on platforms where the hardware
-GIC supports more than 992 interrupt lines.
-While it would make sense to increase the limits in the vGICs, this is not
-trivial because of the design choices.
-At the moment, only models seem to report the maximum of interrupt lines.
-They also do not have any interrupt wired above the 992 limit.
-So it should be fine to cap the number of interrupt lines for dom0 to 992 lines.

+Subject: [PATCH] xen: use handle_fasteoi_irq to handle xen dynamic events
+
+When handling Xen events, we need to make sure the following sequence is
+followed:
+
+- mask event
+- handle event and clear event (the order does not matter)
+- unmask event
+
+It is not possible to implement this flow with handle_edge_irq, so
+switch back to handle_fasteoi_irq. Please note that Xen event irqs are
+ONESHOT. Also note that handle_fasteoi_irq was in-use before the
+following commit, that is partially reverted by this patch:
+
+7e186bdd0098 xen: do not clear and mask evtchns in __xen_evtchn_do_upcall
+
+PIRQ handling is left unchanged.
+
+This patch fixes a domU hang observed when using LinuxRT as dom0 kernel.

+Subject: [PATCH] xen/arm: Missing N1/A76/A75 FP registers in vCPU context
+ switch
+
+Xen has cpu_has_fp/cpu_has_simd to detect whether the CPU supports
+FP/SIMD or not. But currently, these two MACROs only consider value 0
+of ID_AA64PFR0_EL1.FP/SIMD as FP/SIMD features enabled. But for CPUs
+that support FP/SIMD and half-precision floating-point arithmetic, the
+ID_AA64PFR0_EL1.FP/SIMD are 1 (see Arm ARM DDI0487F.b, D13.2.64).
+For these CPUs, xen will treat them as no FP/SIMD support, the
+vfp_save/restore_state will not take effect.
+
+From the TRM documents of Cortex-A75/A76/N1, we know these CPUs support
+basic Advanced SIMD/FP and half-precision floating-point arithmetic. In
+this case, on N1/A76/A75 platforms, Xen will always miss the floating
+pointer registers save/restore. If different vCPUs are running on the
+same pCPU, the floating pointer registers will be corrupted randomly.
+
+This patch fixes Xen on these new cores.

+Subject: [PATCH] xen/arm: Throw messages for unknown FP/SIMD implement ID
+
+Arm ID_AA64PFR0_EL1 register provides two fields to describe CPU
+FP/SIMD implementations. Currently, we exactly know the meaning of
+0x0, 0x1 and 0xf of these fields. Xen treats value < 8 as FP/SIMD
+features presented. If there is a value 0x2 bumped in the future,
+Xen behaviors for value <= 0x1 can also take effect. But what Xen
+done for value <= 0x1 may not always cover new value 0x2 required.
+We throw these messages to break the silence when Xen detected
+unknown FP/SIMD IDs to notice user to check.
