+# meta-xilinx-vendor
+This layer enables AMD Xilinx Xen configurations and features for ZynqMP and
+Versal devices and also provides related metadata.
+## Xen Build Instructions
+The Yocto Project setup for AMD Xilinx Xen configurations workflow is as follows.
+Be sure to read everything below.
+1. Follow [Building Instructions](../README.building.md) upto step 2.
+2. Clone the meta-security repository.
+```
+$ git clone -b <release-branch> https://git.yoctoproject.org/meta-security
+```
+3. Continue [Building Instructions](../README.building.md) from step 4.
+> **Note:**
+> * For System Device Tree(SDT) workflow see [SDT Building Instructions](../meta-xilinx-standalone-experimental/README.md)
+4. Add meta-xilinx-virtualization layer to bblayers.conf as shown below.
+```
+$ bitbake-layers add-layer ./<path-to-layer>/meta-xilinx/meta-xilinx-virtualization
+```
+5. The following variables needs to be added to the end of the conf/local.conf file.
+```
+# Xen variables
+BOOTMODE = "xen"
+ENABLE_XEN_UBOOT_SCR = "1"
+ENABLE_XEN_DTSI = "1"
+ENABLE_XEN_QEMU_DTSI = "1"
+DISTRO_FEATURES:append = " multiarch security tpm virtualization vmsep xen"
+IMAGE_FEATURES += "ssh-server-openssh"
+DISTRO_FEATURES:append = " systemd"
+VIRTUAL-RUNTIME_init_manager = "systemd"
+DISTRO_FEATURES_BACKFILL_CONSIDERED = "sysvinit"
+IMAGE_INSTALL:append = " \
+    kernel-module-xen-blkback \
+    kernel-module-xen-gntalloc \
+    kernel-module-xen-gntdev \
+    kernel-module-xen-netback \
+    kernel-module-xen-wdt \
+    xen \
+    xen-tools \
+    xen-tools-xenstat \
+    ${@bb.utils.contains('DISTRO_FEATURES', 'vmsep', 'qemu-aarch64 qemu-keymaps', 'qemu', d)} \
+    "
+```
+6. Continue [Building Instructions](../README.building.md) from step 5.
+## Xen Boot Instructions
+> **Note:**
+> * This README provides instructions for Xen Dom0 only.
+1. Follow [Booting Instructions](../README.booting.md) upto step 2.
+2. Verify Xen Dom0 is up and running on QEMU or target as shown below.

+Subject: [PATCH 2/8] xen: add pseudo RAM region for grant mappings
+Add a memory region which can be used to automatically map granted
+memory. It is starting at 0x8000000000000000ULL in order to be able to
+distinguish it from normal RAM.
+For this reason the xen.ram memory region is expanded, which has no
+further impact as it is used just as a container of the real RAM
+regions and now the grant region.

+Today xen_ram_addr_from_mapcache() will either abort() or return 0 in

+are bad, so change that to return an invalid address instead.

+Subject: [PATCH 5/8] memory: add MemoryRegion map and unmap callbacks
+In order to support mapping and unmapping guest memory dynamically to
+and from qemu during address_space_[un]map() operations add the map()
+and unmap() callbacks to MemoryRegionOps.
+Those will be used e.g. for Xen grant mappings when performing guest
+I/Os.

+From 87d362e72e65b604da7554657204344a6540d88c Mon Sep 17 00:00:00 2001
+From: Vikram Garhwal <vikram.garhwal@amd.com>
+Date: Fri, 1 Jul 2022 15:59:47 -0700
+Subject: [PATCH 06/16] xen-hvm: move common functions to
+ hw/xen/xen-hvm-common.c
+Extract common functionalities from xen-hvm.c and move them to
+hw/xen/xen-hvm-common.c. These common functions are useful for creating
+an IOREQ server.
+Moved the common usable IOREQ creation part to a new function
+xen_register_ioreq() which can be used by both x86 and ARM machines.
+NOTE: This patch will break the build as the patch only involves moving
+of functions. Build fixes will be in the next patch.

+Subject: [PATCH 07/16] xen: skip ioreq creation on ioreq registration failure
+On ARM it is possible to have a functioning xenpv machine with only the
+PV backends and no IOREQ server. If the IOREQ server creation fails
+continue to the PV backends initialization.

+Subject: [PATCH 10/16] hw/arm: introduce xenpv machine
+Create a new machine xenpv which creates a IOREQ server to connect
+with Xen. It also creates a tpm-tis-device which connects to swtpm to
+support TPM functionalities.
+Xen IOREQ connection expect the TARGET_PAGE_SIZE to 4096, and the xenpv
+machine on ARM will have no CPU definitions. We need to define
+TARGET_PAGE_SIZE appropriately ourselves.

+Subject: [PATCH 14/16] xen_arm: Create virtio-mmio devices during
+ initialization
+In order to use virtio backends we need to allocate virtio-mmio
+parameters (irq and base) and register corresponding buses.
+Use the constants defined in public header arch-arm.h to be
+aligned with the toolstack. So the number of current supported
+virtio-mmio devices is 10.
+For the interrupts triggering use already existing on Arm
+device-model hypercall.
+The toolstack should then insert the same amount of device nodes
+into guest device-tree.

+Subject: [PATCH 16/16] xen_arm: Add "accel = xen" and drop extra interface
+ openings
+In order to use virtio backends we need to make sure that Xen accelerator
+is enabled (xen_enabled() returns true) as the memory/cache systems
+check for xen_enabled() to perform specific actions. Without that
+the xen-mapcache (which is needed for mapping guest memory) is not in use.
+Also drop extra interface opening as this is already done in xen-all.c
+(so drop xen_init_ioreq() completely) and skip virtio/tpm initialization
+if device emulation is not available.

+Subject: [PATCH] arm: xenpvh: Introduce virtio-pci support
+The bridge is needed for virtio-pci support, as QEMU can emulate the
+whole bridge with any virtio-pci devices connected to it.
+NOTE: A few xen-hvm-common.c and xen_native.h changes are cherry-picked from
+EPAM QEMU patches for xen-arm. This was done to keep least diff with upstream.

+Subject: [PATCH 01/11] xen_arm: Create virtio-mmio devices during
+ initialization
+In order to use virtio backends we need to allocate virtio-mmio
+parameters (irq and base) and register corresponding buses.
+Use the constants defined in public header arch-arm.h to be
+aligned with the toolstack. So the number of current supported
+virtio-mmio devices is 10.
+For the interrupts triggering use already existing on Arm
+device-model hypercall.
+The toolstack should then insert the same amount of device nodes
+into guest device-tree.

+Subject: [PATCH 02/11] xen_arm: Initialize RAM and add hi/low memory regions
+In order to use virtio backends we need to initialize RAM for the
+xen-mapcache (which is responsible for mapping guest memory using foreign
+mapping) to work. Calculate and add hi/low memory regions based on
+machine->ram_size.
+Use the constants defined in public header arch-arm.h to be aligned with the xen
+toolstack.
+While using this machine, the toolstack should then pass real ram_size using
+"-m" arg. If "-m" is not given, create a QEMU machine without IOREQ and other
+emulated devices like TPM and VIRTIO. This is done to keep this QEMU machine
+usable for /etc/init.d/xencommons.

+Subject: [PATCH 06/11] xen: add pseudo RAM region for grant mappings
+Add a memory region which can be used to automatically map granted
+memory. It is starting at 0x8000000000000000ULL in order to be able to
+distinguish it from normal RAM.
+For this reason the xen.ram memory region is expanded, which has no
+further impact as it is used just as a container of the real RAM
+regions and now the grant region.

+Upstream-Status: Xen: Inappropriate [oe specific, cross compile issue]

+commit e6972e689a980ab28637e94e48c77eeace6abde5
+    xen/kconfig,menuconfig,mconf-cfg: Allow specification of ncurses location
+    In some cross build environments such as the Yocto Project build
+    environment it provides an ncurses library that is compiled
+    differently than the host's version.  This causes display corruption
+    problems when the host's curses includes are used instead of the
+    includes from the provided compiler are overridden.  There is a second
+    case where there is no curses libraries at all on the host system and
+    menuconfig will just fail entirely.
+    The solution is simply to allow an override variable in
+    check-lxdialog.sh for environments such as the Yocto Project.  Adding
+    a CROSS_CURSES_LIB and CROSS_CURSES_INC solves the issue and allowing
+    compiling and linking against the right headers and libraries.

+Allow to respect the target install dir (PYTHON_SITEPACKAGES_DIR)

+Unfortunatly, adding prerequisite to "$(obj)/ss/built_in.o" doesn't
+work because we have "$(obj)/%/built_in.o: $(obj)/% ;" in Rules.mk.
+So, make is allow to try to build objects in "xsm/flask/ss/" before
+generating the headers.
+Adding a prerequisite on "$(obj)/ss" instead will fix the issue has
+that the target used to run make in this subdirectory.
+Unfortunatly, that target is also used when running `make clean`, so
+we need to ignore it in this case. $(MAKECMDGOALS) can't be used in
+this case as it is empty, but we can guess which operation is done by
+looking at the list of loaded makefiles.
