 Introduction
 ------------
-This repository contains the Arm layers for OpenEmbedded.
+This repository contains Arm layers for OpenEmbedded

-* meta-arm
+meta-arm:
+	This layer provides support for general recipes for the Arm
+	architecture.  Anything that's not needed explicitly for BSPs, the IOTA
+	distribution, or destined to be upstreamed belongs here.

-  This layer contains general recipes for the Arm architecture, such as firmware, FVPs, and Arm-specific integration.
+meta-arm-bsp:
+	This layer provides support for Arm reference platforms

-* meta-arm-autonomy
+meta-arm-iota:
+	This layer provides support for Arm's IOTA Linux Distribution

-  This layer is the distribution for a reference stack for autonomous systems.
+meta-arm-toolchain:
+	This layer provides support for Arm's GNU-A toolset releases

-* meta-arm-bsp
-
-  This layer contains machines for Arm reference platforms, for example FVP Base, N1SDP, and Juno.
-
-* meta-arm-toolchain
-
-  This layer contains recipes for Arm's binary toolchains (GCC and Clang for -A and -M), and a recipe to build Arm's GCC.
-
-* meta-atp
-
-  This layer contains recipes for the Adaptive Traffic Generation integration into meta-gem5.
-
-* meta-gem5
-
-  This layer contains recipes and machines for gem5, a system-level and processor simulator.
-
-
-Other Directories
-----------------
-
-* ci
-
-  This directory contains gitlab continuous integration configuration files (KAS yaml files) as well as scripts needed for this
-
-* kas
-
-  This directory contains KAS yaml files to describe builds for systems not used in CI
-
-* scripts
-
-  This directory contains scripts used in running the CI tests
+meta-arm-autonomy:
+    This layer provides a reference stack for autonomous systems.

-# Set SRC_URI from Variable
-
-# This class parses a variable named in SRC_URI_FROM_VAR_NAME for entries that
-# should be added to the SRC_URI
-#
-# There are 4 supported formats for entries:
-#
-# - http/https url
-#   - Note that a checksum (md5sum or sha256sum) must be provided for http(s)
-#
-# - file:// absolute local path from root
-#   - In this case the filename will be added to SRC_URI and the path from '/'
-#   added to FILESEXTRAPATHS
-#
-# - file:// path relative to FILESEXTRAPATHS
-#   - In this case the filename will be added to SRC_URI and the preceding path
-#   added to FILESOVERRIDES, so that the full path to the file will
-#   be available in FILESPATH when it is generated by combining
-#   FILESEXTRAPATHS and FILESOVERRIDES.
-#
-# - plain absolute local path from root
-#   - This will be treated the same as an file:// path from root. Plain paths
-#   must be absolute, and cannot be relative to FILESEXTRAPATHS
-#
-# It is not recommended to use other yocto URL types, as they may result in
-# undefined behaviour.
-#
-# These entries will be added to the SRC_URI so that the yocto fetcher can
-# unpack a copy into ${WORKDIR}/${SRC_URI_FROM_VAR_UNPACK_DIR}
-#
-#
-# A list of arguments can follow each entry in the input variable, seperated
-# by semi-colons (;). Arguments may be FETCH arguments or MANIFEST arguments.
-#
-# FETCH arguments will be appended to the entry in SRC_URI, for example
-# "downloadfilename" to specify the filename used when storing a
-# downloaded file.
-# Each SRC_URI entry will automatically have the arguments
-# "unpack=0;subdir=${SRC_URI_FROM_VAR_UNPACK_DIR}" added to them, so do not
-# attempt to set these options.
-#
-# MANIFEST arguments are defined in the variable
-# SRC_URI_FROM_VAR_MANIFEST_PARAMS which should be a space seperated list of
-# names, each optionally followed by an equals sign (=) and a default value.
-#
-# The values provided for the manifest arguments will be written to the manifest
-# file in ${WORKDIR}/${SRC_URI_FROM_VAR_UNPACK_DIR} as columns, in the same
-# order as they appear in SRC_URI_FROM_VAR_MANIFEST_PARAMS.
-#
-# For entries that do not provide a value for a manifest argument, the default
-# value will be used if possible.
-# If no default is availale, omitting the parameter on any item will cause
-# an error.
-#
-# "[basename]" is a special case default that will set the value to
-# the filename without the path or file extension.
-#
-# e.g.
-# SRC_URI_FROM_VAR_MANIFEST_PARAMS="conname=[basename] contag=local conkeep"
-#
-# Any arguments that follow an entry in SRC_URI_FROM_VAR_NAME, that are not
-# named in SRC_URI_FROM_VAR_MANIFEST_PARAMS are assumed to be FETCH arguments,
-# so are added to the corresponding entry in the SRC_URI.

+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.
