In order to enable changing the generated C configuration files manually,
this patch introduces the target `diffconfig` to the build system.
After generating the configuration files, a developer can manually modify
these sources (which are placed under build/configs) and invoke `make
diffconfig` to generate a patch that shows the made differences. Such
patches can be registered to a build by invoking the `applydiffconfig`
target. The build system will always apply them whenever the configuration
files are regenerated.
A typical workflow to create a patch is as follows.
# The pre_build target relies on generated configuration files
hypervisor$ make BOARD=xxx SCENARIO=yyy pre_build
(manually edit files under build/configs/boards and
build/configs/scenarios)
hypervisor$ make diffconfig # Patch generated to build/config.patch
hypervisor$ cp build/config.patch /path/to/patch
The following steps apply apply the patch to another build.
hypervisor$ make BOARD=xxx SCENARIO=yyy defconfig
hypervisor$ make applydiffconfig PATCH=/path/to/patch-file-or-directory
hypervisor$ make
After any patch is registered for a build, the configuration files will be
automatically regenerated the next time `make` is invoked.
To show a list of registered patches for generated configuration files,
invoke `make applydiffconfig` without specifying `PATCH`.
v2:
* Add target `applydiffconfig` which accepts a PATCH variable to register
an arbitrary patch file or a directory containing patch file(s) for a
build. `.config_patches` is no longer used.

This patch makes the build system of the hypervisor to cache the board and
scenario XML files in the build directory and generate C configuration
files from them at build time. The C configuration files that are cached in
the git repo is no longer used or updated. Paths to these generated files
in the prebuild Makefile is updated accordingly.
The following targets are introduced or modified.
* defconfig: Copy default configuration XMLs to the build directory and
generate C configuration files.
* oldconfig: No action.
* menuconfig: Print a message to redirect users to use the config app
and exit.
* showconfig: Print the BOARD, SCENARIO and RELEASE configured for the
current build.
* update_config: No action.
* (default): Build the hypervisor with defined configurations.
The following variables can be set on the command line to specify the
default configuration to be used.
* BOARD: Either a name of the target board or a path to a customized
board XML. When a board name is specified, the board XML file
is expected to be available under
misc/acrn-config/xmls/board-xmls.
* SCENARIO: Either a name of the scenario of a path to a customized
scenario XML. When a scenario name is specified, the
scenario XML file is expected to be available under
misc/acrn-config/xmls/config-xmls/$(BOARD).
* BOARD_FILE: Path to the board XML file to be used. This is now
obsoleted as BOARD provides the same functionality.
* SCENARIO_FILE: Path to the scenario XML file to be used. This is now
obsoleted as BOARD provides the same functionality.
BOARD/SCENARIO or BOARD_FILE/SCENARIO_FILE shall be used in pair, and
BOARD_FILE/SCENARIO_FILE shall point to valid files when specified. Any
violation to those constraints will stop the build with error
messages. When BOARD/SCENARIO and BOARD_FILE/SCENARIO_FILE are both defined
on the command line, the former takes precedence as the latter are to be
obsoleted.
Additionally, users can define the RELEASE variable to specify a debug or
release build. In case a previous build exists but is configured for a
different build type, the build system will automatically update the
scenario XML and rebuild the sources.
This patch also includes the following tweaks:
1. Do not use `realpath` to process search paths for generated
headers. `realpath` only accepts paths of existing files, while the
directories for generated headers may not be created at the time the
search paths are calculated.
2. Always expect `pci_dev.c` to be in place.
3. HV_CONFIG_* series now encodes absolute paths.
v3:
* Do not validate BOARD_FILE/SCENARIO_FILE if BOARD/SCENARIO are given.
v2:
* `defconfig` now also generates the C configuration files.
* BOARD/SCENARIO now accept either board/scenario names or XML file paths.
* Adapt to the new allocation.xml & unified.xml.
* Cleanup names of internal variables in config.mk for brevity.

In order to remove Kconfig from the build process, acrn-config shall
transform XML configuration files to config.h and config.mk by itself. This
patch adds XSLT scripts that do the trick.
Unfortunately, the scenario XML file along is not sufficient to generate
config.h and config.mk, though. In addition to resource
allocation (i.e. allocating physical RAM for the hypervisor), the
transformation also need to do the following:
1. Translate UART info in board XML into several configuration entries
depending on the UART selected in the scenario XML.
2. Use the MAX_MSIX_TABLE_NUM value in the board XML if the scenario
XML does not specify it.
In order to use XSLT to transform both XMLs in one shot, a template is
provided to create another XML that includes (using XInclude) both board
and scenario XMLs as sub-nodes. It will be instantiated once the
transformations are integrated in the following patch.
v2:
* Add `allocation.xml` to `unified.xml` to include the results from static
allocation.
* Use HV_RAM_START and HV_RAM_SIZE in allocation results if they are not
explicitly specified in the scenario XML.

In order to split the allocation logic from tranformation in the
configuration tool, this patch introduces the `static_allocators` directory
under `misc/acrn-config` to host scripts that statically allocate
resources (currently the physical memory) and fill the scenario XML with
the results. The logic is extracted from the existing configuration tool
which allocates resources when transforming XML files, while XPath is used
to read and manipulate the XML when possible.
The aim is to make transformation from XML files to C configuration sources
to be more trivial and easier to express in descriptive languages like
XSLT.
v2:
* Instead of rewriting the scenario XML, the new version generates
allocation results to a new XML named `allocation.xml` so that the form
of the results are not restricted by the XML schema.

In order for a unified interface for generating configuration sources from
board and scenario XMLs, this patch introduces a script named genconf.sh
which takes XML files as inputs and generate sources under the specified
directory. Once used in Makefiles, this script helps to minimize the
impacts on the Makefiles when we refine the configuration source generation
process in the future.
This patch also adds a non-zero return value to board_cfg_gen.py and
scenario_cfg_gen.py so that we do not need to inspect the logs to determine
if the generation succeeds.
