For FuSa's case, we remove all dynamic memory allocation use in ACRN HV. Instead,
we use static memory allocation or embedded data structure. For pagetable page,
we prefer to use an index (hva for MMU, gpa for EPT) to get a page from a special
page pool. The special page pool should be big enougn for each possible index.
This is not a big problem when we don't support 64 bits MMIO. Without 64 bits MMIO
support, we could use the index to search addrss not larger than DRAM_SIZE + 4G.
However, if ACRN plan to support 64 bits MMIO in SOS, we could not use the static
memory alocation any more. This is because there's a very huge hole between the
top DRAM address and the bottom 64 bits MMIO address. We could not reserve such
many pages for pagetable mapping as the CPU physical address bits may very large.
This patch will use dynamic page allocation for pagetable mapping. We also need
reserve a big enough page pool at first. For HV MMU, we don't use 4K granularity
page table mapping, we need reserve PML4, PDPT and PD pages according the maximum
physical address space (PPT va and pa are identical mapping); For each VM EPT,
we reserve PML4, PDPT and PD pages according to the maximum physical address space
too, (the EPT address sapce can't beyond the physical address space), and we reserve
PT pages by real use cases of DRAM, low MMIO and high MMIO.

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.

Some passthrough devices require multiple MSI vectors, but don't

vector allocation.
On native platform, this issue can be mitigated by IOMMU via interrupt
remapping. However, on ACRN, there is no vIOMMU.
vMSI-X on MSI emulation is one solution to mitigate this problem on ACRN.
This patch adds MSI-X emulation on MSI capability.
For the device needs to do MSI-X emulation, HV will hide MSI capability
and present MSI-X capability to guest.
The guest driver may need to modify to reqeust MSI-X vector.
For example:
ret = pci_alloc_irq_vectors(pdev, 1, STMMAC_MSI_VEC_MAX,
- PCI_IRQ_MSI);
+ PCI_IRQ_MSI | PCI_IRQ_MSIX);
To enable MSI-X emulation, the device should:
- 1. The device should be in vmsix_on_msi_devs array.
- 2. Support MSI, but don't support MSI-X.
- 3. MSI capability should support per-vector mask.
- 4. The device should have an unused BAR.
- 5. The device driver should not rely on PBA for functionality.
