[Xen-devel] [PATCH v1 00/20] Make ACPI builder available to components other than hvmloader

[Boris Ostrovsky <boris.ostrovsky@xxxxxxxxxx>]

This is V1 of the series posted earlier as an RFC

The goal here is to build ACPI tables for PVHv2/HVMlite guests while reusing 
existing
hvmloader's ACPI builder code. The builder is provided as a library in 
tools/libacpi.

Main changes from RFC are:
* Move toolstack code that loads the tables into PVHv2 guest from libxc to libxl
* Don't provide the builder to hypervisor as we didn't find a user for that (at 
least so far)
* Update e820 map for PVHv2 guests when ACPI tables are loaded
* Don't set HW_REDUCED_ACPI flags: this flag is only available starting with 
ACPI v5
* Separate ACPI-specific definition from libacpi definitions (i.e. acpi2_0.h vs 
libacpi.h)
* Add Processor objects to PVHv2's AML
* Separate out ACPI INFO description into a separate ASL file
* Specify ACPI INFO and tables' addresses in callers' code (not in acpi2_0.h)
* Build ASL/C files in targets' directories (Jan suggested making symlinks, 
this is slightly
  different but serves similar goal of preventing paralell make from making a 
mess of targets)
* Rework include files (x86.h), make callers specify include file that defines 
standard tools
  (see for example patch 13)
* Reorder some patches to decrease code churn

Other changes are described in patches (given number of changes I may have 
missed
mentioning some).

Boris Ostrovsky (20):
  hvmloader: Provide hvmloader_acpi_build_tables()
