[resending, cutting out git pull-request output to make message smaller]
Hi all,
I have written a COM32 module called "acpioff", that, not surprisingly,
powers off a machine using ACPI. I have tested it only using pxelinux.0
with a SeaBIOS/Qemu virtual machine.
Since the changeset pulls in a "Linux-ized" version of the open source
ACPI Component Architecture, it was too big to post as a patches to the
list. See the git pull-request output below. My github tree is from a
clone of the git.kernel.org syslinux git tree.
I have two questions which I would like answered, since I don't like to
maintain things out of tree:
a) Is there any possibilty that this could be included in the official
syslinux source tree?
b) If so, what changes do I need to make to the patch for it to be
accepted?
Note that this COM32 module implements a single-threaded instantiation
of the ACPICA for itself that ignores the SCI interrupt. The acpioff.c
program using the syslinux COM32 library act as the "OS" for the ACPICA
instantiation.
The changeset is very large due to the ACPICA, but the following files
are what really matter for review purposes:
Program:
com32/acpioff/acpioff.c
com32/Makefile
Platform/enviroment specific customization required for
single-threaded ACPI instantiation for COM32:
com32/acpioff/acpica_linuxized/README
com32/acpioff/osl.h
com32/acpioff/acpica_linuxized/drivers/acpi/osl.c
com32/acpioff/acpica_linuxized/include/acpi/platform/accom32.h
com32/acpioff/acpica_linuxized/include/acpi/platform/acenv.h
Fixes required to the ACPICA for available types and debugging:
com32/acpioff/acpica_linuxized/drivers/acpi/acpica/acglobal.h
com32/acpioff/acpica_linuxized/drivers/acpi/acpica/utaddress.c
com32/acpioff/acpica_linuxized/drivers/acpi/acpica/acutils.h
Regards,
Andy
