ACPICA: OSL: Clean up acpi_os_printf()/acpi_os_vprintf() stubs

2014-07-08T12:22:25+00:00

This patch is mainly for acpidump where there are redundant
acpi_os_printf()/acpi_os_vprintf() stubs implemented. This patch cleans up such
specific implementation by linking acpidump to osunixxf.c/oswinxf.c.

To make acpi_os_printf() exported by osunixxf.c/oswinxf.c to behave as the
old acpidump specific ones, applications need to:
 1. Initialize acpi_gbl_db_output_flags to ACPI_DB_CONSOLE_OUTPUT.
    This is automatically done by ACPI_INIT_GLOBAL(), applications need to
    link utglobal.o to utilize this mechanism.
 2. Initialize acpi_gbl_output_file to stdout.
    For GCC, assigning stdout to acpi_gbl_output_file using ACPI_INIT_GLOBAL()
    is not possible as stdout is not a constant in GCC environment. As an
    alternative solution, stdout assignment is put into acpi_os_initialize().
    Thus acpi_os_initialize() need to be invoked very early by the
    applications to initialize the default output of acpi_os_printf().

This patch also releases osunixxf.c to the Linux kernel. Lv Zheng.

ACPICA: Utilities: Cleanup DEFINE_ACPI_GLOBALS by moving acpi_ut_init_global() from utglobal.c to utinit.c

2014-07-08T12:22:25+00:00

The utglobal.c is used to define and initialize global variables.  It makes
sense if just adding utglobal.o to applications that are using such
variables. But acpi_ut_init_globals() is preventing us from doing so as
this initialization function references other components' initializations
code, which leads to the requirement that many files should also get linked
if one wants to link utglobal.o.

It is possible to just move acpi_ut_init_global() to utinit.c for
applications that require this function to link.

By linking utglobal.o, we can stop defining DEFINE_ACPI_GLOBALS for
applications (currently only acpidump is affected). Lv Zheng.

ACPICA/ACPI: Add new host interfaces for _OSI support

2010-10-01T05:47:43+00:00

Adds install/remove interfaces so that the host can dynamically
alter the global _OSI table. Also adds support for _OSI handlers.
Additional support: new debugger command (osi), and test support in
the acpiexec utility. Adds new file, utilities/utosi.c.
ACPICA bugzilla 836.

The Linux OSL _OSI code is also changed.
acpi_osi_setup can't call acpi_install/remove_interface because ACPICA
is not initialized yet at this early time.
So we just save the osi string in acpi_osi_setup and will handle it
later in a new function acpi_osi_setup_late.
