X-Git-Tag: omap-for-v3.17/fixes-against-rc2~142^2~15^2~15 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d9cf147dbd9cef05fa08bcc1dda9b2d14d9fe567;p=pandora-kernel.git ACPICA: Application: Enhance ACPI_USAGE_xxx/ACPI_OPTION with acpi_os_printf() to improve portability This patch enhances ACPI_USAGE_xxx/ACPI_OPTION macros to use portable acpi_os_printf() so that usage functions for applications no longer rely on the printf() API. To use acpi_os_printf() exported by osunixxf.c as a replacement of printf(), applications need to initialize acpi_gbl_output_file to stdout and initialize acpi_gbl_db_output_flags to ACPI_DB_CONSOLE_OUTPUT. The latter is automatically done by ACPI_INIT_GLOBAL(), applications need to link utglobal.o to utilize this mechanism. 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 has been 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() to keep behavior consistency. acpidump has already invoked acpi_os_initialize() in this way.
