From 83b80bace4bdfc61abd16ca6ad0a51734a0f57f0 Mon Sep 17 00:00:00 2001 From: Lv Zheng Date: Tue, 8 Jul 2014 10:06:45 +0800 Subject: [PATCH] ACPICA: OSL: Clean up acpi_os_printf()/acpi_os_vprintf() stubs 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.
