From 798d91039849486c7a4f1a458a5680cb55a65408 Mon Sep 17 00:00:00 2001 From: Thomas Renninger Date: Thu, 31 May 2007 17:20:39 +0200 Subject: ACPI: create CONFIG_ACPI_DEBUG_FUNC_TRACE Split ACPI_DEBUG into function trace enabled and not enabled. Function trace is most of the ACPI_DEBUG costs, but is not much of use for kernel ACPI debugging. Size of kernel image increased on test compile: + 48k (Full ACPI_DEBUG) + 35k (ACPI_DEBUG with function trace compiled out) Performance without function trace is also much better. Also remove ACPI_LV_DEBUG_OBJECT from default debug level as a lot vendors let Store (value, debug) in their code and this might confuse users when it pops up in syslog.
