From 75c349062a666deab57bdca8b5bd0779c9fb0d58 Mon Sep 17 00:00:00 2001 From: Vincent Sanders Date: Thu, 18 Sep 2014 20:39:15 +0100 Subject: ARM: 8153/1: Enable gcov support on the ARM architecture Enable gcov support for ARM based on original patches by David Singleton and George G. Davis Riku - updated to patch to current mainline kernel. The patch has been submitted in 2010, 2012 - for symmetry, now in 2014 too. https://lwn.net/Articles/390419/ http://marc.info/?l=linux-arm-kernel&m=133823081813044 v2: remove arch/arm/kernel from gcov disabled files Cc: Andrey Ryabinin Cc: Naresh Kamboju Acked-by: Arnd Bergmann Signed-off-by: Riku Voipio Signed-off-by: Vincent Sanders Signed-off-by: Russell King diff --git a/arch/arm/boot/bootp/Makefile b/arch/arm/boot/bootp/Makefile index c394e30..5761f00 100644 --- a/arch/arm/boot/bootp/Makefile +++ b/arch/arm/boot/bootp/Makefile @@ -5,6 +5,8 @@ # architecture-specific flags and dependencies. # +GCOV_PROFILE := n + LDFLAGS_bootp :=-p --no-undefined -X \ --defsym initrd_phys=$(INITRD_PHYS) \ --defsym params_phys=$(PARAMS_PHYS) -T diff --git a/arch/arm/boot/compressed/Makefile b/arch/arm/boot/compressed/Makefile index 76a50ec..3ea230a 100644 --- a/arch/arm/boot/compressed/Makefile +++ b/arch/arm/boot/compressed/Makefile @@ -37,6 +37,8 @@ ifeq ($(CONFIG_ARM_VIRT_EXT),y) OBJS += hyp-stub.o endif +GCOV_PROFILE := n + # # Architecture dependencies # diff --git a/kernel/gcov/Kconfig b/kernel/gcov/Kconfig index d04ce8a..cf66c5c 100644 --- a/kernel/gcov/Kconfig +++ b/kernel/gcov/Kconfig @@ -35,7 +35,7 @@ config GCOV_KERNEL config GCOV_PROFILE_ALL bool "Profile entire Kernel" depends on GCOV_KERNEL - depends on SUPERH || S390 || X86 || PPC || MICROBLAZE + depends on SUPERH || S390 || X86 || PPC || MICROBLAZE || ARM default n ---help--- This options activates profiling for the entire kernel. -- cgit v0.10.2
