Date: Mon, 28 Oct 2013 11:53:53 -0700 From: "Luck, Tony" <tony.luck@...el.com> To: Matt Fleming <matt@...sole-pimps.org> Cc: Ingo Molnar <mingo@...nel.org>, Tony Luck <tony.luck@...il.com>, Linux Kernel Mailing List <linux-kernel@...r.kernel.org>, Borislav Petkov <bp@...en8.de>, Christoph Hellwig <hch@...radead.org>, Chen Gong <gong.chen@...ux.intel.com>, X86-ML <x86@...nel.org> Subject: [PATCH] Move cper.c from drivers/acpi/apei to drivers/firmware/efi cper.c contains code to decode and print "Common Platform Error Records". Originally added under drivers/acpi/apei because the only user was in that same directory - but now we have another consumer, and we shouldn't have to force CONFIG_ACPI_APEI get access to this code. Since CPER is defined in the UEFI specification - the logical home for this code is under drivers/firmware/efi/ Signed-off-by: Tony Luck <tony.luck@...el.com> --- Matt: as discussed earlier on the mailing list ... just looking for your "Acked-by" so this can go on top of the patch series in the x86/mce branch of the tip tree that already makes a bunch of changes to cper.c Based on Chen Gong's original patch that moved cper.c to lib/ diff --git a/drivers/acpi/Kconfig b/drivers/acpi/Kconfig index 252f0e818a49..08eadb4a57cb 100644 --- a/drivers/acpi/Kconfig +++ b/drivers/acpi/Kconfig @@ -374,7 +374,9 @@ source "drivers/acpi/apei/Kconfig" config ACPI_EXTLOG tristate "Extended Error Log support" - depends on X86_MCE && ACPI_APEI + depends on X86_MCE + select EFI + select UEFI_CPER default n help Certain usages such as Predictive Failure Analysis (PFA) require diff --git a/drivers/acpi/apei/Kconfig b/drivers/acpi/apei/Kconfig index f0c1ce95a0ec..786294bb682c 100644 --- a/drivers/acpi/apei/Kconfig +++ b/drivers/acpi/apei/Kconfig @@ -2,6 +2,8 @@ config ACPI_APEI bool "ACPI Platform Error Interface (APEI)" select MISC_FILESYSTEMS select PSTORE + select EFI + select UEFI_CPER depends on X86 help APEI allows to report errors (for example from the chipset) diff --git a/drivers/acpi/apei/Makefile b/drivers/acpi/apei/Makefile index d1d1bc0a4ee1..5d575a955940 100644 --- a/drivers/acpi/apei/Makefile +++ b/drivers/acpi/apei/Makefile @@ -3,4 +3,4 @@ obj-$(CONFIG_ACPI_APEI_GHES) += ghes.o obj-$(CONFIG_ACPI_APEI_EINJ) += einj.o obj-$(CONFIG_ACPI_APEI_ERST_DEBUG) += erst-dbg.o -apei-y := apei-base.o hest.o cper.o erst.o +apei-y := apei-base.o hest.o erst.o diff --git a/drivers/firmware/efi/Kconfig b/drivers/firmware/efi/Kconfig index b0fc7c79dfbb..8dfdd2a1cf12 100644 --- a/drivers/firmware/efi/Kconfig +++ b/drivers/firmware/efi/Kconfig @@ -36,4 +36,7 @@ config EFI_VARS_PSTORE_DEFAULT_DISABLE backend for pstore by default.
