From a9499fa7cd3fd4824a7202d00c766b269fa3bda6 Mon Sep 17 00:00:00 2001 From: Tom Gundersen Date: Fri, 8 Feb 2013 15:37:06 +0000 Subject: efi: split efisubsystem from efivars This registers /sys/firmware/efi/{,systab,efivars/} whenever EFI is enabled and the system is booted with EFI. This allows *) userspace to check for the existence of /sys/firmware/efi as a way to determine whether or it is running on an EFI system. *) 'mount -t efivarfs none /sys/firmware/efi/efivars' without manually loading any modules. [ Also, move the efivar API into vars.c and unconditionally compile it. This allows us to move efivars.c, which now only contains the sysfs variable code, into the firmware/efi directory. Note that the efivars.c filename is kept to maintain backwards compatability with the old efivars.ko module. With this patch it is now possible for efivarfs to be built without CONFIG_EFI_VARS - Matt ] Cc: Seiji Aguchi Cc: Tony Luck Cc: Mike Waychison Cc: Kay Sievers Cc: Jeremy Kerr Cc: Matthew Garrett Cc: Chun-Yi Lee Cc: Andy Whitcroft Cc: Tobias Powalowski Signed-off-by: Tom Gundersen Signed-off-by: Matt Fleming --- drivers/firmware/Makefile | 1 - 1 file changed, 1 deletion(-) (limited to 'drivers/firmware/Makefile') diff --git a/drivers/firmware/Makefile b/drivers/firmware/Makefile index 31bf68c93593..299fad6b5867 100644 --- a/drivers/firmware/Makefile +++ b/drivers/firmware/Makefile @@ -4,7 +4,6 @@ obj-$(CONFIG_DMI) += dmi_scan.o obj-$(CONFIG_DMI_SYSFS) += dmi-sysfs.o obj-$(CONFIG_EDD) += edd.o -obj-$(CONFIG_EFI_VARS) += efivars.o obj-$(CONFIG_EFI_PCDP) += pcdp.o obj-$(CONFIG_DELL_RBU) += dell_rbu.o obj-$(CONFIG_DCDBAS) += dcdbas.o -- cgit v1.2.3
