2013-10-31Move cper.c from drivers/acpi/apei to drivers/firmware/efiLuck, Tony
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/ Acked-by: Matt Fleming <matt.fleming@intel.com> Acked-by: Ingo Molnar <mingo@kernel.org> Signed-off-by: Tony Luck <tony.luck@intel.com>
2013-04-17efi: split efisubsystem from efivarsTom Gundersen
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 <seiji.aguchi@hds.com> Cc: Tony Luck <tony.luck@intel.com> Cc: Mike Waychison <mikew@google.com> Cc: Kay Sievers <kay@vrfy.org> Cc: Jeremy Kerr <jk@ozlabs.org> Cc: Matthew Garrett <mjg59@srcf.ucam.org> Cc: Chun-Yi Lee <jlee@suse.com> Cc: Andy Whitcroft <apw@canonical.com> Cc: Tobias Powalowski <tpowa@archlinux.org> Signed-off-by: Tom Gundersen <teg@jklm.no> Signed-off-by: Matt Fleming <matt.fleming@intel.com>
2013-04-17efivars: Move pstore code into the new EFI directoryMatt Fleming
efivars.c has grown far too large and needs to be divided up. Create a new directory and move the persistence storage code to efi-pstore.c now that it uses the new efivar API. This helps us to greatly reduce the size of efivars.c and paves the way for moving other code out of efivars.c. Note that because CONFIG_EFI_VARS can be built as a module efi-pstore must also include support for building as a module.
