platform/x86/intel/ifs: Remove unused selectionCONFIG_INTEL_IFS_DEVICE is not used anywhere. The selection inKconfig is therefore pointless.

platform/x86/intel/ifs: Mark as BROKENA recent suggested change to the IFS code has shown that the userspaceAPI needs a bit more work, see:https://lore.kernel.org/platform-driver-x86/20220708151938.986530-1-jithu.joseph@intel.com/Mark it as BROKEN before 5.19 ships, to give ourselves one morekernel-devel cycle to get the userspace API right.Link: https://lore.kernel.org/platform-driver-x86/20220708151938.986530-1-jithu.joseph@intel.com/Cc: Jithu Joseph Cc: Ashok Raj Cc: Tony Luck Suggested-by: Greg KH Signed-off-by: Hans de Goede Acked-by: Greg Kroah-Hartman Link: https://lore.kernel.org/r/20220710140736.6492-1-hdegoede@redhat.com List of files: /linux-6.15/drivers/platform/x86/intel/ifs/Kconfig

67896ef1 - platform/x86/intel/ifs: Add stub driver for In-Field Scan

Fri, 06 May 2022 22:54:02 +0000

platform/x86/intel/ifs: Add stub driver for In-Field ScanCloud Service Providers that operate fleets of servers have reported[1] occasions where they can detect that a CPU has gone bad due toeffects like electromigration, or isolated manufacturing defects.However, that detection method is A/B testing seemingly randomapplication failures looking for a pattern. In-Field Scan (IFS) isa driver for a platform capability to load a crafted 'scan image'to run targeted low level diagnostics outside of the CPU's architecturalerror detection capabilities.Stub version of driver just does initial part of check for the IFSfeature.
