5a0fcb0e - cxl: Remove driver

Wed, 19 Feb 2025 07:00:06 +0000

cxl: Remove driverRemove the cxl driver that provides support for the IBM CoherentAccelerator Processor Interface. Revert or clean up associated code inarch/powerpc that is no longer necessary.cxl has received minimal maintenance for several years, and is notsupported on the Power10 processor. We aren't aware of any users who arelikely to be using recent kernels.Thanks to Mikey Neuling, Ian Munsie, Daniel Axtens, Frederic Barrat,Christophe Lombard, Philippe Bergheaud, Vaibhav Jain and AlastairD'Silva for their work on this driver over the years.Signed-off-by: Andrew Donnellan Acked-by: Frederic Barrat Acked-by: Madhavan Srinivasan Signed-off-by: Michael Ellerman Link: https://patch.msgid.link/20250219070007.177725-2-ajd@linux.ibm.com List of files: /linux-6.15/drivers/misc/Makefile

185686be - misc: Add support for LAN966x PCI device

Mon, 14 Oct 2024 12:46:30 +0000

misc: Add support for LAN966x PCI deviceAdd a PCI driver that handles the LAN966x PCI device using a device-treeoverlay. This overlay is applied to the PCI device DT node and allows todescribe components that are present in the device.The memory from the device-tree is remapped to the BAR memory thanks to"ranges" properties computed at runtime by the PCI core during the PCIenumeration.The PCI device itself acts as an interrupt controller and is used as theparent of the internal LAN966x interrupt controller to route theinterrupts to the assigned PCI INTx interrupt.Signed-off-by: Herve Codina Acked-by: Greg Kroah-Hartman Acked-by: Bjorn Helgaas # quirks.cLink: https://lore.kernel.org/r/20241014124636.24221-2-herve.codina@bootlin.comSigned-off-by: Philipp Zabel List of files: /linux-6.15/drivers/misc/Makefile

1e9046e3 - rpmb: add Replay Protected Memory Block (RPMB) subsystem

Wed, 14 Aug 2024 15:35:55 +0000

rpmb: add Replay Protected Memory Block (RPMB) subsystemA number of storage technologies support a specialised hardwarepartition designed to be resistant to replay attacks. The underlyingHW protocols differ but the operations are common. The RPMB partitioncannot be accessed via standard block layer, but by a set of specificRPMB commands. Such a partition provides authenticated and replayprotected access, hence suitable as a secure storage.The initial aim of this patch is to provide a simple RPMB driverinterface which can be accessed by the optee driver to facilitate earlyRPMB access to OP-TEE OS (secure OS) during the boot time.A TEE device driver can claim the RPMB interface, for example, viarpmb_interface_register() or rpmb_dev_find_device(). The RPMB driverprovides a callback to route RPMB frames to the RPMB device accessiblevia rpmb_route_frames().The detailed operation of implementing the access is left to the TEEdevice driver itself.Signed-off-by: Tomas Winkler Signed-off-by: Alex Bennée Signed-off-by: Shyam Saini Signed-off-by: Jens Wiklander Reviewed-by: Linus Walleij Tested-by: Manuel Traut Reviewed-by: Ulf Hansson Reviewed-by: Greg Kroah-Hartman Link: https://lore.kernel.org/r/20240814153558.708365-2-jens.wiklander@linaro.orgSigned-off-by: Ulf Hansson List of files: /linux-6.15/drivers/misc/Makefile

misc: keba: Add basic KEBA CP500 system FPGA supportThe KEBA CP500 system FPGA is a PCIe device, which consists of multipleIP cores. Every IP core has its own auxiliary driver. The cp500 driverregisters an auxiliary device for each device and the correspondingdrivers are loaded by the Linux driver infrastructure.Currently 3 variants of this device exists. Every variant has its ownPCI device ID, which is used to determine the list of available IPcores. In this first version only the auxiliary device for the I2Ccontroller is registered.Besides the auxiliary device registration some other basic functions ofthe FPGA are implemented; e.g, FPGA version sysfs file, keep FPGAconfiguration on reset sysfs file, error message for errors on theinternal AXI bus of the FPGA.Signed-off-by: Gerhard Engleder Link: https://lore.kernel.org/r/20240630194740.7137-2-gerhard@engleder-embedded.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/misc/Makefile

misc: Add a mechanism to detect stalls on guest vCPUsThis driver creates per-cpu hrtimers which are required to do theperiodic 'pet' operation. On a conventional watchdog-core driver, theuserspace is responsible for delivering the 'pet' events by writing tothe particular /dev/watchdogN node. In this case we require a strongthread affinity to be able to account for lost time on a per vCPU.This part of the driver is the 'frontend' which is reponsible fordelivering the periodic 'pet' events, configuring the virtual peripheraland listening for cpu hotplug events. The other part of the driver isan emulated MMIO device which is part of the KVM virtual machinemonitor and this part accounts for lost time by looking at the/proc/{}/task/{}/stat entries.Reviewed-by: Guenter Roeck Reviewed-by: Will Deacon Signed-off-by: Sebastian Ene Link: https://lore.kernel.org/r/20220711081720.2870509-3-sebastianene@google.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/misc/Makefile

Wed, 26 Jan 2022 23:12:37 +0000

misc: open-dice: Add driver to expose DICE data to userspaceOpen Profile for DICE is an open protocol for measured boot compatiblewith the Trusted Computing Group's Device Identifier CompositionEngine (DICE) specification. The generated Compound Device Identifier(CDI) certificates represent the hardware/software combination measuredby DICE, and can be used for remote attestation and sealing.Add a driver that exposes reserved memory regions populated by firmwarewith DICE CDIs and exposes them to userspace via a character device.Userspace obtains the memory region's size from read() and calls mmap()to create a mapping of the memory region in its address space. Themapping is not allowed to be write+shared, giving userspace a guaranteethat the data were not overwritten by another process.Userspace can also call write(), which triggers a wipe of the DICE databy the driver. Because both the kernel and userspace mappings usewrite-combine semantics, all clients observe the memory as zeroed afterthe syscall has returned.Cc: Andrew Scull Cc: Will Deacon Acked-by: Rob Herring Signed-off-by: David Brazdil Link: https://lore.kernel.org/r/20220126231237.529308-3-dbrazdil@google.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/misc/Makefile

That device has two SPI chip selects:The main interface's behaviour depends on the loaded firmwareand is currently unused.The secondary interface can be used to update the firmware usingEzPort protocol. This is implemented by this driver using thekernel's firmware API. The firmware is being flashed intonon-volatile flash memory, so it is enough to flash it onceand not on every boot. Flashing will wear the flash memory(it has a life time of at least 10k programming cycles). Atthe same time only occasional FW updates are expected (like e.g.a BIOS update). Thus the firmware update is triggered via sysfsinstead of doing it in the driver's probe routine like manyother drivers.Signed-off-by: Sebastian Reichel Link: https://lore.kernel.org/r/20210802172309.164365-4-sebastian.reichel@collabora.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/misc/Makefile
