docs: kbuild: convert docs to ReST and rename to *.rst The kbuild documentation clearly shows that the documents there are written at different times: some use markdown, some use their own peculiar logic to split sections. Convert everything to ReST without affecting too much the author's style and avoiding adding uneeded markups. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

menu "Firmware Drivers"
firmware: arm_scmi: add basic driver infrastructure for SCMI The SCMI is intended to allow OSPM to manage various functions that are provided by the hardware platform it is running on, including power and performance functions. SCMI provides two levels of abstraction, protocols and transports. Protocols define individual groups of system control and management messages. A protocol specification describes the messages that it supports. Transports describe the method by which protocol messages are communicated between agents and the platform. This patch adds basic infrastructure to manage the message allocation, initialisation, packing/unpacking and shared memory management.

ARM System Control and Management Interface (SCMI) protocol is a
set of operating system-independent software interfaces that are
used in system management. SCMI is extensible and currently provides
interfaces for: Discovery and self-description of the interfaces
it supports, Power domain management which is the ability to place
a given device or domain into the various power-saving states that
it supports, Performance management which is the ability to control
the performance of a domain that is composed of compute engines
such as application processors and other accelerators, Clock
management which is the ability to set and inquire rates on platform
managed clocks and Sensor management which is the ability to read
sensor data, and be notified of sensor value.
This protocol library provides interface for all the client drivers
making use of the features offered by the SCMI.

A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

If your firmware supplies the HCDP table, and you want to

device, it will become the console automatically. Otherwise,
you must specify the "console=hcdp" kernel boot argument.

on how the driver discovers devices.

DMI-based module autoloading The patch below adds DMI/SMBIOS based module autoloading to the Linux kernel. The idea is to load laptop drivers automatically (and other drivers which cannot be autoloaded otherwise), based on the DMI system identification information of the BIOS. Right now most distros manually try to load all available laptop drivers on bootup in the hope that at least one of them loads successfully. This patch does away with all that, and uses udev to automatically load matching drivers on the right machines. Basically the patch just exports the DMI information that has been parsed by the kernel anyway to userspace via a sysfs device /sys/class/dmi/id and makes sure that proper modalias attributes are available. Besides adding the "modalias" attribute it also adds attributes for a few other DMI fields which might be useful for writing udev rules. This patch is not an attempt to export the entire DMI/SMBIOS data to userspace. We already have "dmidecode" which parses the complete DMI info from userspace. The purpose of this patch is machine model identification and good udev integration. To take advantage of DMI based module autoloading, a driver should export one or more MODULE_ALIAS fields similar to these: MODULE_ALIAS("dmi:*:svnMICRO-STARINT'LCO.,LTD:pnMS-1013:pvr0131*:cvnMICRO-STARINT'LCO.,LTD:ct10:*"); MODULE_ALIAS("dmi:*:svnMicro-StarInternational:pnMS-1058:pvr0581:rvnMSI:rnMS-1058:*:ct10:*"); MODULE_ALIAS("dmi:*:svnMicro-StarInternational:pnMS-1412:*:rvnMSI:rnMS-1412:*:cvnMICRO-STARINT'LCO.,LTD:ct10:*"); MODULE_ALIAS("dmi:*:svnNOTEBOOK:pnSAM2000:pvr0131*:cvnMICRO-STARINT'LCO.,LTD:ct10:*"); These lines are specific to my msi-laptop.c driver. They are basically just a concatenation of a few carefully selected DMI fields with all potentially bad characters stripped. Besides laptop drivers, modules like "hdaps", the i2c modules and the hwmon modules are good candidates for "dmi:" MODULE_ALIAS lines. Besides merely exporting the DMI data via sysfs the patch adds support for a few more DMI fields. Especially the CHASSIS fields are very useful to identify different laptop modules. The patch also adds working MODULE_ALIAS lines to my msi-laptop.c driver. I'd like to thank Kay Sievers for helping me to clean up this patch for posting it on lkml.

firmware: Basic dmi-sysfs support Introduce a new module "dmi-sysfs" that exports the broken out entries of the DMI table through sysfs. Entries are enumerated via dmi_walk() on module load, and are populated as kobjects rooted at /sys/firmware/dmi/entries. Entries are named "<type>-<instance>", where: <type> : is the type of the entry, and <instance> : is the ordinal count within the DMI table of that entry type. This instance is used in lieu the DMI entry's handle as no assurances are made by the kernel that handles are unique. All entries export the following attributes: length : The length of the formatted portion of the entry handle : The handle given to this entry by the firmware raw : The raw bytes of the entire entry, including the formatted portion, the unformatted (strings) portion, and the two terminating nul characters. type : The DMI entry type instance : The ordinal instance of this entry given its type. position : The position ordinal of the entry within the table in its entirety. Entries in dmi-sysfs are kobject backed members called "struct dmi_sysfs_entry" and belong to dmi_kset. They are threaded through entry_list (protected by entry_list_lock) so that we can find them at cleanup time.

firmware/dmi_scan: generalize for use by other archs This patch makes a couple of changes to the SMBIOS/DMI scanning code so it can be used on other archs (such as ARM and arm64): (a) wrap the calls to ioremap()/iounmap(), this allows the use of a flavor of ioremap() more suitable for random unaligned access; (b) allow the non-EFI fallback probe into hardcoded physical address 0xF0000 to be disabled.

firmware: Add Turris Mox rWTM firmware driver This adds a driver to communicate with the firmware running on the secure processor of the Turris Mox router, enabling the kernel to retrieve true random numbers from the Entropy Bit Generator and to read some information burned into eFuses when device was manufactured: and to sign messages with the ECDSA private key burned into each Turris Mox device when manufacturing. This also adds support to read other information burned into eFuses: - serial number - board version - MAC addresses - RAM size - ECDSA public key (this is not read directly from eFuses, rather it is computed by the firmware as pair to the burned private key) The source code of the firmware is open source and can be found at https://gitlab.labs.nic.cz/turris/mox-boot-builder/tree/master/wtmi The firmware is also able to, on demand, sign messages with the burned ECDSA private key, but since Linux's akcipher API is not yet stable (and therefore not exposed to userspace via netlink), this functionality is not supported yet.

This driver communicates with the firmware on the Cortex-M3 secure
processor of the Turris Mox router. Enable if you are building for
Turris Mox, and you will be able to read the device serial number and
other manufacturing data and also utilize the Entropy Bit Generator
for hardware random number generation.
ARM: 8478/2: arm/arm64: add arm-smccc Adds helpers to do SMC and HVC based on ARM SMC Calling Convention. CONFIG_HAVE_ARM_SMCCC is enabled for architectures that may support the SMC or HVC instruction. It's the responsibility of the caller to know if the SMC instruction is supported by the platform. This patch doesn't provide an implementation of the declared functions. Later patches will bring in implementations and set CONFIG_HAVE_ARM_SMCCC for ARM and ARM64 respectively.

MIPS: BCM47xx: Move NVRAM driver to the drivers/firmware/ After Broadcom switched from MIPS to ARM for their home routers we need to have NVRAM driver in some common place (not arch/mips/). As explained in Kconfig, this driver is responsible for parsing SoC configuration data that is passed to the kernel in flash from the bootloader firmware called "CFE". We were thinking about putting it in bus directory, however there are two possible buses for MIPS: drivers/ssb/ and drivers/bcma/. So this won't fit there and this is why I would like to move this driver to the drivers/firmware/.

driver: Google EFI SMI The "gsmi" driver bridges userland with firmware specific routines for accessing hardware. Currently, this driver only supports NVRAM and eventlog information. Deprecated functions have been removed from the driver, though their op-codes are left in place so that they are not re-used. This driver works by trampolining into the firmware via the smi_command outlined in the FADT table. Three protocols are used due to various limitations over time, but all are included herein. This driver should only ever load on Google boards, identified by either a "Google, Inc." board vendor string in DMI, or "GOOGLE" in the OEM strings of the FADT ACPI table.

efivars: Move pstore code into the new EFI directory 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.

firmware: tegra: Add IVC library The Inter-VM communication (IVC) is a communication protocol which is designed for interprocessor communication (IPC) or the communication between the hypervisor and the virtual machine with a guest OS. Message channels are used to communicate between processors. They are backed by DRAM or SRAM, so care must be taken to maintain coherence of data. The IVC library maintains memory-based descriptors for the transmission and reception channels as well as the data coherence of the counter and payload. Clients, such as the driver for the BPMP firmware, can use the library to exchange messages with remote processors.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
