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.

arm64: psci: factor invocation code to drivers To enable sharing with arm, move the core PSCI framework code to drivers/firmware. This results in a minor gain in lines of code, but this will quickly be amortised by the removal of code currently duplicated in arch/arm.

firmware: add support for ARM System Control and Power Interface(SCPI) protocol This patch adds support for System Control and Power Interface (SCPI) Message Protocol used between the Application Cores(AP) and the System Control Processor(SCP). The MHU peripheral provides a mechanism for inter-processor communication between SCP's M3 processor and AP. SCP offers control and management of the core/cluster power states, various power domain DVFS including the core/cluster, certain system clocks configuration, thermal sensors and many others. This protocol driver provides interface for all the client drivers using SCPI to make use of the features offered by the SCP.

Currently all three arches compile it from arch/i386, which means that ia64 and x86_64 depend on things in arch/i386 that they wouldn't otherwise care about. This is simply "mv arch/i386/kernel/dmi_scan.c drivers/firmware/" (removing trailing whitespace) and the associated Makefile changes.

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.

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. Patch is against Linus' current GIT HEAD. Should probably apply to older kernels as well without modification.

sysfs: add /sys/firmware/memmap This patch adds /sys/firmware/memmap interface that represents the BIOS (or Firmware) provided memory map. The tree looks like: /sys/firmware/memmap/0/start (hex number) end (hex number) type (string) ... /1/start end type With the following shell snippet one can print the memory map in the same form the kernel prints itself when booting on x86 (the E820 map). --------- 8< -------------------------- #!/bin/sh cd /sys/firmware/memmap for dir in * ; do start=$(cat $dir/start) end=$(cat $dir/end) type=$(cat $dir/type) printf "%016x-%016x (%s)\n" $start $[ $end +1] "$type" done --------- >8 -------------------------- That patch only provides the needed interface: 1. The sysfs interface. 2. The structure and enumeration definition. 3. The function firmware_map_add() and firmware_map_add_early() that should be called from architecture code (E820/EFI, for example) to add the contents to the interface. If the kernel is compiled without CONFIG_FIRMWARE_MEMMAP, the interface does nothing without cluttering the architecture-specific code with #ifdef's. The purpose of the new interface is kexec: While /proc/iomem represents the *used* memory map (e.g. modified via kernel parameters like 'memmap' and 'mem'), the /sys/firmware/memmap tree represents the unmodified memory map provided via the firmware. So kexec can: - use the original memory map for rebooting, - use the /proc/iomem for setting up the ELF core headers for kdump case that should only represent the memory of the system. The patch has been tested on i386 and x86_64.

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. This logic happens in gsmi_system_valid().

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/.

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.

x86/efi: Don't select EFI from certain special ACPI drivers Commit 7ea6c6c1 ("Move cper.c from drivers/acpi/apei to drivers/firmware/efi") results in CONFIG_EFI being enabled even when the user doesn't want this. Since ACPI APEI used to build fine without UEFI (and as far as I know also has no functional depency on it), at least in that case using a reverse dependency is wrong (and a straight one isn't needed). Whether the same is true for ACPI_EXTLOG I don't know - if there is a functional dependency, it should depend on EFI rather than selecting it. It certainly has (currently) no build dependency. Adjust Kconfig and build logic so that the bad dependency gets avoided.
