Greg Kroah-Hartman	b24413180f	License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

Takashi Iwai	3137497232	ACPI / PMIC: Add opregion driver for Intel Dollar Cove TI PMIC ... This patch adds the opregion driver for Dollar Cove TI PMIC on Intel Cherry Trail devices. The patch is based on the original work by Intel, found at: https://github.com/01org/ProductionKernelQuilts with many cleanups and rewrites. The driver is currently provided only as built-in to follow other PMIC opregion drivers convention. The re-enumeration of devices at probe is required for fixing the issues on HP x2 210 G2. See bug#195689.

Srinivas Pandruvada	eeb2d80d50	ACPI / LPIT: Add Low Power Idle Table (LPIT) support ... Add functionality to read LPIT table, which provides: - Sysfs interface to read residency counters via /sys/devices/system/cpu/cpuidle/low_power_idle_cpu_residency_us /sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us Here the count "low_power_idle_cpu_residency_us" shows the time spent by CPU package in low power state. This is read via MSR interface, which points to MSR for PKG C10. Here the count "low_power_idle_system_residency_us" show the count the system was in low power state. This is read via MMIO interface. This is mapped to SLP_S0 residency on modern Intel systems. This residency is achieved only when CPU is in PKG C10 and all functional blocks are in low power state. It is possible that none of the above counters present or anyone of the counter present or all counters present. For example: On my Kabylake system both of the above counters present. After suspend to idle these counts updated and prints: 6916179 6998564 This counter can be read by tools like turbostat to display. Or it can be used to debug, if modern systems are reaching desired low power state. - Provides an interface to read residency counter memory address This address can be used to get the base address of PMC memory mapped IO. This is utilized by intel_pmc_core driver to print more debug information. In addition, to avoid code duplication to read iomem, removed the read of iomem from acpi_os_read_memory() in osl.c and made a common function acpi_os_read_iomem(). This new function is used for reading iomem in in both osl.c and acpi_lpit.c.

Rajmohan Mani	e13452ac37	ACPI / PMIC: Add TI PMIC TPS68470 operation region driver ... The Kabylake platform coreboot (Chrome OS equivalent of BIOS) has defined 4 operation regions for the TI TPS68470 PMIC. These operation regions are to enable/disable voltage regulators, configure voltage regulators, enable/disable clocks and to configure clocks. This config adds ACPI operation region support for TI TPS68470 PMIC. TPS68470 device is an advanced power management unit that powers a Compact Camera Module (CCM), generates clocks for image sensors, drives a dual LED for flash and incorporates two LED drivers for general purpose indicators. This driver enables ACPI operation region support to control voltage regulators and clocks for the TPS68470 PMIC.

Hans de Goede	2e5a7f7109	ACPI / PMIC: Stop xpower OPRegion handler relying on IIO ... The intel_pmic_xpower code provides an OPRegion handler, which must be available before other drivers using it are loaded, which can only be ensured if both the mfd and opregion drivers are built in, which is why the Kconfig option for intel_pmic_xpower is a bool. The use of IIO is causing trouble for generic distro configs here as distros will typically want to build IIO drivers as modules and there really is no reason to use IIO here. The reading of the ADC value is a single regmap_bulk_read, which is already protected against races by the regmap-lock. This commit removes the use of IIO, allowing distros to enable the driver without needing to built IIO in and also actually simplifies the code.

Mika Westerberg	058dfc7670	ACPI / watchdog: Add support for WDAT hardware watchdog ... Starting from Intel Skylake the iTCO watchdog timer registers were moved to reside in the same register space with SMBus host controller. Not all needed registers are available though and we need to unhide P2SB (Primary to Sideband) device briefly to be able to read status of required NO_REBOOT bit. The i2c-i801.c SMBus driver used to handle this and creation of the iTCO watchdog platform device. Windows, on the other hand, does not use the iTCO watchdog hardware directly even if it is available. Instead it relies on ACPI Watchdog Action Table (WDAT) table to describe the watchdog hardware to the OS. This table contains necessary information about the the hardware and also set of actions which are executed by a driver as needed. This patch implements a new watchdog driver that takes advantage of the ACPI WDAT table. We split the functionality into two parts: first part enumerates the WDAT table and if found, populates resources and creates platform device for the actual driver. The second part is the driver itself. The reason for the split is that this way we can make the driver itself to be a module and loaded automatically if the WDAT table is found. Otherwise the module is not loaded. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Rafael J.

Tomasz Nowicki	88ef16d888	ACPI: I/O Remapping Table (IORT) initial support ... IORT shows representation of IO topology for ARM based systems. It describes how various components are connected together on parent-child basis e.g. PCI RC -> SMMU -> ITS. Also see IORT spec. http://infocenter.arm.com/help/topic/com.arm.doc.den0049b/DEN0049B_IO_Remapping_Table.pdf Initial support allows to detect IORT table presence and save its root pointer obtained through acpi_get_table(). The pointer validity depends on acpi_gbl_permanent_mmap because if acpi_gbl_permanent_mmap is not set while using IORT nodes we would dereference unmapped pointers. For the aforementioned reason call acpi_iort_init() from acpi_init() which guarantees acpi_gbl_permanent_mmap to be set at that point. Add generic helpers which are helpful for scanning and retrieving information from IORT table content. List of the most important helpers: - iort_find_dev_node() finds IORT node for a given device - iort_node_map_rid() maps device RID and returns IORT node which provides final translation IORT support is placed under drivers/acpi/arm64/ new directory due to its ARM64 specific nature.

Also for legacy systems with only _PSS, we shouldn't bail out if acpi_cppc_processor_probe() fails, if ACPI_CPU_FREQ_PSS is also defined.

Linus Torvalds	f0c98ebc57	libnvdimm for 4.8 ... 1/ Replace pcommit with ADR / directed-flushing: The pcommit instruction, which has not shipped on any product, is deprecated. Instead, the requirement is that platforms implement either ADR, or provide one or more flush addresses per nvdimm. ADR (Asynchronous DRAM Refresh) flushes data in posted write buffers to the memory controller on a power-fail event. Flush addresses are defined in ACPI 6.x as an NVDIMM Firmware Interface Table (NFIT) sub-structure: "Flush Hint Address Structure". A flush hint is an mmio address that when written and fenced assures that all previous posted writes targeting a given dimm have been flushed to media. 2/ On-demand ARS (address range scrub): Linux uses the results of the ACPI ARS commands to track bad blocks in pmem devices. When latent errors are detected we re-scrub the media to refresh the bad block list, userspace can also request a re-scrub at any time. 3/ Support for the Microsoft DSM (device specific method) command format. 4/ Support for EDK2/OVMF virtual disk device memory ranges. 5/ Various fixes and cleanups across the subsystem. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJXmXBsAAoJEB7SkWpmfYgCEwwP/1IOt9ocP+iHLMDH9KE7VaTZ NmUDR+Zy6g5cRQM7SgcuU5BXUcx+OsSrSrUTVF1cW994o9Gbz1mFotkv0ZAsPcYY ZVRQxo2oqHrssyOcg+PsgKWiXn68rJOCgmpEyzaJywl5qTMst7pzsT1s1f7rSh6h trCf4VaJJwxZR8fARGtlHUnnhPe2Orp99EZRKEWprAsIv2kPuWpPHSjRjuEgN1JG KW8AYwWqFTtiLRUk86I4KBB0wcDrfctsjgN9Ogd6+aHyQBRnVSr2U+vDCFkC8KLu qiDCpYp+yyxBjclnljz7tRRT3GtzfCUWd4v2KVWqgg2IaobUc0Lbukp/rmikUXQP WLikT2OCQ994eFK5OX3Q3cIU/4j459TQnof8q14yVSpjAKrNUXVSR5puN7Hxa+V7 41wKrAsnsyY1oq+Yd/rMR8VfH7PHx3bFkrmRCGZCufLX1UQm4aYj+sWagDKiV3yA DiudghbOnhfurfGsnXUVw7y7GKs+gNWNBmB6ndAD6ZEHmKoGUhAEbJDLCc3DnANl b/2mv1MIdIcC1DlCmnbbcn6fv6bICe/r8poK3VrCK3UgOq/EOvKIWl7giP+k1JuC 6DdVYhlNYIVFXUNSLFAwz8OkLu8byx7WDm36iEqrKHtPw+8qa/2bWVgOU6OBgpjV cN3edFVIdxvZeMgM5Ubq =xCBG -----END PGP SIGNATURE----- Merge tag 'libnvdimm-for-4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm updates from Dan Williams: - Replace pcommit with ADR / directed-flushing.

Tomasz Nowicki	935c760ec8	PCI/ACPI: Add generic MCFG table handling ... On ACPI systems that support memory-mapped config space access, i.e., ECAM, the PCI Firmware Specification says the OS can learn where the ECAM space is from either: - the static MCFG table (for non-hotpluggable bridges), or - the _CBA method (for hotpluggable bridges) The current MCFG table handling code cannot be easily generalized owing to x86-specific quirks, which makes it hard to reuse on other architectures. Implement generic MCFG handling from scratch, including: - Simple MCFG table parsing (via pci_mmcfg_late_init() as in current x86) - MCFG region lookup for a (domain, bus_start, bus_end) tuple [bhelgaas: changelog] Signed-off-by: Tomasz Nowicki <tn@semihalf.com> Signed-off-by: Jayachandran C <jchandra@broadcom.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com>	2016-06-10 18:27:59 -05:00

Mark Brown	46bcc6b1f3	ACPI / ARM64: Remove EXPERT dependency for ACPI on ARM64 ... When ACPI was originally merged for arm64 it had only been tested on emulators and not on real physical platforms and no platforms were relying on it. This meant that there were concerns that there might be serious issues attempting to use it on practical systems so it had a dependency on EXPERT added to warn people that it was in an early stage of development with very little practical testing. Since then things have moved on a bit. We have seen people testing on real hardware and now have people starting to produce some platforms (the most prominent being the 96boards Cello) which only have ACPI support and which build and run to some useful extent with mainline. This is not to say that ACPI support or support for these systems is completely done, there are still areas being worked on such as PCI, but at this point it seems that we can be reasonably sure that ACPI will be viable for use on ARM64 and that the already merged support works for the cases it handles. For the AMD Seattle based platforms support outside of PCI has been fairly complete in mainline a few releases now. This is also not to say that we don't have vendors working with ACPI who are trying do things that we would not consider optimal but it does not appear that the EXPERT dependency is having a substantial impact on these vendors. Given all this it seems that at this point the EXPERT dependency mainly creates inconvenience for users with systems that are doing the right thing and gets in the way of including the ACPI code in the testing that people are doing on mainline. Removing it should help our ongoing testing cover those platforms with only ACPI support and help ensure that when ACPI code is merged any problems it causes for other users are more easily discovered.

Mark Brown	6df795ff13	ACPI / ARM64: Don't enable ACPI by default on ARM64 ... If ACPI is selectable it is enabled by default. This is a good choice for architectures where the overwhelming majority of systems use ACPI like x86 and IA-64 but is less clear for architectures where it's less common like ARM64. Change the default selection so that it's only done explicitly on those architectures where ACPI is universally used.

Lv Zheng	5d8813271f	ACPI / tables: Convert initrd table override to table upgrade mechanism ... This patch converts the initrd table override mechanism to the table upgrade mechanism by restricting its usage to the tables released with compatibility and more recent revision. This use case has been encouraged by the ACPI specification: 1. OEMID: An OEM-supplied string that identifies the OEM. 2. OEM Table ID: An OEM-supplied string that the OEM uses to identify the particular data table. This field is particularly useful when defining a definition block to distinguish definition block functions. OEM assigns each dissimilar table a new OEM Table Id. 3. OEM Revision: An OEM-supplied revision number. Larger numbers are assumed to be newer revisions. For OEMs, good practices will ensure consistency when assigning OEMID and OEM Table ID fields in any table. The intent of these fields is to allow for a binary control system that support services can use. Because many support function can be automated, it is useful when a tool can programatically determine which table release is a compatible and more recent revision of a prior table on the same OEMID and OEM Table ID. The facility can now be used by the vendors to upgrade wrong tables for bug fixing purpose, thus lockdep disabling taint is not suitable for it and it should be a default 'y' option to implement the spec encouraged use case. Note that, by implementing table upgrade inside of ACPICA itself, it is possible to remove acpi_table_initrd_override() and tables can be upgraded by acpi_install_table() automatically. Though current ACPICA impelentation hasn't implemented this, this patched changes the table flag setting timing to allow this to be implemented in ACPICA without changing the code here. Documentation of initrd override mechanism is upgraded accordingly. Original-by: Octavian Purdila <octavian.purdila@intel.com> Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J.

IO flush support acpi_os_notify_command_complete() and acpi_os_wait_command_ready() can be used by acpi_dbg module to implement .flush() filesystem operation. While this patch doesn't go that far.
