* | License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman2017-11-021-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * powerpc/boot: Fix 64-bit boot wrapper build with non-biarch compilerMichael Ellerman2017-07-281-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Historically the boot wrapper was always built 32-bit big endian, even for 64-bit kernels. That was because old firmwares didn't necessarily support booting a 64-bit image. Because of that arch/powerpc/boot/Makefile uses CROSS32CC for compilation. However when we added 64-bit little endian support, we also added support for building the boot wrapper 64-bit. However we kept using CROSS32CC, because in most cases it is just CC and everything works. However if the user doesn't specify CROSS32_COMPILE (which no one ever does AFAIK), and CC is *not* biarch (32/64-bit capable), then CROSS32CC becomes just "gcc". On native systems that is probably OK, but if we're cross building it definitely isn't, leading to eg: gcc ... -m64 -mlittle-endian -mabi=elfv2 ... arch/powerpc/boot/cpm-serial.c gcc: error: unrecognized argument in option ‘-mabi=elfv2’ gcc: error: unrecognized command line option ‘-mlittle-endian’ make: *** [zImage] Error 2 To fix it, stop using CROSS32CC, because we may or may not be building 32-bit. Instead setup a BOOTCC, which defaults to CC, and only use CROSS32_COMPILE if it's set and we're building for 32-bit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we don't set ARCH incorrectly when calling the boot Makefile, we can use the generic cpp_lds_S rule for converting our zImage.lds.S into zImage.lds. The main advantage of using the generic rule is that it correctly uses if_changed, which means we correctly regenerate the linker script when switching endian.

* powerpc/boot: Add support for XZ compressionOliver O'Halloran2016-09-281-0/+3
| | | | | | | | | | | | | | | This patch adds an option to use XZ compression for the kernel image. Currently this is only enabled for 64-bit Book3S targets, which is roughly equivalent to the platforms that use the kernel's zImage wrapper, and that have been tested. The bulk of the 32-bit platforms and 64-bit BookE use uboot images, which relies on uboot implementing XZ. In future we can enable XZ support for those targets once someone has tested it.

The legazy --no-gzip and -z options are still supported and will set the compression to none and gzip respectively, but they are not documented. Only XZ -6 is used for compression rather than XZ -9. Using compression levels higher than 6 requires the decompressor to build a large (64MB) dictionary when decompressing and some environments cannot satisfy such large allocations (e.g. POWER 6 LPAR partition firmware).

| | | | | | | | | | | | | | | | | The powerpc boot wrapper is potentially compiled with a separate toolchain and/or toolchain flags than the rest of the kernel. The usual case is a 64-bit big endian kernel builds a 32-bit big endian wrapper. The main problem with this is that the wrapper does not have access to the kernel headers (without a lot of gross hacks). To get around this the required headers are copied into the build directory via several sed scripts which rewrite problematic includes. This patch moves these fixups out of the makefile into a separate .sed script file to clean up makefile slightly.

* | powerpc/boot: Add OPAL console to epapr wrappersOliver O'Halloran2016-07-051-2/+2
|/ | | | | | | | | | | | | | | | | | | This patch adds an OPAL console backend to the powerpc boot wrapper so that decompression failures inside the wrapper can be reported to the user. This is important since it typically indicates data corruption in the firmware and other nasty things. Currently this only works when building a little endian kernel. When compiling a 64 bit BE kernel the wrapper is always build 32 bit to be compatible with some 32 bit firmwares. BE support will be added at a later date. Another limitation of this is that only the "raw" type of OPAL console is supported, however machines that provide a hvsi console also provide a raw console so this is not an issue in practice.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code is only slightly modified : entry points now use the FIXUP_ENDIAN trampoline to switch endian order. The 32bit wrapper is kept for big endian kernels and 64bit is enforced for little endian kernels with a PPC64_BOOT_WRAPPER config option. The linker script is generated using the kernel preprocessor flags to make use of the CONFIG_* definitions and the wrapper script is modified to take into account the new elf64ppc format. Finally, the zImage file is compiled as a position independent executable (-pie) which makes it loadable at any address by the firmware.

| | | | | | | | | | | | | | | | | | | | | | | | | | This processor/memory module was mostly used on ATCA blades and before that, on cPCI blades. It wasn't really user friendly, with custom non u-boot bootloaders (powerboot/motload) and no real way to recover corrupted boot flash (which was a common problem). As such, it had its day back before the big ppc --> powerpc move to device trees, and that was largely through commercial BSPs that started to dry up around 2007. Systems using one were largely in a "deploy and sustain" mode, so interest in upgrading to new kernels in the field was nil. Also, requiring 50A, 48V power supplies and a 2'x2'x2' ATCA chassis largely rules out any hobbyist/enthusiast interest. The point of all this, is that we might as well delete the in kernel files relating to this platform. No point in continuing to build it via walking the defconfigs or via linux-next testing.

The MVME5100 is a 6U form factor VME64 computer with: - A single MPC7410 or MPC750 CPU - A HAWK Processor Host Bridge (CPU to PCI) and MultiProcessor Interrupt Controller (MPIC) - Up to 500Mb of onboard memory - A M48T37 Real Time Clock (RTC) and Non-Volatile Memory chip - Two 16550 compatible UARTS - Two Intel E100 Fast Ethernets - Two PCI Mezzanine Card (PMC) Slots - PPCBug Firmware The HAWK PHB/MPIC is compatible with the MPC10x devices. There is no onboard disk support. This is usually provided by installing a PMC in first PMC slot. This patch revives the board support, it was present in early 2.6 series kernels. The board support in those days was by Matt Porter of MontaVista Software. CSC Australia has around 31 of these boards in service. The kernel in use for the boards is based on 2.6.31. The boards are operated without disks from a file server. This patch is based on linux-3.13-rc2 and has been boot tested. Only boards with 512 Mb of memory are known to work.
