powerpc/sysdev: drop simple gpioThere is a config item CONFIG_SIMPLE_GPIO whichprovides simple memory mapped GPIOs specific to powerpc.However, the only platform which selects this option ismpc5200, and this platform doesn't use it.There are three boards calling simple_gpiochip_init(), butas they don't select CONFIG_SIMPLE_GPIO, this is just a nop.Simple_gpio is just redundant with the generic MMIO GPIOdriver which can be found in driver/gpio/ and selected viaCONFIG_GPIO_GENERIC_PLATFORM, so drop simple_gpio driver.Signed-off-by: Christophe Leroy Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/bf930402613b41b42d0441b784e0cc43fc18d1fb.1572529632.git.christophe.leroy@c-s.fr List of files: /linux-6.15/arch/powerpc/sysdev/Makefile

powerpc: Add -Werror at arch/powerpc levelBack when I added -Werror in commit ba55bd74360e ("powerpc: Addconfigurable -Werror for arch/powerpc") I did it by adding it to mostof the arch Makefiles.At the time we excluded math-emu, because apparently it didn't buildcleanly. But that seems to have been fixed somewhere in the interim.So move the -Werror addition to the top-level of the arch, this savesus from repeating it in every Makefile and means we won't forget toadd it to any new sub-dirs.Signed-off-by: Michael Ellerman List of files: /linux-6.15/arch/powerpc/sysdev/Makefile

Thu, 02 Nov 2017 23:56:32 +0000

powerpc/cell: Remove axonram driverThe QS21/22 IBM Cell blades had a southbridge chip called Axon. Thiscould have DDR DIMMs attached to it, though they were not directlyusable as RAM, instead they could be used as some sort of buffer, ifapplications were written specifically to use the block deviceprovided by the driver.Although the driver supposedly had direct access support, it wasapparently never tested (see commit 91117a20245b ("axonram: Fix bug indirect_access")).These machines have not been available for over 5 years, and werenever widely in use. It seems highly unlikely anyone is using thisdriver.In general we're happy to leave old drivers in the tree, but becauseDAX is involved this driver is caught up in the ongoing work in thatarea, but none of the DAX folks are able to test it.So remove the driver, if any one *is* using it, we'll be happy to putit back.Signed-off-by: Michael Ellerman List of files: /linux-6.15/arch/powerpc/sysdev/Makefile

b2441318 - License cleanup: add SPDX GPL-2.0 license identifier to files with no license

Wed, 01 Nov 2017 14:07:57 +0000

License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseMany source files in the tree are missing licensing information, whichmakes it harder for compliance tools to determine the correct license.By default all files without license information are under the defaultlicense 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 bindingshorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart andPhilippe Ombredanne.How this work was done:Patches were generated and checked against linux-4.14-rc6 for a subset ofthe 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 caseswhere non-standard license headers were used, and references to licensehad to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied toa file was done in a spreadsheet of side by side results from of theoutput of two independent scanners (ScanCode & Windriver) producing SPDXtag:value files created by Philippe Ombredanne. Philippe prepared thebase 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 filesassessed. Kate Stewart did a file by file comparison of the scannerresults in the spreadsheet to determine which SPDX license identifier(s)to be applied to the file. She confirmed any determination that was notimmediately 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 licenseidentifiers 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 thespreadsheet to determine the SPDX license identifiers to apply to thesource files by Kate, Philippe, Thomas and, in some cases, confirmationby lawyers working with the Linux Foundation.Kate also obtained a third independent scan of the 4.13 code base fromFOSSology, and compared selected files where the other two scannersdisagreed against that SPDX file, to see if there was new insights. TheWindriver scanner is based on an older version of FOSSology in part, sothey are related.Thomas did random spot checks in about 500 files from the spreadsheetsfor the uapi headers and agreed with SPDX license identifier in thefiles he inspected. For the non-uapi files Thomas did random spot checksin about 15000 files.In initial set of patches against 4.14-rc6, 3 files were found to havecopy/paste license identifier errors, and have been fixed to reflect thecorrect identifier.Additionally Philippe spent 10 hours this week doing a detailed manualinspection and review of the 12,461 patched files from the initial patchversion 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 correctThis produced a worksheet with 20 files needing minor correction. Thisworksheet was then exported into 3 different .csv files for thedifferent types of files to be modified.These .csv files were then reviewed by Greg. Thomas wrote a script toparse the csv files and add the proper SPDX tag to the file, in theformat that the file expected. This script was further refined by Gregbased on the output to detect more types of files automatically and todistinguish between header and source .c files (which need differentcomment types.) Finally Greg ran the script using the .csv files togenerate the patches.Reviewed-by: Kate Stewart Reviewed-by: Philippe Ombredanne Reviewed-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/arch/powerpc/sysdev/Makefile

powerpc/xive: Native exploitation of the XIVE interrupt controllerThe XIVE interrupt controller is the new interrupt controllerfound in POWER9. It supports advanced virtualization capabilitiesamong other things.Currently we use a set of firmware calls that simulate the old"XICS" interrupt controller but this is fairly inefficient.This adds the framework for using XIVE along with a nativebackend which OPAL for configuration. Later, a backend allowingthe use in a KVM or PowerVM guest will also be provided.This disables some fast path for interrupts in KVM when XIVE isenabled as these rely on the firmware emulation code which is nolonger available when the XIVE is used natively by Linux.A latter patch will make KVM also directly exploit the XIVE, thusrecovering the lost performance (and more).Signed-off-by: Benjamin Herrenschmidt [mpe: Fixup pr_xxx("XIVE:"...), don't split pr_xxx() strings, tweak Kconfig so XIVE_NATIVE selects XIVE and depends on POWERNV, fix build errors when SMP=n, fold in fixes from Ben: Don't call cpu_online() on an invalid CPU number Fix irq target selection returning out of bounds cpu# Extra sanity checks on cpu numbers ]Signed-off-by: Michael Ellerman List of files: /linux-6.15/arch/powerpc/sysdev/Makefile
