1019fa48 - uio: pruss: Remove this driver

Wed, 10 Apr 2024 14:48:03 +0000

uio: pruss: Remove this driverThis UIO driver was used to control the PRU processors found on variousTI SoCs. It was created before the Remoteproc framework, but now withthat we have a standard way to program and manage the PRU processors.The proper PRU Remoteproc driver should be used instead of this driver.This driver only supported the original class of PRUSS (OMAP-L1xx /AM17xx / AM18xx / TMS320C674x / DA8xx) but when these platforms wereswitched to use Device Tree the support for DT was not added to thisdriver and so it is now unused/unusable. Support for these platformscan be added to the proper PRU Remoteproc driver if ever needed.Remove this driver.Signed-off-by: Andrew Davis Link: https://lore.kernel.org/r/20240410144803.126831-1-afd@ti.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/uio/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/drivers/uio/Makefile

0a0c3b5a - Add new uio device for dynamic memory allocation

Tue, 25 Sep 2012 06:09:11 +0000

Add new uio device for dynamic memory allocationThis device extends the uio_pdrv_genirq driver to provide limiteddynamic memory allocation for UIO devices. This allows UIO devicesto use CMA and IOMMU allocated memory regions. This driver is basedon the uio_pdrv_genirq driver and provides the same generic interrupthandling capabilities. Like uio_prdv_genirq,a fixed number of memory regions, defined in the platform device's.resources field are exported to userpace. This driver adds the abilityto export additional regions whose number and size are known at boot time,but whose memory is not allocated until the uio device file is opened forthe first time. When the device file is closed, the allocated memory blockis freed. Physical (DMA) addresses for the dynamic regions are provided tothe userspace via /sys/class/uio/uioX/maps/mapY/addr in the same way asstatic addresses are when the uio device file is open, when no processesare holding the device file open, the address returned to userspace isDMA_ERROR_CODE.Signed-off-by: Damian Hobson-Garcia Signed-off-by: "Hans J.

uio: add generic driver for PCI 2.3 devicesThis adds a generic uio driver that can bind to any PCI device. Firstuser will be virtualization where a qemu userspace process needs to giveguest OS access to the device.Interrupts are handled using the Interrupt Disable bit in the PCIcommand register and Interrupt Status bit in the PCI status register.All devices compliant to PCI 2.3 (circa 2002) and all compliant PCIExpress devices should support these bits. Driver detects this support,and won't bind to devices which do not support the Interrupt Disable Bitin the command register.It's expected that more features of interest to virtualization will beadded to this driver in the future.

This driver is very similar to the regularUIO platform driver, but is only suitable for devices that areconnected to the interrupt controller using unique interrupt lines.The uio_pdrv_genirq driver includes generic interrupt handling codewhich disables the serviced interrupt in the interrupt controllerand makes the user space driver responsible for acknowledging theinterrupt in the device and reenabling the interrupt in the interruptcontroller.Shared interrupts are not supported since the in-kernel interrupthandler will disable the interrupt line in the interrupt controller,and in a shared interrupt configuration this will stop other devicesfrom delivering interrupts.Signed-off-by: Magnus Damm Signed-off-by: Hans J.

UIO: Implement a UIO interface for the SMX CryptengineThis patch implements a UIO interface for the SMX Cryptengine.The Cryptengine found on the Nias Digital SMX board is best suitedfor a UIO interface. It is not wired in to the cryptographic APIas the engine handles it's own keys, algorithms, everything. Allthat we know about is that if there's room in the buffer, you canwrite data to it and when there's data ready, you read it out again.There isn't necessarily even any direct correlation between datagoing in and data coming out again, the engine may consume orgenerate data all on its own.This driver is for proprietary hardware but we're always told tosubmit the drivers anyway; here you are. :-)This is version 4 of this patch and addresses all issues raised byHans-Jürgen Koch and Paul Mundt in their reviews. Slightly alteredis Paul's suggestion to use DRV_NAME and DRV_VERSION as the UIOversion and name. While at the moment they are the same, thereis no reason for them to stay that way. Nevertheless we now atleast provide a MODULE_VERSION macro to keep modinfo happy.Signed-off-by: Ben Nizette Acked-by: Paul Mundt Signed-off-by: Hans J Koch Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/uio/Makefile

I tested it on a Kontron CPX board, and Thomas reviewedit.You can find the user space part here:http://www.osadl.org/projects/downloads/UIO/user/cif-0.1.0.tar.gzNotes: cif_api.c is the main file you want to look at. It contains thefunctions to open, close, mmap and so on. cif_dps.c adds functionsspecific to Profibus cards, and cif_dn.c contains functions forDeviceNet cards. cif.c is a universal playground, it's just a smalltest program. The user space part of this UIO driver is still work inprogress, and not everything is tested yet. At the moment, the thread incif_api.c contains some code that artificially makes the card generateinterrupts, this was added for testing and will be removed later. Butthe driver already contains all the functions needed for usefuloperation, so it gives a good idea of how such a thing looks like.For comparison, here's what you get from the manufacturer(www.hilscher.com) when you ask for a Linux 2.6 driver:http://www.tglx.de/private/hjk/cif-orig-2.6.tar.bz2WARNING: Don't look at the code for too long, you might become sick :-)Signed-off-by: Hans-Jürgen Koch Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/uio/Makefile
