246a1c4c - ata: pata_parport: add driver (PARIDE replacement)

Mon, 23 Jan 2023 19:09:54 +0000

ata: pata_parport: add driver (PARIDE replacement)The pata_parport is a libata-based replacement of the old PARIDEsubsystem - driver for parallel port IDE devices.It uses the original paride low-level protocol drivers but does notneed the high-level drivers (pd, pcd, pf, pt, pg). The IDE devicesbehind parallel port adapters are handled by the ATA layer.This will allow paride and its high-level drivers to be removed.Unfortunately, libata drivers cannot sleep so pata_parport claimsparport before activating the ata host and keeps it claimed (andprotocol connected) until the ata host is removed. This means thatno devices can be chained (neither other pata_parport devices nora printer).paride and pata_parport are mutually exclusive because the compiledprotocol drivers are incompatible.Tested with: - Imation SuperDisk LS-120 and HP C4381A (EPAT) - Freecom Parallel CD (FRPW) - Toshiba Mobile CD-RW 2793008 w/Freecom Parallel Cable rev.903 (FRIQ) - Backpack CD-RW 222011 and CD-RW 19350 (BPCK6)The following bugs in low-level protocol drivers were found and willbe fixed later:Note: EPP-32 mode is buggy in EPAT - and also in all other protocoldrivers - they don't handle non-multiple-of-4 block transferscorrectly. This causes problems with LS-120 drive.There is also another bug in EPAT: EPP modes don't work unless a 4-bitor 8-bit mode is used first (probably some initialization missing?).Once the device is initialized, EPP works until power cycle.So after device power on, you have to:echo "parport0 epat 0" >/sys/bus/pata_parport/new_deviceecho pata_parport.0 >/sys/bus/pata_parport/delete_deviceecho "parport0 epat 4" >/sys/bus/pata_parport/new_device(autoprobe will initialize correctly as it tries the slowest modesfirst but you'll get the broken EPP-32 mode)Note: EPP modes are buggy in FRPW, only modes 0 and 1 work.Signed-off-by: Ondrej Zary Reviewed-by: Christoph Hellwig Reviewed-by: Hannes Reinecke Acked-by: Jens Axboe Signed-off-by: Damien Le Moal List of files: /linux-6.15/drivers/ata/Makefile

33629d35 - ata: ahci: Add DWC AHCI SATA controller support

Fri, 09 Sep 2022 19:36:17 +0000

ata: ahci: Add DWC AHCI SATA controller supportSynopsys AHCI SATA controller can work pretty under with the genericAHCI-platform driver control. But there are vendor-specific peculiaritieswhich can tune the device performance up and which may need to be fixed upfor proper device functioning. In addition some DWC AHCI-based controllersmay require small platform-specific fixups, so adding them in the genericAHCI driver would have ruined the code simplicity. Shortly speaking inorder to keep the generic AHCI-platform code clean and have DWC AHCISATA-specific features supported we suggest to add a dedicated DWC AHCISATA device driver. Aside with the standard AHCI-platform resourcesgetting, enabling/disabling and the controller registration the new driverperforms the next actions.First of all there is a way to verify whether the HBA/ports capabilitiesactivated in OF are correct. Almost all features availability is reflectedin the vendor-specific parameters registers. So the DWC AHCI driver doesthe capabilities sanity check based on the corresponding fields state.Secondly if either the Command Completion Coalescing or the Device Sleepfeature is enabled the DWC AHCI-specific internal 1ms timer must be fixedin accordance with the application clock signal frequency. In particularthe timer value must be set to be Fapp * 1000. Normally the SoC designerspre-configure the TIMER1MS register to contain a correct value by default.But the platforms can support the application clock rate change. If thathappens the 1ms timer value must be accordingly updated otherwise thedependent features won't work as expected. In the DWC AHCI driver wesuggest to rely on the "aclk" reference clock rate to set the timerinterval up. That clock source is supposed to be the AHCI SATA applicationclock in accordance with the DT bindings.Finally DWC AHCI SATA controller AXI/AHB bus DMA-engine can be tuned up totransfer up to 1024 * FIFO words at a time by setting the Tx/Rxtransaction size in the DMA control register. The maximum value depends onthe DMA data bus and AXI/AHB bus maximum burst length. In most of thecases it's better to set the maximum possible value to reach the best AHCISATA controller performance. But sometimes in order to improve the systeminterconnect responsiveness, transferring in smaller data chunks may bemore preferable. For such cases and for the case when the default valuedoesn't provide the best DMA bus performance we suggest to use the newHBA-port specific DT-properties "snps,{tx,rx}-ts-max" to tune the DMAtransactions size up.After all the settings denoted above are handled the DWC AHCI SATA driverproceeds further with the standard AHCI-platform host initializations.Note since DWC AHCI controller is now have a dedicated driver we candiscard the corresponding compatible string from the ahci-platform.cmodule. The same concerns "snps,spear-ahci" compatible string, which isalso based on the DWC AHCI IP-core.Signed-off-by: Serge Semin Reviewed-by: Hannes Reinecke Signed-off-by: Damien Le Moal List of files: /linux-6.15/drivers/ata/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/ata/Makefile
