5a4f2040 - ath9k: add loader for AR92XX (and older) pci(e)

Fri, 05 Jul 2019 17:53:13 +0000

ath9k: add loader for AR92XX (and older) pci(e)Atheros cards with a AR92XX generation (and older) chip usuallystore their pci(e) initialization vectors on an external eeprom chip.However these chips technically don't need the eeprom chip attached,the AR9280 Datasheet in section "6.1.2 DEVICE_ID" describes that"... if the EEPROM content is not valid, a value of 0xFF1C returnswhen read from the register". So, they will show up on the system'spci bus. However in that state, ath9k can't load, since it relieson having the correct pci-id, otherwise it doesn't know what chip itactually is. This happens on many embedded devices like routersand accesspoint since they want to keep the BOM low and store thepci(e) initialization vectors together with the calibration dataon the system's FLASH, which is out of reach of the ath9k chip.Furthermore, Some devices (like the Cisco Meraki Z1 Cloud ManagedTeleworker Gateway) need to be able to initialize the PCIe wifi device.Normally, this should be done as a pci quirk during the early stages ofbooting linux. However, this isn't possible for devices which have theinit code for the Atheros chip stored on NAND in an UBI volume.Hence, this module can be used to initialize the chip when theuser-space is ready to extract the init code.Martin Blumenstingl prodived the following fixes:owl-loader: add support for OWL emulation PCI devicesowl-loader: don't re-scan the bus when ath9k_pci_fixup failedowl-loader: use dev_* instead of pr_* logging functionsowl-loader: auto-generate the eeprom filename as fallbackowl-loader: add a debug message when swapping the eeprom dataowl-loader: add missing newlines in log messagesReviewed-by: Julian Calaby Signed-off-by: Christian Lamparter Signed-off-by: Martin Blumenstingl Signed-off-by: Kalle Valo List of files: /linux-6.15/drivers/net/wireless/ath/ath9k/Makefile

9df7ddc3 - ath9k: move spectral scan support under a separate config symbol

Mon, 27 Nov 2017 17:56:22 +0000

ath9k: move spectral scan support under a separate config symbolAt the moment, spectral scan support, and with it RELAY, is always enabledwith ATH9K[_HTC]_DEBUGFS. Spectral scan support is currently the only userof RELAY in ath9k, and it unconditionally reserves a relay channel.Having debugfs support in ath9k is often useful even on very small embeddedrouters, where we'd rather like to avoid the code size and RAM usage of therelay support.Signed-off-by: Matthias Schiffer Signed-off-by: Kalle Valo List of files: /linux-6.15/drivers/net/wireless/ath/ath9k/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/net/wireless/ath/ath9k/Makefile

1077ec47 - ath9k: move RELAY and DEBUG_FS to ATH9K[_HTC]_DEBUGFS

Thu, 12 Jan 2017 11:02:23 +0000

ath9k: move RELAY and DEBUG_FS to ATH9K[_HTC]_DEBUGFSCurrently, the common ath9k_common module needs to have adependency on RELAY and DEBUG_FS in order to built. Thisis usually not a problem. But for RAM and FLASH starvedAR71XX devices, every little bit counts.This patch adds a new symbol CONFIG_ATH9K_COMMON_DEBUGwhich makes it possible to drop the RELAY and DEBUG_FSdependency there and move it to ATH_(HTC)_DEBUGFS.Note: The shared FFT/spectral code (which is the only userof the relayfs in ath9k*) needs DEBUG_FS to export the relayfsinterface to dump the data to userspace. So it makes no senseto have the functions compiled in, if DEBUG_FS is not there.Signed-off-by: Christian Lamparter Signed-off-by: Kalle Valo List of files: /linux-6.15/drivers/net/wireless/ath/ath9k/Makefile

ed14dc0a - ath9k: feeding entropy in kernel from ADC capture

Fri, 09 Oct 2015 09:06:45 +0000

ath9k: feeding entropy in kernel from ADC captureThis patch is derived fromcommit 6301566e0b2d ("ath9k: export HW random number generator"),We evaluated the entropy of the ADC data on QCA9531, QCA9561, QCA955x,and AR9340, and it has sufficient quality random data (at least 10 bitsand up to 22 bits of min-entropy for a 32-bit value). We conservativelyassume the min-entropy is 10 bits out of 32 bits. Thus, ATH9K_RNG_BUF_SIZEis set to 320 (u32) i.e., 1.25 kilobytes of data is inserted to fill upthe pool as soon as the entropy counter becomes 896/4096 (set by random.c).Since ADC was not designed to be a dedicated HW RNG, we do not want to bindit to /dev/hwrng framework directly. This patch feeds the entropy directlyfrom the WiFi driver to the input pool. The ADC register output is onlyused as a seed for the Linux entropy pool. No conditioning is needed,since all the conditioning is performed by the pool itself.Signed-off-by: Miaoqing Pan Signed-off-by: Kalle Valo List of files: /linux-6.15/drivers/net/wireless/ath/ath9k/Makefile

9e495a26 - ath9k: Remove ath9k rate control

Thu, 06 Feb 2014 04:52:55 +0000

ath9k: Remove ath9k rate controlThere is no benefit in retaining the legacy rate control modulein the driver codebase.It is known to be buggy and has less than optimal performancein real-world environments compared with minstrel. The onlyreason that it was kept when we made the switch to minstrelas default was that it showed higher throughput numbers in aclean/ideal environment.This is no longer the case and minstrel can push ath9k tothe same throughput levels. In TCP, with 3-stream cards, more than295 Mbps can be obtained in open air, with 2-stream cards,210 Mbps is easily reached. To test performance issues,instead of using a broken rate control module, it is betterto use the fixed-rate interface provided by mac80211 anyway.The ath9k RC has not received any bug fixes in years and isjust bit-rotting away - this patch removes it.Signed-off-by: Sujith Manoharan Signed-off-by: John W.
