Thu, 02 May 2019 13:42:31 +0000

media: move drivers/media/media-* to drivers/media/mc/mc-*It is really weird that the media controller sources are all top-levelin drivers/media. It is a bit of a left-over from long ago when mostmedia sources were all at the top-level. At some point we reorganizedthe directory structure, but the media-*.c sources where never movedto their own directory.So create a new mc directory and move all sources there. Also renamethe prefix from media- to mc-.Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/Makefile

6e1d824e - media: Media Device Allocator API

Tue, 02 Apr 2019 00:40:19 +0000

media: Media Device Allocator APIMedia Device Allocator API to allows multiple drivers share a media device.This API solves a very common use-case for media devices where one physicaldevice (an USB stick) provides both audio and video. When such media deviceexposes a standard USB Audio class, a proprietary Video class, two or moreindependent drivers will share a single physical USB bridge. In such cases,it is necessary to coordinate access to the shared resource.Using this API, drivers can allocate a media device with the shared structdevice as the key. Once the media device is allocated by a driver, otherdrivers can get a reference to it. The media device is released when allthe references are released.Signed-off-by: Shuah Khan Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/Makefile

10905d70 - media: media-request: implement media requests

Mon, 21 May 2018 08:54:27 +0000

media: media-request: implement media requestsAdd initial media request support:1) Add MEDIA_IOC_REQUEST_ALLOC ioctl support to media-device.c2) Add struct media_request to store request objects.3) Add struct media_request_object to represent a request object.4) Add MEDIA_REQUEST_IOC_QUEUE/REINIT ioctl support.Basic lifecycle: the application allocates a request, addsobjects to it, queues the request, polls until it is completedand can then read the final values of the objects at the timeof completion. When it closes the file descriptor the requestmemory will be freed (actually, when the last user of that requestreleases the request).Drivers will bind an object to a request (the 'adds objects to it'phase), when MEDIA_REQUEST_IOC_QUEUE is called the request isvalidated (req_validate op), then queued (the req_queue op).When done with an object it can either be unbound from the request(e.g. when the driver has finished with a vb2 buffer) or marked ascompleted (e.g. for controls associated with a buffer). When allobjects in the request are completed (or unbound), then the requestfd will signal an exception (poll).Co-developed-by: Sakari Ailus Co-developed-by: Laurent Pinchart Co-developed-by: Alexandre Courbot Signed-off-by: Hans Verkuil Signed-off-by: Sakari Ailus Reviewed-by: Mauro Carvalho Chehab Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/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/media/Makefile

Mon, 17 Apr 2017 10:44:35 +0000

[media] cec: Kconfig cleanupThe Kconfig options for the CEC subsystem were a bit messy. Inaddition there were two cec sources (cec-edid.c and cec-notifier.c)that were outside of the media/cec directory, which was weird.Move those sources to media/cec as well.The cec-edid and cec-notifier functionality is now part of the cecmodule and these are no longer separate modules.Also remove the MEDIA_CEC_EDID config option and include it with themain CEC config option (which defined CEC_EDID anyway).Added static inlines to cec-edid.h for dummy functions when CEC_COREisn't defined.CEC drivers should now depend on CEC_CORE.CEC drivers that need the cec-notifier functionality must explicitlyselect CEC_NOTIFIER.The s5p-cec and stih-cec drivers depended on VIDEO_DEV instead ofCEC_CORE, fix that as well.Signed-off-by: Hans Verkuil Acked-by: Benjamin Gaignard Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/Makefile

[media] bq/c-qcam, w9966, pms: move to staging in preparation for removalThese drivers haven't been tested in a long, long time. The hardware isancient and hopelessly obsolete. These drivers also need to be convertedto newer media frameworks but due to the lack of hardware that's goingto be impossible. In addition, cheaper and vastly better hardware isavailable today.So these drivers are a prime candidate for removal.

While there are macros that allow changingthe init order, like subsys_initcall(), late_initcall() & friends,when all drivers linked belong to the same subsystem, it is easierto change the order at the Makefile.All I2C modules must be linked before any drivers that actually use it,in order to ensure proper module initialization order.Also, the core drivers should be initialized before the drivers that usethem.This patch reorders the drivers init, in order to fulfill the aboverequirements.Reported-by: Sylwester Nawrocki Acked-by: Sylwester Nawrocki Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/Makefile
