Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license 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 binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the 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 cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base 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 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately 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 license
identifiers 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 the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version 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 correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

We are missing building windfarm_max6690_sensor.o when building
CONFIG_WINDFARM_RM31. Usually all the windfarm drivers are built
and thus this isn't a problem but some more "tailored" setups
(Gentoo ?) building only that driver are not working because
the require sensor module is missing.

This replaces the old therm_pm72 using the same windfarm infrastructure
that was used for other PowerMac G5 models. The fan speeds and sensors
should now be visible in the same location in sysfs.
The driver is split into separate core modules for PowerMac7,2 (and 7,3)
and RackMac3,1, with a lot of the shared code now in the separate sensor
and control modules.

The ams driver isn't a hardware monitoring driver, so it shouldn't

This patch contains a total rewrite of the backlight infrastructure for
portable Apple computers. Backward compatibility is retained. A sysfs
interface allows userland to control the brightness with more steps than
before. Userland is allowed to upload a brightness curve for different
monitors, similar to Mac OS X.

This patch adds a windfarm module, windfarm_pm112, for the dual core G5s
(both 2 and 4 core models), keeping the machine from getting into
vacuum-cleaner mode ;) For proper credits, the patch was initially
written by Paul Mackerras, and slightly reworked by me to add overtemp
handling among others. The patch also removes the sysfs attributes from
windfarm_pm81 and windfarm_pm91 and instead adds code to the windfarm
core to automagically expose attributes for sensor & controls.

This adds sysfs nodes that the hotplug userspace can use to load the
appropriate modules.
In order for hotplug to work with macio devices, patches to
module-init-tools and hotplug must be applied. Those patches are
available at:
ftp://ftp.suse.com/pub/people/jeffm/linux/macio-hotplug/
Changes: The previous versions were built on 2.6.12. 2.6.13-rcX introduced
a device_attribute parameter to the show functions. Since that
parameter was treated as the output buffer, memory corruption would
result, causing Oopsen very quickly.

The iMac G5 and latest single-cpu PowerMac G5 have seen the venerable PMU
(Power Management Unit) chip been sent to well deserved retirement. It has
been replaced by a newcomer, the SMU (System Management Unit ?) which is of
course totally undocumented and has no open source darwin driver... The
SMU chip is responsible of initializing the chipset & CPU (boot process),
power supply control, real time clock, fan control, provides some i2c
busses, etc... etc... etc...
This is a very basic driver based on the Open Firmware methods for
accessing this chip. It provides synchronous functions only, and does
restart, shutdown, and real time clock access. There is still no fan
control, at least not until we have figured out how to access the fans via
the SMU.
The initial code was written by J. Mayer <l_indien@magic.fr>, I mostly
rewrote it to better adhere to our coding style standards ;)
The patch also updates the g5_defconfig to include the SMU support by
default.

From: "Colin Leroy" <colin@colino.net>
The fan driver I wrote for adt746x looks like it only handles the adt7467
chip found in iBooks G4; but it also handles the adt7460 chip found in the
Powerbook G4 Alu. Here's a patch that updates therm_adt7467.c, Kconfig and
Makefile.
|
|
Adds thermal management drivers for desktop G5, Windtunnel G4s, and
recent laptops (iBook G4, aluminium 15" and 17" powerbooks)
|
|
move drivers/macintosh/nvram.c to drivers/char/generic_nvram.c,
update platform hooks,
fix powermac nvram driver for newer machines
|
|
This provides the necessary infrastructure for PowerMac specific drivers
(and actually some Open Firmware platform drivers on non-PowerMacs as
well provided somebody port them) to be properly probed & referenced via
the new driver model and be part of sysfs.
As-is, this patch doesn't break anything nor change any driver. I'll
send you individual driver patches as I clean them up & get them tested
on as many machines as possible, though I don't expect much problems.
|
|
One of the goals of the whole new modversions implementation:
export-objs is gone for good!
|
|
Makefiles no longer need to include Rules.make, which is currently an
empty file. This patch removes it from the drivers tree Makefiles.
|
|
This removes two drivers from drivers/macintosh. The files affected are
all in drivers/macintosh. First, the patch removes the old macintosh
ADB keyboard driver and the macintosh keymap file, which are no longer
used now that we use the input layer and the adbhid.c driver. Secondly,
it removes the drivers/macintosh/rtc.c driver, which was only ever used
on PPC, and which is obsolete now that we use the drivers/char/genrtc.c
driver instead.
|
|
I noticed you just pushed the pc_keyb.c removal to linux-input, here is the
PPC part of it that removes now superflous stuff. The small change in
keyboard.c is a bugfix from 2.4 and ruby that didn't make it into 2.5 yet.

This patch cleans up most of the Makefile's to list the correct files
(i.e. the ones which do have "EXPORT_SYMBOL" in them) in $(export-objs)

We currently decide whether we need to descend into the subdirs of
drivers/ in drivers/Makefile, but link the resulting objects from
the top-level Makefile.
Making these two decisions at the same time (in drivers/Makefile) cleans
up the top-level Makefile quite a bit.
Link order does not change at all apart from sound/, which is now linked
