DRM is a lot more than a direct rendering manager nowadays, and there's
also a bunch of things worth documenting for gpu driver developers
outside of drivers/gpu/drm, like vgaarb, vga_switcheroo or the various
hardware buses like host1x and ipu-v3.
To avoid further confusion let's rename the top-level to reflect
reality.
And yes I'm already looking forward to when we need to replace the G
in GPU with a * ;-)
Inspired by a thread with Lukas since he refused to include the
vga_switcheroo docs into the drm docs because it's not drm.

With the prep patches for i915 all kms drivers either have
DRM_UNLOCKED on all their ioctls. Or the ioctl always directly returns
with an invariant return value when in modeset mode. But that's only
the case for i915 and radeon. The drm core ioctls are unfortunately
too much a mess still to dare this.
Follow-up patches will remove DRM_UNLOCKED from all kms drivers to
prove that this is indeed the case.
Also update the documentation.
v2: Really only do this for driver ioctls, spotted by David Herrmann.
And drop spurious whitespace change.

drm/doc: Update docs about device instance setup
For location and connectivity services, userspace would often like
to know the time when the BSS was last seen. The current "last seen"
value is calculated in a way that makes it less useful, especially
if the system suspended in the meantime.
Add the ability for the driver to report a real CLOCK_BOOTTIME stamp
that can then be reported to userspace (if present).
Drivers wishing to use this must be converted to the new API to call
cfg80211_inform_bss_data() or cfg80211_inform_bss_frame_data(). They
need to ensure the reported value is accurate enough even when the
frame might have been buffered in the device (e.g. firmware.)

This enum is not actually used anymore. The only value used from

The DocBook/media/dvb/kdapi.xml contains the description of
the kABI for DVB. The problem is that, by being maintained
on a separate file and not being updated for years, it got
outdated. So, for example, some callback parameters were
changed, but the DocBook were still using the old stuff.
As a first step to fix it, let's move the documentation of
struct dmx_demux into demux.h and fix the parameters used
there.
For now, don't document any other field nor touch the
descriptions that got moved, letting this job to other
patches. That makes easier to review the patch.
PS.: Please notice that an additional patch will be needed
in order to fix the return values (some uses non-existent
return codes) and to the functions and callbacks mentioned at
the descriptions.

->load is deprecated, bus functions are deprecated and everyone
should use drm_dev_alloc®ister.
So update the .tmpl (and pull a bunch of the overview docs into the
sourcecode to increase chances that it'll stay in sync in the future)
and add notes to functions which are deprecated. I didn't bother to
clean up and document the unload sequence similarly since that one is
still a bit a mess: drm_dev_unregister does way too much,
drm_unplug_dev does what _unregister should be doing but then has the
complication of promising something it doesn't actually do (it doesn't
unplug existing open fds for instance, only prevents new ones).
Motivated since I don't want to hunt every new driver for usage of
drm_platform_init any more ;-)
v2: Reword the deprecation note for ->load a bit, using Laurent's
suggestion as an example (but making the wording a bit stronger even).
Fix spelling in commit message.

There are little changes in core part, but lots of development are
found in drivers, especially ASoC. The diffstat shows regmap-
related changes for a slight API additions / changes, and that's all.
Looking at the code size statistics, the most significant addition
is for Intel Skylake. (Note that SKL support is still underway, the
codec driver is missing.) Also STI controller driver is a major
addition as well as a few new codec drivers.
In HD-audio side, there are fewer changes than the past. The
noticeable change is the support of ELD notification from i915
graphics driver. Thus this pull request carries a few changes in
drm/i915.
Other than that, USB-audio got a rewrite of runtime PM code. It
was initiated by lockdep warning, but resulted in a good cleanup in
the end.
Below are the highlights:
Common:
- Factoring out of AC'97 reset code from ASoC into the core helper
- A few regmap API extensions (in case it's not pulled yet)
ASoC:
- New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek
RT298 and ST STI controllers
- Machine drivers for Rockchip systems with MAX98090 and RT5645 and
RT5650
- Initial driver support for Intel Skylake devices
- Lots of rsnd cleanup and enhancements
- A few DAPM fixes and cleanups
- A large number of cleanups in various drivers (conversion and
standardized to regmap, component) mostly by Lars-Peter and Axel
HD-audio:
- Extended HD-audio core for Intel Skylake controller support
- Quirks for Dell headsets, Alienware 15
- Clean up of pin-based quirk tables for Realtek codecs
- ELD notifier implenetation for Intel HDMI/DP
USB-audio:
- Refactor runtime PM code to make lockdep happier

Pull ext3 removal, quota & udf fixes from Jan Kara:
"The biggest change in the pull is the removal of ext3 filesystem
driver (~28k lines removed). Ext4 driver is a full featured
replacement these days and both RH and SUSE use it for several years
without issues. Also there are some workarounds in VM & block layer
mainly for ext3 which we could eventually get rid of.
Other larger change is addition of proper error handling for
dquot_initialize(). The rest is small fixes and cleanups"

falling through the cracks for legacy users, but ext4 maintainers
piped up and were all unanimously in favor of removal, and maintaining

Two notes here:
1) As videobuf2-core will be soon be changed, better to
not spend too much efforts right now, as things will
change soon;
2) struct vb2_queue has a number of private elements that are
documented. As Kernel nano documentation format handles

obviously better ;)

Functions, Structs and Parameters definitions on kernel documentation
are pure cosmetic, it only highlights the element.
To ease the navigation in the documentation we should use <links> inside
those tags so readers can easily jump between methods directly.
This was discussed in 2014[1] and is implemented by getting a list
of <refentries> from the DocBook XML to generate a database. Then it looks
for <function>,<structnames> and <paramdef> tags that matches the ones in
the database. As it only links existent references, no broken links are
added.

For generic IIO trigger implementations we already have a sub-directory,
but the generic buffer implementations currently reside in the IIO
top-level directory. The main reason is that things have historically grown
into this form.
With more generic buffer implementations on its way now is the perfect time
to clean this up and introduce a sub-directory for generic buffer
implementations to avoid too much clutter in the top-level directory.

Some kernel-doc sections are included in multiple DocBook files. This
means the mandocs target will generate the same manual page multiple
times with different metadata (author name/address and manual title,
taken from the including DocBook file). If it's invoked in a parallel
build, the output is non-determinstic.
Build the manual pages in a separate subdirectory per DocBook file,
then sort and de-duplicate when installing them (which is serialised).

GuC-based submission is mostly the same as execlist mode, up to
intel_logical_ring_advance_and_submit(), where the context being
dispatched would be added to the execlist queue; at this point
we submit the context to the GuC backend instead.
There are, however, a few other changes also required, notably:
1. Contexts must be pinned at GGTT addresses accessible by the GuC
i.e. NOT in the range [0..WOPCM_SIZE), so we have to add the
PIN_OFFSET_BIAS flag to the relevant GGTT-pinning calls.
2. The GuC's TLB must be invalidated after a context is pinned at
a new GGTT address.
3. GuC firmware uses the one page before Ring Context as shared data.
Therefore, whenever driver wants to get base address of LRC, we
will offset one page for it. LRC_PPHWSP_PN is defined as the page
number of LRCA.
4. In the work queue used to pass requests to the GuC, the GuC
firmware requires the ring-tail-offset to be represented as an
11-bit value, expressed in QWords. Therefore, the ringbuffer
size must be reduced to the representable range (4 pages).
v2:
Defer adding #defines until needed [Chris Wilson]
Rationalise type declarations [Chris Wilson]
v4:
Squashed kerneldoc patch into here [Daniel Vetter]
v5:
Update request->tail in code common to both GuC and execlist modes.
Add a private version of lr_context_update(), as sharing the
execlist version leads to race conditions when the CPU and
the GuC both update TAIL in the context image.
Conversion of error-captured HWS page to string must account
for offset from start of object to actual HWS (LRC_PPHWSP_PN).

Take 2 also includes a fix set that was too late for the 4.2 cycle.
As we had a lot of tools and docs work in this set, I have broken those
out into their own categories in this description.
Fixes from the pull request '4th set of IIO fixes for the 4.2 cycle'.
* Poll functions for both event chardev and the buffer one were returning
negative error codes (via a positive value).
* A recent change to lsiio adding some error handling that was wrong and
stopped the tool working.
* bmg160 was missing some dependencies in Kconfig
* berlin2-adc had a misshandled register (wrote a value rather than a bitmap)
New device support
* TI opt3001 light sensor
* TXC PA12 ALS and proximity sensor.
* mcp3301 ADC support (in mcp320x driver)
* ST lsm303agr accelerometer and magnetometer drivers (plus some st-sensors
common support to allow different WHOAMI register addresses, devices with
fixed scale and allow interrupt equiped magnetometers).
* ADIS16305, ADIS16367, ADIS16445IMUs (in the adis16400 driver)
* ADIS16266 gyro (in the adis16260 driver)
* ADIS16137 gyro (in the adis16136 driver)
New functionality
* mmc35240 DT bindings.
* Inverse unit conversion macros to aid handing of values written to sysfs
attributes.
Core cleanup
* Forward declaration of struct iio_trigger to avoid a compile warning.
Driver cleanup / fixes
* mxs-lradc
- Clarify which parts are supported.
- Fix spelling erorrs.
- Missing/extra includes
- reorder includes
- add datasheet name listings for all usable channels (to allow them
to be bound by name from consumer drivers)
* acpi-als - add some function prefixes as per general iio style.
* bmc150_magn - replace a magic value with the existing define.
* vf610 - determine possible sample frequencies taking into account the
electrical characteristics (defining a minimum sample time)
* dht11
- whitespace
- additional docs
- avoid mulitple assignments in one line
- Use the new funciton ktime_get_resolution_ns to cleanup a nasty trick
previously used for timing.
* Fix all drivers that consider 0 a valid IRQ for historical reasons.
* Export I2C module alias info where previously missing (to allow autoprobing)
* Export OF module alias info where previously missing.
* mmc35240 - switch some variables into arrays to improve readability.
* mlx90614 - define some magic numbers for readability.
* bmc150_magn
- expand area locked by a mutex to cover all the use of the
data->buffer.
- use descriptive naming for a mask instead of a magic value.
* berin2-adc
- pass up an error code rather that a generic error
- constify the iio_chan_spec
- some other little tidy ups.
* stk8312
- fix a dependency on triggered buffers in kconfig
- add a check for invalid attribute values
- improve error handling by returning error codes where possible and
return immediately where relevant
- rework macro defs to use GENMASK etc
- change some variable types to reduce unnecessary casting
- clean up code style
- drop a local buffer copy for bulk reads and use the one in data->buffer
instead.
* adis16400 - the adis16448 gyroscope scale was wrong.
* adis16480 - some more wrong scales for various parts.
* adis16300 - has an undocumented product id and serial number registers so
use them.
* iio_simple_dummy - fix some wrong code indentation.
* bmc150-accel - use the chip ID to detect the chip present rather than
verifying the expected part was there. This was in response to a wrong
ACPI entry on the WinBook TW100.
* mma8452
- fix _get_hp_filter_index
- drop a double include
- pass up an error code rather than rewriting it
- range check input values to attribute writes
- register defs tidy up using GENMASK and reordering them to be easier to
follow.
- various coding style cleanups
- put the Kconfig entry in the write place (alphabetically).
Tools related
* Tools cleanup - drop an explicity NULL comparison, some unnecessary braces,
use the ARRAY_SIZE macro, send error messages to stderr instead of dropping
them in the middle of normal output.
* Fix tools to allow that scale and offset attributes are optional.
* More tools fixes including allowing true 32bit data (previously an overflow
prevented more than 31bits)
* Drop a stray header guard that ended up in a c file.
* Make calc_digits static as it isn't exported or in the header.
* Set ci_array pointer to NULL after free as a protection against non safe
usage of the tools core code. Also convert a double pointer to a single
one as the extra level of indirection was unnecessary.
Docs
* DocBook introduction by Daniel Baluta. Glad we are beginning to
draw together some more introductory docs to suplement the various
tools / examples.
* Drop bytes_per_datum sysfs attribute docs as it no longer exists.
* A whole load of missing / fixing of kernel-doc for the core of IIO.
* Document the trigger name sysfs attribute in the ABI docs.
* Minor typos in the ABI docs related to power down modes.

Chris rightfully suggested that documenting fences without documenting
the BO tiling tracking doesn't make much sense, so fix that.
The important bit to stress here (since it lead to some confusion) is
the GEM doesn't really care about tiling. Except for a few select cases
where the kernel needs to manage something that userspace can't take
care of: Namely the limited number of fences and fixing up swizzling,
although we still fail at the later.
v2: Move the low-level tiling/swizzling functions and kerneldoc to
i915_gem_fence.c and leave only the userspace interface here.

Some kernel-doc sections are included in multiple DocBook files. This
means the mandocs target will generate the same manual page multiple
times with different metadata (author name/address and manual title,
taken from the including DocBook file). If it's invoked in a parallel
build, the output is nondeterminstic.
For each section that is duplicated, mark the less specific manual's
inclusion as 'extra' and exclude it during conversion to manual pages.
Use xmlif for this, as that is bundled with xmlto which we already
use.
I would have preferred to use more conventional markup for this, but
each of the following approaches failed:
1. Wrap the extra inclusions with a new element and add a template to
the stylesheet to include/exclude them. Unfortunately DocBook XSL
doesn't seem to support foreign elements at an intermediate level
in the document tree.
2. Use DocBook profiling. This works but requires passing an absolute
path to the profile stylesheet to xmlto, so it's not portable.
3. Use SGML marked sections. docbook2x can handle these but xmlto
chokes on them.

The mtime on a man page is the build time. As gzip stores the mtime

Pull drm updates from Dave Airlie:
"This is the main drm pull request for v4.2.
I've one other new driver from freescale on my radar, it's been posted
and reviewed, I'd just like to get someone to give it a last look, so
maybe I'll send it or maybe I'll leave it.
There is no major nouveau changes in here, Ben was working on
something big, and we agreed it was a bit late, there wasn't anything
else he considered urgent to merge.
There might be another msm pull for some bits that are waiting on
arm-soc, I'll see how we time it.
This touches some "of" stuff, acks are in place except for the fixes
to the build in various configs,t hat I just applied.
Summary:
New drivers:
- virtio-gpu:
KMS only pieces of driver for virtio-gpu in qemu.
This is just the first part of this driver, enough to run
unaccelerated userspace on. As qemu merges more we'll start
adding the 3D features for the virgl 3d work.
- amdgpu:
a new driver from AMD to driver their newer GPUs. (VI+)
It contains a new cleaner userspace API, and is a clean
break from radeon moving forward, that AMD are going to
concentrate on. It also contains a set of register headers
auto generated from AMD internal database.
core:
- atomic modesetting API completed, enabled by default now.
- Add support for mode_id blob to atomic ioctl to complete interface.
- bunch of Displayport MST fixes
- lots of misc fixes.
panel:
- new simple panels
- fix some long-standing build issues with bridge drivers
radeon:
- VCE1 support
- add a GPU reset counter for userspace
- lots of fixes.
amdkfd:
- H/W debugger support module
- static user-mode queues
- support killing all the waves when a process terminates
- use standard DECLARE_BITMAP
i915:
- Add Broxton support
- S3, rotation support for Skylake
- RPS booting tuning
- CPT modeset sequence fixes
- ns2501 dither support
- enable cmd parser on haswell
- cdclk handling fixes
- gen8 dynamic pte allocation
- lots of atomic conversion work
exynos:
- Add atomic modesetting support
- Add iommu support
- Consolidate drm driver initialization
- and MIC, DECON and MIPI-DSI support for exynos5433
omapdrm:
- atomic modesetting support (fixes lots of things in rewrite)
tegra:
- DP aux transaction fixes
- iommu support fix
msm:
- adreno a306 support
- various dsi bits
- various 64-bit fixes
- NV12MT support
rcar-du:
- atomic and misc fixes
sti:
- fix HDMI timing complaince
tilcdc:
- use drm component API to access tda998x driver
- fix module unloading
qxl:
- stability fixes"

Pull media updates from Mauro Carvalho Chehab:
- Lots of improvements at the DVB API DocBook documentation. Now, the
frontend and the network APIs are fully in sync with the Kernel and
looks more like the rest of the media documentation;
- New frontend driver: cx24120
- New driver for a PCI device: cobalt. This driver is actually not
sold in the market, but it is a good example of a multi-HDMI input
device;
- The dt3155 driver were promoted from staging;
- The mantis driver got remote controller support;
- New V4L2 driver for ST bdisp SoC chipsets;
- Make sparse and smatch happier: several bugs were solved by fixing
the issues reported by those static code analyzers.
- Lots of new device additions, new features, improvements and cleanups
at the existing drivers.

Current documentation over use case for EXPORT_SYMBOL_GPL()
only acknowledges functions which are "an internal implementation
issue, and not really an interface". In practice these days
though we have some maintainers taking on preferences to require
all new functionality go in with EXPORT_SYMBOL_GPL().
A maintainer asking developers to use EXPORT_SYMBOL_GPL()
for new functionality tends to be a well accepted and understood
position that maintainers can take and typically requires the
maintainers educating contributing developers on their own
positions and requirements.
Developers who submit code to maintainers not familiar with
these preferences as optional for new functionality need explicit
guidence though as existing documentation does not acknowledge
this as a valid possibility. Without this being documented some
maintainers are reluctant to accept new functionality with
EXPORT_SYMBOL_GPL().
This extends the use case documentation for EXPORT_SYMBOL_GPL()
to acknowledge acceptance for new functionality.

One more round of drm-misc, again mostly atomic. Big thing is the
userspace blob code from Daniel Stone, with support for the mode_id blob
now added to the atomic ioctl. Finally we can do atomic modesets!
Note that the atomic ioctl is still behind the module knob since the
weston patches aren't quite ready yet imo - they lack TEST_ONLY support,
which is a fairly crucial bit of the atomic api. But besides that I think
it's all good to go. That's also why we didn't bother to hide the new blob
ioctls behind the knob, that part won't need to change. And if weston
patches get in shape in time we could throw the "atomic by default patch"
on top for 4.2.

What's written there about the arguments for this ioctl
is bogus: it doesn't return an enum (or a typedef)
for enum fe_status. Instead, it returns a bitmask with the
values defined by enum fe_status.
Also, the size of the integer returned is not 16 bits, but,
instead, sizeof(fe_status_t), e. g. sizeof(enum), with is
arch-dependent.
This should of course be fixed, but this should be done on
a separate patch.

Move the function ioctl definitions to the end of the chapter,
at their importance. That makes the document better organized,
as the DVB frontend system call index will look like:
open()
close()
ioctl FE_GET_INFO — Query DVB frontend capabilities and returns information about the front-end. This call only requires read-only access to the device
ioctl FE_READ_STATUS — Returns status information about the front-end. This call only requires read-only access to the device
ioctl FE_SET_PROPERTY, FE_GET_PROPERTY — FE_SET_PROPERTY sets one or more frontend properties. FE_GET_PROPERTY returns one or more frontend properties.
ioctl FE_DISEQC_RESET_OVERLOAD — Restores the power to the antenna subsystem, if it was powered off due to power overload.
ioctl FE_DISEQC_SEND_MASTER_CMD — Sends a DiSEqC command
ioctl FE_DISEQC_RECV_SLAVE_REPLY — Receives reply from a DiSEqC 2.0 command
ioctl FE_DISEQC_SEND_BURST — Sends a 22KHz tone burst for 2x1 mini DiSEqC satellite selection.
ioctl FE_SET_TONE — Sets/resets the generation of the continuous 22kHz tone.
ioctl FE_SET_VOLTAGE — Allow setting the DC level sent to the antenna subsystem.
ioctl FE_ENABLE_HIGH_LNB_VOLTAGE — Select output DC level between normal LNBf voltages or higher LNBf voltages.
ioctl FE_SET_FRONTEND_TUNE_MODE — Allow setting tuner mode flags to the frontend.
