kernel-doc-rst-lint: add tool to check kernel-doc and rst correctness
Simple kernel-doc and reStructuredText lint tool that can be used
independently and as a kernel build CHECK tool to validate kernel-doc
comments.
Independent usage:
$ kernel-doc-rst-lint FILE
Kernel CHECK usage:
$ make CHECK=scripts/kernel-doc-rst-lint C=1 # (or C=2)
Depends on docutils and the rst-lint package

doc/sphinx: Track line-number of starting blocks
Design is pretty simple: kernel-doc inserts breadcrumbs with line
numbers, and sphinx picks them up. At first I went with a sphinx
comment, but inserting those at random places seriously upsets the
parser, and must be filtered. Hence why this version now uses "#define
LINEO " since one of these ever escape into output it's pretty clear
there is a bug.
It seems to work well, and at least the 2-3 errors where sphinx
complained about something that was not correct in kernel-doc text the
line numbers matched up perfectly.
v2: Instead of noodling around in the parser state machine, create
a ViewList and parse it ourselves. This seems to be the recommended
way, per Jani's suggestion.
v3:
- Split out ViewList pach. Splitting the kernel-doc changes from the
sphinx ones isn't possible, since emitting the LINENO lines wreaks
havoc with the rst formatting. We must filter them.
- Improve the regex per Jani's suggestions, and compile it just once
for speed.
- Now that LINENO lines are eaten, also add them to function parameter
descriptions. Much less content and offset than for in-line struct
member descriptions, but still nice to know which exact continuation
line upsets sphinx.
- Simplify/clarify the line +/-1 business a bit.
v4: Split out the scripts/kernel-doc changes and make line-numbers
opt-in, as suggested by Jani.

scripts/kernel-doc: Add option to inject line numbers
Opt-in since this wreaks the rst output and must be removed
by consumers again. This is useful to adjust the linenumbers
for included kernel-doc snippets in shinx. With that sphinx
error message will be accurate when there's issues with the
rst-ness of the kernel-doc comments.
Especially when transitioning a new docbook .tmpl to .rst this
is extremely useful, since you can just use your editors compilation
quickfix list to accurately jump from error to error.
v2:
- Also make sure that we filter the LINENO for purpose/at declaration
start so it only shows for selected blocks, not all of them (Jani).
While at it make it a notch more accurate.
- Avoid undefined $lineno issues. I tried filtering these out at the
callsite, but Jani spotted more when linting the entire kernel.
Unamed unions and similar things aren't stored consistently and end
up with an undefined line number (but also no kernel-doc text, just
the parameter type). Simplify things and filter undefined line
numbers in print_lineno() to catch them all.
v3: Fix LINENO 0 issue for kernel-doc comments without @param: lines
or any other special sections that directly jump to the description
after the "name - purpose" line. Only really possible for functions
without parameters. Noticed by Jani.

scripts/kernel-doc: Remove duplicated DOC: start handling
Further up in the state machinery we switch from STATE_NAME to
STATE_DOCBLOCK when we match /$doc_block/. Which means this block of
code here is entirely unreachable, unless there are multiple DOC:
sections within a single kernel-doc comment.
Getting a list of all the files with more than one DOC: section using
$ git grep -c " * DOC:" | grep -v ":1$"
and then doing a full audit of them reveals there are no such comment
blocks in the kernel.
Supporting multiple DOC: sections in a single kernel-doc comment does
not seem like a recommended way of doing things anyway, so nuke the code

drm: Store the plane's index
Currently the plane's index is determined by walking the list of all
planes in the mode and finding the position of that plane in the list. A
linear walk, especially a linear walk within a linear walk as frequently
conceived by i915.ko [O(N^2)] quickly comes to dominate profiles.
The plane's index is constant for as long as no earlier planes are
removed from the list. For all drivers, planes are static, determined
at boot and then untouched until shutdown. In fact, there is no locking
provided to allow for dynamic removal of planes/encoders/crtcs.
v2: Convert drm_crtc_index() and drm_encoder_index() as well.
v3: Stop adjusting the indices upon removal; consider the list
construct-only.

Currently the plane's index is determined by walking the list of all
planes in the mode and finding the position of that plane in the list. A
linear walk, especially a linear walk within a linear walk as frequently
conceived by i915.ko [O(N^2)] quickly comes to dominate profiles.
The plane's index is constant for as long as no earlier planes are
removed from the list. For all drivers, planes are static, determined
at boot and then untouched until shutdown. In fact, there is no locking
provided to allow for dynamic removal of planes/encoders/crtcs.
v2: Convert drm_crtc_index() and drm_encoder_index() as well.
v3: Stop adjusting the indices upon removal; consider the list
construct-only.

drm/fence: add fence to drm_pending_event
Now a drm_pending_event can either send a real drm_event or signal a
fence, or both. It allow us to signal via fences when the buffer is
displayed on the screen. Which in turn means that the previous buffer
is not in use anymore and can be freed or sent back to another driver
for processing.
v2: Comments from Daniel Vetter
- call fence_signal in drm_send_event_locked()
- remove unneeded !e->event check
v3: Remove drm_pending_event->destroy to fix a leak when e->file_priv
is not set.

drm: hdlcd: Cleanup the atomic plane operations
Harden the plane_check() code to drop attempts at scaling because
that is not supported. Make hdlcd_plane_atomic_update() set the pitch

And make hdlcd_crtc_mode_set_nofb() a helper function for
hdlcd_crtc_enable() rather than an exposed hook.

drm: hdlcd: Revamp runtime power management
Because the HDLCD driver acts as a component master it can end
up enabling the runtime PM functionality before the encoders
are initialised. This can cause crashes if the component slave
never probes (missing module) or if the PM operations kick in
before the probe finishes.
Move the enabling of the runtime PM after the component master
has finished collecting the slave components and use the DRM
atomic helpers to suspend and resume the device.

drm/doc: Appease sphinx
Mostly this is unexpected indents. But really it's just a
demonstration for my patch, all these issues have been found&fixed
using the correct source file and line number support I just added.
All line numbers have been perfectly accurate.
One issue looked a bit fishy in intel_lrc.c, where I don't quite grok
what sphinx is unhappy about. But since that file looks like it has
never seen a proper kernel-doc parser I figured better to fix in a
separate path.

drm: Only create a cmdline mode if no probed modes match
The intention of using video=<connector>:<mode> is primarily to select
the user's preferred resolution at startup. Currently we always create a
new mode irrespective of whether the monitor has a native mode at the
desired resolution. This has the issue that we may then select the fake
mode rather the native mode during fb_helper->inital_config() and so
if the fake mode is invalid we then end up with a loss of signal. Oops.
This invalid fake mode would also be exported to userspace, who
potentially may make the same mistake.
To avoid this issue, we filter out the added command line mode if we
detect the desired resolution (and clock if specified) amongst the
probed modes. This fixes the immediate problem of adding a duplicate
mode, but perhaps more generically we should avoid adding a GTF mode if
the monitor has an EDID that is not GTF-compatible, or similarly for
CVT.

drm/i915: Extract physical display dimensions from VBT
The VBT has these mysterious H/V image sizes as part of the display
timings. Looking at some dumps those appear to be the physical
dimensions in mm. Which makes sense since the timing descriptor matches
the format used by EDID detailed timing descriptor, which defines these
as "H/V Addressable Video Image Size in mm".
So let's use that information from the panel fixed mode to get the
physical dimensions for LVDS/eDP/DSI displays. And with that we can
fill out the display_info so that userspace can get at it via
GetConnector.

dma-buf/fence: add fence_array fences v6
struct fence_array inherits from struct fence and carries a
collection of fences that needs to be waited together.
It is useful to translate a sync_file to a fence to remove the complexity
of dealing with sync_files on DRM drivers. So even if there are many
fences in the sync_file that needs to waited for a commit to happen,
they all get added to the fence_collection and passed for DRM use as
a standard struct fence.
That means that no changes needed to any driver besides supporting fences.
To avoid fence_array's fence allocates a new timeline if needed (when
combining fences from different timelines).
v2: Comments by Daniel Vetter:
- merge fence_collection_init() and fence_collection_add()
- only add callbacks at ->enable_signalling()
- remove fence_collection_put()
- check for type on to_fence_collection()
- adjust fence_is_later() and fence_later() to WARN_ON() if they
are used with collection fences.
v3: - Initialize fence_cb.node at fence init.
Comments by Chris Wilson:
- return "unbound" on fence_collection_get_timeline_name()
- don't stop adding callbacks if one fails
- remove redundant !! on fence_collection_enable_signaling()
- remove redundant () on fence_collection_signaled

struct fence_array inherits from struct fence and carries a
collection of fences that needs to be waited together.
It is useful to translate a sync_file to a fence to remove the complexity
of dealing with sync_files on DRM drivers. So even if there are many
fences in the sync_file that needs to waited for a commit to happen,
they all get added to the fence_collection and passed for DRM use as
a standard struct fence.
That means that no changes needed to any driver besides supporting fences.
To avoid fence_array's fence allocates a new timeline if needed (when
combining fences from different timelines).
v2: Comments by Daniel Vetter:
- merge fence_collection_init() and fence_collection_add()
- only add callbacks at ->enable_signalling()
- remove fence_collection_put()
- check for type on to_fence_collection()
- adjust fence_is_later() and fence_later() to WARN_ON() if they
are used with collection fences.
v3: - Initialize fence_cb.node at fence init.
Comments by Chris Wilson:
- return "unbound" on fence_collection_get_timeline_name()
- don't stop adding callbacks if one fails
- remove redundant !! on fence_collection_enable_signaling()
- remove redundant () on fence_collection_signaled
- use fence_default_wait() instead

dma-buf/fence: make fence context 64 bit v2
Fence contexts are created on the fly (for example) by the GPU scheduler used
in the amdgpu driver as a result of an userspace request. Because of this
userspace could in theory force a wrap around of the 32bit context number
if it doesn't behave well.
Avoid this by increasing the context number to 64bits. This way even when
userspace manages to allocate a billion contexts per second it takes more
than 500 years for the context number to wrap around.
v2: fix printf formats as well.

drm: Update obsolete information from {enable/disable}_vblank hooks.
Since commit 4dfd64862ff8 ("drm: Use vblank timestamps to guesstimate
how many vblanks were missed"), the DRM framework can cope with devices
that don't have a hardware counter for vsync events without having
to keep the vsync interrupts enabled all the time. Drivers handling
such hardware should use drm_vblank_no_hw_counter() function for
their ->get_vblank_counter hook.

Since dpi can never be NULL when mtk_dpi_set_display_mode() is called,
remove the message.

doc/sphinx: Pass right filename as source
With this error output becomes almost readable. The line numbers are
still totally bonghits, but that's a lot harder to pull out of
kerneldoc. We'd essentially have to insert some special markers in the
kernel-doc output, split the output along these markers and then
insert each block separately using
state_machine.insert_input(block, source, first_line)

drm/i915: Only ignore eDP ports that are connected
If the VBT says that a certain port should be eDP (and hence fused off
from HDMI), but in reality it isn't, we need to try and acquire the HDMI
connection instead. So only trust the VBT edp setting if we can connect
to an eDP device on that port.

Documentation/sphinx: fix kernel-doc extension on python3
Reconcile differences between python2 and python3 on dealing with
stdout, stderr from Popen. This fixes "name 'unicode' is not defined"
errors on python3. We'll need to try to keep the extension working on
both python-sphinx and python3-sphinx so we don't need two copies.

afee4d8707ab1f21b7668de995be3a5961e83582 Revert "drm/i915: Avoid stalling on pending flips for legacy cursor updates"
"drm/i915: Allow nonblocking update of pageflips" should have been
split up, misses a proper commit message and seems to cause issues in
the legacy page_flip path as demonstrated by kms_flip.
"drm/i915: Make unpin async" doesn't handle the unthrottled cursor
updates correctly, leading to an apparent pin count leak. This is
caught by the WARN_ON in i915_gem_object_do_pin which screams if we
have more than DRM_I915_GEM_OBJECT_MAX_PIN_COUNT pins.
Unfortuantely we can't just revert these two because this patch series
came with a built-in bisect breakage in the form of temporarily
removing the unthrottled cursor update hack for legacy cursor ioctl.
Therefore there's no other option than to revert the entire pile :(
There's one tiny conflict in intel_drv.h due to other patches, nothing
serious.
Normally I'd wait a bit longer with doing a maintainer revert, but
since the minimal set of patches we need to revert (due to the bisect
breakage) is so big, time is running out fast. And very soon
(especially after a few attempts at fixing issues) it'll be really
hard to revert things cleanly.
Lessons learned:
- Not a good idea to rush the review (done by someone fairly new to
the area) and not make sure domain experts had a chance to read it.
- Patches should be properly split up. I only looked at the two
patches that should be reverted in detail, but both look like the
mix up different things in one patch.
- Patches really should have proper commit messages. Especially when
doing more than one thing, and especially when touching critical and
tricky core code.
- Building a patch series and r-b stamping it when it has a built-in
bisect breakage is not a good idea.
- I also think we need to stop building up technical debt by
postponing atomic igt testcases even longer. I think it's clear that
there's enough corner cases in this beast that we really need to
have the testcases _before_ the next step lands.
