Hi all,
Here's the next round of devm_drm_dev_alloc. Big changes:
- lots of acks, reviews and some testing tags. Very much appreciated!
- I dropped the core driver patch, and hence also the patches for vgem,
vkms and i915-selftests. That needs more discussions first.
- I started to convert some of the other drivers that still used
drm_dev_alloc to the shiny new world, with a pile of cleanups on top. So
lots more patches to test and review.
Looking at git grep output for drm_dev_alloc() I think there's enough room
for another few similarly sized patch series. I'm kinda using that also to
survey the state of drivers, so I have a good idea what drmm_ versions for
various modeset objects should look like. Atm still not sure how to best
approach this, with the mix of drivers we do have: Some use devm_kzalloc,
some explicit kzalloc + kfree in cleanup code, some embedded it somewhere
else.
As usual, review, testing and comments very much appreciated.
Cheers, Daniel

* [PATCH 01/59] drm: Add devm_drm_dev_alloc macro

Add a new macro helper to combine the usual init sequence in drivers,
consisting of a kzalloc + devm_drm_dev_init + drmm_add_final_kfree
triplet. This allows us to remove the rather unsightly
drmm_add_final_kfree from all currently merged drivers.
The kerneldoc is only added for this new function. Existing kerneldoc
and examples will be udated at the very end, since once all drivers
are converted over to devm_drm_dev_alloc we can unexport a lot of
interim functions and make the documentation for driver authors a lot
cleaner and less confusing. There will be only one true way to
initialize a drm_device at the end of this, which is going to be
devm_drm_dev_alloc.
v2:
- Actually explain what this is for in the commit message (Sam)
- Fix checkpatch issues (Sam)

* [Intel-gfx] [PATCH 01/59] drm: Add devm_drm_dev_alloc macro
@ 2020-04-15 7:39 ` Daniel Vetter

Sam Ravnborg
Add a new macro helper to combine the usual init sequence in drivers,
consisting of a kzalloc + devm_drm_dev_init + drmm_add_final_kfree
triplet. This allows us to remove the rather unsightly
drmm_add_final_kfree from all currently merged drivers.
The kerneldoc is only added for this new function. Existing kerneldoc
and examples will be udated at the very end, since once all drivers
are converted over to devm_drm_dev_alloc we can unexport a lot of
interim functions and make the documentation for driver authors a lot
cleaner and less confusing. There will be only one true way to
initialize a drm_device at the end of this, which is going to be
devm_drm_dev_alloc.
v2:
- Actually explain what this is for in the commit message (Sam)
- Fix checkpatch issues (Sam)

Allows us to drop the cleanup code on the floor.
Sam noticed in his review:
> With this change we avoid calling pci_disable_device()
> twise in case vbox_mm_init() fails.
> Once in vbox_hw_fini() and once in the error path.
v2: Include Sam's review remarks

Also allows us to simplify the unroll code since the drm_dev_put
disappears.

We already have it in v3d_dev->drm.dev with zero additional pointer
chasing. Personally I don't like duplicated pointers like this
because:
- reviewers need to check whether the pointer is for the same or
different objects if there's multiple
- compilers have an easier time too
But also a bit a bikeshed, so feel free to ignore.

* [Intel-gfx] [PATCH 09/59] drm/v3d: Delete v3d_dev->dev

We already have it in v3d_dev->drm.dev with zero additional pointer
chasing. Personally I don't like duplicated pointers like this
because:
- reviewers need to check whether the pointer is for the same or
different objects if there's multiple
- compilers have an easier time too
But also a bit a bikeshed, so feel free to ignore.

We already have it in v3d_dev->drm.dev with zero additional pointer
chasing. Personally I don't like duplicated pointers like this
because:
- reviewers need to check whether the pointer is for the same or
different objects if there's multiple
- compilers have an easier time too
To avoid having to pull in some big headers I implemented the casting
function as a macro instead of a static inline. Typechecking thanks to
container_of still assured.
But also a bit a bikeshed, so feel free to ignore.

We already have it in v3d_dev->drm.dev with zero additional pointer
chasing. Personally I don't like duplicated pointers like this
because:
- reviewers need to check whether the pointer is for the same or
different objects if there's multiple
- compilers have an easier time too
To avoid having to pull in some big headers I implemented the casting
function as a macro instead of a static inline. Typechecking thanks to
container_of still assured.
But also a bit a bikeshed, so feel free to ignore.
v2: More parens for v3d_to_pdev macro (checkpatch)

Also init the fbdev emulation before we register the device, that way
we can rely on the auto-cleanup and simplify the probe error code even
more.
v2: Rebase on top of Thomas' patches to remove the return value from

We're mostly there already, just a handful of places that didn't use
the to_udl container_of cast. To make sure no new appear, don't set
->dev_private.

* [Intel-gfx] [PATCH 27/59] drm/qxl: Don't use drm_device->dev_private
@ 2020-04-15 7:40 ` Daniel Vetter

Upcasting using a container_of macro is more typesafe, faster and
easier for the compiler to optimize.

Upcasting using a container_of macro is more typesafe, faster and
easier for the compiler to optimize.
v2: Move misplaced removal of double-assignment to this patch (Sam)

Komeda uses the component framework, which does open/close a new
devres group around all the bind callbacks. Which means we can use
devm_ functions for managing the drm_device cleanup, with leaking
stuff in case of deferred probes or other reasons to unbind
components, or the component_master.
Also note that this fixes a double-free in the probe unroll code, bot
drm_dev_put and kfree(kms) result in the kms allocation getting freed.
Aside: komeda_bind could be cleaned up a lot, devm_kfree is a bit
redundant. Plus I'm not clear on why there's suballocations for
mdrv->mdev and mdrv->kms. Plus I'm not sure the lifetimes are correct
with all that devm_kzalloc usage ... That structure layout is also the
reason why komeda still uses drm_device->dev_private and can't easily
be replaced with a proper container_of upcasting. I'm pretty sure that
there's endless amounts of hotunplug/hotremove bugs in there with all
the unprotected dereferencing of drm_device->dev_private.

Also remove the now no longer needed build bug on since that's already
not needed anymore with drmm_add_final_kfree. Conversion to managed
drm_device cleanup is easy, the final drm_dev_put() is already the
last thing in both the bind unbind as in the unbind flow.
Also, this relies on component.c correctly wrapping bind&unbind in
separate devres groups, which it does.

Luckily we're already well set up in the main driver, with
drm_dev_put() being the last thing in both the unload error case and

- Need to embedded the drm_device, but for now we keep the usual
pointer chasing.
- No more devm_kzalloc, which fixes a lifetime issues on driver
remove.
- No more drm_dev_put, that's done by devm_ now.

This is a prep step to convert arc over to the simple kms helpers, for
now we just use this as an embedding container to drop all the various
allocations. Big change is the removal of the various devm_kzalloc,
which have the wrong lifetimes anyway.

* [Intel-gfx] [PATCH 42/59] drm/arc: Embedded a drm_simple_display_pipe

This is a prep step to convert arc over to the simple kms helpers, for
now we just use this as an embedding container to drop all the various
allocations. Big change is the removal of the various devm_kzalloc,
which have the wrong lifetimes anyway.

drm_connector_register does nothing before drm_dev_register(), it
is meant for hotpluggable connectors only. Same for the unregister side.

With autocleanup through drm_device management we can delete all the
code. Possible now that there's no confusion against devm_kzalloc'ed
structures anymore.
I inlined arcpgu_setup_mode_config because it's tiny and the newly
needed return value handling would have been more ...

* [Intel-gfx] [PATCH 45/59] drm/arc: Use drmm_mode_config_cleanup

With autocleanup through drm_device management we can delete all the
code. Possible now that there's no confusion against devm_kzalloc'ed
structures anymore.
I inlined arcpgu_setup_mode_config because it's tiny and the newly
needed return value handling would have been more ...

Simple pipe helpers only have an enable and disable hook, no more
mode_set_nofb. Call it from our enable hook to align with that
conversions.
Atomic helpers always call mode_set_nofb and enable together, so
there's no functional change here.

Really straighforward, only slight issue is that the sim connector is
created after the pipe is set up, so can't use the helpers perfectly
yet. Subsequent patches will fix that.
Aside from lots of deleting code no functional changes in here.

* [Intel-gfx] [PATCH 47/59] drm/arc: Convert to drm_simple_kms_pipe_helper

Really straighforward, only slight issue is that the sim connector is
created after the pipe is set up, so can't use the helpers perfectly
yet. Subsequent patches will fix that.
Aside from lots of deleting code no functional changes in here.

First it's redundant, fb and crtc are only ever both set or not set.
2nd, the atomic_check code in simple display pipe helpers guarantees
that this never happens. So nice bugfix for arcpgu driver here, since
it was lacking a call to drm_atomic_helper_check_plane_state().

almost all the code is gone.

* [Intel-gfx] [PATCH 51/59] drm/arc: Inline remaining files
@ 2020-04-15 7:40 ` Daniel Vetter
0 siblings, 0 replies; 317+ messages in thread
From: Daniel Vetter @ 2020-04-15 7:40 UTC (permalink / raw)
To: Intel Graphics Development; +Cc: Daniel Vetter, DRI Development, Daniel Vetter
At less than 500 lines total feels like the right thing to do.
Also noticed that the simple wrapper around drm_connector_cleanup can
be dropped.

As usual, we can drop the drm_dev_put() and need to embed the
drm_device. Since it's so few, also go right ahead and leave
drm_device->dev_private set to NULL, so that we always use the
container_of() upcast, which is faster anyway.

* [PATCH 55/59] drm/aspeed: Use devm_drm_dev_alloc

As usual, we can drop the drm_dev_put() and need to embed the
drm_device. Since it's so few, also go right ahead and leave
drm_device->dev_private set to NULL, so that we always use the
container_of() upcast, which is faster anyway.

This is leftovers from the old drm_driver->load callback
upside-down issues. It doesn't do anything for not-hotplugged
connectors since drm_dev_register takes care of that.

This gets unmapped as part of the automatic pci_disable_device(), I guess?
Do we need drm_dev_enter()/_exit() to make I/O work reliably?

Every other week, I felt an urge to send out this patch. Thank you so

bochs or arc come into my mind.

Yup, once you go with pcim_enable_device all pci_ functions on that
device become manged and auto-cleanup.

That does nothing without drm_dev_unplug(), which has the annoying
side effect that it also shuts up stuff like
drm_atomic_helper_shutdown for module unload. And developers really
want their devices to be shut off on driver unload. So yeah
unfortunately we currently can decide between "correct for hotunplug"
and "convenient for driver unload for driver authors". I'm not sure
what to best do here, since all options are kinda not great for one
use-case or the other.

So if we'd split up drm_dev_unplug into drm_dev_unregister +
drm_dev_mark_unplugged or whatever the options would be:
drm_atomic_helper_shutdown(); /* and other hw shut down */
drm_dev_unregister();
drm_dev_mark_unplugged();
Kinda annoying since userspace might race with us, so we might still
have an active fb (in sw tracking at least) that we need to clean up
again later on. Plus shutting down hw before we unregister is going to
make the hotunplug confusion for userspace even more a mess.
Next option:
drm_dev_unregster();
/* shut down hw */
drm_dev_mark_unplugged();
This just wastes time since if we're really unplugged we'll do lots of
io attempts that go nowhere because the device is gone already.
They'll all time out (if the bus subsystem/hw for our driver works
correctly at least). Plus userspace can still sneak in and do stupid
stuff I think while we're not looking.
Next up:
drm_dev_unregister();
drm_dev_mark_unplugged();
drm_atomic_helper_shutdown();
This is a bit silly since all the shutdown code now does is shut down
sw state, and never touches hw (if the driver is fully annotated with
drm_dev_enter/exit).
One option might be that we slap a lot more drm_dev_enter/exit around
the top-level ioctls (to at least stop the userspace races with driver
unload), and allow drivers to still shut down stuff internally.
tldr; it's all still a bit a mess.

arc I have (later in the series), bochs I feel like is maybe a bit too
big. I'd put the limit for tiny well below 1kloc including whitespace
and all that. bochs might be a candidate once we've helperized a few
more things perhaps.
btw I drmm_ version of vram helpers would help a bunch of these drivers I think.

arc I have (later in the series), bochs I feel like is maybe a bit too
big. I'd put the limit for tiny well below 1kloc including whitespace
and all that. bochs might be a candidate once we've helperized a few
more things perhaps.
btw I drmm_ version of vram helpers would help a bunch of these drivers I think.

Right now they all still need to be here because of the
devm_drm_dev_alloc patch 1 adds. After that I guess I can split up,
but it's kinda more work. The series is really "clean up driver
load/unload code around drm_device", and for some of the older drivers
there's a _lot_ that can be done.

Yeah, and I think the trouble there is that it contains an
epaper-specific panel abstraction. I think that's pushing it over the
edge. I think we've talked about subclassing drm_panel with
bus/device-specific stuff, that might be an option if this gets out of
hand.
Also I think we should be much stricter with putting drivers into
tiny/ than moving them out. Just so we avoid endless ping-pong, e.g.
for drivers that I can't make really tiny I wont bother with moving
them to tiny/

Yeah, and I think the trouble there is that it contains an
epaper-specific panel abstraction. I think that's pushing it over the
edge. I think we've talked about subclassing drm_panel with
bus/device-specific stuff, that might be an option if this gets out of
hand.
Also I think we should be much stricter with putting drivers into
tiny/ than moving them out. Just so we avoid endless ping-pong, e.g.
for drivers that I can't make really tiny I wont bother with moving
them to tiny/

We have "DRM: ARC: add HDMI 2.0 TX encoder support" which
adds another platform driver to drm/arc/
This speaks against the move to tiny IMO

Indeed that's an interesting question, see v3 series here:
https://lists.freedesktop.org/archives/dri-devel/2020-April/262352.html
BTW should I pull that series in my tree and send you a pull-request
or that kind of change needs to go through another tree?
Also I'd like to test the change we discuss here to make sure stuff
still works. Once we do that I'll send an update. Any hint on
when that change needs to be acked/nacked?

Looking at this patch series, feels a bit like hand-rolling of bridge
code, badly. We should get away from that.
Once you have that I think the end result is tiny enough that it can
stay, bridges intergrate quite well into simple display pipe drivers.

Simplest is if this can all land through drm-misc, is arc not
maintained in there? And there's plenty of time for testing, I'm just
slowly crawling through the tree to get everything polished and
cleaned up in this area.

This seems to be missing the conversion of the iomap_range call to

Maybe rename 'offset' of 'dev_offset' to make the relationship clear.

While convenient, I somewhat dislike the use of void* variables. I'd use

Maybe rename 'offset' of 'dev_offset' to make the relationship clear.

While convenient, I somewhat dislike the use of void* variables. I'd use
unsigned char* for container and do an explicit cast to struct
drm_device* here.

Hm, I see the point of this (and the dev_field below, although I'd go
with dev_member there for some consistency with other macros using
offset_of or container_of), but I'm not sure about the dev_ prefix.
Drivers use that sometimes for the struct device *, and usage for
struct drm_device * is also very inconsistent. I've seen ddev, drm,
dev and base (that one only for embedded structs ofc). So not sure
which prefix to pick, aside from dev_ seems the most confusing. Got
ideas?

I thought ever since C89 the explicit recommendation for untyped
pointer math has been void *, and no longer char *, with the spec
being explicit that void * pointer math works exactly like char *. So
not clear on why you think char * is preferred here. I'm also not
aware of any other kernel code that casts to char * for untyped
pointer math. So unless you have some supporting evidence, I'll skip
this one, ok?

We have pdev for the PCI device, dev for the abstract device, and things
like mdev for struct mga_device in mgag200. So I'd go with ddev. I don't
like drm, because it could be anything in DRM. I guess struct drm_driver
is more 'drm' than struct drm_device.
But all of this is bikeshedding. It's probably best to keep the patch
as-is, and maybe rename variables later if we ever find consent on the
naming.

From how I understand the C spec, I think it's the other way around. I
had to look up the sections from the C11 spec:
Sec 6.5.6 Additive operators
2 For addition, either both operands shall have arithmetic type, or
one operand shall be a pointer to a complete object type and the
other shall have integer type. (Incrementing is equivalent to adding
1.)
About void it says that it's not a complete type.
Sec 6.2.5 Types
19 The void type comprises an empty set of values; it is an incomplete
object type that cannot be completed.
Arithmetic on void* is a gcc extension AFAIK.

I'm really just bikeshedding on things I'd have done differently.

I'm really just bikeshedding on things I'd have done differently.

bikeshedding - I know.
But reading code is is quite natural for me that drm equals the central
drm_device data structure. Maybe thats because this was is in the code
I started looking at.
So as an example:
drm_err(drm, "bla bla\n");
This parses nicely and is easy to type and get right.
And matches nicely that drm_device => drm.
But bikeshedding - I will go to bed...
(Whatever is the conclusion we should not hold back the patch in
questions).

The other patches do not add any error message when devm_drm_dev_alloc()
fails and driver core will log that driver init failed.
So the pr_err() above should be dropped.
I know it comes from qxl_device_init() but that does not make it a good
idea.
With this fixed:

The other patches do not add any error message when devm_drm_dev_alloc()
fails and driver core will log that driver init failed.
So the pr_err() above should be dropped.
I know it comes from qxl_device_init() but that does not make it a good
idea.

Subject needs a small adjustment:
drm/arc: arcgpu: Switch to devm_drm_dev_alloc
There is no driver named arcgpu - so it should
not be used like in thins patch.
With this detail fixed:

drm_simple_* will create a DRM_MODE_ENCODER_NONE - so the
encoder type will be different.
If this has any practical implications I dunno.

I looked at drm_simple_kms_plane_atomic_check() - which I assume you
refer to. And I see no code that will guarantee both.
What have I missed?

Detail. In the old code ant error was converted to -ENODEV.
The new code let the error code bubble up - which is better.
But this is a small change that is not in the changelog.

This looks like code that belongs in one of the former patches.
Not that it matters much but anyway.

This put is missing when arcpgu_drm_hdmi_init() was inlined.
At least in the (!bridge) case - I did not look at the surrounding code.

I do not see anything that documents that it is OK to init min/max
width/heigh not funcs before drmm_mode_config_init() is called.
Maybe drmm_mode_config_init() gain an memset(drm->mode_config),
and we loose all the assingments from before the call to init().
Also most (all?) other users of drmm_mode_config_init()
set them after the call to drmm_mode_config_init().
So re-order here and then embed while you are touching the code again.

width/heigh not funcs before drmm_mode_config_init() is called.
Maybe drmm_mode_config_init() gain an memset(drm->mode_config),
and we loose all the assingments from before the call to init().
Also most (all?) other users of drmm_mode_config_init()
set them after the call to drmm_mode_config_init().
So re-order here and then embed while you are touching the code again.

Hmmm....
mode_set_nofb() is only called from drm_atomic_helper - crtc_set_mode()
crtc_set_mode() is only called from drm_atomic_helper_commit_modeset_disables()
drm_atomic_helper_commit_modeset_disables() is called from drm_atomic_helper_commit_tail()
So it seems you are right.

Ok, since we can't agree on dev vs ddev vs drm vs something else I just
left it as-is. We can always repaint this later on.

Hm I know we're inconsistent here, but some drivers have error logging on
all branches, some dont. I'm just trying to go with the prevailing style.

Any updates on testing this pile here? First patch landed now, and I've
started to push driver patches. So would be good to get this sorted out
too.

Only reason I've done it like this is that it saves a few lines of diff
compared to other options.
Wrt calling stuff the wrong way round: We pretty much assume throughout
that structures are allocated with kzalloc, none of our _init() functions
in drm have a memset. We'd break the world if we start doing memset() in
random _init() functions I think.
Also the main aspeed_gfx_load() function is quite long already, smashing
more random stuff in there won't help it's readability.
Anyway I don't care, if you insist I'm happy to repaint this in whatever
color choice you deem best :-)

Only reason I've done it like this is that it saves a few lines of diff
compared to other options.
Wrt calling stuff the wrong way round: We pretty much assume throughout
that structures are allocated with kzalloc, none of our _init() functions
in drm have a memset. We'd break the world if we start doing memset() in
random _init() functions I think.
Also the main aspeed_gfx_load() function is quite long already, smashing
more random stuff in there won't help it's readability.
Anyway I don't care, if you insist I'm happy to repaint this in whatever
color choice you deem best :-)

I guess we'll be able to test it in a week or two from now.

Hi Daniel,
I've already tested it (and found several issues), so please check my reply here:
https://www.mail-archive.com/linux-snps-arc@lists.infradead.org/msg07403.html
Not sure why you didn't receive my reply (probably the reason is because it was sent to your @ffwll.ch mail instead of @intel.com one).

Hi Eugeniy,
Apologies, somehow I missed your mail. I looked at the code again, and I
think I fumbled something. Does the below diff help to prevent the issues?

Hi Eugeniy,
Thanks for testing. I looked at the second one (I hoped it would just
magically disappear) and I still don't understand what's going on
there. My patch series isn't touching that area at all, so really
confused.
I squashed in the bugfix from the previous round into the right
patches, and pushed a branch with just the arcpgu changes here:
https://cgit.freedesktop.org/~danvet/drm/log/?h=for-eugeniy
Maybe it's something in my pile of not-so-tested stuff :-)
Can you pls test this? And if it still fails, try to bisect where it breaks?
Thanks, Daniel

Hi Eugeniy,
Thanks for testing. I looked at the second one (I hoped it would just
magically disappear) and I still don't understand what's going on
there. My patch series isn't touching that area at all, so really
confused.
I squashed in the bugfix from the previous round into the right
patches, and pushed a branch with just the arcpgu changes here:
https://cgit.freedesktop.org/~danvet/drm/log/?h=for-eugeniy
Maybe it's something in my pile of not-so-tested stuff :-)
Can you pls test this? And if it still fails, try to bisect where it breaks?
Thanks, Daniel

Hi Daniel,
I've got pretty strange results so I need some time to investigate it and probably retest.
I'll send you update in a few days.

Hi Eugeniy,
Very much appreciated, and kinda expected. That 2nd backtrace really
confuses me, so "something strange is going on" and the bisect looks
funny is within expectations. Hopefully we can track down what's going
on.
Thanks, Daniel

[Sorry just realized I never replied on-list for this here]
drm_device very much has a dev_ and there's some other drivders with
this pattern too. Plus I think it's more consistent with the other
macros in here. For simple drivers where there's only 1 structure I
agree though, so if you insist I can follow up with a patch. Fixing
this in-series is imo too much trouble for the benefit, every single
patch would need to be redone ...

The naming is my personal choice - others have different opinions.
And since we did not universially agree on dev_to_* versus to_* for the
main driver structure there is no need to adjust.
For me it is just that the main driver structure is more than a device
thingy and I like the short naming. But it seems you, Thomas + more
prefer dev_to_* so maybe I should adjust so we are a little more
aligned.
So it is considered so the patch is obviously:
