[PATCH v2 00/37] drm: Deduplicate fb format information (v2)

[PATCH v2 00/37] drm: Deduplicate fb format information (v2)

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Second installment of my effort to remove the duplicated
depth/bpp/pixel_format from drm_framebuffer and just use
struct drm_format_info instead.

I tried to address all of the review feedback, and collect
up all the r-bs I already got. Thanks for the review, guys.

Changes since the last version are roughly:
* drm_framebuffer_init() now fails if the fb isn't properly prepared
* Applied mode cocciry all over to use fb->format more extensively
* Dropped a few i915 specific patches that were taken care of the
  previous item
* Took up Laurent's idea that we can just compare the fb->format
  pointers instead of comparing the fb->format->format values
* Added a new .get_format_info() hooks for drivers to provide custom
  format information + an quick example patch how we'd hook it up
  for i915 render compression support

[PATCH 01/37] drm/i915: Add local 'fb' variables

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Add a local 'fb' variable to a few places to get rid of the
'crtc->primary->fb' stuff. Looks neater and helps me with my poor
coccinelle skills later.

While at it switch over to using the pixel format rather than
depth+bpp.

[PATCH 03/37] drm/radeon: Use DIV_ROUND_UP()

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Use DIV_ROUND_UP() instead of hand rolling it. Just a drive-by change.

[PATCH 04/37] drm/mgag200: Add local 'fb' variable

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Add a local 'fb' variable to a few places to get rid of the
'crtc->primary->fb' stuff. Looks neater and helps me with my poor
coccinelle skills later.

[PATCH 07/37] drm/cirrus: Add some local 'fb' variables

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Add a local 'fb' variable to a few places to get rid of the
'crtc->primary->fb' stuff. Looks neater and helps me with my poor
coccinelle skills later.

[PATCH 09/37] drm/arm: Add local 'fb' variables

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Add a local 'fb' variable to a few places to get rid of the
'crtc->primary->fb' stuff. Looks neater and helps me with my ppor
coccinelle skills later.

In some places the local variable was already there, just not used
consistently.

Are you going to take the series through drm-misc or you want each sub-maintainer
to cherry pick the patches?

Probably easier to suck it all in one go. Unless drm-misc maintainers

[PATCH 10/37] drm/nouveau: Fix crtc->primary->fb vs. drm_fb fail

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

So it looks like the code is trying to pick between the passed in fb and
crtc->primary->fb based on that funky 'bool atomic'. But later it will
mix uses of both drm_fb (which was picked by the aforementioned logic)
and crtc->primary->fb. So looks like a bug to me. Let's make it use
drm_fb only.

Oh dear, set_base_atomic indeed expects that the passed-in fb is used, and
that drivers do _not_ update crtc->primary->fb. And drm core expects them
to do that, kinda, or at least allows it. I guess time to nuke all that
kgdb stuff as dead code and unused since obviously all broken.

But that's another story, this here seems to make some sense.

[PATCH 11/37] drm/nouveau: Add local 'fb' variables

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Add a local 'fb' variable to a few places to get rid of the
'crtc->primary->fb' stuff. Looks neater and helps me with my poor
coccinelle skills later.

[PATCH 12/37] drm/vmwgfx: Populate fb->dev before drm_framebuffer_init()

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

drm_framebuffer_init() will start to check that fb->dev is already
populated, so let's to that manually since vmwgfx isn't using
drm_helper_mode_fill_fb_struct().

[PATCH 13/37] drm: Pass 'dev' to drm_helper_mode_fill_fb_struct()

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Pass the drm_device to drm_helper_mode_fill_fb_struct() so that we can
populate fb->dev early. Will make it easier to use the fb before we
register it.

[PATCH v2 13/37] drm: Pass 'dev' to drm_helper_mode_fill_fb_struct()

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Pass the drm_device to drm_helper_mode_fill_fb_struct() so that we can
populate fb->dev early. Will make it easier to use the fb before we
register it.

[PATCH 14/37] drm/vmwgfx: Populate fb->pixel_format

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Stuff something semi-reasonable into fb->pixel_format. I had to guess
as to which formats we should pick. Did I guess correctly?

We can't quite use drm_mode_legacy_fb_format() due to the ARGB1555
vs. XRGB155 mess. However use of 'A' formats should imply per-pixel
alpha blending as far as KMS is concerned so I'm not at all sure we
want to have any 'A' formats exposed as opposed to just 'X' formats.
OTOH vmvgfx doesn't do planes, and so the core won't enforce that
these formats match any list of supported formats, so the choice
shouldn't be super important at this point.

Yup, kernel-doc even says that drm_framebuffer_init() must be the very
last thing or races. I've done a full audit, and qxl&virtio are the only
two offenders. On both patches:

[PATCH 17/37] drm/i915: Set fb->dev early on for inherited fbs

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We want the fbs inherited from the BIOS to be more or less fully working
prior to actually registering them. This will allow us to just pass the
fb to various helper function instead of having to pass all the
different parameters separately.

I guess eventually we'll grow a WARN_ON(!fb->dev) in
drm_framebuffer_init() to make sure these don't escape? Anyway:

[PATCH v2 18/37] drm: Populate fb->dev from drm_helper_mode_fill_fb_struct()

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Populating fb->dev before drm_framebuffer_init() allows us to use
fb->dev already while validating the framebuffer. Let's have
drm_helper_mode_fill_fb_struct() do that for us.

Also make drm_framebuffer_init() warn us if a different device
pointer is passed to it than was passed to
drm_helper_mode_fill_fb_struct().

v2: Reject fbs with invalid fb->dev (Laurent)

[PATCH v2 19/37] drm: Store a pointer to drm_format_info under drm_framebuffer

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

To avoid having to look up the format information struct every time,
let's just store a pointer to it under drm_framebuffer.

v2: Don't populate the fb->format pointer in drm_framebuffer_init().
    instead we'll treat a NULL format as an error later

Why not use drm_mode_fill_fb_struct here? This just seems to be bad
copypasta in both cases ...

That it is. I was hoping I'd trick the vmware folks into fixing it by
posting this series. One issue is that this code still used the old
mode_cmd struct rather than the new mode_cmd2 struct. So the fix may
not be entirely trivial, and hence I was hoping people who care
about the driver would do it.

I gave it a try and it required touching too much code for my limited (or 
rather non-existing) knowledge of the driver. Pretty please to the vmwgfx 
maintainers, could you fix this ? vmwgfx is the last driver still relying on 
the old mode_cmd structure.

Well you all managed to trick me into typing it, and it didn't seem too
bad. Pretty much just mechanically switching everything from mode_cmd to
mode_cmd2. Maybe I've touched too many drm drivers for big refactorings
and I have too low standards for what's involved ;-)

Patch submitted, review very much appreciated. And I'll try to ping
Sinclair on irc once he shows up for testing.

If you change the earlier patch to just use fill_fb_struct this one here
isn't needed.

[PATCH 21/37] drm/i915: Populate fb->format early for inherited fbs

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Make sure the framebuffer format info is available as early as possible
for fbs we inherit from the BIOS. This will allow us to use the fb as
if it was fully formed before we register it.

Do we really want to hand-roll this all, or could we somehow reuse
fill_fb_struct? Or will this all go away again?

I'll reserve judgement until the end, but this here looks correct ;-)

Yeah, I think we'll want to flip all of this over to using
fill_fb_struct(). Just didn't have the energy to look into that yet,
and the series was already getting too long anyway. So figured I'd save
that for the next round.

Looking at the end result I think doing the fill_fb_struct a pile earlier
would be nice. Or at least extract an set_fb_format helper or whatever to
set ->format and ->dev.

Needs a better name than set_fb_format though ;-)

Anyway, follow-up work.

[PATCH 22/37] drm: Reject fbs w/o format info in drm_framebuffer_init()

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Any framebuffer that doesn't have proper format information when
drm_framebuffer_init() is called is a bug. Let's warn and return
an error to avoid oopsing the kernel later due to dereferencing the
NULL fb->format pointer.

[PATCH 24/37] drm/i915: Eliminate the ugly 'fb?:' constructs from the ilk/skl wm code

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Don't access plane_state->fb until we know the plane to be visible.
It it's visible, it will have an fb, and thus we don't have to
consider the NULL fb case. Makes the code look nicer.

Why do we still look for crtc_state->active here? Sounds like a bug in
proper validating our wm needs. Anway, change itself looks good.

Yeah, unfortunately that thing is still broken all over :( There are
broken assumptions about this higher up as well, so fixing this will
involve actual work I fear.

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Get the format information via the neat fb->format pointer rather than
doing a linear search over all the format info structures.

Could have done a smaller conversion with info = fb->format. Meh.

[PATCH 28/37] drm/i915: Store a pointer to the pixel format info for fbc

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Rather than store the pixel format and look up the format info as
needed,  let's just store a pointer to the format info directly
and speed up our lookups.

[PATCH 29/37] drm: Add drm_framebuffer_plane_{width,height}()

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Add variants of drm_format_plane_{width,height}() that take an entire fb
object instead of just the format. These should be more efficent as they
can just look up the format info from the fb->format pointer rather than
having to look it up (using a linear search based on the format).

[PATCH v2 32/37] drm: Nuke fb->bits_per_pixel

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Replace uses of fb->bits_per_pixel with fb->format->cpp[0]*8.
Less duplicated information is a good thing.

Note that I didn't put parens around the cpp*8 in the below cocci script,
on account of not wanting spurious parens all over the place. Instead I
did the unsafe way, and tried to look over the entire diff to spot if
any dangerous expressions were produced. I didn't see any.

There are some cases where previously the code did X*bpp/8, so the
division happened after the multiplication. Those are now just X*cpp
so the division effectively happens before the multiplication,
but that is perfectly fine since bpp is always a multiple of 8.

[PATCH v3 32/37] drm: Nuke fb->bits_per_pixel

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Replace uses of fb->bits_per_pixel with fb->format->cpp[0]*8.
Less duplicated information is a good thing.

Note that I didn't put parens around the cpp*8 in the below cocci script,
on account of not wanting spurious parens all over the place. Instead I
did the unsafe way, and tried to look over the entire diff to spot if
any dangerous expressions were produced. I didn't see any.

There are some cases where previously the code did X*bpp/8, so the
division happened after the multiplication. Those are now just X*cpp
so the division effectively happens before the multiplication,
but that is perfectly fine since bpp is always a multiple of 8.

[PATCH v2 33/37] drm: Nuke fb->pixel_format

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Replace uses of fb->pixel_format with fb->format->format.
Less duplicated information is a good thing.

Note that coccinelle failed to eliminate the
"/* fourcc format */" comment from drm_framebuffer.h, so I had
to do that part manually.

[PATCH v3 33/37] drm: Nuke fb->pixel_format

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Replace uses of fb->pixel_format with fb->format->format.
Less duplicated information is a good thing.

Note that coccinelle failed to eliminate the
"/* fourcc format */" comment from drm_framebuffer.h, so I had
to do that part manually.

    Rebase due to earlier removal of many fb->pixel_format uses,
    including the 'fb->format = drm_format_info(fb->format->format);'
    snafu
v3: Adjusted the semantic patch a bit and regenerated due to code
    changes

[PATCH 34/37] drm: Replace 'format->format' comparisons to just 'format' comparisons

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Rather than compare the format u32s of two format infos, we can direclty
compare the format info pointers themselves. Noramlly all the ->format
pointers all point to somwehere in the big array, so this is a valid
way to test for equality.

Also drivers may want to point ->format at a private format info struct
instead (eg. for special compressed formats with extra planes), so
just comparing the pixel format values wouldn't necessaritly even work.
But comparing the pointers will also take care of that case.

[PATCH 35/37] drm: Eliminate the useless "non-RGB fb" debug message

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

No point in spamming the log whenever a non-RGB fb is being
constructed. And since there's nothing to do anymore that
fb->bits_per_pixel and fb->depth are gone, we can just kill
off this entire piece of code.

[PATCH 36/37] drm: Add mode_config .get_format_info() hook

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Allow drivers to return a custom drm_format_info structure for special
fb layouts. We'll use this for the compression control surface in i915.

I assume you meant drm_get_format_info()

Do we need the dev pointer ?

It would be useful to document how this function differs from 
drm_format_info(). I also wonder whether it would make sense to completely 
replace drm_format_info() to avoid keeping two separate but very similar 
functions.

Yes.

Not at the moment. I was thinking we might allow drivers to return a
different set of formats based on the device type, but I'm not sure
that's all that useful since drivers will have to check for unsupported
formats anyway in .fb_create(). The only use case might be if you need
to select between two different format info structs based on the device
type, because you simply can't tell the formats apart based on the
mode_cmd. But that sort of thing feels like a bad idea to me, and might
as well just require that you must be able to tell formats that require
different format intos apart based on the mode_cmd (eg. by having
different modifiers on them).

So I guess we could just drop the 'dev' argument to make it harder for
people to make that sort of mistake.

Yeah, that is basically what I was thinking. But I didn't feel like
doing that myself as it looked like that might involve actual work
in some of the drivers. I figured I'd leave it up to whoever cares
about said drivers.

I think that's a good idea, yes.

Which driver(s) are you thinking about ? If we want to make 
drm_get_format_info() the default we obviously need to pass modifiers 
directly, as in most cases we won't have a struct drm_mode_fb_cmd2 to pass to 
the function. If we remove the dev argument you could just pass NULL modifiers 
in most cases, I don't think that would involve much rework in drivers.

The ones that my cocci stuff couldn't convert over to fb->format.

fb->format is probably the right choice in most cases. But some drivers
seemed to have some kind of internal format info struct instead which
was in the way of doing a trivial conversion. I didn't want to start
doing non-trivial conversions since the series was already way too big
as is.

How about at least making drm_get_format_info() the default but converting 
what can be converted with coccinelle, and marking drm_format_info() as 
deprecated ?

That's an interesting point I wanted to also mention. We have drivers that 
include formats information tables duplicating the one in the DRM core, with 
additional driver-specific information (see rcar_du_format_info() in 
drivers/gpu/drm/rcar-du/rcar_du_kms.c for instance). I wonder whether it would 
be possible to come up with a simple API that would allow providing those 
driver-specific data to the core, and get them back from the 
drm_get_format_info() function.

I think I already did everything except the "mark as deprecated" part.
And adding that last bit into the patch would be trivial.

I suppose drivers could just embed the drm_format_info into some bigger
structure which has additional information. One thing that makes that a
little harder is the fact that the regular format info structures aren't
exported to drivers in a way that they could just:

static const struct my_format_info format_info_foo {
	.base = drm_format_info_foo,
	...
};

So they'd have to duplicate the information which is maybe a little
error prone. OTOH that problem already exists to some degree with my
.get_format_info() hook (which somewhat makes me think we should just
put all of that stuff into drm_fourcc.c).

But I suppose exporting the drm_format_info structs could be done as
well, and then drivers could do whatever they want.

[PATCH v2 36/37] drm: Add mode_config .get_format_info() hook

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Allow drivers to return a custom drm_format_info structure for special
fb layouts. We'll use this for the compression control surface in i915.

v2: Fix drm_get_format_info() kernel doc (Laurent)
    Don't pass 'dev' to the new hook (Laurent)

[PATCH 37/37] drm/i915: Implement .get_format_info() hook for CCS

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

By providing our own format information for the CCS formats, we should
be able to make framebuffer_check() do the right thing for the CCS
surface as well.

Note that we'll return the same format info for both Y and Yf tiled
format as that's what happens with the non-CCS Y vs. Yf as well. If
desired, we could potentially return a unique pointer for each
pixel_format+tiling+ccs combination, in which case we immediately be
able to tell if any of that stuff changed by just comparing the
pointers. But that does sound a bit wasteful space wise.

I was hoping to see that patch as well :-). If you're adding the new fb
modifiers, I think it'd make sense to make it part of this series.
Alternatively, I can take 36, and 37 and make it part of my series, then
integrate that last bit. It's up to you.

It sort of seems like somewhat of a waste to provide this if implementations are
allowed to return NULL. It's like saying, "DRM core will check stuff for you if
you provide the info, but you don't have to do it if you don't want to." If
that's the case you may as well provide a driver hook to just do the check, ie.
s/mod_funcs->get_format_info/mode_functs->check_format/

The core will check the stuff anyway. The NULL just means "I don't have
any special requirements, so the core format info will be sufficient".

Drivers already have to do a bunch of checks in .fb_create(). In
addition the core does some basic sanity checks before the driver
even sees the mode_cmd (except for the new .get_format_info() hook
that is). I don't want every driver to have to duplicate all of these
basic sanity checks.

One alternative to this scheme would be have a helper function that
every driver would call in .fb_create() that would do these basic sanity
checks. That way we wouldn't need the extra hook, with a slight risk
that driver would forget to call the helper.

I think when fb modifiers were started the idea was that we would later 
partition our vendor bit space for different classes of things and have 
helper functions to extract the tiling, etc, from them.

For example have first 3-4 bits represent the tiling, then in this case 
one bit for CCS, etc.

Have you considered that when adding these ones, and concluded this 
different scheme is better for some reason?

Regards,

Tvrtko

I haven't considered anything. And obviously this patch isn't meant
for inclusion as is. I just needed sometime to make it compile.

Generally I don't think adding magic meaning for individual bits for
things like this is a particularly good idea. Every time I've seen a
scheme like that it has eventually turned ugly on account of running
out of bits in one place or another.

No idea on the status of this series. Just noticed new modifiers by 
accident and remembered the early discussions.

I think in this case it might be much better. You just need one more 
feature which intersects with tiling and ccs to make the list not very 
manageable.

I've pushed up to here to drm-misc-next. Thanks for the reviews.

I re-ran spatch to regenerate some of the later patches as there had
been a bit of churn in the code. I've reposted the changed patches,
and if no one screams I'll be pushing the rest tomorrowish.

Thanks for the reviews everyone.
