[PATCH 00/32] drm: Deduplicate fb format information

[PATCH 00/32] drm: Deduplicate fb format information

[ville.syrjala]

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

This series aims to remove the duplicated format information stored under
drm_framebuffer (depth,bits_per_pixel,pixel_format), and instead we just
use the drm_format_info structure. And we store a pointer to the approriate
drm_format_info under drm_framebuffer so that we don't have to do expensive
linear searches through the big array.

Quite of bit of this was cocci magic, and I've tried to keep the cocci
patches pure of manual tinkering in case someone needs to rerun them.
I had some issues with cocci behaving like an idiot, so I've included
a bunch of hand rolled patches up front to make life easier for it.

I've smoke tested this on i915, and compile tested on everything else
(I hope).

Entire series available here:

[PATCH 01/32] 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 05/32] drm/ast: Add local 'fb' variables

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

[PATCH 10/32] 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.

[PATCH 11/32] 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 12/32] 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 14/32] 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.

[PATCH 17/32] 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.

[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().

[PATCH 21/32] 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.

[PATCH 27/32] drm/i915: Replace drm_format_num_planes() with fb->format->num_planes

[ville.syrjala]

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

No need to look up the format info to get the number of planes, just
use fb->format->num_planes directly.

[PATCH 28/32] 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 31/32] 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 32/32] drm: Nuke fb->pixel_format

[ville.syrjala]

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

Replace uses of fb->bits_per_pixel 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.

The vmgfx driver should really be converted to using struct drm_mode_fb_cmd2 
through the whole code instead of converting struct drm_mode_fb_cmd2 to struct 
drm_mode_fb_cmd in vmw_kms_fb_create(). I gave it a go a few months back but 
the structure is passed around so many functions that conversion requires more 
knowledge about the driver than I have. I don't expect you to fix that, but it 
would be nice if Sinclair or Thomas could give it a go.

With this drivers will start relying on fb->format. I believe we should commit 
to provide a non-NULL format info to avoid having to sprinkle NULL checks in 
all drivers. Should drm_framebuffer_init() return an error in that case ? Or 
do we guarantee already through another mean that the pixel format is valid 
and will always lead to a non-NULL format info here ?

I think for normal cases we already reject the NULL format info. I am a
little worried that I might have missed some special case where that
might not hold. But I'm not sure what would be the best way to guard
against it. I really don't want to sprinkle NULL checks everywhere, and
in fact I didn't.

And by normal I mean the addfb/addfb2 ioctls. Those will go through
framebuffer_check() which does:

info = __drm_format_info(...)
if (!info) {
	...
	return -EINVAL;
}

Well, you should know since you write the code ;)

So the more special cases of internally created fbs is where the danger
lies I think.

I guess we could have drm_framebuffer_init() return a failure (also
maybe in the fb->dev!=dev case?). That would at least protect all the
uses after drm_framebuffer_init(). And I guess the uses before _init()
are somewhat of a special case, and up to each driver to make sure that
it knows what it's doing if it has uses like that.

The parentheses are not needed.

I think I had a bit of cocci to do that... Yeah, it's there, and rerunning
it does clean this up.

spatch is rather finicky and does occasionally miss entire files when
you run it in the -dir mode. But in this case it clearly do something to
the file, so not sure why the cleanup part didn't get done.

Not sure I can tell the tool that. Probably easier to remove it by hand
afterwards.

Added by cocci. I guess I can tell it to clean that up, but have to
double check that it won't accidentally clean up something else too
which needs extra parens.

I assume you mean fb->pixel_format.

You could also compare set->fb->format != set->crtc->primary->fb->format which 
should be slightly more efficient.

This is an interesting one :-) If fb->format is NULL you will crash, and if it 
isn't this is a no-op.

(randomly picking a driver for this comment)

As a candidate for another patch series, what would you think about storing 
format names in the format info structure, and getting rid of the 
drm_get_format_name() function ? It might increase the kernel size a bit 
though, but I don't think that's an issue.

You can write this

You should use fb->format->cpp[0]. Likewise for the other format information 
fields accessed in this driver.

Fine with me, you can create a follow-up patch that manually fixes the left-

[PATCH v2 31/32] 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.
