[igt-dev] [PATCH v6 00/13] chamelium: Test the plane formats

[igt-dev] [PATCH v6 00/13] chamelium: Test the plane formats

[Maxime Ripard]

Hi,

Here is another attempt at a serie that aims at starting to test the plane
formats using the Chamelium over the HDMI. This was tested using the vc4
DRM driver found on the RaspberryPi.

There's been a number of changes from the RFC thanks to the feedback from
Eric Anholt, Paul Kocialkowski and Ville Syrjälä.

The series now relies mostly on igt_fb, with some decoupling from cairo and
a bunch of new helpers to aim at being able to convert igt_fb to arbitrary
DRM formats. The list of formats have been extended a bit, but is quite
small at this point. We also rely solely on either pixman or the existing
format conversions functions at them moment, and we allow cairo surfaces to
be created for framebuffers in a format not supported by cairo, through an
intermediate conversion to RGB24.

However, since it's now abstracted away from the igt_fb users, we can
easily add some routines to convert to additional formats if needed. And
since the code was so close now, it's been integrated into kms_chamelium.

Let me know what you think,
Maxime

Changes from v5:
  * Fixed a typo

Changes from v4:
  * Added Eric's Reviewed-by
  * Dropped the preferred mode patch
  * Use the igt_fb pattern if we can
  * Rebased on top of master

Changes from v3:
  * Plug into the cairo surface conversion code, and share the code between
    the explicit conversion and the implicit one done when asking for a
    cairo surface for a framebuffer in a format not supported by Cairo.
  * Rebased on top of master

Changes from v2:
  * Reworded a commit log
  * Dropped commit making chamelium_calculate_fb_crc static
  * Added a few more missing formats
  * Changed PIXMAN_invalid to 0 to make sure it never conflicts with a
    pixman format

Changes from v1:
  * Add a README for the test lists
  * Add igt_fb buffer mapping / unmapping functions
  * Add igt_fb buffer format conversion function
  * Add pixman formats to the format descriptors
  * Made some refactoring to kms_chamelium to support format tests
  * Created sub-tests for the formats

[igt-dev] [PATCH v6 01/13] fb: Add buffer map/unmap functions

[Maxime Ripard]

The current code to manipulate the buffer has the assumption that we can
create an underlying cairo instance.

However, when it comes to supporting various formats, cairo is very limited
so we would need to decouple the buffer access from cairo surfaces.

Let's create a function that allows to map the underlying GEM buffer from
an igt_fb structure, which will then allow use to manipulate as we wish.

[igt-dev] [PATCH v6 02/13] fb: convert: Remove swizzle from the arguments

[Maxime Ripard]

Since it can be inferred from the framebuffer that is already given as an
argument, it is redundant and can be removed.

[igt-dev] [PATCH v6 03/13] fb: Create common function to convert frame formats

[Maxime Ripard]

The current code to convert between two buffer formats is quite tied to the
cairo surface infrastructure. Since we'll want to reuse it, make that
function more generic by introducing a common structure that passes all the
arguments and a common function that will call the right functions we
needed.

I guess we could yes. I'll try to adjust the patches to do that.

After looking into it again, now I remember why I didn't do what you
suggested. In the case where you are in the YUYV path, with a "shadow"
buffer being used to perform the cairo operations on top of an YUV
buffer, you end up with conversions in create_cairo_surface__convert
and destroy_cairo_surface__convert, getting a fb_convert_blit_upload
structure as an argument.

That structure however is used to convert one buffer to the shadow
buffer, or the other way around at destroy time. However, a single
igt_fb is allocated for that structure, which makes it impossible to
assign the second fb in that particular case. All the informations
needed to perform the conversion are stored in multiple structures
(fb_convert_blit_upload.linear, fb_convert_blit_upload.blit, and the
actual igt_fb instance) that we need to aggregate to find the correct
conversion parameters.

The patch series I mentioned before [1] changes fb_blit_linear to inherit
from igt_fb. So presumably that should help?

Yeah, except that the shadow buffer would still not have a backing
igt_fb, and we would need to assume that all the parameters for that
buffer are the same than for the source, including the offsets and
stride. This looks a bit fragile.

Ah, the rgb24 thing? Hmm. I guess we could make that into an igt_fb as
well.

[igt-dev] [PATCH v6 04/13] fb: Add format conversion routine

[Maxime Ripard]

The chamelium format subtests will need to convert the reference pattern to
the format to be tested on the DRM device.

However, Cairo is very limited when it comes to format, and while pixman
has much more support for formats, it's still falling short compared to
what DRM exposes, especially on the YUV side. Plus, since we want to run
CRC checks on the frame, we can't afford having conversions back and forth
between RGB24, as the current API is doing.

In order to abstract this away, let's create a function that will convert a
igt_fb structure to another DRM format and return the converted igt_fb.

For now, we will use only cairo to do the conversion, but we will use other
libraries or roll our own routines to convert to more exotic formats and
abstract it away from the users.

[igt-dev] [PATCH v6 05/13] fb: Fix ARGB8888 color depth

[Maxime Ripard]

The ARGB8888 has been listed as having a 32 bits depth, while it actually
is a 24 bits format. Fix this.

I think 32 is the more usual definition for this.

Isn't color depth about the color itself? I guess alpha wouldn't apply
in this case.

In the same format list:
  - RGB565 has a depth of 16
  - XRGB8888 has a depth of 24
  - XRGB2101010 has a depth of 30
  - ARGB8888 has a depth of 32

Which seems to indicate that the list indeed meant that the color
depth is about the color, and that ARGB8888 is wrong.

Not according to X at least.

  visual:
    visual id:    0x6d
    class:    TrueColor
    depth:    32 planes
    available colormap entries:    256 per subfield
    red, green, blue masks:    0xff0000, 0xff00, 0xff
    significant bits in color specification:    8 bits

Same for eg. drm_mode_legacy_fb_format().

None of those other things have alpha, so they are still
consistent with the depth==32 definition for ARGB888.

"24 bits almost always uses 8 bits of each of R, G, B. As of 2018
24-bit color depth is used by virtually every computer and phone
display and the vast majority of image storage formats. Almost all
cases where there are 32 bits per pixel mean that 24 are used for the
color, and the remaining 8 are the alpha channel or unused."

There's 32bpp, but the depth is 24 bits.

But maybe the X11 legacy says otherwise, I don't know. What's your
suggestion then? adding yet another field?

I need the actual color depth in order to check whether the conversion
from one format to another would lead to a lesser number of bits per
color, and as such should fall back to a more conservative
pattern. See the later patches in this series.

[igt-dev] [PATCH v6 06/13] fb: Add support for conversions through pixman

[Maxime Ripard]

Pixman allows for much more conversions than cairo, and we don't want to
open code conversions routine for the common formats.

Let's plug pixman in our conversion function so that we can benefit from it
when possible.

[igt-dev] [PATCH v6 08/13] fb: Add more formats

[Maxime Ripard]

We're going to need some DRM formats, and we're going to need the igt_fb
code to handle them. Since it relies on the format_desc structure to map
the DRM fourcc to the pixman and cairo formats, we need to add these new
formats to that structure.

[igt-dev] [PATCH v6 09/13] chamelium: Split CRC test function in two

[Maxime Ripard]

We have two use cases in our current sub-test suites: the tests that test
all the modes exposed by the driver, and the ones just picking up one.

Instead of having to deal with this two cases in the same function as it is
currently done, move the part that test a single mode into a separate
function, and just call it for every mode that we want to test if needs be.

This will result in a simpler function that will be easier to extend to
support formats.

[igt-dev] [PATCH v6 10/13] chamelium: Change our pattern for a custom one if needed

[Maxime Ripard]

The current pattern being used is the one generated through the
igt_create_color_pattern_fb.

However, in order to deal with multiple formats and the upsampling /
downsampling issues that might arise from converting back and forth between
formats, we will need to have a pattern with quite precise color values,
and without any shades or gradient of colors.

Let's create a function that will generate that pattern in the chamelium
code if we need to convert the framebuffer to a smaller depth, and use the
current pattern otherwise.

The easiest way to do that will be to only use values that would have the
same part on the common most significant bits (5, to deal with most
formats) and have the same bit repeated on the least significant bits that
are going to be dropped and / or padded when converting between formats.

Pixman will fill the lowest bits with 1, and our hardware (this has been
tested on a Raspberry Pi's VC4) is able to support that, so the easiest is
to just use all 1's for our components in order to still be able to compute
the CRCs.

[igt-dev] [PATCH v6 11/13] chamelium: Add format support

[Maxime Ripard]

In order to introduce CRC subtests for DRM formats, we need to take an
intermediate step.

The current code will generate a pattern in XR24, and will try to compare
the CRC returned by the Chamelium for each frames.

This CRC is computed on an XR24 format as well, so it works. However, as
soon as we will start implementing other formats, if we just change the
format of the pattern, the raw content of the buffer, and therefore the
CRC's won't match anymore.

In order to address that, we will need an intermediate step, and we will
now still create the XR24 pattern, and compute its CRC, then convert it to
the format we want to test, and finally retrieve the CRC from the Chamelium
to compare it with the one from the XR24 pattern.

The current code is converted to the new prototype that will take the
fourcc of the format to test, even though we're still using XR24 everywhere
for now.
