[igt-dev] [PATCH i-g-t 1/4] lib/igt_fb: Fix the pixman converter

[Ville Syrjala]

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

Cairo doesn't do RGB888. The shadow buffer must be in XRGB888 (which
is what our YUV converters also assume). We did calculate the shadow
stride/size with four bytes per pixel, but we just put the wrong
format in the fb metadata.

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

Add more asserts to make sure the converted formats are
correct.

[igt-dev] [PATCH i-g-t 3/4] lib/igt_fb: Use linear.fb in the converter

[Ville Syrjala]

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

The converter operates between the linear and shadow fbs. When using
the blitter path there is no particular reason to assume that the
linear fb and actual fb have the same strides for instance. Thus
consulting the actual fb for metadata is not really correct.

We can also simplify the mmap() path by copying all the original
fb metadata into linear.fb as there we map the original fb directly.
We just have to keep clearing linear.fb.gem_handle so that the
dtor knows which kind of beast it's got.

[igt-dev] [PATCH i-g-t 4/4] lib/igt_fb: Generalize the slow read from gtt mmap handling

[Ville Syrjala]

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

Make the handling of slow gtt mmap reads generic, and extend it to
the pixman converter. Makes the pixman path a bit faster.

With testing just XRGB8888 and XBGR8888 on KBL:
$ time kms_plane --r pixel-format-pipe-A-planes
- real	0m18,757s
+ real	0m2,635s

The other choice being igt_assert(buf) or igt_xmalloc() :)

I figured the NULL ptr explosion is as good as an assert. But
since it's trivial to handle it gracefully let's do that.

[igt-dev] [PATCH i-g-t v2 4/4] lib/igt_fb: Generalize the slow read from gtt mmap handling

[Ville Syrjala]

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

Make the handling of slow gtt mmap reads generic, and extend it to
the pixman converter. Makes the pixman path a bit faster.

With testing just XRGB8888 and XBGR8888 on KBL:
$ time kms_plane --r pixel-format-pipe-A-planes
- real	0m18,757s
+ real	0m2,635s

v2: Use the original src buffer if the malloc fails (Chris)
    Drop the duplicated comment about things being slow

I already had a similar fix to 1/4 in my tree but didn't send it out yet. :)

I'm curious, how did you find that issue in the first place?

It went through CI and I could run the kms_plane tests on my test
laptop, so I'm confused.

XBGR8888 fb contents were gibberish. Since you disabled that
format in kms_plane we don't normally see the problem at all.

Unfortunately this doesn't fix the XBGR8888 crc fail. That one looks to
be some odd hardware issue as it still fails even if I change the LUT
programming to keep only the single msb. The colors on the screen do
look reasonably correct, and the fb data looked correct (apart from
0 vs. 0xff alpha, but manually changing that didn't make a different
either). So for now this remains a mystery :(

I have some patches internally that converted color encodings and used cvt->dst/src.fb->drm_format. It failed with the RG24 there.

Took a bit to figure it out. :)
