[PATCH v2 0/7] Add Y-tiling support into IGTs

[Praveen Paneri]

This series adds Y-tiled buffer creation support into IGT libraries and
goes on to use this capability to add support into FBC tests to use
Y-tiled buffers.

[PATCH v2 1/7] lib/igt_fb: Let others use igt_get_fb_tile_size

[Praveen Paneri]

This function can be used by igt_draw to get accurate
tile dimensions for all tile formats.

v2: Added comments to function igt_get_fb_tile_size (Daniel)

Bits, not bytes.

I think this is in bytes, not pixels.


> + * @height_ret: Height of the tile in pixels

I think saying "lines" instead of pixels would be more appropriate
here.


Oh, and since we're already going to have to change some other things,
here's an OCD bikeshed: the rest of the file seems to use:
 * @param: description
instead of:
 * @param: Description
so you may opt to use the current standard.

A modifier constant.

Besides this, the patch looks good.

[PATCH] lib/igt_draw: Add Y-tiling support

[Praveen Paneri]

This patch adds Y-tiling support for igt_draw_rect function.

v2: Use helper function to get tile sizes (Ville)

v3: Moved igt_get_fb_tile_size() out of the for loop
 for better performance (Paulo)

For some reason I thought this series was using my original patch, but
I realized it's not:

https://patchwork.freedesktop.org/patch/72039/

Now that I read our past emails, I wonder that maybe I didn't send you
this specific patch of that series. I'm sorry for that. Obviously I'm
biased towards my version. Which one do you think is better? Would you
be willing to give my version a r-b, in case you think it's better?

Thanks,
Paulo

My MI-fu is not very strong, but I tried to check this against BSpec
and I believe this patch is correct. I also tested it, and it
definitely solves the problems with the BLT operations on Y tiling.

There's only a minor nitpick with a line going beyond 80 columns, but I
can fix that while applying.

[PATCH v2 5/7] tests/kms_draw_crc: add support for Y tiling

[Praveen Paneri]

From: Paulo Zanoni <paulo.r.zanoni@intel.com>

This is the program that's supposed to test lib/igt_draw. We just
added Y tiling support for the library, so add the tests now.

This is not my original version of the patch, yet there's no changelog
mentioning that this is a new version.

https://patchwork.freedesktop.org/patch/72040/

Why were the kmstest_unset_all_crtcs() calls added? My guess is that
they ended up here as a rebase artifact, but please clarify if there's
an actual reason.

[PATCH v2 6/7] igt/kms_frontbuffer_tracking: Add Y-tiling support

[Praveen Paneri]

Allow tests to create Y-tiled bufferes using a separate
argument to the test without increasing the number of
subtests.

v2: Changed tiling option to string (Paulo)

Re: [PATCH v2 6/7] igt/kms_frontbuffer_tracking: Add Y-tiling support

I had some minor nitpicks for this patch: reshuffling parameters
between lines and the way we handle the new argument and its help
message. Instead of requesting those trivial changes and creating yet
another review round-trip I just went ahead and implemented them as v3.
I hope you're fine with this approach. The patch can be applied without
the rest of the patches in the series, so I applied it & pushed to IGT
with my nitpicks and R-B.

[PATCH v2 7/7] igt/kms_fbc_crc.c : Add Y-tile tests

[Praveen Paneri]

Now that we have support for Y-tiled buffers, add another
iteration of tests for Y-tiled buffers.

Have you tested this on platforms that don't support Y-tiled buffers? I
don't see a check for that, so I wonder if we'll just fail some
assertion or correctly hit some igt_skip() call I couldn't find.

More below.

What I don't understand is why this part of the code chooses to go with
the tiling constants (I915_TILING_) only to later convert them to
modifiers with igt_fb_tiling_to_mod(). If this loop iterated over the
modifiers directly we wouldn't need that. The rest of the code only
cares about the modifiers.

This change is not keeping the indentation style, things should be
aligned with the parens (although I see they're actually aligned with
the quote, which is also weird). The same can be said for the other two
igt_info() calls in this patch.

This one is missing the "%s-tiled" part that was added in the other two
messages.

And we can probably create a "const char *tiling_name" variable to
store the %s part in order to avoid the same ternary operator in the 3
if statements.

I chose to loop over tiling constants as they are in a simple arithmetic 
order. anyhow I will just change that.

Also as mentioned above can I just add a check to skip Y-tiling tests 
for older platforms?

igt_skip_on(intel_gen(intel_get_drm_devid(drm_fd)) < 9 &&
                                tiling == I915_TILING_Y);

Just put the two local_format stuff in an array and iterate over it.

You can't do this here because the same subtest tests X tiling.

Perhaps we could make Y tiling be a separate subtest? I'm not a huge
fan of single tests that do tons of stuff.

Okay! what if I just skip the loop for Y tiling with some message?

Will it be possible in just one subtest. I thought we will have to 
duplicate all the subtests for Y-tile case? Plz suggest

The problem I reported before still happens to me. Please fix it before
resending.

I tried reproducing it on SKL. For me the test was just running fine.

I ran it in shell mode on ubuntu running the latest kernel.

Could you plz give some hint to repro it at my end.
Thanks,

How much time did each subtest take to complete? I have tests that
should take 1s but take up to 150s with the patch.

It was not taking 150s for me but some tests were taking around 7-8 
secs. I realized that call to igt_get_fb_tile_size() was happening 
inside a busy loop.
I have fixed the issue and I see most of the tests completing within a 
sec now. I have floated the updated patch and here is the link to new 
series. Plz review.
