Hello,
I will fix it.
Thanks for review.
Regards,
Andrii.

Re: [Piglit] [PATCH v2] miptree: test ability to use upside down miptree
Hi Andrii,
Pardon for joining so late. The patch looks ok, although a few bits I'm unsure
about - see the "Note" below.
There's a bunch of cosmetic suggestions as well - I won't read too much into
them though.

Then swap nlevels with LEVELS throughout the file.
static const GLubyte fancy_pixel = [255, 128, 64, 32];

Note: The variable "pos" is always 0. If that's intentional - I'd just
drop and simplify.

Use fancy_pixel for expected[]

Note: In piglit we try to run all the tests, even if one fails. Some tests could
be doing it wrong though :-(
Personally I would drop the "&& pass" from the loop condition and use:
pass = foo() && pass;

for (i = 0; i < TH; i++)
for (j = 0; j < TW; j++)
img[i][j] = fancy_pixel;
[snip]

With the LEVELS, all the above becomes:
for (i = 0; i < LEVELS; i++) {
glTexImage2D(GL_TEXTURE_2D, nlevels - 1 - i, GL_RGBA, w, h, 0,
GL_RGBA, GL_UNSIGNED_BYTE, img);
w /= 2;
h /= 2;
}

Re: [Piglit] [PATCH v2] miptree: test ability to use upside down miptree
It's preferable to push piglit tests first, and produce the CI test failure. CI staff will track the failure, and attribute it to the piglit patch. When the subsequent mesa patch is pushed, we track the resolution. The process gives us artifacts in git that help to analyze driver differences between stable releases. -Mark andrey simiklit writes: > Hello, > > If this patch is acceptable by everybody then > I guess that we need to push the following mesa patch before this one > to avoid errors from Intel CI because the fix for an issue which is tested > by this test is still there. > > https://patchwork.freedesktop.org/patch/254397/ > One of the last comment from Kenneth Graunke : > >>". >> So, back to Reviewed-by.

Re: [Piglit] [PATCH v2] miptree: test ability to use upside down miptree
Hello,
If this patch is acceptable by everybody then
I guess that we need to push the following mesa patch before this one
to avoid errors from Intel CI because the fix for an issue which is tested
by this test is still there.
https://patchwork.freedesktop.org/patch/254397/

[Piglit] [PATCH v2] miptree: test ability to use upside down miptree
From: Andrii Simiklit
Test that usage of upside down miptree doesn't cause assertion
The miptree:
level 0 = 1x1
level 1 = 2x2
level 2 = 4x4
...
level n = NxN
should be acceptable for case when we don't use a min filter.
v2: - Unnecessary function calls were removed
- The 'glClearColor' call was moved to 'piglit_display' function
- The program creation was moved to 'piglit_init' function
- The requirements check was moved to 'piglit_init' function
( Erik Faye-Lund )
- Fixed a leak of texture which is created in 'setup_texture'
