[igt-dev] [PATCH v3 0/8] Test cases for fbdev

[igt-dev] [PATCH v3 0/8] Test cases for fbdev

[Thomas Zimmermann]

This patchset adds read and write tests for fbdev. It compares the content
of the framebuffer and reference buffer. A number of the special cases
near the EOF are also tested.

Depending on the implementation (sys, cfb), fbdev read/write changes its
semantics. Together with a kernel patches [1] these test cases intend to
provide a reference.

v3:
	* put igt_describe() before the block it describes (Petri)
v2:
	* move tests into subtest groups
	* do setup in igt_fixtures (Daniel, Chris, Petri)
	* add additional tests for unaligned access and NULL-pointer
	  buffers (Daniel)

Move the existing tests into subgroups for testing modesetting and
accessing the framebuffer.

[igt-dev] [PATCH v3 2/8] tests/fbdev: Map framebuffer in igt_fixture

[Thomas Zimmermann]

The mapping of the framebuffer memory will be useful for read/write
tests. Move it into an igt_fixture block.

After this patch, map is assigned to in an igt_fixture and read in a
subtest. As igt_fixture uses longjmp(), the value of map when read
depends on whether this is compiled with or without optimizations.

The options for such variables are:

1) move it to global scope
2) make it volatile
3) make a struct data_d with the map (and in a later patch, buf as
   well) variable and assign its members instead.

I think we prefer 3 generally.

One thing I wondered about is that the tests are build with
-Wno-clobbered. What's the reason? I'd expect that the compiler would
have warned about this problem.

I would have used 2. What's the benefit of of using 3?

Too many warnings already accumulated mostly, some of them false
positives.

Actually I take that back, it's an established convention when you
pass data to functions, not so much in code like in your series where
the stuff is entirely contained within the function.

That leaves no benefits so option 2 looks real juicy here indeed.

igt_require here instead. The thumb rule is igt_assert for checks
where failure says "kernel is broken", igt_require where failure says
"cannot test this".

Here, these igt_requires should be igt_asserts.

Make sure fix_info has good values here in the case where we didn't
execute any subtests in framebuffer_tests(). If I read right it's
initialized in the igt_fixture so it should be good...

Too small to test, or should it always be larger?

These igt_requires should be igt_asserts.

[igt-dev] [PATCH v3 5/8] tests/fbdev: Add tests for write operations on framebuffer

[Thomas Zimmermann]

The write tests check the written buffer against the content of the mapped
framebuffer.

Same question here about framebuffer size as in that one earlier patch.

[igt-dev] [PATCH v3 7/8] tests/fbdev: Add tests for accessing framebuffer near EOF

[Thomas Zimmermann]

Fbdev has some specific behavior when reading/writing near the EOF, which
the eof test checks. If at least one bytes has been written, the number
of bytes has to be returned, otherwise an error code (if any) has to be
returned, or otherwise 0 has to returned. Not all drivers get this right.

	* put igt_describe() before igt_subtest() (Petri)

Yeah, tests/intel-ci/fast-feedback.testlist. For getting this series
fully tested, add a patch to the series that removes the line

igt@fbdev@mmap

from that file, with subjectprefix "CI" or "HAX" so it's clear it's
not the final patch to be committed.

The read/write contents verification should work well for BAT; quick and
cover the simple use cases we know people do run into. Unaligned and
negative tests are better suited to full test run since they should not
provide any deep probes into the driver (and so not as likely to catch
unexpected bugs in future patches).
