Currently only fast solid color clear performance is measured.
A large buffer is allocated and solid color clear operations
are executed on it with randomly chosen properties (position
and size of the region, clear color). Execution time is
measured and output together with the amount of pixels
processed.

The 'simple' variant only executes one G2D command buffer at
a time, while the 'multi' variant executes multiple ones. This
can be used to measure setup/exec overhead.

The test also serves a stability check. If clocks/voltages are
too high or low respectively, the test quickly reveals this.

Hi Tobias,

As most of this series is quite Exynos specific I will cover the misc
bits, and leave the core part to someone familiar with the hardware.

Might I suggest that we treat this (and your follow up utility) as a
test ? I.e. use

if HAVE_INSTALL_TESTS
bin_PROGRAMS = \
	exynos_fimg2d_perf
else
noinst_PROGRAMS = \
	exynos_fimg2d_perf
endif

and amend the block below appropriately ?

Can you add a licence to this file. Would be nice if it's covered by
X/MIT so that *BSD folk and others can use your tool.

I'm suspecting that having this as a runtime option will be better.
Something like ./exynos_fimg2d_perf --output mathematica ?

As a general note I would recommend keeping statements on separate lines
(none of if (foo) far()) as it makes debugging easier.

Although all of the above are my take on things, so checks with the
Exynos crew if they feel otherwise :-)

Cheers,
Emil

sure, honestly I don't even remember why I didn't add these as tests?
*confused*

Will do! Even though I probably won't go with a MIT license.

Well, I was thinking about removing the Mathematica specific code for
the submission, but I then left it in. I use Mathematica for parts of my
thesis, so it's usually my preferred tool to visualize data. I guess a
more 'open-source' friendly solution here would be to provide GnuPlot
output, but I guess I leave that to another use :)

OK, changing this.


With best wishes,
Tobias

Hello,

the new version should fix most of the mentioned issues.

Except for this, I didn't change it since I don't see the point. In fact
I think that splitting the few occurrences makes the code less readable.

I haven't worked with getopt before, so I gave it a try and made all
these hardcoded parameters configurable.

With best wishes,
Tobias

Beauty is in the eye of the beholder.

Nice :-)
