This makes it easier to spot memory corruptions which don't become
visible when using a plain buffer filled with a solid color (so
corruptions that are just a permutation of the bytes in the buffer).

This also avoids the floating point conversion steps and just
uses pure integer arithmetic.
Since the G2D hardware scaling approach is a bit unintuitive,
document it in the function as well.
v2: Explicitly mention the normalization constant.

This is a combination of g2d_copy_with_scale and g2d_scale.
It is a pretty common operation to scale one buffer and then
blend it on top of another, so provide a direct way to that
operation.

Currently getchar() is used to pause execution after each test.
The user isn't informed if one is supposed to do anything for
the tests to continue, so print a simple message to make this
more clear.

If interested you can compact this as
printf("press <ENTER> to %s\n", last ? "exit test application" :
"skip to next test");

We have this and a ton of other neat helpers in igt. As I've probably said
countless times on irc and at conferences if someone bothers to make the
core of igt i915-agnostic (just needs changes in the function to open the
drm dev mostly) I'd love to see igt converted into a generic drm
testsuite.
And similar to piglit I think it makes more sense to have that outside of
any userspace components we ship to users, i.e. not in libdrm.
But I really can't justify doing this work to my dear employer ;-)
Cheers, Daniel

This is useful when the default repeat mode, which is 'repeat'
produces artifacts at the borders of the copied image.
Choose the 'pad' mode to make use of the color of the destination
image.
In my usage case the destination is the framebuffer, which is
solid filled with a background color. Scaling with 'pad' mode
would then just do the right thing and also produces nice
borders on the output.

In almost all functions the base address register is written, so it
makes sense to have a helper function for this.

Keeps the code cleaner, since the structs have to be initialized

The reason for this change is to let userspace use the header.
Currently 'make install' does not install it.

Hi Tobias,
Afaict that this was done intentionally. I believe the Samsung guys got
this out only to fulfil the "no drm(render) driver without open
userspace" policy.
Although it's nice to see actual user(s) (outside of libdrm) perhaps the
header could be cleaned up (#define TRUE 0, #define FALSE -1) a bit
before that ?
Either way it's up-to the Samsung/Exynos people to make the call.
Cheers
Emil

The coefficient mode enables use of global color, not alpha.

Hi Tobias,
Imho these are some nice cleanups. I believe that the Samsung/Exynos
people need to comment on the device specific ones, but I've checked
2-4, 6, 8, 10, 13-15 and they are quite ok (baring a trivial comment)
