Lucas De Marchi 67967e9b5c exynos: annotate public functions
while read sym; do
	read f func line _ <<<$(cscope -d -L -1 $sym)
	if [ ! -z "$f" ]; then
		sed -i "${line}s/^/drm_public /" $f
	fi
done < /tmp/a.txt

In which /tmp/a.txt contains the public symbols from
exynos-symbol-check. The idea here will be to switch the default
visibility to hidden so we don't export symbols we shouldn't.

Inki Dae be40710f06 exynos: change the license to X11/MIT
Change GPL license of Exynos related code to X11/MIT.

I'd like to keep a consistent license across all Exynos code
because License checker notices two more licenses exist
in libdrm.

For the license change I need to get your agree - all committers.
So please give me Acked-by if you agree with me.

Tobias Jakobi 676462c43e exynos/fimg2d: add g2d_move
We already have g2d_copy() which implements G2D copy
operations from one buffer to another. However we can't
do a overlapping copy operation in one buffer.

Add g2d_move() which acts like the standard memmove()
and properly handles overlapping copies.

Tobias Jakobi 60df358196 exynos/fimg2d: add g2d_config_event
This enables us to pass command buffers to the kernel which
trigger an event on the DRM fd upon completion.
The final goal is to enable asynchronous operation of the
G2D engine, similar to async page flips.

Passing the event userdata pointer through the G2D context
was chosen to not change the current API (e.g. by adding
a userdata argument to each public functions).

Tobias Jakobi bf666b5e99 exynos/fimg2d: make g2d_add_cmd() less heavy
The function currently checks for each added command
if an overflow of the corresponding command buffers
occurs, but none of the callers ever checks the
return value.

Since all callers are now converted to use
g2d_check_space() simplify the function.

(1) The overflow checks become asserts, so they're only
    active for debug builds. This is fine since
    g2d_add_cmd() is not part of the public API.

(2) Switch the return value to void.

(3) Explicitly state that the caller has to check
    buffer space before calling g2d_add_cmd().

Tobias Jakobi e3c97d1a24 exynos/fimg2d: add g2d_validate_xyz() functions
The G2D headers define a number of modes through enums
(like e.g. color, select, repeat, etc.).

This introduces g2d_validate_select_mode() and
g2d_validate_blending_op() which validate a
select mode or blending operation respectively.

Use this together with g2d_check_space() in
g2d_{blend,scale_and_blend}().

For this we move parameter validation to the top and
also validate the select mode of the source image and
the requested blending operation before starting
command submission.

Tobias Jakobi 2362c88251 exynos/fimg2d: add g2d_check_space()

enough space left prior to actual submission of the commands.

Use this in g2d_{solid_fill,copy,copy_with_scale}().

For this the parameter validation before buffer space

Also don't reset the G2D context in this situation since
the buffers are not partially submitted anymore.

The repeat mode in g2d_copy_with_scale() is checked first
to make computation of space easier.

Tobias Jakobi 89037326ca exynos: honor the repeat mode in g2d_copy_with_scale
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.

Inki Dae bbf6e3dea3 libdrm/exynos: add test application for 2d gpu.
This patch adds library and test application for g2d gpu(fimg2d).

The fimg2d hardware is a 2D graphics accelerator(G2D) that
supports Bit Block Transfer(BitBLT).

The library includes the following primitive drawing operations:
.solid fill - This operation fills the given buffer with
	the given color data.
.copy - This operation copies contents in source buffer to
	destination buffer.
.copy_with_scale - This operation copies contents in source buffer
	to destination buffer scaling up or down properly.
.blend - This operation blends contents in source buffer with
	the ones in destination buffer.

And the above operations uses gem handle or user space address
allocated by malloc() as source or destination buffer.

And the test application includes just simple primitive drawing
tests with the above library.
And the guide to test is as the following,
	"#exynos_fimg2d_test -s connector_id@crtc_id:mode"

With this above simple command, four primitive drawing operations
would be called step by step and also rendered on the output device
to the given connector and crtc id.
