Dear all,
I attached a patch of evas_gl_shader.
I've removed a comment which is creating dummy shader when using GL_OES_get_program_binary extension.
Mr. Haegeun Park who is in charge of GPU driver fixed get_program_binary bug in the SGX driver.
There's no need to create dummy shaders any longer.
And I've added link status checking code to validate the binary object.
Please review this patch.
Thanks.

Subject: [E-devel] [Patch] Evas gl shader use binary shader
I make patch related with evas gl binary shader.
The concept of binary shader is compile shader only once.
Some people want to use binary shader because of performance issue.
In current evas gl engine, every application have to compile shader each
time.
But I modify code , so only first running application need compile shader.
Other application use already compiled shader(binary shader)
The binary shader is made under HOME/.evas/gl_common_shaders directory.
Binary shader is created according to GL vendor,GL renderer, GL version and
Module_arch.
The basic flow is
1. First running application which use gl engine check binary shader
directory, but it can't find binary shader.
2. After compiling shader, It saves compiled shaders..
3. Other application checks shader directory, it can use binary
shaders.
In mobile target, using binary shader, I can save 150ms. (that time, there
is 11 shaders).
If there is more shaders and more applications, this flow maybe save more
total time.
(the above is now in, changelog coming, with change to using ~/.cache,
some formatting fixes, make ity do the desktop gl one right with the
retrievable hint parameter ont he program etc. - doesn't break desktop
gl at least. yay. a,so fixes to mke it compile at all).

More work, proudly supported by Samsung. Filters!
So now you can apply a whole host of cheesy visual effects to objects at
runtime. This is the first commit, there are a couple of more to come as I
tweak the filters, and fix blur with GL[1].
Please direct bugs to me nash@nash.id.au.
[1] You'd think shaders would be good at this.. but no, generic blur and GL
are like trying to get an apple product to work with Linux.

* log domains in lower-case only please. let's make it a standard so
we don't have to look at the code everytime to figure out the name...
* logs do NOT require trailing newline (\n), it's automatic!
* do NOT add newline inside log messages!
* add gl_common logging.
NOTE: I tried to compile all modules, but there are clear broken
modules such as cairo and qtopia. Other modules like gl_sdl are
broken as they were not updated to new gl_common api (resize
method AFAIR).

Subject: Evas evas_gl_shader.c patch
Patch for evas_gl_shader.c, need to check shader compile
errors too, not only program linking errors.
Not that it's very useful now since all Evas' shaders are in
good shape already, but it was useful when we're mucking around with
things.
And also to make Robi happy that there are some FST
contributions to E ;) And probably more to come...

work. (in ello) elementary stuff seems... less happy. will work on it! also
havent done the gles bits. just desktop gl (first port of call for
doing/testing). the #ifdefs are ther waiting with fixme's
SVN revision: 43653
that dont have runtime compilers using offline tools. binary blobs will need
to be provided in src trees as the shader_type_bin_target.h files
