Gregory Hainaut f99882c61c gsdx-ogl: keep gl_ActiveTexture & gl_BlendColor (fix MS compilation)
It seems openGL ABI isn't exactly the same between Windows and my PC.

Gregory Hainaut 0958b9db8e gsdx-ogl: use the standard openGL name
Function pointer was mangled to avoid any collision. Nowadays all symbols
are hidden so no risk of collision.

Syntax is nicer beside it would allow to put back GLES3.2. I think it
supports most of the used extension.

glActiveTexture & glBlendColor are provided without symbol query.

Gregory Hainaut b17803bb34 gsdx-ogl: wipeout of GL_ARB_bindless_texture
Code is completely broken. It doesn't help to improve speed.

Remove 200 lines ;)

Gregory Hainaut b4c04ed00a gsdx-ogl: wipeout subroutine code
Code was completey bitrotten
Code was a partial test (and yet 500 lines already)
Shader is more and more complex and multithreading support greatly
reduce the cost of shader switch

Gregory Hainaut e245b27c97 gsdx-ogl-debug: allow to dump various ps shader
Nvidia allows to get the ASM of the shader of the compiled shader. It is useful
to check the performance.

It also allow me to compile most of shader code path for QA

Dump is enabled in linux replayer + debug_glsl_shader = 2

Gregory Hainaut a1bfb237e6 Partially Revert "gsdx-ogl: drop support of GL_ARB_clear_texture extension"

I want to test it on

2/ MT driver

Gregory Hainaut 6d31124d3a gsdx-debug: only enabled advance gl debugging on linux
It will avoid some crash on windows for driver that doesn't support
the extension.

Make debug support mandatory for debug build on linux.

Gregory Hainaut cc4713d379 gsdx-debug: extend ogl debug capabilities
Group opengl calls into a nice name.

Apitrace shows them in a tree format that support folding. Previously it
was a long flat list (10K-40K of lines by frame)

I align the call number with the internal s_n variable. This way it is
easy to map GSdx dump output with the GL debugger :)

Gregory Hainaut 03e72781aa gsdx-ogl: drop support of GL_ARB_clear_texture extension
Extension is a bit slower.

We use it to clear the RT but we generally use it right away so
we don't avoid the FB attachment.

Gregory Hainaut 1e86e3cb08 gsdx-ogl: rework callback debug
* use DebugOutputToFile as a callback of gl error. Add a breakpoint to

gregory.hainaut 84895eadd9 gsdx ogl: correct most of Z-depth issue
Best setting if you driver support GL_NV_depth_buffer_float => GL_NV_Depth = 1 & logz = 0
Otherwise => GL_NV_Depth = 0 & logz = 1

Explanation of the bug:
Dx z position ranges from 0.0f to 1.0f (FS ranges 0.0f to 1.0f)
GL z Position ranges from -1.0f to 1.0f (FS ranges 0.0f to 1.0f)

Why it sucks:
GS small depth value will be "mapped" to -1.0f. In others all small values will be 1.0f! Terrible lost
of accuraccy.

The GL_NV_depth_buffer_float extension allow to set the near plane as -1.0f.
So
"GL z Position ranges from -1.0f to 1.0f (FS ranges 0.0f to 1.0f)"
will become
"GL z Position ranges from -1.0f to 1.0f (FS ranges -1.0f to 1.0f)"
and therefore
"z posision [0.0f;1.0f] will map to FS [0.0f;1.0f]" as DX

Yes we just get back all precision lost previously :)
However you need hardware (intel?) and driver support (free driver?/gles?) :(

gregory.hainaut e80b002929 gsdx ogl: Flush various pending work
* try to use more subroutine on VS&PS, unfortunately hit a driver crash!
* Call Attach/DetachContext through GSDevice so I can unmap currently mapped buffer
* Implement glsl part of GL_ARB_bindless texture, again hit another driver crash!
* various fix of GL_ARB_buffer_storage. Basic benchmark show only improvement on 'cold' case, I guess it will improve smoothness
* try to fix GL_clear_texture, no success so far. It seem the extension is limited to basic texture (aka no depth/stencil)

gregory.hainaut 07605941ef gsdx ogl:
* some preliminary work to test/benchmark bindless texture in the future (glsl was not yet updated)
Bindless texture allow to get a GPU texture pointer and then set it directly
to the shader as a basic uniform.
=> no more texture unit selection/validation
=> no more texture validation neither texture hash lookup

3rdparty: update gl header to the latest gl4.4

gregory.hainaut 0f603a98d5 gsdx ogl: Test the ARB_shader_subroutine GL4.0 extension
The idea was to replace shader program swith by pointer function calls inside
shaders.  At least parameters that are often changed between draw call. So far
I only ported atst and colclip. Unfortunately code is "slower" (on GSdx standalone).
For the moment keep the code but disabled.

If I understand well the validation of program is done in the "driver thread"
but the additional call are done in the overloaded MTGS thread. Apitrace
profiling shows faster GPU draw calls. Another possibility is that the driver still
need to validate the draw call because of others state change.

Here some stats on colin3 (90 frames):
without subroutine: UseProgram 125246
with subroutine: UseProgram 2906, subroutine 125945 => 3605 extra calls overhead (not
all parameters are ported to subroutine)

gregory.hainaut a46b489a24 gsdx ogl: various minor optimization.
* move most of gl states into a separate namespace. Extend it to depth/stencil/blend micro state
=> save 10,000 opengl call by frame for colin mcrae 3
* Only setup blend state of first drawbuffer
* Don't request anymore a debug context on dev/release build

* preliminary work for GL4.4 extensions (ARB_clear_texture & ARB_multi_bind). Disabled until I got a 4.4 driver
Note: I plan also to use ARB_buffer_storage
* compute texture gl option in the constructor (avoid a couple of swith case)
* redo texture unit management. Unit 0-2 for shaders, Unit 3 for texture operations. MultiBind will allow to bind 
shader input without disturbing texture binding points.

 + Detection of good/bad samples is based on primitive ID variable. However I'm not sure

 work
