Gregory Hainaut 77f9113301 gsdx-gl: use CONTEXT_FLAG_NO_ERROR_BIT_KHR to reduce driver overheard 
Didn't test it yet as my driver is too old.

Note: might break the open source drivers.

Gregory Hainaut 9ba949c2d9 gsdx-debug: support correct logging on mesa 
By default low severity message were disabled. (thanks to be open source)

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.

refractionpcsx2 179a4cead5 GSdx: Fix compilation 2015-10-18 02:01:56 +01:00
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 3145031c05 gsdx-ogl: add glBindBufferRange function pointer 2015-08-15 20:06:34 +02:00
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 ;)
 2015-08-08 09:16:49 +02:00
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
 2015-07-17 21:08:49 +02:00
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 6ed137dc9c gsdx-ogl: log openGL driver version 2015-07-13 12:35:55 +02:00
Gregory Hainaut f3c0c1bb88 gsdx-ogl: TexParamami is provided in core 2015-06-25 10:25:57 +02:00
Gregory Hainaut 8393ba56d6 gsdx-ogl: rework palette texture handling 
Redirect the red channel to alpha channel for 8 bits texture.

It avoid special management in the shader
 2015-06-24 19:50:09 +02:00
Gregory Hainaut 237ffcf796 gsdx-ogl: Make GL_ARB_draw_buffers_blend optinal for limited DX10 drivers 2015-06-10 22:55:27 +02:00
Gregory Hainaut a1bfb237e6 Partially Revert "gsdx-ogl: drop support of GL_ARB_clear_texture extension" 
This reverts commit 03e72781aa.

Let's add back the clean texture pointer

I want to test it on
1/ DSA
2/ MT driver
 2015-05-16 00:31:25 +02:00
Gregory Hainaut d6448183d7 gsdx-ogl-debug: insert error message in GL stream 
This way, you can see your message in the GL debugger
 2015-05-08 00:16:31 +02:00
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 :)
 2015-05-06 19:09:13 +02:00
Gregory Hainaut b1ec8a5a42 gsdx-ogl: detect support of GL_EXT_texture_filter_anisotropic 2015-05-02 10:53:19 +02:00
Gregory Hainaut 335695bd0e purge GLES from GSdx ! 
mobile will use vulkan (or any new API) anyway
 2015-05-01 20:02:17 +02:00
Gregory Hainaut 757726bb91 gsdx-ogl: allow to invalidate the texture 
It just a hint to the driver to avoid any useless transfer

I don't expect any change but it is free so why not ;)
 2015-04-25 12:50:12 +02:00
Gregory Hainaut 75817bb27b gsdx-ogl: add a quick and dirty DSA layer emulation 
The global idea is to use
1/ bind in tight loop
2/ DSA otherwise (to avoid any binding in tight loop)
 2015-04-25 12:50:11 +02:00
Gregory Hainaut eb257d9295 gsdx-ogl: add dsa function place holder 2015-04-25 12:50:11 +02:00
Gregory Hainaut baf84b98c4 gsdx-ogl: add override_GL_ARB_texture_barrier option 
To ease regression test.
 2015-04-25 09:59:25 +02:00
Gregory Hainaut b12eb45bb7 gsdx-ogl: try to avoid crash on fglrx windows 2015-04-25 09:50:19 +02:00
Gregory Hainaut f71eb171cf gsdx-ogl: add glTextureBarrier function pointer 
Could be useful
 2015-04-24 18:35:01 +02:00
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 e73d8f383b gsdx-ogl: compilation fix for old distribution 2014-11-11 15:01:22 +01:00
Gregory Hainaut a573ce185c gsdx-ogl: mark GL_EXT_shader_io_blocks as mandatory for GLES 2014-10-02 20:44:22 +02:00
Gregory Hainaut d37cc8e1e7 gsdx-ogl: GL_ARB_shading_language_420pack is now mandatory 
All API/drivers support it so time to remove the fallback.
 2014-10-02 20:44:22 +02:00
Gregory Hainaut f46e8cc6ac gsdx-ogl: bump base requirement to 3.3 
A couple of fallbacks were introduced for the Mesa driver that only support 3.0
DSA will require a recent Mesa which already support GL3.3

Require at least SandyBridge for Intel GPU
 2014-09-30 22:18:20 +02:00
Gregory Hainaut 594f6c33a2 gsdx-ogl-ES: require GL_EXT_shader_io_blocks + GLES3.1 
Allow to use same shader interface for all API

Note: on the GL API it will require GL3.3 (see next commit)
 2014-09-30 22:18:01 +02:00
Gregory Hainaut 8833afc2fa gsdx-ogl: drop GL_ARB_multi_bind 
It will be replaced by DSA so let's reduce the complexity of opengl
 2014-09-28 12:23:44 +02:00
Gregory Hainaut 1e86e3cb08 gsdx-ogl: rework callback debug 
* use DebugOutputToFile as a callback of gl error. Add a breakpoint to
  find the culprit GL call
* use string instead of char[n]

Note: CheckDebugLog is potentially useless now
 2014-09-28 12:00:34 +02:00
Gregory Hainaut 9d8d702aa6 gsdx-ogl: drop GL_NV_depth_clamp extension 
superseeded by GL_ARB_clip_control
 2014-09-28 12:00:34 +02:00
Gregory Hainaut d720cc16a6 gsdx-ogl: gl4.5: add plumbering to support direct_state_access and clip_control 2014-09-28 12:00:33 +02:00
Gregory Hainaut b020bd76c6 gsdx-ogl: restore gles build 
Add the --gles build option to the linux main script
Ifdef all gl code not supported on gles3 (note some will be reenabled for gles3.1)

Note: it probably doesn't run anymore. My Nvidia driver doesn't support
yet egl/gles so I can't test it. Feel free to contribute.
 2014-03-29 11:55:02 +01:00
Gregory Hainaut 483b5a75e8 gsdx ogl: automatic setup of geometry shader 
* disable it for gallium Mesa driver
* Re-enable it for Nvidia driver
