Gregory Hainaut cdb71101a1 gsdx ogl: As Intel is too cheap to provide GL_ARB_direct_state_access on theirs expensive iGPUs 
Add a "slower" emulation of the extension...

Hopefully it will allow to start openGL on haswell (maybe broadwell) and later.

Gregory Hainaut d8050634f6 gsdx ogl: plug GL_NVX_gpu_memory_info and GL_ATI_meminfo 
to query available memory on the GPU

Requirement
* dedicated GPU (ofc!)
* proprietary driver. Free driver supports r600, radeonsi

Gregory Hainaut 179681ef18 gsdx ogl: enable AMD driver blending workaround only on latest legacy driver 
Legacy GPU:
Older driver will be broken.

Still supported GPU:
Please upgrade to the latest AMD driver 16.5.2 or 16.5.3 (and prey that future driver will still work)

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 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
 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

Redirect the red channel to alpha channel for 8 bits texture.

It avoid special management in the shader

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

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 :)

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)

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.
