The swap interval function must be called on the same thread that
rendering takes place on. This fixes an issue where the turbo speed and
frame limiter hotkeys fail to disable vsync when the OpenGL renderer is
used.
Split code in 2 parts
* Base class (GSWndEGL) that implement the core EGL and GL context
* Derived class (GSWndEGL_X11/GSWndEGL_WL) that implement the backend to handle native resources
Note: Most backend code is only useful for GSopen1/PS1 mode. GSopen2 only requires
the AttachNativeWindow implementation
Code is based around EGL_EXT_platform extension that allow to select the platform at runtime.
Note: I think the extension was integrated in EGL 1.5
The X11 backend was mostly converted to XCB
The wayland backend is only a placeholder for future code
I don't know if MS windows is/could be supported with EGL_EXT_platform API
Code validated on Mesa. Proprietary drivers aren't yet tested.
* require a 3.1 context
* unattach texture of the fbo when they're not used
(avoid to have a texture and depth_stencil with different size)
Note: except minor shader bug it works on Nvidia 340.23.01
* Fix to create a 3.0 GLES context
* set a default precision to fix most of shader compilation issue
* Crash later because of GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT
=> need to test opensource driver
* 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
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5713 96395faa-99c1-11dd-bbfe-3dabce05a288
* clean extension management and fix compilation of previous gl44 code.
* Use pixel buffer object to upload texture data.
=> avoid crash on AMD driver
=> a bit faster and probably got some margins for the future
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5712 96395faa-99c1-11dd-bbfe-3dabce05a288
* uniform was wrongly set before the activation of the program (free driver only)
* Always use only 1 drawbuffer. Easier besides previous setup was wrong for convert:ps_main1
GLES trial (v3):
* add the cmake option GLES_API. Note library (libgles) are hardcoded for the moment
* Disable opengl check
* Disable gl_GetDebugMessageLogARB not supported!
* Emulate gl_DrawElementsBaseVertex, add manually the index offset (surely slow but work)
* Fix hundred of shader error (no implicit cast of integer to float...)
Unfortunately GLES doesn't support dual blending so no blend in hardware renderer. Otherwise it is fine
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5700 96395faa-99c1-11dd-bbfe-3dabce05a288
* try to setup advance gl context attribute. If driver doesn't support it fallback to the default.
zzogl:
* use glsl2h to generate an header shader as GSdx. Much easier to install
* Get GSUniformBufferOGL & GSVertexArrayOGL speed improvement from GSdx
cmake:
* detect current gcc version. Yield a warning if < 4.7 or an error if < 4.5
glsl2h:
* support zzogl too
* compute md5sum to avoid useless relink
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5696 96395faa-99c1-11dd-bbfe-3dabce05a288
* fix shader compilation on Nvidia (broken on r5682)
* fix various memory leak thanks to Valgrind
Cmake: fix a minor typo
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5688 96395faa-99c1-11dd-bbfe-3dabce05a288
* don't delete the wnd in GSclose. It can still be used later
* Properly detect the GL_ARB_gpu_shader5 extension for Fxaa
* A couple of fix in Create (GSopen1) of GSWndEGL/GSWndOGL
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5674 96395faa-99c1-11dd-bbfe-3dabce05a288
* add exception in GSWndEGL and GSWndOGL
* Try to use EGL when GLX failed => you don't need any flags for the opensource driver ;)
cmake: don't install anymore the glsl shader
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5671 96395faa-99c1-11dd-bbfe-3dabce05a288
gsdx:
* move gl function loading into GSwnd. Clean the header and avoid to rely on macro.
* Always require libegl for GSdx. You still need to select the API at compilation.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5670 96395faa-99c1-11dd-bbfe-3dabce05a288
* factorize sample object creation
* remember frame buffer attachment state
* Use a basic context on EGL. Allow to use Mesa 9.1 on AMD GPU.
* precompile vertex and geometry shader to avoid benchmark polution on replay
* Try harder to detect FGLRX driver on window
* various clean
Remain to fix the coordinate system for upscaling

* Fix shader alpha issue. Hoppefully fix lots of glitches.
* Use glBufferSubData to upload data into the constant buffer instead of map/unmap. More fps :)
* Fix wrong api setup on EGL
* Be more portable on glsl2h

* clean texture management & use different texture unit for various texture operation
* separate sampler and texture setup
* Always disable GL_SCISSOR_TEST before any cleaning to be sure the all pixels are reset
* properly set upscale_multiplier in the linux gui (was mixed with msaa). Unfortunately it is still broken...
* Fix EGL with GSopen1
* Use stdcall for function definition in the replay (avoid segmentation fault)
* Directly use gl_Position in shader instead of an extra user defined variable
git-svn-id: http://pcsx2.googlecode.com/svn/branches/gsdx-ogl-wnd@5648 96395faa-99c1-11dd-bbfe-3dabce05a288
* fix wrong interaction when both GL41 or GL42 aren't supported
* Add a new define to downgrade opengl requirement to test the free driver and EGL
=> As far as I can tell, they only miss geometry shader& GLSL150 (got GLSL140)
* Found a way to avoid crash in AMD driver. Skip the upload of small texture but rendering is wrong now...
git-svn-id: http://pcsx2.googlecode.com/svn/branches/gsdx-ogl-wnd@5643 96395faa-99c1-11dd-bbfe-3dabce05a288
* remove an old&useles dummy geometry shader (was used to workaround amd bug)
* use a basic X11 window for GSopen1
* redo the replayer: it is now based on dlopen rather than standard static/dynamic library. AMD driver doesn't play nicely with the later...

* initialize the context status variable that take care of some startup hang
* cmake: don't link and compile EGL when it isn't requested
git-svn-id: http://pcsx2.googlecode.com/svn/branches/gsdx-ogl-wnd@5528 96395faa-99c1-11dd-bbfe-3dabce05a288
* implement GSWndEGL copy/pasted from zzogl.
* remove linux debugging shader that failed to compile on window
* add additional debug message during context creation
