Initially we copy pitch by line in the PBO and tell the dma to only
use the first valid byte.
Now, we only copy useful data to the PBO. It reduce the copy and PBO memory requirement.
It seems a bit faster on native resolution
0: don't dump input texture
1: dump input texture
Now, you can do a first pass with only RT. When you find the wrong call, you can redump the input texture of the bad draw.
deassert gsopen_done before delete the gs object. Compiler and CPU will
reordonate the store (or not because it is a global variable). Probably not
perfect but better.
Got a crash on GSKeyEvent which I guess wasn't thread safe. So let's ensure
gs is open.
1/ initReadFifo will be first called on the GS thread
(openGL can only be done on the GS thread)
2/ readFifo will be called on the EE thread. It is not safe too access eeMem from GS
because of memory is virtual
Fix "recent" regression (crash) on Kingdom heart and others game too.
v2: add a len check on GSState::InitReadFIFO
This hack was used because GSReadFifo was called from the EE thread.
Previous commit move the call to the GSThread.
Hopefully avoid flushing the full GPU contex would improve openGL
performance (at least avoid some hiccups ;) )
Note: newer GSdx ogl won't be compatible with older PCSX2
This fixes the crashes on F9 for me. We don't want to call GSgetTitleInfo2() when GSOpen() isn't finished yet.

* 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)

* GL_ARB_shader_subroutine for perf
fix for nvidia => add missing shader declaration. Nvidia got +4fps on colin3 :)
For the moment only 2 PS parameters are supported. Code need to be extended to support others games that often
switch shader program (like xenosaga).
require GL4 class hardware and the option override_GL_ARB_shader_subroutine = 1
Note: strangely on AMD linux it is slower!
* GL_ARB_shader_image_load_store for accuraccy (Date)
Use a signed integer texture and reenable color buffer writing
Current status: Amagami_transparency.gs & P3_battle_shadows.gs are now working on Nvidia with a small perf impact.
Current implementation detail:
1/ setup the standard stencil as before
2/ on remaining pixel, draw once to compute first primitive that will write a fail alpha value.
3/ final draw based on primitive id of step 2
Note: I think we would get a bad behavior if depth test&mask are enabled on step 2/3
Note2: on my limited testcase the perf impact was on CPU. It would be possible to merge step1&2 to nullifying it (could
even be faster actually), however it would require more GPU power.
Again require GL4 class hardware. And the option UserHacks_DateGL4 = 1

* add a non-working hack: UserHacks_DateGL4, goal was to replace UserHacks_AlphaStencil
+ Detection of good/bad samples is based on primitive ID variable. However I'm not sure
the behavior is always the same between draw call...Anyway let's keep a copy of the current
work
* Dump integer texture into text csv
* add gl4.2 ARB_shader_image_load_store extension (needed by UserHacks_DateGL4)

* allow to switch renderer with F9
* skip first frame in stat of the replayer
* drop msaa. Fxaa and internal resolution will do the job
* move texture attachment from texture object into device object (allow to keep sanely the state)
* split the write buffer and attachment setup
* completely split sampler and texture input setup
* redo GSDeviceOGL::CopyOffscreen to avoid an extra copy.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5704 96395faa-99c1-11dd-bbfe-3dabce05a288
* use gles header file, disable opengl code (mainly GLX, ARB_sso, geometry shader)
* Define properly the function pointer, GLES use basic linking whereas GL must get the symbol dynamically
* cmake: properly search and set libglesv2.so
* don't use dual source blending => HW renderer work (only miss unimportant FBA)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5701 96395faa-99c1-11dd-bbfe-3dabce05a288
* use svnrev.h on linux too
* replace sprintf_s with snprintf (hope it still compile on Windows)
* init integer with 0 instead of NULL
* various int -> u32/uint32/uint on for loop index
* remove a couple of unused variable
* init few variable
* disable unused warning results
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5683 96395faa-99c1-11dd-bbfe-3dabce05a288
* Separate state and shader compilation into separate function
* replace various hash_map by basic array
* Compact VertexScale and offset into a single vec4
* add the new option "ogl_vertex_subdata": subdata is faster on FGLRX, test are welcome on Nvidia drivers
0 => use map/unmap
1 => use subdata
replay: add "linux_replay" option and compute some nice stat (mean, standard deviation)
cmake: recreate shader header at build time
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5682 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
