Gregory Hainaut deb2ed3d09 gsdx ogl: reimplement merge circuit to support feedback write 2016-10-14 18:13:20 +02:00
Gregory Hainaut 7ca9ca9465 gsdx: new parameter for merge virtual function
* Add full PMODE register to replace slbg/mmod
* Add full EXTBUF register (will allow to emulate write feedback)
* Add a third source (which will actually be the destination of the
  write feedback)

Gregory Hainaut fbf7ccbdda gsdx: by default new will throw std::bad_alloc

Gregory Hainaut 5ced9c1f19 gsdx mipmap:ogl: plug trilinear/mipmap2 option
mipmap option 3. Actually maybe a separate tri-linear option will be better

m_mipmap == 2 => use manual PS2 trilinear/mipmap
Otherwise
m_filter == 3 => always use full automatic trilinear interpolation
m_filter == 4 => use automatic trilinear interpolation when PS2 uses mipmap
m_filter == 5 => like 4 but force bilinear interpolation inside layer

Gregory Hainaut a8a2db8eb1 gsdx mipmap:ogl: extend HW sampler with tri-linear filtering
v2:

Gregory Hainaut 344636d88e gsdx ogl: attach input texture before copy
Help to ensure with copy the good texture in debugger

Gregory Hainaut 677f890c5c gsdx debug: static GSState::s_n
This way you can access the current draw call anywhere. Very useful for debug.

Gregory Hainaut 61333ecb40 gsdx debug: trace register access
I didn't include high frequency register such as vertex stuff

main goal is to give the possibility to trace the texture/clut update

Gregory Hainaut c2b67ccb78 gsdx ogl: implement an alternate shader for Jak Shadows
The game sets the framebuffer as an input texture. So I did the same for
openGL. Code is protected with a CRC. It is working because the game want to sample
pixels.

For the record, I tested it GTA too, it doesn't work as expected because
the game will resize the framebuffer to a smaller one. So you don't have
the guarantee that pixel will be read before a data write.

Note: it requires at least accurate blending set on basic

Note: I need CRC of all Jak games that suffers of this issue. Thanks you :)

Gregory Hainaut 018895067b gsdx ogl: restore code to unscale point

Gregory Hainaut 2e7fab7813 gsdx sw: avoid aliasing issue, clear function was wrong anyway
Value must be un-normalized. Function is only used with 0.0 so
API was updated to only use the 0 case.

Gregory Hainaut 85fb55a0e1 gsdx ogl: memory management take 3
Add a factor 2 on the VRAM to get the quantity of available memory for the textures.
The driver is allowed to put some textures in RAM. Of course it is bad for performance
but it won't crash.

Due to the 4GB by process limit, I keep a (reasonable) maximum of 3.8GB.

In order to avoid a crash when memory is too low an exception will be risen
with no guarantee on rendering and big performance impact. In this situation
you ought to reduce upscaling/disable large framebuffer.

Gregory Hainaut a2086ed458 gsdx profiler: drop latest frame time
Value is out of the chart. I'm not even sure it is a real frame so let's just remove it.

Gregory Hainaut 3f03f7333c gsdx: improve builtin profiler
* Does the first vsync (start counter) after the sleep
* Dump data after the rendering, avoid to count extra destructor,sleep time
* Dump data into a basic csv file (if people want nice graph)

Requirement
* dedicated GPU (ofc!)

Gregory Hainaut a065a1d918 gsdx ogl: don't use GL_ARB_clear_texture for the depth buffer
It creates some slowdowns for unknown reason. My best hypothesis is
that stencil will be cleared too which is slow.

Let's keep the code for the future when stencil will be dropped.

Fix #1420

Gregory Hainaut 79587215bb gsdx ogl: add the option force_texture_clear for test purpose
Might be completely useless.

1 => always clear framebuffers and textures to black (aka 0)
2 => always clear framebuffers and textures to red

Gregory Hainaut 3234c8241b gsdx ogl: massively extend glsl self test
* Support Mesa Nouveau IR (free driver for Nvidia's GPU)
  => Print intermediate representation + final shader
  => Dump GPR usage
* Move dumped shader in /tmp/GSdx_Shader/<sub_dir>
  =>  Avoid the landing of 3 thousands of files in $PWD ^^
* Use function instead of macro

Gregory Hainaut f7ddd488e1 gsdx ogl: Extend uniform buffer with channel parameter
Instead to use the standard ps ubo which is used every draw call.
I reused a barely used buffer to reduce the extra cost of the upload

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)
