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
enabled by UserHacks_unscale_point_line = 1

Point will be transformed into a NxN square sprite. (N is the upscaling factor)

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 16c2baa0df gsdx-ogl: don't hardcode the accumulation blend trick
Perf impact is bigger than expected

Gregory Hainaut d7c1faf563 gsdx ogl: add GPU timers to measure time between 2 vsync
So far only basic stuff (min/mean/max frame rendering time)
2016-06-26 15:34:36 +02:00
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 5d49a6b685 gsdx ogl: replace 4 VS shader variation by an AND mask
Perf will be roughly the same. However there is a single VS for all
the HW emulation.

Gregory Hainaut 959abe64f8 gsdx ogl: implement wildhack on the CPU
Speed impact is likely small and the plan is only to keep a single Vertex Shader

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

Jonathan Li da2046e90e gsdx: Use alignas instead of __aligned
__aligned is defined in FreeBSD headers and will cause compile errors.

Gregory Hainaut 3ab12cef2f gsdx ogl: accelerate special case of accurate date.
Game often uses date to allow a single pixel pass. If this
use case is detected, stencil buffer will be cleared after first pixels
that pass both depth&stencil test.

It seems to reduce the load on the GPU.

Note: with the help of texture barriere, maybe we could implement the algo
with a single pass.

Gregory Hainaut 5b061e062c gsdx ogl: replace ClearRenderTarget_i by glClearTexSubImage
Avoid state change, avoid potential texture buffer reallocation

Note: require GL_ARB_clear_texture

Gregory Hainaut d41613c46a gsdx ogl: add a Tales of Abyss HLE shader
Again fast and efficient but it relies on CRC

v2: forget to update the precompiled shader...
2016-05-07 22:46:41 +02:00
Gregory Hainaut 14e1ed06df glsl: add an HLE shader for Urban Chaos
Pro:
* Replace 140 draw calls into a single one
* No complex texture conversion/lookup
* smaller solution than a generic solution

Gregory Hainaut c445a14c46 gsdx ogl: extend shader to lookup a single channel 2016-04-28 22:56:38 +02:00
Gregory Hainaut fda511a949 gsdx glsl: extend hw shader to sample depth texture
Will use integral coordinate to avoid any rescaling.

Bilinear interpolation isn't supported. I don't think it is allowed to
filter a depth texture anyway.

Gregory Hainaut 3f404c8edb gsdx-ogl: update shader pipeline intertace to use vs/gs/ps triplet
Better to have 1 function calls with 3 parameters rather 3 functions call with 1 parameter.

Give the compiler more devirtualization hint
2016-04-05 00:01:43 +02:00
Gregory Hainaut decac5fd12 gsdx ogl: implement an empty BeginScene
Compile will devirtualize it and then remove it during the inline.

Gregory Hainaut f8c442cf76 gsdx-ogl: make VS more generic
Texture coordinate could be dummy/float/int integral/int normalized.

Old behavior:
* VS was in charge to select the texture coordinate
* int integral format wasn't supported

New behavior:
* Always compute all formats
* FS will be in charge to select the good format

Impact:
* VS will be slightly slower but it reduces shaders permutation from
   little to 0 (won't be bad for CPU)
* FS speed isn't impacted as 2 separate code paths were already required
  to support both format
* Rasterizer will be 33% slower but unlikely to be the limited factor of
  the GPU
* In future we could directly use the integral format in the FS.

V2: remove useless PSin_t

Jonathan Li cbd2417833 gsdx:ogl:windows: Fix calling convention mismatch
OpenGL does not use the cdecl calling convention (which is the default
calling convention for GSdx on Windows). Since DebugOutputToFile is used
by OpenGL, it needs to use the same calling convention that OpenGL uses.

This fixes a debug build crash when the OpenGL renderers are used and
debug_opengl is nonzero in the ini.

Gregory Hainaut 5fb8c7e65c gsdx: initialize members in constructor of objects
A couple of useless members were removed too.

Also fix wnd initialization

Gregory Hainaut 78569ee833 gsdx-ogl: redo properly the setup of texture format
* add lengthly comment to explain the format
* Likely reduce the number of shader permutation
* Avoid slow AEM (on GPU)

Expect regressions because TC needs some fixes

v2: fix palette mode
2015-09-11 14:14:22 +02:00
Gregory Hainaut ca9b5ce11d gsdx-ogl: move depth conversion shader
Add 2 new shaders:
* ps_main12: cast a 16 bit depth to a RGB5A1 color
* ps_main16: cast a a RGB5A1 color to a 16 bit depth

Shader might be used in future commit as it seems Silent Hill uses this
kind of format.

Fix tab/indentation too

Gregory Hainaut 7002ff3ec3 gsdx-ogl: move texture scale from vs_cb to fs_cb

Gregory Hainaut 6b84a89b6a gsdx-ogl: remove old ati hack for point sampler

Gregory Hainaut c7b2f9d1d2 gsdx-ogl: setup fbo to always write to first buffer
GL_NONE was kind of useless because nothing was attached anyway

Gregory Hainaut 61694013a5 gsdx-ogl: compact blending parameter structure
Save 656B of data. It is good for the cache.

Gregory Hainaut 5b57405517 gsdx-ogl: blend management cleanup
* reorder the blend function

Gregory Hainaut 921b22ac31 gsdx-ogl: drop useless parameter of OMSetDepthStencilState 2015-08-05 22:55:12 +02:00
Gregory Hainaut b7e16b5989 gsdx-ogl: clean the blending management
Intially GSBlendStateOGL was an alias of the m_blendMapD3D9 array

The object was replaced by an index in the array. Save 2k of memory duplication.
And too much useless code.

v2: push/pop blending state in DATE stuff
v3: remove m_state which is useless now
2015-08-05 22:55:12 +02:00
Gregory Hainaut 744f9ebc09 gsdx-ogl: rare corner case when both texture shuffle and date are enabled
In texture shuffle mode the texture data is either RG or BA. It means
that DATE must either checks MSB of G or A.
