Gregory Hainaut a573ce185c gsdx-ogl: mark GL_EXT_shader_io_blocks as mandatory for GLES 2014-10-02 20:44:22 +02:00
Gregory Hainaut d37cc8e1e7 gsdx-ogl: GL_ARB_shading_language_420pack is now mandatory
All API/drivers support it so time to remove the fallback.

Gregory Hainaut f46e8cc6ac gsdx-ogl: bump base requirement to 3.3
A couple of fallbacks were introduced for the Mesa driver that only support 3.0
DSA will require a recent Mesa which already support GL3.3

Require at least SandyBridge for Intel GPU

Gregory Hainaut 594f6c33a2 gsdx-ogl-ES: require GL_EXT_shader_io_blocks + GLES3.1

Note: on the GL API it will require GL3.3 (see next commit)

gregory.hainaut 3d7b86660a gsdx ogl: Enable by default advance DATE effect on nvidia (GL4 GPU)
Note: DATE is used for shadows (persona 3) and others effect

You can disable it when you disable gl image extension (override_GL_ARB_shader_image_load_store = 0)
You can also enable it on AMD too (set it to 1 this time) but no guarantee.

If you feel the extension is too slow, you can try disable some gl barrier (aka "damn the torpedo full steam ahead!").
It can be done with the option UserHacks_DateGL4 = 1. Otherwise just disable the extension.

Note: don't enable UserHacks_AlphaStencil in the same time. GL_ARB_shader_image_load_store is an alternative implementation.
Enabling both in the same time will lead to undefined (well surely wrong) behavior.

gregory.hainaut 84895eadd9 gsdx ogl: correct most of Z-depth issue
Best setting if you driver support GL_NV_depth_buffer_float => GL_NV_Depth = 1 & logz = 0
Otherwise => GL_NV_Depth = 0 & logz = 1

Explanation of the bug:
Dx z position ranges from 0.0f to 1.0f (FS ranges 0.0f to 1.0f)
GL z Position ranges from -1.0f to 1.0f (FS ranges 0.0f to 1.0f)

Why it sucks:
GS small depth value will be "mapped" to -1.0f. In others all small values will be 1.0f! Terrible lost
of accuraccy.

The GL_NV_depth_buffer_float extension allow to set the near plane as -1.0f.
So
"GL z Position ranges from -1.0f to 1.0f (FS ranges 0.0f to 1.0f)"
will become
"GL z Position ranges from -1.0f to 1.0f (FS ranges -1.0f to 1.0f)"
and therefore
"z posision [0.0f;1.0f] will map to FS [0.0f;1.0f]" as DX

Yes we just get back all precision lost previously :)
However you need hardware (intel?) and driver support (free driver?/gles?) :(

gregory.hainaut e80b002929 gsdx ogl: Flush various pending work
* 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)

gregory.hainaut e01c6cd9ce gsdx ogl: the proof of concept commit
* 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

gregory.hainaut 07605941ef gsdx ogl:
* some preliminary work to test/benchmark bindless texture in the future (glsl was not yet updated)
Bindless texture allow to get a GPU texture pointer and then set it directly
to the shader as a basic uniform.
=> no more texture unit selection/validation
=> no more texture validation neither texture hash lookup

3rdparty: update gl header to the latest gl4.4

gregory.hainaut b4084047be gsdx ogl: Used a basic flat interpolation for color interpolation (line & tri primitives)
Card that support gs:
remain only a gs to generate sprite from a line. Even dummy gs are costly for the GPU.

Card that don't support gs:
remove useless copy of color for line and triangle primitives

Note for dx: opengl 3.2 (maybe not gles) supports both flat interpolation
convention (GL_FIRST_VERTEX_CONVENTION or GL_LAST_VERTEX_CONVENTION).  It might
be possible to shuffle vertex index to put the last vertex in first position.

- buff[0] = head + 0;
- buff[1] = head + 1;
- buff[2] = head + 2;
+ buff[0] = head + 2;
+ buff[1] = head + 1;
+ buff[2] = head + 0;

gregory.hainaut 0f603a98d5 gsdx ogl: Test the ARB_shader_subroutine GL4.0 extension
The idea was to replace shader program swith by pointer function calls inside
shaders.  At least parameters that are often changed between draw call. So far
I only ported atst and colclip. Unfortunately code is "slower" (on GSdx standalone).
For the moment keep the code but disabled.

If I understand well the validation of program is done in the "driver thread"
but the additional call are done in the overloaded MTGS thread. Apitrace
profiling shows faster GPU draw calls. Another possibility is that the driver still
need to validate the draw call because of others state change.

Here some stats on colin3 (90 frames):
without subroutine: UseProgram 125246
with subroutine: UseProgram 2906, subroutine 125945 => 3605 extra calls overhead (not
all parameters are ported to subroutine)

* redo texture unit management. Unit 0-2 for shaders, Unit 3 for texture operations. MultiBind will allow to bind

* 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

gregory.hainaut 58cc2ddd1f gsdx-ogl-wnd:
* Remove bad redefinition of glActiveTexture and glBlendColor pointer
* Remove glew dependency on linux
* s/OGL_DEBUG/ENABLE_OGL_DEBUG/ and enable it on debug

gregory.hainaut b65ad2c3e5 gsdx-ogl-wnd:
* move GL loading function into its own namespace
* Use manual GL loading on linux too and mostly drop glew dependency. (Not 100% clean we are still depends on some glew define, it will be fixed later)

Note: shaders still need to be copied manually from GSdx/res to bin/plugins
