Ryan Houdek eb3b933dd0 Remove all instances of OpenCL in the Dolphin Project. A brief history of OpenCL in Dolphin. OpenCL was originally added to the Dolphin codebase 1 month after it was released with OS X Snow Leopard in 2009. OpenCL was one of the largest group projects that Dolphin ever has had. The OpenCL texture decoder was originally aded with version 1.0 of the OpenCL spec; This version didn't have the capability of a OpenCL-OpenGL interop which would allow for uploading textures once and have it decoded directly to a OpenGL texure. This was to be worked out when the OpenCL 1.1 spec was released and allowed the interop. This work has never been done, and no one in the team is willing to work on it for various reasons. OpenCL has had the unreasonable expectation that it increases the performance of video games that require a large amount of EFB copies like NSMBW. In reality, enabling OpenCL just put the graphics card in a higher power mode which increased the game speed. This is due to the unfortunate effect of Dolphin tending to not push GPUs out of their lower frequency power savings modes. Thanks to everyone that had contributed to the OpenCL texture decoder. 2013-12-11 15:15:55 -06:00

degasus edc879ce48 OpenGL: fix crash in revision 95aeedec19
Real xfb didn't provide any read_stride, so there is a division by zero.

This commit calculates the correct read_stride for real_xfb, so there is also no hack for texture vs xfb needed.

degasus 95aeedec19 OpenGL: readback efb2ram with different strides at once
This is done with a pixel buffer object. We still have to stall the GPU, but
we only do it once per efb2ram call.
As the cpu can't access the vram, it has to queue a memcpy for the gpu and
wait for the gpu to finish this copy. We did this for every cache line which
is just stupid. Now we copy the complete texture into a pbo and readback this
at once. So we don't have to wait for lots of round-trip-times.

degasus 230e12ae8c OpenGL: also remove VAO from xfb convertion
We use attributeless rendering, so officially we have to bind _any_ VAO.
As the state of this VAO doesn't matter, we don't have to switch it.

Also fix an AMD issue as they don't like to render from an empty VAO.

degasus d410fe7c96 OpenGL: cleanup yuv2rgb (real xfb) workflow
We neither scale nor render from subimages, so we by using gl_Position, we don't have to generate _any_ vertices for this converting.

Also remove the glTexSubImage optimization as every driver does it when needed. But there are some workflows (eg on APU) where it's better to realloc this texture instead of a second memcpy or stall.

Scott Mansell b5bd2ba847 OpenGL: Enable filtering for EFB to Real XFB copies.
This fixes Real XFB Jaggies in OpenGL on games which use yscaling, such
as most PAL games.

This fixes the last of the "Real XFB Macroblocking" issues for opengl,
see issue #6503

Scott Mansell e6b35642df Fix Desktop GLSL versions in the recent changes.
Seems OpenGL ES 3 Requires you must have an lod argument, while Desktop
versions require you must not have a lod argument if you are using a
Sampler2DRect (which doesn't do Mipmapping).

degasus 0753ce5bda ogl: use GL_RGBA instead of GL_RGBA8
8 bit per pixel is _everywhere_ the default, so we don't need to define it explicitly.
Also we don't rely on exact 8 bit resolution.
