The only two devices that do this are Mesa software rasterizer and Intel Ironlake(With a few hacks).
Basically since it doesn't support OpenGL 3.0, it can't grab the version the new way.
So failing that, it sets to GL 2.1, and continues.
Further along, on Ironlake at least, it tries grabbing the extensions the new GL 3.0 way and fails.
So have a fallback that grabs the extensions string the old way, in probably the most elegant way possible.
The old way was to use big switch/case statements based on a type of buffer.
The new one is to use inheritance.
This change prohibits us to change the buffer type while running, but I doubt we'll ever do so.
Performance should also be a bit better. Also a nice cleanup.
Added some comments about this different kind of buffers.
This is a bit slower on map_and_* because of flushing and _very_ much slower on buffer(sub)?data because of a new memcpy.
But this design allow us to decode directly into a gpu buffer, eg vertexloader will profit :)
gl.h and glext.h provide most of the function pointer typedefs and defines for extensions and core features.
The only one it doesn't provide is GL 1.1 function typedefs, but this is to be expected.
If anything needs defines or typedefs in their header in the future, that's as easy as before.
Prior to this commit it was possible to assign the same keycode to more than one button.
ie. Say I assigned Open with the hotkey Ctrl+O; well, it was possible to also add it to another function as well, which leads to hotkey clashing.
Now, say I assign Open with Ctrl+O, but then assign that same hotkey to Refresh List; it will unbind the hotkey from Open and then assign it to refresh list.
- Spaces -> Tabs | Consistency
- Javadoc everything that was added and not documented.
- Remove duplicated code regarding the adapter that used to reside in DolphinInfoFragment.java. Now it resides in AboutActivity.java without a second duplication of it.
- Properly retrieve all of the contexts in the EGL initialization in EGLHelper.java.
- Remove the attribute EGL_RENDERABLE_TYPE from the pbuffersurface attributes in EGLHelper.java. With this present, the EGL context will always fail to reinitialize if destroyed and attempted to be recreated.
- Break the inner class Limit within GLES2InfoFragment.java, GLES3InfoFragment.java, and GLInfoFragment.java into its own single class. Greatly reduces code duplication.
- Introduce a Type enum into Limit.java (one of the wildly rare cases in Java where an enum is actually an OK solution). Removes duplicated constants from the Java files stated in the previous bullet note.
- Add a copyright comment to the top of EGLHelper.java. Forgot to do this initially, my bad.
- Add some missing override annotations to GLES2InfoFragment.java, GLES3InfoFragment.java, and GLInfoFragment.java.
- Use StringBuilders in the previously mentioned three Java files. This is better than using a String in this instance, as the String object won't have to be recreated multiple times (ala concatenation).
- Fix some constant accessors in the previously mentioned three Java files.
- Added the 'final' modifier to the above three classes and to Limit.java. These classes serve a single purpose only, and are not intended to be inherited.
There is a /lot/ of information in these tabs, we may have to think about changing how the information looks
OpenGL isn't done yet since there are a million limits on desktop GL, may just show a few things and extensions there.
This one was introduced to reduce the glBindTexture and glActiveTexture calls. But it was quite a bit of logic and only an improvment on uploading/creating a texture, which is done rarely.
This adds xfb support to the videosoftware backend, which increases it's
accuracy and more imporantly, enables the usage of many homebrew apps
which write directly to the xfb on the videosoftware backend.

I give up. Merging the ppc_fp branch has caused issues in numerous games
and I can't find the bug. I'm leaving this merged to enable easy
recompilation for people who would like to play games that benefit from
non-IEEE mode emulation (e.g. Starfox Assault).
This branch is the final step of fully supporting both OpenGL and OpenGL ES in the same binary.
This of course only applies to EGL and won't work for GLX/AGL/WGL since they don't really support GL ES.
The changes here actually aren't too terrible, basically change every #ifdef USE_GLES to a runtime check.
This adds a DetectMode() function to the EGL context backend.
EGL will iterate through each of the configs and check for GL, GLES3_KHR, and GLES2 bits
After that it'll change the mode from _DETECT to whichever one is the best supported.
After that point we'll just create a context with the mode that was detected
As we do lots of writes to *Iptr, the compiler isn't allowed to cache any shared variable (neither index nor Iptr itself).
This commit inlines Iptr + index into the index generator functions, so the compiler know that they are const.
We are used to render them out of order as long as everything else matches, but rendering order does matter, so we have to flush on primitive switch. This commit implements this flush.
Also as we flush on primitive switch, we don't have to create three different index buffers. All indices are now stored in one buffer.
This will slow down games which switch often primitive types (eg ztp), but it should be more accurate.
add the GL include (back) to Base.props
use a similar technique to GLX.cpp (by Sonic) in WGL.cpp to get
wglSwapIntervalEXT without the WGLEW check

This "u32 components" is a list of flags which attributes of the vertex loader are present.
We are used to append this variable to lots of vertex generation functions, but some of them don't need it at all.
The usual way to handle this kind of request is to rise a flag which the gpu thread polls.
The gpu thread itself either generates the result or just write zeros if disabled.
After this, it rise another flag which says that this work is done.
So if disabled, we still have the cpu-gpu round trip time. This commit just returns 0 on the cpu thread
instead of playing ping pong...
Move enums for max SI and EXI devices to their respective .h file, and rename them.
Use only those enums in BootManager.cpp. Same thing in Movie.cpp
Change one instance of MAX_BBMOTES to MAX_WIIMOTES in Movie.cpp, since movies do not support balance board.
Some information on this bug since this isn't quite true.
Seemingly with the v53 driver, Qualcomm has actually fixed this bug. So we can dynamically access UBO array members.
The issue that is cropping up is actually converting our attribute 'fposmtx' to an integer.
int posmtx = int(fpostmtx);
This line causes some seemingly garbage values to enter in to the posmtx variable.
Not sure exactly why it is failing, probably them just not actually converting the float to an integer and just handling the float directly as a integer.
So the bug is going to stay active with Qualcomm devices until we convert this vertex attribute from a float to a integer.
Let's talk a bit about this bug. 12nd oldest bug not fixed in Dolphin, it was a
lot of fun to debug and it kept me busy for a while :)
Shoutout to Nintendo for framework.map, without which this could have taken a
lot longer.
Basic debugging using apitrace shows that the heat effect is rendered in an
interesting way:
* An EFB copy texture is created, using the hardware scaler to divide the
texture resolution by two and that way create the blur effect.
* This texture is then warped using indirect texturing: a deformation map is
used to "move" the texture coordinates used to sample the framebuffer copy.
Pixel shader: http://pastie.org/private/25oe1pqn6s0h5yieks1jfw
Interestingly, when looking at apitrace, the deformation texture was only 4x4
pixels... weird. It also does not have any feature that you would expect from a
deformation map. Seeing how the heat effect glitches, this deformation texture
being wrong looks like a good candidate for the problem. Let's see how it's
loaded!
By NOPing random calls to GXSetTevIndirect, we find a call that when removed
breaks the effect completely. The parameters used for this call come from the
results of methods of JPAExTexShapeArc objects. 3 different objects go through
this code path, by breaking each one we can notice that the one "controlling"
the heat effect is the one at 0x81575b98.
Following the path of this object a bit more, we can see that it has a method
called "getIndTexId". When this is called, the returned texture ID is used to
index a map and get a JPATextureArc object stored at 0x81577bec.
Nice feature of JPATextureArc: they have a getName method. For this object, it
returns "AK_kagerouInd01". We can probably use that to see how this texture
should look like, by loading it "manually" from the Wind Waker DVD.
Unfortunately I don't know how to do that. Fortunately @Abahbob got me the
texture I wanted in less than 10min after I asked him on Twitter.
AK_kagerouInd01 is a 32x32 texture that really looks like a deformation map:
http://i.imgur.com/0TfZEVj.png . Fun fact: "kagerou" means "heat haze" in JP.
So apparently we're not using the right texture object when rendering! The
GXTexObj that maps to the JPATextureArc is at offset 0x81577bf0 and points to
data at 0x80ed0460, but we're loading texture data from 0x0039d860 instead.
I started to suspect the BP write that loads the texture parameters "did not
work" somehow. Logged that and yes: nothing gets loaded to texture stage 1! ...
but it turns out this is normal, the deformation map is loaded to texture stage
5 (hardcoded in the DOL). Wait, why is the TextureCache trying to load from
texture stage 1 then?!
Because someone sucked at hex.
Fixes issue 2338.
At the moment, custom textures with:
- invalid mipmap size
- invalid aspect ratio
- non-fractional scaling factors
are allowed. But they can't be loaded fine by the backend, so generate a warning if someone trys to load them.
fixes issue 6898
OpenGL defaults are GL_REPEAT, which is even more unlikely than GL_CLAMP_TO_EDGE.
As I can't test the behavoir of the real hardware, I changed it to how it works before,
but I guess just clip the texture makes more sense.
Some settings that bootmanger reads from game ini can be changed while a game is running, so we don't have to revert these back to what they were when starting the game, unless they were actually changed by the game ini.
Fix signed/unsigned warnings that pauldacheez pointed out.
It didn't make sense. The math was nonsensical. Calibration data was somehow applied twice. I don't even.
This reverts commit 4dad640d5f.
Fixed issue 6702.
SSE do support non-vector instructions, but they _all_ overwrite the dest register
if the src location isn't a register. (wtf?)
So we have to load the src into a temporay register :(
