This structure fields should match byte-to-byte the layout of MMIO registers:
it is addressed using the MMIO reg address when doing a CP MMIO read. This was
unfortunately not the case, causing CP reads to be mostly broken with the
software renderer.
This option was known to break every second game and only boost a bit.
It also seems to be broken because of streaming into pinned memory and buffer storage buffers.
v2: also remove dlc_desc
Older Qualcomm drivers rotated the framebuffer 90 degrees and this fix didn't work.
Now for some obscene reason it rotates a full 180 degrees.
This can at least be worked around by flipping around the image on our end.
This isn't the cleanup that GLInterface needs, but for now it makes it so it'll swap and not just black screen
A cleanup to GLInterface will be coming in a couple weeks.
On Windows, nvidia don't give us their driver version, so we can't workaround any issues.
As buffer_storage is broken on some drivers, we wanted to disble it for them.
So we can't.
Luckyly only "some" released driver versions are affected as this extension is only available since some months. Let's hope that nobody have to use one of this driver version, else they will get a black screen ...
OSX has their own driver, so performance issues aren't shared with the nvidia driver (unlike the closed source linux and windows nvidia driver). So now they'll also use the MapAndSync backend like all other osx drivers.
fixes issue 6596
I've also cleaned up the if/else block selecting the best backend a bit.
The new chapter title in Paper Mario TTYD had a small graphical bug due to the new code because it read one extra pixel, this fixes it.
I hope this gets everything, I though I had checked most bugs and yet here I am, commit-spamming...
Fixes some remaining bbox related bugs in Mickey's Magical Mirror and a slight graphical glitch in Paper Mario: TTYD when flipping and Vivian as your companion (I've been scratching my head for days to find this one).
Instead of being vertex-based, it is now primitive (point, line or dissected triangle) based, with proper clipping.
Also, screen position is now calculated based on viewport values, instead of "guesstimating".
This fixes many graphical glitches in Paper Mario: TTYD and Super Paper Mario.
Also, the new code allows Mickey's Magical Mirror and Disney's Hide & Sneak to work (mostly) bug-free. I changed their inis to use bbox.
These changes have a slight cost in performance when bbox is being used (rare), mostly due to the new clipping algorithm.
Please check for any regressions or crashes.
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.
