Delete the old graphic handling in the IOS7 backend which is not
used anymore after implementing iOSGraphicsManager.
The Accelerate framework is not used anymore. The OpenGLGraphics
manager handles the different color formats.
The ios7 backend implements the graphic handling in the backend code.
iOS supports OpenGL through the OpenGL Framework since iOS 2.0. It's
marked as deprecated but is still shipped with the SDKs for iPhoneOS
and tvOS and will hopefully be so for some time.
The ios7 backend can therefore utilize the OpenGLGraphicsManager to
handle all graphics.
Implement an iOSGraphicsManager class that can be used in the ios7
backend. The iOSGraphicsManager will require some callback functions
in the ios7 backend. createOpenGLContext() will be called to ask the
backend to create an OpenGL context in which the graphic manager can
draw. The function returns the ID of the renderbuffer which shall be
used when creating the framebuffer object this differ iOS from other
platforms). A custom RenderBufferTarget class is added to address
this.
destroyOpenGLContext() will be called to make sure that the old GLES
context is not reused. notifyContextDestroy() does call the function
OpenGLContext.reset() but that will not destroy the context.
refreshScreen() will be called to ask the backend to present the
drawn graphics on the screen. getSystemHiDPIScreenFactor() is called
to get the screen scaling factor. getScreenWidth() and
getScreenHeight() are called to get the width and height of the
surface to draw on.
This commit adds the class but the ios7 backend doesn't make use of
it quite yet. To use it require the ios7 to be a child class of the
ModularGraphicsBackend. That change requires a lot of changes which
will be targeted in separate commits.
Update docportal and github ci worker to only disable the feature
opengl_classic_game since opengl and opengl_shaders are required to
compile the OpenGLGraphicsManager.
- Atari TT support
- all video and audio is now handled via XBIOS
- reworked IKBD handling using Kbdvbase vectors, esp. Kbdvec()
- video uses proper triple buffer
- arbitrary game screen size support
- many fixes and optimizations
The Gecko USB serial adapter is no longer easy to obtain and using
the Ethernet adapter instead is supported by devkitPro/libogc.
However, when enabled, this fails to link when dynamic plugins are
enabled due to missing symbols for gdbstub_getoffsets() found in
devkitPro/libogc/libdb/debug_supp.c. To be exact, this is the
u8 __text_fstart[],__data_fstart[],__bss_fstart[] which should be
implicitly provided by the linker(?)
A monolithic static build with this enabled does succeed, but has not
yet been tested.
- consolidate public #define's (just ATARI)
- cpu compiler flags are specified in the script
- allow explicit move16, SV and SV Blitter features enabled/disabled
Provide two build scripts:
1. "Fat" one targeted at 040/060 machines (possibly with SuperVidel)
This one is optimized for 68020-60 (so it's still possible to try
highres engines on 68030 machines).
2. "Slim" one targeted at 030 machines (Falcon030+DFB/CT2 or TT030)
This one is optimized for 68030 and stripped from even more features:
"fancy" (highres) themes, move16 & SuperVidel routines and most
importantly the highres engines.
After hearing the difference between MAME and DOSBOX OPL I have decided
to keep it available. Some games select it by default (and therefore
the game takes more CPU time) but the reason is valid.
Doesn't save much space but limits the number of options to confuse
users.
For instance if DOSBOX OPL is compiled in, it is automatically used for
the Gob engine which perhaps sounds better but making the engine crawl
without further user interaction.
Saves about 900 KB and relaxes a few games like Toonstruck (11.17% CPU
utilisation) or Bear Stormin' (1.26%).
Not the same as --disable-text-console (USE_TEXT_CONSOLE_FOR_DEBUGGER),
this one is better enabled as it saves a few KBs from Debugger class.
Compile as:
./configure --backend=atari --host=m68k-atari-mint --enable-release --disable-mt32emu --disable-lua --disable-nuked-opl --disable-16bit --disable-scalers --disable-translation --disable-eventrecorder --disable-tts --disable-bink --opengl-mode=none --enable-verbose-build --enable-text-console && make -j 16 && rm -rf dist-generic; make dist-generic
They mostly come from OpenBSD 7.2 and Debian 11 manual pages, and they
shouldn't hurt since backends/networking/enet/source/unix.cpp already
includes them.
- add NDEBUG for smaller file size and better performance when building
with --enable-release
- add exe extensions for both ATARI and FreeMiNT
- use "dist-generic" instead of the clunky ./configure paths
Build as:
./configure --backend=atari --host=m68k-atari-mint --enable-release --disable-mt32emu --disable-lua --disable-nuked-opl --disable-16bit --disable-scalers --disable-translation --disable-eventrecorder --disable-tts --disable-bink --opengl-mode=none --enable-verbose-build && make -j 16 && rm -rf dist-generic; make dist-generic
