Compile time toggling of features like fonts

Ghabry commented 4 years ago

The Player bundles many Fonts. I see use cases where font packs can be disabled (e.g. to reduce the memory footprint on devices where the entire ELF is copied into memory - homebrew stuff) Also useful for commercial releases: An English game only needs English glyphs.

TODO: Make a list of all the fonts

Ghabry commented 12 months ago

This semi fits here as the fonts are large: I analyzed the Player using bloaty.

tl;dr: Disabling everything and removing built in fonts and encoding support will bring us down from 12 MB to around ~5-6 MB. Everything includes audio making the barely pretty useless. Removing encoding support will break Chinese/Japanese/Korean games. Afterwards there is no simple way to get even smaller. We just have too much functionality in it.

A saving of 1 MB means that the game can load ~3.4 pictures of size 320x240 more. So this can help a bit in low memory conditions.

Note that bloaty requires debug symbols for certain features which increase the size of the binary. Debug symbols are not part of the final binary but part of the calculation.

symbols is for specific functions. compileunits lists the size per file (though this can be inaccurate). This is just a different way to represent the information. I output 10 entries per section (different locations in the executable where stuff is stored).

I couldn't get .eh_frame (exception handling) disabled. Was even generated with -fno-exceptions. This is usually disabled to save space (around 0.5 MB).

Player build that has all features enabled and compiled static against the libraries

``` cmake --preset linux-relwithdebinfo -DPLAYER_BUILD_LIBLCF=ON -DCMAKE_CXX_FLAGS="-Os -g" ``` ``` bloaty -n 10 -d sections,symbols easyrpg-player-all --debug-file=easyrpg-player-all.debug FILE SIZE

tl;dr 7.30MB

What you can see is that disabling audio and freetype reduces the executable size from 12.1MB to 7.30MB. Is of course not desired to have all the audio disabled but just so you can see what the "base size" of a minimal Player is. Still pretty large.

The largest offenders when having everything enabled appear to be fluidsynth with this weird rand_table. rand_table is some dithering table in fluidsynth. No idea what the purpose is but this is very large. Maybe can be patched out without impacting quality too much?

icudt69_dat is the ICU encoding table. Most of the size comes from CJK encodings. Removing support for them gives us alot of hate but should save around 600 KB :P (we still need the table for european encodings and normalisation).
BITMAPFONT_WQY is the Chinese pixel font. Another 600 KB.
SHINONOME_GOTHIC is mostly the Japanese font but also some Latin extended glyphs etc.
TTYP0 another font with lots of latin glyphs
hard_light lookup table for the Tone blit. Cannot be removed.

Getting rid of some fonts and breaking many games around the world will likely save 1.2 MB. Problem is that we cannot say "use a TTF font" here because enabling Freetype takes 1 MB...

I ported EasyRPG to the Dreamcast and there's quite a lot more that can be done. (Note that my observations were done with LTO enabled)

For your information, the Dreamcast has 16MB of RAM along with 8MB of VRAM and 2MB of SPU RAM. However, because EasyRPG only has a software renderer available, the VRAM only ends up being used for the framebuffer and the SPU RAM also sits unused.

First thing i did was to remove the spanlite dependency in liblcf (instead using std::span directly) and partially switch to std::format instead of libfmt. Doing both save an additional 600kb or so. (it may be possible to save more by keeping libfmt with https://vitaut.net/posts/2024/binary-size/ but using std::span but i didn't have much luck with that).

Disabling the RTP routines saved a bit but it was a minor improvement. Disabling most built-in fonts except rmg2000 yielded quite a big improvement, i believe it was 1Mb+ for the japanese fonts alone. (removing ttyp0 gave me a very small benefit by comparison)

Disabling translations yielded a similar improvement to disabling RTP stuff, nothing huge.

Enabling mp3 decoding with mpg123 only adds an additional ~100kb... I did have to use the following :

-disable-components --disable-libsyn123 --enable-libmpg123 --disable-32bit --disable-largefile --disable-feature_report --disable-messages --disable-moreinfo --disable-id3v2 --disable-debug --disable-icy --with-cpu=generic_float --disable-real --disable-int-quality --enable-lfs-alias

Note that on some platforms, you may need largefile support (or you may have to enable 32-bits output support) but the rest doesn't really matter in the context of EasyRPG. Enabling portable mode in mpg123 unfortunately leads to linking errors... i don't know if that can be avoided.

Pixman is a huge dependency, unfortunately there's no real alternative in EasyRPG right now. Previously it was super slow with 16-bits in particular but thanks to ghabry's 16bit, it's a lot better (more so than 32bpp was even) albeit still not perfect. 16-bits support (On Dremcast, it's done by having an internal A1R5G5B5 buffer that's then uploaded to VRAM with Store Queues and displayed with PVR) not only helps with performance but also saves on memory.

For audio, i wasn't able to do much but to use a stripped down version of SDL with only audio because i encountered issues trying to make it work with sndstream from KOS... If it weren't for MIDI support, i would have bypassed Drwav and stuff altogether and just used the native audio functions.... except that won't be possible either because there's a limit of 64kb on audio samples ! (i do believe it could be possible to stream them but then it becomes rather annoying) In any case, audio works mostly fine but i'm still not 100% happy. And because we use SDL, we cannot support hardware ADPCM support either.

KallistiOS on Dreamcast currently lacks multi-sector support for DMA from CD device (only per sector)... As a result, trying to load a file results in high CPU usage, which is quite bad. To be clear, that's not an issue with EasyRPG. I hope this will be addressed in the future.

I compared the midi implementations on Dreamcast and overall, FMMidi is still the best when it comes to CPU and memory usage. Fluidlite even with the smallest soundfont available (4.7kb) is still slower than FMMidi. That said a while back, it was not my experience on the RS-90, fluidlite was quite faster by a significant margin. But at least the Dreamcast, that's not the case anymore.

Disabling the built-in EasyRPG logo saves a few kbytes, which is not negliable in a low memory situation like the Dreamcast.

What EasyRPG could do :

Allow for built-in fonts to be easily selectable at compile time. (or allow a compile switch for TINY that only allows rmg2000)
Hide translations behind an optional compile time define.
Same for RTP, some games don't require this, and in the case of the Dreamcast it does not even matter, as RTP assets could be provided with the games.
Consider a switch to C++20. There are big memory savings with std::format / std::span in my experience, and libfmt can be problematic to compile on some platforms.
Allow for cache size to be reduced at compile time. (CACHE_SIZE_DEF in cache.cpp, audio_secache.cpp)
EXE_Reader support to be disabled (saves a few kbytes), it's done so for EMScripten.
Allow for built-in logo to be disabled and autoskip.
EP_MIDI_FREQ in audio_midi.h to be easily tweakable at compile time. (3DS and Wii hardcode this to 22050hz)
Make ZIP support optional (not even remotely usable on some hardware, but it could help in some cases).
Allow logging support to be disabled (Noticeable decrease in code size).

These would be nice to have but obviously require a lot more work :

LodePNG or similar implementation for png support. This could then allow for zlib support to be optionally opted out. (libpng needs zlib)
Add a minimp3 backend. While mpg123 is okay as it is, i believe making use of minimp3 would be more pain free for some platforms and has potential to be even smaller.
Replace pixman with something else. Unfortunately i encountered many issues with this POS, many of them related to performance. It does not even build with GCC15 out of the box.
Have the possibiltiy of having a hardware backend for drawing bitmaps/transitions etc... Dreamcast does have OpenGL 1.2 support with glDC so i think this could be a good path.

On my branch right now, with drwav/mpg123 and my custom dreamcast backend along with some modifications above that i did, -Oz brings it down to 3.1mb. However Oz has a significant performance penalty. -O3/Ofast increases this to 3.7mb but the games are much faster (3x times faster in fact). It appears that drawing/pixman is still a significant performance bottleneck in my experience.

Ghabry commented 2 weeks ago

The performance bottleneck is probably because the rendering code heavily relies on inlining.

On low optimisation fetching the rgb-bit-mask requires 3 function calls and 3 registers. On O2 the compiler replaces the calls with constants. So more free registers and less function call overhead.

Same likely happens with our getters/setter just not as bad in terms of perf

gameblabla commented 2 weeks ago

Yeah that's probably it altho O2 only addresses the issue with rendering, using O3 instead increases the performance further in some other cases that i can't exactly pinpoint out yet.

I did a test implementation of EasyRPG with no zlib, only Miniz and SPNG and the code size dropped by about 80 kb with LTO. (along with using miniz.h for stuff that do use crc32. XYZ also relied on zlib but i switched it to miniz as well) https://github.com/gameblabla/Player/blob/5fae74ee429991cf469fc938aff1de1ed7b2e8b3/src/image_png.cpp

Not a huge improvement but still enough to allow me to allocate a small image or charset. I can't think of much less. I may attempt minimp3 later but i don't expect huge savings either given that mpg123 is only about 100kb or so in final build. (according to github repo, i would save about 50-60kb or so)
