DrawSyncCallback() enables IRQ for DMA channel 2). DMA -IRQs are only triggered on transfer completion.
\ No newline at end of file +IRQs are only triggered on transfer completion. + +Additional notes by spicyjpeg: + +* The SDK provides no support yet for replacing the BIOS exception handler with +a custom one, however it can be done (if you are ok with losing all BIOS +controller, memory card and file functionality). In order not to break anything +your exception handler must do the following: + + * prevent GTE opcodes from being executed twice due to a hardware glitch (the + nocash docs explain how to do this); + * define _irq_func_table[12] as an *extern* array of function pointers, call + the appropriate entry when an IRQ occurs and clear the respective flag in + register 1F801070h; + * handle syscalls 01h-02h, i.e. EnterCriticalSection and ExitCriticalSection + properly. You should also handle syscall FF00h (invalid API usage), as well + as breaks 1800h and 1C00h (division errors injected by GCC), by locking up + and maybe showing a BSOD or similar; + * overwrite the default BIOS API vectors with a passthrough that checks no + controller- or interrupt-related function is being called. This is necessary + (although ugly) as libpsn00b often calls such functions internally. + +* For some reason mipsel-unknown-elf-nm (symbol map generator) insists on +outputting 64-bit addresses (with the top 32 bits set, e.g. FFFFFFFF80010000) +even when feeding it a regular 32-bit MIPS executable, while the standard x86 +nm tool that ships with most GCC packages prints the proper 32-bit address. +Unclear whether this is a bug, intended behavior or the result of some ancient +ELF ABI flag crap. DL_ParseSymbolMap() will ignore the top 32 bits, so this +should only bother you if you're implementing your own symbol map parser. + +* I haven't worked on psxspu but, for those willing to write some code, this is +the formula to calculate SPU pitch values for playing musical notes ("^" is the +power operator, not xor): + + frequency = (ref / 32) * (2 ^ ((note - 9) / 12)) + spu_pitch = frequency / 44100 * 4096 + + ref = frequency the sample should be played at to play a middle A (MIDI note 69) + note = MIDI note number (usually 0-127, 60 is middle C) + +* If you are overriding any of the memory allocation functions, DO NOT ENABLE +LINK-TIME OPTIMIZATION. GCC has a long-standing bug with LTO and weak functions +written in assembly, also LTO hasn't been tested at all yet. diff --git a/examples/beginner/cppdemo/makefile b/examples/beginner/cppdemo/makefile index 3e122ab..630a280 100644 --- a/examples/beginner/cppdemo/makefile +++ b/examples/beginner/cppdemo/makefile @@ -1,54 +1,65 @@ -include ../../examples-setup.mk +# PSn00bSDK makefile template +# Part of the PSn00bSDK Project +# 2019 -
