Logic is now based on + Sony's code but more efficient and can return total number of vblanks + elapsed, number of hblanks since last call and wait up to n vblanks + specified by an appropriate argument value. It will also generate a + timeout when vblank interrupt stops working and would attempt to + restart it. + +* psxapi: Added gets() and getc() BIOS functions. + +* psxapi: Corrected a putc()/putchar() discrepancy. putc() puts a character + to a file stream, putchar() puts a character to stdout. + +* Completely revised library reference manual with better formatting and + more functions documented. + +* psxgpu: Added DrawSyncCallback(). + +* psxgpu: Implemented DMA interrupt callback system with DMACallback() + allowing to handle DMA interrupts very easily. + +* libpsn00b: Implemented Serial I/O library (psxsio) with serial tty device + (installed using AddSIO) and serial callback support. Serial library + is also fully documented. + +* psxgpu: Implemented IRQ callback system with InterruptCallback() allowing + to set interrupt callbacks very easily. + +* psxgpu: Implemented proper IRQ handler installed using HookEntryInt or + SetCustomExitFromException() for handling VSync and other interrupts. + ChangeClearPAD(0) must now be called after _InitPad() or vsync timeout + will occur. + +* libpsn00b: Started making local labels prefixed with .L instead of . making + them not appear in symbol lists resulting in a cleaner symbol dump. Still + not possible to do function-scope local labels like in ASMPSX because GAS + syntax is ASS (or ASS GAS which is farts, GAS is farts). + +* psxgpu: DrawSync() function now waits for DMA completion and GPU transfer + ready instead of simply waiting for GPU transfer ready which is the likely + cause of subtle GPU related timing issues, it also sets GPU DMA transfer + mode to off afterwards. It can also read number of words remaining in DMA + transfer if a0 is non-zero but it likely only returns the correct value on + VRAM transfers. Exact way how DrawSync() returns the count in the official + SDK is currently unknown. + + + +06-07-2019 by qbradq: + +* lzpack: Swapped a buffer length litteral with sizeof operator, fixing a + stack overflow bug in some instances. + + + 05-23-2019 by Lameguy64: * Added dev notes.txt file in docs that includes notes about the many - quirks discovered about the system throughout the development of this SDK. + quirks about the console discovered during the development of this + SDK project. * Updated libn00bref.odf a little. +* Added turboboot example. + * Added rgb24 example. -* Made stack usage in ResetGraph() less wasteful. +* Got custom exit handler set using SetCustomExitFromException() (BIOS + function B(19h)) working. Currently used to acknowledge VSync IRQ but + actual VSync handling is still done with events and needs to be + transferred to the custom exit handler. At least it lets BIOS + controller functions to work now. See doc/dev notes.txt for details + on how this handler behaves. + +* Made stack usage in ResetGraph() less wasteful. You only need to + allocate N words on stack based on N arguments of the function + being called. -* VSync IRQ handling now done using a custom exit handler. Actual VSync - handling is yet to be moved to the custom exit handler though. +* VSync IRQ handling now done using a custom exit from exception handler. + Actual VSync handling is yet to be moved to the custom exit handler + though. * Made stack usage in start.s of libc a lot less wasteful. |
