* Matched perspective, contquery, contreaddata, recvmesg and sendmesg * Fixed libultra compilation flags * Matched viblack * Matched virepeatline, visetmode, visetspecial and viswapbuf * Matched cartrominit, dpsetstat, sptask, sptaskyield, visetevent, createthread, gettime, setthreadpri, settime, settimer and starthread * Fixed bss bs * Matched even more libultra stuff * Matched even more * __osRdbSend * Decompiled most of the functions of libultra <3 * Matched last functions * Added a separation to libultra macros * Removed ARRLEN from controller.h * Fix libultra warnings --------- Co-authored-by: Alejandro Javier Asenjo Nitti <alejandro.asenjo88@gmail.com>

* Not every task ucode would need/use every field, but
|
|
*
|
|
* - type (audio, gfx, video, ...)
|
|
* - flags
|
|
* - wait for DP to drain before running new task

|

|

|
|
* IMPORTANT!!! Watch alignment issues.
|
|
*
|
|
* IMPORTANT!!! Watch data cache issues. The RCP may write data into the
|
|
* dram_stack, output_buff, output_buff_size, and the yield_data_ptr areas.
|
|
* These buffers should be cache aligned and use the entire line (16 bytes) to
|
|
* avoid corruption by writebacks by the CPU (cache tearing).
|
|
*
|
|
* IMPORTANT!!! all addresses are virtual addresses. Library does
|
|
* any necessary translation.
