This processorid is a bitmask for which processors the thread can be run on. Bit value zero enables thread execution for this CPUID, bit value one disables thread execution for this CPUID. Bit0-<...> are for CPUID0-CPUID<...>. The thread priority value must be in the following range: 0x0..0x3F. | This processorid is a bitmask for which processors the thread can be run on.

With the New3DS kernel: processorid must be <= <total cores(MPCore "SCU Configuration Register" CPU number value + 1)>. When processorid==0x2 and the process is not an APPLICATION mem-region process, exheader kernel-flags bitmask 0x2000 must be set otherwise error 0xD9001BEA is returned. When processorid==0x3 and the process is not an APPLICATION mem-region process, error 0xD9001BEA is returned. | |||
The stacktop must be aligned to 0x8-bytes, otherwise when not aligned to 0x8-bytes the ARM11 kernel clears the low 3-bits of the stacktop address. | The stacktop must be aligned to 0x8-bytes, otherwise when not aligned to 0x8-bytes the ARM11 kernel clears the low 3-bits of the stacktop address. | ||
