Why use it
It provides direct, allocation-conscious access to PSX kernel ownership, interrupts and low-level services. No exception-based error path is implied by the signature.

Sets an ISR callback for a given DMA channel.
Declaration
Declaration
unsigned registerDmaEvent(DMA channel, eastl::function<void()>&& lambda)Sets an ISR callback for a given DMA channel.
| Parameter | Type | Meaning |
|---|---|---|
channel | DMA | Value supplied for channel. Keep referenced or pointed-to data valid for the complete call. |
lambda | eastl::function<void ()> && | Value supplied for lambda. Keep referenced or pointed-to data valid for the complete call. |
Returns: unsigned int — unsigned A slot id for the given callback.
Example
C++ example
#include "psyqo/kernel.hh"
// Assume these named values have been initialized with valid data:
// DMA channel
// eastl::function<void ()> && lambda
auto result = psyqo::Kernel::registerDmaEvent(channel, lambda);Trade-offs and warnings
Pointer/reference arguments are borrowed unless the source contract says otherwise; keep them valid for the complete operation and never assume null is accepted.
