Function xila_memory_flush_instruction_cache

#[no_mangle]
pub extern "C" fn xila_memory_flush_instruction_cache(
    _address: *mut c_void,
    _size: usize,
)

Flushes the instruction cache for a specific memory region.

This function invalidates the instruction cache for the specified memory region. This is necessary after modifying executable code to ensure the processor sees the updated instructions.

Safety

• The address must point to valid memory
• The memory region must not be accessed for execution during the flush operation
• The size should not exceed the actual allocated memory size

Parameters

• Address - Starting address of the memory region to flush
• Size - Size of the memory region in bytes

Examples

// After writing machine code to executable memory
void* code_ptr = xila_memory_allocate(NULL, 4096, 4096, XILA_MEMORY_CAPABILITIES_EXECUTE);
memcpy(code_ptr, machine_code, code_size);
xila_memory_flush_instruction_cache(code_ptr, code_size);

// Now safe to execute the code
((void(*)())code_ptr)();
