函数名称:q_matrix_free - Free allocated interrupt in the matrix*@m: Matrix pointer*@cpu: Which CPU map needs be updated*@bit: The bit to remove*@managed: If true, the interrupt is managed and not accounted* as available.
函数原型:void irq_matrix_free(struct irq_matrix *m, unsigned int cpu, unsigned int bit, bool managed)
返回类型:void
参数:
类型 | 参数 | 名称 |
---|---|---|
struct irq_matrix * | m | |
unsigned int | cpu | |
unsigned int | bit | |
bool | managed |
414 | cm等于per_cpu_ptr(maps, cpu) |
416 | 如果WARN_ON_ONCE(bit < alloc_start || bit >= alloc_end)则返回 |
420 | allocated自减 |
421 | 如果managed则managed_allocated自减 |
424 | 如果online则total_allocated自减 |
427 | 如果非managed则 |
428 | available自加 |
429 | 如果online则global_available自加 |
