Name:lay_subbufs_consumed - update the buffer's sub-buffers-consumed count*@chan: the channel*@cpu: the cpu associated with the channel buffer to update*@subbufs_consumed: number of sub-buffers to add to current buf's count
Proto:void relay_subbufs_consumed(struct rchan *chan, unsigned int cpu, size_t subbufs_consumed)
Type:void
Parameter:
| Type | Parameter | Name |
|---|---|---|
| struct rchan * | chan | |
| unsigned int | cpu | |
| size_t | subbufs_consumed |
| 814 | If Not chan || cpu >= Places which use this should consider cpumask_var_t. Then Return |
| 817 | buf = per_cpu_ptr( per-cpu channel buffers , cpu) |
| 818 | If Not buf || subbufs_consumed > number of sub-buffers per buffer Then Return |
| 821 | If subbufs_consumed > count of sub-buffers produced - count of sub-buffers consumed Then count of sub-buffers consumed = count of sub-buffers produced |
| 823 | Else count of sub-buffers consumed += subbufs_consumed |
