Hi Sylwester Nawrocki, I have some suggestion about s5p-fimc camera driver. As you know, FIMC have 32 ping-pong register(CIOYSA1~CIOYSA32) for output buffer in v310 chip. It is different from v210. It is not necessary to change address at ping-pong register. If request buffer number is 8, 8 buffer can be set at ping-pong register.
- active_buf_q / pending_buf_q The list_head pending_buf_q is not necessary for v310. Because, it is possible to set output buffer until 32. There is no case that request buffer number is over 32. So, I think pending_buf_q is not use in v310. Instead, it can be used active_buf_q. Of course, The use of active_buf_q may be different from the present. For intstance, ISR may be changed follow. a. Read FrameCnt_before(CISTATUS2) - This is for what is written buffer(index) just. b. Disable a proper bit of FrameCnt_Seq(CIFCNTSEQ) and send written buffer to done_list. .... I want to know how about your opinions. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
