Field Documentation

waitQ

Fvid2UtilsLinkListObj* CsitxDrv_InstBufManObj::waitQ

Buffers that are queued to SW but not sent to HW.

waitLlObj

Fvid2UtilsLinkListObj CsitxDrv_InstBufManObj::waitLlObj

Linked List object for waitQ.

txQObj

CsitxDrv_QueObj CsitxDrv_InstBufManObj::txQObj[(CSITX_TX_QUEUE_DEPTH_PER_CH *CSITX_NUM_CH)]

Transmit queue objects.

curFrmNum

uint32_t CsitxDrv_InstBufManObj::curFrmNum

Number of frames queued to current Queues of the each channels For J721E, this should be 1 at max due to CSITX IP limitation.

doneQ

Fvid2UtilsLinkListObj* CsitxDrv_InstBufManObj::doneQ

Queue object to put the processed output requests. This is kept common for all channels of a stream because frames can be given back to application in dequeue call without looping over each channel done queue.

doneLlObj

Fvid2UtilsLinkListObj CsitxDrv_InstBufManObj::doneLlObj

Linked List object for doneQ for all channels of each stream.
