* All stats completion are indicated by incrementing stats progress syncpoint
* a number of times = <num-stats-enabled>.
*
* If the flag CAPTURE_FLAG_ISP_STATUS_REPORT_ENABLE is set in the isp
* capture descriptor, RTCPU will store the capture status into status field
* of the descriptor. RTCPU will also send a CAPTURE_ISP_STATUS_IND
* message to indicate that capture has completed.
*
* If the flag CAPTURE_FLAG_ISP_ERROR_REPORT_ENABLE is set, RTCPU will send a

/**
* Send new isp_program request on a capture ivc channel.
*
* The request contains channel identifier and the program sequence
* number (ring-buffer index).
* The actual programming details is stored in isp_program
* descriptor, which includes the offset to isp_program
* buffer (which has PB1 containing ISP HW settings), sequence,
* settings-id, activation-flags, isp_program buffer size, iova's
* of ISP PB1 and isp_program status written by RTCPU.
*
* NvCapture UMD allocates the pool of isp_program descriptors in setup call,
* where each isp_pgram_descriptor is followed by corresponding isp_program
* buffer (ATOM aligned).
* The ring-buffer (pool) would look like below:
*
* [isp_prog_desc][isp_program][isp_prog_desc][isp_program][isp_prog_desc]...
*
* The isp_program_descriptor with buffer_index=N can be located within
* the ring buffer as follows:
*
* isp_program_descriptor *desc = programs + buffer_index * program_size;
*
* Note, program_size = sizeof (isp_program_descriptor) + sizeof (isp_program).
*
* NvISP fills these and submits the isp_program request to KMD which pins the
* PB and then does the in-place replacement with iova within
* isp_program_descriptor.
* KMD then sends the isp_program request to RTCPU over capture ivc channel.
*
* The sequence is the frame_id which tells RTCPU, that the given isp_program
* must be used from that frame_id onwards until UMD provides new one.
* So RTCPU will use the sequence field to select the correct isp_program from
* the isp_program descriptors' ring buffer for given frame request and will
* keep on using it for further frames until the new isp_program (desc) is
* provided to be used.
* RTCPU populates both matched isp_program (reads from isp program desc) and
* isp capture descriptor and forms single task descriptor for given frame
* request and feeds it to falcon, which further programs it to ISP.
*
* settings_id is unique id for isp_program, NvCapture and RTCPU will use
* the ring buffer array index as settings_id.
* It can also be used to select the correct isp_program for the given
* frame, in that case, UMD writes this unique settings_id to sensor's
* scratch register, and sensor will send back it as part of embedded data,
* when the given settings/gains are applied on that particular frame
* coming from sensor.
*
* RTCPU reads this settings_id back from embedded data and uses it to select
* the corresponding isp_program from the isp_program desc ring buffer.
* The activation_flags tells the RTCPU which id (sequence or settings_id) to
* use to select correct isp_program for the given frame.
*
* As same isp_program can be used for multiple frames, it can not be freed
* when the frame capture is done. RTCPU will send a separate status
* indication CAPTURE_ISP_PROGRAM_STATUS_IND message to CCPEX to notify
* that the given isp_program is no longer in use and can be freed or reused.
* settings_id (ring-buffer index) field is used to uniquely identify the
* correct isp_program.
* RTCPU also writes the isp_program status in isp program descriptor.
