libnvme_get_log_dynamic_chunk(9)

NAME
libnvme_get_log_dynamic_chunk - Get log page data with dynamic chunk size

SYNOPSIS
int libnvme_get_log_dynamic_chunk (struct libnvme_transport_handle *hdl , struct libnvme_passthru_cmd *cmd , bool rae , __u32 xfer_len );

ARGUMENTS

hdl Transport handle

cmd Passthru command

rae Retain asynchronous events

xfer_len
    Initial max log transfer size per request to split the total. Dynamically divide chunk size by 2 when any error is encountered, and retry until the chunk size is down to 4k or the command succeeds. This allows for successful retrieval of log pages that may have a smaller maximum transfer size than the controller's MDTS value, without requiring the caller to know the optimal chunk size in advance.

RETURN
0 on success, the nvme command status if a response was received (see enum nvme_status_field) or a negative error otherwise.
