libnvme_get_log_dynamic_chunk-libnvme32
Get log page data with dynamic chunk size
Usage
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.
