Developers Guide¶
QEP DPDK driver is implemented as an Ethernet poll mode driver in DPDK v18.11. It supports streaming interface to QDMA.
Driver interfaces and callbacks¶
The Driver registers two driver interfaces (net_qdma for PFs and net_qdma_vf for VFs) with DPDK RTE.
However, QEP supports only PF interface.
Below eth_dev_ops callbacks are implemented by the driver interface of the DPDK driver.
static struct eth_dev_ops qdma_eth_dev_ops = {
.dev_configure = qdma_dev_configure,
.dev_infos_get = qdma_dev_infos_get,
.dev_start = qdma_dev_start,
.dev_stop = qdma_dev_stop,
.dev_close = qdma_dev_close,
.dev_reset = qdma_dev_reset,
.link_update = qdma_dev_link_update,
.dev_set_link_up = qep_dev_set_link_up,
.dev_set_link_down = qep_dev_set_link_down,
.rx_queue_setup = qdma_dev_rx_queue_setup,
.tx_queue_setup = qdma_dev_tx_queue_setup,
.rx_queue_release = qdma_dev_rx_queue_release,
.tx_queue_release = qdma_dev_tx_queue_release,
.rx_queue_start = qdma_dev_rx_queue_start,
.rx_queue_stop = qdma_dev_rx_queue_stop,
.tx_queue_start = qdma_dev_tx_queue_start,
.tx_queue_stop = qdma_dev_tx_queue_stop,
.rx_queue_count = qdma_dev_rx_queue_count,
.rx_descriptor_status = qdma_dev_rx_descriptor_status,
.tx_descriptor_status = qdma_dev_tx_descriptor_status,
.tx_done_cleanup = qdma_dev_tx_done_cleanup,
.queue_stats_mapping_set = qdma_dev_queue_stats_mapping,
.get_reg = qdma_dev_get_regs,
.stats_get = qdma_dev_stats_get,
.stats_reset = qdma_dev_stats_reset,
.xstats_get_names = qep_dev_xstats_get_names,
.xstats_get_names_by_id = qep_dev_xstats_get_names_by_id,
.xstats_get = qep_dev_xstats_get,
.xstats_get_by_id = qep_dev_xstats_get_by_id,
.xstats_reset = qep_dev_xstats_reset,
.mtu_set = qdma_dev_mtu_set,
.rxq_info_get = qep_dev_rxq_info_get,
.txq_info_get = qep_dev_txq_info_get,
.dev_supported_ptypes_get = qep_dev_supported_ptypes_get,
.reta_query = qep_dev_rss_reta_query,
.reta_update = qep_dev_rss_reta_update,
.rss_hash_conf_get = qep_dev_rss_conf_get,
.filter_ctrl = qep_filter_ctrl,
};
In addition, the DPDK driver also implements below rte_flow_ops for RSS configuration.
const struct rte_flow_ops qep_flow_ops = {
.validate = qep_flow_validate,
.create = qep_flow_create,
.destroy = qep_flow_destroy,
.flush = qep_flow_flush,
};
Below sequence diagram depicts the application call flow to the driver callbacks and their high level operations.
Implementation details of the callback APIs is described further in
Additional interfaces are exported by the driver for QDMA configuration. These new interfaces are described in
DMA Hardware Error Monitoring¶
There are various causes for errors in QDMA IP e.g. descriptor errors, DMA engine errors, etc. If the errors are enabled by SW, QDMA logs the status of error in the respective global status registers.
DPDK driver executes a poll thread qdma_check_errors() every 1 second to check the error status and log the type of HW error occured on the console.
DPDK Driver debug¶
DPDK driver provides APIs rte_pmd_qep_dbg_regdump(), rte_pmd_qep_dbg_qinfo(),
rte_pmd_qep_dbg_qdesc(), rte_pmd_qep_dbg_stmninfo(), rte_pmd_qep_dbg_lbusinfo() to dump debug information.
Below debug information can be dumped using these API
- Dump QDMA registers
- Dump queue contexts for the given queue id
- Dump software information for the given queue id
- Dump the specified descriptor ring of the given queue id
- Dump STM-N status and statistics registers
- Dump LBUS status and statistics registers
User application can call these API to dump the required debug information.
dpdk-procinfo¶
Xilinx provides patch for dpdk-procinfo application to dump debug information using these APIs. This application should be run as a secondary application in a separate shell to the primary application. The patch adds/updates following option in dpdk-procinfo application.
-g: To display QDMA configuration registers
-q <queue id>: To Select queue
—qinfo: To display QDMA queue context and SW structure
–desc-dump {rx | tx | cmpt}: To dump QDMA queue descriptors
—xstats: To display extended port statistics
–stmn: To print STM-N and LBUS debug information
Sample execution command and output is given below
