# Check Cloud AI accelerator card health and functionality Use the following examples to check the card health and functionality. 1. Check PCIe enumeration. lspci | grep Qualcomm 01:00.0 Unassigned class [ff00]: Qualcomm Device a100 Copy to clipboard A PCIe enumeration failure can indicate an unsecure connection. Try re-inserting the card, or troubleshoot with a different PCIe card. 2. Check device nodes. ls /dev/mhi* mhi0_QAIC_DIAG mhi1_QAIC_DIAG mhi2_QAIC_DIAG mhi0_QAIC_QDSS mhi1_QAIC_QDSS mhi2_QAIC_QDSS Copy to clipboard - For every card, `QAIC_DIAG`, `AIC_QDSS` nodes are created. - If `mhi*` folders don’t exist, check the MSI settings in the UEFI/BIOS setup. 3. Check the card health and status with `qaic-util`. sudo /opt/qti-aic/tools/qaic-util -q | grep -e Status -e QID Copy to clipboard This example shows a system with four Cloud AI SoCs (each card has one or more SoCs based on the SKU). > > > - `Status: Ready` indicates the card(s) is in good health. > - `Status: Error` indicates the respective card(s) hasn’t booted up completely. > - Card could still be booting. Wait for a few minutes and retry the previous command. > - Card error could be due to several reasons: unsupported OS/Platform or secure boot. QID 0 Status:Ready QID 1 Status:Ready QID 2 Status:Ready QID 3 Status:Ready Copy to clipboard 4. Run a test inference workload with the `qaic-runner` CLI to check hardware and software functionality. sudo /opt/qti-aic/exec/qaic-runner -t /opt/qti-aic/test-data/aic100/v2/1nsp/1nsp-conv-hmx/ -a 14 -n 5000 -d 0 Copy to clipboard Test options include the following: > > > - `-a` edit value based on number of NSPs in a specified QAIC device ID (QID). > - `-d` specify QID to run the workload on. Expected result: Input file: /opt/qti-aic/test-data/aic100/v2/1nsp/1nsp-conv-hmx//user_idx0_in.bin ---- Stats ---- InferenceCnt 5000 TotalDuration 15094us BatchSize 1 Inf/Sec 331257.453 Copy to clipboard A positive value for `Inf/Sec` indicates that the hardware and software are functioning correctly. The `Inf/Sec` reported depends on `-a` specified in the command.
