Installation Checklist¶

First, check Hardware requirements and supported operating environments.

Local Server Installation¶

Set up Linux server/workstation environment (Pre-requisites)
- Enable 32 message signaled interrupts (MSI) in UEFI/BIOS setup (MSI instructions)
Install Platform and Apps SDKs (Cloud AI SDK)
Tip: To run Platform SDK tools without superuser (sudo) privilege, add yourself to the qaic group.
```
sudo usermod -aG qaic $USER
```
- Log in again for the changes to take effect, or run ‘newgrp qaic’.

Verify Card Health/Function¶

Check PCIe enumeration:
```
$ lspci | grep Qualcomm
01:00.0 Unassigned class [ff00]: Qualcomm Device a100
```
- A PCIe enumeration failure may indicate an unsecure connection. Try re-inserting the card, or troubleshoot with a different PCIe card.
Check device nodes:
```
ls /dev/mhi*
/dev/mhi0_QAIC_DIAG  /dev/mhi0_QAIC_TIMESYNC /dev/mhi0_QAIC_QDSS /dev/mhi1_QAIC_DIAG
```
- For every card, QAIC_DIAG, QAIC_TIMESYNC, QAIC_QDSS and QAIC_DIAG nodes are created.
- If mhi* folders do not exist, double-check the MSI settings in UEFI/BIOS setup
Check card health and status with qaic-util
```
sudo /opt/qti-aic/tools/qaic-util -q | grep -e Status -e QID

    QID 0
      Status:Ready
    QID 1
      Status:Ready
    QID 2
      Status:Ready
    QID 3
      Status:Ready
```
- ‘Status: Ready’ indicates card(s) is in good health. Shown here are a system with 4 Cloud AI SoCs (Each card may have one or more SoCs based on the SKU).
- ‘Status: Error’ indicates the respective card(s) has not booted up completely.
  - Card could still be booting. Wait for a few mins and retry above command.
  - Card error could be due to several reasons - unsupported OS/Platform, secure boot etc.
Run a test inference workload with qaic-runner CLI to sanity check HW/SW function. Example:
```
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

Input file: /opt/qti-aic/test-data/aic100/v2/1nsp/1nsp-conv-hmx//user_idx0_in.bin
---- Stats ----
InferenceCnt 5000 TotalDuration 17598us BatchSize 1 Inf/Sec 284123.196
```
- -d specify QID to run the workload on.
- -a edit value based on no of NSPs in specified QID.
A positive Inf/Sec indicates HW/SW is functioning correctly. The Inf/Sec reported depends on -a specified in the command.

Virtual Machine Setup¶

Configure PCIe pass-through for the supported Hypervisor
Configure message signaled interrupts in UEFI/BIOS setup and Hypervisor
Install and configure Hypervisor
Configure and launch Virtual Machine instance with one of the supported Operating Systems and Pre-requisites
Install Cloud AI SDKs
Check Card Health/Function

Docker Setup¶

Install Platform SDK on host system or virtual machine (Cloud AI SDK)
Build Docker image and start the container (Docker)
