+ Instructions for using container to run test workload on Cloud AI 100
+
+ Cloud AI Container Setup
+
+ Pre-requisite:
+ 1) Install 1.20.2.5 (w/ the bug in question) Qaic FW and KMD from Linux
upstream or from Platform SDK.
+
+ Platform SDK Example:
+
+ Download and unzip Cloud AI Platform SDK from http://qpm.qualcomm.com,
+ then:
+
+ cd qaic-platform-sdk-1.20.4.0/x86_64/deb/deb
+
+ sudo apt update
+
+ sudo apt-get install -y ./qaic-fw_1.20.4.0.deb
+
+ sudo apt-get install -y ./qaic-kmd_1.20.4.0_all.deb
+
+ 2) Docker
+
+ Check for Docker:
+
+ sudo docker --version
+
+ If not found, then following instructions at
+ https://docs.docker.com/engine/install/ubuntu/ to install.
+
+ Start Container
+
+ This example starts the container with 2 SoCs and maps the current
+ working directory to /cloud-ai inside the container.
+
+ sudo docker run -it --workdir /cloud-ai --entrypoint /bin/bash
--network=host --name qaic-platform --mount
+ type=bind,source=${PWD},target=/cloud-ai --device=/dev/accel/accel0
--device=/dev/accel/accel1
+ ghcr.io/quic/cloud_ai_inference_ubuntu22:1.20.4.0
+
+ 3) Run Test
+
+ /opt/qti-aic/tools/qaic-diag -d 0 -m 0x4B 0x67 0x14 0x00 0x00
+
+ Diag Request:
+
+ 0x4b 0x67 0x14 0x0 0x0
+
+ Diag Response:
+
+ 0x4b 0x67 0x14 0x0 0x11 0x23 0x0
+
+ /opt/qti-aic/tools/qaic-diag -d 1 -m 0x4B 0x67 0x14 0x00 0x00
+
+ Diag Request:
+
+ 0x4b 0x67 0x14 0x0 0x0
+
+ Diag Response:
+
+ x4b 0x67 0x14 0x0 0x11 0x23 0x0
+
+ 4) Exiting the container
+
+ When test is completed, exit the container.
+
+ exit
+
+ sudo docker stop qaic-platform
+
+ sudo docker container rm qaic-platform
+
+ Test Steps:
+
+ - Install 1.20.2.6 FW (Step 1)
+ - Reboot the devices
+ - echo 1 > /sys/bus/mhi/devices/mhi0/soc_reset
+ - echo 1 > /sys/bus/mhi/devices/mhi1/soc_reset
+ OR
+ - /opt/qti-aic/tools/qaic-util -s
+ - Install Docker (Step 2)
+ - Start Container (Step 2)
+ - Run the workload (Step 3)
+
+ /opt/qti-aic/tools/qaic-diag -d 0 -m 0x4B 0x67 0x14 0x00 0x00
+
+ Diag Request:
+
+ 0x4b 0x67 0x14 0x0 0x0
+
+ Diag Response:
+
+ 0x4b 0x67 0x14 0x0 0x11 0x00 0x0
+
+ /opt/qti-aic/tools/qaic-diag -d 1 -m 0x4B 0x67 0x14 0x00 0x00
+
+ Diag Request:
+
+ 0x4b 0x67 0x14 0x0 0x0
+
+ Diag Response:
+
+ x4b 0x67 0x14 0x0 0x11 0x00 0x0
+
+ Temperature value is 0C in response
+
+ - Exit the container (Step 4)
+ - Install 1.20.2.7 FW (Step 1)
+ - Reboot the devices
+ - echo 1 > /sys/bus/mhi/devices/mhi0/soc_reset
+ - echo 1 > /sys/bus/mhi/devices/mhi1/soc_reset
+ OR
+ - /opt/qti-aic/tools/qaic-util -s
+ - Start Container (Step 2)
+ - Run the workload (Step 3)
+
+ /opt/qti-aic/tools/qaic-diag -d 0 -m 0x4B 0x67 0x14 0x00 0x00
+
+ Diag Request:
+
+ 0x4b 0x67 0x14 0x0 0x0
+
+ Diag Response:
+
+ 0x4b 0x67 0x14 0x0 0x11 0x23 0x0
+
+ /opt/qti-aic/tools/qaic-diag -d 1 -m 0x4B 0x67 0x14 0x00 0x00
+
+ Diag Request:
+
+ 0x4b 0x67 0x14 0x0 0x0
+
+ Diag Response:
+
+ x4b 0x67 0x14 0x0 0x11 0x23 0x0
+
+ Temperature value is SOME NON-ZERO number as it is 35C in this case. It
should hover between
+ 30-40C typically.
