Multimedia/CDSP: Enhance fastrpc_test automation with CI-ready logging, argument parsing, and arch detection

[smuppand]

Key Enhancements

Robust environment sourcing

• Added reliable sourcing of init_env and functestlib.sh to ensure consistent runtime environment across test environments.

Argument parsing

• Supports --arch, --repeat, and --timeout options.
• Defaults to REPEAT=1, no timeout, and auto-detects architecture if not specified.

Architecture auto-detection

• Detects SoC ID from /sys/devices/soc0/soc_id and maps to known DSP architecture (v68, v73, v75) with fallback warning for unknown IDs.

Dependency checks

• Ensures fastrpc_test binary and required tools (e.g., grep) are available before execution.
• Falls back to script if stdbuf is unavailable for unbuffered output, with a warning if neither is found.

CI-debug friendly logging

• Added detailed logs for iteration count, SoC ID, detected architecture, and pass/fail counts per run.
• Captures and displays full output from each run to aid CI debugging.

Result file handling

• Writes standardized .res for CI parsers.
• Pass/fail determined by number of successful iterations vs total runs.

README.md update
Documented new script usage options, example runs, logging behavior, and CI integration notes.

Benefits

• Improved maintainability and portability across platforms.
• Better visibility in CI/CD pipelines with detailed logs and consistent result files.
• Flexible test execution with configurable parameters.

1. Currently the script is assuming that fastrpc_test is present in /usr/bin. Ideally, fastrpc_test should be moved or installed in /usr/share/bin/

2. Even after moving fastrpc_test and other related packages from /usr/share/bin to /usr/bin, we are seeing below issue.
   [INFO] 1970-01-07 06:22:35 - Buffering: stdbuf -oL -eL | Timeout: none | Arch: v75
   [INFO] 1970-01-07 06:22:35 - Running iter1/1 | start: 1970-01-07T06:22:35Z | cmd: fastrpc_test -d 3 -U 1 -t linux -a v75

3. fastrpc_test should be executed from the folder where fastrpc_test bin is present. As it will look for dependent packages in that folder only. For this reason only we implemented via stdbuf.

1. Currently the script is assuming that fastrpc_test is present in /usr/bin. Ideally, fastrpc_test should be moved or installed in /usr/share/bin/

The script has now been improved to automatically detect the required environment paths. Additionally, users can explicitly specify the directory where the fastrpc_test binary is located.

2. Even after moving fastrpc_test and other related packages from /usr/share/bin to /usr/bin, we are seeing below issue.
   [INFO] 1970-01-07 06:22:35 - Buffering: stdbuf -oL -eL | Timeout: none | Arch: v75

This issue is addressed now

3. fastrpc_test should be executed from the folder where fastrpc_test bin is present. As it will look for dependent packages in that folder only. For this reason only we implemented via stdbuf.

This also taken care.

Looks Good to Me
