Linux Kernel Development and Testing

• predominantly tests the QCOM specific kernel enhancements and develops test drivers to validate the drivers
• Primarily worked on scheduler, Apps bootloader and Memory driver testing
• Developed/Designed various testcases for scheduler to validate the ARM BigLittle Heterogenous CPU architecture
• Developed/Designed various linux memory features to improve memory optimization features
• Designed and developed low level micro benchmarks to test CPUSS efficiency
• Developed Fuzzers to performed fuzz drivers using ioctls
• Automated most of the test drivers using python
• Also worked on kernel continuous integration , to enable job triggers for Dev changes by using change based testing

System Stability Testing

• Involved in stability testing on various Qualcomm SOC’s ( A family . B –family & Bear ) on different Android Operating systems
• Involved in the development of scripts USB & NO-USB stability tests
• Responsible for publishing Daily, weekly and monthly reports to program & dev managements.
• Involved in collaborating with various tech teams in root causing HW centric memory leak, memory corruption issues.
• Worked as stability POC for 8926/8939 MSM’s , ensured that issues are being update to scrum on daily basis and metrics are met for the releases

System Stability Test Automation and Testing on Qcom Chipsets

• Developed Concurrency stability suites like Multimedia stress , Application process stress and Hardware Stress
• All these suites development required through understanding on Multimedia IP , CPU IP and complete SOC level usecases
• Collaborated with various tech teams in understanding new features that runs on these IP's to devise the usecases
• Wrote Code using Python, shell scripting
• At times, used to report the stability issues to relevant tech by doing the initial analysis
• Good understanding on debug tools like Lauterbach Jtag to dump the system registers , Kernel debugging using KGDB
