Core platform software development using Qualcomm processor and operating system.
1. Implemented code sharing technique for text regions shared between different process. This involves changes in process loader sequence and Virtual TLB handling in kernel. It also involves changes in various driver. This was mainly done to reduce memory usage if different process has same text region.
2. Used Qualcomm driver interface, which is used when secure process does things on behalf of non-secure process (where data structures is passed to secure process via QDI call).
3. Worked on issues on crash path handling during hardware exceptions, software exceptions, non-recoverable exceptions, process shutdown instead of full system crash in case of exceptions in a user process.
4. Enabled secure boot sequence to establish a trusted platform for secure applications.
5. Enable profiling to determine runtime of thread, runtime of system, CPU utilization of system.
6. Interrupt handling framework is changed to improve interrupt latency and to reduce memory footprint.
Development of safety processor BSP and SafeRTOS kernel using ARM cortexR52.
1. EL2/EL1 startup code, boot code, TCM memory, GIC interrupt framework, sleep and system call framework, EL2/EL1 MPU configurations, Timer, multicore boot flow, Exception handling.
2. Safe RTOS kernel was bought from third party vendor. Was communicating with third party vendor to integrate the kernel into Qualcomm bare metal environment. Has solved issues when integrating the kernel and was the POC for the safe RTOS issues.
