About

Vivek Kumar is a highly skilled Software Engineer with over 7 years of experience in Linux-Kernel and Device drivers. He is currently working as a Senior Lead Engineer at Qualcomm, where he is responsible for developing new features on downstream core Linux kernel/device drivers. He has a very good understanding of complex new generation SoCs with multi-cluster systems and remote processors sharing a common DDR, cache-coherent-interconnects. Vivek has rich experience in SoC/Board bring-up, creating new device trees for new SoCs, and adding required driver support for new peripherals. Vivek is experienced in updating LTS kernel distributions of ongoing product lines (3.18, 4.4, 4.14, 5.4 kernel versions) and maintaining, fixing, and customizing kernel code across multiple areas as per requirement. He has a very good understanding of DMA-IOMMU, DMA-buf-ION framework, various memory allocators (Buddy/Slab/kmem-cache/CMA/reserved memory allocation, etc), ARM-SMMUv2 driver, Hibernation on Linux kernel, SoC Boot time optimization, GPIO & IRQ framework in Linux, and dealing with kernel crashes reported internally and by customers. Vivek has experience in doing effective usage of Jtag, Crash-utility, ram dump simulators and parsers, Kernel tracing, and various debug-based Kernel configs. He has a good understanding of various kernel internals like scheduler, memory management, synchronization mechanisms, CPUfreq scaling, suspend to ram, Linux power management, device model, and experience with shared memory model-drivers (SMEM), memory shared with multiple remote-procs, to interact and communicate. Vivek has worked on a Virtual Linux OS, writing few para-virtualized drivers which interact with backend hypervisor. He has rich experience with ARMv7/v8 architecture-based 32bit/64bit Application processors paired with ARM-MMU, ARM-SMMUv2, ARM-GICv3, and maintaining LK/UFEI Compliant bootloaders for Qualcomm's various Automotive Products. He has a good understanding of SoC boot flow. Vivek holds a Bachelor’s Degree in Electrical and Electronics Engineering from the National Institute of Technology Calicut. He is a highly skilled software engineer with expertise in backend development.
