About me

I am a Linux Kernel Engineer at AMD, working on the Secure Encrypted Virtualization technologies. Previously, I worked as a Kernel Developer at IBM's Linux Technology Center beginning, where I was part of the CPU team delivering upstream solutions for scheduling and energy management challenges affecting both the IBM POWER platform and the broader Linux community.

I earned my Master of Science in Computer Science from the University of Illinois Urbana-Champaign on a full-ride scholarship, and I hold a Bachelor of Technology from PES University.

Junk Code

Cloud and Containerization

  1. CPU namespace

    CPU isolation for containers. Provides consistency of sys/proc/cgroup fs interfaces. Also, improves security and performance. Linux Patches , Phoronix article , Linux Conf. Australia 2022

  2. Cgroup Control

    A simple script that helps in creating and controlling cgroups. Used when we want to avoid Docker overheads, and either do not wish to directly interact with the cgroup-tools like cgcreate,cgexec, etc; or this toolset is unavailable/unsupported. Github Gist

Energy Management

  1. Weighted TEO Governor

    Improvements to the current idle state governor's non deterministic event prediction algorithm. Uses a weighted history to create a probability distribution of the idle states rather the sliding window history. Linux Patches , LWN article

  2. CPU-idle latency self-test framework

    Estimate the wakeup latency caused by going into idle states. Hardware may certify certain latencies, however firmware and kernel overheads may exist. This will then lead idle governors making energy mangement decisions based on incorrect residency assumptions. Aim is to find significant deviations between advertised latency and residency values in the kernel space. Linux Patches

Debugging

  1. CPU-idle Verifier

    A processor may lose information in many registers based on how deep of an idle state it has gone. The platform saves and restores these registers on a wakeup. However, any inconsistency in restoring can lead to catastrophic failure which may not always crash the system upfront. A kernel debugging patch written for IBM POWER9 to verify the consistency of the registers before and after an idle state is evoked. Linux Patches

  2. CPU hotplug and Idle stress test

    Emulates long running behavior of usage of CPU power management in relatively short and intensive runs. Bash Script

  3. TimeBase Drift

    If the hardware timebase does not perform with monotonicity, the system fails in a cascading dominos of subsystem failures, making it incredibly difficult to pinpoint the root cause. A debug kernel module to identify timebase anomalies on the platform had been written to test any and all processors for such anomalies. Kernel module

I've had a lot of people ask me about college applications and how to write statements. So, sharing my statements out here so that it may help anybody who needs it.

Statement Of Purpose / Research statement

  1. PhD

    Even though I was accepted and eventually decided not to pursue a PhD, I figure it is still worthwhile to have it up here since writing a PhD statement varies a bit vs writing for a research based masters. PhD Statement of Purpose
