Android Kernel Development Scheduler TeamScheduler team is responsible for maintaining and implementing core linux scheduler features unique to Qualcomm which optimize power and performance of the chipset (frequency control, task placement, load balancing, etc).- Implemented key scheduler features on Snapdragon Gen 1 (SM8450), 2 (SM8550), and 3 (SM8650)- Worked closely with Google to implement features and trace-hooks for Qualcomm features- Developed tools for low-level cache and memory performance evaluation for new chipsets (SM8750)While being responsible for addressing many scheduler issues and features across Qualcomm's dedicated scheduler code, was responsible for a feature known as core-control. This feature allows the kernel to decide which cores should be used at a given moment in time, and schedule tasks appropriately on cpus, avoiding those that are "halted" by core-control. It does this automatically, and in orders of magnitude less time than equivalent hot-plug operations, essentially providing a tuning for ensuring cores can enter a low-power mode quickly, or be available quickly for new load execution.During ongoing stability testing and product validation, addressed hard to solve defects related to scheduler behavior. Towards the tail-end of each of these SOCs, worked to satisfy needs of customers and in general prepare the product for customer sampling.Linux kernel development for cutting edge chipsets. Requires a range of duties, from modifying kernel source to improve performance, finding/fixing bugs in kernel source, chipset bring up, benchmark verification of scheduler changes, and review of kernel modifications from team members. Includes developing, submitting and getting approval for source changes made to upstream. Worked with linux kernels 5.4,5.10,5.15 and beyond.

My primary focus during this time was on Android Devices. For all of 2009, those devices were explicitly "Google Experience" devices. While I contributed to the Droid effort, my primary responsibility was to ensure that Milestone (Droid for rest of world) launched with equivalent or better quality as Droid, immediately following the launch of Droid in the United States. In this we were successful. To help to achieve that, I wrote tools and systems that aided in the tracking and analysis of critical defects from all components of the software. This, paired with existing Motorola statistical systems, enabled us to approach issues well aware of the severity of the failures, enabling us to assign severity and priority to issues, attacking the worst failures first, optimizing the development cycle.Later in this period I continued with this theme, but on Motorola Experience devices. There is a great deal more work to be done in this area, because the majority of the applications side effort is left to Motorola, not Google. This year we have significantly improved our capabilities, automatically logging failures from devices, including full logs, enabling the engineers to immediately have "logcat" and kernel logs of a severe failure. During this time we were constantly seeking to expand our capabilities, to ensure that we have the absolute best chance at getting the information we need to solve an issue, as soon as we even know about the issue. In addition to being responsible for this development, I spent a good deal of the 2011/2012 years using this data to actually solve failures. Specifically, JAVA Applications failures, our primary source of failures (in terms of quantity) on the device, but also some kernel and modem failures. This information is also used to drive other teams, to ensure that they too, pursue the worst issues on the device in their respective areas (kernel, modem, framework).

One of my roles during this period was to develop ciritcal linux tools for embedded linux applications. The tool was required to produce a valid stack trace with useful, function-level information, despite debug information being removed from the product and severely truncated core-files. This tool proved sufficient for solving almost all crashes present in a linux application, even when that crash came from a dynamically loaded library. These tools were made available to the general engineering population.Additionally, my role during this time was to track down and solve every possible linux application crash I could find personally, as well as assist other engineers and my team members, in solving the crashes they were experiencing on their applications. Typically this would involve the tools I had developed.The team-goals were to ship the highest quality product in the time allowed, using every and all means to achieve those goals.

During this period I was working strictly with a micro-kernel, virtualized embedded Linux platform. My recent work has been to drivers on the real-time and Linux kerenel sides, most specifically related to nand flash interfacing, flash partition management, and bad block management.In addition, I've been mentoring my employees with their efforts, most directly related to their work in Multimedia and USB/AT Command Parsing.Finally, I've been loosely managing a project related to UMTS development, with specific exposure to the MSM6290 Chipset from Qualcomm. This project is less strictly controlled, as we feel out the viability of the intended product. (Update: this UMTS product was cancelled, as we determined the hardware design was insufficient to meet product goals)

During this time my role continued as before, but included additional job requirements beyond engineering. I had a small staff I mentor, assign tasks, and grade on a yearly basis. This type of role enhances my engineering role, enabling me to always be involved in the daily activities of product development, while building an understanding of the business aspects of mobile devices and consumer electronics.In addition, I am a member of the staff responsible for driving the business needs and goals of the organization.
