Below the framework
Linux Kernel & Device Drivers
Most hard device problems live in the kernel. We write and maintain drivers, move boards onto newer kernels, bring vendor trees into GKI compliance, and chase the crashes and regressions that only reproduce on real hardware.
What this covers
Driver development
Platform and character drivers, V4L2 camera and video pipelines, ALSA and ASoC audio machine drivers, IIO sensors, input and touch, SPI/I2C/MMC controllers, PCIe and USB gadget, regulator and clock providers, DMA and interrupt handling.
GKI and KMI compliance
Splitting a monolithic vendor kernel into a Generic Kernel Image plus vendor modules, resolving KMI symbol breakage, and setting up the ABI monitoring that keeps a board upgradable instead of frozen on the kernel it shipped with.
Kernel migration and mainlining
Forward-porting board support across kernel versions, rebasing carried patches onto a new base, and preparing patches for upstream where mainlining reduces your long-term maintenance cost.
Debugging and performance
Kernel panics, deadlocks and memory corruption, ftrace and perf profiling, boot time reduction, power and thermal tuning, suspend/resume reliability, and the intermittent failures that only show up in a thermal chamber at 2am.
