Kernel and Driver Development Services

We define the supported kernel versions at the start of the project. For Linux driver development, we isolate version-specific API differences and use conditional code where needed. We build and test the driver against every target kernel version, adapting the code when kernel APIs change. For out-of-tree Linux kernel drivers, we maintain the source and build configuration so the module can be rebuilt for each supported kernel release.

Yes. We can take over an unfinished driver project at any stage. We start by reviewing the existing source code, documentation, hardware specifications, build environment, and known issues. Then we assess the current implementation, identify gaps and problem areas, and define what is needed to complete the project. Depending on its condition, our engineers can fix defects, refactor or extend the existing code, port the driver to another platform or OS version, and complete integration and testing.

We start by reproducing the failure and collecting kernel logs, crash dumps, stack traces, and relevant hardware state. Depending on the platform, we use tools such as WinDbg and Driver Verifier on Windows or kdump, ftrace, and KGDB on Linux. We analyze execution paths, interrupt handling, memory access, locking, and timing to isolate race conditions, deadlocks, memory corruption, and driver faults. Once we fix the root cause, we run regression and stress tests to make sure the issue does not recur under load.

Yes. We develop drivers for real-time and latency-sensitive systems where predictable response times are critical. Our Linux kernel driver development can support PREEMPT_RT environments, optimized interrupt handling, efficient DMA transfers, and synchronization mechanisms that help reduce latency and jitter. We also profile and test driver behavior under realistic system loads to identify latency spikes and verify performance against the project’s timing requirements on the target hardware.

Not every device needs a custom driver. If your hardware uses a standard device class and the target OS already includes a compatible driver, no additional driver programming may be required. Custom driver development is usually needed for tailor-made hardware, vendor-specific protocols or peripherals, or functionality that existing drivers do not support. We can review your hardware, interfaces, and target OS and determine whether a new driver is required or an existing one can be used or adapted.

We typically need device documentation, relevant schematics, interface or protocol specifications, and access to the target hardware. We also need the target OS and version, hardware platform, and required driver functionality. For Linux kernel driver development, the kernel configuration, BSP, and existing driver or platform source code may also be useful. If some documentation or requirements are missing, we can analyze the hardware and identify the missing inputs during the initial technical assessment.

Yes. We develop custom OS modules and other low-level components when standard functionality does not meet the requirements of the hardware or application. This includes Linux kernel modules, device driver software, system services, and related system-level components for Linux, Windows, macOS, and Android. We can build a new component from scratch or modify and port existing code to support another OS or kernel version, hardware platform, or peripheral.
