Linux Device Driver Developer

7 hours ago

Bengaluru, Karnataka, India Global Technologies Full time ₹ 12,00,000 - ₹ 36,00,000 per year

Responsibilities :


- 5+ years of experience with Linux device driver development, preferably with a focus on PCIe devices.

Open Source Contribution :

Experience contributing to the Linux kernel or relevant open-source projects is highly valued.

Expertise in C Language :


- Mastery of C for low-level, performance-sensitive code, including bitwise operations, memory management, pointer arithmetic, and data structure optimization.

Familiarity with C++ :


- Advantageous for certain projects, though most Linux kernel drivers are written in C. Understanding object-oriented concepts in a C context is also helpful.

Deep Understanding of Linux Kernel Architecture :

- Familiarity with kernel space versus user space, kernel modules, device driver concepts, and memory management.

Kernel Module Development :

- Experience writing loadable kernel modules (LKMs) and integrating them with the Linux build system.

Debugging and Profiling :

- Proficiency with debugging tools such as kgdb, ftrace, perf, dmesg, and sysfs interfaces to troubleshoot and optimize drivers.

Comprehensive Understanding of PCIe Specification :

- Knowledge of the PCIe standard, including enumeration, configuration space, BARs (Base Address Registers), MSI/MSI-X interrupts, and bus mastering.

Device Datasheet Interpretation :

- Ability to read and interpret PCIe device hardware documentation, including register maps, timing requirements, and signaling protocols.

Interfacing with Firmware/BIOS :

- Understanding how PCIe devices are initialized during system boot, and the mechanisms by which firmware and BIOS communicate with hardware.

Device Driver Development Lifecycle :

Probing and Initialization :

- Experience writing probe() and remove() functions to handle device enumeration and teardown.

Resource Management :

- Skills in managing memory and hardware resources, including DMA (Direct Memory Access), I/O regions, and interrupt lines.

Interrupt Handling :

- Ability to write efficient and robust interrupt handlers, using mechanisms such as bottom halves, tasklets, work queues, and threaded interrupts.

Power Management :

- Familiarity with runtime and system power management interfaces, including suspend/resume operations.

Concurrency and Synchronization :

- Understanding race conditions, atomic operations, spinlocks, mutexes, and semaphores in a preemptible kernel environment.

Bachelors or Masters Degree :

- In Computer Science, Electrical or Computer Engineering, or a related technical field.

Desirable Additional Qualifications :

Knowledge of Other Operating Systems :

- Familiarity with Windows, FreeBSD or RTOS driver models for cross-platform development.

Experience with FPGA, SoC, or Custom Hardware :

- Useful for teams working on nonstandard PCIe endpoints or accelerators.
