    • Validate and debug device-tree or ACPI configurations for PCI host bridges and endpoints.
    • Kernel and Firmware Interaction:
    • Collaborate with firmware/bootloader teams for correct BAR, MSI/MSI-X, and IOMMU configurations.
    • Work closely with architecture teams to support secure boot and DMA protection for PCI devices.
    • Performance and Power Optimization:
    • Analyze PCI bandwidth, latency, and power bottlenecks.
    • Implement ASPM, LTR, and other low-power states in compliance with PCIe specs.
    • Debugging and Issue Resolution:
    • Use Linux tools (lspci, setpci, tracepoints, ftrace, perf, etc.) and oscilloscopes/analyzers for low-level debugging.
    • Root-cause platform PCI failures and compatibility issues across hardware and kernel versions.
    • Upstream and Compliance:
    • Contribute patches upstream to the Linux kernel PCI subsystem.
    • Ensure compliance with PCI-SIG and Linux kernel community best practices.
    • Cross-Team Collaboration
  • Interface with SoC, BIOS/UEFI, board, and validation teams to ensure robust PCIe device support across platforms.

Work Experience

    • Deep understanding of Linux kernel internals, especially drivers/pci and subsystems like hot plug, MSI, IOMMU, DMA API.
    • Hands-on experience with PCIe Gen3/Gen4/Gen5 devices and related PHY bring-up issues.
    • Familiarity with ARM64 and x86 architectures, DT/ACPI handling for PCI devices.
    • Proficient in C programming, Linux kernel debugging (GDB, crash dumps), and tools like dmesg, lspci, pcie_check.
    • Expertise in power management (runtime, suspend/resume flows) for PCI devices.
    • Experience with Secure Boot, TrustZone, and virtualization passthrough (VFIO/SR-IOV) for PCIe devices is a strong plus.
    • Experience using Yocto, Buildroot, or other embedded Linux build systems.
