@itrue The issue is described on https://wiki.ubuntu.com/RISC-V/PolarFire%20SoC%20FPGA%20Icicle%20Kit.
Upstream kernel patches are still under discussion. Reopening the issue does not help unless there are upstream patches that we can merge into our kernel. Here is the latest work on cleaning up the code: [PATCH v9 0/22] Refactoring Microchip PCIe driver and add StarFive PCIe https://lore.kernel.org/linux-riscv/20231020104341.63157-1-minda.c...@starfivetech.com/ -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-riscv in Ubuntu. https://bugs.launchpad.net/bugs/1989566 Title: [FFe] PolarFire Icicle Kit: enable PCIe support Status in linux-riscv package in Ubuntu: Confirmed Bug description: The PolarFire Icicle Kit provides a PCIe slot. With our 5.19 kernel it is not usable.
