PCIE MSIX issue

[Alex_mjl]

Hi NXP team,

    The platform I'm using is S32G274A-RDB2 and the SDK version is BSP38.0.

    I am currently using a Realtek 9071CP switch chip, which is a device with a PCIe interface. I connect to it using PCIE1.

    The current problem is that it can be recognized by pcie,  but loading its driver will cause the kernel crash.

    The process of crash is:

                       pci_enable_msix_range

                       |->__pci_enable_msix_range

                            |->__pci_enable_msix

                                |->pci_msix_vec_count

                                    |->pci_read_config_word

    The detailed crash log is as attached 'crash.txt'.

    By the way, the configuration of PCIE in U-Boot is as follows: hwconfig=pcie0:mode=pcie,clock=ext;pcie1:mode=pcie,clock=ext

hi,Alex_mjl

Thank you for contacting us.

Do you check whether the Realtek 9071CP supports the MSI-X? In addition, could you share the crash.txt file, I can not find the file.

Hi Joey_z,

    I have re-uploaded the log of crash.

    Realtek 9071CP supports msi-x. I have verified this driver on other platforms.

hi,Alex_mjl

According to your information, the rtase.ko module did encounter problems during the loading process. The error occurred when the driver attempted to initialize. Please check whether there is a conflict in the memory used for driver initialization.
