How to get all pci devices

[EasonLian]

Hi all,

Environment: VMware ESXi 5.5.0 (VMKernel Release Build 1331820), ddk-5.5.0-1331820

1.Use command "lspci -v", I can find a lot of pci devices (more than 15);

2.Use the kernel api "pci_get_device" in my test driver code,that only print a little pci devices(only 4).

Part of codes follow list:

while ((pDev = pci_get_device_all(PCI_ANY_ID, PCI_ANY_ID, pDev)) != NULL)

{

    printk("find bus number %02x, vendor %04x, device %04x\n",

                        pDev->bus->number, pDev->vendor, pDev->device);

    continue;

    ...

}

Anybody can help me resolve this problem? Thank you!

Hi,

Just try with "pci_get_device" function.Link: https://www.kernel.org/doc/htmldocs/kernel-api/API-pci-get-device.html

In code,write as

struct pci_dev *pdev = NULL;

while((pdev=pci_get_device(PCI_ANY_ID,PCI_ANY_ID,pdev))!=NULL)

{

printk("Device found vendor_id=0x%x and device_id=0x%x...\n",pdev->vendor,pdev->device);

}

Hope it'll give all device.
