Hallo,
We are developing a FPGA board connected to a Fedora 15 PC host over PCIe. Right now, in the implementation and debug phase, I often need to power off and
power on the device or try different boards. This causes a problem with the Fedora 15 running on the AMD PC.
Typically the PC is booted when I need to insert the device under test. As expected, the Linux doesn't find the device and the software app cannot talk to it.
* If I do "lspci -v" then it does not list our device.
* Then I execute "echo 1 > /sys/bus/pci/rescan"
* Now "lspci -v" lists our device.
* But our software returns : 0xFFFFFFFF

It looks that 'rescan' is not enough to handle cases like this? Or, is there a
way to "insert" the FPGAs later after the kernel boots up?
Many thanks in advance,

The pciehp automatically scans the bus on presence changed event (e.g. board is pluged in) if the hot-plug controller supports surprise removal. Otherwise, you need to power on slot explicitly by "echo 1 > /sys/bus/pci/slots/XXX/power". So one possibility is that your controller doesn't support surprise removal. We can check it by looking at the pciehp's debug output. Can you send whole dmesg output?

* Re: PCIe can not rescan for new PCIe device ( FPGA board ) 2011-10-12 8:35 ` Abdelghani Ouchabane @ 2011-10-13 12:50 ` Kenji Kaneshige 2011-10-14 9:40 ` Abdelghani Ouchabane 0 siblings, 1 reply; 17+ messages in thread From: Kenji Kaneshige @ 2011-10-13 12:50 UTC (permalink / raw) To: Abdelghani Ouchabane; +Cc: Bjorn Helgaas, linux-kernel, linux-pci Thank you for the information. Though I don't have any good news for you, I think as follows based on the info. - There are two hot-plug capable PCIe slots on your machine. - But, it seems you are using fakephp driver, not pciehp (is that correct?). The fakephp cannot handle hot-plug event such as presence change event on the slot. This is why the bus is not scanned automatically. - Unfortunately, the bus would not be scanned automatically even if you use pciehp. As I told you in the previous email, current pciehp don't scan the bus automatically only if the slot is hot-plug surprise capable. According to the lspci output, your hotplug controller is not hot-plug surprise capable. - I don't think pciehp solve invalid register read problem. According to the lspci output, power controller capability isn't present on your hotplug controller. On such environment, pciehp driver does almost the same thing as fakephp does (just scan the bus/remove the pci device data structure) except hot-plug event handling. But it's worth whole trying pciehp. By the way, have you tried acpiphp? It might help you.

Fakephp driver doesn't have any corresponding hotplug controller (hardware).

Some platform only allows acpiphp, but doesn't allow PCIe native hotplug driver (like pciehp). The 'pciehp_force' specified your environment is to load pciehp forcibly on such platform. So I thought acpiphp might solve your problem.

I don't think it's likely to be a BIOS problem.

I will give you more details: Our old systems are based on the Congatec COM Express conga-B945 ( based on the Intel Mobile 945GME chipset ), and we are using a GPO line to control the power switch on the FPGA board that is connected using PCIe line 0. On the B945 this line is high by default during the boot ( The FPGA board gets powered while the system boots "this is the desired behaviour" ). But now we are working to use the new Congatec COM Express conga-BAF ( based on the AMD Embedded G-Series Processors ), The GPO line is zero by default during the boot. So, after the system boots, we power the FPGA board on, but unfortunately the system can not access the FPGA registers. We are trying to solve this issue and get the FPGA board works without changing the hardware. > The BIOS left the bridge to bus 02 with all windows disabled, but > Linux allocated and enabled the windows as above, and we assigned BARs > of device 02:00.0 inside those windows.

Thanks for the details. If I understand correctly: A - fails (card not present at power-on, added later) B - works (card always present) C - works (card present at power-on, later removed and re-added, requires manual rescan) I see this note in section 9.4.8 (BIOS setup) of the conga-BAF User's Guide: Note: Unless the hotplug support for this port is enabled as well, an unpopulated port will still be disabled if no PCI Express device is connected. If you don't have hotplug enabled in the BIOS setup, it sounds like it might result in the behavior you're seeing. Do you have that enabled?

Among the fix is: _BBRAR009 to BBRAR110:_ 2. Enabled PCIExpress / ExpressCard basic hotplug support. Enabled event handling support. Now after the manual rescan my FPGA board gets detect correctly and I can access its registers in the correct way. Many thanks for all your supports.
