Hi, I tried adding support for the newly added 'pcie_get_minimum_link' into the bnx2x driver, but found out the some of my devices started showing width x0. By adding debug prints, I've found out there were devices up the chain that Showed 0 when their PCI_EXP_LNKSTA was read by said function. However, when I tried looking via lspci the output claimed the width was x4. lspci -vt output: [0000:00]-+-00.0 Intel Corporation 5000P Chipset Memory Controller Hub +-02.0-[09-12]--+-00.0-[0a-11]--+-00.0-[0b-0d]-- +-01.0-[0e-10]--+-00.0 Broadcom Corporation NetXtreme II BCM57710 10-Gigabit PCIe [Everest] Where: 00:02.0 PCI bridge: Intel Corporation 5000 Series Chipset PCI Express x4 Port 2 (rev 93) 09:00.0 PCI bridge: Intel Corporation 6311ESB/6321ESB PCI Express Upstream Port (rev 01) 0a:01.0 PCI bridge: Intel Corporation 6311ESB/6321ESB PCI Express Downstream Port E2 (rev 01) 0e:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM57710 10-Gigabit PCIe [Everest] (rev 01) The output for "lspci -vvvv | grep LnkSta for all four is: LnkSta: Speed 2.5GT/s, Width x4, TrErr- Train- SlotClk+ DLActive- BWMgmt- ABWMgmt- But added prints inside the function's loop show: LnkSta 1041 [000e:00.00] LnkSta 0000 [000a:01.00] LnkSta 0000 [0009:00.00] LnkSta 3041 [0000:02.00] (PCI_EXP_LNKSTA value, bus->number, PCI_SLOT, PCI_FUNC) Thanks, Yuval -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
