[PATCH V4 1/2] pci: Add dev_flags bit to access VPD through function 0

From: Mark Rustad mark.d.rus...@intel.com Add a dev_flags bit, PCI_DEV_FLAGS_VPD_REF_F0, to access VPD through function 0 to provide VPD access on other functions. This is for hardware devices that provide copies of the same VPD capability registers in multiple functions. Because the kernel

[PATCH V4 2/2] pci: Add VPD quirk for Intel Ethernet devices

From: Mark Rustad mark.d.rus...@intel.com This quirk sets the PCI_DEV_FLAGS_VPD_REF_F0 flag on all Intel Ethernet device functions other than function 0. Signed-off-by: Mark Rustad mark.d.rus...@intel.com --- Changes in V3: - Added a multifunction device check --- drivers/pci/quirks.c |9

[PATCH V4 0/2] pci: Provide a flag to access VPD through function 0

Many multi-function devices provide shared registers in extended config space for accessing VPD. The behavior of these registers means that the state must be tracked and access locked correctly for accesses not to hang or worse. One way to meet these needs is to always perform the accesses through

Add a dev_flags bit, PCI_DEV_FLAGS_VPD_REF_F0, to access VPD through function 0 to provide VPD access on other functions. This solves concurrent access problems on many devices without changing the attributes exposed in sysfs. Never set this bit on function 0 or there will be an infinite
