Subject: [PATCH v4 0/2] fpga: dfl: optional VSEC for start of dfl
Date: Thu,  3 Dec 2020 09:15:46 -0800	[thread overview]
Message-ID: <20201203171548.1538178-1-matthew.gerlach@linux.intel.com> (raw)

From: Matthew Gerlach <matthew.gerlach@linux.intel.com>

The start of a Device Feature List (DFL) is currently assumed to be at
Bar0/Offset 0 on the PCIe bus by drivers/fpga/dfl-pci.c.  This patchset
adds support for the start one or more DFLs to be specified in a
Vendor-Specific Capability (VSEC) structure in PCIe config space.  If no
such VSEC structure exists, then the start is assumed to be
Bar0/Offset 0 for backward compatibility.

  fpga: dfl-pci: locate DFLs by PCIe vendor specific capability
