From: Andy Moreton Date: Tue, 20 Feb 2018 07:33:48 +0000 (+0000) Subject: net/sfc/base: report memory BAR number X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e434de5d6b75047d2c1dc09d3661efa2d9ad080f;p=dpdk.git net/sfc/base: report memory BAR number On Medford and earlier controllers the BAR layout is: PF BAR 0: (32bit I/O) I/O mapped registers PF BAR 2: (64bit Mem) Memory mapped registers (VI aperture) PF BAR 4: (64bit Mem) MSI-X tables VF BAR 0: (64bit Mem) Memory mapped registers (VI aperture) VF BAR 2: (64bit Mem) MSI-X tables On Medford2, the layout is: PF/VF BAR 0: (64bit Mem) Memory mapped registers (VI aperture) PF/VF BAR 2: (64bit Mem) MSI-X tables Make the VI aperture BAR number available for drivers that need it. Remove EFX_MEM_BAR define as it it is not correct on all platforms.
