| Series | [net-next] cxgb4: Remove SGE_HOST_PAGE_SIZE dependency on page size | expand |
From: Arjun Vynipadath <arjun@chelsio.com> Date: Fri, 16 Nov 2018 09:15:42 +0530 > The SGE Host Page Size has nothing to do with the actual > Host Page Size. It's the SGE's BAR2 Doorbell/GTS Page Size > for interpreting the SGE Ingress/Egress Queue per Page values. > Firmware reads all of these things and makes all the > subsequent changes necessary. The Host Driver uses the SGE > Host Page Size in order to properly calculate BAR2 Offsets. > > Signed-off-by: Casey Leedom <leedom@chelsio.com> > Signed-off-by: Arjun Vynipadath <arjun@chelsio.com> > Signed-off-by: Ganesh Goudar <ganeshgr@chelsio.com> Applied.
