The outbound iATU programming functions are similar, so PATCH1 consolidates them into one. Most transactions' type are cfg0 and MEM, so current iATU usage is not balanced. PATCH2 adopts idea from Minghuan Lian <Minghuan.Lian@xxxxxxxxxxxxx>: http://www.spinics.net/lists/linux-pci/msg40440.html to change the iATU allocation: iATU0 for cfg and IO, iATU1 for MEM. Changes since v1: - remove outbound iATU programming for IO in dw_pcie_host_init, since it can be done by berlin_pcie_{rd|wr}_other_conf() latter. - only do outbound iATU programming for MEM if pp->ops->rd_other_conf is not set. Thank Fabrice Gasnier to point out "some platforms doesn't have support for ATU" Jisheng Zhang (2): PCI: designware: consolidate outbound iATU programming functions PCI: designware: use iATU0 for cfg and IO, iATU1 for MEM drivers/pci/host/pcie-designware.c | 142 ++++++++++++++++--------------------- 1 file changed, 60 insertions(+), 82 deletions(-) -- 2.1.4 -- 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
