Hi, Everyone, This patch series adds support of >=4G memory windows. Current Switchtec's BAR setup registers are limited to 32bits, corresponding to the maximum MW (memory window) size is <4G. Increase the MW sizes with the addition of the BAR Setup Extension Register for the upper 32bits of a 64bits MW size. This increases the MW range to between 4K and 2^63. Additionally, we've made the following changes: * debug print 64bit aligned crosslink BAR numbers * Fix the array size of NT req id mapping table Tested with ntb_test.sh successfully based on NTB fixes series from Logan Gunthorpe <logang@xxxxxxxxxxxx> at https://github.com/sbates130272/linux-p2pmem on branch of ntb_multiport_fixes Regards, Wesley -- Changed since v1: - Using upper_32_bits() and lower_32_bits() marcos makes it easier to read and avoids compiler warning on 32-bit arch - Reorder the patches to make the bug fixes first and add a "Fixes" line to the commit messages -- Paul Selles (2): ntb_hw_switchtec: debug print 64bit aligned crosslink BAR Numbers ntb_hw_switchtec: Added support of >=4G memory windows Wesley Sheng (1): ntb_hw_switchtec: NT req id mapping table register entry number should be 512 drivers/ntb/hw/mscc/ntb_hw_switchtec.c | 11 ++++++++--- include/linux/switchtec.h | 10 +++++++--- 2 files changed, 15 insertions(+), 6 deletions(-) -- 2.7.4
