ntb: intel: fix return value for ndev_vec_mask()

2019-11-28T17:28:52Z

[ Upstream commit 7756e2b5d68c36e170a111dceea22f7365f83256 ] ndev_vec_mask() should be returning u64 mask value instead of int. Otherwise the mask value returned can be incorrect for larger vectors.

ntb: ntb_hw_intel: init peer_addr in struct intel_ntb_dev

2016-11-13T21:48:29Z

The peer_addr member of intel_ntb_dev is not set, therefore when acquiring ntb_peer_db and ntb_peer_spad we only get the offset rather than the actual physical address. Adding fix to correct that. Signed-off-by: Dave Jiang Acked-by: Allen Hubbe Signed-off-by: Jon Mason

NTB: ntb_hw_intel: show BAR size in debugfs info

2016-08-05T14:33:47Z

It will be useful to know the hardware configured BAR size to diagnose issues with NTB memory windows. Signed-off-by: Allen Hubbe Acked-by: Dave Jiang Signed-off-by: Jon Mason

NTB: Fix macro parameter conflict with field name

2016-01-22T00:53:10Z

If the parameter given to the macro is replaced throughout the macro as it is evaluated. The intent is that the macro parameter should replace the only the first parameter to container_of(). However, the way the macro was written, it would also inadvertantly replace a structure field name. If a parameter of any other name is given to the macro, it will fail to compile, if the structure does not contain a field of the same name. At worst, it will compile, and hide improper access of an unintended field in the structure. Change the macro parameter name, so it does not conflict with the structure field name.

NTB: Clear property bits in BAR value

2016-01-11T14:51:17Z

The lower bits read from a BAR register will contain property bits that we do not care about. Clear those so that we can use the BAR values for limit and xlat registers. Reported-by: Conrad Meyer Signed-off-by: Dave Jiang Signed-off-by: Jon Mason

NTB: unify translation addresses

2015-11-08T21:11:21Z

There is no need for the upstream and downstream addresses to be different for the NTB configs. Go to using a single set of address. It is still possible to configure them differently using module parameter override however. Signed-off-by: Dave Jiang Acked and Tested-by: Allen Hubbe Signed-off-by: Jon Mason

NTB: Improve index handling in B2B MW workaround

2015-09-07T19:27:12Z

Check that b2b_mw_idx is in range of the number of memory windows when initializing the device. The workaround is considered to be in effect only if the device b2b_idx is exactly UINT_MAX, instead of any index past the last memory window. Only print B2B MW workaround information in debugfs if the workaround is in effect. Signed-off-by: Allen Hubbe Signed-off-by: Jon Mason
