ntb: ntb_hw_intel: link_poll isn't clearing the pending status properly

2017-02-17T04:11:26+00:00

On Skylake hardware, the link_poll isn't clearing the pending interrupt
bit.  Adding a new function for SKX that handles clearing of status bit the
right way.

ntb: Adding Skylake Xeon NTB support

2016-12-23T21:09:10+00:00

The Skylake Xeon NTB hardware has made some changes to the register name,
offset, and the way doorbells work. Adding driver support for the new
hardware.

ntb: ntb_hw_intel: init peer_addr in struct intel_ntb_dev

2016-11-13T21:48:29+00:00

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.

NTB: Fix macro parameter conflict with field name

2016-01-22T00:53:10+00:00

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

2016-01-11T14:51:17+00:00

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.
