Subject: [PATCH 00/19] Implement NTB Controller using multiple PCI EP
Date: Thu, 14 May 2020 20:29:08 +0530 [thread overview]
Message-ID: <20200514145927.17555-1-kishon@ti.com> (raw)
This series is about implementing SW defined NTB using
multiple endpoint instances. This series has been tested using
2 endpoint instances in J7 connected to two DRA7 boards. However there
is nothing platform specific for the NTB functionality.
This was presented in Linux Plumbers Conference. The presentation
can be found @ [1]
RFC patch series can be found @ [2]
This series has been validated after applying [3] and [4]
Changes from RFC:
1) Converted the DT binding patches to YAML schema and merged the
DT binding patches together
2) NTB documentation is converted to .rst
3) One HOST can now interrupt the other HOST using MSI-X interrupts
4) Added support for teardown of memory window and doorbell
configuration
5) Add support to provide support 64-bit memory window size from
DT
