Subject: [PATCH V2 0/4] NTB function for PCIe RC to EP connection
Date: Tue, 22 Feb 2022 10:23:51 -0600 [thread overview]
Message-ID: <20220222162355.32369-1-Frank.Li@nxp.com> (raw)
This implement NTB function for PCIe EP to RC connections.
The existed ntb epf need two PCI EPs and two PCI Host.
This just need EP to RC connections.
