Subject: [PATCH v20 01/19] PCI: Add INTx Mechanism Messages macros
Date: Fri, 25 Aug 2023 18:32:01 +0900 [thread overview]
Message-ID: <20230825093219.2685912-2-yoshihiro.shimoda.uh@renesas.com> (raw)
In-Reply-To: <20230825093219.2685912-1-yoshihiro.shimoda.uh@renesas.com>
Add "Message Routing" and "INTx Mechanism Messages" macros to enable
a PCIe driver to send messages for INTx Interrupt Signaling.
The "Message Routing" is from Table 2-17, and the "INTx Mechanism
Messages" is from Table 2-18 on the PCI Express Base Specification,
Rev. 4.0 Version 1.0.
