Subject: [PATCH AUTOSEL 5.14 19/32] PCI: Add ACS quirks for Cavium multi-function devices
Date: Sat, 11 Sep 2021 09:11:36 -0400 [thread overview]
Message-ID: <20210911131149.284397-19-sashal@kernel.org> (raw)
In-Reply-To: <20210911131149.284397-1-sashal@kernel.org>
From: George Cherian <george.cherian@marvell.com>
[ Upstream commit 32837d8a8f63eb95dcb9cd005524a27f06478832 ]
Some Cavium endpoints are implemented as multi-function devices without ACS
capability, but they actually don't support peer-to-peer transactions.
Add ACS quirks to declare DMA isolation for the following devices:
- BGX device found on Octeon-TX (8xxx)
- CGX device found on Octeon-TX2 (9xxx)
- RPM device found on Octeon-TX3 (10xxx)
