Subject: [PATCH AUTOSEL 5.4 07/14] PCI: Add ACS quirks for Cavium multi-function devices
Date: Sat, 11 Sep 2021 09:13:38 -0400	[thread overview]
Message-ID: <20210911131345.285564-7-sashal@kernel.org> (raw)
In-Reply-To: <20210911131345.285564-1-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)
