Subject: [PATCH v3] PCI: Add ACS quirk for NXP LX2XX0 and LX2XX2 platforms
Date: Tue, 3 Aug 2021 20:00:21 +0200 [thread overview]
Message-ID: <20210803180021.3252886-1-wasim.khan@oss.nxp.com> (raw)
From: Wasim Khan <wasim.khan@nxp.com>
Root Ports in NXP LX2XX0 and LX2XX2 where each Root Port
is a Root Complex with unique segment numbers do provide
isolation features to disable peer transactions and
validate bus numbers in requests, but do not provide an
actual PCIe ACS capability.
Add ACS quirk for NXP LX2XX0 A/C/E/N and LX2XX2 A/C/E/N
platforms
LX2XX0A : without security features + CAN-FD
LX2160A (0x8d81) - 16 cores
LX2120A (0x8da1) - 12 cores
LX2080A (0x8d83) - 8 cores
LX2XX0C : security features + CAN-FD
LX2160C (0x8d80) - 16 cores
LX2120C (0x8da0) - 12 cores
LX2080C (0x8d82) - 8 cores
LX2XX0E : security features + CAN
LX2160E (0x8d90) - 16 cores
LX2120E (0x8db0) - 12 cores
LX2080E (0x8d92) - 8 cores
LX2XX0N : without security features + CAN
LX2160N (0x8d91) - 16 cores
LX2120N (0x8db1) - 12 cores
LX2080N (0x8d93) - 8 cores
LX2XX2A : without security features + CAN-FD
LX2162A (0x8d89) - 16 cores
LX2122A (0x8da9) - 12 cores
LX2082A (0x8d8b) - 8 cores
LX2XX2C : security features + CAN-FD
LX2162C (0x8d88) - 16 cores
LX2122C (0x8da8) - 12 cores
LX2082C (0x8d8a) - 8 cores
LX2XX2E : security features + CAN
LX2162E (0x8d98) - 16 cores
LX2122E (0x8db8) - 12 cores
LX2082E (0x8d9a) - 8 cores
LX2XX2N : without security features + CAN
LX2162N (0x8d99) - 16 cores
LX2122N (0x8db9) - 12 cores
LX2082N (0x8d9b) - 8 cores
