Subject: [PATCH v2 0/7] Cavium ThunderX2 SMMUv3 errata workarounds
Date: Thu, 4 May 2017 18:05:32 +0530 [thread overview]
Message-ID: <1493901339-14929-1-git-send-email-gakula@caviumnetworks.com> (raw)
From: Linu Cherian <linu.cherian@cavium.com>
Cavium ThunderX2 SMMUv3 implementation has two Silicon Erratas.
1. Errata ID #74
SMMU register alias Page 1 is not implemented
2. Errata ID #126
SMMU doesnt support unique IRQ lines and also MSI for gerror,
eventq and cmdq-sync
The following patchset does software workaround for these two erratas.
This series is based on patchset.
https://www.spinics.net/lists/arm-kernel/msg578443.html
Changes from v1:
Since the use of MIDR register is rejected and SMMU_IIDR is broken on this
silicon, as suggested by Will Deacon modified the patches to use ThunderX2
SMMUv3 IORT model number to enable errata workaround.
Geetha Sowjanya (1):
iommu/arm-smmu-v3: Add workaround for Cavium ThunderX2 erratum #126
Linu Cherian (6):
iommu/arm-smmu-v3: Introduce smmu option PAGE0_REGS_ONLY for ThunderX2
errata#74.
iommu/arm-smmu-v3: Do resource size checks based on SMMU option
PAGE0_REGS_ONLY
ACPICA: IORT: Add Cavium ThunderX2 SMMUv3 model definition.
iommu/arm-smmu-v3: For ACPI based device probing, set PAGE0_REGS_ONLY
option for ThunderX2 SMMUv3 implementations.
ACPI/IORT: Fixup SMMUv3 resource size for Cavium ThunderX2 SMMUv3
