However, as there was a previous iteration, it is suggested to include the changelog between RFC and v1. > > Bibek Kumar Patro (3): > iommu/arm-smmu: introduction of ACTLR for custom prefetcher settings > iommu/arm-smmu: add ACTLR data and support for sm8550 > iommu/arm-smmu: re-enable context caching in smmu reset operation > > drivers/iommu/arm/arm-smmu/arm-smmu-qcom.c | 143 ++++++++++++++++++++- > drivers/iommu/arm/arm-smmu/arm-smmu-qcom.h | 2 + Although it is not mentioned in the MAINTAINERS file, could you please CC linux-arm-msm when sending v2? > drivers/iommu/arm/arm-smmu/arm-smmu.c | 5 +- > drivers/iommu/arm/arm-smmu/arm-smmu.h | 5 + > 4 files changed, 146 insertions(+), 9 deletions(-) > > -- > 2.17.1 >

Although the RFC patch was a WIP patch in rough state, sent to take upstream inputs. Will try adding the changelog in v2. To give a context, in the RFC patch, we we're initially proposing a dt based approach to set the actlr property, where we would piggyback on the iommus property to store actlr value and set the property during smmu device probe. >> >> Bibek Kumar Patro (3): >> iommu/arm-smmu: introduction of ACTLR for custom prefetcher settings >> iommu/arm-smmu: add ACTLR data and support for sm8550 >> iommu/arm-smmu: re-enable context caching in smmu reset operation >> >> drivers/iommu/arm/arm-smmu/arm-smmu-qcom.c | 143 ++++++++++++++++++++- >> drivers/iommu/arm/arm-smmu/arm-smmu-qcom.h | 2 + > > Although it is not mentioned in the MAINTAINERS file, could you please > CC linux-arm-msm when sending v2? > Sure Dmitry, will take care of this and CC linux-arm-msm while sending v2. >> drivers/iommu/arm/arm-smmu/arm-smmu.c | 5 +- >> drivers/iommu/arm/arm-smmu/arm-smmu.h | 5 + >> 4 files changed, 146 insertions(+), 9 deletions(-) >> >> -- >> 2.17.1 >> > >
