From 5c3e66b17aeb04ab07029a468a14ef785178a3cb Mon Sep 17 00:00:00 2001 From: Minecrell Date: Fri, 29 Nov 2019 19:33:22 +0100 Subject: [PATCH 28/78] MSM8916: iommu/qcom: Select IOMMU_DMA instead of ARM_DMA_USE_IOMMU The ARM32 IOMMU DMA implementation does not really work properly with qcom_iommu. It fails to attach to any IOMMU because a domain is created by default in the driver. Now that there is IOMMU_DMA support for ARM32, select it instead of ARM_DMA_USE_IOMMU. --- drivers/iommu/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/iommu/Kconfig b/drivers/iommu/Kconfig index 04878caf6..6dab0ed7d 100644 --- a/drivers/iommu/Kconfig +++ b/drivers/iommu/Kconfig @@ -376,8 +376,8 @@ config QCOM_IOMMU bool "Qualcomm IOMMU Support" depends on ARCH_QCOM || (COMPILE_TEST && !GENERIC_ATOMIC64) select IOMMU_API + select IOMMU_DMA select IOMMU_IO_PGTABLE_LPAE - select ARM_DMA_USE_IOMMU help Support for IOMMU on certain Qualcomm SoCs. -- 2.31.1
