Subject: [PATCH v13 02/10] iommu/arm-smmu-v3: Pass in cmdq pointer to arm_smmu_cmdq_build_sync_cmd
Date: Fri, 23 Aug 2024 17:10:36 -0700 [thread overview]
Message-ID: <50bd0237e8399496955c2db2c8fde5bb0c564343.1724453781.git.nicolinc@nvidia.com> (raw)
In-Reply-To: <cover.1724453781.git.nicolinc@nvidia.com>
The CMDQV extension on NVIDIA Tegra241 SoC only supports CS_NONE in the
CS field of CMD_SYNC, v.s. standard SMMU CMDQ. Pass in the cmdq pointer
directly, so the function can identify a different cmdq implementation.
