Subject: [PATCH v2 0/4] Prepare for ECMDQ support
Date: Mon, 16 Aug 2021 15:29:00 +0800 [thread overview]
Message-ID: <20210816072904.1897-1-thunder.leizhen@huawei.com> (raw)
v1 --> v2:
1. Stop pre-zeroing batch commands. Patch 1 is modified. Other patches remain unchanged.
Before:
struct arm_smmu_cmdq_batch cmds = {};
After:
struct arm_smmu_cmdq_batch cmds;
cmds.num = 0;
RFC --> v1
1. Resend the patches for ECMDQ preparation and remove the patches for ECMDQ implementation.
2. Patch 2 is modified. Other patches remain unchanged.
1) Add static helper __arm_smmu_cmdq_issue_cmd(), and make arm_smmu_cmdq_issue_cmd()
and arm_smmu_cmdq_issue_cmd_with_sync() implement based on it.
2) Remove unused arm_smmu_cmdq_issue_sync().
