>What I'd hoped is that rather than needing a hook for this, you could just override smmu_domain->tlb_ops from .init_context to wire up the alternate .sync method directly. That would save this extra level of indirection.
Hi Robin, overriding tlb_ops->tlb_sync function is not enough here.
There are direct references to arm_smmu_tlb_sync_context(), arm_smmu_tlb_sync_global() functions.
In arm-smmu.c. we can replace these direct references with tlb_ops->tlb_sync() function except in one function arm_smmu_device_reset().
When arm_smmu_device_reset() gets called, domains are not initialized and tlb_ops is not available.
Should we add a new hook for arm_smmu_tlb_sync_global() or make this as a responsibility of impl->reset() hook as it gets
called at the same place?
-KR
