Subject: [PATCH v8 6/7] iommu/arm-smmu-qcom: Use the custom fault handler on more platforms
Date: Wed, 17 Apr 2024 06:37:30 -0700 [thread overview]
Message-ID: <20240417133731.2055383-7-quic_c_gdjako@quicinc.com> (raw)
In-Reply-To: <20240417133731.2055383-1-quic_c_gdjako@quicinc.com>
The TBU support is now available, so let's allow it to be used on other
platforms that have the Qualcomm SMMU-500 implementation with TBUs. This
will allow the context fault handler to query the TBUs when a context
fault occurs.
