- iommu/arm-smmu-qcom: Add SM6115 MDSS compatible
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
iommu/arm-smmu-qcom: Add SM6115 MDSS compatible
Add the SM6115 MDSS compatible to clients compatible list, as it also needs that workaround. Without this workaround, for example, QRB4210 RB2 which is based on SM4250/SM6115 generates a lot of smmu unhandled context faults during boot:
armsmmucontext_fault: 116854 callbacks suppressed arm-smmu c600000.iommu: Unhandled context fault: fsr=0x402, iova=0x5c0ec600, fsynr=0x320021, cbfrsynra=0x420, cb=5 arm-smmu c600000.iommu: FSR = 00000402 [Format=2 TF], SID=0x420 arm-smmu c600000.iommu: FSYNR0 = 00320021 [S1CBNDX=50 PNU PLVL=1] arm-smmu c600000.iommu: Unhandled context fault: fsr=0x402, iova=0x5c0d7800, fsynr=0x320021, cbfrsynra=0x420, cb=5 arm-smmu c600000.iommu: FSR = 00000402 [Format=2 TF], SID=0x420
and also failed initialisation of lontium lt9611uxc, gpu and dpu is observed: (binding MDSS components triggered by lt9611uxc have failed)
