I agree with the 'potentially fragile' assessment, however experimentation by Guodong and me showed that the CCI must be enabled on all cores and done before the bootwrapper drops into non-secure mode. I.e. before we get the chance to enter the C code and easily parse device-tree. Perhaps there is something we need to do to get access to CCI in non secure mode? -- Tixy _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/cucslists/listinfo/kvmarm
