WebAm I correct when I say that this means that any secure OS can disable group 0 interrupt, which could prevent the secure monitor at EL3 to receive group 0 interrupt ? Is the only way to prevent this is to trap access to ICC_SRE_EL1 using ICC_SRE_EL3.Enable ? Whether S.EL1 can access ICC_IGRPEN0_EL1 depends on the setting of SCR_EL3.FIQ. metal roofing contractors in buffalo ny area
