Webbsctlr_el3寄存器的EE位有两种值0和1，决定了EL3级别数据访问的大小端模式，也决定了EL3 在TLB进行虚实转换的stage1时的大小端格式。 WXN 位主要是用于控制可写内存区域是否是XN。 当该bit置1时，在EL3 TLB转换表里所有的 writable 的 memory region 都会被视为 XNExecute-never ，也就意味着相应的 memory region 将无法执行 instructions，应该就 … WebbEL0 accessibility to cache maintenance instructions. The SCTLR_EL1.UCI bit enables EL0 access for the DC CVAU, DC CVAC, DC CVAP, DC CIVAC, and IC IVAU instructions. When EL0 use of these instructions is disabled because SCTLR_EL1.UCI == 0, executing one of these instructions at EL0 generates a trap to EL1, that is reported using EC = 0x18.

Webb27 nov. 2024 · Hello Pekka, we've seen these "Unhandled Exception in EL3" now and then, too, and it was always a bug in some driver code that accessed a memory location it shouldn't have accessed, but I'm wondering if it is really intentional that these faults lead to a panic in the ATF (at least I think that's where the message comes from).
