Module cortex_a::registers::SCTLR_EL1::WXN [−][src]
Expand description
Write permission implies XN (Execute-never). For the EL1&0 translation regime, this bit can force all memory regions that are writable to be treated as XN.
0 This control has no effect on memory access permissions.
1 Any region that is writable in the EL1&0 translation regime is forced to XN for accesses from software executing at EL1 or EL0.
The WXN bit is permitted to be cached in a TLB.
When ARMv8.1-VHE is implemented, and the value of HCR_EL2.{E2H, TGE} is {1, 1}, this bit has no effect on the PE.
