Enum cortex_a::registers::SCTLR_EL1::DZE::Value [−][src]
#[repr(u64)]
pub enum Value {
Trap,
DontTrap,
}
Expand description
Traps EL0 execution of DC ZVA instructions to EL1, from AArch64 state only.
0 Any attempt to execute a DC ZVA instruction at EL0 using AArch64 is trapped to EL1. Reading DCZID_EL0.DZP from EL0 returns 1, indicating that DC ZVA instructions are not supported.
1 This control does not cause any instructions to be trapped.
When ARMv8.1-VHE is implemented, and the value of HCR_EL2.{E2H, TGE} is {1, 1}, this bit has no effect on execution at EL0.
