Hmm? We have
{ .name = "ID_AA64DFR0_EL1", .state = ARM_CP_STATE_AA64,
.opc0 = 3, .opc1 = 0, .crn = 0, .crm = 5, .opc2 = 0,
.access = PL1_R, .type = ARM_CP_CONST,
/* We mask out the PMUVer field, because we don't currently
* implement the PMU. Not advertising it prevents the guest
* from trying to use it and getting UNDEFs on registers we
* don't implement.
*/
.resetvalue = cpu->id_aa64dfr0 & ~0xf00 },
which strongly suggests that we implement it... is that buggy somehow?
thanks
