The situation is not so bleak as this. See section B2.9 "Mismatched memory attributes" in the ARMv8 ARM ARM (DDI0487A.d), which lays out in some detail what the results of mismatched attributes are (generally, you lose ordering or coherency guarantees you might have hoped to have). They're not pretty, but it's not as bad as completely UNPREDICTABLE behaviour. thanks -- PMM _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
