Xiao Guangrong ran kvm-unit-tests on an actual machine with PKU and found that it fails: test pte.p pte.user pde.p pde.user pde.a pde.pse pkru.wd pkey=1 user write efer.nx cr4.pke: FAIL: error code 27 expected 7 Dump mapping: address: 0x123400000000 ------L4: 2ebe007 ------L3: 2ebf007 ------L2: 8000000020000a5 (All failures are combinations of "pde.user pde.p pkru.wd pkey=1", plus either "pde.pse" or "pte.p pte.user", plus one of "user cr0.wp", "cr0.wp" or "user", plus unimportant bits such as accessed/dirty or efer.nx). So PFEC.PKEY is set even if the ordinary check failed (which it did because pde.w is zero). Adjust QEMU to match behavior of silicon. Backports commit 44d066a2f770ee9d61fd1c2a609bdf2a994dfdf7 from qemu |
