-Qemu 3.1 Aarch64 TLBI VAE1, x0
-
-Hello,
-
-In my code I'm trying to remove some permissions to a 4KiB MMU descriptor. After that I invalidate the MMU with 
-
-TLBI VAE1, x0
-
-where x0 is the start of the address of the 4 KiB page. 
-
-In Qemu 2.12 this did not work, but I worked around it with:
-
-
-    /* invalidate the address */
-    TLBI VAE1, x0
-

-    /*****************************************************************/

-    /* NOTE: THIS IS A TRICK FOR QEMU!!!!!!!!!!!!                                                               */
-    /* Apparently we have to change the TTBR0_EL1 when we change a descriptor (especially to remove permissions) */
-    /* Otherwise qemu (2.12) will continue with the same descriptor with permissions!                          **/

-    mrs     x1 , TTBR0_EL1

-
-    isb
-
-    msr     TTBR0_EL1 , x1
-
-    /* return from function */
-    ret
-
-
-That is, I just replaced the TTBR0_EL1 with a temporary value, and then restored it. (guess qemu 2.12 just needed to reload the values again).
-
-However, even this procedure is not working with qemu 3.1. (I just tested again with qemu 2.12 and the code works fine, with qemu 3.1 it does not).
-
-Thanks,
-Pharos team
-
-Could you provide a test binary (and the QEMU command line to run it) that demonstrates the bug, please?
-
-
-Marking bug as incomplete -- we can't investigate without a test case.
