• Does E0PD mechanism provide Meltdown mitigation?
    ARMv8.5 introduces E0PD mechanism that changes faults timing (as declared in spec). Other side, there is a patch to Linux kernel that disables KPTI if cores support E0PD. From description in spec it's...

  • If the mispredict happen, is there a mechanism to abort the instructions(have been fetched or decoded)?
    If the mispredict happen, is there a mechanism to abort the instructions(have been fetched or decoded)? If there is the mechanism, how does it work? Thanks very much!

  • Does Cortex-M0+ has a flash patch mechanism similar to the FPB function of Cortex-M4?
    Hello, As shown in title, does cortex-m0+ has flash patch and break point(FPB) function similar to cortex-m4, which will facilitate the upgrading of ROM code in the form of hardware. Thanks
