• Questions about Generic Timer in ARMv8

    When two clusters(Big/Little) exist in SoC, the timer can be used to support Synchronization between two clusters.

    But How to understand "Synchronization", anybody can tell me some typical application context? I am really confused......

    And, if…

  • Different performance in HYP and SVC mode ARMv7A?

    I'm doing some testing on Exynos5422 SoC which implements big.LITTLE architecture (A7 + A15), I'm running bare metal application which starts in HYP mode. I haven't returned from HYP mode by accident and then software delay which I implemented by simple…
