Hi Yu,

Linaro is currently working on adapting Android to run on ARM64. At this time this is currently a Linaro project only for our club and core members. We expect the work being done to be submitted upstream later in the year after our club and core members have had initial access to the work and provided feedback. Should you require further information, I suggest you contact Joe Bates.

Sincerely,

Scott

Hi,

I am from Marvell Semi Ltd, we are evaluating SW solutions to adapt Android to ARM64 SoC quickly. As I consulted with ARM support, they are recommending use 64/32, which run Android in AArch32 mode while kernel runs in AArch64 mode; and they referred me to Linaro as Linaro is working on it.

From http://www.linaro.org/engineering/armv8, we can build ARM64 kernel, and boot the kernel and rootfs from Foundation model; but no info on the Android side yet. So here we have a few questions about the Android side.

1. What's Linaro plans for adapt Android ARM64? Is there any high level plan or details to share?
2. From ARM64's annoucement, AArch32 is broadly compatible with ARMv7A. Are there high level issues identified for AArch32 android adaption so far?

3. Also, does Linaro have any plans for Android in AArch64 mode?

Please kindly let me know if there are other channels I shall pursue also. Any ideas will be appreciated.

Thanks,
Yu Tang
