Hi all,
The following set of patches will provide support for a 32-bit Android file system running on top of 64-bit kernel. We have tested them successfully on 64-bit platforms (Real Time Simulation Model ARMv8) as well as on 32-bit ones (4xA9 Versatile Express). For RTSMv8 we have been using 64-bit kernel build, running the CPU in the AArch64 state, and an ARMv7 file system build, running in AArch32 state of ARMv8.
Please take a look and let me know if you have any feedback.
Note: This set of patches will affect only an Android build of the Linux kernel, the drivers(binder, ashmem) are not pulled in for a default Linux build.
Best Regards, Serban Constantinescu PDSW Engineer ARM Ltd.
