SL_00_001 - bionic
About
bionic is Android's C library. A historical focus was on minimizing assembler, so very little new code actually needed writing. bionic reuses the Linux UAPI headers, so those definitions all came direct from the kernel.
Note: The RISCV64 ABI for Android mandates "V" extension, so discovery isn't necessary... only state save/restore (which is part of 6.5 already)
Dependencies
Need kernel hardware breakpoint support (https://github.com/google/android-riscv64/issues/75), tracked as LK_01_005 (see https://docs.google.com/spreadsheets/d/177dFIMBbhiLsFI9H_yjoAo_Hr9yu1tfINJfZQTcUC2Y/edit#gid=0).
Status
Development | ONGOING | Missing support for hardware breakpoints because kernel has no riscv64 ptrace() equivalent to arm64 |
