- =================================
- INTERNAL KERNEL ABI FOR FR-V ARCH
- =================================
-
-The internal FRV kernel ABI is not quite the same as the userspace ABI. A number of the registers
-are used for special purposed, and the ABI is not consistent between modules vs core, and MMU vs
-no-MMU.
-
-This partly stems from the fact that FRV CPUs do not have a separate supervisor stack pointer, and
-most of them do not have any scratch registers, thus requiring at least one general purpose
-register to be clobbered in such an event. Also, within the kernel core, it is possible to simply
-jump or call directly between functions using a relative offset. This cannot be extended to modules
-for the displacement is likely to be too far. Thus in modules the address of a function to call
-must be calculated in a register and then used, requiring two extra instructions.
