The benefit of these instructions is # performance (trading slower SRR0/1 with faster LR/CTR registers, and # entering the kernel with MSR[EE] and MSR[RI] left enabled, which can # reduce MSR updates. The scv instruction has 128 levels (not enough to # cover the Linux system call space). # # Assignment and advertisement # ---------------------------- # The proposal is to assign scv levels conservatively, and advertise # them with HWCAP feature bits as we add support for more. # # Linux has not enabled FSCR[SCV] yet, so executing the scv instruction # will cause the kernel to log a "SCV facility unavilable" message, and # deliver a SIGILL with ILL_ILLOPC to the process. Linux has defined a # HWCAP2 bit PPC_FEATURE2_SCV for SCV support, but does not set it. # # This change allocates the zero level ('scv 0'), advertised with # PPC_FEATURE2_SCV, which will be used to provide normal Linux system # calls (equivalent to 'sc'). # # Attempting to execute scv with other levels will cause a SIGILL to be # delivered the same as before, but will not log a "SCV facility # unavailable" message (because the processor facility is enabled). # # Calling convention # ------------------ # The proposal is for scv 0 to provide the standard Linux system call # ABI with the following differences from sc convention[1]: # # - LR is to be volatile across scv calls. This is necessary because the # scv instruction clobbers LR. From previous discussion, this should # be possible to deal with in GCC clobbers and CFI. # # - cr1 and cr5-cr7 are volatile. This matches the C ABI and would allow # the kernel system call exit to avoid restoring the volatile cr # registers (although we probably still would anyway to avoid # information leaks). # # - Error handling: The consensus among kernel, glibc, and musl is to # move to using negative return values in r3 rather than CR0[SO]=1 to # indicate error, which matches most other architectures, and is # closer to a function call. # # Notes # ----- # - r0,r4-r8 are documented as volatile in the ABI, but the kernel patch # as submitted currently preserves them. This is to leave room for # deciding which way to go with these. Some small benefit was found by # preserving them[1] but I'm not convinced it's worth deviating from # the C function call ABI just for this. Release code should follow # the ABI. # # Previous discussions: # https://lists.ozlabs.org/pipermail/linuxppc-dev/2020-April/208691.html #
