This series goes on top of the unmerged machine check handler
changes
https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=118814
This carries on with the goal of unwinding macros and consolidating
code. This gets most of the way there, but we have traded that
improvement for another problem, which is the argument list for code
generation macros is unwieldy.
INT_HANDLER system_reset, 0x100, 0, 0, 0, EXC_STD, PACA_EXNMI, 0, 0, 0, 0, 1
There are two possible ways I see to solve this. One is to come up
with new sets of constants for each argument.
INT_HANDLER system_reset, 0x100, INLINE, FULL, REAL, EXC_STD, PACA_EXNMI,
CLEAR_RI, NO_DAR, NO_DSISR, NO_MASK, KVM
I don't really like that, my preferred way is we can set symbols to
configure the behaviour of the code generation macro.
INT_DEFINE_BEGIN(system_reset)
IVEC=0x100
IHSRR=0
IAREA=PACA_EXNMI
ISET_RI=0
IKVM_REAL=1
INT_DEFINE_END(data_access)
INT_HANDLER system_reset
Any other suggestions?
Thanks,
Nick
