I just had a better idea - it is compact but regular and one can see at
a quick glance which block is for which set of MSRs:
u32 mca_msr_reg(int bank, enum mca_msr reg)
{
if (mce_flags.smca) {
switch (reg) {
case MCA_CTL: return MSR_AMD64_SMCA_MCx_CTL(bank); break;
case MCA_ADDR: return MSR_AMD64_SMCA_MCx_ADDR(bank); break;
case MCA_MISC: return MSR_AMD64_SMCA_MCx_MISC(bank); break;
case MCA_STATUS: return MSR_AMD64_SMCA_MCx_STATUS(bank); break;
default: goto out; break;
}
}
switch (reg) {
case MCA_CTL: return MSR_IA32_MCx_CTL(bank); break;
case MCA_ADDR: return MSR_IA32_MCx_ADDR(bank); break;
case MCA_MISC: return MSR_IA32_MCx_MISC(bank); break;
case MCA_STATUS: return MSR_IA32_MCx_STATUS(bank); break;
default: goto out; break;
}
out:
WARN_ON_ONCE(1);
return 0;
}
