[PATCH RESEND v2 0/2] Introduce SPAPR_NR_IPIS and fix max-cpus

Posted by Harsh Prateek Bora 1 year ago

On spapr, the max number of CPU IPIs are 4096 which is accounted during
spapr_irq_init but currently existing macro SPAPR_XIRQ_BASE is being
used to refer to that. Introducing SPAPR_NR_IPIS to refer to the range
of CPU IPIS which is being further used to initialize mc->max_cpus during
spapr_machine_class_init().

Harsh Prateek Bora (2):
  ppc/spapr: Introduce SPAPR_NR_IPIS to refer IRQ range for CPU IPIs.
  ppc/spapr: Initialize max_cpus limit to SPAPR_NR_IPIS.
