[PATCH 0/4] ppc/xive: Rework Inter chip communication

[Cédric Le Goater]

Hello,

Today, the inter chip communication for interrupts uses the
pnv_xive_get_remote() routine to grab the remote XIVE interrupt
controller object. This is a modeling shortcut which can be improved
by implementing :

 * remote END triggers
 * memory operations on remote NVT structures.

Both are addressed by this series for P9. P10 should be similar.

Thanks,

C. 

Cédric Le Goater (4):
  ppc/xive: Use address_space routines to access the machine RAM
  ppc/xive: Introduce a new XiveRouter end_notify() handler
  ppc/xive: Handle END triggers between chips with MMIOs
  ppc/xive: Add support for the PC MMIOs
