Subject: [PATCH 0/4] ppc/xive: Rework Inter chip communication
Date: Tue, 29 Aug 2023 16:32:32 +0200	[thread overview]
Message-ID: <20230829143236.219348-1-clg@kaod.org> (raw)

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.

  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
