From ba293fff085fde5b9f1b5a57c8abb1a8098d0c59 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Fri, 23 Sep 2005 14:43:22 +1000 Subject: ppc46 iSeries: Make some generic irq code compile for iSeries In order to call finish_device_tree() on iSeries we need to define virt_irq_create_mapping(). We also need to set ppc64_interrupt_controller to something other than zero. If we want to do interrupt setup via the device tree on iSeries this code will need some serious work, but it's harmless to have it there as long as the nodes in the iSeries device tree don't cause it to be invoked.

On iSeries the Hypervisor has already inserted some ptes for us, and we simply have to detect that and bolt them. iSeries_hpte_bolt_or_insert() implements that logic. For the case of a non-existing pte we just call iSeries_hpte_insert(). This appears to work, although it's not entirely equivalent to the old code in iSeries_make_pte() which panicked if we got a secondary slot. Not sure if that's important. Finally we call iSeries_hpte_bolt_or_insert() from create_pte_mapping(), which is called from htab_initialize() for each lmb region.
