ppc patch queue for 2017-03-01 I was hoping to get this pull request squeezed in before the soft freeze, but I ran into some difficulties during testing. Everything here was at least posted before the soft freeze, so I'm hoping we can still merge it for 2.9. The biggest things here are: * Cleanups to handling of hashed page tables, that will make adding support for the POWER9 MMU easier * Cleanups to the XICS interrupt controller that will make implementing the powernv machine easier * TCG implementation of extended overflow and carry handling for POWER9 It also includes: * Increasing the CPU limit for pseries to 1024 vCPUs * Generating proper OF node names in qemu (making hotplug and coldplug logic closer together) # gpg: Signature made Wed 01 Mar 2017 04:43:06 GMT # gpg: using RSA key 0x6C38CACA20D9B392 # gpg: Good signature from "David Gibson <david@gibson.dropbear.id.au>" # gpg: aka "David Gibson (Red Hat) <dgibson@redhat.com>" # gpg: aka "David Gibson (ozlabs.org) <dgibson@ozlabs.org>" # gpg: aka "David Gibson (kernel.org) <dwg@kernel.org>" # Primary key fingerprint: 75F4 6586 AE61 A66C C44E 87DC 6C38 CACA 20D9 B392 * remotes/dgibson/tags/ppc-for-2.9-20170301: (50 commits) Add PowerPC 32-bit guest memory dump support ppc/xics: rename 'ICPState *' variables to 'icp' ppc/xics: move InterruptStatsProvider to the sPAPR machine ppc/xics: move ics-simple post_load under the machine ppc/xics: remove the XICSState classes ppc/xics: export the XICS init routines ppc/xics: move the ICP array under the sPAPR machine ppc/xics: register the reset handler of ICP objects ppc/xics: simplify spapr_dt_xics() interface ppc/xics: use the QOM interface to grab an ICP ppc/xics: move the cpu_setup() handler under the ICPState class ppc/xics: simplify the cpu_setup() handler ppc/xics: move kernel_xics_fd out of KVMXICSState ppc/xics: extend the QOM interface to handle ICPs ppc/xics: remove the XICS list of ICS ppc/xics: register the reset handler of ICS objects ppc/xics: remove xics_find_source() ppc/xics: use the QOM interface to resend irqs ppc/xics: use the QOM interface to get irqs ppc/xics: use the QOM interface under the sPAPR machine ...

This patch extends support for the `dump-guest-memory` command to the 32-bit PowerPC architecture. It relies on the assumption that a 64-bit guest will not dump a 32-bit core file (and vice versa). [dwg: I suspect this patch won't cover all cases, in particular a 32-bit machine type on a 64-bit qemu build. However, it does strictly more than what we had before, so might as well apply as a starting point] Signed-off-by: NMike Nawrocki <michael.nawrocki@gtri.gatech.edu> Signed-off-by: NDavid Gibson <david@gibson.dropbear.id.au>

The ICS object uses a post_load() handler which is implicitly relying on the fact that the internal state of the ICS and ICP objects has been restored but this is not guaranteed. So, let's move the code under the post_load() handler of the machine where we know the objects have been fully restored. The icp_resend() handler of the XICSFabric QOM interface is also removed as it is now obsolete.

Today, the ICS (Interrupt Controller Source) object is created and realized by the init and realize routines of the XICS object, but some of the parameters are only known at the machine level. These parameters are passed from the sPAPR machine to the ICS object in a rather convoluted way using property handlers and a class handler of the XICS object. The number of irqs required to allocate the IRQ state objects in the ICS realize routine is one of them. Let's simplify the process by creating the ICS object along with the XICS object at the machine level and link the ICS into the XICS list of ICSs at this level also. In the sPAPR machine, there is only a single ICS but that will change with the PowerNV machine. Also, QOMify the creation of the objects and get rid of the superfluous code.

Currently xics - the component of the IBM POWER interrupt controller representing the overall interrupt fabric / architecture is represented as a descendent of SysBusDevice. However, this is not really correct - the xics presents nothing in MMIO space so it should be an "unattached" device in the current QOM model. Since this device will always be created by the machine type, not created specifically from the command line, and because it has no migrated state it should be safe to move it around the device composition tree. Therefore this patch changes it to a descendent of TYPE_DEVICE, and makes it an unattached device. So that its reset handler still gets called correctly, we add a qdev_set_parent_bus() to attach it to sysbus. It's not really clear that's correct (instead of using register_reset()) but it appears to a common technique.

But it has no real justification either, other than being the consequence of the way fdt_add_subnode() inserts new elements to the front of the FDT rather than adding them to the tail. This patch reverts to the historical SLOF ordering by walking PCI devices in reverse order. This reconciles pseries with x86 machine types behavior. It is expected to make things easier when porting existing applications to power.
