into staging ppc patch queue 2016-10-28 This pull request supersedes and extends the one from 2016-10-26 (which had a build bug). Highlights: * SLOF (pseries guest firmware) update * Enable a number of extra testcases on ppc / pseries * Added the 'powernv' machine type - Almost enough to be minimally usable - But still missing necessary interrupt controller updates * Cleanup and consolidation of NVRAM handling on several platforms with related firmware * Substantial cleanup to device tree construction * Some more POWER9 instruction emulation * Cleanup to handling of pseries option vectors and CAS reboot handling (host/guest feature negotiation mechanism) * Significant cleanups to handling of PCI devices in test cases * New hotplug event infrastructure * Memory hot unplug support for pseries * Several bug fixes The NVRAM cleanup affects some Sun sparc platforms as well as ppc ones, but have been tested by the sparc maintainer (Mark Cave-Ayland). The test additions also include substantial general changes to the test framework that aren't strictly ppc related. They don't seem to break tests on other platforms, they're for the benefit of enabling tests on ppc and there isn't a specific maintainer for them, so they're included in this tree. # gpg: Signature made Fri 28 Oct 2016 02:37:19 BST # 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-2.8-20161028: (73 commits) ppc: allow certain HV interrupts to be delivered to guests spapr: Memory hot-unplug support spapr: use count+index for memory hotplug spapr: Add DRC count indexed hotplug identifier type spapr: add hotplug interrupt machine options spapr_events: add support for dedicated hotplug event source spapr: update spapr hotplug documentation target-ppc: Add xvcmpnesp, xvcmpnedp instructions target-ppc: add xscmp[eq,gt,ge,ne]dp instructions tests: Add pseries machine to the prom-env-test, too spapr_nvram: Pre-initialize the NVRAM to support the -prom-env parameter libqos: Change PCI accessors to take opaque BAR handle tests: Don't assume structure of PCI IO base in ahci-test tests: Use qpci_mem{read,write} in ivshmem-test libqos: Add 64-bit PCI IO accessors tests: Clean up IO handling in ide-test libqos: Implement mmio accessors in terms of mem{read,write} libqos: Add streaming accessors for PCI MMIO tests: Adjust tco-test to use qpci_legacy_iomap() libqos: Better handling of PCI legacy IO ...

2016-10-28ppc: allow certain HV interrupts to be delivered to guestsNicholas Piggin
ppc hypervisors have delivered system reset and machine check exception interrupts to guests in some situations (e.g., see FWNMI feature of LoPAPR, or NMI injection in QEMU). These exceptions are architected to set the HV bit in hardware, however when injected into a guest, the HV bit should be cleared. Current code masks off the HV bit before setting the new MSR, however this happens after the interrupt delivery model has calculated delivery mode for the exception. This can result in the guest's MSR LE bit being lost. Account for this in the exception handler and don't set HV bit for guest delivery. Also add another sanity check to ensure similar bugs get caught. Signed-off-by: Nicholas Piggin <npiggin@gmail.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

2016-10-28spapr: use count+index for memory hotplugMichael Roth
Commit 0a417869: spapr: Move memory hotplug to RTAS_LOG_V6_HP_ID_DRC_COUNT type dropped per-DRC/per-LMB hotplugs event in favor of a bulk add via a single LMB count value. This was to avoid overrunning the guest EPOW event queue with hotplug events. This works fine, but relies on the guest exhaustively scanning for pluggable LMBs to satisfy the requested count by issuing rtas-get-sensor(DR_ENTITY_SENSE, ...) calls until all the LMBs associated with the DIMM are identified. With newer support for dedicated hotplug event source, this queue exhaustion is no longer as much of an issue due to implementation details on the guest side, but we still try to avoid excessive hotplug events by now supporting both a count and a starting index to avoid unecessary work. This patch makes use of that approach when the capability is available.

2016-10-28spapr: add hotplug interrupt machine optionsMichael Roth
This adds machine options of the form: -machine pseries,modern-hotplug-events=true -machine pseries,modern-hotplug-events=false If false, QEMU will force the use of "legacy" style hotplug events, which are surfaced through EPOW events instead of a dedicated hot plug event source, and lack certain features necessary, mainly, for memory unplug support. If true, QEMU will enable support for "modern" dedicated hot plug event source. Note that we will still default to "legacy" style unless the guest advertises support for the "modern" hotplug events via ibm,client-architecture-support hcall during early boot. For pseries-2.7 and earlier we default to false, for newer machine types we default to true.

2016-10-28spapr_events: add support for dedicated hotplug event sourceMichael Roth
Hotplug events were previously delivered using an EPOW interrupt and were queued by linux guests into a circular buffer. For traditional EPOW events like shutdown/resets, this isn't an issue, but for hotplug events there are cases where this buffer can be exhausted, resulting in the loss of hotplug events, resets, etc. Newer-style hotplug event are delivered using a dedicated event source. We enable this in supported guests by adding standard an additional event source in the guest device-tree via /event-sources, and, if the guest advertises support for the newer-style hotplug events, using the corresponding interrupt to signal the available of hotplug/unplug events.
