2017-08-04phb4: Enable PCI peer-to-peerFrederic Barrat1-0/+50
P9 supports PCI peer-to-peer: a PCI device can write directly to the mmio space of another PCI device. It completely by-passes the CPU. It requires some configuration on the PHBs involved: 1. on the initiating side, the address for the read/write operation is in the mmio space of the target, i.e. well outside the range normally allowed. So we disable range-checking on the TVT entry in bypass mode. 2. on the target side, we need to explicitly enable p2p by setting a bit in a configuration register. It has the side-effect of reserving an outbound (as seen from the CPU) store queue for p2p. Therefore we only enable p2p on the PHBs using it, as we don't want to waste the resource if we don't have to. P9 supports p2p mmio writes. Reads are currently only supported if the two devices are under the same PHB but that is expected to change in the future, and it raises questions about intermediate switches configuration, so we report an error for the time being. The patch adds a new OPAL call to allow the OS to declare a p2p (initiator, target) pair.

2017-07-13numa/associativity: Add a new level of NUMA for GPU'sBalbir Singh1-1/+1
Today we have an issue where the NUMA nodes corresponding to GPU's have the same affinity/distance as normal memory nodes. Our reference-points today supports two levels [0x4, 0x4] for normal systems and [0x4, 0x3] for Power8E systems. This patch adds a new level [0x4, X, 0x2] and uses node-id as at all levels for the GPU.

2017-06-07doc: Fix output of version string when using Sphinx with Python 3Andrew Donnellan1-2/+2
Our Sphinx configuration gets the current skiboot version by using the subprocess module to run make_version.sh. In Python 2, this returns a value of type str, but in Python 3, this returns bytes instead. Decode those bytes into a string so we see "skiboot 5.6.blah" rather than "skiboot b'5.6.blah\n'" in the documentation output. Tested using Sphinx with both Python 2 and 3.

2017-05-31occ: Fix Pstate ordering for P9Shilpasri G Bhat2-10/+48
In P9 the pstate values are positive. They are continuous set of unsigned integers [0 to +N] where Pmax is 0 and Pmin is N. The linear ordering of pstates for P9 has changed compared to P8. P8 has neagtive pstate values advertised as [0 to -N] where Pmax is 0 and Pmin is -N. This patch adds helper routines to abstract pstate comparison with pmax and adds sanity pstate limit checks. This patch also fixes pstate arithmetic by using labs(). Suggested-by: Gautham R.

2017-03-30Introduce NPU2 supportAlistair Popple2-6/+43
NVLink2 is a new feature introduced on POWER9 systems. It is an evolution of of the NVLink1 feature included in POWER8+ systems but adds several new features including support for GPU address translation using the Nest MMU and cache coherence. Similar to NVLink1 the functionality is exposed to the OS as a series of virtual PCIe devices. However the actual hardware interfaces are significantly different which limits the amount of common code that can be shared between implementations in the firmware. This patch adds basic hardware initialisation and exposure of the virtual NVLink2 PCIe devices to the running OS.

2017-02-22core/pci: Mark broken PDC on slots without surprise hotplug capabilityGavin Shan1-10/+12
We has to support surprise hotplug on PCI slots that don't support it on hardware. So we're fully utilizing the PCIe link state change event to detect the events (hot-remove and hot-add). The PDC (Presence Detection Change) event isn't reliable for the purpose. For example, PEX8718 on superMicro's machines. This adds another PCI slot property "ibm,slot-broken-pdc" in the device-tree, to indicate the PDC isn't reliable on those (software claimed) surprise pluggable slots.
