2019-03-04powercap: occ: Fix the powercapping range allowed for userShilpasri G Bhat1-1/+8
[ Upstream commit a96739c6c1cdf02521cab703733cef8cb54debbf ] OCC provides two limits for minimum powercap. One being hard powercap minimum which is guaranteed by OCC and the other one is a soft powercap minimum which is lesser than hard-min and may or may not be asserted due to various power-thermal reasons. So to allow the users to access the entire powercap range, this patch exports soft powercap minimum as the "powercap-min" DT property. And it also adds a new DT property called "powercap-hard-min" to export the hard-min powercap limit.

2018-07-03npu2: Use same compatible string for NVLink and OpenCAPI link nodes in ↵Andrew Donnellan1-4/+6
device tree Currently, we distinguish between NPU links for NVLink devices and OpenCAPI devices through the use of two different compatible strings - ibm,npu-link and ibm,npu-link-opencapi. As we move towards supporting configurations with both NVLink and OpenCAPI devices behind a single NPU, we need to detect the device type as part of presence detection, which can't happen until well after the point where the HDAT or platform code has created the NPU device tree nodes. Changing a node's compatible string after it's been created is a bit ugly, so instead we should move the device type to a new property which we can add to the node later on. Get rid of the ibm,npu-link-opencapi compatible string, add a new ibm,npu-link-type property, and a helper function to check the link type. Add an "unknown" device type in preparation for later patches to detect device type dynamically. These device tree bindings are entirely internal to skiboot and are not consumed directly by Linux, so this shouldn't break anything (other than internal BML lab environments).

2018-06-18NX: Add NX coprocessor init opal callHaren Myneni1-0/+36
The read offset (4:11) in Receive FIFO control register is incremented by FIFO size whenever CRB read by NX. But the index in RxFIFO has to match with the corresponding entry in FIFO maintained by VAS in kernel. VAS entry is reset to 0 when opening the receive window during driver initialization. So when NX842 is reloaded or in kexec boot, possibility of mismatch between RxFIFO control register and VAS entries in kernel. It could cause CRB failure / timeout from NX. This patch adds nx_coproc_init opal call for kernel to initialize readOffset (4:11) and Queued (15:23) in RxFIFO control register.

2018-03-01phb4: set PBCQ Tunnel BAR for tunneled operationsPhilippe Bergheaud1-0/+76
P9 supports PCI tunneled operations (atomics and as_notify) that are initiated by devices. A subset of the tunneled operations require a response, that must be sent back from the host to the device. For example, an atomic compare and swap will return the compare status, as swap will only performed in case of success. Similarly, as_notify reports if the target thread has been woken up or not, because the operation may fail. To enable tunneled operations, a device driver must tell the host where it expects tunneled operation responses, by setting the PBCQ Tunnel BAR Response register with a specific value within the range of its BARs. This register is currently initialized by enable_capi_mode(). But, as tunneled operations may also operate in PCI mode, a new API is required to set the PBCQ Tunnel BAR Response register, without switching to CAPI mode. This patch provides two new OPAL calls to get/set the PBCQ Tunnel BAR Response register. Note: as there is only one PBCQ Tunnel BAR register, shared between all the devices connected to the same PHB, only one of these devices will be able to use tunneled operations, at any time.
