* Only add presence watching when all OCCs are boundEddie James2017-12-203-5/+24
| | | | | | | | | | | | The OCC present count returns the number of OCCs in the system. Before we have bound the second OCC, this will be greater than the number of OCCs the Manager has counted as Active, resulting in a mismatch, causing an error.

* Create OCC objects on app startupDeepak Kodihalli2017-12-041-19/+3
| | | | | | | | | | | | | | | | | | Previously OCC objects would be created either in response (D-Bus signals) to CPU inventory objects being created, or if the CPU objects were already present when the openpower-occ-control app starts. We've had few issues where it has seemed like the OCC objects never got created, or did not get created in time; the CPU objects were created though. This is suggestive of either a race, or the D-Bus signal being missed altogether. Simplify by creating OCC objects when the app starts (we know how many OCC objects to create based on system specific config), instead of doing it reactively. The OCC objects will be marked active only when we're sent a sensor from the host asking to do so. That's not changing.

* Add OCC present count detection and watchEdward A. James2017-11-1711-25/+190
| | | | | | | | | | | | | | | | Add a Presence child class of Error to handle detecting the number of OCCs available. Add an instance of this Presence class if the Device detects that it is the master OCC, since the number of present OCCs is only reported by the master OCC. When a change to the number of OCCs reported is detected, compare with the number of OCCs determined to be active by the Manager, and if there is a mismatch, follow the usual error path (reset OCC, etc).

* Add additional device bind case if occActive is out-of-syncEdward A. James2017-11-081-0/+21
| | | | | | | | | | | | | This happens with bmc reboot if the host is up. BMC comes back up and initial fsi load binds the first proc occ-hwmon device. OCC controller starts and see's its bound, so occActive goes true. FSI rescan occurs since host is up, unloading the first proc occ-hwmon device... Now we can't enable it again since occActive is still true. Resolves openbmc/openbmc#2325 Change-Id: Iac838bc51d1110f502ca0c7c5da78dc5e1780c98 Signed-off-by: Edward A. James <eajames@us.ibm.com>

* Add occ_ prefix for i2c occ dbus objectsLei YU2017-10-264-6/+22
| | | | | | | | | | | | | | I2c occ dbus objects path were their i2c addresses, e.g. 3_0050. This does not indicate it's occ objects, and it does not work with op-occ-disable/enable services, which searches "occ" key words in object path. So add "occ_" prefix for i2c occ dbus objects, e.g. occ_3_0050, to indicate it's occ objects and work well with op-occ-disable/enable services.

* Always watch for CPU inventory creationDeepak Kodihalli2017-10-251-15/+13
| | | | | | | | | | | | | | | | | | Previously the app would watch for CPU inventory being created (in order to create OCC objects) only if no CPU inventory existed when the app starts. This logic breaks when some of the CPUs exist out of the max possible, because we would never watch for those missing CPU objects being potentially created in the next boot. Instead, always watch for CPU inventory being created via the d-bus InterfacesAdded signal. This is safe in case a persisted CPU object existed in the inventory, because the signal would not fire on that object. Resolves openbmc/openbmc#2515.

* Check only CPU presence before reconstructing OCCsDeepak Kodihalli2017-10-251-6/+1
| | | | | | | | | | | | | | | | OCC d-bus objects are typically created in response to the CPU inventory being created. At this point of time we just know the CPU is present. It may not be functional. Of course if the CPU is not functional, then the host may or may not choose to set the OCC active, but the OCC object must have been created in response to a present CPU. This commit employs the same logic for reconstructing OCC objects when the OCC app restarts. Previously an OCC object would be created only if corresponding CPU is present and functional. Instead, check only for presence. Change-Id: I4f85a644237b5b5aa7dc3e52d266375b786a8c0a Signed-off-by: Deepak Kodihalli <dkodihal@in.ibm.com>

* Set OccActive property on application startVishwanatha Subbanna2017-09-263-3/+24
| | | | | | | | | | | | | | | | | | | | | Host sends OCC active status command just once as part of power on operation and when that is sent, occ control application binds the device. As part of bind, a sysfs file gets created that would be used to communicate the occ error status back to user. If occ control application terminates and restarts, then it needs some way to set OccActive property and this commit adds that support. Solution is to check if the device is already bound by checking the presence of the OCC_HWMON_PATH/occ<number>-dev0 and set the property if found Fixes openbmc/openbmc#2238 Change-Id: I920b52e3970cc91af50b5bc68ead44c66eab8944 Signed-off-by: Vishwanatha Subbanna <vishwa@linux.vnet.ibm.com>

* Change signature of getServiceVishwanatha Subbanna2017-09-012-5/+5
| | | | | | | | | | | | | getService() has [bus, interface, path] as parameter and the caller invoked it with [bus, path, interface] and that resulted in a failure. Although the fix can be put into the caller to pass the right arguments, better fix would be to change the signature of getService() to receive path and then the interface as that is what has been followed all over and the deviation resulted in this bug.

* Add I2C OCC support for P8 systemsLei YU2017-08-288-4/+211
| | | | | | | | | | | | | | P8 system uses I2C OCC and it uses different driver for occ-hwmon. Add `--enable-i2c-occ` configure option to enable the support. It searches i2c device names in sysfs to get all occ-hwmon devices and use the i2c device name to bind/unbind the driver. The occ control object path for I2C OCC hwmon becomes something like /org/open_power/control/3_0050, where 3_0050 is the i2c address.

| | | | | | | | | | | | | | | OCC control application looks at CPU inventory and creates D-Bus objects.

* Populate device entry based on positionVishwanatha Subbanna2017-04-172-2/+10
| | | | | | | | | | | | | | | | | | | | Communicating to OCC from BMC in PassThrough mode involves 2 drivers, namely; 1) SBE FIFO driver --> Used to communicate with SBE 2) OCC driver --> Which uses FIFO driver to write data to OCC at a predefined address and reads it back from a predefined OCC address. Device entry that is of interest here belongs to #2 above. This will map occ0 to fifo1, occ2 to fifo2 and so on. Until the udev rules are in place to make sure that a particular entry always maps to correct device not caring the probing order, this change here is a best guess that cpu0 and cpu1 would mostly in all cases be probed in that order.
