enclosure: fix WARN_ON removing an adapter in multi-path devices

2015-03-31T05:53:36Z

We have peculiar problems with multi-path and enclosures: physically, we know each bay can only be occupied by a single disk device. However in multi-path, it appears we have many (because each path to the device appears in Linux as a different kernel device). We try to fix this by only having the last seen device show up in the bay. Sysfs gets very annoyed if we try to manipulate links when the kobject sysfs directory (kobj.sd) doesn't exist and drops a huge WARN_ON which most users panic and report an oops for. This happens on a few path removal situations and IBM reports seeing it when one of their multi-path adapters is removed. Add a check to enclosure device removal for the existence the sysfs directory containing both the forward and back links so that the remnants (if any) get removed in either direction but no scary warnings are dumped.

mei: make device disabled on stop unconditionally

2015-03-02T03:34:50Z

Set the internal device state to to disabled after hardware reset in stop flow. This will cover cases when driver was not brought to disabled state because of an error and in stop flow we wish not to retry the reset.

cxl: Add missing return statement after handling AFU errror

2015-02-06T00:17:27Z

We were missing a return statement in the PSL interrupt handler in the case of an AFU error, which would trigger an "Unhandled CXL PSL IRQ" warning. We do actually handle these type of errors (by notifying userspace), so add the missing return IRQ_HANDLED so we don't throw unecessary warnings.

cxl: Fail AFU initialisation if an invalid configuration record is found

2015-02-06T00:16:58Z

If an AFU claims to have a configuration record but doesn't actually contain a vendor and device ID, fail the AFU initialisation. Right now this is just a way of politely letting AFU developers know that they need to fix their config space, but later on we may expose the AFUs as actual PCI devices in their own right and don't want to inadvertendly expose an AFU with a bad config space.

cxl: Export optional AFU configuration record in sysfs

2015-02-06T00:16:56Z

An AFU may optionally contain one or more PCIe like configuration records, which can be used to identify the AFU. This patch adds support for exposing the raw config space and the vendor, device and class code under sysfs. These will appear in a subdirectory of the AFU device corresponding with the configuration record number, e.g. cat /sys/class/cxl/afu0.0/cr0/vendor 0x1014 cat /sys/class/cxl/afu0.0/cr0/device 0x4350 cat /sys/class/cxl/afu0.0/cr0/class 0x120000 hexdump -C /sys/class/cxl/afu0.0/cr0/config 00000000 14 10 50 43 00 00 00 00 06 00 00 12 00 00 00 00 |..PC............| 00000010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00000100 These files behave in much the same way as the equivalent files for PCI devices, with one exception being that the config file is currently read-only and restricted to the root user. It is not necessarily required to be this strict, but we currently do not have a compelling use-case to make it writable and/or world-readable, so I erred on the side of being restrictive.
