RDMA/core: Add iWARP protocol statistics attributes in sysfs

2008-07-15T06:48:48Z

This patch adds a sysfs attribute group called "proto_stats" under /sys/class/infiniband/$device/ and populates this group with protocol statistics if they exist for a given device. Currently, only iWARP stats are defined, but the code is designed to allow InfiniBand protocol stats if they become available. These stats are per-device and more importantly -not- per port. Details: - Add union rdma_protocol_stats in ib_verbs.h. This union allows defining transport-specific stats. Currently only iwarp stats are defined. - Add struct iw_protocol_stats to define the current set of iwarp protocol stats. - Add new ib_device method called get_proto_stats() to return protocol statistics. - Add logic in core/sysfs.c to create iwarp protocol stats attributes if the device is an RNIC and has a get_proto_stats() method.

IB: convert struct class_device to struct device

2008-04-20T02:10:30Z

This converts the main ib_device to use struct device instead of struct class_device as class_device is going away. Signed-off-by: Tony Jones Signed-off-by: Kay Sievers Cc: Roland Dreier Cc: Sean Hefty Cc: Hal Rosenstock Signed-off-by: Greg Kroah-Hartman

IB: Fix return value in ib_device_register_sysfs()

2008-02-15T23:05:05Z

If kobject_create_and_add() fails and returns NULL, the current code in ib_device_register_sysfs() does not set ret and hence returns 0. Set ret to -ENOMEM for this failure, so that the caller knows that ib_device_register_sysfs() actually failed. Signed-off-by: Li Zefan Signed-off-by: Roland Dreier

Kobject: convert drivers/* from kobject_unregister() to kobject_put()

2008-01-25T04:40:40Z

There is no need for kobject_unregister() anymore, thanks to Kay's kobject cleanup changes, so replace all instances of it with kobject_put(). Cc: Kay Sievers Signed-off-by: Greg Kroah-Hartman

Kobject: change drivers/infiniband to use kobject_init_and_add

2008-01-25T04:40:26Z

Stop using kobject_register, as this way we can control the sending of the uevent properly, after everything is properly initialized. Cc: Roland Dreier Cc: Sean Hefty Cc: Hal Rosenstock Cc: Kay Sievers Signed-off-by: Greg Kroah-Hartman

Driver core: change add_uevent_var to use a struct

2007-10-12T21:51:01Z

This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.

sysfs: kill unnecessary attribute->owner

2007-07-11T23:09:06Z

sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded. For more info regarding lifetime rule cleanup, please read the following message. http://article.gmane.org/gmane.linux.kernel/510293 (tweaked by Greg to not delete the field just yet, to make it easier to merge things properly.)

IB/core: Take sizeof the correct pointer when calling kmalloc()

2007-07-10T18:04:40Z

When allocating out_mad in show_pma_counter(), take sizeof *out_mad instead of sizeof *in_mad. It is true that today the type of in_mad and out_mad are the same, but this patch will give us a cleaner code. Signed-off-by: Dotan Barak Signed-off-by: Roland Dreier
