* firewire: enforce access order between generation and node ID, fix "giving ↵Stefan Richter2008-01-30
| | | | | | | | | | | | | | | | | | | | | up on config rom" fw_device.node_id and fw_device.generation are accessed without mutexes. We have to ensure that all readers will get to see node_id updates before generation updates. Fixes an inability to recognize devices after "giving up on config rom", https://bugzilla.redhat.com/show_bug.cgi?id=429950 Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Reviewed by Nick Piggin <nickpiggin@yahoo.com.au>. Verified to fix 'giving up on config rom' issues on multiple system and drive combinations that were previously affected.

* firewire: support S100B...S400B and link slower than PHYStefan Richter2007-07-09
| | | | | | | | | | | | | | | | | Use a speed probe to determine the speed over 1394b buses and of nodes which report a link speed less than their PHY speed. Log the effective maximum speed of newly created nodes in dmesg. Also, read the config ROM (except bus info block) at the maximum speed rather than S100. This isn't a real optimization though because we still only use quadlet read requests for the entire ROM. The patch also adds support for S1600 and S3200, although such hardware does not exist yet.

* firewire: fw-sbp2: implement sysfs ieee1394_idStefan Richter2007-05-31
| | | | | | | | | The attribute /sys/bus/scsi/devices/*:*:*:*/ieee1394_id, as generated by the old sbp2 driver, is typically used to create persistently named links in /dev/disk/by-id. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Kristian Høgsberg <krh@redhat.com>

* firewire: Use device->groups for adding device attributes.Kristian Høgsberg2007-03-28
| | | | | | | | | We dynamically create an attribute group for the key present on the device in hand and point device->group to it. This way the device core adds the sysfs attributes for us as the device is added. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

* firewire: Use only a wait queue and terminate poll and read on device removal.Kristian Høgsberg2007-03-09
| | | | | | | | | Drop the event list semaphore and only use the wait queue and the list to synchronize queue access. Break out of a poll or read whenever the device is disconnected. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

* firewire: mark some structs constStefan Richter2007-03-09
| | | | | | | | | | | | Instances of struct file_operations and struct fw_card_driver can be qualified as "const". Ditto with struct fw_descriptor.data, struct fw_device_id, and predefined instances of struct fw_address_region, at least in the current implementation. Data qualified as const is placed into the .rodata section which won't be mixed with dirty data. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
