2007-07-10firewire: support S100B...S400B and link slower than PHYStefan Richter
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. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Kristian Høgsberg <krh@redhat.com>

2007-03-28firewire: Increase the number of config rom retries and the retry delay.Kristian Høgsberg
Some devices have a really long power-on cycle, and we fail to successfully probe these if they're plugged in and then turned on. There's really no down-side to bumping the number of retries and the retry delay, and most devices will get picked up within the first couple of retries anyway.

2007-03-28firewire: Use device->groups for adding device attributes.Kristian Høgsberg
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.

2007-03-22firewire: Add sysfs attributes for config rom directory values.Kristian Høgsberg
We export the entire config rom, so this is technically redundant, but should make udev rules and HAL integration easier. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-22firewire: Make use of struct device_type.Kristian Høgsberg
The device_type struct is useful for setting attributes for a device and overriding .release and .uevent for a group of devices. This patch uses it this way to clean up the sysfs code a bit. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

2007-03-20firewire: Grab dev->sem when doing the update callback.Kristian Høgsberg
This serializes the update callback with the probe and remove callback from the driver core and prevents remove from being called while update is running for the same device. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-09firewire: Use only a wait queue and terminate poll and read on device removal.Kristian Høgsberg
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>

2007-03-09firewire: Switch cdev code over to use register_chrdev and keep a list of ↵Kristian Høgsberg
devices. The old mechanism kept a struct cdev for each fw device, but fops->release would reference this struct after the device got freed in some cases. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

2007-03-09firewire: consistent usage of node_idStefan Richter
Definitions as per IEEE 1212 and IEEE 1394: Node ID: Concatenation of bus ID and local ID. 16 bits long. Bus ID: Identifies a particular bus within a group of buses interconnected by bus bridges. Local ID: Identifies a particular node on a bus. PHY ID: Local ID of IEEE 1394 nodes. 6 bits long. Never ever use a variable called node_id for anything else than a node ID.

2007-03-09firewire: mark some structs constStefan Richter
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>
