2007-04-12firewire: Byteswap iso header so all headers are presented as be32.Kristian Høgsberg1-1/+7

2007-03-28firewire: Increase the number of config rom retries and the retry delay.Kristian Høgsberg1-2/+2
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. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-28firewire: Don't set card->irm_node before we have a new valid topology.Kristian Høgsberg1-3/+4
In case the topology build fails, we want to retain the old topology info until another reset finishes and results in a valid new tree. If we clear card->irm_node to NULL and the topology build fails, we end up dereferencing a NULL pointer in a few places.

2007-03-28firewire: Generalize resource tracking for cdev implementation.Kristian Høgsberg2-119/+119
Generalize the way we keep track of the various resources and assign a unique handle to each resource. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-28firewire: Add ioctls to add and remove config rom descriptors.Kristian Høgsberg3-5/+114
Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> (fixed whitespace)
2007-03-28firewire: Streamline userspace interface structs.Kristian Høgsberg2-11/+31
Make event struct layout common part include the closure and add a union for all event types; provide a mechanism for setting the bus reset event closure. Shuffle struct fw_cdev_queue_iso fields around to be 64-bit safe. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-28firewire: Remember to set the driver_data pointer when queueing a packet.Kristian Høgsberg1-0/+1
Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-28firewire: Use device->groups for adding device attributes.Kristian Høgsberg2-35/+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>
2007-03-25firewire: Add phy register defines.Marc Butler2-4/+16

2007-03-22firewire: Export GUID as sysfs attribute.Kristian Høgsberg1-2/+13
Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-22firewire: Add sysfs attributes for config rom directory values.Kristian Høgsberg1-4/+147
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 Høgsberg1-57/+36
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>
2007-03-21firewire: ROM cache is CPU-endianStefan Richter1-1/+1

2007-03-21firewire: add includes for sem and rw_semStefan Richter1-0/+2
as a precaution. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-21firewire: Grab dev->sem when doing the update callback.Kristian Høgsberg1-1/+4
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>
2007-03-21firewire: rename CONFIG_FW to CONFIG_FIREWIREStefan Richter3-9/+9

2007-03-15firewire: Move sync and tag parameters to start_iso ioctl.Kristian Høgsberg5-32/+26
Setting these at create_context time or start_iso time doesn't matter much, but raw1394 sets them at start_iso time so that will be easier to emulate this way. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-15firewire: Fix dualbuffer iso receive mode and drop buffer fill mode.Kristian Høgsberg2-122/+66
The dualbuffer DMA setup did not account for the iso trailer word and thus didn't work correctly. With this fixed we can drop the dual buffer fallback mode. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

2007-03-10firewire: Track pending transactions and cancel them on cdev release.Kristian Høgsberg1-3/+20
Without this, pending transactions will dereference freed memory if they complete after the device file has been closed. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-10firewire: Move async transmit to use the general context code.Kristian Høgsberg2-214/+149
The old async transmit context handling was starting and stopping DMA for every packet transmission. This could cause silently failing packet transmission, if the DMA was reprogrammed too close to being stopped. The general context code keeps DMA running at all times and fixes this problem. It's also a nice cleanup. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-10firewire: Use only a wait queue and terminate poll and read on device removal.Kristian Høgsberg3-29/+59
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>
2007-03-10firewire: Don't time out command orbs, leave that to the scsi stack.Kristian Høgsberg1-20/+11
The mod_timer based timing out of orb was a little to agressive and would time out legit, but long-lived scsi cmds. Besides, the scsi stack keeps track of this already. Since we're only timing out management orbs, go back to wait_for_completion_timeout. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

2007-03-10firewire: Switch cdev code over to use register_chrdev and keep a list of ↵Kristian Høgsberg4-22/+51
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>
2007-03-10firewire: Generalize get_config_rom to get_info.Kristian Høgsberg2-21/+75
Repurpose the get_config_rom ioctl to a general get_info ioctl. This ioctl is now used for version negotiation, and optionally returns the config rom, and the current bus info. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

2007-03-10firewire: Clear all interrupt bits before shutting down.Kristian Høgsberg1-1/+2
Some flaky controllers doesn't honor the masterIntEnable bits and can generate bus reset events even if that bit is cleared. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
