2007-05-10firewire: Drop single buffer request support.Kristian Høgsberg
The SCSI layer only passes sg requests down, so drop the use_sg == 0, request_bufflen != 0 case. Signed-off-by: Kristian Hoegsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

2007-05-10firewire: Allocate scsi_host up front and allocate the sbp2_device as hostdata.Kristian Høgsberg
Avoids an extra allocation and simplifies lifetime rules for the scsi_host. Signed-off-by: Kristian Hoegsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-05-10firewire: Provide module aliase for backwards compatibility.Olaf Hering
This patch loads fw-sbp2 if sbp2 is still in the config file. So one can go back and forth between releases without worry about the root filesystem drivers. Signed-off-by: Kristian Hoegsberg <krh@redhat.com> Existing mkinitrd scripts still have to be adapted, unless they grok module aliases. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-05-10firewire: Add to fw-core-y instead of assigning fw-core-objs in Makefile.Kristian Høgsberg

2007-05-10firewire: Clean up comment style.Kristian Høgsberg
Drop filenames from file preamble, drop editor annotations and use standard indent style for block comments. Signed-off-by: Kristian Hoegsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> (fixed typo)
2007-05-10firewire: Use lib/ implementation of CRC ITU-T.Kristian Høgsberg
With the CRC ITU-T implementation available in lib/ we can use that instead. This also fixes a bug in the topology map crc computation. Signed-off-by: Kristian Hoegsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> (fixed Kconfig)
2007-05-10CRC ITU-T V.41Ivo van Doorn
This will add the CRC calculation according to the CRC ITU-T V.41 to the kernel lib/ folder. This code has been derived from the rt2x00 driver, currently found only in the wireless-dev tree, but this library is generic and could be used by more drivers who currently use their own implementation. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Also useful for the new firewire stack. Signed-off-by: Kristian Hoegsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-04-30firewire: Future proof the iso ioctls by adding a handle for the iso context.Kristian Høgsberg
Currently create context always returns 0 and the other iso ioctls will expect user space to pass that in for subsequent ioctls. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-04-30firewire: Add read/write and size annotations to IOC numbers.Kristian Høgsberg
Also, with this change, refactor ioctl dispatch code to do the copying from and to user space as indicated by the IOC annotations. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-04-27firewire: don't use extern on public symbolsRandy Dunlap

2007-04-12firewire: Do an agent reset on error recovery.Kristian Høgsberg
Signed-off-by: Kristian Høgsberg <krh@redhat.com> (Reverted part which moved it from eh_abort_handler to eh_host_reset_handler) Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-04-12firewire: Only free ORBs that completed the initial transaction.Kristian Høgsberg
In some situations we can receive the ORB status write before we have received the ORB pointer write response. When this happens, we assume that the fw_transaction is finished and free the ORB struct containing the fw_transaction. This fix make the status write logic only accept status writes for ORBs where the initial ORB pointer write transaction finished. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-04-12firewire: Forward SAM status codes to the scsi stack.Kristian Høgsberg

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. 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 Høgsberg
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. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-28firewire: Generalize resource tracking for cdev implementation.Kristian Høgsberg

2007-03-28firewire: Streamline userspace interface structs.Kristian Høgsberg
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: 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. 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 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>

2007-03-15firewire: Move sync and tag parameters to start_iso ioctl.Kristian Høgsberg
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 Høgsberg
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>
