Puts a stray endian annotation down. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-20firewire: fix compiler warnings on 64bitStefan Richter

2007-03-20firewire: add includes for sem and rw_semStefan Richter
as a precaution. 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>
2007-03-20firewire: rename CONFIG_FW to CONFIG_FIREWIREStefan Richter

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>
2007-03-09firewire: Implement CSR cycle time and bus time registers.Kristian Høgsberg

Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-09firewire: Add generation field to send_request ioctl struct.Kristian Høgsberg
Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-09firewire: Add card index field to get_info cdev ioctl struct.Kristian Høgsberg
Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-09firewire: Fix order of arguments for iso context creation.Kristian Høgsberg
Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-09firewire: Track pending transactions and cancel them on cdev release.Kristian Høgsberg
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>
2007-03-09firewire: Move async transmit to use the general context code.Kristian Høgsberg
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>
2007-03-09firewire: 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: Don't time out command orbs, leave that to the scsi stack.Kristian Høgsberg
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>
2007-03-09firewire: Add rom_index attribute for unit sysfs directories.Kristian Høgsberg

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: Generalize get_config_rom to get_info.Kristian Høgsberg
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>
2007-03-09firewire: Implement ioctl to initiate bus reset.Kristian Høgsberg

2007-03-09firewire: Only use INIT_DELAYED_WORK for first initialization.Kristian Høgsberg

2007-03-09firewire: Iterate through units in a keventd callback for update callbacks.Kristian Høgsberg
We can't take the klist lock for the child device list in interrupt context. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-09firewire: Clear all interrupt bits before shutting down.Kristian Høgsberg
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>
2007-03-09firewire: Drop the unused fw_card device.Kristian Høgsberg

2007-03-09firewire: Let an fw_descriptor specify a leading immediate key/value pair.Kristian Høgsberg
This lets us break out "Juju" as the model name in the config rom. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-09firewire: Scheduled removal of SA_xxx interrupt flags fixups 3Thomas Gleixner
The obsolete SA_xxx interrupt flags have been used despite the scheduled removal. Fixup the remaining users in -mm.

2007-03-09firewire: Configure channel and speed at context creation time.Kristian Høgsberg
We need the channel number as we queue up iso packets for transmission so we can fill out the header correctly. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-09firewire: Store OHCI version and make sure we have at least 1.1 before doing ↵Kristian Høgsberg
dualbuffer. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

2007-03-09firewire: Don't touch DMA descriptors after appending.Kristian Høgsberg
When a DMA descriptor is appended to the context we sync it for DMA and the device might potentially read it immediately. So, we can't set the IRQ bits in the descriptor after appending. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-09firewire: Use a buffer fill descriptor for receive when header size is 0.Kristian Høgsberg
When the DMA is setup to not strip any headers, we need to use the buffer fill descriptor instead of the dual buffer, since the dual buffer descriptor must strip a non-zero number of header quadlets. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-09firewire: Set correct buffer lengths for dualbuffer DMA descriptor.Kristian Høgsberg

2007-03-09firewire: Generalize the iso transmit descriptor buffer logic.Kristian Høgsberg
The descriptor circular buffer logic used for iso transmission is useful for async transmit too, so pull the sharable logic out in a few standalone functions. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-09firewire: Split the iso buffer out from fw_iso_context and avoid vmalloc.Kristian Høgsberg
This patch splits out the iso buffer so we can initialize it at mmap time with the size provided in the mmap call. Furthermore, allocate the backing pages using alloc_page to avoid setting up kernel side virtual memory mappings for the pages.
