* firewire: Clean up comment style.Kristian Høgsberg2007-05-101-2/+2
| | | | | | | | 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)
* firewire: Move sync and tag parameters to start_iso ioctl.Kristian Høgsberg2007-03-151-8/+4
| | | | | | | | | 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>
* firewire: adjust whitespaceStefan Richter2007-03-091-1/+1
| | | | | | | Remove space before tab and trailing whitespace. Unify indentation of goto target labels. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

* firewire: Configure channel and speed at context creation time.Kristian Høgsberg2007-03-091-6/+5
| | | | | | | | 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>
* firewire: Get zeroed out pages for mapping to user space.Kristian Høgsberg2007-03-091-1/+1

* firewire: Use a buffer fill descriptor for receive when header size is 0.Kristian Høgsberg2007-03-091-1/+1
| | | | | | | | | 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.

* firewire: Split the iso buffer out from fw_iso_context and avoid vmalloc.Kristian Høgsberg2007-03-091-52/+66
| | | | | | | | | | 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.
