2007-07-10firewire: simplify a struct typeStefan Richter2-30/+24
cleanup after "firewire: support S100B...S400B and link slower than PHY" Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Kristian Høgsberg <krh@redhat.com>
2007-07-10firewire: support S100B...S400B and link slower than PHYStefan Richter5-16/+45
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>
2007-07-10firewire: optimize gap count with 1394b leaf nodesStefan Richter4-17/+14
Table-based gap count optimization cannot be used if 1394b repeater PHYs are present. But it does work with 1394b leaf nodes. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Kristian Høgsberg <krh@redhat.com>

2007-07-10firewire: missing newline in printkStefan Richter3-5/+5
Also remove some errno printouts which will be shown by infrastructure code anyway. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

cleanup after support of single-buffer requests was dropped Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Kristian Hoegsberg <krh@redhat.com>
2007-06-29firewire: add Kconfig help on building both stacksStefan Richter1-22/+43
Alas that won't work so good, because nobody reads help texts. I thought about adding some crude multiple choice selection (build the old stack, build the new stack, build both stacks). It's possible, but it would introduce awkward dummy config variables. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

This patch fixes an OOPS on cdev release for an fd where iso context creation failed. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

2007-05-31firewire: Change struct fw_cdev_iso_packet to not use bitfields.Kristian Høgsberg1-1/+16
The struct is part of the userspace interface and can not use bitfields. This patch replaces the bitfields with a __u32 'control' word and provides access macros to set the bits. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-05-31firewire: Implement suspend/resume PCI driver hooks.Kristian Høgsberg2-69/+123
It's a low-impact design, that just makes suspend/resume look like a bus reset to the upper level drivers, but it should be sufficient. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-05-31firewire: fw-sbp2: implement sysfs ieee1394_idStefan Richter2-0/+54
The attribute /sys/bus/scsi/devices/*:*:*:*/ieee1394_id, as generated by the old sbp2 driver, is typically used to create persistently named links in /dev/disk/by-id. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Kristian Høgsberg <krh@redhat.com>

2007-05-27firewire: prefix modules with firewire- instead of fw-Stefan Richter2-12/+14
Of course everybody immediately associates "fw-" with FireWire, not firmware or firewall or whatever. But "firewire-" has a nice ring to it too. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Acked-by: Kristian Hoegsberg <krh@bitplanet.net>

2007-05-10firewire: Provide module aliase for backwards compatibility.Olaf Hering2-0/+10
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>

2007-04-12firewire: Only free ORBs that completed the initial transaction.Kristian Høgsberg1-1/+4
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.

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.

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.
