| * [SCSI] Make scsi_host_template::proc_name const char * instead of char *.Kristian Høgsberg2007-07-191-1/+1

* | firewire: fix memory leak of fw_request instancesStefan Richter2007-07-182-1/+7
| | | | | | | | | | | | | | | | Found and debugged by Jay Fenlason <fenlason@redhat.com>. The bug was especially noticeable with direct I/O over fw-sbp2. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Kristian Høgsberg <krh@redhat.com>
* | firewire: remove bogus check in fw_core_handle_requestStefan Richter2007-07-181-5/+0
| | | | | | | | | | | | | | | | | | | | | | This check is bogus: - Maximum asynchronous payload size for S800...S3200 is 4096. - The p->payload_length is totally uninteresting. Only the request->length of the subsequently allocated and initialized struct fw_request is of significance.

* firewire: fw-sbp2: fix DMA mapping of S/G tablesStefan Richter2007-07-101-11/+8
| | | | | | | | | - The CPU must not touch the buffer after it was DMA-mapped. - The size argument of dma_unmap_single(...page_table...) was bogus. - Move a comment closer to the code to which it refers to.

* firewire: fw-sbp2: add a boundary checkStefan Richter2007-07-101-0/+5
| | | | | | | | | | | | | | Add rudimentary check for the case that the page table overflows due to merging of s/g elements by the IOMMU. This would have lead to overwriting of arbitrary memory. After this change I expect that an offending command will be unsuccessfully retried until the scsi_device is taken offline by SCSI core. It's a border case and not worth to implement a recovery strategy. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Acked-by: Kristian Høgsberg <krh@redhat.com>

* firewire: fw-sbp2: correctly dereference by container_ofJay Fenlason2007-07-101-2/+3
| | | | | | | | | Replace a cast with a container_of(). As long as nobody reorders the structure elements, they do the same thing, but container_of() is more readable. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> (added complete_command_orb) Acked-by: Kristian Høgsberg <krh@redhat.com>

* firewire: fw-sbp2: let SCSI shutdown commands through before logoutStefan Richter2007-07-101-4/+2
| | | | | | | | This affects of course only the "soft shutdown" case, e.g. "modprobe -r firewire-sbp2", while it doesn't matter for hot unplug. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Kristian Høgsberg <krh@redhat.com>
* firewire: fw-sbp2: implement max sectors limit for some old bridgesStefan Richter2007-07-101-1/+3
| | | | | | | This currently only affects one bridge in the hardwired blacklist. I don't own one of those, hence haven't tested it. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

* firewire: support S100B...S400B and link slower than PHYStefan Richter2007-07-105-16/+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.

* firewire: optimize gap count with 1394b leaf nodesStefan Richter2007-07-104-17/+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>

* firewire: add Kconfig help on building both stacksStefan Richter2007-06-291-22/+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.

* firewire: Change struct fw_cdev_iso_packet to not use bitfields.Kristian Høgsberg2007-05-311-1/+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.

* firewire: Implement suspend/resume PCI driver hooks.Kristian Høgsberg2007-05-312-69/+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>
* firewire: fw-sbp2: implement sysfs ieee1394_idStefan Richter2007-05-312-0/+54

* firewire: prefix modules with firewire- instead of fw-Stefan Richter2007-05-272-12/+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>
