* [SCSI] spi transport: don't allow dt to be set on SE or HVD busesJames Bottomley2006-06-10
| | | | | | | | This is really just a belt and braces test. The standards require disks to respond DT not capable on a non-LVD bus ... however, not all disks follow the standards ... Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] drivers/scsi: Use ARRAY_SIZE macroTobias Klauser2006-06-10
| | | | | | | | | Use ARRAY_SIZE macro instead of sizeof(x)/sizeof(x[0]) and remove duplicates of the macro. Signed-off-by: Tobias Klauser <tklauser@nuerscht.ch> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] fix minor problem in spi transport message functionsJames Bottomley2006-03-12
| | | | | | The check for a one byte message should be msg[0] == 0x55 not msg == 0x55 Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] Missing names from SPI3, SPI4 and SPI5Matthew Wilcox2006-03-12
| | | | | | | | | | | | | | | | | | | | | | | Add several missing messages from SPI3, SPI4 and SPI5: - Terminate Process - Continue Task - Target Transfer Disable - Clear ACA - LUN Reset - ACA - QAS Request Rename some older commands to their SPI5 names: - Command Complete -> Task Complete - Abort -> Abort Task Set - Bus device Reset -> Target Reset - Clear Queue -> Clear Task Set Change spi_print_msg() to always consume one byte, even if we don't recognise it. That allows drivers to call it in a loop to print all messages. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] Improve message printing codeMatthew Wilcox2006-02-28
| | | | | | | | | | Fix a bug where we would consume one byte too many in the message printing code. Add support for 256-byte long messages. Add support for the Modify Bidirectional Data Pointer message. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* [SCSI] Make spi_print_msg more consistentMatthew Wilcox2006-02-27
| | | | | | | | Almost all the output from spi_print_msg() has a trailing space. This patch fixes up the three cases that don't. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] Add spi_populate_*_msg functionsMatthew Wilcox2006-02-27
| | | | | | | | | | | | Introduce new helpers: - spi_populate_width_msg() - spi_populate_sync_msg() - spi_populate_ppr_msg() and use them in drivers which already enable the SPI transport. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* [SCSI] Add PPR support to spi_print_msgMatthew Wilcox2005-12-15
| | | | | | | | | Introduce a new helper, print_nego() to handle SDTR/WDTR/PPR. Split out the guts of show_spi_transport_period_helper() into period_to_str() and use it in print_nego to get the period factor conversion right.

* [SCSI] Use ARRAY_SIZE in spi_print_msgMatthew Wilcox2005-12-15
| | | | | | | | Replace the custom NO_*_MSGS definitions with uses of ARRAY_SIZE. This fixes a bug in the definition of NO_EXTENDED_MSGS. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] Fix printing of two-byte messagesMatthew Wilcox2005-12-15

* [SCSI] Rename scsi_print_msg to spi_print_msgMatthew Wilcox2005-12-15

* [SCSI] Move scsi_print_msg to SPI classMatthew Wilcox2005-12-15
| | | | | | | | | scsi_print_msg() is an SPI-specific concept. This patch moves it from constants.c to scsi_transport_spi.c and updates the Kconfig to link in the SPI class for the drivers which use scsi_print_msg().

* [SCSI] Delete trailing full stopMatthew Wilcox2005-12-13
| | | | | | | | None of the other domain validation messages have a trailing full stop, so I don't see why this one should. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] SPI DV: be more conservative about echo buffer usageJames Bottomley2005-12-01
| | | | | | | | | | | Some SCSI devices apparently get very confused if we try to use the echo buffer on a non-DT negotiated bus (this mirrors the problems of using PPR on non-LVD for some devices). The fix is to be far more conservative about when we use an echo buffer. With this patch, we'll now see what parameters are negotiated by the read only test, and only look for an echo buffer if DT is negotiated.

* [SCSI] move the mid-layer printk's over to shost/starget/sdev_printkJames Bottomley2005-10-28
| | | | | | | | | This should eliminate (at least in the mid layer) to make numeric assumptions about any of the enumeration variables. As a side effect, it will also make all the messages consistent and line us up nicely for the error logging strategy (if it ever shows itself again).

* [SCSI] convert SPI transport class to scsi_executeJames Bottomley2005-08-28
| | | | | | | | | | | This one's slightly more difficult. The transport class uses REQ_FAILFAST, so another interface (scsi_execute) had to be invented to take the extra flag. Also, the sense functions are shifted around to allow spi_execute to place data directly into a struct scsi_sense_hdr. With this change, there's probably a lot of unnecessary sense buffer allocation going on which we can fix later. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] correct transport class abstraction to work outside SCSIJames Bottomley2005-08-14
| | | | | | | | | | | | | | | | I recently tried to construct a totally generic transport class and found there were certain features missing from the current abstract transport class. Most notable is that you have to hang the data on the class_device but most of the API is framed in terms of the generic device, not the class_device. These changes are two fold - Provide the class_device to all of the setup and configure APIs - Provide and extra API to take the device and the attribute class and return the corresponding class_device Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] add ability to deny binding to SPI transport classJames Bottomley2005-08-14
| | | | | | | | | This patch is necessary if we begin exposing underlying physical disks (which can attach to the SPI transport class) of the hardware RAID cards, since we don't want any SPI parameters binding to the RAID devices. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] add missing hold_mcs parameter to the spi transport classJames Bottomley2005-08-03
| | | | | | | | | | | | | | | | | This parameter is important only to people who take the time to tune the margin control settings, otherwise it's completely irrelevant. However, just in case anyone should want to do this, it's appropriate to include the parameter. I don't do anything with it in DV by design, so the parameter will come up as off by default, so if anyone actually wants to play with the margin control settings they'll have to enable it under the spi_transport class first. I also updated the transfer settings display to report all of the PPR settings instead of only DT, IU and QAS Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] SPI transport class, don't negotiate options not supportedJames Bottomley2005-07-11
| | | | | | | | | At the moment, the transport class blindly tries to set things like QAS and IU, even if the drive won't support them. It's best not to annoy the devices like this and instead only set what the drive says is actually supported. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* [SCSI] update spi transport class so that u320 Domain Validation worksJames Bottomley2005-06-03
| | | | | | | | | | | | | There are several extra things that have to be considered when running Domain Validation on a u320 target (notably how you fall back). Hopefully this should help us when someone adds this transport class to aic79xx. I've tested this on the lsi1030, so I know it works correctly up to u320. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] implement parameter limits in the SPI transport classJames Bottomley2005-05-20
| | | | | | | | | | | | | | There's a basic need not to have parameters go under or over certain values when doing domain validation. The basic ones are max_offset, max_width and min_period This patch makes the transport class take and enforce these three limits. Currently they can be set by the user, although they could obviously be read from the HBA's on-board NVRAM area during slave_configure (if it has one).

* [SCSI] fix command retries in spi_transport classJames Bottomley2005-05-05
| | | | | | | | | | | The premise is that domain validation is likely to trigger errors which it wants to know about, so the only time it should be retrying them is when it gets a unit attention (likely as the result of a previous bus or device reset). Ironically, the previous coding retried three times in all cases except those of unit attention. The attached fixes this to do the right thing.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
