* [libata scsi] improve scsi error handling with ata_scsi_set_sense()Douglas Gilbert2005-10-09
| | | | | | | | | | | | | | - change "xlat" and "fill" actors in libata-scsi so they are responsible for SCSI status and sense data when they return 1. This allows GOOD status or a specialized error to be set. - yield an error for mode sense requests for saved values [sat-r06] - remove static inlines for ata_bad_scsiop() and ata_bad_cdb() which are no longer used Signed-off-by: Douglas Gilbert <dougg@torque.net> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

| | * [SCSI] Legacy MegaRAID: Fix READ CAPACITYJames Bottomley2005-10-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Legacy megaraid cards can't actually cope with the scatter/gather version of the READ CAPACITY command (which is what we now send them since altering all SCSI internal I/O to go via the block layer). Fix this (and a few other broken megaraid driver assumptions) by sending the non-sg version of the command if the sg list only has a single element.

| | * [SCSI] aic7xxx/aic79xx: fix module removal path not to panicJames Bottomley2005-10-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In these drivers, scsi_remove_host() is called too late, at the point it is called, the driver has already shut down too far to accept any I/O that the shutdown might generate. Any generated I/O actually triggers a panic. Fix this by calling scsi_remove_host() as early as possible and not calling scsi_host_put() until just before we kfree the ahc_softc.

| | * [SCSI] fix potential panic with proc on module removalJames Bottomley2005-10-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a problem in our host release in that it calls scsi_proc_hostdir_rm(). However, if you hold a reference to the host as you remove the module, the host template (which proc uses) will be freed and the system will panic when the host device is finally released. Fix this by moving scsi_proc_hostdir_rm() to where it should be: in scsi_remove_host(). Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
| | * [SCSI] aacraid: remove aac_insert_entryMark Haverkamp2005-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Received from Mark Salyzyn from Adaptec. High Priority Queues have *never* been used in the entire history of the aac based adapters. Associated with this, aac_insert_entry can be removed, SavedIrql can be removed & padding variable can be removed. With the movement of SavedIrql out & replaced with an automatic variable qflags, the locking can be refined somewhat. The sparse warnings did not catch the need for byte swapping in the 'dprintk' debugging print macros, so fixed this up when this code was moved outside of the now refined locking.

| | * [SCSI] aacraid: fib size math fixMark Haverkamp2005-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Received from Mark Salyzyn from Adaptec. The size of the command packet's scatter gather list maximum size was miscalculated in the low range leading to the driver initialization limiting the maximum i/o size that could go to the Adapter. There were no negative operational side effects resulting from this bad math, only a subtle limit in performance of the Adapter at the top end of the range.

| | * [SCSI] aacraid: initialization timeoutMark Haverkamp2005-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Received from Mark Salyzyn from Adaptec. In the rare instances where the adapter, or the motherboard, is misbehaving; driver initialization or shutdown becomes problematic. By introducing a 3 minute timeout on the first interrupt driven command during initialization, or the issuance of the adapter shutdown command during driver unload, we can resolve the lockup problems induced by common (but rare) hardware misbehaviors. The timeout during initialization, should it occur, is accompanied by a message presented to the console and the logs indicating that the user should inspect and resolve problems with interrupt routing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Received from Mark Salyzyn from Adaptec.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Received from Mark Salyzyn from Adaptec. There are a few adapters that are capable of creating devices with this large of a capacity, but now that we have the large fib support in, the management applications will be capable of generating them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since our max_lun is unconditionally set to 1, we might as well hardcode a LUN 0 probe, rather than a wildcard LUN scan. The ide-scsi driver sets max_lun to a value greater than under certain conditions: if ((drive->id->last_lun & 0x7) != 7) host->max_lun = (drive->id->last_lun & 0x7) + 1; else host->max_lun = 1; last_lun is Word 126 of IDENTIFY PACKET DEVICE, marked as obsolete and undocumented in non-ancient specs. We'll leave it out for now. Should the need arise to support multi-LUN ATAPI devices, we'll probably want to add the above code. Finally, there have been reports of REPORT LUNS commands locking up ATAPI drives. Eliminating the wildcard LUN scan could help reduce the trouble from problematic drives.
| * | | [libata] improve device scanJeff Garzik2005-10-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace SCSI's legacy "bang at the door" method of probing with one directly controlled by the underlying ATA transport layer. We now only call scsi_scan_target() for devices we find, rather than probing every possible channel/id within a certain range.

* | | | libata: bitmask based pci init functions for one or two portsAlan Cox2005-10-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This redoes the n_ports logic I proposed before as a bitmask. ata_pci_init_native_mode is now used with a mask allowing for mixed mode stuff later on. ata_pci_init_legacy_port is called with port number and does one port now not two. Instead it is called twice by the ata init logic which cleans both of them up. There are stil limits in the original code left over - IRQ/port mapping for legacy mode should be arch specific values - You can have one legacy mode IDE adapter per PCI root bridge on some systems - Doesn't handle mixed mode devices yet (but is now a lot closer to it)
* | | | [PATCH] libata: Marvell SATA support (DMA mode) (resend: v0.22)Brett Russ2005-10-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is my libata compatible low level driver for the Marvell SATA family. Currently it runs in DMA mode on a 6081 chip. The 5xxx series parts are not yet DMA capable in this driver because the registers have differences that haven't been accounted for yet. Basically, I'm focused on the 6xxx series right now. I apologize for those seeing problems on the 5xxx series, I've not had a chance to look at those problems yet. For those curious, the previous bug causing the SCSI timeout and subsequent panics was caused by an improper clear of hc_irq_cause in mv_host_intr(). This version is running well in my environment (6081 chips, with/without SW raid1) and is showing equal or better performance compared to the Marvell driver (mv_sata) in my initial tests (timed dd's of reads/writes to/from memory/disk). I still need to look at the causes of occasional problems such as this: ata11: translating stat 0x35 err 0x00 to sense ata11: status=0x35 { DeviceFault SeekComplete CorrectedError Error } SCSI error : <10 0 0 0> return code = 0x8000002 Current sda: sense key Hardware Error end_request: I/O error, dev sda, sector 3155010 and this, seen at init time: ATA: abnormal status 0x80 on port 0xE093911C but they aren't showstoppers.
