* [SCSI] remove target parent limitiationChristoph Hellwig2006-01-146-48/+49
| | | | | | | | | | | | | | | | | | | | | | | | | When James Smart fixed the issue of the userspace scan atributes crashing the system with the FC transport class he added a patch to let the transport class check if the parent is valid for a given transport class. When adding support for the integrated raid of fusion sas devices we ran into a problem with that, as it didn't allow adding virtual raid volumes without the transport class knowing about it. So this patch adds a user_scan attribute instead, that takes over from scsi_scan_host_selected if the transport class sets it and thus lets the transport class control the user-initiated scanning. As this plugs the hole about user-initiated scanning the target_parent hook goes away and we rely on callers of the scanning routines to do something sensible. For SAS this meant I had to switch from a spinlock to a mutex to synchronize the topology linked lists, in FC they were completely unsynchronized which seems wrong.

* [SCSI] I2O: move pci_request_regions() just behind pci_enable_device()Salyzyn, Mark2006-01-141-4/+6
| | | | | | | | | | | | | | | | | | | | | | The problem in dpt_i2o could be the pci config space accesses it triggers as it loads, dangerous to do if there is any I/O activity going on in the other driver (probable if a boot driver I guess). I approve this patch to dpt_i2o.c, and am applying it to the Adaptec branch of the driver. Thanks for the investigation Ryoji. --- In linux 2.6.15, data transfer does hang when both dpt_i2o and i2o_block drivers are loaded. It seems that location of pci_request_regions() are wrong. I moved it just behind pci_enable_device() like other drivers, and it becomes fine. Signed-off-by: Ryoji Kamei <kamei@miraclelinux.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* [SCSI] always handle REQ_BLOCK_PC requests in common codeChristoph Hellwig2006-01-144-91/+13
| | | | | | | | | | | | | | LLDDs should never see REQ_BLOCK_PC requests, we can handle them just fine in the core code. There is a small behaviour change in that some check in sr's rw_intr are bypassed, but I consider the old behaviour a bug. Mike found this cleanup opportunity and provdided early patches, so all the credit goes to him, even if I redid the patches from scratch beause that was easier than forward-porting the old patches.

This fixes the oops Eric Moore saw when removing and reloading mptsas. Also don't try the scsi_remove_target call unless operating on an end device.

* [SCSI] Pass proper device from BusLogic to SCSI layerPetr Vandrovec2006-01-121-1/+2
| | | | | | | | | | | | | | | | | | | | | | While trying to get SUSE's SLES9 working on system with more than 4GB we've noticed that SCSI layer happilly passes addresses over 4GB to the buslogic driver, which is quite a big problem as buslogic can generate only 32bit busmastering cycles. Fortunately in the current kernels this problem does not exist anymore as SCSI layer now assumes 4GB capable device by default, but it is still good idea to pass correct device structure to the SCSI layer. If nothing else, /sys/block/sda/device now points to /sys/devices/pci0000:00/0000:00:10.0/host0/... instead of /sys/devices/platform/host0/... like it did in the past. Change does nothing for ISA based BusLogic adapters, they'll still end under platform (and they are probably broken for long time as I do not see anything forcing ISA 16MB limit for them).

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch works around a problem with spurious interrupts seen at boot time when a MAXTOR 6H500F0 drive is present. An ATA interrupt condition is mysteriously present at start of day. If we took too long in issuing the first command, the kernel would basically get tired of the spurious interrupts and turn the interrupt off. Issuing the first command essentially causes the interrupt condition to get acknowledged. I haven't seen this happen with any other drives. What I basically do is ack ATA status by reading it regardless of whether we're expecting to have to handle an interrupt. This clears the start-of-day anomalous interrupt condition, and keeps the kernel from disabling that interrupt due to too many spurious interrupts. Also, I fixed a bug where hotplug interrupts weren't getting acknowledged as handled in the ISR. This was not the cause of the spurious interrupts, but it's the right thing to do anyway.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | HDIO_GETGEO is implemented in most block drivers, and all of them have to duplicate the code to copy the structure to userspace, as well as getting the start sector. This patch moves that to common code [1] and adds a ->getgeo method to fill out the raw kernel hd_geometry structure. For many drivers this means ->ioctl can go away now. [1] the s390 block drivers are odd in this respect. xpram sets ->start to 4 always which seems more than odd, and the dasd driver shifts the start offset around, probably because of it's non-standard sector size.
