2005-09-08[PATCH] scan all enabled ports on ata_piixHannes Reinecke
ICH6 spec defines the PORT_ bits as: PORT_ENABLED (R/W): 0 = Disabled. The port is in the off state and cannot detect any devices. 1 = Enabled. The port can transition between the on, partial, and slumber states and can detect devices. PORT_PRESENT (R/O) The status of this bit may change at any time. This bit is cleared when the port is disabled via PORT_ENABLED. This bit is not cleared upon surprise removal of a device. So from a textual view it is not necessary that PORT_PRESENT _must_ be set, especially if a device detection has to be done anyway. And, in fact, this is the view that ACER has been taken with its new Laptops (e.g. Travelmate 4150). And the definition of PORT_ENABLED / PORT_PRESENT is mixed up, btw.

2005-09-07[PATCH] sata_sis: Add support for SiS182 chipsetArnaud Patard
This patch adds support for the SiS182 sata chipset. This is a minimalistic version of the patch from http://bugme.osdl.org/show_bug.cgi?id=4192. Basically, it add the PCI IDs and handles the change of the 2nd port adress register. Signed-Off-By: Arnaud Patard <apatard@mandriva.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2005-09-07[PATCH] libata: fix pio_mask values (take 2)Brett Russ
ata_get_mode_mask() uses bits 3 and 4 in the pio_mask to represent PIO modes 3 and 4. The value read from the drive, which reports support for PIO3 and PIO4 in bits 0 and 1, is shifted left by 3 bits and OR'd with 0x7 (which then corresponds to PIO 2-0 in libata). Thus, the drivers below need adjustments to comply with the way pio_mask is used. I changed the masks from the commented values to all support PIO4-0, since the spec mandates that PIO0-2 are supported and there's no reason not to support PIO3 IMO.

2005-09-06[SCSI] quieten messages on scsi_execute commandsJames Bottomley
scsi_io_completion() can be a bit noisy about certain conditions. Previously this wasn't a problem for internally generated commands, since they never hit it. However, since we do all SCSI commands via bios, now they do. user CD testers like magicdev are now getting not ready messages every time they touch the CD to see if there's anything in it. Fix this by making all scsi_execute commands REQ_QUIET and making scsi_finish_io() not say anything for REQ_QUIET. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2005-09-06[SCSI] sd: pause in sd_spinup_disk for slow USB devicesAlan Stern
This patch adds a delay tailored for USB flash devices that are slow to initialize their firmware. The symptom is a repeated Unit Attention with ASC=0x28 (Not Ready to Ready transition). The patch will wait for up to 5 seconds for such devices to become ready. Normal devices won't send the repeated Unit Attention sense key and hence won't trigger the patch. This fixes a problem with James Roberts-Thomson's USB device, and I've seen several reports of other devices exhibiting the same symptoms -- presumably they will be helped as well.

2005-09-06[SCSI] return success after retries in scsi_eh_turAlan Stern
The problem lies in the way the error handler uses TEST UNIT READY to tell whether error recovery has succeeded. The scsi_eh_tur function gives up after one round of retrying; after that it decides that more error recovery is needed. However TUR is liable to report sense data indicating a retry is needed when in fact error recovery has succeeded. A typical example might be SK=2, ASC=4, ASCQ=1 (Logical unit in process of becoming ready). The mere fact that we were able to get a sensible reply to the TUR should indicate that the device is working well enough to stop error recovery. I ran across a case back in January where this happened. A CD-ROM drive timed out the INQUIRY command, and a device reset fixed the blockage. But then the drive kept responding with 2/4/1 -- because it was spinning up I suppose -- until the error handler gave up and placed it offline. If the initial INQUIRY had received the 2/4/1 instead, everything would have worked okay. It doesn't seem reasonable for things to fail just because the error handler had started running.

2005-08-30[SCSI] embryonic RAID classJames Bottomley
The idea behind a RAID class is to provide a uniform interface to all RAID subsystems (both hardware and software) in the kernel. To do that, I've made this class a transport class that's entirely subsystem independent (although the matching routines have to match per subsystem, as you'll see looking at the code). I put it in the scsi subdirectory purely because I needed somewhere to play with it, but it's not a scsi specific module. I used a fusion raid card as the test bed for this; with that kind of card, this is the type of class output you get: jejb@titanic> ls -l /sys/class/raid_devices/20\:0\:0\:0/ total 0 lrwxrwxrwx 1 root root 0 Aug 16 17:21 component-0 -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:1:0/20:1:0:0/ lrwxrwxrwx 1 root root 0 Aug 16 17:21 component-1 -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:1:1/20:1:1:0/ lrwxrwxrwx 1 root root 0 Aug 16 17:21 device -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:0:0/20:0:0:0/ -r--r--r-- 1 root root 16384 Aug 16 17:21 level -r--r--r-- 1 root root 16384 Aug 16 17:21 resync -r--r--r-- 1 root root 16384 Aug 16 17:21 state So it's really simple: for a SCSI device representing a hardware raid, it shows the raid level, the array state, the resync % complete (if the state is resyncing) and the underlying components of the RAID (these are exposed in fusion on the virtual channel 1). As you can see, this type of information can be exported by almost anything, including software raid. The more difficult trick, of course, is going to be getting it to perform configuration type actions with writable attributes. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
