2013-01-03Drivers: ata: remove __dev* attributes.Greg Kroah-Hartman25-94/+85
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

As noted earlier, I don't have much interest in this driver. I agree that there are some other issues with the driver; I think it leaks memory if it is ever allowed to unload, for one.

2012-12-03ahci_platform: perform platform exit in host_stop() hookBrian Norris1-7/+23
AHCI platform devices may provide an exit() routine, via ahci_platform_data, that powers off the SATA core. Such a routine should be executed from the ata_port_operations host_stop() hook. That way, the ATA subsystem can perform any last-minute hardware cleanup (via devres, for example), then trigger the power-off at the appropriate time. This patch fixes bus errors triggered during module removal or device unbinding, seen on an SoC SATA core.

platform_driver_probe() should be used for registering this driver only if we want to "...remove its run-once probe() infrastructure from memory after the driver has bound to the device." However, we may want to leave the probe infrastructure in place in order to support binding/unbinding a device dynamically. This is useful, for instance, as a power management mechanism, where a device can be totally powered down when unbound (whereas with runtime power management, powering down the SATA core would incur unacceptable loss of functionality). Thus, convert this driver to use platform_driver_register(). Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2012-12-03libata: restore acpi disable functionalityAaron Lu1-0/+4
Commit 66fa7f215 "libata-acpi: improve ACPI disabling" introdcued the behaviour of disabling ATA ACPI if ata_acpi_on_devcfg failed the 2nd time, but commit 30dcf76ac dropped this behaviour and this caused problem for Dimitris Damigos, where his laptop can not resume correctly. The bugzilla page for it is: https://bugzilla.kernel.org/show_bug.cgi?id=49331 The problem is, ata_dev_push_id will fail the 2nd time it is invoked, and due to disabling ACPI code is dropped, ata_acpi_on_devcfg which calls ata_dev_push_id will keep failing and eventually made the device disabled. This patch restores the original behaviour, if acpi failed the 2nd time, disable acpi functionality for the device(and we do not event need to add a debug message for this as it is still there ;-).

I am working on a device which uses the cs5536 pata driver. There are some broken hardware revisions out in the field, which can be detected via DMI. On older versions with an embedded BIOS I used libata.dma=0 to disable dma completely. Now we are switching to a coreboot/seabios based BIOS where we have DMI support and so I think its a good idea to get rid of all those hacky kernel parameters as the same image is used other devices where libata.dma=0 is not a good idea.

2012-11-28ata_piix: reenable MS Virtual PC guestsOlaf Hering1-3/+22
An earlier commit cd006086fa5d91414d8ff9ff2b78fbb593878e3c ("ata_piix: defer disks to the Hyper-V drivers by default") broke MS Virtual PC guests. Hyper-V guests and Virtual PC guests have nearly identical DMI info. As a result the driver does currently ignore the emulated hardware in Virtual PC guests and defers the handling to hv_blkvsc. Since Virtual PC does not offer paravirtualized drivers no disks will be found in the guest. One difference in the DMI info is the product version. This patch adds a match for MS Virtual PC 2007 and "unignores" the emulated hardware. This was reported for openSuSE 12.1 in bugzilla: https://bugzilla.novell.com/show_bug.cgi?id=737532 Here is a detailed list of DMI info from example guests: hwinfo --bios: virtual pc guest: System Info: #1 Manufacturer: "Microsoft Corporation" Product: "Virtual Machine" Version: "VS2005R2" Serial: "3178-9905-1533-4840-9282-0569-59" UUID: undefined, but settable Wake-up: 0x06 (Power Switch) Board Info: #2 Manufacturer: "Microsoft Corporation" Product: "Virtual Machine" Version: "5.0" Serial: "3178-9905-1533-4840-9282-0569-59" Chassis Info: #3 Manufacturer: "Microsoft Corporation" Version: "5.0" Serial: "3178-9905-1533-4840-9282-0569-59" Asset Tag: "7188-3705-6309-9738-9645-0364-00" Type: 0x03 (Desktop) Bootup State: 0x03 (Safe) Power Supply State: 0x03 (Safe) Thermal State: 0x01 (Other) Security Status: 0x01 (Other) win2k8 guest: System Info: #1 Manufacturer: "Microsoft Corporation" Product: "Virtual Machine" Version: "7.0" Serial: "9106-3420-9819-5495-1514-2075-48" UUID: undefined, but settable Wake-up: 0x06 (Power Switch) Board Info: #2 Manufacturer: "Microsoft Corporation" Product: "Virtual Machine" Version: "7.0" Serial: "9106-3420-9819-5495-1514-2075-48" Chassis Info: #3 Manufacturer: "Microsoft Corporation" Version: "7.0" Serial: "9106-3420-9819-5495-1514-2075-48" Asset Tag: "7076-9522-6699-1042-9501-1785-77" Type: 0x03 (Desktop) Bootup State: 0x03 (Safe) Power Supply State: 0x03 (Safe) Thermal State: 0x01 (Other) Security Status: 0x01 (Other) win2k12 guest: System Info: #1 Manufacturer: "Microsoft Corporation" Product: "Virtual Machine" Version: "7.0" Serial: "8179-1954-0187-0085-3868-2270-14" UUID: undefined, but settable Wake-up: 0x06 (Power Switch) Board Info: #2 Manufacturer: "Microsoft Corporation" Product: "Virtual Machine" Version: "7.0" Serial: "8179-1954-0187-0085-3868-2270-14" Chassis Info: #3 Manufacturer: "Microsoft Corporation" Version: "7.0" Serial: "8179-1954-0187-0085-3868-2270-14" Asset Tag: "8374-0485-4557-6331-0620-5845-25" Type: 0x03 (Desktop) Bootup State: 0x03 (Safe) Power Supply State: 0x03 (Safe) Thermal State: 0x01 (Other) Security Status: 0x01 (Other) Signed-off-by: Olaf Hering <olaf@aepfle.de> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2012-11-28sata_promise: fix hardreset lockdep errorMikael Pettersson1-2/+13
sata_promise's pdc_hard_reset_port() needs to serialize because it flips a port-specific bit in controller register that's shared by all ports. The code takes the ata host lock for this, but that's broken because an interrupt may arrive on our irq during the hard reset sequence, and that too will take the ata host lock. With lockdep enabled a big nasty warning is seen. Fixed by adding private state to the ata host structure, containing a second lock used only for serializing the hard reset sequences. This eliminated the lockdep warnings both on my test rig and on the original reporter's machine.

Pull SCSI fixes from James Bottomley: "This is a set of four bug fixes. The isci one is an obvious thinko (using request buffer instead of response buffer) which causes a command to fail. The three others are DIF/DIX updates which are required because they're part of a series of ten patches, the other seven of which went into the block layer during the merge window meaning our current DIF/DIX implementation is broken without these three.

2012-11-15sata_highbank: mark ahci_highbank_probe as __devinitArnd Bergmann1-1/+1
The ahci_highbank_probe function is incorrectly marked as __init, which means it can get discarded at boot time, which might be a problem if for some reason the device only becomes operational after loading another module. Using __devinit instead avoids seeing this warning for every build: WARNING: vmlinux.o(.data+0xf7b0): Section mismatch in reference from the variable ahci_highbank_driver to the function .init.text:ahci_highbank_probe() The variable ahci_highbank_driver references the function __init ahci_highbank_probe() If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Mark Langsdorf <mark.langsdorf@calxeda.com> Cc: Rob Herring <rob.herring@calxeda.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

commit 6b66d95895c149cbc04d4fac5a2f5477c543a8ae didn't handle SATA PMP case in ata_acpi_bind_device and will cause a NULL ptr dereference when user attached a SATA drive to the PMP port. Fix this by checking PMP support.
