2008-08-22libata: Fix a large collection of DMA mode mismatchesAlan Cox6-11/+11
Dave Müller sent a diff for the pata_oldpiix that highlighted a problem where a lot of the ATA drivers assume dma_mode == 0 means "no DMA" while the core code uses 0xFF. This turns out to have other consequences such as code doing >= XFER_UDMA_0 also catching 0xFF as UDMAlots. Fortunately it doesn't generally affect set_dma_mode, although some drivers call back into their own set mode code from other points. Having been through the drivers I've added helpers for using_udma/using_mwdma dma_enabled so that people don't open code ranges that may change (eg if UDMA8 appears somewhere) Thanks to David for the initial bits [and added fix for pata_oldpiix from and signed-off-by Dave Mueller <dave.mueller@gmx.ch> -jg] Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-08-22ahci: sis controllers actually can do PMPTejun Heo1-3/+3
SIS controllers were blacklisted for PMP as enabling it made device detection fail whether the device was PMP or not - the natural conclusion was the controller chokes on SRST w/ pmp==15. However, it turned out that the controller just didn't like issuing SRST after hardreset w/o clearing SError first. Interestingly, the SRST itself succeeds but the following commands fail. If SError is cleared between hardreset and SRST, which is the default behavior now, everything works fine and SIS controllers work with PMPs happily. Remove PMP blacklisting for SIS AHCIs.

2008-08-22libata: restore SControl on detachTejun Heo1-5/+5
Save SControl during probing and restore it on detach. This prevents adjustments made by libata drivers to seep into the next driver which gets attached (be it a libata one or not). It's not clear whether SControl also needs to be restored on suspend. The next system to have control (ACPI or kexec'd kernel) would probably like to see the original SControl value but there's no guarantee that a link is gonna keep working after SControl is adjusted without a reset and adding a reset and modified recovery cycle soley for this is an overkill. For now, do it only for detach. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-08-22libata: always do follow-up SRST if hardreset returned -EAGAINTejun Heo1-14/+6
As an optimization, follow-up SRST used to be skipped if classification wasn't requested even when hardreset requested it via -EAGAIN. However, some hardresets can't wait for device readiness and skipping SRST can cause timeout or other failures during revalidation. Always perform follow-up SRST if hardreset returns -EAGAIN. This makes reset paths more predictable and thus less error-prone. While at it, move hardreset error checking such that it's done right after hardreset is finished. This simplifies followup SRST condition check a bit and makes the reset path easier to modify. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

Current storage servers ignore the obsolete bytes, but older models fail to execute the command and report an incorrect length error. This causes the device initilization for these devices to fail.

2008-08-21USB: automatically enable RHSC interruptsAlan Stern22-72/+31
This patch (as1069c) changes the way OHCI root-hub status-change interrupts are enabled. Currently a special HCD method, hub_irq_enable(), is called when the hub driver is finished using a root hub. This approach turns out to be subject to races, resulting in unnecessary polling. The patch does away with the method entirely. Instead, the driver automatically enables the RHSC interrupt when no more status changes are present. This scheme is safe with controllers using level-triggered semantics for their interrupt flags.

2008-08-21USB: Don't rebind before "complete" callbackAlan Stern1-21/+9
This patch (as1130) fixes an incompatibility between the new PM infrastructure and USB power management. We are not allowed to call drivers' probe routines during a system sleep transition between the "prepare" and "complete" callbacks, but that's exactly what we do when a driver doesn't have full suspend/resume support. Such drivers are unbound during the "suspend" call and reprobed during the "resume" call. The patch causes the reprobe step to be skipped if the "complete" callback hasn't been issued yet, i.e., if the interface's dev.power.status field is not equal to DPM_ON. Thus during the "resume" callback nothing bad will happen, and during the final "complete" callback the reprobing will occur as desired. This fixes the problem reported in Bugzilla #11263.

2008-08-21USB: Add new PM callback methods for USBAlan Stern3-19/+72
This patch (as1129) adds support for the new PM callbacks to usbcore. The new callbacks merely invoke the same old USB power management routines as the old ones did. A minor improvement is that the callbacks are present only in the "USB-device" device_type structure, rather than in the bus_type structure. This way they will be invoked only for USB devices, not for USB interfaces. The core USB PM routines automatically handle suspending and resuming interfaces along with their devices.

2008-08-21USB: Defer Set-Interface for suspended devicesAlan Stern1-3/+28
This patch (as1128) fixes one of the problems related to the new PM infrastructure. We are not allowed to register new child devices during the middle of a system sleep transition, but unbinding a USB driver causes the core to automatically install altsetting 0 and thereby create new endpoint pseudo-devices. The patch fixes this problem (and the related problem that installing altsetting 0 will fail if the device is suspended) by deferring the Set-Interface call until some later time when it is legal and can succeed. Possible later times are: when a new driver is being probed for the interface, and when the interface is being resumed.

2008-08-21UIO: generic irq handling for some uio platform devicesMagnus Damm3-0/+202
This is V3 of uio_pdrv_genirq.c, a platform driver for UIO with generic IRQ handling code. This driver is very similar to the regular UIO platform driver, but is only suitable for devices that are connected to the interrupt controller using unique interrupt lines. The uio_pdrv_genirq driver includes generic interrupt handling code which disables the serviced interrupt in the interrupt controller and makes the user space driver responsible for acknowledging the interrupt in the device and reenabling the interrupt in the interrupt controller. Shared interrupts are not supported since the in-kernel interrupt handler will disable the interrupt line in the interrupt controller, and in a shared interrupt configuration this will stop other devices from delivering interrupts.

2008-08-21PM: don't skip device PM init when CONFIG_PM_SLEEP isn't set and CONFIG_PM ↵Alan Stern3-15/+16
is set This patch (as1124) fixes a couple of bugs in the PM core. The new dev->power.status field should be initialized regardless of whether CONFIG_PM_SLEEP is enabled, and similarly dpm_sysfs_add() should be called whenever CONFIG_PM is enabled. The patch separates out the call to dpm_sysfs_add() from the call to device_pm_add(). As a result device_pm_add() can no longer return an error, so its return type is changed to void.

2008-08-21driver model: anti-oopsing medicineDavid Brownell1-0/+11
Anti-oops medicine for the class iterators ... the oops was observed when a class was implicitly referenced before it was initialized.

2008-08-21dev_printk(): constify the `dev' argumentJean Delvare1-1/+1
Add const markings to dev_name and dev_driver_string to make it clear that dev_printk doesn't modify dev. This is a prerequisite to adding more const markings to other functions make it clearer, which functions can modify dev and which can't.

2008-08-20fbdefio: add set_page_dirty handler to deferred IO FBIan Campbell2-0/+23
Fixes kernel BUG at lib/radix-tree.c:473. Previously the handler was incidentally provided by tmpfs but this was removed with: commit 14fcc23fdc78e9d32372553ccf21758a9bd56fa1 Author: Hugh Dickins <hugh@veritas.com> Date: Mon Jul 28 15:46:19 2008 -0700 tmpfs: fix kernel BUG in shmem_delete_inode relying on this behaviour was incorrect in any case and the BUG also appeared when the device node was on an ext3 filesystem. v2: override a_ops at open() time rather than mmap() time to minimise races per AKPM's concerns.
