* USB: OHCI: avoid conflicting platform driversArnd Bergmann2013-04-251-18/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | Like the EHCI driver, OHCI supports a large number of different platform glue drivers by directly including them, which causes problems with conflicting macro definitions in some cases. As more ARM architecture specific back-ends are required to coexist in a single build, we should split those out into separate drivers. Unfortunately, the infrastructure for that is still under development, so to give us more time, this uses a separate *_PLATFORM_DRIVER macro for each ARM specific OHCI backend, just like we already do on PowerPC and some of the other ARM platforms. In linux-3.10, only the SPEAr and CNS3xxx back-ends would actually conflict without this patch, but over time we would get more of them, so this is a way to avoid having to patch the driver every time it breaks. We should still split out all back-ends into separate loadable modules, but that work is only needed to improve code size and cleanliness after this patch, not for correctness. While we're here, this fixes the incorrectly sorted error path for the OMAP1 and OMAP3 backends to ensure we always unregister the exact set of drivers that were registered before erroring out.

| | | | | | | | | | | | | | Merge ohci_finish_controller_resume with ohci_resume as suggested by Alan Stern. Since ohci_finish_controller_resume no longer exists, update the various OHCI drivers to call ohci_resume() instead. Some drivers used to set themselves the bit HCD_FLAG_HW_ACCESSIBLE, which is now handled by ohci_resume().

| | | | | | | | | | | This patch (as1614) updates the isochronous scheduling in ohci-hcd to match the new semantics for URB_ISO_ASAP. Testing revealed a hardware bug in the way my OHCI controller handles expired isochronous TDs; consequently the patch tries hard to avoid creating them (unlike the ehci-hcd and uhci-hcd drivers).

A lot of activities this round including considerable API and behavior cleanups. * delayed_work combines a timer and a work item. The handling of the timer part has always been a bit clunky leading to confusing cancelation API with weird corner-case behaviors. delayed_work is updated to use new IRQ safe timer and cancelation now works as expected. * Another deficiency of delayed_work was lack of the counterpart of mod_timer() which led to cancel+queue combinations or open-coded timer+work usages. mod_delayed_work[_on]() are added. These two delayed_work changes make delayed_work provide interface and behave like timer which is executed with process context. * A work item could be executed concurrently on multiple CPUs, which is rather unintuitive and made flush_work() behavior confusing and half-broken under certain circumstances. This problem doesn't exist for non-reentrant workqueues. While non-reentrancy check isn't free, the overhead is incurred only when a work item bounces across different CPUs and even in simulated pathological scenario the overhead isn't too high. All workqueues are made non-reentrant. This removes the distinction between flush_[delayed_]work() and flush_[delayed_]_work_sync(). The former is now as strong as the latter and the specified work item is guaranteed to have finished execution of any previous queueing on return. * In addition to the various bug fixes, Lai redid and simplified CPU hotplug handling significantly. * Joonsoo introduced system_highpri_wq and used it during CPU hotplug. There are two merge commits - one to pull in IRQ safe timer from tip/timers/core and the other to pull in CPU hotplug fixes from wq/for-3.6-fixes as Lai's hotplug restructuring depended on them." Fixed a number of trivial conflicts, but the more interesting conflicts were silent ones where the deprecated interfaces had been used by new code in the merge window, and thus didn't cause any real data conflicts. Tejun pointed out a few of them, I fixed a couple more. * 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: (46 commits) workqueue: remove spurious WARN_ON_ONCE(in_irq()) from try_to_grab_pending() workqueue: use cwq_set_max_active() helper for workqueue_set_max_active() workqueue: introduce cwq_set_max_active() helper for thaw_workqueues() workqueue: remove @delayed from cwq_dec_nr_in_flight() workqueue: fix possible stall on try_to_grab_pending() of a delayed work item workqueue: use hotcpu_notifier() for workqueue_cpu_down_callback() workqueue: use __cpuinit instead of __devinit for cpu callbacks workqueue: rename manager_mutex to assoc_mutex workqueue: WORKER_REBIND is no longer necessary for idle rebinding workqueue: WORKER_REBIND is no longer necessary for busy rebinding workqueue: reimplement idle worker rebinding workqueue: deprecate __cancel_delayed_work() workqueue: reimplement cancel_delayed_work() using try_to_grab_pending() workqueue: use mod_delayed_work() instead of __cancel + queue workqueue: use irqsafe timer for delayed_work workqueue: clean up delayed_work initializers and add missing one workqueue: make deferrable delayed_work initializer names consistent workqueue: cosmetic whitespace updates for macro definitions workqueue: deprecate system_nrt[_freezable]_wq workqueue: deprecate flush[_delayed]_work_sync() ...

Mark them deprecated and convert all users to flush[_delayed]_work(). If you're cc'd and wondering what's going on: Now all workqueues are non-reentrant and the regular flushes guarantee that the work item is not pending or running on any CPU on return, so there's no reason to use the sync flushes at all and they're going away.

I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis." Fixed up some conflicts from other header file cleanups and moving code around that has happened in the meantime, so David's testing is somewhat weakened by that.

| * OHCI: final fix for NVIDIA problems (I hope)Alan Stern2011-11-181-9/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problems with NVIDIA's OHCI host controllers persist. After looking carefully through the spec, I finally realized that when a controller is reset it then automatically goes into a SUSPEND state in which it is completely quiescent (no DMA and no IRQs) and from which it will not awaken until the system puts it into the OPERATIONAL state. Therefore there's no need to worry about controllers being in the RESET state for extended periods, or remaining in the OPERATIONAL state during system shutdown. The proper action for device initialization is to put the controller into the RESET state (if it's not there already) and then to issue a software reset. Similarly, the proper action for device shutdown is simply to do a software reset. This patch (as1499) implements such an approach. It simplifies initialization and shutdown, and allows the NVIDIA shutdown-quirk code to be removed.

* USB: remove remaining usages of hcd->state from usbcore and fix regressionAlan Stern2011-05-191-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1467) removes the last usages of hcd->state from usbcore. We no longer check to see if an interrupt handler finds that a controller has died; instead we rely on host controller drivers to make an explicit call to usb_hc_died(). This fixes a regression introduced by commit 9b37596a2e860404503a3f2a6513db60c296bfdc (USB: move usbcore away from hcd->state). It used to be that when a controller shared an IRQ with another device and an interrupt arrived while hcd->state was set to HC_STATE_HALT, the interrupt handler would be skipped. The commit removed that test; as a result the current code doesn't skip calling the handler and ends up believing the controller has died, even though it's only temporarily stopped. The solution is to ignore HC_STATE_HALT following the handler's return. As a consequence of this change, several of the host controller drivers need to be modified. They can no longer implicitly rely on usbcore realizing that a controller has died because of hcd->state. The patch adds calls to usb_hc_died() in the appropriate places. The patch also changes a few of the interrupt handlers. They don't expect to be called when hcd->state is equal to HC_STATE_HALT, even if the controller is still alive. Early returns were added to avoid any confusion.

* | USB host: Move AMD PLL quirk to pci-quirks.cAndiry Xu2011-03-011-11/+2

AMD PLL quirk disable the optional PM feature inside specific SB700/SB800/Hudson-2/3 platforms under the following conditions: 1. If an isochronous device is connected to OHCI/EHCI/xHCI port and is active; 2. Optional PM feature that powers down the internal Bus PLL when the link is in low power state is enabled. Without AMD PLL quirk, USB isochronous stream may stutter or have breaks occasionally, which greatly impair the performance of audio/video streams. Currently AMD PLL quirk is implemented in OHCI and EHCI driver, and will be added to xHCI driver too. They are doing similar things actually, so move the quirk code to pci-quirks.c, which has several advantages: 1. Remove duplicate defines and functions in OHCI/EHCI (and xHCI) driver and make them cleaner; 2. AMD chipset information will be probed only once and then stored. Currently they're probed during every OHCI/EHCI initialization, move the detect code to pci-quirks.c saves the repeat detect cost; 3. Build up synchronization among OHCI/EHCI/xHCI driver. In current code, every host controller enable/disable PLL only according to its own status, and may enable PLL while there is still isoc transfer on other HCs. Move the quirk to pci-quirks.c prevents this issue.
