* usbmon: Add class for binary interfacePete Zaitcev2007-07-134-18/+66
| | | | | | | | | | | | | | | | Add a class which allows for an easier integration with udev. This code was originally written by Paolo Abeni, and arrived to my tree as a part of big patch to add binary API on December 18. As I understand, Paolo always meant the class to be a part of the whole thing. This is his udev rule to go along with the patch: KERNEL=="usbmon[0-9]*", NAME="usbmon%n", MODE="0440",OWNER="root",GROUP="bin" Signed-off-by: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* USB: oti6858 usb-serial driver (in Nokia CA-42 cable)Kees Lemmens2007-07-134-0/+1367
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Last week I've been searching for a driver for the CA-42 cable (see usb below) that fitted my kernel 2.6.20. I only found an abandoned version for a driver on your website that indeed worked on 2.6.18 but wouldn't even compile with a more recent 2.6.20 kernel. I fiddled 2 evenings with the kernel code and have patched it up now to work with the modifications in the 2.6.20 kernel. The patch is attached hereafter and it works fine (at least for me :-) ). Bus 2 Device 13: ID 0ea0:6858 Ours Technology, Inc. I had to fiddle a little with the settings in .gnokiirc but that also occurred with the older 2.6.18 kernel. Nevertheless, on one system with this cable and my Nokia 6070 I had best results with : model = 6510 connection = dku5 while on an other system with the same kernel, cable and phone it only worked with : model = AT connection = serial serial_write_usleep = 1 From: Kees Lemmens <C.W.J.Lemmens@ewi.tudelft.nl> Cc: <pawel.kot@gmail.com> Cc: <bozo@andrews.hu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* USB: make hub driver's release more robustAlan Stern2007-07-131-28/+31
| | | | | | | | | | | | This revised patch (as893c) improves the method used by the hub driver to release its private data structure. The current code is non-robust, relying on a memory region not getting reused by another driver after it has been freed. The patch adds a reference count to the structure, resolving the question of when to release it.

| | | | | | | | | | | | This revised patch (as891b) removes two unnecessary references to intf->dev.power.power_state from usb-storage, and replaces a reference to root_hub->dev.power.power_state with a check of hcd->state.

* USB: don't unsuspend for a new connectionAlan Stern2007-07-131-13/+0
| | | | | | | | | | | | This patch (as889) prevents the hub driver from trying to resume a port when there is a new connection. For one thing, the resume is not needed -- the upcoming port reset will clear the suspend feature automatically. For another, on some systems the resume fails and causes problems.

* USB: move bus_suspend and bus_resume method callsAlan Stern2007-07-133-39/+43
| | | | | | | | | | | | | | | | | | | | | | | | | This patch (as885) moves the root-hub bus_suspend() and bus_resume() method calls from the hub driver's suspend and resume methods into the usb_generic driver methods, where they make just as much sense. Their old locations were not fully correct. For example, in a kernel compiled without CONFIG_USB_SUSPEND, if one were to do: echo -n 1-0:1.0 >/sys/bus/usb/drivers/hub/unbind to unbind the hub driver from a root hub, there would then be no way to suspend that root hub. Attempts to put the system to sleep would fail; the USB controller driver would refuse to suspend because the root hub was still active. The patch also makes a very slight change in the way devices with no driver are handled during suspend. Rather than doing a standard USB port-suspend directly, now the suspend routine in usb_generic is called. In practice this should never affect anyone.

* USB: Implement PM FREEZE and PRETHAWAlan Stern2007-07-132-5/+8
| | | | | | | | | | | | | This patch (as884) finally implements the time-saving semantics possible with the Power Management FREEZE and PRETHAW events. Their proper handling requires only that devices be quiesced, with interrupts and DMA turned off; non-root USB devices don't actually need to be put in a suspended state. The patch checks and avoids doing the suspend call when possible. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

R8A66597 is Renesas USB 2.0 host and peripheral combined controller device originally designed for embedded products. As a limitation of this device, it does not support externel hub more than 2 tier, and cannot communicate with a USB device more than 10. Then this device is not compatible with EHCI and/or OHCI, I wrote driver support patch based on sl811 code. This driver has the following unique specifications: - Implement transfer timeout to share one pipe with plural endpoint. - Detach detection of a USB device connected to externel hub.

* USB: EHCI support for big-endian descriptorsStefan Roese2007-07-137-302/+432
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements supports for EHCI controllers whose in-memory data structures are represented in big-endian format. This is needed (unfortunately) for the AMCC PPC440EPx SoC EHCI controller; the EHCI spec doesn't specify little-endian format, although that's what most other implementations use. The guts of the patch are to introduce the hc32 type and change all references from le32 to hc32. All access routines are converted from cpu_to_le32(...) to cpu_to_hc32(ehci, ...) and similar for the other "direction". (This is the same approach used with OHCI.) David fixed: Whitespace fixes; refresh against ehci cpufreq patch; move glue for that PPC driver to the patch adding it; fix free symbol capture bugs in modified "constant" macros; and make "hc32" etc be "le32" unless we really need the BE options, so "sparse" can do some real good.

| | | | | | | | | | | | | | | | | EHCI controllers that don't cache enough microframes can get MMF errors when CPU frequency changes occur between the start and completion of split interrupt transactions, due to delays in reading main memory (caused by CPU cache snoop delays). This patch adds a cpufreq notifier to the EHCI driver that will inactivate split interrupt transactions during frequency transitions. It was tested on Intel ICH7 and Serverworks/Broadcom HT1000 EHCI controllers.

* dm raid1: handle log failureJonathan Brassow2007-07-131-4/+8
| | | | | | | | | | | | | | | | | | | | When writing to a mirror, the log must be updated first. Failure to update the log could result in the log not properly reflecting the state of the mirror if the machine should crash. We change the return type of the rh_flush function to give us the ability to check if a log write was successful. If the log write was unsuccessful, we fail the writes to avoid the case where the log does not properly reflect the state of the mirror. A follow-up patch - which is dependent on the ability to requeue I/O's to core device-mapper - will requeue the I/O's for retry (allowing the mirror to be reconfigured.)

* dm raid1: handle resync failuresJonathan Brassow2007-07-131-3/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Device-mapper mirroring currently takes a best effort approach to recovery - failures during mirror synchronization are completely ignored. This means that regions are marked 'in-sync' and 'clean' and removed from the hash list. Future reads and writes that query the region will incorrectly interpret the region as in-sync. This patch handles failures during the recovery process. If a failure occurs, the region is marked as 'not-in-sync' (aka RH_NOSYNC) and added to a new list 'failed_recovered_regions'. Regions on the 'failed_recovered_regions' list are not marked as 'clean' upon removal from the list. Furthermore, if the DM_RAID1_HANDLE_ERRORS flag is set, the region is marked as 'not-in-sync'. This action prevents any future read-balancing from choosing an invalid device because of the 'not-in-sync' status. If "handle_errors" is not specified when creating a mirror (leaving the DM_RAID1_HANDLE_ERRORS flag unset), failures will be ignored exactly as they would be without this patch. This is to preserve backwards compatibility with user-space tools, such as 'pvmove'. However, since future read-balancing policies will rely on the correct sync status of a region, a user must choose "handle_errors" when using read-balancing.

* dm raid1: clear region outside spinlockJonathan Brassow2007-07-131-6/+6
| | | | | | | | | | | | | | | | | | | | | | A clear_region function is permitted to block (in practice, rare) but gets called in rh_update_states() with a spinlock held. The bits being marked and cleared by the above functions are used to update the on-disk log, but are never read directly. We can perform these operations outside the spinlock since the bits are only changed within one thread viz. - mark_region in rh_inc() - clear_region in rh_update_states(). So, we grab the clean_regions list items via list_splice() within the spinlock and defer clear_region() until we iterate over the list for deletion - similar to how the recovered_regions list is already handled. We then move the flush() call down to ensure it encapsulates the changes which are done by the later calls to clear_region().

| | | | | | | | * | [ARM] pxa: stop doing our own rtc management over suspendRussell King2007-07-121-10/+0

Firstly, we may not be using the internal RTC for time keeping; some platforms have an external RTC for this inspite of the PXA having an internal RTC. Secondly, the RTC library code handles updating system time on resume. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

This patch moves the specific code to pxa25x.c and pxa27x.c and makes dma.c more generic. 1. add pxa_init_dma() for dma initialization, the number of channels are passed in by the argument 2. add a "prio" field to the "struct pxa_dma_channel" for the channel priority, and is initialized in pxa_init_dma() 3. use a general priority comparison with the channels "prio" field so to remove the processor specific pxa_for_each_dma_prio macro, this is not lightning fast as the original one, but it is acceptable as it happens when requesting dma, which is usually not so performance critical Signed-off-by: eric miao <eric.miao@marvell.com> Acked-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
