This patch (as841) removes from usbcore a couple of support routines meant to help with bandwidth allocation. With the changes to uhci-hcd in the previous patch, these routines are no longer used anywhere. Also removed is the CONFIG_USB_BANDWIDTH option; it no longer does anything and is no longer needed since the HCDs now handle bandwidth issues correctly.

Thanks to Johannes Hölzl <johannes.hoelzl@gmx.de> for fixing a few things and getting it all working properly. This adds support for dynamic usb ids to the usb serial core. The file "new_id" will show up under the usb serial driver, not the usb driver associated with the usb-serial driver (yeah, it can be a bit confusing at first glance...) This patch also modifies the USB core to allow the usb-serial core to reuse much of the dynamic id logic.

2007-02-07rndis_host learns ActiveSync basicsOle Andre Vadla Ravnas1-8/+20
Windows Mobile 5 based devices described as supporting "ActiveSync": - Speak RNDIS but lack the CDC and union descriptors. This patch updates the cdc ethernet code to fake ACM descriptors we need. - Require RNDIS_MSG_QUERY messages to include a buffer of the size the response should generate. This patch updates the rndis host code to pass this will-be-ignored data. The resulting RNDIS host code has been reported to work with several WM5 based devices. (Note that a fancier patch is available at synce.sf.net.) Some bugfixes, affecting not just ActiveSync: (a) when cleaning up after RNDS init fails, scrub the second interface just like cdc_ether does, so disconnect won't oops. (b) handle peripherals that use the pad-to-end-of-packet option; some devices can't talk to us if that option doesn't work. (c) when choosing configurations, don't forget about an RNDIS config just because the RNDIS driver is dynamically linked. Cleanup, streamlining, bugfixes, Kconfig, and matching hub driver update. Also for paranoia's sake, refuse to talk to something that looks like a real modem instead of RNDIS.

2006-12-01USB: keep count of unsuspended childrenAlan Stern2-11/+37
This patch (as818b) simplifies autosuspend processing by keeping track of the number of unsuspended children of each USB hub. This will permit us to avoid a good deal of unnecessary work all the time; we will no longer have to create a bunch of workqueue entries to carry out autosuspend requests, only to have them fail because one of the hub's children isn't suspended. The basic idea is simple. There already is a usage counter in the usb_device structure for preventing autosuspends. The patch just increments that counter for every unsuspended child. There's only one tricky part: When a device disconnects we need to remember whether it was suspended at the time (leave the counter alone) or not (decrement the counter).

2006-12-01USB hub: simplify remote-wakeup handlingAlan Stern1-23/+20
This patch (as817) simplifies the remote-wakeup processing in the hub driver. Now instead of using a specialized code path, it relies on the standard USB resume routines. The hub_port_resume() function does an initial get_port_status() to see whether the port has already resumed itself (as it does when a remote-wakeup request is sent). This will slow down handling of other resume events slightly, but not enough to matter. The patch also changes the hub_port_status() routine, making it return an error if a short reply is received.

2006-12-01USB: makes usb_endpoint_* functions inline.Luiz Fernando N. Capitulino1-144/+0
We have no benefits of having the usb_endpoint_* functions as functions, but making them inline saves text and data segment sizes: text data bss dec hex filename 14893634 3108770 1108840 19111244 1239d4c vmlinux.func 14893185 3108566 1108840 19110591 1239abf vmlinux.inline This is the result of a 2.6.19-rc3 kernel compiled with GCC 4.1.1 without CONFIG_MODULES, CONFIG_CC_OPTIMIZE_FOR_SIZE, CONFIG_REGPARM options set. USB support is fully enabled (while most of the other drivers are not), and that kernel has most of the USB code ported to use the endpoint functions. That happens because a call to those functions are expensive (in terms of bytes), while the function's size is smaller or have the same 'size' of the call. Signed-off-by: Luiz Fernando N.

2006-12-01USB core: don't match interface descriptors for vendor-specific devicesAlan Stern1-1/+21
This patch (as804) makes USB driver matching ignore the interface class, subclass, and protocol if the device class is Vendor Specific. Drivers can override this policy by specifying a Vendor ID as part of the match; then vendor-specific matches are allowed. Linus Walleij has reported a problem this patch fixes. When a particular mass-storage device is switched from mass-storage mode to Media Transfer Protocol, the interface class remains set to mass-storage and usb-storage binds to it erroneously, even though the device class changes to Vendor-Specific. This may cause a problem for some drivers until their match records can be updated to include Vendor IDs. But if it does, then those records were broken to begin with.

2006-12-01usb hub: fix root hub code so it takes more than 15 devices per root hubinaky@linux.intel.com2-2/+9
Wireless USB Host Controllers accept a large number of devices per host, which shows up as a large number of ports in its root hub. When the number of ports in a hub device goes over 16, the activation of the hub fails with the cryptic message in klogd. hub 2-0:1.0: activate --> -22 Following this further, it was seen that: hub_probe() hub_configure() generates pipe number pseudo allocates buffer 'maxp' bytes in size using usb_maxpacket() The endpoint descriptor for a root hub interrupt endpoint is declared in drivers/usb/core/hcd.c:hs_rh_config_descriptor and declares it to be size two (supporting 15 devices max). hub_activate() usb_hcd_submit_urb() rh_urb_enqueue() urb->pipe is neither int nor ctl, so it errors out rh_queue_status() Returns -EINVAL because the buffer length is smaller than the minimum needed to report all the hub port bits as in accordance with USB2.0[11.12.3]. There has to be trunc((PORTS + 1 + 7) / 8) bytes of space at least. Alan Stern confirmed that the reason for reading maxpktsize and not the right amount is because some hubs are known to return more data and thus cause overflow. So this patch simply changes the code to make the interrupt endpoint's max packet size be at least the minimum required by USB_MAXCHILDREN (instead of a fixed magic number) and add documentation for that. This way we are always ahead of the limit. Signed-off-by: Inaky Perez-Gonzalez <inaky.perez-gonzalez@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-12-01usb/hub: allow hubs up to 31 childreninaky@linux.intel.com1-1/+1
Current Wireless USB host hardware (Intel i1480 for example) allows up to 22 devices to connect, thus bringing up the max number of children in the WUSB Host Controller to 22 'fake' ports. Upcoming hardware might raise that limit. Makes almost no difference to go to 31, as the bit arrays are byte-aligned (plus an extra bit in general), so 22 bits fit in 4 bytes as 31 do. As well, the only other array that depends on USB_MAXCHILDREN is 'struct usb_hub->indicator'. By declaring it 'u8' instead of 'enum hub_led_mode', we reduce the size of each entry from 4 bytes (in i386) to 1, which will add as we when are doubling USB_MAXCHILDREN (with 16 the size of that array is 64 bytes, with 31 would be 128; by using u8 that goes down to 31 bytes).

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells5-18/+14
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.
