* [PATCH] TTY layer buffering revampAlan Cox2006-01-101-11/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The API and code have been through various bits of initial review by serial driver people but they definitely need to live somewhere for a while so the unconverted drivers can get knocked into shape, existing drivers that have been updated can be better tuned and bugs whacked out. This replaces the tty flip buffers with kmalloc objects in rings. In the normal situation for an IRQ driven serial port at typical speeds the behaviour is pretty much the same, two buffers end up allocated and the kernel cycles between them as before. When there are delays or at high speed we now behave far better as the buffer pool can grow a bit rather than lose characters. This also means that we can operate at higher speeds reliably. For drivers that receive characters in blocks (DMA based, USB and especially virtualisation) the layer allows a lot of driver specific code that works around the tty layer with private secondary queues to be removed. The IBM folks need this sort of layer, the smart serial port people do, the virtualisers do (because a virtualised tty typically operates at infinite speed rather than emulating 9600 baud). Finally many drivers had invalid and unsafe attempts to avoid buffer overflows by directly invoking tty methods extracted out of the innards of work queue structs. These are no longer needed and all go away. That fixes various random hangs with serial ports on overflow. The other change in here is to optimise the receive_room path that is used by some callers. It turns out that only one ldisc uses receive room except asa constant and it updates it far far less than the value is read. We thus make it a variable not a function call. I expect the code to contain bugs due to the size alone but I'll be watching and squashing them and feeding out new patches as it goes. Because the buffers now dynamically expand you should only run out of buffering when the kernel runs out of memory for real. That means a lot of the horrible hacks high performance drivers used to do just aren't needed any more. Description: tty_insert_flip_char is an old API and continues to work as before, as does tty_flip_buffer_push() [this is why many drivers dont need modification]. It does now also return the number of chars inserted There are also tty_buffer_request_room(tty, len) which asks for a buffer block of the length requested and returns the space found. This improves efficiency with hardware that knows how much to transfer. and tty_insert_flip_string_flags(tty, str, flags, len) to insert a string of characters and flags For a smart interface the usual code is len = tty_request_buffer_room(tty, amount_hardware_says); tty_insert_flip_string(tty, buffer_from_card, len); More description! At the moment tty buffers are attached directly to the tty. This is causing a lot of the problems related to tty layer locking, also problems at high speed and also with bursty data (such as occurs in virtualised environments) I'm working on ripping out the flip buffers and replacing them with a pool of dynamically allocated buffers. This allows both for old style "byte I/O" devices and also helps virtualisation and smart devices where large blocks of data suddenely materialise and need storing. So far so good. Lots of drivers reference tty->flip.*. Several of them also call directly and unsafely into function pointers it provides. This will all break. Most drivers can use tty_insert_flip_char which can be kept as an API but others need more. At the moment I've added the following interfaces, if people think more will be needed now is a good time to say int tty_buffer_request_room(tty, size) Try and ensure at least size bytes are available, returns actual room (may be zero). At the moment it just uses the flipbuf space but that will change. Repeated calls without characters being added are not cumulative. (ie if you call it with 1, 1, 1, and then 4 you'll have four characters of space. The other functions will also try and grow buffers in future but this will be a more efficient way when you know block sizes. int tty_insert_flip_char(tty, ch, flag) As before insert a character if there is room. Now returns 1 for success, 0 for failure. int tty_insert_flip_string(tty, str, len) Insert a block of non error characters. Returns the number inserted. int tty_prepare_flip_string(tty, strptr, len) Adjust the buffer to allow len characters to be added. Returns a buffer pointer in strptr and the length available. This allows for hardware that needs to use functions like insl or mencpy_fromio.

* [PATCH] USB: file-storage gadget: Add reference count for childrenAlan Stern2006-01-041-13/+17
| | | | | | | | | | | | | | | | This patch (as601) adds a proper reference count to the file-storage gadget's main data structure, to keep track of references held by child devices (LUNs in this case). Before this, the driver would wait for each child to be released before unbinding. While there's nothing really wrong with that (you can't create a hang by doing "rmmod g_file_storage </sys/.../lun0/ro" since the open file will prevent rmmod from running), the code might as well follow the standard procedures. Besides, this shrinks the size of the structure by a few words... :-) Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] add usb transceiver set_suspend() methodJuha Yrj?l?2005-10-281-0/+4
| | | | | | | | | | | | | | When a USB device is put into suspend mode, the current drawn from VBUS has to be less than 500 uA. Some transceivers need to be put into a special power-saving mode to accomplish this, and won't have a separate OTG driver handling that. This adds a suspend method to the "otg_transceiver" struct -- misnamed, it's not only for OTG -- and calls it from the OMAP UDC driver.

| | | | | | | | | | | | | | The change to make DMA work two bytes at a time omitted an important tweak that affects the file_storage gadget: it needs to recognize when the host writes an odd number of bytes. (The network layer ignores such extra bytes.) This patch resolves that issue by checking the relevant bit and adjusting the rx byte count, so that for example a legal 13 byte request doesn't morph into an illegal 14 byte one any more.

* [PATCH] USB: Rename hcd->hub_suspend to hcd->bus_suspendAlan Stern2005-10-281-18/+4
| | | | | | | | | | | | | | | | This patch (as580) is perhaps the only result from the long discussion I had with David about his changes to the root-hub suspend/resume code. It renames the hub_suspend and hub_resume methods in struct usb_hcd to bus_suspend and bus_resume. These are more descriptive names, since the methods really do suspend or resume an entire USB bus, and less likely to be confused with the hub_suspend and hub_resume routines in hub.c. It also takes David's advice about removing the layer of bus glue, where those methods are called. And it implements a related change that David made to the other HCDs but forgot to put into dummy_hcd.

I submitted an ALSA patch for this http://thread.gmane.org/gmane.linux.alsa.devel/27804 issue and it was suggested that it might be preferable to change the register definitions to use u32. Most other subarches seem to use u32 for their register type, at least the ones which use a __REG macro (like the PXA) do. Nico indicated in the thread above that he wouldn't mind this patch. Changing the type required fixes for opposite warnings in the pxa2xx usb gadget code but that was the only new warning introduced on defconfig or lubbock, mainstone and our own PXA255 boards.

|/ | | | | | | | | | | | | | | | In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.

Also added is support for the (relatively new) _connect() and _disconnect() calls of the Gadget API.

* [PATCH] USB dummy_hcd: Use separate pdevs for HC and UDCAlan Stern2005-06-271-98/+133
| | | | | | | | | | | | | | This patch makes the dummy_hcd driver create separate platform devices for the emulated host controller and emulated device controller. This gives a more accurate simulation and will permit testing of situations where only one of the two devices is suspended. This also changes the name of the host controller platform device to match the name of the driver. That way the normal platform bus probe mechanism will handle binding the driver to the device.

* [PATCH] USB: dummy_hcd: USB_PORT_FEAT changed to USB_PORT_STATAlan Stern2005-06-271-27/+23
| | | | | | | | | | | | | | This patch makes some cosmetic changes to dummy_hcd: Minor alterations of comments and whitespace. Replace USB_PORT_FEAT_xxx with USB_PORT_STAT_xxx. This is appropriate as the values are stored in a status variable and they aren't feature indices. Also it allows the elimination of a bunch of awkward bit shift operations.

* [PATCH] USB dummy_hcd: Partial OTG emulationAlan Stern2005-06-271-2/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | Partial OTG support for dummy_hcd, mostly as a framework for further work. It emulates the new OTG flags in the host and peripheral frameworks, if that option is configured. But it's incomplete: - Resetting the peripheral needs to clear the OTG state bits; a second enumeration won't work correctly. - This stops modeling HNP right when roles should switch the first time. It should probably disconnect, then set the usb_bus.is_b_host and usb_gadget.is_a_peripheral flags; then it'd enumerate almost normally, except for the role reversal. Roles could then switch a second time, back to "normal" (with those flags cleared). - SRP should be modeled as "resume from port-unpowered", which is a state that usbcore doesn't yet use. HNP can be triggered by enabling the OTG whitelist and configuring a gadget driver that's not in that list; or by configuring Gadget Zero to identify itself as the HNP test device.
