  • 709ea543b   stdio: Pass device pointer to stdio methods ... Browse Code »
    44

    At present stdio device functions do not get any clue as to which stdio
    device is being acted on. Some implementations go to great lengths to work
    around this, such as defining a whole separate set of functions for each
    possible device.

    For driver model we need to associate a stdio_dev with a device. It doesn't
    seem possible to continue with this work-around approach.

    Instead, add a stdio_dev pointer to each of the stdio member functions.

    Note: The serial drivers have the same problem, but it is not strictly
    necessary to fix that to get driver model running. Also, if we convert
    serial over to driver model the problem will go away.

    Code size increases by 244 bytes for Thumb2 and 428 for PowerPC.

  • 91d0be1dd   stdio: Remove redundant code around stdio_register() calls ... Browse Code »

    There is no point in setting a structure's memory to NULL when it has
    already been zeroed with memset().

    Also, there is no need to create a stub function for stdio to call - if the
    function is NULL it will not be called.

    This is a clean-up, with no change in functionality.

  • c95e2b9ea   console: usb: kbd: To fix slow TFTP booting ... Browse Code »

    TFTP booting is slow when a USB keyboard is installed and
    stdin has usbkbd added.
    This fix is to change Ctrl-C polling for USB keyboard to every second
    when NET transfer is running.
    My previous patch is expected to be put into usb_kbd_testc(). But it went
    into usb_kbd_getc() after applied.
    This patch is to put change in correct place.

  • 5da2dc978   usb: workaround non-working keyboards. ... Browse Code »

    If the USB keyboard is not answering properly the first request on its
    interrupt endpoint, just skip it and try the next one.

    This workarounds an issue with a wireless mouse dongle which presents
    itself both as a keyboard and a mouse but has a non-functional keyboard
    interface.

  • 4151a400c   USB: add arrow key support to usb_kbd ... Browse Code »

    Check for scancodes for arrow keys and map them to ^F/^B, ^N/^P.
    Control characters are used instead of ANSI sequence because the
    queueing code in usb_kbd doesn't handle the data increase when one
    keypress generates 3 keycodes. The real fix is to convert this driver
    to use the input subsystem and queue, but this allows arrow keys to
    work until this driver is converted.

  • 8f8bd565f   USB Consolidate descriptor definitions ... Browse Code »

    The header files usb.h and usbdescriptors.h have the same nameed
    structure definitions for

    usb_config_descriptor
    usb_interface_descriptor
    usb_endpoint_descriptor
    usb_device_descriptor
    usb_string_descriptor

    These are out right duplicates in usb.h

    usb_device_descriptor
    usb_string_descriptor

    This one has extra unused elements

    usb_endpoint_descriptor

    unsigned char bRefresh
    unsigned char bSynchAddress;

    These in usb.h have extra elements at the end of the usb 2.0
    specified descriptor and are used.

    usb_config_descriptor
    usb_interface_descriptor

    The change is to consolidate the definition of the descriptors
    to usbdescriptors.h. The dublicates in usb.h are removed.
    The extra element structure will have their name shorted by
    removing the '_descriptor' suffix.

    So

    usb_config_descriptor -> usb_config
    usb_interface_descriptor -> usb_interface

    For these, the common descriptor elements are accessed now
    by an element 'desc'.

    As an example

    - if (iface->bInterfaceClass != USB_CLASS_HUB)
    + if (iface->desc.bInterfaceClass != USB_CLASS_HUB)

    This has been compile tested on MAKEALL arm, ppc and mips.

  • 52cb4d4fb   stdio/device: rework function naming convention ... Browse Code »

    So far the console API uses the following naming convention:

    ======Extract======
    typedef struct device_t;

    int device_register (device_t * dev);
    int devices_init (void);
    int device_deregister(char *devname);
    struct list_head* device_get_list(void);
    device_t* device_get_by_name(char* name);
    device_t* device_clone(device_t *dev);
    =======

    which is too generic and confusing.

    Instead of using device_XX and device_t we change this
    into stdio_XX and stdio_dev

    This will also allow to add later a generic device mechanism in order
    to have support for multiple devices and driver instances.

  • 1eb734fed   usb : usb_kbd : Populating 'priv' member of USB keyboard device_t structure ... Browse Code »

    This patch populates the 'priv' field of the USB keyboard device_t
    structure. The 'priv' field is populated with the address of the
    'struct usb_device' structure that represents the USB device.

    The 'priv' field can then be used in the 'usb_event_poll' function to
    determine the USB device that requires to be polled. An
    example of its usage in 'usb_event_poll' function is as below.

    device_t *dev;
    struct usb_device *usb_kbd_dev;

    dev = device_get_by_name("usbkbd");
    usb_kbd_dev = (struct usb_device *)dev->priv;
    iface = &usb_kbd_dev->config.if_desc[0];

    This commit gets rid of a huge amount of silly white-space issues.
    Especially, all sequences of SPACEs followed by TAB characters get
    removed (unless they appear in print statements).

    Also remove all embedded "vim:" and "vi:" statements which hide
    indentation problems.
