  • 94859308a   w1: new w1_ds2406 driver ... Browse Code »

    Some preliminary work at making use of this driver led me to implement
    CRC-16 checks on read and write to deal with the occasional glitchiness of
    the 1-Wire bus. The revised driver (attached) returns an I/O error if the
    CRC check fails. When reading the chip's state, either you get a valid
    indication or you get an I/O error. When changing its state, either the
    change is successful or an I/O error is returned.

  • 8a0427d19   w1: optional bundling of netlink kernel replies ... Browse Code »

    Applications can submit a set of commands in one packet to the kernel,
    and in some cases it is required such as reading the temperature
    sensor results. This adds an option W1_CN_BUNDLE to the flags of
    cn_msg to request the kernel to reply in one packet for efficiency.

    The cn_msg flags now check for unknown flag values and return an error
    if one is seen. See "Proper handling of unknown flags in system
    calls" http://lwn.net/Articles/588444/

    This corrects the ack values returned as per the protocol standard,
    namely the original ack for status messages and seq + 1 for all others
    such as the data returned from a read.

    Some of the common variable names have been standardized as follows.
    struct cn_msg *cn
    struct w1_netlink_msg *msg
    struct w1_netlink_cmd *cmd
    struct w1_master *dev

    When an argument and a function scope variable would collide, add req_
    to the argument.

  • 17fecb558   w1: DS2423 counter driver and documentation ... Browse Code »

    This is a 1-wire/w1 DS2423 slave driver for reading the values from all 4
    counters available DS2423 devices by using standard w1_slave file. In
    ds2423 the counters are tied to ram pages 12-15 in and each of those
    ram-pages. Each of these counter values (and asoociated ram page values)
    are represented as a own line in w1_slave file. Driver has been tested on
    mips and x86.

    usage example:
    cat /sys/bus/w1/devices/1d-00000009b964/w1_slave

    Below you will find an updated version from the original series bunching all patches into one big patch
    updating broken web addresses that are located in Documentation/*
    Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult,
    the best way to deal with these is to use web.archive.org to locate these addresses that are outdated.
    Now there are also some addresses pointing to .spec files some are located, but some(after searching
    on the companies site)where still no where to be found. In this case I just changed the address
    to the company site this way the users can contact the company and they can locate them for the users.

  • 0314b020c   ds2482: Discard obsolete detect method ... Browse Code »

    There is no point in implementing a detect callback for the DS2482, as
    this device can't be detected. It was there solely to handle "force"
    module parameters to instantiate devices, but now we have a better sysfs
    interface that can do the same.

    So we can get rid of the ugly module parameters and the detect callback.
    This shrinks the binary module size by 21%.

    There are three types of messages between w1 core and userspace:
    1. Events. They are generated each time new master or slave device found
    either due to automatic or requested search.
    2. Userspace commands. Includes read/write and search/alarm search comamnds.
    3. Replies to userspace commands.

  • f522d2396   [PATCH] w1: Added default generic read/write operations. ... Browse Code »

    Special file in each w1 slave device's directory called "rw" is created
    each time new slave and no appropriate w1 family is registered.
    "rw" file supports read and write operations, which allows to perform
    almost any kind of operations. Each logical operation is a transaction
    in nature, which can contain several (two or one) low-level operations.
    Let's see how one can read EEPROM context:
    1. one must write control buffer, i.e. buffer containing command byte
    and two byte address. At this step bus is reset and appropriate device
    is selected using either W1_SKIP_ROM or W1_MATCH_ROM command.
    Then provided control buffer is being written to the wire.
    2. reading. This will issue reading eeprom response.

    It is possible that between 1. and 2. w1 master thread will reset bus for
    searching and slave device will be even removed, but in this case 0xff will
    be read, since no device was selected.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.
