  • a83f98231   [SPARC]: Fix OF register translations under sub-PCI busses. ... Browse Code »

    There is an implicit assumption in the code that ranges will translate
    to something that can fit in 2 32-bit cells, or a 64-bit value. For
    certain kinds of things below PCI this isn't necessarily true.

    Here is what the relevant OF device hierarchy looks like for one of
    the serial controllers on an Ultra5:

    Node 0xf005f1e0
    ranges: 00000000.00000000.00000000.000001fe.01000000.00000000.01000000
    01000000.00000000.00000000.000001fe.02000000.00000000.01000000
    02000000.00000000.00000000.000001ff.00000000.00000001.00000000
    03000000.00000000.00000000.000001ff.00000000.00000001.00000000
    device_type: 'pci'
    model: 'SUNW,sabre'

    Node 0xf005f9d4
    device_type: 'pci'
    model: 'SUNW,simba'

    Node 0xf0060d24
    ranges: 00000010.00000000 82010810.00000000.f0000000 01000000
    00000014.00000000 82010814.00000000.f1000000 00800000
    name: 'ebus'

    Node 0xf0062dac
    reg: 00000014.003083f8.00000008 --> 0x1ff.f13083f8
    device_type: 'serial'
    name: 'su'

    So the correct translation here is:

    1) Match "su" register to second ranges entry of 'ebus', which translates
    into a PCI triplet "82010814.00000000.f1000000" of size 00800000, which
    gives us "82010814.00000000.f13083f8".

    2) Pass-through "SUNW,simba" since it lacks ranges property

    3) Match "82010814.00000000.f13083f8" to third ranges property of PCI
    controller node 'SUNW,sabre', and we arrive at the final physical
    MMIO address of "0x1fff13083f8".

    Due to the 2-cell assumption, we couldn't translate to a PCI 3-cell
    value, and we couldn't perform a pass-thru on it either.

    It was easiest to just stop splitting the ranges application operation
    between two methods, ->map and ->translate, and just let ->map do all
    the work. That way it would work purely on 32-bit cell arrays instead
    of having to "return" some value like a u64.

    It's still not %100 correct because the out-of-range check is still
    done using the 64 least significant bits of the range and address.
    But it does work for all the cases I've thrown at it so far.

  • 894673ee6   [PATCH] tty: Remove include of screen_info.h from tty.h ... Browse Code »

    screen_info.h doesn't have anything to do with the tty layer and shouldn't be
    included by tty.h. This patches removes the include and modifies all users to
    directly include screen_info.h. struct screen_info is mainly used to
    communicate with the console drivers in drivers/video/console. Note that this
    patch touches every arch and I have no way of testing it. If there is a
    mistake the worst thing that will happen is a compile error.

  • 347ce434d   [PATCH] zoned vm counters: conversion of nr_pagecache to per zone counter ... Browse Code »

    Currently a single atomic variable is used to establish the size of the page
    cache in the whole machine. The zoned VM counters have the same method of
    implementation as the nr_pagecache code but also allow the determination of
    the pagecache size per zone.

    Remove the special implementation for nr_pagecache and make it a zoned counter
    named NR_FILE_PAGES.

    Updates of the page cache counters are always performed with interrupts off.
    We can therefore use the __ variant here.

  • 8f96cd1a6   [SPARC]: sparc32 side of of_device layer IRQ resolution. ... Browse Code »

    Happily, life is much simpler on 32-bit sparc systems.
    The "intr" property, preferred over the "interrupts"
    property is used-as. Some minor translations of this
    value happen on sun4d systems.

    The stage is now set to rewrite the sparc serial driver
    probing to use the of_driver framework, and then to convert
    all SBUS, EBUS, and ISA drivers in-kind so that we can nuke
    all those special bus frameworks.

  • c6387a48c   [SPARC]: Kill __irq_itoa(). ... Browse Code »

    This ugly hack was long overdue to die.

    It was a way to print out Sparc interrupts in a more freindly format,
    since IRQ numbers were arbitrary opaque 32-bit integers which vectored
    into PIL levels. These 32-bit integers were not necessarily in the
    0-->NR_IRQS range, but the PILs they vectored to were.

    The idea now is that we will increase NR_IRQS a little bit and use a
    virtualreal IRQ number mapping scheme similar to PowerPC.

    That makes this IRQ printing hack irrelevant, and furthermore only a
    handful of drivers actually used __irq_itoa() making it even less
    useful.
