  • b17349133   PNP: remove null pointer checks ... Browse Code »

    Remove some null pointer checks. Null pointers in these areas indicate
    programming errors, and I think it's better to oops immediately rather
    than return an error that is easily ignored.

  • 8f81dd149   PNP: notice whether we have PNP devices (PNPBIOS or PNPACPI) ... Browse Code »

    This series converts i386 and x86_64 legacy serial ports to be platform
    devices and prevents probing for them if we have PNP.

    This prevents double discovery, where a device was found both by the legacy
    probe and by 8250_pnp.

    This also prevents the serial driver from claiming IRDA devices (unless they
    have a UART PNP ID). The serial legacy probe sometimes assumed the wrong IRQ,
    so the user had to use "setserial" to fix it.

    Removing the need for setserial to make IRDA devices work seems good, but it
    does break some things. In particular, you may need to keep setserial from
    poking legacy UART stuff back in by doing something like "dpkg-reconfigure
    setserial" with the "kernel" option. Otherwise, the setserial-discovered
    "UART" will claim resources and prevent the IRDA driver from loading.

    This patch:

    If we can discover devices using PNP, we can skip some legacy probes. This
    flag ("pnp_platform_devices") indicates that PNPBIOS or PNPACPI is enabled and
    should tell us about builtin devices.

  • 2e17c5508   init dma masks in pnp_dev ... Browse Code »

    PNP now initializes device dma masks, which prevents oopses when generic
    dma calls are made using pnp device nodes.

    This assumes PNP only uses ISA DMA, with 24 bit addresses; and that it's
    safe to init those masks for all devices (rather than finding out which
    devices have been assigned DMA channels, and handling only those).

  • b449f63c8   [PATCH] drivers/pnp/: cleanups ... Browse Code »

    This patch contains the following possible cleanups:
    - make needlessly global code static
    - #if 0 the following unused global function:
    - core.c: pnp_remove_device
    - #if 0 the following unneeded EXPORT_SYMBOL's:
    - card.c: pnp_add_card
    - card.c: pnp_remove_card
    - card.c: pnp_add_card_device
    - card.c: pnp_remove_card_device
    - card.c: pnp_add_card_id
    - core.c: pnp_register_protocol
    - core.c: pnp_unregister_protocol
    - core.c: pnp_add_device
    - core.c: pnp_remove_device
    - pnpacpi/core.c: pnpacpi_protocol
    - driver.c: pnp_add_id
    - isapnp/core.c: isapnp_read_byte
    - manager.c: pnp_auto_config_dev
    - resource.c: pnp_register_dependent_option
    - resource.c: pnp_register_independent_option
    - resource.c: pnp_register_irq_resource
    - resource.c: pnp_register_dma_resource
    - resource.c: pnp_register_port_resource
    - resource.c: pnp_register_mem_resource

    Note that this patch #if 0's exactly one functions and removes no
    functions. Most it does is the #if 0 of EXPORT_SYMBOL's, so if any modular
    code will use any of them, re-adding will be trivial.

    Modular ISAPnP might be interesting in some cases, but this is more legacy
    code. If someone would work on it to sort all the issues out (starting
    with the point that most users of __ISAPNP__ will have to be fixed)
    re-enabling the required EXPORT_SYMBOL's won't be hard for him.

    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.

    Let it rip!
