  • 1b0fac458   dma-mapping: prevent dma dependent code from linking on !HAS_DMA archs ... Browse Code »

    Continuing the work started in 411f0f3edc141a582190d3605cadd1d993abb6df ...

    This enables code with a dma path, that compiles away, to build without
    requiring additional code factoring. It also prevents code that calls
    dma_alloc_coherent and dma_free_coherent from linking whereas previously
    the code would hit a BUG() at run time. Finally, it allows archs that set
    !HAS_DMA to delete their asm/dma-mapping.h file.

  • 9ac7849e3   devres: device resource management ... Browse Code »

    Implement device resource management, in short, devres. A device
    driver can allocate arbirary size of devres data which is associated
    with a release function. On driver detach, release function is
    invoked on the devres data, then, devres data is freed.

    devreses are typed by associated release functions. Some devreses are
    better represented by single instance of the type while others need
    multiple instances sharing the same release function. Both usages are
    supported.

    devreses can be grouped using devres group such that a device driver
    can easily release acquired resources halfway through initialization
    or selectively release resources (e.g. resources for port 1 out of 4
    ports).

    This patch adds devres core including documentation and the following
    managed interfaces.

    * alloc/free : devm_kzalloc(), devm_kzfree()
    * IO region : devm_request_region(), devm_release_region()
    * IRQ : devm_request_irq(), devm_free_irq()
    * DMA : dmam_alloc_coherent(), dmam_free_coherent(),
    dmam_declare_coherent_memory(), dmam_pool_create(),
    dmam_pool_destroy()
    * PCI : pcim_enable_device(), pcim_pin_device(), pci_is_managed()
    * iomap : devm_ioport_map(), devm_ioport_unmap(), devm_ioremap(),
    devm_ioremap_nocache(), devm_iounmap(), pcim_iomap_table(),
    pcim_iomap(), pcim_iounmap()

    These are the last conversions of pci_set_dma_mask(),
    pci_set_consistent_dma_mask() and pci_dma_supported() to use DMA_xBIT_MASK
    constants from linux/dma-mapping.h

    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!
