  • c9d95fbe5   ARM: convert PCI defines to variables ... Browse Code »

    Convert PCIBIOS_MIN_IO and PCIBIOS_MIN_MEM to variables to allow
    multi-platform builds. This also removes the requirement for a platform to
    have a mach/hardware.h.

    The default values for i/o and mem are 0x1000 and 0x01000000, respectively.
    Per Arnd Bergmann, other values are likely to be incorrect, but this commit
    does not try to address that issue.

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

  • 23759dc64   [ARM] 3439/2: xsc3: add I/O coherency support ... Browse Code »

    Patch from Lennert Buytenhek

    This patch adds support for the I/O coherent cache available on the
    xsc3. The approach is to provide a simple API to determine whether the
    chipset supports coherency by calling arch_is_coherent() and then
    setting the appropriate system memory PTE and PMD bits. In addition,
    we call this API on dma_alloc_coherent() and dma_map_single() calls.
    A generic version exists that will compile out all the coherency-related
    code that is not needed on the majority of ARM systems.

    Note that we do not check for coherency in the dma_alloc_writecombine()
    function as that still requires a special PTE setting. We also don't
    touch dma_mmap_coherent() as that is a special ARM-only API that is by
    definition only used on non-coherent system.

  • 532bda5d9   [ARM] 3438/1: ixp23xx: add pci slave support ... Browse Code »

    Patch from Lennert Buytenhek

    On the Double Espresso board, the IXP2350s are PCI slave devices and
    we skip calling pci_common_init() as that enumerates the bus. But even
    though we are a PCI slave device, there is still some PCI-related setup
    that has to be done.

    Create ixp23xx_pci_common_init(), move the common initialisation bits
    there, and have this function called from both the PCI master and the
    PCI slave init path.

  • c47130743   [ARM] 3388/1: ixp23xx: add core ixp23xx support ... Browse Code »

    Patch from Lennert Buytenhek

    This patch adds support for the Intel ixp23xx series of CPUs. The
    ixp23xx is an XSC3 based CPU with 512K of L2 cache, a 64bit 66MHz PCI
    interface, two DDR RAM interfaces, QDR RAM interfaces, two gigabit
    MACs, two 10/100 MACs, expansion bus, four microengines, a Media and
    Switch Fabric unit almost identical to the one on the ixp2400, two
    xscale (8250ish) UARTs and a bunch of other stuff.

    This patch adds the core ixp23xx support code, and support for the
    ADI Engineering Roadrunner, Intel IXDP2351, and IP Fabrics Double
    Espresso platforms.
