  • 542c1020a   MIPS: Add CONFIG_CPU_R5500 for NEC VR5500 series processors ... Browse Code »

    We already have sufficient infrastructure to support VR5500 and VR5500A
    series processors. Here's a Makefile support to make it selectable by
    ports, and enable it for NEC EMMA2RH Markeins board.

    This patch also fixes a confused target help, and adds 1Gb PageMask bits
    supported by VR5500 and its variants.

    We were getting away with this for so long only because the only platform
    with a non-empty plat_unmap_dma_mem() doesn't call dma_sync_sg_for_cpu()
    and dma_sync_sg_for_device() from its commonly used drivers.

  • e66ddf1a4   mips: use generic show_mem() ... Browse Code »

    Remove arch-specific show_mem() in favor of the generic version.

    This also removes the following redundant information display:

    - pages in swapcache, printed by show_swap_cache_info()

    where show_mem() calls show_free_areas(), which calls
    show_swap_cache_info().

    And show_mem() does now actually print something on configurations
    with multiple nodes.

  • 8d8bb39b9   dma-mapping: add the device argument to dma_mapping_error() ... Browse Code »

    Add per-device dma_mapping_ops support for CONFIG_X86_64 as POWER
    architecture does:

    This enables us to cleanly fix the Calgary IOMMU issue that some devices
    are not behind the IOMMU (http://lkml.org/lkml/2008/5/8/423).

    I think that per-device dma_mapping_ops support would be also helpful for
    KVM people to support PCI passthrough but Andi thinks that this makes it
    difficult to support the PCI passthrough (see the above thread). So I
    CC'ed this to KVM camp. Comments are appreciated.

    A pointer to dma_mapping_ops to struct dev_archdata is added. If the
    pointer is non NULL, DMA operations in asm/dma-mapping.h use it. If it's
    NULL, the system-wide dma_ops pointer is used as before.

    If it's useful for KVM people, I plan to implement a mechanism to register
    a hook called when a new pci (or dma capable) device is created (it works
    with hot plugging). It enables IOMMUs to set up an appropriate
    dma_mapping_ops per device.

    The major obstacle is that dma_mapping_error doesn't take a pointer to the
    device unlike other DMA operations. So x86 can't have dma_mapping_ops per
    device. Note all the POWER IOMMUs use the same dma_mapping_error function
    so this is not a problem for POWER but x86 IOMMUs use different
    dma_mapping_error functions.

    The first patch adds the device argument to dma_mapping_error. The patch
    is trivial but large since it touches lots of drivers and dma-mapping.h in
    all the architecture.

    This patch:

    dma_mapping_error() doesn't take a pointer to the device unlike other DMA
    operations. So we can't have dma_mapping_ops per device.

    Note that POWER already has dma_mapping_ops per device but all the POWER
    IOMMUs use the same dma_mapping_error function. x86 IOMMUs use device
    argument.

  • 17f61e61b   [MIPS] Make two functions static ... Browse Code »

    The following routines

    uasm_rel_highest()
    uasm_rel_higher()

    are needlessly defined global. This patch makes them static.

    Compile-tested using a customized config for the Malta board. Booting
    the same board up to the shell prompt was also successful with this
    patch applied.

    Spotted by sparse.

  • 2eaa7ec28   [MIPS] Handle I-cache coherency in flush_cache_range() ... Browse Code »

    So far flush_cache_range() did't consider the I-cache largely because it
    did rarely ever matter to real world code. This was working primarily
    because normally code and data are don't share the same pages - with the
    exception of MIPS16 code which uses address constants embedded between
    the code. The following sequence of events may break the code:

    o MIPS16 executable being loaded
    o dynamic linker relocates the address constants embedded into the code:
    o Uses mprotect(2) to make code pages PROT_READ|PROT_WRITE
    o Performs the actual relocations by writing to the pages which likely
    are COW. Because no PROT_EXEC is set I-cache coherence will not be
    considered.
    o Uses mprotect(2) to switch code pages back to PROT_READ|PROT_EXEC.
    This results in a call to flush_cache_range() which also does not
    consider I-caches.
    o => executing the page just having been relocated may now result in the
    I-cache getting refilled with stale data from memory.

  • e30ec4525   [MIPS] Split the micro-assembler from tlbex.c. ... Browse Code »

    This patch moves the micro-assembler in a separate implementation, as
    it is useful for further run-time optimizations. The only change in
    behaviour is cutting down printk noise at kernel startup time.

    Checkpatch complains about macro parameters which aren't protected by
    parentheses. I believe this is a flaw in checkpatch, the paste operator
    used in those macros won't work with parenthesised parameters.

    They are essentially identical to the Au1200 except for the Au1210
    which has a different SoC-ID in the PRId register [bits 31:24].
    The Au1250 is a "Au1200 V0.2".
