• 714c1f5c1   MIPS: Octeon: Update DMA mapping operations for OCTEON II processors. ... Browse Code »

  OCTEON II has a new dma to phys mapping method for PCIe. Define
  OCTEON_DMA_BAR_TYPE_PCIE2 to denote this case, and handle it.

  OCTEON II also needs a swiotlb if the OHCI USB driver is enabled, so
  allocate this too.

• b93b2abce   MIPS: Octeon: Rewrite DMA mapping functions. ... Browse Code »

  All Octeon chips can support more than 4GB of RAM. Also due to how Octeon
  PCI is setup, even some configurations with less than 4GB of RAM will have
  portions that are not accessible from 32-bit devices.

  Enable the swiotlb code to handle the cases where a device cannot directly
  do DMA. This is a complete rewrite of the Octeon DMA mapping code.

• 2b5987aba   MIPS: Octeon: Allow more than 3.75GB of memory with PCIe ... Browse Code »

  We reserve the 3.75GB - 4GB region of PCIe address space for device to
  device transfers, making the corresponding physical memory under
  direct mapping unavailable for DMA.

  To allow for PCIe DMA to all physical memory we map this chunk of
  physical memory with BAR1. Because of the resulting discontinuity in
  the mapping function, we remove a page of memory at each end of the
  range so multi-page DMA buffers can never be allocated that span the
  range.

• 5b3b16880   MIPS: Add Cavium OCTEON processor support files to arch/mips/cavium-octeon. ... Browse Code »

  These are the rest of the new files needed to add OCTEON processor
  support to the Linux kernel. Other than Makefile and Kconfig which
  should be obvious, we have:

  csrc-octeon.c -- Clock source driver for OCTEON.
  dma-octeon.c -- Helper functions for mapping DMA memory.
  flash_setup.c -- Register on-board flash with the MTD subsystem.
  octeon-irq.c -- OCTEON interrupt controller managment.
  octeon-memcpy.S -- Optimized memcpy() implementation.
  serial.c -- Register 8250 platform driver and early console.
  setup.c -- Early architecture initialization.
  smp.c -- OCTEON SMP support.
  octeon_switch.S -- Scheduler context switch for OCTEON.
  c-octeon.c -- OCTEON cache controller support.
  cex-oct.S -- OCTEON cache exception handler.

  asm/mach-cavium-octeon/*.h -- Architecture include files.
