      Ian Abbott authored
      When allocating a buffer to support asynchronous comedi commands, if a
      DMA coherent buffer was requested but `CONFIG_HAS_DMA` is undefined,
      bail out of local helper function `__comedi_buf_alloc()` with an error
      message.

      staging: comedi: ni_mio_common: only do counter commands for ni_pcimio · bd304a73
      Ian Abbott authored
      "ni_mio_common.c" holds common code included by "ni_pcimio.c",
      "ni_atmio.c" and "ni_mio_cs.c", including a common initialization
      function `ni_E_init()`.  Amongst other things, this initializes some
      counter subdevices to support comedi instructions and asynchronous
      commands.  However, even though it sets up the handlers to support
      asynchronous commands on these subdevices, the handlers will return an
      error unless the `PCIDMA` macro is defined (which is defined only in
      "ni_pcimio.c").  If the `PCIDMA` macro is not defined, the comedi core
      will needlessly allocate buffers to support the asynchronous commands.
      Also, `s->async_dma_dir` is set to `DMA_BIDIRECTIONAL`, causing the
      physical pages for the buffers to be allocated using
      `dma_alloc_coherent()`.
      
      If the comedi core cannot call `dma_alloc_coherent()` because
      `CONFIG_HAS_DMA` is not defined, it will fail to allocate the buffers,
      which ultimately causes `ni_E_init()` to fail.
      
      Avoid the wastage and prevent the failure by only setting up
      asynchronous command support for the counter subdevices if the `PCIDMA`
      macro is defined.

      staging: comedi: work without HAS_DMA · 4efc4bbd
      Ian Abbott authored
      The core "comedi" module and the "mite" helper module for NI PCI devices
      both have calls to `dma_alloc_coherent()` and `dma_free_coherent()`.
      Those functions are only available if `CONFIG_HAS_DMA` is defined.
      
      Apart from the "mite" module, the functions are only called for comedi
      drivers that set `s->async_dma_dir` (where `s` is a pointer to a `struct
      comedi_subdevice`) to anything other than `DMA_NONE`.
      
      Change local helper functions `__comedi_buf_alloc()` and
      `__comedi_buf_free()` to only call `dma_alloc_coherent()` and
      `dma_free_coherent()` if `CONFIG_HAS_DMA` is defined.
      
      Change the "Kconfig" to make the following configuration options depend
      on `HAS_DMA`:
      
      `COMEDI_MITE` - builds the "mite" module.
      `COMEDI_NI_6527` - selects `COMEDI_MITE`.
      `COMEDI_NI_65XX` - selects `COMEDI_MITE`.
      `COMEDI_NI_670X` - selects `COMEDI_MITE`.
      `COMEDI_NI_LABPC_PCI` - selects `COMEDI_MITE`.
      `COMEDI_NI_PCIDIO` - selects `COMEDI_MITE`.
      `COMEDI_NI_TIOCMD` - selects `COMEDI_MITE`.
      `COMEDI_NI_660X` - selects `COMEDI_NI_TIOCMD`,
                         sets `s->async_dma_dir`.
      `COMEDI_NI_PCIMIO` - selects `COMEDI_NI_TIOCMD`,
                           sets `s->async_dma_dir`.

      staging: comedi: allow buffer resize if previous resize failed · b3fab427
      Ian Abbott authored
      When a comedi device is successfully attached, those subdevices that
      support asynchronous commands will have had buffers allocated
      successfully.  It is possible to resize the buffers afterwards, but if
      the resize fails the subdevice is left with no buffer
      (`s->async->prealloc_buf == NULL`).  Currently, this also causes any
      subsequent attempts to resize the buffer to fail with an error, which
      seems like a bad idea.
      
      Remove the check in `resize_async_buffer()` that causes the resize to
      fail if the subdevice currently has no buffer (presumably due to the
      failure of a previous resize attempt).  Callers of
      `resize_async_buffer()` have already checked that the subdevice is
      allowed to have a buffer.

      staging: comedi: ni_labpc: fix build when VIRT_TO_BUS is not defined · 1581a035
      H Hartley Sweeten authored
      After merging the final tree, the next-20130424 build (powerpc
      allyesconfig) failed like this:
      
      drivers/staging/comedi/drivers/ni_labpc.c: In function 'labpc_ai_cmd':
      drivers/staging/comedi/drivers/ni_labpc.c:980:9: error:
          implicit declaration of function 'virt_to_bus'
         [-Werror=implicit-function-declaration]
      
      The virt_to_bus() is only needed for the ISA DMA support in this driver.
      
      On powerpc, CONFIG_COMEDI_NI_LABPC_ISA cannot be enabled due to the
      depends on VIRT_TO_BUS but the PCI driver, ni_labpc_pci, can be enabled.
      That driver uses the ni_labpc driver for the common support code shared
      by the ISA, PCI, and PCMCIA boards.
      
      The ISA specific support, and the optional ISA DMA support, are currently
      still in the common ni_labpc driver. The ISA specific code is protected
      by #if IS_ENABLED(CONFIG_COMEDI_NI_LABPC_ISA) and the ISA DMA support
      is protected by #ifdef CONFIG_ISA_DMA_API. This allows the ISA support
      to be enabled on architectures that support VIRT_TO_BUS and optionally
      enables ISA DMA support if ISA_DMA_API is enabled.
      
      Unfortunately, the ISA DMA code uses virt_to_bus(). This results in
      the build failure for architectures that enable ISA_DMA_API but do not
      have VIRT_TO_BUS.
      
      Add a new member to the private data, dma_addr, to hold the phys_addr_t
      returned by virt_to_bus() and initialize it in the ISA specific
      labpc_attach().
      
      For architectures that enable ISA_DMA_API but not VIRT_TO_BUS, this
      will fix the build error. This is also safe for architectures the
      enable both options but don't enable COMEDI_NI_LABPC_ISA because the
      dma channel (devpriv->dma_chan) is only initialized in the ISA
      specific labpc_attach().
