* dma-mapping: add the device argument to dma_mapping_error()FUJITA Tomonori2008-07-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architecturesAndrea Righi2008-07-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit boundary. For example: u64 val = PAGE_ALIGN(size); always returns a value < 4GB even if size is greater than 4GB. The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for example): #define PAGE_SHIFT 12 #define PAGE_SIZE (_AC(1,UL) << PAGE_SHIFT) #define PAGE_MASK (~(PAGE_SIZE-1)) ... #define PAGE_ALIGN(addr) (((addr)+PAGE_SIZE-1)&PAGE_MASK) The "~" is performed on a 32-bit value, so everything in "and" with PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary. Using the ALIGN() macro seems to be the right way, because it uses typeof(addr) for the mask. Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in include/linux/mm.h.

| * V4L/DVB (8343): soc_camera_platform: Add SoC Camera Platform driverMagnus Damm2008-07-20
| | | | | | | | | | | | | | | | | | | | This patch adds a simple platform camera device. Useful for testing cameras with SoC camera host drivers. Only one single pixel format and resolution combination is supported.

| * V4L/DVB (8342): sh_mobile_ceu_camera: Add SuperH Mobile CEU driver V3Magnus Damm2008-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is V3 of the SuperH Mobile CEU soc_camera driver. The CEU hardware block is configured in a transparent data fetch mode, frames are captured from the attached camera and written to physically contiguous memory buffers provided by the newly added videobuf-dma-contig queue. Tested on sh7722 and sh7723 processors. Changes since V2: - remove SUPERH Kconfig dependency - move sh_mobile_ceu.h to include/media - add board callback support with enable_camera()/disable_camera() - add support for declare_coherent_memory - rework video memory limit - more verbose error messages Changes since V1: - fixed the CEU driver to work with the newly updated patches Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@pengutronix.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
| * V4L/DVB (8341): videobuf: Add physically contiguous queue code V3Magnus Damm2008-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is V3 of the physically contiguous videobuf queues patch. Useful for hardware such as the SuperH Mobile CEU which doesn't support scatter gatter bus mastering. Since it may be difficult to allocate large chunks of physically contiguous memory after some uptime due to fragmentation, this code allocates memory using dma_alloc_coherent(). Architectures supporting dma_declare_coherent_memory() can easily avoid fragmentation issues by using dma_declare_coherent_memory() to force dma_alloc_coherent() to allocate from a certain pre-allocated memory area. Changes since V2 - use dma_handle for physical address - use "scatter gather" instead of "scatter gatter" Changes since V1: - use dev_err() instead of pr_err() - remember size in struct videobuf_dma_contig_memory - keep struct videobuf_dma_contig_memory in .c file - let videobuf_to_dma_contig() return dma_addr_t - implement __videobuf_sync() - return statements, white space and other minor fixes Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@pengutronix.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
