microblaze: remove consistent_sync and consistent_sync_page

2018-07-20T12:29:54Z

Both unused. Signed-off-by: Christoph Hellwig Signed-off-by: Michal Simek

microblaze: use generic dma_noncoherent_ops

2018-07-20T12:29:47Z

Switch to the generic noncoherent direct mapping implementation. This removes the direction-based optimizations in sync_{single,sg}_for_{cpu,device} which were marked untestested and do not match the usually very well tested {un,}map_{single,sg} implementations.

microblaze: Fix mmap for cache coherent memory

2014-12-17T11:59:59Z

When running in non-cache coherent configuration the memory that was allocated with dma_alloc_coherent() has a custom mapping and so there is no 1-to-1 relationship between the kernel virtual address and the PFN. This means that virt_to_pfn() will not work correctly for those addresses and the default mmap implementation in the form of dma_common_mmap() will map some random, but not the requested, memory area. Fix this by providing a custom mmap implementation that looks up the PFN from the page table rather than using virt_to_pfn. Signed-off-by: Lars-Peter Clausen Signed-off-by: Michal Simek

microblaze: Use asm-generic/io.h

2014-04-07T12:25:53Z

Using generic io.h will narrow down code duplication in architecture io.h. - define PCI_IOBASE - remove non existing pci_io_base extern Signed-off-by: Michal Simek

mm/arch: use __free_reserved_page() to simplify the code

2013-11-13T03:09:03Z

Use __free_reserved_page() to simplify the code in arch. It used split_page() in consistent_alloc()/__dma_alloc_coherent()/dma_alloc_coherent(), so page->_count == 1, and we can free it safely. __free_reserved_page() ClearPageReserved() init_page_count() // it won't change the value __free_page() Signed-off-by: Xishi Qiu Cc: James Hogan Cc: Michal Simek Cc: Benjamin Herrenschmidt Cc: Paul Mackerras Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

microblaze: Do not use module.h in files which are not modules

2013-02-12T10:24:45Z

Based on the patch: "lib: reduce the use of module.h wherever possible" (sha1: 8bc3bcc93a2b4e47d5d410146f6546bca6171663) fix all microblaze files which are not modules. Signed-off-by: Michal Simek

microblaze: Fix coding style issues

Fix coding style issues reported by checkpatch.pl. Signed-off-by: Michal Simek

microblaze: Fix sparse warning - consistent_alloc function

2011-03-09T07:09:58Z

Warning in dma.c was caused by incorrect type in consistent_alloc function. Warning log: CHECK arch/microblaze/kernel/dma.c arch/microblaze/kernel/dma.c:53:26: warning: incorrect type in argument 1 (different base types) arch/microblaze/kernel/dma.c:53:26: expected int [signed] gfp arch/microblaze/kernel/dma.c:53:26: got restricted unsigned int [usertype] flag Signed-off-by: Michal Simek

microblaze: Fix consistent-sync code

2010-05-06T09:22:00Z

PCI_DMA_FROMDEVICE should call invalidation not flushing. Signed-off-by: Michal Simek

microblaze: Fix consistent code

2010-05-06T09:21:59Z

This patch fix consistent code which had problems with consistent_free function. I am not sure if we need to call flush_tlb_all after it but it keeps tlbs synced. I added noMMU and MMU version together. Uncached shadow feature is not tested. Signed-off-by: Michal Simek
