swiotlb: add hwdev to swiotlb_phys_to_bus() / swiotlb_sg_to_bus()

2008-12-28T08:54:52Z

Impact: extend functions with a (yet unused) parameter, update callsites Some architectures need it - in preparation for highmem swiotlb. Signed-off-by: Jeremy Fitzhardinge Signed-off-by: Ingo Molnar

swiotlb: add arch hook to force mapping

2008-12-17T17:58:13Z

Impact: generalize the sw-IOTLB range checks Some architectures require special rules to determine whether a range needs mapping or not. This adds a weak function for architectures to override. Signed-off-by: Ian Campbell Signed-off-by: Jeremy Fitzhardinge Signed-off-by: Ingo Molnar

swiotlb: allow architectures to override phys<->bus<->phys conversions

2008-12-17T17:58:09Z

Impact: generalize phys<->bus<->phys conversions in the swiotlb code Architectures may need to override these conversions. Implement a __weak hook point containing the default implementation. Signed-off-by: Ian Campbell Signed-off-by: Jeremy Fitzhardinge Signed-off-by: Ingo Molnar

swiotlb: move some definitions to header

2008-12-16T20:31:40Z

Impact: cleanup Signed-off-by: Ian Campbell Signed-off-by: Jeremy Fitzhardinge Signed-off-by: Ingo Molnar

swiotlb: allow architectures to override swiotlb pool allocation

2008-12-16T20:31:38Z

Impact: generalize swiotlb allocation code Architectures may need to allocate memory specially for use with the swiotlb. Create the weak function swiotlb_alloc_boot() and swiotlb_alloc() defaulting to the current behaviour. Signed-off-by: Jeremy Fitzhardinge Signed-off-by: Ian Campbell Signed-off-by: Ingo Molnar

introduce generic header file for the software IO/TLB

2008-10-16T18:21:28Z

A series of patches introduce a generic header file for the software IO/TLB implementation in lib/swiotlb.c. Currently each architecture using this code defines the prototypes itself. The prototypes are moved to include/linux/swiotlb.h and this file is included in architecture specific code for X86 and IA64. This patch: Create include/linux/swiotlb.h file which contains all function prototypes for the lib/swiotlb.c file. (akpm: the dependent patches will be trickled through arch trees) Signed-off-by: Joerg Roedel Cc: Ingo Molnar Cc: Thomas Gleixner Cc: "Luck, Tony" Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
