Norman Feske	83bdfea9b0	Extend Cpu_session with thread-affinity API ... This patch introduces the functions 'affinity' and 'num_cpus' to the CPU session interface. The interface extension will allow the assignment of individual threads to CPUs. At this point, it is just a stub with no actual platform support.	2012-09-05 10:25:04 +02:00

Norman Feske	288fd4e56e	Add support for allocating DMA memory ... This patch extends the RAM session interface with the ability to allocate DMA buffers. The client specifies the type of RAM dataspace to allocate via the new 'cached' argument of the 'Ram_session::alloc()' function. By default, 'cached' is true, which correponds to the common case and the original behavior. When setting 'cached' to 'false', core takes the precautions needed to register the memory as uncached in the page table of each process that has the dataspace attached. Currently, the support for allocating DMA buffers is implemented for Fiasco.OC only. On x86 platforms, it is generally not needed. But on platforms with more relaxed cache coherence (such as ARM), user-level device drivers should always use uncacheable memory for DMA transactions.	2012-06-20 09:17:48 +02:00
