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
Christian Prochaska	7a369bc74d	Add an 'executable' flag to 'Rm_session::attach()' ... With this patch clients of the RM service can state if they want a mapping to be executable or not. This allows dataspaces to be mapped as non-executable on Linux by default and as executable only if needed. Partially fixes #176.	2012-04-20 11:21:19 +02:00
Norman Feske	d6e30c19de	Replace 'Native_capability::copy_to' by accessor ... The 'copy_to' function turned out to be not flexible enough to accommodate the Noux fork mechanism. This patch removes the function, adds an accessor for the capability destination and a compound type 'Native_capability::Raw' to be used wherever plain capability information must be communicated.	2012-03-28 09:58:51 +02:00
