* Stack the slab allocator directly on top of the physical allocatorRichard Braun2016-02-022-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to increase the amount of memory available for kernel objects, without reducing the amount of memory available for user processes, a new allocation strategy is introduced in this change. Instead of allocating kernel objects out of kernel virtual memory, the slab allocator directly uses the direct mapping of physical memory as its backend. This largely increases the kernel heap, and removes the need for address translation updates. In order to allow this strategy, an assumption made by the interrupt code had to be removed. In addition, kernel stacks are now also allocated directly from the physical allocator. * i386/i386/db_trace.c: Include i386at/model_dep.h (db_i386_reg_value): Update stack check. * i386/i386/locore.S (trap_from_kernel, all_intrs, int_from_intstack): Update interrupt handling. * i386/i386at/model_dep.c: Include kern/macros.h.

* ipc: replace the IPC table with a radix treeJustus Winter2015-05-2015-2814/+189
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the port names are mapped to an IPC object (e.g. a port) using a table. This, however, requires large chunks of continuous memory, and leads to scalability problems as virtual kernel memory is a scarce resource. To avoid excessive overhead, non-contiguous port names are spilled into a splay tree. Replace the IPC table with a radix tree.

* ipc: replace reverse hash table with a radix treeJustus Winter2015-05-206-168/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, there is a hash table mapping (space, object) tuples to `ipc_entry' objects. This hash table is intertwined with the IPC tables. There is one hash table per IPC space, but it is only for the entries in the IPC table. This hash table is called `local' in the source. All IPC entries being spilled into the splay tree are instead mapped by a global hash table. Replace the local (i.e. per IPC space) reverse hash table with a radix tree. * ipc/ipc_entry.c (ipc_entry_grow_table): Adjust accordingly. * ipc/ipc_entry.h (struct ipc_entry): Adjust comment. * ipc/ipc_hash.c: Adjust comment explaining the local lookup table.
