2016-02-22Fix slab allocator option handlingRichard Braun
The slab allocator has grown to use multiple ways to allocate slabs as well as track them, which got a little messy. One consequence is the breaking of the KMEM_CF_VERIFY option. In order to make the code less confusing, this change expresses all options as explicit cache flags and clearly defines their relationships. The special kmem_slab and vm_map_entry caches are initialized accordingly. * kern/slab.c (KMEM_CF_DIRECTMAP): Rename to ... (KMEM_CF_PHYSMEM): ... this new macro. (KMEM_CF_DIRECT): Restore macro.

2016-02-20Avoid slab allocation failures caused by memory fragmentationRichard Braun
Since the slab allocator has been changed to sit directly on top of the physical allocator, failures caused by fragmentation have been observed, as one could expect. This change makes the slab allocator revert to kernel virtual memory when allocating larger-than-page slabs. This solution is motivated in part to avoid the complexity of other solutions such as page mobility, and also because a microkernel cannot be extended to new arbitrary uncontrolled usage patterns such as a monolithic kernel with loadable modules. As such, large objects are rare, and their use infrequent, which is compatible with the use of kernel virtual memory. * kern/slab.c: Update module description. (KMEM_CF_SLAB_EXTERNAL, KMEM_CF_VERIFY): Update values. (KMEM_CF_DIRECT): Remove macro. (KMEM_CF_DIRECTMAP): New macro.

2016-02-02Stack the slab allocator directly on top of the physical allocatorRichard Braun
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.
