2016-02-22Remove kmem cache flags from the debugging interfaceRichard Braun
* include/mach_debug/slab_info.h (CACHE_FLAGS_NO_CPU_POOL, CACHE_FLAGS_SLAB_EXTERNAL, CACHE_FLAGS_NO_RECLAIM, CACHE_FLAGS_VERIFY, CACHE_FLAGS_DIRECT): Remove macros. * kern/slab.c (host_slab_info): Pass raw cache flags to caller.
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.

2016-02-22Optimize slab lookup on the free pathRichard Braun
Caches that use external slab data but allocate slabs from the direct physical mapping can look up slab data in constant time by associating the slab data directly with the underlying page. * kern/slab.c (kmem_slab_use_tree): Take KMEM_CF_DIRECTMAP into account. (kmem_slab_create): Set page private data if relevant. (kmem_slab_destroy): Clear page private data if relevant.

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.

(kmem_pagealloc, kmem_pagefree, kmem_slab_create, kmem_slab_destroy, kalloc, kfree): Update to use the new pagealloc functions. (kmem_cache_compute_sizes): Update the algorithm used to determine slab size and other cache properties. (kmem_slab_use_tree, kmem_cache_free_to_slab, host_slab_info): Update to correctly use the cache flags.

2016-02-07vm: allocate a large map for all objects larger than SMALL_SIZEJustus Winter
* vm/vm_external.c (vm_external_create): Allocate a large map for all objects larger than SMALL_SIZE. 'vm_external_state_{g,s}et' can deal with offsets larger than 'LARGE_SIZE', so currently objects larger than 'LARGE_SIZE' are missing out on the optimization.
2016-02-07vm: remove unused field from struct vm_externalJustus Winter
* vm/vm_external.h (struct vm_external): Remove unused field 'existence_count'.
2016-02-07Remove kmem mapRichard Braun

2016-02-06Change computation of slab sizeRichard Braun
Allocating directly out of the physical memory allocator makes the slab allocator vulnerable to failures due to fragmentation.

(kmem_cache_compute_sizes): Update the algorithm used to determine slab size and other cache properties.

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.

2016-01-29Fallback on direct PCI access when no BIOS32 is availableSamuel Thibault
Some hardware start shippping with no BIOS32 at all, and we'll have to implement ACPI to get the address of the mmconfig table. In the meanwhile, we can hope that the direct probe works (it does on HP820 for instance). * linux/src/arch/i386/kernel/bios32.c (pcibios_init): Also try check_direct_pci() when bios32 probing failed.
2016-01-23Merge branch 'rbraun/vm_page'Richard Braun
2016-01-23Use vm_page as the physical memory allocatorRichard Braun
This change replaces the historical page allocator with a buddy allocator implemented in vm/vm_page.c. This allocator allows easy contiguous allocations and also manages memory inside segments.
