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. In a future change, these segments will be used to service requests with special constraints, such as "usable for 16-bits DMA" or "must be part of the direct physical mapping". * Makefrag.am (libkernel_a_SOURCES): Add vm/vm_page.c. * i386/Makefrag.am (libkernel_a_SOURCES): Add i386/i386at/biosmem.{c,h}. * i386/i386/vm_param.h: Include kern/macros.h. (VM_PAGE_DMA_LIMIT, VM_PAGE_MAX_SEGS, VM_PAGE_DMA32_LIMIT, VM_PAGE_DIRECTMAP_LIMIT, VM_PAGE_HIGHMEM_LIMIT, VM_PAGE_SEG_DMA, VM_PAGE_SEG_DMA32, VM_PAGE_SEG_DIRECTMAP, VM_PAGE_SEG_HIGHMEM): New macros. * i386/i386at/model_dep.c: Include i386at/biosmem.h. (avail_next, avail_remaining): Remove variables. (mem_size_init): Remove function. (i386at_init): Initialize and use the biosmem module for early physical memory management. (pmap_free_pages): Return phys_last_addr instead of avail_remaining. (init_alloc_aligned): Turn into a wrapper for biosmem_bootalloc. (pmap_grab_page): Directly call init_alloc_aligned instead of pmap_next_page. * i386/include/mach/i386/vm_types.h (phys_addr_t): New type. * kern/bootstrap.c (free_bootstrap_pages): New function. (bootstrap_create): Call free_bootstrap_pages instead of vm_page_create. * kern/cpu_number.h (CPU_L1_SIZE): New macro. * kern/slab.h: Include kern/cpu_number.h. (CPU_L1_SIZE): Remove macro, moved to kern/cpu_number.h. * kern/startup.c (setup_main): Change the value of machine_info.memory_size. * linux/dev/glue/glue.h (alloc_contig_mem, free_contig_mem): Update prototypes. * linux/dev/glue/kmem.c (linux_kmem_init): Don't use defunct page queue. * linux/dev/init/main.c (linux_init): Don't free unused memory.

2016-01-23Import the vm_page module from X15 and relicense to GPLv2+Richard Braun
* vm/vm_page.c: New File. * vm/vm_page.h: Merge vm_page.h from X15. (struct vm_page): New members: node, type, seg_index, order, vm_page_header. Turn phys_addr into a phys_addr_t.
2015-05-19kern: import `macros.h' from x15Justus Winter
Import the macro definitions from the x15 kernel project, and replace all similar definitions littered all over the place with it. Importing this file will make importing code from the x15 kernel easier. We are already using the red-black tree implementation and the slab allocator from it, and we will import even more code in the near future. * kern/list.h: Do not define `structof', include `macros.h' instead. * kern/rbtree.h: Likewise. * kern/slab.c: Do not define `ARRAY_SIZE', include `macros.h' instead. * i386/grub/misc.h: Likewise. * i386/i386/xen.h: Do not define `barrier', include `macros.h' instead. * kern/macro_help.h: Delete file.

2014-01-03vm: reduce the size of struct vm_pageJustus Winter
Previously, the bit field left 31 bits unused. By reducing the size of wire_count by one bit, the size of the whole struct is reduced by four bytes. * vm/vm_page.h (struct vm_page): Reduce the size of wire_count to 15 bits.
2014-01-03vm: merge the two bit fields in struct vm_pageJustus Winter
* vm/vm_page.h (struct vm_page): Merge the two bit fields.
2014-01-03vm: remove NS32000-specific padding from struct vm_pageJustus Winter
Apparently, the NS32000 was a 32-bit CPU from the 1990ies. The string "ns32000" appears nowhere else in the source. * vm/vm_page.h (struct vm_page): Remove NS32000-specific padding.

* vm/vm_resident.c (vm_page_external_count): Define variable. (vm_page_grab): New argument `external'. All callers changed. Keep track of number of externally managed pages. Don't let non-privileged threads exceed the externally-managed page limit. (vm_page_grab_contiguous_pages): New argument `external'. All callers changed. Keep track of number of externally managed pages. Don't let non-privileged threads exceed the externally-managed page limit. (vm_page_convert): New argument `external'. All callers changed. (vm_page_release): New argument `external'. All callers changed. Keep track of number of externally managed pages. (vm_page_bootstrap): Initialize M->external. * vm/vm_page.h (vm_page_external_limit, vm_page_external_count): New variables. (struct vm_page): New members `external' and `extcounted'. * vm/vm_pageout.c (vm_pageout): Initialize vm_page_external_limit and vm_page_external_target. (VM_PAGE_EXTERNAL_LIMIT, VM_PAGE_EXTERNAL_TARGET): New macro. (vm_pageout_external_target): New variable. (vm_pageout_scan): Regard "too many externally managed pages" as a reason to keep doing work, but if that's the only reason we're doing work, then the only thing we do is schedule cleaning of pages. Help keep track of the number of externally managed pages that we care about. * vm/vm_pageout.c (VM_PAGEOUT_BURST_WAIT): Reduce to 10ms/page. (VM_PAGEOUT_EMPTY_WAIT): Reduce to 75 ms.
