* Use vm_page as the physical memory allocatorRichard Braun2016-01-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
