* Add kmem_vallocSamuel Thibault2020-05-011-1/+3
| | | | | | | | | | | Functions like vremap need to allocate some virtual addressing space before making their own mapping. kmem_alloc_wired can be used for that but that wastes memory. * vm/vm_kern.c (kmem_valloc): New function. * vm/vm_kern.h (kmem_valloc): New prototype. * linux/dev/glue/kmem.c (vremap): Call kmem_valloc instead of kmem_alloc_wired. Also check that `offset' is aligned on a page.
* linux: Remove incompatible local prototype.Justus Winter2016-10-121-4/+3
| | | | | * linux/dev/glue/kmem.c (vremap): Remove prototype, include the right header instead.
* Use vm_page as the physical memory allocatorRichard Braun2016-01-231-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
