* linux block: allow loading data up to 4GiB limitSamuel Thibault2021-08-281-1/+8
| | | | | | | | | | | | | | Linux drivers are only limited by the DMA32 constraint, not by the directmap constraint. But our segment order is currently set to DMA < DMA32 < DIRECTMAP < HIGHMEM (since that is what we will have in 64bit mode). In PAE mode this makes DMA32 limited to 800MiB. Ideally we'd have DMA < DIRECTMAP < DMA32 < HIGHMEM but that'd make the memory code more complex, and we are to remove the Linux drivers anyway. In the meanwhile, In non-PAE mode we can just use HIGHMEM which is already limited to 4GiB, that will do the work. * linux/dev/glue/block.c (VM_PAGE_LINUX): New macro. (device_read): Use VM_PAGE_LINUX instead of VM_PAGE_DMA32.
* linux block: Fix checking block sector.Samuel Thibault2021-08-271-0/+2
| | | | * linux/dev/glue/block.c (check_rw_block): Return 0 on no error.
* vm_page_grab: allow allocating in high memorySamuel Thibault2021-08-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | vm_page_grab was systematically using the VM_PAGE_SEL_DIRECTMAP selector to play safe with existing code. This adds a flags parameter to let callers of vm_page_grab specify their constraints. Linux drivers need 32bit dmas, Xen drivers use kvtophys to clear some data. Callers of kmem_pagealloc_physmem and vm_page_grab_phys_addr also use kvtophys. Otherwise allocations can go to highmem. This fixes the allocation jam in the directmap segment. * vm/vm_page.h (VM_PAGE_DMA, VM_PAGE_DMA32, VM_PAGE_DIRECTMAP, VM_PAGE_HIGHMEM): New macros. (vm_page_grab): Add flags parameter. * vm/vm_resident.c (vm_page_grab): Choose allocation selector according to flags parameter. (vm_page_convert, vm_page_alloc): Pass VM_PAGE_HIGHMEM to vm_page_grab. (vm_page_grab_phys_addr): Pass VM_PAGE_DIRECTMAP to vm_page_grab. * vm/vm_fault.c (vm_fault_page): Pass VM_PAGE_HIGHMEM to vm_page_grab. * vm/vm_map.c (vm_map_copy_steal_pages): Pass VM_PAGE_HIGHMEM to vm_page_grab. * kern/slab.c (kmem_pagealloc_physmem): Pass VM_PAGE_DIRECTMAP to vm_page_grab. * i386/intel/pmap.c (pmap_page_table_page_alloc): Pass VM_PAGE_DIRECTMAP to vm_page_grab. * xen/block.c (device_read): Pass VM_PAGE_DIRECTMAP to vm_page_grab. * linux/dev/glue/block.c (alloc_buffer): Pass VM_PAGE_DMA32 to vm_page_grab.

| | | | | | | | | | * linux/dev/drivers/block/ahci.c (ahci_do_port_request): Reject sectors beyond LBA48 or LBA28. * linux/dev/glue/block.c (check_rw_block): New function. (rdwr_partial, rdwr_full): Use check_rw_block to reject block number overflows. * linux/src/drivers/block/ide.c (do_rw_disk): Reject sectors beyond LBA28 or CHS.
* 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.

(struct temp_data): Define member `pages' as a struct list. (alloc_buffer): Update to use list_xxx functions. (free_buffer, INIT_DATA, device_open, device_read): Likewise.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of a "page considered external", which apparently takes into account whether a page is dirty or not, redefine this property to reliably mean "is in an external object". This commit mostly deals with the impact of this change on the page allocation interface. * i386/intel/pmap.c (pmap_page_table_page_alloc): Update call to vm_page_grab. * kern/slab.c (kmem_pagealloc_physmem): Use vm_page_grab instead of vm_page_grab_contig.

* Use vm_page as the physical memory allocatorRichard Braun2016-01-232-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
