* Fallback on direct PCI access when no BIOS32 is availableSamuel Thibault2016-01-291-0/+2
| | | | | | | | | 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.
* Use vm_page as the physical memory allocatorRichard Braun2016-01-234-143/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
