Use PCI macros2016-01-29T19:03:08ZSamuel Thibaultsamuel.thibault@ens-lyon.org2016-01-29T19:03:08Zurn:sha1:0191a6b08f1d0e023994a64079be2d3b764d6232

Fallback on direct PCI access when no BIOS32 is available2016-01-29T18:28:16ZSamuel Thibaultsamuel.thibault@ens-lyon.org2016-01-29T18:28:16Zurn:sha1:b282c5d4fa0a99556d9b977b3a9b92e06c66db85
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 allocator2016-01-23T20:24:25ZRichard Braunrbraun@sceen.net2016-01-23T18:52:24Zurn:sha1:e835160b6b95f3b904fbc429392a63be1e4ed6b8
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".
