Previously, the bootloader would only provide a single memory range. At least on VirtualBox, this memory range includes the ACPI tables, which the kernel then happily overwrites when executing VM. Much of the infrastructure to use a fullblown memory map is already in place; this patch adds the last (and strangely missing) bit of generating the memory map in a multiboot-compatible way. It should be noted that both the bootloader and the kernel actually violate the multiboot specification by not packing the structure for the memory ranges. This is a NetBSD bug, but it is also a nonissue for (our) practical purposes. It can be fixed without changing the code added in this patch. Change-Id: I7c0a307a8a8133239531e1d2b80f376849f90247 |
