17a3389882 Remove phys_addr_range, just use addr_range for both virtual and physical address ranges (as requested by Ingo). 2012-06-21 19:48:03 +01:00

d8efc6caf6 Changes to kernel_args to make it identical for x86 and x86_64.
* Added a FixedWidthPointer template class which uses 64-bit storage to hold
  a pointer. This is used in place of raw pointers in kernel_args.
* Added __attribute__((packed)) to kernel_args and all structures contained
  within it. This is necessary due to different alignment behaviour for
  32-bit and 64-bit compilation with GCC.
* With these changes, kernel_args will now come out the same size for both
  the x86_64 kernel and the loader, excluding the preloaded_image structure
  which has not yet been changed.
* Tested both an x86 GCC2 and GCC4 build, no problems caused by these changes.

192af9e0af Changed addr_range to use uint64.
I've tested this change on x86, causing no issues. I've checked over the code
for all other platforms and made the necessary changes and to the best of my
knowledge they should also still work, but I haven't actually built and
tested them. Once I've completed the kernel_args changes the other platforms
will need testing.

ff9151d11f Added ignore_physical_memory_ranges_beyond_4gb() which removes the memory
beyond 4 GB from the physical memory ranges.

e5846dfa61 Added shared sort_[physical_]address_ranges() to avoid code duplication. Also
fixes the m68k build.

d73ddac5bf * Introduced phys_addr_range type, an equivalent to addr_range for physical
address ranges, and a set of support functions working with it.
* Changed the type of the kernel_args physical address range arrays to
  phys_addr_range and adjusted the code working with those.
* Removed a bunch of duplicated address range code in the PPC's mmu.cpp.

863c623f9a Added is_address_range_covered(), returning whether the given address range
is fully covered by the ranges in the array.

f795376ec6 remove_addr_range() is actually called remove_address_range().

73a72c42e2 Added get_free_address_range() to get a free range in a given range array.

3e161fb661 * Instead of its home-brewn solution, mmu_init() now uses the functions declared
in addr_range.h to add ranges to the arrays. This fixes the crashing bug reported
  by Larry Baydak.
* Added some more exported functions to kernel_args.cpp (prototypes are in addr_range.h).
* TODO: let the PPC/OpenFirmware implementation use those as well.

53ac60d4ea Added the prototype for insert_address_range() that can be used for the
various addr_range arrays in the kernel_args structure.

ca109e727d Moved the addr_range struct out of kernel_args.h to a separate file.
