Have the processor defer all faults and exceptions for control

2007-05-27T19:02:47+00:00

speculative loads. This at least makes control speculative loads
work. In the future we should analyze which faults/exceptions
we want to handle rather than defer to avoid having to call the
recovery code when it's not strictly necessary.

Major rework of the ia64 loaders. The two primary objectives are:

2006-11-05T22:03:04+00:00

1. Make libefi portable by removing ia64 specific code and build
   it on i386 and amd64 by default to prevent regressions. These
   changes include fixes and improvements over previous code to
   establish or improve APIs where none existed or when the amount
   of kluging was unacceptably high.
2. Increase the amount of sharing between the efi and ski loaders
   to improve maintainability of the loaders and simplify making
   changes to the loader-kernel handshaking in the future.

The version of the efi and ski loaders are now both changed to 1.2
as user visible improvements and changes have been made.

Redefine a PTE as a 64-bit integral type instead of a struct of

bit-fields. Unify the PTE defines accordingly and update all
uses.

Enable the i386 loader to load and run an amd64 kernel. If this puts

2003-05-01T03:56:30+00:00

things over floppy size limits, I can exclude it for release builds or
something like that.  Most of the changes are to get the load_elf.c file
into a seperate elf32_ or elf64_ namespace so that you can have two
ELF loaders present at once.  Note that for 64 bit kernels, it actually
starts up the kernel already in 64 bit mode with paging enabled.  This
is really easy because we have a known minimum feature set.

Of note is that for amd64, we have to pass in the bios int 15 0xe821
memory map because once in long mode, you absolutely cannot make VM86
calls.  amd64 does not use 'struct bootinfo' at all.  It is a pure loader
metadata startup, just like sparc64 and powerpc.  Much of the
infrastructure to support this was adapted from sparc64.

Remove a left-over virtual mapping of uncached I/O port space.

2002-11-28T03:25:51+00:00

Previous kernels unwantingly depended on this mapping, but as
of version 1.123 of src/sys/ia64/ia64/machdep.c this dependency
has been removed. Consequently, one has to update the kernel
before updating the loader. The documented/recommended upgrade
will suffice in this case.

Due to a visible (from the kernels point of view) change in
behaviour, bump the loader version number from 0.3 to 1.0.

o Fix a size calculation based on a 8KB page, while under EFI

2002-10-24T07:53:12+00:00

   pages are 4KB.
o  As a second order fix, don't assume we have enough space
   after the bootinfo block left in a page to hold the memory
   map.
o  A third order fix as that we removed the assumption that a
   bootinfo block fits in a single 8KB page.

o Remove namespace pollution from param.h:

2002-05-19T04:42:19+00:00

   -  Don't include ia64_cpu.h and cpu.h
   -  Guard definitions by  _NO_NAMESPACE_POLLUTION
   -  Move definition of KERNBASE to vmparam.h

o  Move definitions of IA64_RR_{BASE|MASK} to vmparam.h
o  Move definitions of IA64_PHYS_TO_RR{6|7} to vmparam.h

o  While here, remove some left-over Alpha references.
