e1b8c62f9a o Introduce efimd_va2pa() to translate addresses in efi_copy{in|out}()
and efi_readin(). This removes MD code from copy.c.

unresolved symbols in loader.sym. This avoids silently creating a

9048fc74e0 Remove the dependency on the Intel EFI headers in sys/boot/efi. Instead
use <machine/efi.h> for the necessary definitions. This makes the EFI

such, maintenance and porting (to IA-32) of the EFI code is made as easy
as possible.

e8e2b20db9 o Support the REL32LSB relocation. It's in the ELF file from which
we construct the EFI image. It doesn't seem to actually end up
   in the EFI image, AFAICT.
o  Replace .quad, .long and .short with data8, data4 and data2 resp.
   The former are gnuisms.
o  Redefine _start_plabel as a data16 with @iplt(_start) as its
   value. This is the preferred way to create user PLT entries.

8b3a02d853 Fix the creation of EFI images that got broken by the import of
binutils 2.15. The linker now creates a .rela.dyn section for
dynamic relocations, while our script created a .rela section.
Likewise, we copied the .rela section to the EFI image, but not
the .rela.dyn section. The fix is to rename .rela to .rela.dyn
in the linker script so that all relocations end up in the same
section again. This we copy into the EFI image.

108e5926e2 Don't hardcode unit 0 for the current device if we're loaded from an
EFI file system. When booting from a CD and there's already an EFI
system partition on the disk, setting the current device to unit 0
will select the harddisk. This invariably breaks installing FreeBSD
when other operating systems have been installed before.

We obviously want to do the same when we're booting over the network.
Maybe later.

fb5fbfc750 Enable the i386 loader to load and run an amd64 kernel. If this puts
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.

389e4c3a2a Remove special casing for running in the simulator from the kernel
and instead add platform, firmware and EFI stubs to the loader.
The net effect of this change is that besides a special console and
disk driver, the kernel has no knowledge of the simulator. This has
the following advantages:
o  Simulator support is much harder to break,
o  It's easier to make use of more feature complete simulators.
   This would only need a change in the simulator specific loader,
o  Running SMP kernels within the simulator. Note that ski at this
   time does not simulate IPIs, so there's no way to start APs.

The platform, firmware and EFI stubs describe the following hardware:
o  4 CPU Itanium,
o  128 MB RAM within the 4GB address space,
o  64 MB RAM above the 4GB address space.

NOTE: The stubs in the skiloader describe a machine that should in
parts be defined by the simulator. Things like processor interrupt
block and AP wakeup vector cannot be choosen at random because they
require interpretation by the simulator. Currently the simulator is
ignorant of this.

This change introduces an unofficial SSC call SSC_SAL_SET_VECTORS
which is ignored by the simulator.

Tested with: ski (version 0.943 for linux)

61e39e41d0 Add command `hcdp'. This command dumps the DIG64 HCDP table if one
exists.
2002-12-18 08:13:03 +00:00
marcel
9050c80f1d Pass the HCDP table address to the kernel. If no such table exists,
NULL is passed. The address of the HCDP table can be found by
iterating over the configuration tables in the EFI system table.
To avoid more duplication, a function can be called with the GUID
of interest. The function will do the scanning. Use the function
in all places where we iterate over the configuration tables in
an attempt to find a specific one.

Bump the loader version number as the result of this.

2b58aefd52 Change the startup code to fix a memory leak and to allow us to
accept load options (=command line options).

The call graph changes from *entry*->efi_main->efi_init, where
efi_main is the EFI equivalent of main to *entry*->efi_main->main,
where main is what you'd expect. efi_main now is what efi_init was.
The prototype of main follows that of C. The first argument is argc
and the second is argv. There is no third argument.
Allocation of heap pages is now handled by the EFI library and it
now deallocates the pages when main() returns or when exit() is
called. This allows us to safely return to the boot manager (or
EFI shell) without leaks. EFI applications are responsible to free
all memory themselves.

Handling of the load options is a bit tricky. There are either no
load options, load options in ASCII or load options in Unicode.
The EFI library will translate the ASCII options to Unicode options
as to simplify user code. Since the load options are passed as a
single string (if present) and main() accepts argc and argv, the
startup code also has to split the string into words and build the
argv vector. Here the trickiness starts. When the loader is started
from the EFI shell, argv[0] will automaticly load the program name.
In all other cases (ie through the boot manager), this is not the
case. Unfortunately, there's no trivial way to check. Hence, a
set of conditions is checked to determine if we need to fill in
argv[0] ourselves or not. This checking is not perfect. There are
known cases where it fails to do the right thing. The logic works
for most expected cases, though. This includes the case where no
options are given.

b6c9fbe053 The boot manager sets the watchdog timer to 5 minutes before invoking
a boot option. When the timer expires the machine is rebooted.
Disable the watchdog timer for 2 reasons:
o  We're an interactive program. We cannot guarantee that we've
   booted the kernel in the time available to us. There have been
   situations where netbooting the right kernel took 2 tries and
   more time than given. Not to speak of the normal behaviour to
   have the loader sitting at the prompt while the user is off
   doing other things (such as figuring out what to type next ;-)
o  We may not boot a kernel at all. We may exit as the result of
   the user typing quit (assuming it took less than 5 minutes to
   type it :-). It is documented that loaders should have disabled
   the watchdog timer if they return to the boot manager. Not doing
   so would cause a reboot while in the boot manager. This appears
   to be harmless, besides of course the actual reboot.

99d4b2d8ed Remove a left-over virtual mapping of uncached I/O port space.
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.
