lock_memory() and unlock_memory() will now silently fail and return success -
that's only to get things working.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7754 a95241bf-73f2-0310-859d-f6bbb57e9c96
Also made elf_lookup_symbol_address() less restrictive with respect to the
ELF symbol found (it now accepts all types, not only functions).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7714 a95241bf-73f2-0310-859d-f6bbb57e9c96
tested, though.
No longer copies the elf_header in insert_preloaded_image(); it's not used
at runtime (should be superfluous to keep in other kernel images, too).
dump_symbols() now ignores entries with invalid values - don't know exactly
what makes a good entry, but that should look okay.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7713 a95241bf-73f2-0310-859d-f6bbb57e9c96
standard byte order functions in the kernel).
Small cleanup.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7705 a95241bf-73f2-0310-859d-f6bbb57e9c96
Fixed warnings when compiled with TRACE_ELF.
Changed elf_lookup_symbol_address() to returning more useful information.
It now also scans the extended debug symbol table if present - for now, this
only works with preloaded images except the kernel.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7701 a95241bf-73f2-0310-859d-f6bbb57e9c96
(in BeOS, all kernel areas are r/w).
If you use B_READ_AREA/B_WRITE_AREA flags, you make the area readable
or even writeable from userland!
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7700 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now uses the extended possibilities of the elf_lookup_symbol_address() call.
Fixed a bug in dbg_stack_trace(); it could crash at the top most stack frame.

like any other module (yeeha!).
You can even unload preloaded images later on (to replace them with a
more up-to-date on disk version).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7532 a95241bf-73f2-0310-859d-f6bbb57e9c96
If an image cannot be created out of a preloaded_image, its resources
are freed now.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7531 a95241bf-73f2-0310-859d-f6bbb57e9c96
Also renamed elf_load_kspace() to load_kernel_add_on(), and friends.
The new unload_kernel_add_on() now has an image_id as parameter, no longer
a path (like the former elf_unload_kspace()).
Now requires a driver to export the api_version symbol.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7528 a95241bf-73f2-0310-859d-f6bbb57e9c96
Also renamed elf_load_kspace() to load_kernel_add_on(), and friends.
The new unload_kernel_add_on() now has an image_id as parameter, no longer
a path (like the former elf_unload_kspace()).
Fixed missign file system unload.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7527 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now registers its images as it should do (so you can use commands like
listimage in userland).
Added new debugger command "image".

Renamed the user syscalls to the new style.

freed in the wrong order in case of an error (could have crashed the kernel).
Implemented insert_preloaded_images() which prepares the preloaded images
for later use in the kernel.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7520 a95241bf-73f2-0310-859d-f6bbb57e9c96

Renamed those syscalls to the new naming scheme.
Updated the syscalls to support stat extensions.

Fixed some comments.
Removed realpath() from probe.c for now - mechanism will be changed, and that
prevented it from being built as part of the kernel; it's currently not functional.

be any size, not just full path names (even without the file name...). Optimized
it to only traverse paths that match the prefix.
The built-in modules now honor the prefix as well.
Renamed module_iterator::path_stack to stack.
The system add-on path was even wrong (but that didn't matter yet, as we're
still do a recursive search for modules).
The user add-on path now matches the real one - but that should probably be
retrieved from calling find_directory(), anyway...
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7483 a95241bf-73f2-0310-859d-f6bbb57e9c96
The prefix will obviously ignored currently!
Fixed get_next_loaded_module_name(); it will now work correctly (doesn't check, though,
if the module is currently loaded...).
Removed the module_test() function - doesn't belong here.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7465 a95241bf-73f2-0310-859d-f6bbb57e9c96

It now also creates the root node directly.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7438 a95241bf-73f2-0310-859d-f6bbb57e9c96
team_create_team() now uses the B_NORMAL_PRIORITY constant instead of the number directly.

Renamed vfs_register_filesystem() to vfs_register_file_system().
Changed return codes to status_t where appropriate.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7424 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added all of them - module_loader.c and boot_hack.c won't be needed anymore.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7351 a95241bf-73f2-0310-859d-f6bbb57e9c96
Nothing is tested right now, and it's not yet complete, but it's changed so that
it does compile in our tree (and looks a bit more like the other files, too).

buffered and determined at runtime if not (i.e. via isatty()) - but that
doesn't seem work at this time.
Must revisit later on!
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7340 a95241bf-73f2-0310-859d-f6bbb57e9c96
Removed all old NewOS error codes.
Cleaned up the includes a bit.
Now prints out a list of preloaded images.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7331 a95241bf-73f2-0310-859d-f6bbb57e9c96
Implemented the possibility for built-in modules - they have to be listed
in sBuiltInModules in module.c to be registered automatically.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7318 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added system_info.c to the build.
Added stats support functions to sems & ports.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7290 a95241bf-73f2-0310-859d-f6bbb57e9c96
elf_load_image() now uses this heap for the preloaded_image structures.
Moved gKernelArgs and gKernelEntry to different files.
Improved enabling debug output (it can now be activated by a makefile, too)
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7281 a95241bf-73f2-0310-859d-f6bbb57e9c96
The virtual/physical allocated ranges are now correctly filled in mmu_init_for_kernel(),
and no longer too early.
Now allocates a kernel stack of 8192 bytes.
Added some temporary fillers for the kernel args.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7270 a95241bf-73f2-0310-859d-f6bbb57e9c96
Removed start_kernel() function - it's now replaced by the platform_start_kernel()
call.
Fixed the kernel add-on boot module search path.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7265 a95241bf-73f2-0310-859d-f6bbb57e9c96
start_kernel() now panics, so that we don't run through (since it doesn't
actually jump to the kernel yet).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7256 a95241bf-73f2-0310-859d-f6bbb57e9c96
The heap will now no longer be mapped in kernel space, but will be placed
at a fixed address (0x110000 - former start of free physical memory).
platform_allocate_region() is now implemented and calls mmu_allocate().
mmu_allocate() now supports mapping to a predefined virtual address
to be able to load the kernel correctly (and only for that).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7254 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now, platform_get_boot_partition() will work correctly.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7253 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now prints out a comment if LBA access doesn't work (since CHS access is not yet implemented).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7250 a95241bf-73f2-0310-859d-f6bbb57e9c96
Moved the data section closer to the end of the 1024 bytes of the boot
block - the region before is reused as scratch buffer in the real mode
data segment.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7234 a95241bf-73f2-0310-859d-f6bbb57e9c96
It switches to real mode for execution of the BIOS interrupt; it's really
only intended for the boot loader.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7233 a95241bf-73f2-0310-859d-f6bbb57e9c96
both Bochs and my real computer seem to know it anyway, so it's untested.
The real mode segment descriptors now start at 0x10000, because the code
is loaded there. Added an additional stack segment descriptor to be able
to use a stack below 0x10000.

loader initialization.
This is the start of the zbeos equivalent. It can already be executed
using the BFS boot block, but it cannot yet load itself from a floppy
like the original does.

Incorporated NewOS change 1930: sends the parent SIGCHLD if the team
goes away.
create_thread() now returns B_BAD_TEAM_ID when the team is in death state
instead of ERR_TASK_PROC_DELETED.
Cleaned headers.

Removed team_remove_team_from_hash() as it's no longer necessary.
Also incorporated NewOS change 1930: maintain the parent/children lists.
Cleaned up the headers.

Added some comments.

Took the chance and cleaned it up even more; this change is not a functional change.

was broken because of some new behavior that puts initialized varaibles
in .bss anyway (if you initialize with zero). The bootloader was relying
on not having a .bss. Fixed in the linker script.".
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6968 a95241bf-73f2-0310-859d-f6bbb57e9c96
Saved the port_entry.closed member and now set the capacity to 0, since
it is not used any longer (reduces the size of the port table).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6956 a95241bf-73f2-0310-859d-f6bbb57e9c96
