whole loader from a floppy or CD-ROM and execute it as usual - and it
even seem to work, yaay :)
For now, the length of the boot loader is hard-coded, but it is compatible
with the "makeflop" command, i.e. it stores the length in bytes 3 & 4 in
the file.
Also, the maximum head number is currently hard-coded to floppies - ToDo
comments are in the text which insist on fixing this.
This makes testing the boot loader under Linux much easier, as it isn't
able to write to BFS volumes directly (and the copy_to_bfs_image command
doesn't build under Linux).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8606 a95241bf-73f2-0310-859d-f6bbb57e9c96
It now accepts strings of any size, reduced the stack consumption.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8559 a95241bf-73f2-0310-859d-f6bbb57e9c96
addresses and their sizes are now set correctly in image_info as well, as
well as the device/node fields.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8556 a95241bf-73f2-0310-859d-f6bbb57e9c96
reusing the standard libroot objects, but build them all again to make
sure they are compiled with the proper flags (i.e. -fno-pic).
That saves a lot of headaches: as a side effect, the kernel runs fine
again, and even the node monitor test works nicely now. Go figure.
Only the string functions remain separate, but that should be changed
as well one day (it's not problematic, right now).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8545 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added empty implementations of fork() and all the exec*() variants; the
latter currently all call execve() and may pass the correct parameters
(not tested).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8339 a95241bf-73f2-0310-859d-f6bbb57e9c96
is not in a good shape, Linux code is pretty ugly - we'll see which one
we'll choose :)
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8324 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added more global variables that are maintained by the BeOS startup code.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8314 a95241bf-73f2-0310-859d-f6bbb57e9c96
apps are using those.
Their implementation is currently not complete; they just call the
public functions, the group argument is ignored.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8277 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added comments from storage/NodeMonitor.cpp to the syscalls here (they
will be removed from NodeMonitor.cpp), and adapted them where necessary.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8237 a95241bf-73f2-0310-859d-f6bbb57e9c96
that you can now also look up symbols in there.
load_kernel_add_on() now sets the text section read-only & execute after
having loaded the area - note, it currently doesn't have any effect anyway :)
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8173 a95241bf-73f2-0310-859d-f6bbb57e9c96
there is no boot device available - this will prevent modules from getting
lost.
Added a comment to open_module_list() about its limitations while booting.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8170 a95241bf-73f2-0310-859d-f6bbb57e9c96
recognizes this and doesn't enable paging after entering the protected
mode again).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8135 a95241bf-73f2-0310-859d-f6bbb57e9c96
run_menu() now supports menu_item_hook for CHOICE_MENU submenu items.
Now selects the video mode chosen in the menu - it's broken right now
if you enter the boot menu without asking for it (i.e. when there is
no boot volume found).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8116 a95241bf-73f2-0310-859d-f6bbb57e9c96
Calls platform_init_video() directly after the heap initialization - the
logo will now be shown before the VFS is initialized.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8112 a95241bf-73f2-0310-859d-f6bbb57e9c96
scroll bar at the right side that shows you where you are.
"Page Up/Down" now jump one visible page up and down.
Support for MENU_ITEM_NO_CHOICE type.
Constants are now real constants :)
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8110 a95241bf-73f2-0310-859d-f6bbb57e9c96
part of the boot loader (because then the heap is already working).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8107 a95241bf-73f2-0310-859d-f6bbb57e9c96
It's fixed now; mount_file_systems() will just ignore the boot partition.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8105 a95241bf-73f2-0310-859d-f6bbb57e9c96
You can already use the menu, but your options currently don't have any effect.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8094 a95241bf-73f2-0310-859d-f6bbb57e9c96
(when there is one), if you press escape, it will boot in console mode.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8052 a95241bf-73f2-0310-859d-f6bbb57e9c96
Replaced its functionality by a new platform_boot_options() call.
The switch to the logo screen now comes a little later.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8049 a95241bf-73f2-0310-859d-f6bbb57e9c96
above p_filesz - that means it didn't clear BSS etc. - this was not noticeable
from Bochs, though.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8045 a95241bf-73f2-0310-859d-f6bbb57e9c96
write the contents directly into the buffer. If we'll ever intend to
store mode infos in kernel memory, this should be changed back.
vesa_set_mode() now sets the correct flags to get a linear frame buffer;
graphical boot now works in Bochs 2.1.1 as well.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8044 a95241bf-73f2-0310-859d-f6bbb57e9c96
address directly, and therefore, we don't have to copy the structure
and eventually relocate the pointers.
Made the boot logo location dependent on its size.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8042 a95241bf-73f2-0310-859d-f6bbb57e9c96
- began to integrate the SMP/CPU stuff from the old boot loader; currently
disabled, though
- began VESA/VGA support
- added temporary boot splash screen; it's a bit of a hack and only seem
to work in Bochs 2.0.2 for now... (but hey, it looks good ;-))
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8016 a95241bf-73f2-0310-859d-f6bbb57e9c96
the real kernel file system (as there is no amiga_ffs add-on yet).
The file systems now also return the module name of their kernel counterparts.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7995 a95241bf-73f2-0310-859d-f6bbb57e9c96
It will now load all modules only once by identifying them using their inode number.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7991 a95241bf-73f2-0310-859d-f6bbb57e9c96
it's not known (it currently only support the current version, of course :-).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7989 a95241bf-73f2-0310-859d-f6bbb57e9c96
Relocated the fortunes file to better match the usual Be locations.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7980 a95241bf-73f2-0310-859d-f6bbb57e9c96
It now sets the background color correctly in all modes (in hi/true color
currently only if its a gray/black/white color).
Renamed VFS syscalls to the new style.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7978 a95241bf-73f2-0310-859d-f6bbb57e9c96
Improved returned types.
Added and initializes Disk Device Manager.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7972 a95241bf-73f2-0310-859d-f6bbb57e9c96
Fixed read/write calls to use and update the descriptor position.
Removed the CHECK_USER_ADDR() macro; it's now using the usual (more readable) check.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7967 a95241bf-73f2-0310-859d-f6bbb57e9c96
Removed KFileDiskDevice functionality for now (since it would have required more changes).
Also disabled actual partition publishing/unpublishing, because this will
be done differently.
This change will temporarily break the DiskDeviceManagerTest build.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7914 a95241bf-73f2-0310-859d-f6bbb57e9c96
Changed thread_atkernel_exit() to look less broken - the way and when it's
called should still be investigated: NewOS looks a lot cleaner here.
create_thread() now creates the kernel stack upfront, so that it can easily
bail out of that fails. The user stack creation now makes use of B_BASE_ADDRESS
and is therefore a lot better and simpler. In case user stack creation failed,
it should now be able to handle that a lot more gracefully - but that hasn't
been tested yet...
Some cleanup.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7897 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now correctly ignores "." and ".." in a directory.
Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7895 a95241bf-73f2-0310-859d-f6bbb57e9c96
Introduced RESERVED_REGION_ID definition.
Some minor cleanups.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7886 a95241bf-73f2-0310-859d-f6bbb57e9c96
stack - it just fails now (since create_area() currently panics when it
fails, this is a cosmetic change anyway :-)).
Now correctly cleans up in case elf_load_user_image() fails.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7883 a95241bf-73f2-0310-859d-f6bbb57e9c96
Replaced "addr" with "addr_t".
Header cleanups.
There is no need to call set_tls_context() in arch_thread_init_tls().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7880 a95241bf-73f2-0310-859d-f6bbb57e9c96
load_kernel_add_on() now protects the text area read-only (theoretically,
as set_area_protection() has not yet been implemented).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7879 a95241bf-73f2-0310-859d-f6bbb57e9c96
and (very) temporary extension, anyway).
- Fixed _user_create_area() - it will now also recognize B_ANY_KERNEL_BLOCK_AREA,
and it will not access a kernel address for B_EXACT_ADDRESS.
- create_area() will now handle B_EXACT_ADDRESS correctly as well.
- get_memory_map() will now silently ignore the missing final entry if the map
contains only one entry.
- The check for user memory was wrong in get_memory_map(); it worked, but it
was not necessarily portable.
- vm_reserve_address_range() was not correctly initializing the region.
- find_and_insert_region_slot() will now search for reserved regions when
B_EXACT_ADDRESS is used - not yet tested, though.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7871 a95241bf-73f2-0310-859d-f6bbb57e9c96
created a call around find_and_insert_region_slot() that takes care of
everything. Fixed B_BASE_ADDRESS support (it now really works).
First shot at a new VM function vm_reserve_address_range() that will be
used to fix our ELF loader issues (which needs to create adjacent regions
which the VM cannot guaranty at this point).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7870 a95241bf-73f2-0310-859d-f6bbb57e9c96
thread exit - get_death_stack() now returns the interrupt state so that
it can be restored correctly later.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7865 a95241bf-73f2-0310-859d-f6bbb57e9c96
The stack of the main thread is now called "{team name}_main_stack" instead
of primary stack.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7863 a95241bf-73f2-0310-859d-f6bbb57e9c96
a note that we should evaluate the LIBRARY_PATH env variable.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7861 a95241bf-73f2-0310-859d-f6bbb57e9c96
correctly when it entered the next recursion of vnode_path_to_vnode().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7854 a95241bf-73f2-0310-859d-f6bbb57e9c96
Replaced "addr" with "addr_t".
Made segment naming safe (could the buffer could overflow).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7852 a95241bf-73f2-0310-859d-f6bbb57e9c96

Userland segments are now called _seg0rw/_seg0ro.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7851 a95241bf-73f2-0310-859d-f6bbb57e9c96
device with BFS - if it succeeds, it will print out the contents of the
volume's root directory.
fs_mount() now makes the mount structure available when mount() from the
FS is called - so that new_vnode() and get_vnode() can work.
fs_mount() did not correctly clean up when something went wrong; it also
didn't notice if the mount's recursive lock couldn't be created.
Some minor debug output improvements.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7845 a95241bf-73f2-0310-859d-f6bbb57e9c96
it's (almost) read only.
Added it to the build - libvm.a is now build as merged object file, since
the cache functions didn't get exported else.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7831 a95241bf-73f2-0310-859d-f6bbb57e9c96
something went wrong) - this would have hidden circular dependencies
as well.
Recursive directory scan was broken, it didn't filter "." and ".." out.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7829 a95241bf-73f2-0310-859d-f6bbb57e9c96
eventually specified length parameter.
The IOCPARM_LEN() macro should be used by the device/file system
implementation only if applicable.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7828 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7698 a95241bf-73f2-0310-859d-f6bbb57e9c96

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7695 a95241bf-73f2-0310-859d-f6bbb57e9c96
find_real_mem_size must not be called with interrupts turned off.

this out.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7570 a95241bf-73f2-0310-859d-f6bbb57e9c96
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".
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7522 a95241bf-73f2-0310-859d-f6bbb57e9c96

Renamed the user syscalls to the new style.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7521 a95241bf-73f2-0310-859d-f6bbb57e9c96
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
