yet, though (instead, it directly performs all requests, so there is no
functional difference to the previous mechanism).
devfs and the file cache will directly access the I/O scheduler. There is
one scheduler per raw disk device; devfs detects that automatically, and
all I/O will go through the scheduler, then.

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
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
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
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
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
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
only).
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
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
to deny further port/sem allocation (and also simplifies port/sem stats).
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()).
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
to acquire the team spinlock).
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
the size of the stat structure to allow extensions of that structure.
Renamed those syscalls to the new naming scheme.
Updated the syscalls to support stat extensions.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7494 a95241bf-73f2-0310-859d-f6bbb57e9c96
probably be available as public kernel API as well (or rather, only).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7492 a95241bf-73f2-0310-859d-f6bbb57e9c96
in device_manager.h).
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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7489 a95241bf-73f2-0310-859d-f6bbb57e9c96
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
main, not by getting the module any longer.
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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7425 a95241bf-73f2-0310-859d-f6bbb57e9c96
