396b74228e kernel/x86_64: save fpu state at interrupts
The kernel is allowed to use fpu anywhere so we must make sure that
user state is not clobbered by saving fpu state at interrupt entry.
There is no need to do that in case of system calls since all fpu
data registers are caller saved.

We do not need, though, to save the whole fpu state at task swich
(again, thanks to calling convention). Only status and control
registers are preserved. This patch actually adds xmm0-15 register
to clobber list of task swich code, but the only reason of that is
to make sure that nothing bad happens inside the function that
executes that task swich. Inspection of the generated code shows
that no xmm registers are actually saved.

b41f281071 boot/x86_64: enable sse early
Enable SSE as a part of the "preparation of the environment to run any
C or C++ code" in the entry points of stage2 bootloader.

SSE2 is going to be used by memset() and memcpy().

f2f91078bd kernel/x86_64: remove memset and memcpy from commpage
There is absolutely no reason for these functions to be in commpage,
they don't do anything that involves the kernel in any way.

Additionaly, this patch rewrites memset and memcpy to C++, current
implementation is quite simple (though it may perform surprisingly
well when dealing with large buffers on cpus with ermsb). Better
versions are coming soon.

6156a508ad kernel/x86[_64]: remove get_optimized_functions from cpu modules
The possibility to specify custom memcpy and memset implementations
in cpu modules is currently unused and there is generally no point
in such feature.

There are only 2 x86 vendors that really matter and there isn't
very big difference in performance of the generic optmized versions
of these funcions across different models. Even if we wanted different
versions of memset and memcpy depending on the processor model or
features much better solution would be to use STT_GNU_IFUNC and save
one indirect call.

Long story short, we don't really benefit in any way from
get_optimized_functions and the feature it implements and it only adds
unnecessary complexity to the code.

eea45d0a32 ARM: cleanup of bootloader memory mapping
* Removes default mapping of a portion of the RAM (will be done
  as needed)
* Passes on the page directory area to kernel, so on early vm init
  the kernel can use the area for pagetable allocation.
* Leaves it to the platform to pass in physical memory range(s). This
  will ultimately come from FDT.
* Fix long standing issue with allocation of the heap, potentially
  causing other part of the bootloader to overwrite the heap.
* Implements pagetable allocator in kernel for early vm mapping.

This fixes the first PANIC seen, we now just get the same one later
on when the VM is up... more to come...

6048591e9d Revert "Added check to ensure KDL does not include frames beyond kernel entry in the backtrace. This prevents KDL from faulting when printing backtrace on ARM."
This reverts commit 3fbb24680c.

As I mentioned in #11131, this fix is not correct, and works around
the problem. The real reason was that arch_debug_call_with_fault_handler
was not working properly, so the fault handler went crazy.

With commit eb92810 that is fixed so this can be reverted.

87e8603d9f Merge branch 'gcc_syslibs'
* From now on, the gcc-specific system libraries (libgcc, libsupc++ and
  libstdc++) are provided by separate packages built along with gcc:
  - gcc_syslibs contains the shared libraries (libgcc_s.so, libsupc++.so and
    libstdc++.so)
  - gcc_syslibs_devel contains the static libraries and both c++ and gcc
    headers
  The shared libraries now make proper use of symbol versioning and there
  are version-specific symlinks
* The buildsystem has been adjusted to no longer use the libraries and
  headers from the cross-compiler, but use the ones provided by the
  above-mentioned packages. The only exception is that the 32-bit libraries
  required for the bootloader of the x86_64 architecture are still taken
  from the cross-compiler.

8f5130edfa package kit: Actually add support for B_HPKG_COMPRESSION_NONE
Until now we always declared in the HPKG header that the package file is
zlib compressed. For uncompressed files we would just store all
individual chunks uncompressed. Now we handle completely uncompressed
files slightly differently: We don't write the redundant chunk size
table anymore. The size savings are minor, but it makes the uncompressed
format read-streamable which may be handy.

When an ARMv7 CPU is detected, immediately turn on the FPU. This allows
us to use vsnprintf in the TRACE call in that function, as our libc is

is not available.

This lets the boot go further, and crash in mmu_init. Next steps:
* Find why mmu_init is crashing
* Setup some fault handlers, otherwise we call uboot ones, and they are
not very helpful. They will also probably not work once the mmu is

44c0c4d3d0 runtime_loader: add support for ELF based TLS
This patch introduces support of ELF based TLS handling with lazy allocation
and initalization of TLS block for each DSO and thread. The implementation
generally follows the official ABI except that generation counter in dtv
is in fact a pointer to Generation object that contains both generation
counter and size of the dtv. That simplified the implementation a bit, but
could be changed later. The ABI requirements regariding in memory position
of TLS block is not honoured what results in static TLS model being
unsupported. However, that should not be a problem as long as
"executables" in Haiku are in fact shared objects and optimizations which
require specific TLS block in memory layout are not possible anyway.

5c0f8450ac Boot loader: Add support for choosing an old packages state
For potential boot volumes with older packages states the respective
item in the boot volume menu now has a sub menu for selecting a state.
The boot loader functionality for this feature is complete -- i.e. the
respective kernel is loaded and the name of the old state is added to
the kernel args -- but kernel packagefs and package daemon support is
still missing.

ebd3bcdb9b exfat: handle 4-byte UTF-16 surrogate pairs
... in filenames. Replace the existing Unicode conversion functions
with UTF conversion functions from js that he relicensed MIT for us.

Put the UTF conversion functions in a private but shared code location
so that they can be accessed throughout the kernel.

Right now we only provide functions to convert between UTF-8 and UTF-16.
At some point we should also add functions to convert between UTF-8 and
UTF-32 and UTF-16 and UTF-32 but these aren't needed by exfat.

Remove the old Unicode conversion functions from exfat as they assumed
UCS-2 characters and don't work with UTF-16 used by exfat.

Rename most variables with the term length with code unit where code units
are intended. The term length, when used, means length in bytes while code
units represent either a full 2-byte UTF-16 character or half a 4-byte
surrogate pair.

2feaa37f24 Move media plug-in support to application side.
The media server tried to use node monitoring to dynamically add and
remove plug-ins, but it isn't that useful:
* When a plug-in is added, applications would have to query the media
server to get an up to date list of available formats. For example
MediaConvert populates its format menus on startup.
* When removing a plugin, if an app already had it loaded, there is not
much that can be done to keep it working.
* The list of plugins was not sorted by directories (user vs system
add-ons), so the directories were re-scanned to make sure user add-ons
were returned first, rendering the node monitoring less interesting.

Now, the format handling is done by each application. The node
monitoring is removed, instead the apps will scan the plugin directory
when first using the media kit classes. Restarting the application is
needed to update the media formats list.

b167307526 kernel: Properly synchronize suspending new thread
After load_image() the child thread is suspended and the parent is
expected to resume it later. However, it is possible that the parent
attempts to resume its child after it has been notified that the image
had been loaded but before the child managed to suspend itself. In such
case the child would suspends itself after that wake up attempt and,
consequently will not be ever resumed.

To mitigate that problem flag Thread::going_to_suspend has been added
which helps synchronizing thread suspension and continuation in a similar
way that "traditional" thread blocking is performed. This means that
the child should behave in a following manner: set its going_to_suspend flag,
notify the parent (i.e. any thread that may want to resume it), acquire
its scheduler_lock and suspend itself if the going_to_suspend flag is set.
The parent should follow pattern: clear going_to_suspend flag of the thread
that is about to be resumed, acquire that thread scheduler_lock and enqueue
it in a run queue if it is suspended.

Thanks Oliver for reporting the bug and identifying what causes it.

a2634874ed scheduler: Estimate the load thread is able to produce
Previous implementation based on the actual load of each core and share
each thread has in that load turned up to be very problematic when
balancing load on very heavily loaded systems (i.e. more threads
consuming all available CPU time than there is logical CPUs).

The new approach is to estimate how much load would a thread produce
if it had all CPU time only for itself. Summing such load estimations
of each thread assigned to a given core we get a rank that contains
much more information than just simple actual core load.
