This enables generation of exceptions that are due to uncorrected
hardware errors. The exception handlers were already in place and will
now actually trigger kernel panics.
Note that this is the simplest form of MCE "handling" and does not add
anything of the broader machine check architecture (MCA) that also allow
reporting of corrected errors. As MCEs are generally hard to decode due
to their hardware specifity, this merely makes such problems more
obvious.
Might help to discern hardware issues in cases that would otherwise just
triple fault and cause a reboot.

The BGradient class is a bit strange as it can store any gradient on its
own, butonly the subclasses allow to set some of the fields.
In the asignment operator, the non-base data (which is in an union) was
not copied over.
More importantly, the missing copy constructor led to the default
implementation being used, and BList (used for the color stops) was
being copied using its default copy constructor, resulting in the two
BGradient (original and copy) poinitng to the same stops data. Heap
corruption resulted whenever one of them was deleted.
Having a working copy ocnstructor fixes this. The alternative is making
the copy constructor private or protected to make sure gradients are not
copied, since normally you'd copy only the subclasses, preserving the
C++ type. However there is nothing enforcing that, and manipulating a
BGradient copied from a subclass works just fine.

- libicule and libiculx do not exist anymore in newer ICU versions
(harfbuzz replaces them), but we didn't actually use them, so remove
them from the build feature and from the package dependencies
- Add namespace usage marcos since the newer ICU packages put ICU things
in a namespace, making it easier to have multiple versions of ICU used
side by side.
No functional change intended, but this makes it possible to build the
code with either ICU 57 (for gcc2) or 66 (for other architectures).
It allows an application to signal that it no longer needs the data in
the given address range and the underlying pages can be discarded and
reused elsewhere. This is finer grained than working with full areas
or mappings at a time and enables unmapping sections of partially used
mappings without giving up its address space.
Compared with punching holes into a mapping by "mapping over" with
PROT_NONE and MAP_NORESERVE, this has the obvious advantage of not
producing a lot of unused extra areas and saves the corresponding
resources. It is also a lot "lighter" of an operation than cutting
existing areas.
This introduces madvise() alongside the existing posix_madvise() to
allow for OS specific extensions. The constants for both functions are
aliased, the POSIX_MADV_* being a subset of the MADV_* ones without the
non-POSIX extensions. Internally posix_madvise() simply calls madvise().
MADV_FREE is commonly supported in other OSes with various subtle
semantic differences as to when pages are actually freed/cleared and how
or whether the pages are counted against the memory use of a process.
In the variant implemented here, pages are always immediately discarded
and memory counting is not altered. This behaviour should be considered
an implementation detail and may be altered later. The actual unmap and
discard could for example be delayed until pages are needed elsewhere to
reduce overhead in case of repeated discarding and remapping.
Note that MADV_FREE doesn't really align with the rest of the madvise()
API as it works like a command (i.e. discard these pages) and does not
add an attribute to the pages in the given range (i.e. mark these pages
for quick access from now on). As such, an MADV_FREE does not need to be
undone by setting a different advice later on, unlike how the other
flags work. This discrepancy may be the reason why it is not part of
POSIX.

This reverts parts of hrev52546 that removed the B_KERNEL_AREA
protection flag and replaced it with an address space comparison.
Checking for areas in the kernel address space inside a user address
space does not work, as areas can only ever belong to one address space.
This rendered these checks ineffective and allowed to unmap, delete or
resize kernel managed areas from their respective userland teams.
That protection was meant to be applied to the team user data area which
was introduced to reduce the kernel to userland overhead by directly
sharing some data between the two. It was intended to be set up in such
a manner that this is safe on the kernel side and the B_KERNEL_AREA flag
was introduced specifically for this purpose.
Incidentally the actual application of the B_KERNEL_AREA flag on the
team user data area was apparently forgotten in the original commit.
The absence of that protection allowed applications to induce KDLs by
modifying the user area and generating a signal for example.
This change restores the B_KERNEL_AREA flag and also applies it to the
team user data area.

The memory map may be unordered and include overlapping ranges. To make

anything unusable from these ranges again.
To calculate the amount of unusable memory, count the total after the
first pass and then subtract the total after the second. This way, only
unusable ranges that actually overlap physical memory (and therefore
reduce the amount of usable memory) get excluded.
Note that the explicit ignore of the ACPI reclaim memory is subsumed by
the above. We still don't want to add this region to the usable memory
map, as that would allow the kernel to allocate pages into that region,
possibly corrupting ACPI tables before they were used. We also don't

So all we need to do is increment the lock's count here,

On the other hand, if we did not find our structure in the lock,
that means we own the lock; so to return with an error from here
without changing the count would result in a deadlock, as the lock

Additionally, take care of part of the case where we have woken up

BeOS didn't support transparent views. As documented in the Be Book,
SetViewColor(B_TRANSPARENT_COLOR) only effect is to not fill the
invalidated areas with the view color before calling Draw() (it avoids
flickering, especially when combined with B_FULL_UPDATE_ON_RESIZE).
A previous change made B_TRANSPARENT_COLOR actually make the view
transparent (that is, additionally to the above, the underlying view is
drawn before the transparent children), but it creates compatibility
issues.
In order to keep the API compatible with BeOS, the new behavior is now
enabled explicitly using the B_TRANSPARENT_VIEW flag. This also opens
for future developments like allowing a view color with an alpha
channel (not supported yet).
Adjust programs that require transparent views.

Scroll bars should look and work identically to before on
HaikuControlLook.
Add DrawScrollBarButton() and DrawScrollBarThumb() and
DrawScrollBarBorder() methods. These methods are used to draw scroll
bars in a generic way so that they can be drawn differently by alternative
control look's (e.g. BeControlLook). Also it gives us back drawing of
scroll bar knobs. However the knob setting is not exposed in the
interface in this commit.
These methods are in addition to the 2 existing DrawScrollBarBackground()
methods that draw the scroll bar background. One draws the area above and
below the thumb and the other is called by the first to actually draw the
area.
The rest of the drawing besides the backgrounds was being done in
BScrollBar before. To draw the scroll bar arrows and thumb we were recyling
other ControlLook methods, while this worked well enough on HaikuControlLook
it wasn't flexible enough for alternative control looks.
DrawScrollBarButton() is used to draw the four scroll buttons and is
typically (so far) used in combination with DrawArrowShape().
DrawScrollBarThumb() draws the scroll bar thumb.
DrawScrollBarBorder() draws a 1px border around the entire scroll bar,
potentially B_KEYBOARD_NAVIGATION_COLOR if focused (although this is
feature not currently used.)
Draw unscrollable scroll bars as if they were disabled including the
buttons with their arrow shapes, background, and thumb.

This is too early (see #15263, media_addon_server crash), and should only happen
after the buffer is recycled. This can be resolved by abusing the fFlags field of
BBuffer to mark the buffer for deletion, and mark the buffer to be reclaimed.
Some BBuffers don't reside in the SharedBufferList, so we have to mark them as to
be reclaimed. For those in the SharedBufferList, call a new RemoveBuffer(), which
can check whether the buffer is still to be reclaimed. For reclaimed BBuffers,
delete them right away, others can be marked for deletion.

This issue was initially detected by PVS Studio (issue number V547) and fixed
as part of Google Code-in 2019.
The initial problem was the calculate_cpu_conversion_factor function
which had been copied in the BIOS and EFI versions of the boot code.
Further investigation led to more duplicated or very similar functions
being identified.
Introduce an arch_cpu.h for the x86 boot platform to group these things
in a single place, and adjust the BIOS and EFI code to call into that.
Note that the BIOS and EFI code is still a little platform specific,
ideally there should be a boot_arch_cpu_init() function for each
architecture as already done for openfirmware and u-boot.
Also remove some irrelevant comments from copypasted files for other
architectures, as that was filling my git grep with useless noise.

LVDS panels must really be driven at their native resolution, otherwise

On my G45 laptop, this allows me to use non-native resolutions on the

connected, I do get a valid display on the internal panel (using the VGA
resolution). VGA still gets "out of range", so we're still not setting

though I've changed some to use shifts to make clear
which bits are allocated are which are unused.)
Sparcv9 runs Openboot in 64 bit mode, which means the cell size is
64bit. Use intptr_t where appropriate to make the open firmware calls
work.
Beware, some values are still 32bit, this matters for example for
of_getprop, if you get 32bits into a 64bit variables it will be in the
MSB of it (big endian only weakness...) and confuse things. See for
example in console.cpp, where the input and output handles are retrieved
as 32bit values. It seems wise to check the expected size when using
of_getprop in these cases, instead of just checking for errors.

Without this, even installed packages still get an "Install" button.
Fixes#14821.
This was implemented by adding BPackageRoster::IsPackageActive. I decided to
have this take a location since GetActivePackages also did, but as noted in my
TODO comment, I think this is awkward.
It would also be nice to show the user they have a different version of a
particular package, but that would require some changes to IsPackageActive.

Consider this scenario:
* A userland thread puts its ID into some structure so that it
can be woken up later, sets its wait_status to initiate the
begin of the wait, and then calls _user_block_thread.
* A second thread finishes whatever task the first thread
intended to wait for, reads the ID almost immediately
after it was written, and calls _user_unblock_thread.
* _user_unblock_thread was called so soon that the first
thread is not yet blocked on the _user_block_thread block,
but is instead blocked on e.g. the thread's main mutex.
* The first thread's thread_block() call returns B_OK.
As in this example it was inside mutex_lock, it thinks
that it now owns the mutex.
* But it doesn't own the mutex, and so (until yesterday)
all sorts of mayhem and then a random crash occurs, or
(after yesterday) an assert-failure is tripped that
the thread does not own the mutex it expected to.
The above scenario is not a hypothetical, but is in fact the
exact scenario behind the strange panics in #15211.
The solution is to only have _user_unblock_thread actually
unblock threads that were blocked by _user_block_thread,
so I've introduced a new BLOCK_TYPE to differentiate these.
While I'm at it, remove the BLOCK_TYPE_USER_BASE, which was
never used (and now never will be.) If we want to differentiate
different consumers of _user_block_thread for debugging
purposes, we should use the currently-unused "object"
argument to thread_block, instead of cluttering the
relatively-clean block type debugging code with special
types.
One final note: The race condition which was the case of
this bug does not, in fact, imply a deadlock on the part
of the rw_lock here. The wait_status is protected by the
thread's mutex, which is acquired by both _user_block_thread
and _user_unblock_thread, and so if _user_unblock_thread
succeeds faster than _user_block_thread can initiate
the block, it will just see that wait_status is already
<= 0 and return immediately.
Fixes#15211.
* It's safe to assume that if the file is shorter than
the provided header, things will go poorly.
* Avoids a random vauge ReadBuffer error.
* This doesn't fix#15230, but makes the issue clearer.

Before this commit, *all* ConditionVariable operations (yes, all;
even Wait, Notify, etc.) went through a single spinlock, that also
protected the sConditionVariableHash. This obviously does not scale
so well with core count, to say the least!
With this commit, we add spinlocks to each Variable and Entry.
This makes locking somewhat more complicated (and nuanced; see
inline comment), but the trade-off seems completely worth it:
(compile HaikuDepot in VMware, 2 cores)
before
real 1m20.219s
user 1m5.619s
sys 0m40.724s
after
real 1m12.667s
user 0m57.684s
sys 0m37.251s
The more cores there are, the more of an optimization this will
likely prove to be. But 10%-across-the-board is not bad to say
the least.

In CodyCam, we attempt to cast the result of this macro to const char*.
However, the ternary operator has lower priority than the cast so it
doesn't work as expected.
Add some protective parentheses here.

Unless __STRICT_ANSI__ is defined (as it is when running the compiler in
--std=c89 or --std=c99, but not when running it without any specific
args), we can enable these by default and behave like most other
systems. I don't know why no one has done this yet despite suggesting it
multiple times and people prefer to #define _BSD_SOURCE manually
everywhere.
Remove all places in our Jamfiles and sources where it had been defined.
_DEFAULT_SOURCE is now enabled by default for all sources of Haiku, since we
let the compiler use GNU extensions (no strict C standard specified on
command line)
Use _DEFAULT_SOURCE as the define name to match current versions of
glibc. Enable it if _BSD_SOURCE is #defined in compiler flags, for
backward compatibility.

My upcoming changes to use our "futexes" instead of semaphores
will obviously not work on non-Haiku platforms, so we now
need a copy of this class in libbe_build.
This defines the number of bits in a byte and is used in tnftpd.
Once this is merged, some patches to tnftpd can be removed.
