Implement the todo in Open Target Folder to select the result by sending
Tracker a message with the refs to select.
Add a new kSelect message constant to tracker_private.h to hook into.
Tracker reads in the message and finds the window that the refs are located in,
activates it, then selects the corresponding poses scrolling the pose view
if necessary.
Bump version of Open Target Folder to 1.0.2
Intel changed the PCH interrupt bits between Sandy Bridge and Ivy Bridge
to make space for the 3rd display pipe. Take this into account and check
for the correct bits on the newer devices.
Fixes#11522.
"BToolBar" matches the current convention ("BStatusBar", "BMenuBar", etc.)
I've no idea what I was thinking when I renamed this before...
Also adjust all users of BToolBar (Tracker and ShowImage).
* The default notifier didn't always take the setting into account.
* The mail server was not using the setting from the settings file and
instead waiting for a message that wasn't sent anywhere.
Fixes#10852.
* Use the preferred time source (GetTimeSource) for the node
* Fix node releasing when creating the connection fails
* Add virtual slots and padding
* Refactor _Connect method
* offsetof is not allowed on non-POD types so we need to use
offset_of_member (gcc2 accepts offsetof, and C++11 relaxed the
constraints on where it is allowed so it should work there too)
* we have offset_of_member as a workaround until we switch to C++11,
move it from khash (which is soon to be removed) to list.h which is the
other place where it is used (for this one single call in our whole
codebase)
Also fix a typo in vfs.cpp.
* Not everything compiles; all protocols, and inbound filters do, though.
* Renamed a few classes to give a better idea what they are for; prefixed
public classes with the 'B' prefix.
* Moved ProtocolConfigView's classes into the BPrivate namespace.
* Moved BMailFilter into its own file.
* Added BMailFilter::DescriptiveName(). This is now used by the RuleFilter
in order to give a description of what it's doing (ie. no more dozens of
"Rule filter" entries in the preferences).
* Removed no longer used MailAddon.h.
* Renamed Addon to AddOn where found, since that is more consistent with the
rest of the API.
* Merged the former MailProtocol with the former MailProtocolThread; the
differentiation between those two was pretty messy.
* All configuration views touched so far are now using the layout kit.
* The RuleFilter is currently broken functionality wise; I have not yet decided
how to solve the stuff it uses (TriggerFileMove() does not exist anymore,
for example).
* BMailAddOnSettings (formerly known as AddonSettings) now directly subclass
BMessage; there are no Settings() and EditSettings() method anymore. The
class uses a copy of itself to determine whether or not it has been changed.
* Lots of cleanup.
* Renamed imap_config.cpp to ConfigView.cpp, IMAPFolderConfig.(h|cpp)
to FolderConfigWindow.(h|cpp).
* Got the latter to build.
* Added Settings class to simplify and unify the BMessage based
settings access.
* Removed the InboundProtocol[Thread] implementation from the build for now.
I already made this patch in Heidi's clone of BToolbar. Adding it here
allows me to drop Heidi's version altogether.
I also relicensed the header file at the permission of Stephan. The .cpp

CreateThreadEvent::DoDPC() missed a reference release to balance the
acquired reference before queuing the DPC, resulting in the
CreateThreadEvent objects being leaked.
This also removes the destructor that tried to cancel the DPC. Since
the class is reference counted and only destroyed when the DPC has
run and released the last reference, this didn't make much sense.
The signal to the team/thread is only actually sent in a deferred
procedure. To ensure that the team/thread stays valid between the DPC
being queued and it actually running, we need to acquire a reference.
Fixes#11390, where the DPC was run after the team was already
destroyed.
* VMArea::AddWaiterIfWired(): Replace the ignoreRange argument by a
flags argument and introduce (currently only) flag
IGNORE_WRITE_WIRED_RANGES. If specified, ranges wired for writing
are ignored. Ignoring just a single specified range doesn't cut it
in vm_soft_fault(), and there aren't any other users of that feature.
* vm_soft_fault(): When having to unmap a page of a lower cache, this
page cannot be wired for writing. So we can safely ignore all
writed-wired ranges, instead of just our own. We even have to do that
in case there's another thread that concurrently tries to write-wire
the same page, since otherwise we'd deadlock waiting for each other.
The thread that is being [un]scheduled already has its time_lock locked
in {stop|continue}_cpu_timers(). When updating the TeamTimeUserTimer,
the team is asked for its cpu time. Team::CPUTime() then iterates the
threads of the team and locks the time_lock of the thread again.
This workaround passes a possibly locked thread through the relevant
functions so Team::CPUTime() can decide whether or not a thread it
iterates needs to be locked or not.
This works around #11032 and its duplicates #11314 and #11344.
when uninitializing a partition or a disk (removing the partition
table), check that all partitions from that table are unmounted, as they

Fixes#8827.
The BOOT_GDT_SEGMENT_COUNT was based on USER_DATA_SEGMENT on both
x86 and x86_64. However, on x86_64 the order of the segments is
different, leading to a too small gBootGDT array. Move the define to
the arch specific headers so they can be setup correctly in either case.
Also add a STATIC_ASSERT() to check that the descriptors fit into the
array.

There were 3 setting files, each an archived BMessage. Now there is only
one with all the data inside.
* Rework the SettingsPane class to save and load settings from a
message, rather than having each panel pick a file path on its own
* Move saving the app filters to the preference app, rather than the
server (so it's done at the same place as other settings)
* Rework loading prefs in the server so the settings message is read
from the file once and all settings are loaded from it.
This turns out to be more changes than I anticipated.
Fixes#9424.
* Move relevant parts up into BFormat so other format classes can use
those
* Adjust BDurationFormat and BTimeUnitFormat for the changes
* Remove the "default" date format, it is better to keep only a default
locale and let applications create B*Formats from it as needed.
* Creating a B*Format without arguments to the constructor now
configures it for the default locale, which allows for easy use in
standard cases (formatting something with the current language and
format)
* Creating a B*Format is potentially an expansive operation, it is
advised to keep the instance around and reuse it whenever possible.
However it must be "refreshed" when the locale changes, for apps which
supports that, since it keeps a copy of the language and formatting
convention, rather than a pointer to the locale as it did before.
* BDate setters don't perform any validation, use with caution.
* BCalendarView setters do perform validation checks, and will adjust
the day so it fits the requested month or year.
* Add tests for the BCalendarView setters.
* There is a little code duplication. This will be moved to BFormat once
the time and datetime formatting is also moved out of BLocale
* The way to create a BDateFormat from a BLocale is still open for
discussion. I'm undecided between making BDateFormat a member of
BLocale, or adding a BDateFormat(const BLocale&) constructor.
* Adjust all users of the API.
A BGeolocation object can query an online service to get geolocation
and geotagging data:
* LocateSelf() tries to locate the machine it is running on, by using an
online database of wifi access points
* Locate() (not yet implemented) searches a BString and converts it to
lat/lon coordinates (reverse geotagging)
* Name() (not yet implemented) finds a suitable name for the given
coordinates (address, building name, or anything fitting).
The default service used is openbmap.org, which is freely available but
not very accurate. A request has been sent to Mozilla to use MLS
(Mozilla Location Services), which is a bit more accurate but needs an
API key. MLS is used for geolocation on FirefoxOS, for mobile phones
which don't have a GPS, and the data can be contributed by Firefox for
Android or the dedicated MozStumbler app.
Alternatively, Google Maps also provide the service, but wants
people to pay for it. Google Maps data is more accurate as all Android
devices contribute data to it.
All 3 services use the same JSON-based API: we send a list of reachable
Wifi APs (mac address and signal strength), and we get lattitude and
longitude information, and possibly extra data which will currently be
unused.
This can be used to implement HTML5 geolocation with reasonably accurate
results, but it can also be used in other places. For example
FirstBootPrompt could try to guess a list of most likely languages and
keyboard layouts from it (if wifi is working at install time, that is).
Comments to #9672 agree that there's really no need to
expose the dev_t handle, thus simplifying the API.
The dev_t handle, if required, can be retrieved via
BPartition::GetVolume() instead.
This patch adds user_access() which can be used to gracefully handle
page faults that may happen when accessing user memory. It is used
by arch_cpu_user{memcpy, memset, strlcpy}() to allow using optimized
functions from the standard library.
Currently only x64 uses this, but nothing really is arch specific here.

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.

There is absolutely no reason for these functions to be in commpage,
they don't do anything that involves the kernel in any way.

implementation is quite simple (though it may perform surprisingly
well when dealing with large buffers on cpus with ermsb). Better

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.

* 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...
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.
If GCC knows what these functions are actually doing the resulting
code can be optimized better what is especially noticeable in case of
invocations of atomic_{or,and}() that ignore the result. Obviously,
everything is inlined what also improves performance.

Based on an earlier piece of source code of mine that parsed JSON into
QObjects, this JSON parser creates a BMessage tree.
Will be used by Stephan in HaikuDepot for communication with the web app.
* 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.
* The new libstdc++.so contains program headers of type PT_RELRO (for
making segments read-only after relocation). While the actual feature
has not been implemented, the runtime_loader should now silently
accept (and ignore) those program headers.
instead or additionally to string.h, in preparation for functions move.
* moves str[n]casecmp() functions and others to strings.h.
* strings.h doesn't include string.h anymore.
* this solves #10949
Besides that this is a nicer interface, it allows us to get a the HPKG
header as a side effect of initializing the reader, thus preventing
seeking backward in the file. This makes "package recompress - <file>"
work.
* Prefix lock functions with __ to mark them as private. Add
forwarding macros to keep existing code working.
* Avoids symbol name clashes with kernel lock APIs, occuring when
using kernellandemu-lib in userlandfs. Thanks to Ingo for the
suggestion.
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.
* PackageFileHeap{Reader,Writer} as well as Package{Reader,Writer} and
their implementation and super classes do now internally use a
BPositionIO instead of a FD to access the package file. This provides
more flexibility needed for features to come.
* BPackageReader has already grown a new Init() version with a
BPositionIO* parameter.
Simple BPositionIO implementation using the POSIX API on a FD. In effect
similar to BFile, but more easily ported to kernel and boot loader (and
the FD is reusable).
* Ingo copied the methods into a shared location, and then obviously
"forgot" to let BFS use them. As a side note for Ingo: the complete
error GCC reported was "std::fssh_size_t" not defined with the macro
wrapper as code location. The actual problem was a "using std::size_t"
in some C++ header that accidentally got included after the wrapper.
* The shared Query code is not yet used. That'll be done another time.
* Renamed BFS_SHELL define to FS_SHELL, such that QueryParserUtils can be
used in any file system shell, not just the bfs_shell.
* BCompressionAlgorithm is a base class for classes that provide
compression/decompression functionality. There are methods for
compressing/decompressing a single buffer and factory methods for
a compressing/decompressing input/output BDataIO.
* BZlibCompressionAlgorithm is a BCompressionAlgorithm implementation
using zlib.
* FDDataWriter and ZlibDataWriter weren't used anymore.
* AbstractDataWriter was implemented only by PackageFileHeapWriter,
which was only used by WriterImplBase.
* Add a PackageFileHeapWriter::AddDataThrows() which has semantics
equivalent to the previously inherited WriteDataThrows().
Can be requested/stopped via BPackageRoster::{Start,Stop}Watching().
The notification message has the what code B_PACKAGE_UPDATE and contains
fields "event", "location", and "change count".
* The Install() and Update() versions that take a const char* array
now check whether a string looks like a path to a local package file.
If so, they use that file instead of interpreting the string as a
search string.
* Extend the repository hierarchy. There's now a LocalRepository base
class from which InstalledRepository and the new MiscLocalRepository
derive. The latter is instantiated once and collects all package files
specified by path.
* BFatalErrorException: Add commitTransactionResult property and
respective constructor. In case committing the transaction failed,
BPackageManager throws a BFatalErrorException with the result.
* BFatalErrorException::UserInteractionHandler: Pass
BCommitTransactionResult to ProgressTransactionCommitted().
* BDaemonClient: Move inner class BCommitTransactionResult to top level
and make it public.
* BCommitTransactionResult:
- Add a whole bunch of specific error code enum values. Such an error
code is now the primary error, as opposed to before where we would
mix status_t and enum value errors. There's a systemError property
of type status_t which may provide additional information, though
(depending on the primary error type).
- Remove the errorMessage property. Due to mapping all errors to the
specific error codes this is no longer necessary. Mixing such a
message with another error description is also not very helpful when
it comes to localization (still not supported, though).
- Add several properties (paths, strings, error codes) that serve as
arguments to the primary error and are used by FullErrorMessage().
- Add issues property, a list of instances of new class
BTransactionIssue. Those describe non-critical issues (e.g. failed
update of a settings file) that occurred in the process of
committing the transaction. Those issues should be presented to the
user by the package management program.
* Exception: Adjust to transport the BCommitTransactionResult
properties.
* CommitTransactionHandler, FsTransactions, Root, Volume: Adjust to
BCommitTransactionResult/Exception changes.
* CommitTransactionHandler: Now requires a BCommitTransactionResult to
which it adds the issues it encounters. The reply BMessage is no
longer needed, though.
* Volume: Refactor common code from the three methods that use
CommitTransactionHandler into new method _CommitTransaction.
Add GetPathOrName() and PathOrName() methods which try to get some kind
of usable path or at least a file name for the entry. Useful mainly for
debugging and error reporting cases.
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
compiled with floating point support and will trigger a fault if the FPU
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
enabledvery helpful. They will also probably not work once the mmu is
enabledvery helpful. They will also probably not work once the mmu is
enabled...
* The Network Kit now makes use of it for BUrlContext, so we need this
in the public headers.
* Problem caught by the new build bot by compiling the unit tests.
* These aren't tested, but since we go off of DCE
versions for a lot of stuff, they may work.
* AMD doens't include market names in their drivers
anymore, so if we want to label them it will take
additional work.
This patch makes it possible to inline rdmsr and wrmsr instruction. The
performance impact shouldn't be significant since they are used relatively
rarely and wrmsr is usually a serializing instruction, but there is no reason
not to do so.
The goal of this patch is to amortize the cost of context switch by making
the compiler aware that context switch clobbers all registers. Because all
register need to be saved anyway there is no additional cost of using
callee saved register in the function that does the context switch.
Similarly to previous patch regarding GDT this is mostly a rewrite of
IDT handling code from C to C++. Thanks to constexpr IDT is now entirely
generated at compile-time.
Virtually no functional change, just rewriting the code from
"C in *.cpp files" to C++. Use of constexpr may be advantageous but
that code is not performance critical anyway.
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.
* Instead of forcing the hash-table to use a copy of the key,
introduce and use TypeOperation template to avoid taking a
reference of a reference type (which gcc2 doesn't allow).
* PackageFSVolumeInfo: Add the directories for all relevant states.
* PackageFSPackageInfo: Include the package file's parent directory node
ref.
Package daemon and package kit still don't support old states yet.
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.
... 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.
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.
...when sending the whole view state over the link.
Also inherit the fill rule when pushing states (DrawState
copy constructor). A somewhat sloppy oversight, I must add.
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.
Most of the actual UserEvent work is done in DPC so that we don't have

* ... instead of queuing it for the job thread. The advantage is that
the request will be handled immediately and clients won't have to wait
for transactions (which may even require user feedback) to finish. It
complicates Volume a bit, since there are now two threads that may

protected by a lock.
* For commit transaction requests check whether another package request
is already pending/in progress before queuing a job. Fail immediately,
if there is.

Everything untested, but compiles, so it must work. The idea is to introduce
BAffineTransform additionally to the existing Origin and Scale properties of
BViews. One may use it in parallel or as an alternative. Painter in app_server
is not yet aware of the additional transformation. It is however already used
to transform drawing coordinates. It probably needs to work differently,
perhaps only in Painter and AGGTextRenderer.

When switching AppMetaMimeCreator from BMimeType to Database the

SOLVER_DISTUPGRADE mode.
* BPackageManager: Add FullSync() using the new solver mode.
* pkgman: Add full-sync command.
The new command is similar to the update command without arguments, just
more aggressive, allowing downgrading or even removal of packages, to
match the state of the repositories. Just like "update" it doesn't work

UserEvent can be fired from scheduler_reschedule() i.e. while holding current

one of its timers sends a signel to it, then scheduler_enqueue_in_run_queue()

There was also a minor issue with both scheduler_reschedule() and
scheduler_enqueue_in_run_queue() acquiring current CPU scheduler mode lock.

Adjust Database{Location} to only attempt to create a mimetype when

* The BIOS video mode sometimes reports a scaled mode instead of the
physical panel dimensions. Get the data from the VBT table as well, and
use it if the reported resolution is bigger.
* On first boot, force the panel native mode so the user doesn't have to
set it manually.
* Only allow a single head at a time on i855gm, as the card can't drive
both heads at the same time.
* Detect when a new requested mode is the same as the current one, and
skip modesetting in that case. Avoids screen flickering when changing
workspaces.
* Fix some cases of misdetecting which pipes to enable
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.
* Previously PE binaries would trigger the "incorrectly
executable" dialog. Now we get a special message for
B_LEGACY_EXECUTABLE and B_UNKNOWN_EXECUTABLE
* Legacy at the moment is a R3 x86 PE binary. This could
be extended to gcc2 binaries someday far, far, down the
road though
* The check for legacy is based on a PE flag I see
set on every R3 binary (that isn't set on dos ones)
* Unknown is something we know *is* an executable, but
can't do anything with (such as an MSDOS or Windows
application)
* No performance drops as we do the PE scan last
* Tested on x86 and x86_gcc2
This field forces kernel to track each CPU load all the time. It is not
a problem with the current scheduler on a multicore systems, but on
single core machnies or with any other future scheduler this field may
become just an unnecessary burden. It isn't difficult for an application
to compute CPU load by itself when it needs it.
The icon is meant as an addition to or replacement of the label. Icon
bitmaps for various states of the control (off, on, partially on, each
enabled or disabled, plus up to 125 custom states) can be set
individually via SetIconBitmap() (getter IconBitmap()).
The convenience method SetIcon() can be used to set the bitmaps for the
standard states from a single bitmap; it also supports cropping the
icon to its non-transparent area. Code borrowed from BIconButton.
atomic_{get, set}64() are problematic on architectures without 64 bit
compare and swap.
Also, using sequential lock instead of atomic access ensures that
any reads from cpu_ent::active_time won't require any writes to shared
memory.
The client code is not supposed to change the topology info.
It would be also nice if cpu_topology_node::children was an array of
pointers to const but that would require several const_casts in the
topology tree generation code so it's probably not worth it.
Apparently, reading from dr3 is slower than reading from memory
with cache hit.
Also, depending on hypervisor configuration, accessing dr3 may cause
a VM exit (and, at least on kvm, it does), what makes it much slower
than a memory access even when there is a cache miss.
Add get_safemode_option_early() and get_safemode_boolean_early() to get
safemode options before the kernel heap has been initialized. They use a
simplified parser.
* VMTranslationMap:
- Add DebugPrintMappingInfo(): Given a virtual address it is supposed
to print the paging structure information for that address. To be
implemented by derived classes.
- Add DebugGetReverseMappingInfo(): Given a physical addresss it is
supposed to find all virtual addresses mapped to it. To be
implemented by derived classes.
* X86VMTranslationMapPAE: Implement the new methods
DebugPrintMappingInfo() and DebugGetReverseMappingInfo().
* Add KDL command "mapping". It supports both virtual address lookups
and reverse lookups.
__flatten_process_args() does now have the executable path as an
additional (optional) parameter. If specified, the function will read
the file's SYS:ENV attribute (if set) and use its value to modified the
environment it is preparing for the new process. Currently supported
attribute values are strings consisting of "<var>=<value>" substrings
separated by "\0" (backslash zero), with '\' being used as an escape
character. The environment will be altered to contain the specified
"<var>=<value>" elements, replacing a preexisting <var> element (if
any).
A possible use case would be setting a SYS:ENV attribute with value
"DISABLE_ASLR=1" on an executable that needs ASLR disabled.
* VMAddressSpace: Add randomizingEnabled property.
* VMUserAddressSpace: Randomize addresses only when randomizingEnabled
property is set.
* create_team_arg(): Check, if the team's environment contains
"DISABLE_ASLR=1". Set the team's address space property
randomizingEnabled accordingly in load_image_internal() and
exec_team().
* Create new interface for cpuidle modules (similar to the cpufreq
interface)
* Generic cpuidle module is no longer needed
* Fix and update Intel C-State module
