This introduces InterruptController and HardwareTimer classes to
handle the SoC specific implementations of timers and ints for
the ARM platform.
These could be improved and moved to a more 'generic' level once
we're confident they are 'good enough'.
NOTE: The OMAP timer implementation is fully untested and probably
completely non-functional....
If we find an FDT (either from uImage or otherwise) we make sure
we map it after mmu_init() and use kernel_args to pass it to the
kernel (so it is available at all times there).
This isn't really a bus_manager yet, but just minimal support so
we can get rid of hardcoded ARM SoC support from the core kernel
code.
Needs lots of work, like proper handling of #address-cells and
the like. Also, generic attribute handling, device_manager
integration, and I could go on for hours ;)
Recent linux behaviour (and also copied by BSD) is to preprocess
DTS files with the C preprpocessor to enable sharing constants between
driver implementation and DTS content for more readability.
- Draw conditional breakpoints in a different color from regular
ones for easy visual differentiation.
- Right clicking on an existing breakpoint marker now brings up the
condition editing window.
- Ask the architecture for a stack trace directly, as we only
need the top frame.
- Properly update thread state before we go into condition
evaluation. Otherwise, other parts of the debugger potentially
wouldn't notice that we had continued execution in the case
where the condition evaluates to false, and would indicate a
program stop at the breakpoint erroneously.
* On UEFI, pages are allocated top-down; previously,
VM would fail to allocate early pages due to
running into pages allocated at the top and
assume it had run out of pages to map.

* Use Unicode block drawing characters to provide sub-character accuracy
* Also display the download progress percentage as a number
When downloading big packages this helps seeing that the bar continues
moving and that the download is not stalled.
ThreadHandler:
- When a breakpoint event is hit, we now check if there is an
associated UserBreakpoint with a condition attached. If so,
we schedule an evaluation request, and only stop the thread if
that one evaluates to true (or if evaluation fails in some way).
This implements #9713.
General:
- Add message codes for requesting breakpoint configuration.
UserInterfaceListener/TeamDebugger:
- Add/implement hooks for requesting breakpoint condition changes.
BreakpointsView:
- Add button to request editing the currently selected breakpoint's
condition.
TeamWindow:
- Handle request to show breakpoint edit window.
BreakpointEditWindow:
- Implement simple radio-based UI for modifying the current breakpoint's
condition.
Still missing: Actually handling/evaluating the breakpoint conditions in
the ThreadHandler when the breakpoint is hit.
In order to automate the complete bootstrap build process we need a
mechanism to control the second phase which builds the final packages
on the booted bootstrap Haiku. To avoid additional dependencies
(buildbot slave, ssh, rsh,...) we'd have to cross-build, there's now a
pair of simple python scripts that allows executing commands on a remote
machine. The server script (bootstrap_daemon.py) is added to the
bootstrap image and started automatically during the boot.
CLanguageExpressionEvaluator:
- Add tokenizer handling for operators . and ->.
- Rework _ParseIdentifier() to work recursively if it sees a deref
operator immediately following the current token. This allows
one to refer to the value of structure/class members in an
expression.
* UI still needs some tweaking
* The Services tab has a list of services. This currently include DNS
and will soon also include the services listed in xinetd.
* The DNS tab allows to manage DNS servers (settings can't be saved yet)
- If the current frame belongs to a class function, and the requested name
doesn't match that of any of the parameters/local variables, attempt to
find it in the member list as well.
* Partly reverting hrev47655, as the moved declarations are expected
by many ports to be accessable via string.h.
Following standards is a good thing in general, but not if it causes
more problems than it helps ...
It previously shared the same generated MBR header with bin/writembr,
but they have incompatible needs. The intel partitioning add-on only
wants the MBR code, while writembr wants the whole sector.
Build the desired version of the MBR separately for each target instead
of sharing a single header.
The compile flags were set so that only the boot code itself would be
produced, excluding the (dummy) partition table and signature. The code
in writembr still assumed that the MBR would be 512 bytes however and
therefore access the data array out of bounds.
Fix flags to produce the full 512 byte MBR sector and add a
STATIC_ASSERT so that the size assumption is checked on compilation.
Also fix a typo in mbr.nasm, mostly to trigger re-generation of the
MBR data that one would otherwise need to remove manually...
The two out of bounds array accesses were pointed out by CID 1249923 and
CID 1249924, the insufficiently large target buffer of the memcpy by
CID 1249901.
General:
- Resolving variable values requires both a stack frame and a CPU state.
Adjust all interfaces and callers accordingly.
ExpressionEvaluationJob:
- Pass additional parameters needed for variable value resolution.
- If variable resolution is desired, ExpressionEvaluationJob now
creates a temporary ValueNodeManager for that purpose.
- If the expression parser returns a value node pointer that needs
to be resolved, schedule a corresponding job and wait.
CLanguageExpressionEvaluator:
- Clean up some leftovers that were preventing variable names from being
handled properly in some cases.
- Implement handling of identifier names. These are now looked up against
the value node graph of the active node manager, and if found, corresponding
values are retrieved. If the value has not yet been resolved, an exception
is thrown to ask that to be done.
This gets value resolution working for basic local variables and function
parameters, and consequently, #9712. Structure/class members and/or pointer
indirection aren't yet handled.
With packagefs potentially opening quite a few packages the default of
256 slots is a bit tight. It's 4096 now, which should be safe for a
while, but we might want to consider resizing the table dynamically and
probably even switching to another algorithm for allocating the slots.
Should fix#11328.
