Issue #3450
On Fujitsu S936, evaluating the _BIF method on each battery-info update
successively increased the RAM usage, while _BST (dynamic battery
status) and _STA (generic status) did not show this behavior. Therefore
this commit retrieves only dynamic information periodically (resp. on
SCI IRQ). Now, acpica hast static RAM usage in idle state for 24+ hours.
The root cause for the increased RAM usage is still shady. While it
could just be normal that it grows until a certain yet unknown limit,
there may also be memory leak in contrib code or some strange AML on the
designated notebook.
Issue #3454
This mode is used on Linux (if acpi=strict is not set on boot cmdline)
and Windows. The mode ignores certain errors and/or bad AML constructs.
1) Allow "implicit return" of last value in a control method
2) Allow access beyond the end of an operation region
3) Allow access to uninitialized locals/args (auto-init to integer 0)
4) Allow ANY object type to be a source operand for the Store() operator
5) Allow unresolved references (invalid target name) in package objects
6) Enable warning messages for behavior that is not ACPI spec compliant
The labels of clipboard ROM and clipboard report sessions of WM clients
must be consistent with the client's nitpicker label. Hence, we must
route those sessions through the window manager, analogously to the
approach taken for shape reports in #3165.
Issue #3437
- make port able to be prepared repeatedly
Rpcgen refuses to overwrite an already existing header, so try to
always remove it beforehand
- get rid of 'cp' warning 'cp: warning: source file
'src/lib/libc/sys/sys/time.h' specified more than once'
- silence patch message 'patch unexpectedly ends in middle of line'
Fixes#3420.
Move the _vfs_sync implementation from vfs_plugin.h to vfs_plugin.cc and
wrap all VFS access in the VFS_THREAD_SAFE macro.
Syncing must be made thread safe because it often happens when closing
files and may require suspending the current thread for I/O signal
dispatching.

* isatty
For the moment it is not possible to determine if the fd belongs to a
tty. For whatever reasons, the check is done multiple times, e.g.
'tclsh', which will spam the LOG.
* sysctl(HW_FLOATINGPT)
FPU is enabled on all our platforms, so return true.
Fixes#3389.
Start and stop the DHCP state machine as the Nic link-state changes.
Invoke the link state handler during configuration rather than assume
that in the case of a downed link lwIP will defer DHCP until the link
comes up.
Additionally, support static DNS configuration via the "nameserver"
configuration attribute.
Fix#3388
This removes implementations of and also references to anonymous new and
delete operators from the libc implementation. As allocators for
new/delete Libc::Allocator instances are used, which (paradoxically) map
to libc malloc/free.
* Adjust expected pow(-1/1, inf/-inf/nan) output to current libm
behavior (as in FreeBSD, glibc, and OpenLibm) and return 1 on
x86_64/x86_32/arm
* Add 'double float' outputs for ARM which are defined to float
issue #3289
Replace the FreeBSD libm with OpenLibm, which is easier to port.
OpenLibm is used by Mirage's freestanding Ocaml runtime (sin POSIX).

This reverts commit 918b9a9fa4.
The Muen debug console buffer was increased by the recent update, which
alleviates the issue with many log messages as in the ieee754 test.
* Make package buildable for ARM too
* Move usb library to src targets for explicitly named targets
* adapt remaining run-scripts to use the correctly named usb drivers
Ref #2190
This enforces the use of unsigned 64-bit values for time in the duration type,
the timeout framework, the timer session, the userland timer-drivers, and the
alarm framework on all platforms. The commit also adapts the code that uses
these tools accross all basic repositories (base, base-*, os. gems, libports,
ports, dde_*) to use unsigned 64-bit values for time as well as far as this
does not imply profound modifications.
Fixes#3208
As a preparatory step for introducing the new block-client API, we have
to turn the 'Block::Connection' into a class template. The template
argument will be used to tie an application-defined job type to the
block connection.
Issue #3283
This patch removes the blocking Block::Session::sync RPC function and
adds the asynchronous operations SYNC and TRIM to the block session's
packet-stream interface.
Even though the patch adjusts all block components to the interface
change, the components keep the former blocking handling of sync
internally for now because of the design of the 'Block::Driver'
interface. This old interface is not worth changing. We should instead
migrate the block servers step by step to the new
'Block::Request_stream' API.
Fixes#3274
This patch replaces the formerly fixed 2 KiB data alignment within the
packet-stream buffer by a server-defined alignment. This has two
benefits.
First, when using block servers that provide small block sizes like 512
bytes, we avoid fragmenting the packet-stream buffer, which occurs when
aligning 512-byte requests at 2 KiB boundaries. This reduces meta data
costs for the packet-stream allocator and also allows fitting more
requests into the buffer.
Second, block drivers with alignment constraints dictated by the
hardware can now pass those constraints to the client, thereby easing
the use of zero-copy DMA directly into the packet stream.
The alignment is determined by the Block::Session_client at construction
time and applied by the Block::Session_client::alloc_packet method.
Block-session clients should always use this method, not the 'alloc_packet'
method of the packet stream (tx source) directly. The latter merely
applies a default alignment of 2 KiB.
At the server side, the alignment is automatically checked by
block/component.h (old API) and block/request_stream.h (new API).
Issue #3274
This patch modernizes the 'Block::Session::info' interface. Instead of
using out parameters, the 'init' RPC function returns a compound 'Info'
object now. The rather complicated 'Operations' struct is replaced by
a 'writeable' attribute in the 'Info' object.
Fixes#3275
This patch removes the reliance of the extract tool from the libc's
behavior regarding the access of time and timing.
The extract tool is not expected to need time. However, unfortunately,
libarchive calls the 'time' function unconditionally. By adding a
dummy for 'time', we avoid bothering the libc, which would otherwise
need to obtain a time source.
Issue #3204
In the original version, I used 'number_of_bits' because Ada's 'Size
returns the size in bits, not bytes. But the values (for objects) are
always a multiple of 8. On the C++ side, performing size checks at the
granularity of bits is just awkward. The term 'object size' is more
natural.
By adding a wildcard at the beginning of (expected) error messages, the
test.run tool becomes able to match the lines (ignoring the characters
of the color escape sequence).
The "nameserver" file cannot be opened through a VFS File_system client
if the plugin does not support opening the parent directory of
"/nameserver", which would be "/".
Ref #3269
Replace the I/O response handler that is passed to the VFS at
construction with an object that is dynamically attached to handles.
This object shall also accept read-ready notifications, and plugins are
encouraged to keep handles awaiting ready-ready notifications separate
from handles that await I/O progress.
Replace the use of handle lists in plugins with handle queues, this
makes the code easier to understand and the ordering of notifications to
the application more explicit.
These changes replace the use of the Post_signal_hook from all VFS
plugins, applications must assume that read-ready and I/O notifications
occur during I/O signal dispatch and use an Io_progress_handler at its
entrypoints to defer response until after signal dispatching.
Fix#3257
Make sure that the rwlock is allocated before a lock operation is
performed. This case occurs if a static rwlock was create by using
PTHREAD_RWLOCK_INITIALIZER. Same goes for PTHREAD_CONDS_INITIALIZER.
Fixes#3262.
For better or worse we have no proper way of handling this right now
but contrib libraries, e.g. glib, use it to determine if they can use
the underlying fd.
Fxies #3265.
The new configuration attributes <tcp-forward to_port="123" /> and
<udp-forward to_port="123" /> enable manipulating the destination port of
port-forwarded packets.
Fixes#3237
The "Vfs::Vfs_handle" type should not contain any public members that
can be initialized by the VFS internally and by the application, so
remove inheritance from the "Genode::list::Element" class. The VFS
plugins must instead use lists of "Vfs::Vfs_handle" sub-classes, the
lifetime of which are always managed by the plugin.
Ref #3036
This is a follow-up commit to "Update <provides> info in pkg runtimes",
which adapts the users of the wm pkg to the changed label of the "focus"
nitpicker session.
bus or device should be different (not both) when comparing a device to
already present devices. Because of this the second USB device was
marked as existent when the bus matched or the bus did not but the
device number.
The site download.qt.io seems to apply some mirror-via-HTTP-redirect
scheme which, unfortunately, seems broken (and therefore annoyingly
slow) for non-SSL-secured URLs.
The "schedule_post_signal_hook" method of the Genode::Entrypoint class
is problematic because the signal hook can be scheduled and replaced
multiple times during the signal dispatch cycle. Add an alternative to
this method with "register_io_progress_handler" and the "Post_signal_
hook" class with "Io_progress_handler". The difference being an
"Io_progress_handler" may be registered once during the lifetime of an
entrypoint to prevent arbitrary libraries from replacing a pending hook.
The "register_io_progress_handler" remains as a deprecated API, and is
now invoked for every I/O signal received and only for I/O signals
rather than for any signal.
Ref #3132
The zynq nic_drv also depends on hw, we therefore adapted the folder
structure for clarity. Also renamed the binary to 'zynq_nic_drv' to
prevent conflicts and to allow removing the cadence_gem spec.
Issue #3179
'append_platform_drv_config' appends to the global 'config' variable,
which seems to cause problems with the order of appending when the
'config' variable does not contain the '<config>' start node yet.
'[platform_drv_config]' can be used instead to append to a local variable.
Fixes#3171
This patch simplifies the propagation of pointer shapes from
window-manager clients to the pointer. The "shape" report is routed to
the wm server, which, in turn, reports it to the pointer. This way, the
pointer can easily correlate the label of the application's "shape"
report with the label of the application's Nitpicker session. The
formerly used manual rewriting of the "shape" label is not needed
anymore.
Since the wm server provides a "Report" service now, its <provides>
declaration must cover "Report" in addition to "Nitpicker" to avoid
runtime error messages. Vice versa, the wm is now expected to request
"shape" reports, which should be routed to the pointer (using the
'label_last' routing attribute).
Fixes#3165
The lwIP VFS plugin uses lwIP pbuf chains to queue recieved TCP data and
must rechain them when the application dequeues data. Remove an
"pbuf_realloc" call which is not needed for updating pbuf metadata when
dequeuing the head of the chain.
Fix#3169
1) A session request gets denied if there is no matching session policy.
(The <defaul-policy/> tag can be used for the former default behavior)
2) A session request gets denied if the MAC address is given through the
matching policy but this address cannot be allocated.
3) A session request gets denied if the MAC address is not given through the
matching policy and it is also not possible to allocate one.
Issue #3040
This patch adjusts the implementation of the base library and core such
that the code no longer relies on deprecated APIs except for very few
cases, mainly to keep those deprecated APIs in tact for now.
The most prominent changes are:
- Removing the use of base/printf.h
- Removing of the log backend for printf. The 'Console' with the
format-string parser is still there along with 'snprintf.h' because
the latter is still used at a few places, most prominently the
'Connection' classes.
- Removing the notion of a RAM session, which does not exist in
Genode anymore. Still the types were preserved (by typedefs to
PD session) to keep up compatibility. But this transition should
come to an end now.
- Slight rennovation of core's tracing service, e.g., the use of an
Attached_dataspace as the Argument_buffer.
- Reducing the reliance on global accessors like deprecated_env() or
core_env(). Still there is a longish way to go to eliminate all such
calls. A useful pattern (or at least a stop-gap solution) is to
pass the 'Env' to the individual compilation units via init functions.
- Avoiding the use of the old 'Child_policy::resolve_session_request'
interface that returned a 'Service' instead of a 'Route'.
Issue #1987
The minimal-footprint Ada runtime for implementing library-like
functionality in SPARK is now called "spark" runtime.
The full Ada runtime for entire components written in Ada and using the
libc as glue to the underlying system will move to the world repository
as "ada" runtime.
Issue #3144
Also added a report_rom for USB devices and let the driver report like
in a real scenario. Can also be used for debugging by setting
verbose="yes" in report_rom.
The former 'Genode::Timed_semaphore' mechanism is moved to the private
part of the two remaining users, namely dde_rump and the libc. Note
there are now two private copies of 'timed_semaphore.h'. This should be
regarded as an interim step until the use of this mechanism is removed
from both users.
This patch also cleans up the mechanism from legacy Genode API calls and
global side effects (alarm-thread singleton). The test/timed_semaphore
is now located at the libports repository as it now tests a mechanism of
the libc. The former timed_semaphore library is no more.
Fixes#3121
Store all files generated by moc and rcc in the application's build
