- Stop refreshing if all CPUs go to sleep, also in text mode.
- Any input resets update rate to 100Hz in graphic mode, which gets
decreased step by step down to 25Hz if no input is available (looking video
without input by user).

Make sure timers run at the same priority as component threads, otherwise
no timer progress can be made. See 'rtTimeNanoTSInternalRef' (timesupref.h)
and 'rtTimerLRThread' (timerlr-generic.cpp).
This is a follow-up patch for "noux: don't update mtimes for read-only
files". It eliminates warning messages during Sculpt's prepare step when
'cp' tries to update the mtimes of the source files.
This is a follow-up patch for issue #1784 that solves two
inconsistencies.
- The Vfs::Timestamp::INVALID matches File_system::Timestamp::INVALID
- The Noux libc plugin tests for Timestamp::INVALID instead of a
positive value.
The patch fixes the mtime info as shown in directory listings in
Sculpt's inspect window.
required due to pthreads becoming/are an integral part of the libc now.
Commit avoids libc error:
Error: libc suspend() called from non-user context (0xaf5c784) - aborting
Issue #3550
This is an intermediate fix to handle sends to sockets shut down by the
peer already. A final fix in the libc would add support for the
MSG_NOSIGNAL send flag, generate SIGPIPE, and return the expected EINTR.
Then this patch is no longer required.
This commit also drops the obsolete patch for missing
sysconf(_SC_NPROCESSORS_ONLN), which is now part of libc.
The VFS server as reworked in issue #3547 responds to such an attempt
with a failure as acknowledgement, triggering the client-side error
"Error: packet operation=2 failed" at noux.
As genode.org site is now protected by TLS and unencrypted site
is redirected to enctypted one, download URL should be modified
to reflect this change.
Without this change, wget downloads just index.html file.

Fixes#3538
This patch extends the 'File_system::Status',
'File_system::Directory_entry', and the related 'Vfs' types with
the following additional information:
- Distinction between continuous and transactional files (Node_type)
(issue #3507)
- Readable, writeable, and executable attributes (Node_rwx),
replacing the former 'mode' bits
(issue #3030)
The types 'Node_rwx', 'Node_type' are defined twice,
once for the VFS (vfs/types.h) and once for the 'File_system'
session (file_system_session/file_system_session.h).
Similarly, there is a direct correspondance between
'Vfs::Directory_service::Dirent' and 'File_system::Directory_entry'.
This duplication of types follows the existing pattern of keeping the
VFS and file-system session independent from each other.
... and set initial time by using RTC session.
Up to now Noux used a monotic clock whose initial start value always
was '0' (which correlates to the start of the UNIX epoch) to provide
a notion of time. In addition it is now possible to use the RTC
session to set the initial value for use cases where having a proper
real-world time matters.
To use the RTC session the 'rtc' attribute of the '<config>' node
must be set to 'yes'. Thereby the session becomes a mandatory
dependency as Noux will not start without it.
Issue #1784
This patch complements the commit "libc: execve" with the ability to
execute files stored at arbitrary sub directories of the file system.
Issue #3481
Issue #3500
This patch is the first step of re-organizing the internal structure of
the libc. The original version involved many direct calls of global
functions (often with side effects) across compilation units, which
made the control flow (e.g., the initialization sequence) hard to
follow.
The new version replaces those ad-hoc interactions with dedicated
interfaces (like suspend.h, resume.h, select.h, current_time.h). The
underlying facilities are provided by the central Libc::Kernel and
selectively propagated to the various compilation units. The latter is
done by a sequence of 'init_*' calls, which eventually will be replaced
by constructor calls.
The addition of new headers increases the chance for name clashes with
existing (public) headers. To disambiguate libc-internal header files
from public headers, this patch moves the former into a new 'internal/'
subdirectory. This makes the include directives easier to follow and the
libc's source-tree structure more tidy.
There are still a few legacies left, which cannot easily be removed
right now (e.g., because noux relies on them). However, the patch moves
those bad apples to legacy.h and legacy.cc, which highlights the
deprecation of those functions.
Issue #3497
This patch implements 'execve' in Genode's libc.
The mechanism relies on the dynamic linker's ability to replace the
loaded binary while keeping crucial libraries - in particular the libc -
intact. The state outside the libc is wiped. For this reason, all libc
internal state needed beyond the 'execve' call must be allocated on a
heap separate from the application-owned malloc heap. E.g.,
libc-internal file-descriptor objects must not be allocated or refer to
any memory object allocated from the malloc heap.
Issue #3481
This patch extends the fork test with explicit checks for the cloned
content of the heap and RW segment as well as the seek position of an
open file descriptor. It adds the new libports/run/fork.run script
that exercises the fork mechanism implemented by the libc. It is based
on noux_fork.run, which tests the mechansim provided by noux. The
test program has been moved from ports to libports.
