Former Native_config::context_area_virtual_base() was used to identify
the main, which is not desired as the Native_config is rather low-level
(almost private to the base libs). The commit uses a library constructor
to retrieve the main-thread Thread_base pointer, which can be used later
to distinguish main and other threads.
The test performs several rounds of write-read cycles with the following
configuration attributes in a <write-read> config node
rounds determines the number of rounds (default is 4)
size determines the number of bytes written/read in one round
(default is 4 MiB)
buffer_size determines the size of the write-read buffer
(default is 32 KiB)
In one round the test writes and reads "size/buffer_size" times
from/into a buffer_size'd buffer.
The pthread object for the main thread initializes its 'Thread_base' base
class part with a reference to the 'Thread_base' object of the Genode main
thread. Therefore the pthread object for the main thread should never be
destroyed, as this would also destroy the Genode 'Thread_base' object.
Fixes#1760
The RAM quota currently dedicated to the wm and decorator components in
the 'qt5_common.inc' file is too low for a window of size 1920x1080.
Fixes#1761
Defer destruction of threads which tries to self-destruct. Check an perform
cleanup of such threads during pthread_cancel and pthread_create.
Issue #1687
The 'O_NONBLOCK' flag has different numerical values in lwip and in the
libc, which prevented the correct setting of nonblocking socket mode.
Fixes#1699
Instead of holding SPEC-variable dependent files and directories inline
within the repository structure, move them into 'spec' subdirectories
at the corresponding levels, e.g.:
repos/base/include/spec
repos/base/mk/spec
repos/base/lib/mk/spec
repos/base/src/core/spec
...
Moreover, this commit removes the 'platform' directories. That term was
used in an overloaded sense. All SPEC-relative 'platform' directories are
now named 'spec'. Other files, like for instance those related to the
kernel/architecture specific startup library, where moved from 'platform'
directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.
Fix#1673
Run script depending on VFS plugins (i.e., shared objects) like
vfs_jitterentropy.lib.so have to state this dependency rather the actual
binaries linked against libc. The latter introduces a library dependency
that is just not there. For example, the dependency on vfs_jitterentropy
is a result from the config node for libc which automatically loads the
plugin.
With the introducation of the Audio_in session interface it makes
sense to rename the current available audio drivers. At the moment
only the dde_bsd audio_drv supports Audio_out as well as Audio_in.
The Linux audio_drv only supports Audio_out (there is no demand for
Audio_in support currently) but is renamed nonetheless to make it
easiert to write generic run scripts.
Issue #1644.
Move FS Node implementations from server/ram_fs to include/ram_fs.
Support embedded ram_fs instances in VFS configurations using <ram/>.
Add 'no space' handling to VFS symlink ops.
Fixes#1635
Allow symlinks to be passed to the read and write file system utilities.
Disallow writes to symlinks with offsets in file system servers, this is
to ensure that writing the target of a symlink is an atomic operation.
Fixes#1604
SDL uses the Audio_out session in streaming fashion. For this reason
the audio might be played with delay of at most the queue size. To
mitigate the effect we synchronize the tail pointer to the current play
pointer when the PlayAudio() function is called by SDL for the first
time.
Fixes#1612.
