The Genode-specific implementation of 'QWaitCondition' contains a race
condition which can make the 'qt5_samegame' application hang on Fiasco.OC.
Since most of the pthread synchronization functions needed by the
UNIX-specific implementation of 'QWaitCondition' and 'QMutex' are
available now, we can use these now instead of fixing and keeping
the Genode-specific implementation.
Fixes#993.
This patch enables experimental QML support in Qt5.
Only the QtQuick plugin is available yet.
Currently runs best on Linux and has some problems on NOVA and Fiasco.OC.
Fixes#979.
Replace the static lock with the file descriptor lock because recursive
calls of p{read,write} would result in a deadlock when using multiple
libc-plugins at the same time.
Fixes#948.
This FUSE implementation consists of libfuse, which provides a
subset of the FUSE 2.6 API and libc_fuse, which provides support
for accessing FUSE based file system via the libc.
Fixes#942.
Among other changes, this patch makes it possible to let Mesa render into
a user-provided buffer instead of the screen. This can be achieved with
the 'eglCreateWindowSurface()' function, which takes a buffer
description as third argument.
Fixes#974.
A timer session is now used instead of a jiffy counter. This way, libSDL
can use a time source that is not bound to the granularity our libc's
nanosleep implementation. Currently, the granularity of nanosleep is in
the order of 10 milliseconds, which is far to coarse for the use of
SDL-using applications such as DosBox.
Fixes#934.
This patch changes the interface of Nitpicker to support dynamically
dimensioned virtual frame buffers. This solves two problems:
First, it enables a client to create a connection to nitpicker without
donating much session quota in advance. The old interface required each
screen-size-dependent client to donate as much memory as needed to
allocate a screen-sized virtual framebuffer. For clients that are
interested int the screen size but cover just a small portion of the
screen (e.g., a banner, a menu, an applet that sits in the screen
corner), this overprovisioning is painful. The new interface allows such
clients to upgrade the session quota for an existing session as needed.
Second, because each nitpicker session used to have a virtual frame
buffer with a fixed size over the lifetime of the session, a client that
wanted to implement a variable-sized window had to either vastly
overprovide resources (by opening a session as large as the screen just
in order to be prepared for the worst case of a maximized window), or it
had to replace the session by a new one (thereby discarding the stacking
order of the old views) each time the window changes its dimensions. The
new interface accommodates such clients much better.
* Remove far too low default values from Nic::Connection constructor
* Extend lwip initialization function with desired TX/RX buffer sizes
* Add configuration possibility to libc_lwip_dhcp plugin to define
buffer sizes, like the following:
'<libc tx_buf_size="1M" tx_buf_size="1M"/>'
Fixes#892
Originally, the convenience utility for accessing a process
configuration came in the form of a header file. But this causes
aliasing problems if multiple compilation units access the config while
the configuration gets dynamically updated. Moving the implementation of
the accessor to the singleton object into a library solves those
problems.
This patch adds support for iterating through a const list. This allows
users of lists to be more rigid with regard to constness. Furthermore,
the patch adds the function 'List::insert_at' for inserting an element
at a specified position. By adding this function, we can remove code
duplication in nitpicker.
With this patch, the 'not implemented' messages of the pthread function
stubs always get printed to the Genode log console instead of stdout.
Issue #815.
In fact, the sizes were the same the whole time, but by using
the same enum in both cases to instantiate the Packet_stream_tx
and Packet_stream_rx members of the e.g. RPC object, it allows
for more flexible generalization between e.g. source or, sink
objects, when programming event-driven, and implementing generic
handlers for their signals.
lwIP only supports the 'AF_INET' domain, but doesn't check the 'domain'
argument of the 'lwip_socket()' function.
This patch avoids an error message from lwIP when the Arora browser
tries to connect a socket of the 'AF_LOCAL' domain.
Fixes#732.
With this patch, the 'libc_lwip_nic_dhcp' plugin provides the DNS server
address acquired by lwIP via DHCP in the file '/etc/resolv.conf'.
This feature can be disabled from the config file:
<libc resolv="no" />
The static network interface configuration attributes are now also a part
of the '<libc>' config node:
<libc ip_addr="..." netmask="..." gateway="..." />
Fixes#731.
This patch simplifies the way of how Genode's base libraries are
organized. Originally, the base API was implemented in the form of many
small libraries such as 'thread', 'env', 'server', etc. Most of them
used to consist of only a small number of files. Because those libraries
are incorporated in any build, the checking of their inter-dependencies
made the build process more verbose than desired. Also, the number of
libraries and their roles (core only, non-core only, shared by both core
and non-core) were not easy to capture.
Hereby, the base libraries have been reduced to the following few
libraries:
- startup.mk contains the startup code for normal Genode processes.
On some platform, core is able to use the library as well.
- base-common.mk contains the parts of the base library that are
identical by core and non-core processes.
- base.mk contains the complete base API implementation for non-core
processes
Consequently, the 'LIBS' declaration in 'target.mk' files becomes
simpler as well. In the most simple case, only the 'base' library must
be mentioned.
Fixes#18
