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.
One of the Qt5 patches is supposed to create symbolic links, which is not
supported by GNU patch before version 2.7. Using 'git apply' to apply the
patches solves this problem.
Fixes#969.
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
This patch updates the launchpad config to use XML attributes and
removes the built-in default configuration (which is only meaningful
for demo.run anyway).
By splitting Session_policy into two classes, we make it more flexible.
Originally, the constructor accepted solely an args string, which made it
unusable for situations where we already have extracted the session
label (e.g., stored in the session meta data of a server). Now, the
extraction of the label from the args string is performed by the new
Session_label class instead, which, in turn, can be passed to the
constructor of Session_policy.
This change causes a minor API change. The following code
Session_policy policy(session_args);
Must be turned into
Session_label label(session_args);
Session_policy policy(label);
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.
This patch adds some of lwip's checksum calculation options to the
Genode-specific 'lwiptops.h' configuration file. The checksum calculations
are enabled by default.
Fixes#868.
Only the directories and files which were created in the first place
by the libc port should be removed. Thereby ignore the exit code of
the find command to prevent GNUmake from stopping its execution.
Fixes#841.
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.
The window scale option (http://tools.ietf.org/html/rfc1323) patch of lwIP
definitely works solely for the receive window, not for the send window.
Setting the send window size to the maximum of an 16bit value, 65535,
or multiple of it (x * 65536 - 1) results in the same performance.
Everything else decrease performance.
We will have to check this window scale patch before using higher values.
