With this patch, the VESA driver chooses the video mode with the highest
resolution from the list of available modes if no resolution is
explicitly configured.
Fixes#1263.
* use seoul branch containing vbios emulator
* report the memory model in the VBE mode info as otherwise the
Genode framebuffer driver will ignore this mode
Fixes#1261
It turned out that the controller configuration can change during the self
tests, so now it is read before running the tests and restored afterwards.
Fixes#1260.
This component merges the input events of multiple sources.
Example configuration:
<start name="input_merger">
<resource name="RAM" quantum="1M" />
<provides>
<service name="Input" />
</provides>
<config>
<input label="ps2" />
<input label="usb_hid" />
</config>
<route>
<service name="Input">
<if-arg key="label" value="ps2" /> <child name="ps2_drv" />
</service>
<service name="Input">
<if-arg key="label" value="usb_hid" /> <child name="usb_drv" />
</service>
<any-service> <parent /> <any-child /> </any-service>
</route>
</start>
For each 'input' config node, the component opens an 'Input' session with the
configured label. This label is then evaluated by 'init' to route the session
request to a specific input source component.
Fixes#1259.
* When flushing the data and unified cache on ARM, clean and invalidate
instead of just cleaning the corresponding cache lines
* After zero-ing a freshly constructed dataspace in core, invalidate
corresponding cache lines from the instruction cache
The backend allocator for the slab is a sliced heap, which hands out
allocations with page-size granularity (4096 bytes). Therefore, the
slab-block size should also be about a multiple of the page size minus
some bytes of overhead.
Additional adjustments:
- The slab-block size and the default quota-upgrade amount for SIGNAL
sessions depends on the platform bit width now.
- The signal test also stresses the case of many managed context in one
session including creation and destruction of the used signal receiver
in repeated rounds.
- correctly catch and report non-existing root directories
- remove *all* leading slashes from root-directory attributes and
sanitize empty declarations to current working directory
The weak implementation was added for quite special purposes years ago
and is no longer needed. On the other hand, the weak attribute does not
help if the implementation ends up in a shared library, which first
resolves symbols locally before asking ldso (that includes the acutal
thread library) *shiver*
The original git:// URL produced the following error:
Cloning into 'jbig2dec'...
fatal: remote error: access denied or repository not exported: /jbig2dec.git
Before the pointer handling was removed from the nitpicker server, the
pointer was always the first view, which was skipped in the find_view
function. However, since we support pointer-less operation by now, we
have to consider all views starting with the top-most one.
The port was succesfully tested a echo test and lighttpd. DHCP over
OpenVPN is not tested and probably will not work out of the box.
Therefore, the ip address etc. need to be specified manually.
For now, only ethernet bridging (using a TAP device) is supported.
Fixes#1235.
This commit adds a port the jitterentropy library to Genode. As
backend on x86_{32,64} 'rdtsc' is used and on ARMv{6,7} the
performance-counter.
Fixes#1239.
These file systems are provided on-demand by loading a shared library
when the fstab node is traversed. By convention this library is named
after the file system it provides. For example a file system that
provides a 'random' file system node is called 'vfs_random.lib.so'. It
is still possible to give the the node another name in the vfs. The
following code snippts illustrates this matter:
! [...]
! <config>
! <libc>
! <vfs>
! <dir name="dev"> <jitterentropy name="random"/> </dir>
! </vfs>
! </libc>
! </config>
! [...]
Here the jitterentropy file system, implemented in
'vfs_jitterentropy.lib.so' provides a file system node named 'random'
in the 'dev' directory. When traversing the vfs section the libc will
try to load 'vfs_jitterentropy.lib.so' but programs may access the
file system only via '/dev/random'.
Fixes#1240.
This patch fixes a potential race condition that could happen if a
client connects to nitpicker before the signal for the import of the
initial configuration was delivered. In this case, nitpicker would be
unable to assign a domain to the session (because this information comes
from the configuration), rendering subsequent calls to 'mode' invalid.
The patch solves this problem by manually calling the signal handler
for importing the configuration.
This provides bootable disk images for x86 platforms via
! RUN_OPT="--target disk"
The resulting disk image contains one ext2 partition with binaries from
the GRUB2 boot loader and the run scenario. The default disk size fits
all binaries, but is configurable via
! --disk-size <size in MiB>
in RUN_OPT.
The feature depends on an grub2-head.img, which is part of the commit,
but may also be generated by executing tool/create_grub2. The script
generates a disk image prepared for one partition, which contains files
for GRUB2. All image preparation steps that need superuser privileges
are conducted by this script.
The final step of writing the entire image to a disk must be executed
later by
sudo dd if=<image file> of=<device> bs=8M conv=fsync
Fixes#1203.
After modifying mode transition for branch prediction tz_vmm wasn't
working anymore on hw_imx53_tz but the modifications had nothing to do
with the VM code. However, the amount of instructions in the MT before the
VM exception-vector changed. So I tried stuffing the last working version with
NOPs and found that tz_vmm worked for some NOP amounts and for others not.
Thus, I increased the alignment of the VM exception-vector from 16 bytes to 32
bytes, é voila, its working with any amount of NOPs as well as with branch
prediction commits.
ref #474
Previously, we did the protection-domain switches without a transitional
translation table that contains only global mappings. This was fine as long
as the CPU did no speculative memory accesses. However, to enabling branch
prediction triggers such accesses. Thus, if we don't want to invalidate
predictors on every context switch, we need to switch more carefully.
ref #474
The console included nitpicker_view headers, which were not used. The
headers vanished with the recent nitpicker API change, which broke the
build of seoul.
This patch reimplements the nit_fb server using the server API and
thereby enables the dynamic resizing the of the framebuffer.
Note that the new implementation does not feature the ability to perform
a periodic refresh via the 'refresh_rate' configuration argument. This
feature was removed because the refresh policy can (and should) always
be implemented on the client side.
The QPluginWidget used to be a QNitpickerViewWidget but the new loader
interface does no longer hand out a view capability. So we need to
decouple both classes. This patch moves the view-geometry calculation to
a separate class to make it easier reusable, in particular for the
QPluginWidget.
The window manager provides a nitpicker session interface. In contrast
to the nitpicker server, which leaves the view layout up to the client,
the window manager organizes the views on screen according to a policy
provided by a window layouter. Furthermore, it equips views with window
decorations as provided by a window decorator. Both layouter and
decorator are independent programs.
