In the presence of potentially multiple output back ends, this
dirty_rect state must be maintained individually per back end. Instead
of storing the dirty_rect as view-stack member, the view stack now calls
a new 'Damage::mark_as_damaged' interface, which allows nitpicker to
propagate this information to multiple back ends. Unfortunately, the
patch must remove the per-view dirty_rect state.
Issue #3812
This patch simplifies the internal naming of the nitpicker GUI server as
a preparatory step for adding support for the capture session interface.

_timestamp() returns CPU local values which may not be in sync with _ts
taken from another CPU. Be robust and don't produce wraparound/negative
timeout values.

* Differentiate in between different architectures with assembler routines
for correct measures
* Automate first step measuring of 10G bogomips across different hardware
Fix#3785
Until now, Genode's framebuffer session interface was based on the
RGB565 pixel format. This patch changes the pixel format to 32-bit
XRGB where the X part is ignored. It adapts all graphical applications
and device drivers accordingly.
The patch also adjusts the users of the drivers_interactive packages,
assigning 64 MiB RAM and 1500 caps to the drivers subsystem, which is
sufficient for covering high resolutions at 32 bits per pixel and to
accommodate multi-component USB HID input stacks.
Fixes#3784
The 'vfs_block' component will give access to a VFS file through a
Block session. For more detailed information please look at its
README.
(On a technical note, the server currently only allows for one
active session and has only one pending back end request but can
easily be extended in the future.)
Fixes#3781.
Setting the 'size' attribute will restrict a reader to consume
0s up to the specified amount per VFS handle. The attribute is
parsed as 'Number_of_bytes', which will limit the amount to the
maximum of the addressable memory on the platform.
This addition comes in handy when needing to provide a synthetic
empty file with a fixed size.
Issue #3781.
So far the condition whether to spawn a new job or not depended on
the amount of data already processed. This could lead to spawning
more jobs than necessary if batching is used and in return could
result in creating invalid requests in case the tested block session
is not large enough.
In addition to checking the amount of data the test now stores the
number of the last block and checks if the current request is in
range. This properly limits the total amount of requests.
Issue #3781.
The seek offset has to be updated on partial writes according to the
current write position. Otherwise writes will override the content
at the initial offset.
Fixes#3780.
This commit fixes the 'Out_of_caps' handling. The previous version
mistakenly upgraded the RAM instead the caps as response. The problem
could be triggered by the 'decorator_stress.run' script.
The blit API archive missed the CPU-architecture-specific variants of
the blit library such that all depot binaries worked with the generic
(slow) fallback implementation. This patch adds the missing pieces to
the blit API archive.
Up to now all pthreads get placed on one CPU.
The patch adds support to evaluate a libc pthread configuration specifying
a placement strategy.
The default strategy is now to use all available CPUs as imposed by Genode's
affinity configuration for the pthread application.
The old behaviour, putting all pthreads on one single cpu can be still
configured by:
<libc>
<pthread placement="single-cpu"/>
...
</libc>
Fixes#3775
To enable logging of ROM session deliveries, set the "diag" on
session routes:
<route>
<service name="ROM" label_prefix="/bin/">
<child name="cached_fs_rom" diag="yes"/>
</service>
…
<route>
Fix#3772
Make the framebuffer driver for pl11x chipsets,
the ps2 input driver for pl050, and the lan9116 NIC driver independent from
the pbxa9 board by using the newly introduced common ARM platform driver API.
Ref #3299
* Remove input driver specific to i.MX53 tablet board from QSB driver pkg
* Move GPIO settings for QSB LVDS backlight out of framebuffer driver into
GPIO driver config
* Move PWM driver functionality out of framebuffer driver
* Make framebuffer driver configureable, and less dependent on
platform driver i.MX53 specifics
base-linux uses seccomp to reduce the available system calls
to the minimum set needed to run base-linux. There are still
some syscalls that allow accessing global state which should
be further reduced.
The combination of seccomp and socket descriptor caps should
provide an intermediate level of security for base-linux
thereby enabling base-linux as a migration path from using
the Linux kernel to the use of microkernel-based Genode.
Fixes#3581
Add the option to configure the RAM quota for core on base-linux.
The environment variable GENODE_RAM_QUOTA if it exists is interpreted
as number of bytes to provide to the first init.
