Splitting the new Genode::Deallocator interface from the former
Genode::Allocator interface enables us to restrict the accessible
operations for code that is only supposed to release memory, but not
perform any allocations.
Additionally, this patch introduces variants of the 'new' operator
that takes a reference (as opposed to a pointer) to a Genode::Allocator
as argument.
By assigning the file name as label, we may become able to remove the
filename argument in the future by just interpreting the last part of
the label as filename. By keeping only the label, we won't need to
consider conditional routing (via <if-arg>) based on session arguments
other than the label anymore.
The new Attached_dataspace complements the existing Attached_*
utilities with a simple version that can be used with any kind of
dataspaces. It may be even useful as a common base type for the other
variants. For example, this patch simplifies Attached_rom_dataspace
and removes the Terminal::Client::Io_buffer.
This patch integrate the scout widgets with Genode's new API headers
'util/geometry.h', 'os/surface.h' and 'os/texture.h'. Thereby, we get
almost rid of the platform-abstraction shim that was never used anyway.
Furthermore, it extracts the parts that are worth reusing from the
scout implementation to the public location 'demo/include/scout'.
This patch re-arranges nitpicker's graphics backend in a more modular
and expandable way. Generalized versions of the 'Canvas',
'Chunky_canvas', and 'Pixel_*' classes have been moved to
'os/include/util/' and 'os/include/os'. The only remaining parts that
are specific to nitpicker's needs are a few drawing functions, each
located in a distinct header at 'os/include/nitpicker_gfx/'.
This patch makes nitpicker's geometry utilities available for the use
by other programs. Thereby, the 'Point', 'Area', and 'Rect' classes
have become templates that take the coordinate type and distance type
as arguments.
Unless '-ignorestderr' is set on 'exec' in expect, any output on stderr
is interpreted as execution failure. In this case, 'create_iso' logs
some diagnostics but does not fail.
We repeatedly promote our ISOs to be bootable from USB storage.
Therefore, we have a hard dependency on 'isohybrid' and should fail in
the case that the tool is missing.
Access to a block session is provided by using the block file system.
By specifying the label, each block session request can be routed to
the proper block session provider:
! <fstab>
! ...
! <dir name="dev">
! <block name="blkdev0" label="block_session_0" />
! </dir>
! ...
! </fstab>
In addition to this file system, support for the DIOCGMEDIASIZE ioctl
request was added. This request is used by FreeBSD and therefore our
libc to query the size of the block device in bytes.
Fixes#1010.
All source codes of the glue code between Vancouver and Genode that were
based on existing GPL code had already stated that Genode Labs is not
the sole owner of the code. To make the distinction between the Genode
OS framework and the glue code more clear, this patch removes the text
"is part of the Genode OS framework" from the glue code.
Instead of, passing responsibility to manage and dissolve Signal_rpc_member
objects at a corresponding entrypoint to the user, hand over entrypoint's
reference to the constructor, and do it in the constructor resp. destructor
of the class.
Fixes#1022
Both base/src/test/thread and base-okl4/src/test/okl4_03_thread used the
same target name, which ultimately confused the build system when
building on OKL4.
File systems using the File_system_session interface can now be
synchronized by using this syscall. This is needed for file system
that maintain an internal cache, which should be flushed.
Fixes#1008.
