* Switch mesa support from DRI to gallium
Supported drivers are
- softpipe (Sebstian Sumpf)
- iris for Intel GPUs (Alexander Boetcher)
- etnaviv for Vivante GPUs (Josef Söntgen)
* Mesa's generated files are placed into 'contrib/mesa-<hash>/generated'
and are cloned per default from a separate Git repo in order to avoid
hash updates upon package build. In case you need to generate files
yourself use
! prepare_port mesa GENERATE_FILES=1
issue #4254
Support for iris and etnvaviv
* entaviv:
- libdrm on FreeBSD is not prepared for !PCI (and libc our is missing
<sys/pciio.h>
- missing <sys/types.h> include in xf86drmMode.c
- etnaviv relies on linux header files - dummy in $(INC_DIR)
- IOCTL FreeBSD ↔ Linux have swapped IO/OUT bit
- O_CLOEXEC differs between FreeBSD ↔ Linux
issue #4254
- API packages for: libusb, libuvc, and libyuv
- Source packages for: API packages + USB webcam app
- Meta package for USB webcam
- Raw package for USB webcam configuration

The vfs pipe plugin can now be used as named pipe which anables data
transfer via file handles from one component to another. E.g. if one
would like to send data from component A to stdin of a libc component B,
one can do so by simply writing to that fifo file.

Note, OpenSSL now comes as one combined depot archive *openssl* that
replaces the former *libssl* and *libcrypto* archives. The libraries are
still separate binaries for compatibility with legacy software.
Issue #3773
This plugin gives access to the Audio_out session by roughly
implementing a OSS pseudo-device. It merely wrapps the session and does
not provide any resampling or re-coding.
Fixes#3891.
* add libsparkcrypto source-recipe
* provide ALI files through a new repository by mstein and add the repo
download to the libsparcrypto port-file
* remove dependencies to non-existent contrib ADB files from the library make
files
Fixes: #3852
* switch to fork of the Ada runtime provided by m-stein
* switch to a Ada-runtime state that provides the Exp_Int package (exponential
function on integers)
* adapt spark lib, symbols, and recipes to incorporate the Exp_Int package
Fixes#3848
This patch replaces the use of the "Framebuffer" session interface by
the new "Capture" session interface in all framebuffer drivers. Thanks
to this change, those drivers have become mere clients of the nitpicker
GUI server now, and are no longer critical for the liveliness of the GUI
server.
The patch touches the following areas:
- The actual driver components. The new versions of all drivers have
been tested on the respective hardware. Generally, the drivers
have become simpler.
- The drivers_interactive packages for various boards. The drivers
subsystem no longer provides a "Framebuffer" service but needs a
valid route to the "Capture" service provided by nitpicker.
- The driver manager of Sculpt OS.
- This patch changes the role of the test-framebuffer component from a
framebuffer client to a capture server so that drivers (capture clients)
can be directly connected to the test component without the nitpicker
server.
- Framebuffer driver no longer support the unbuffered mode.
- The fb_bench.run script is no longer very meaningful because it
interplays solely with nitpicker, not with the driver directly.
- All run scripts for graphical scenarios and the related depot
archives got adapted to the change.
Fixes#3813
The former ldso-startup static library (now called ldso_so_support) is
used to spice each shared object/library with local support code for the
dynamic linker (execution of static constructors and ARM-EABI).
Therefore, the library must be statically linked to each dynamic
library.
As a result recipes for dynamic libraries must always depend on the "so"
API, which makes ldso_so_support.mk and so_support.c available
independent of "base". Additionally, ldso_so_support is also provided in
the libc API to cut the dependency early for libc/posix libraries.
Issue #3720
Generated a separate 'config.h' for arm, arm_64, x86_32, x86_64 for the
current version (6.1.2) of GMP. This became necessary because
configurations differ for each architecture.
'config.h' generaton on x86_64 host in'gmp-6.1.2' directory:
for x86_64 (native):
! configure
for x86_32:
! configure --host=x86-pc-linux-gnu --build=x86_64-pc-linux-gnu
for arm:
! configure --host=arm-linux-gnu --build=x86_64-pc-linux-gnu \
! CC=/usr/local/gcc-linaro-arm/bin/arm-linux-gnueabi-gcc ABI=32
for arm_v8:
! configure --host=aarch64-linux-gnu --build=x86_64-pc-linux-gnu \
! CC=/usr/local/gcc-linaro/bin/aarch64-linux-gnu-gcc ABI=64
issue #3598
Add a new plugin for creating pipes between pairs of VFS handles. It is
intended to replace the libc_pipe plugin, one of the last remaining libc
plugins.
In contrast to the libc_pipe plugin, this plugin defers cross-handle
notification until I/O signal handling rather than block and unblock
readers using a semaphore. This is a performance regression in the case
of multiple threads blocking on a pipe, but shall be an intermediate
mechanism pending renovations within the libc VFS and threading layers.
As a side effect, threads blocked on a pipe might not be resumed until
the main thread suspends and dispatches I/O signals.
The "test-libc_pipe" test has been adjusted to use the VFS pipe plugin
and tests both local pipes and pipes hosted remotely in the VFS server.
Merge adaptations (such as EOF handling, adjustment to VFS/libc
interface changes) by Norman Feske.
Fix#2303
This patch is the first step of re-organizing the internal structure of
the libc. The original version involved many direct calls of global
functions (often with side effects) across compilation units, which
made the control flow (e.g., the initialization sequence) hard to
follow.
The new version replaces those ad-hoc interactions with dedicated
interfaces (like suspend.h, resume.h, select.h, current_time.h). The
underlying facilities are provided by the central Libc::Kernel and
selectively propagated to the various compilation units. The latter is
done by a sequence of 'init_*' calls, which eventually will be replaced
by constructor calls.
The addition of new headers increases the chance for name clashes with
existing (public) headers. To disambiguate libc-internal header files
from public headers, this patch moves the former into a new 'internal/'
subdirectory. This makes the include directives easier to follow and the
libc's source-tree structure more tidy.
There are still a few legacies left, which cannot easily be removed
right now (e.g., because noux relies on them). However, the patch moves
those bad apples to legacy.h and legacy.cc, which highlights the
deprecation of those functions.
