To actually receive audio input in a particular VM, it also
needs to be enabled in the vbox file:
<AudioAdapter controller="HDA" driver="OSS" enabled="true"
enabledOut="true" enabledIn="true"/>

On some boards or emulators a CPU might be executing in hyp mode
when entering Genode's bootstrap code. In that mode the 'cps' instruction
is not defined. Therefore, we change the way the boot cpu is identified.

* renamed rpi pic to Bcm2835_pic
* renamed rpi3 pic to Bcm2837_pic
* added bcm2837 control for setting prescaler value (to fix timer_accuracy)
* changed handling of all interrupts for rpi3 by cascading to bcm2835 pic
* rpi3 irq controller base address made consistent with rpi
* added usb controller memory region for pic on rpi3 (for SOF interrupts)

The socket type (in the lower bits) maybe ORed with SOCK_CLOEXEC and
SOCK_NONBLOCK options (in the higher bits). Currently, supported values
are SOCK_STREAM (1) and SOCK_DGRAM (2), so just take the lower 2 bits.
This fixes treating `SOCK_STREAM` sockets as UDP if additional flags
were set.
Fixes#4370
This patch equips Sculpt with the ability to customize the system image
in very flexible ways.
All customizable aspects of the image have been relocated from the
former sculpt.run script and the accompanied gems/run/sculpt/ directory
to a new location - the sculpt/ directory - which can exist in any
repository. The directory at repos/gems/sculpt/ serves as reference.
The sculpt directory can host any number of <name>-<board>.sculpt files,
each containing a list of ingredients to be incorporated into the
Sculpt system image. The <name> can be specified to the sculpt.run
script. E.g., the following command refers to the 'default-pc.sculpt'
file:
make run/sculpt KERNEL=nova BOARD=pc SCULPT=default
If no 'SCULPT' argument is supplied, the value 'default' is used.
A .sculpt file refers to a selection of files found at various
subdirectries named after their respective purpose. In particular, There
exists a subdirectory for each file in Sculpt's config fs, like
nitpicker, drivers... The .sculpt file selects the alternative to use
by a simple tag-value notation.
drivers: pc
The supported tags are as follows.
*Optional* selection of /config files. If not specified, those files are
omitted, which prompts Sculpt to manage those configurations
automatically or via the Leitzentrale GUI:
fonts
nic_router
event_filter
wifi
runtime
gpu_drv
Selection of mandatory /config files. If not specified, the respective
'default' alternative will be used.
nitpicker
deploy
fb_drv
clipboard
drivers
numlock_remap
leitzentrale
usb
system
ram_fs
Furthermore, the .sculpt file supports the optional selection of
supplemental content such as a set of launchers.
launches: nano3d system_shell
Another type of content are the set of blessed pubkey/download files
used for installing and verifying software on target.
With the new version, it has become possible to supply a depot with the
the system image. The depot content is assembled according to the 'pkg'
attributes found in launcher files and the selected deploy config.
The resulting depot is incorporated into the system image as 'depot.tar'
archive. It can be supplied to the Sculpt system by mounting it into the
ram fs as done by the 'ram_fs/depot' configuration for the ram fs.
It is possible to add additional boot modules to the system image. There
are two options.
build: <list of targets>
This tag prompts the sculpt.run script to build the specified targets
directly using the Genode build system and add the created artifacts
into the system image as boot modules.
import: <list of depot src or pkg archives>
This tag instructs Sculpt to supply the specifid depot-archive content
as boot modules to the system image. This change eliminates the need for
board-specific pkg/sculpt-<board> archives. The board-specific
specializations can now be placed directly into the respective .sculpt
files by using 'import:'.
To make the use of Sculpt as testbed during development more convenient,
the log output of the drivers, leitzentrale, and runtime subsystems
can be redirected to core using the optional 'LOG=core' argument, e.g.,
make run/sculpt KERNEL=linux BOARD=linux LOG=core
The former pkg/sculpt-installation and pkg/sculpt-installation-pc
archives have been replaced by pkg/sculpt_distribution-pc, which
references the generic pkg/sculpt_distribution archive. Those pkgs are
solely used for publishing / distribution purposes.
Fixes#4369
The new function 'build_artifacts' returns a list of artifacts created
by the Genode build system. The list can be supplied as argument to
the 'build_boot_image' function.
Note that the list covers only program targets and shared libraries.
Other artifacts created as side effects of custom rules are not covered.
Fixes#4368
This patch prevents the run tool from issuing 'make' in the build
directory if no build targets are specified, which prompts the build
system to build everything.
If only versioned archives are supplied to a depot function like
'create_tar_from_depot_binaries', the depot/create tool is called
with zero arguments, resulting in a help message. The patch detects
this case and skips the call.
Since unifying the build directories accross architectures, the special
case of the 'linux' platform is no longer needed. Linux can be targeted
from regular CPU-architecture-specific build directories via:
KERNEL=linux BOARD=linux
Fixes#4366
When used by the 'Allocator_avl' the slab allocator's backing store is
dynamically disabled and re-enabled while adding/freeing ranges.
However, during those operations, slab entries can be freed. This,
in turn, can result in the release of a slab block (when the freed slab
entry happens to be the last entry of the block). In this corner case,
'Slab::_release_backing_store' operation has no effect because no
backing-store allocator is set. As a result, the block is no longer
referenced but not physically freed.
The patch fixes the problem by skipping '_free_curr_sb' whenever
no backing store is defined. So the completely empty block remains
in the working set.
Thanks to Peter for reporting and fixing this issue!
Fixes#4367
- Consider 'sdl' as source of input events in the event-filter
configuration as generated by the sculpt manager
- Supply an artificial 'platform_info' ROM as requested by the
sculpt manager to obtain the affinity-space information
- Substitute 'fs_rom' for 'cached_fs_rom' as a workaround for the
lack of support for managed dataspaces on Linux
Fixes#4362
This change keeps the version-controlled 'pubkey' and 'download' files
separate from files generated via depot/create or downloaded via
depot/download. So one can remove the entire depot/ directory without
interfering with git.
Furthermore, depot keys can now be hosted in supplemental repositories
independent from Genode's main repository.
Fixes#4364
Fix some trivial cases where the signedness of the constant value does
not match the signedness of type the code expects to see. GCC can be
asked to warn about those by passing Wsign-covnersion flag.
Issue #4354
This comes up when building the code with clang 13. It happens due to
recently enabled Wconversion warning, which in case of clang also
enables implicit-int-conversion warning. The warning reads:
fs_file_system.h:937:44: error: higher order bits are zeroes after
implicit conversion [-Werror,-Wimplicit-int-conversion]
::File_system::Watch_handle fs_handle { -1U };
~~~~~~~~~ ^~~
This can be fixed by properly specifying fs_handle value to be of
unsigned long type.
Issue #4354
As far as I can tell this is not raised by any released GCC versions.
Clang 13 on the other hand warns about it due to implicit-int-conversion
warning which is automatically enabled together with Wconversion. The
problem is relatively simple, shifting access_t value does not always
produce result which is also of access_t type. For example, if access_t
is uint16_t, shifting it will produce integer result. This can be
observed even with GCC. Building the following C++ example will fail:
#include <type_traits>
#include <stdint.h>
int test() {
uint16_t a = 0xabcd;
static_assert(std::is_same_v<decltype(a<<1), uint16_t>);
return 0;
}
Changing uint16_t in the static_assert to int, will allow the code to
build.
Make such int to access_t implicit conversion explicit to allow the code
to be compiled with both GCC and clang.
Issue #4354
The path for the `nameserver` file was fixed to `/socket/nameserver`.
So, if the socket directory was configured differing from `/socket`, DNS
did not work. Now the default path for the `nameserver` takes into
account the path configured in the `socket` libc config attribute.

Remove '_expected_offset' check on round trip test from RX packet,
because allocators between RX/TX can have different allocation
strategies. Rely on 'pattern' check for RX packets only.
In loopback server alloc size must match actual packet size.
issue #4312
Override 'try_alloc/free' because ethernet frame headers are 14 bytes
(src/dst mac (12) + ethertype (2)) causing the IP header to be 2 byte
aligned, leading to problems on platforms that require load/store
operations to be naturally aligned when reading, for example, 4 byte IP
addresses. Therefore, we align the allocation to 2 bytes, so the IP
header is aligned to 4.
