The terminal now got a configurable palette for 16 colors (8 normal, 8
bright/bold).
<config>
<palette>
<color index="0" value="#000000"/> <!-- black is real black -->
<color index="8" value="#101010"/> <!-- bright black stands out a bit -->
</palette>
</config>
Note, the old (undocumented) <color index="..." bg="..."> configuration
scheme is no longer supported.
Also, this commit adds a pleasing default palette that ensures
readability of ViM's standard hightlighting.
Fixes#3406
Instead of hosting our outdated own fork, this commit now uses kernkonzept's
nowadays available github source repositories. This hopefully simplifies
updates, or cherry-picking single fixes.
* isatty
For the moment it is not possible to determine if the fd belongs to a
tty. For whatever reasons, the check is done multiple times, e.g.
'tclsh', which will spam the LOG.
* sysctl(HW_FLOATINGPT)
FPU is enabled on all our platforms, so return true.
Fixes#3389.
Start and stop the DHCP state machine as the Nic link-state changes.
Invoke the link state handler during configuration rather than assume
that in the case of a downed link lwIP will defer DHCP until the link
comes up.
Additionally, support static DNS configuration via the "nameserver"
configuration attribute.
Fix#3388
It might happen, in CPU intensive tests (like TCP bulk lxip), or when
printing debugging output after a failed test (as done currently on
staging), that the run script on the host gives up and reboots the
platform too early. Thus, we raise the buffer time. A reboot should
be necessary only in rare cases anyway.
Fixes#3387
On muen, we don't have configured access to wifi so far. Thus, the wifi
driver doesn't come up and we should skip tests using this driver for
the platform.
Fix#3384
On x86 the CPU count is determined through ACPI's MADT by counting the
local APICs reported there. Some platforms report more APICs
than there are actual CPUs. These might be physically disabled CPUs.
Therefore, a check if the LAPIC is actually physically enabled in
hardware fixes this issue.

fixes#3376
Fix initial stack pointer alignment for x86_64 in crt0.s startup code of
bootstrap. SysV ABI states that upon function entry (rsp + 8) % 16 = 0.
There, we have to align the stack to 16 bytes before all 'call'
instruction not 8. Otherwise FPU (GP) exception might be raised later on
because of unaligned FPU accesses.
issue #3365
Since gcc 8.3.0 generates SSE instructions into kernel code, the
kernel itself may raise FPU exceptions and/or corrupt user level FPU
contexts thereby. Both things are not feasible, and therefore, lazy FPU
switching becomes a no go for base-hw because we cannot avoid FPU
instructions because of the entanglement of base-hw, base, and the tool
chain (libgcc_eh.a).
issue #3365
This removes implementations of and also references to anonymous new and
delete operators from the libc implementation. As allocators for
new/delete Libc::Allocator instances are used, which (paradoxically) map
to libc malloc/free.
Also disable TS (task switch) flag in cr0 during kernel initialization,
so FPU faults are not raised. This became necessary since GCC lately
aggressively generates FPU instructions at arbitrary places and also at
early kernel-bootstrapping stages.
fixes#3365
GCC version 7 and above generate calls to __divmoddi for 64bit integer
division on 32-bit. Unfortunately, libgcc liberaries of older compilers
lack this symbol and are still in use by Debian/Ubuntu LTS at least.
* added global offset table relative loading for global symbols
* removed 'initial_sp' and 'initial_x0' because they are currently not
used on this platform. If required they are easy to resurrect.
issue #3260
The libc features support for SOCK_CLOEXEC now which gets set via
the type argument in 'libnl'. Since we are only interested in the
actual type, i.e. if it is SOCK_RAW, just ignore the flags.
Issue #3289.
* Adjust expected pow(-1/1, inf/-inf/nan) output to current libm
behavior (as in FreeBSD, glibc, and OpenLibm) and return 1 on
x86_64/x86_32/arm
* Add 'double float' outputs for ARM which are defined to float
issue #3289
This prevents
error copying "bin/libm.lib.so": no such file or directory
error copying "bin/posix.lib.so": no such file or directory
when running "make run/noux" from an empty build directory.
On some platforms (foc+pbxa9, hw+imx53_qsb_tz, hw+rpi) the default buffer size
is to much for the RAM available on the board. Thus, decrease the buffer size
and therefore the number of polls for these platforms only.
Fixes#3354
Replace the FreeBSD libm with OpenLibm, which is easier to port.
OpenLibm is used by Mirage's freestanding Ocaml runtime (sin POSIX).

Moreover, express current requirement to hw API, which was missing until now.
Originally, in the board-specific build directory of imx53_qsb the
"KERNEL" variable was preset with "hw". Therefore, it was not perceived
that this dependency is required.

This reverts commit 918b9a9fa4.
The Muen debug console buffer was increased by the recent update, which
alleviates the issue with many log messages as in the ieee754 test.
Components like kernel, core, and bootstrap that are built for a
specific board need to reside inside the same architectural dependent
build directory. For instance there are sel4, foc, and hw kernel builds
for imx6q_sabrelite and imx7d_sabre, which have to reside inside the same
arm_v7 build directory.
This commit names those components explicitely, and adapts the run-tool to it.
Fix#3316
When enabling the 'keep_going' config attribute, the component will
carry on in case a child exited with an error. In addition, if the
'restart' attribute is set it will start executing the children from
the beginning.
Previously, only Invalid_dataspace, Region_conflict, and Out_of_ram were
handled for both allocate and attach with the same handlers. However,
both operations can also throw Out_of_caps and for all exceptions during
attach, the dataspace must be freed again whereas this is not the case
when the exception occured during allocate.

either
- due to poor signal performance of base platform
- due to being to less prioritized
- due to schedule overload
- due to using time sources of different physical CPUs
Issue #3111
Instead of retieving the information about the underlying platform from
the configuration, check the running kernel from the platform_info. This
commit removes the undocumented "acpi" config attribute.
- kernel: propagate cr0 to VMM on exit in nested paging case
- kernel: disable forceful VM exit on task switch
- vm_session: adjust to kernel changes

When there are too many PCI devices, the Expanding_reporter regenerates
the report. However, this doesn't reset the BDF counter used to iterate
over the devices. This results in starting the new report after the PCI
device that triggered the report buffer overflow. This commit fixes the
issue by putting the BDF counter initialization inside the lambda
function used to generate the report.
Fixes#3317
This patch fixes the corner case where an animated geometry changes its
destination mid-way while an animation is already in progress. The
'_trigger_animated_geometry' method used to back out early in this case,
which was intended as an optimization.
Fixes#3296
To enable the use of uncached DMA buffers as RX and TX communication
buffers in between driver (service) and client, introduce a cache
attribute in the constructor of Nic::Session_component
Ref #3291
With the new fact that plain time values are always 64 bit unsigned, the
timestamp type is never bigger than the plain time type. Therefore, a code path
in the curr_time interpolation that treated this condition is not neccessary
anymore.
Ref #3208
This enforces the use of unsigned 64-bit values for time in the duration type,
the timeout framework, the timer session, the userland timer-drivers, and the
alarm framework on all platforms. The commit also adapts the code that uses
these tools accross all basic repositories (base, base-*, os. gems, libports,
ports, dde_*) to use unsigned 64-bit values for time as well as far as this
does not imply profound modifications.
Fixes#3208
