This recipe copies the entire stdcxx library into the API archive, which
is an interim solution until we introduce a proper ABI for stdcxx. With
this current version, every user of the stdcxx ABI will implicitly build
the stdcxx library.
This patch merges two similar rules, which create content at 'include'
into a single rule. This prevents a possible race condition when
creating archives in parallel.
We moved the stack-area segment 128 MiB behind text and data to comply
with assumptions in the kernel ELF loader.
This commit also reenables static binaries on linux and removes the
unused stack_area.stdlib.ld script.
Fixes#2521
This is a drivers subsystem that starts the most fundamental
(framebuffer, input, block) device drivers dynamically, depending on the
runtime-detected devices. The discovered block devices are reported
as a "block_devices" report.
This patch applies the handling of cursor keys, function keys, and page
up/down keys even if no keymap is defined. This is the case when using
the terminal with character events produced by the input filter.
This patch is a workaround for the apparent problem that noux
applications, which perform execve, implicitly use functionality from
the dynamic linker, not explicitly via the libc. If the binary lacks the
dependency information, noux will fail on the execve attempt. The latter
is the case when the noux package is built as a depot archive where
library dependencies are not traversed over multiple levels.
In nested scenarios like driver_manager.run, the initial session quota
for IO_PORT, IO_PORT, and IRQ sessions is expectedly insufficient.
However, the condition is properly handled by re-attemping the request
with a slightly increased quota. Still, core prints a warning each time
the request is denied for quota reasons, which spams the log. This patch
removes the non-critical message.
Create periodic and one-shot timeouts with the maximum duration
to see if triggers any corner-case bugs. They must not trigger during
the test.
Ref #2490
If we add an absolute timeout to the back-end alarm-scheduler we must first
call 'handle' at the scheduler to update its internal time value.
Otherwise, it might happen that we add a timeout who's deadline is so big that
it normally belongs to the next time-counter period but the scheduler thinks
that it belongs to the current period as its time is older than the one used
to calculate the deadline.
Ref #2490
When we have two time values of an unsigned integer type and we create
the difference and want to know wether it is positive or negative within
the same value we loose at least one half of the value range for casting
to signed integers. This was the case in the alarm scheduler when
checking wether an alarm already triggered. Even worse, we casted from
'unsigned long' to 'signed int' which caused further loss on at least
x86_64. Thus, big timeouts like ~0UL falsely triggered directly.
Now, we use an extra boolean value to remember in which period of the
time counter we are and to which period of the time counter the deadline
of an alarm belongs. This boolean switches its value each time the time
counter wraps. This way, we can avoid any casting by checking wether the
current time is of the same period as the deadline of the alarm that we
inspect. If so, the alarm is pending if "current time >= alarm
deadline", otherwise it is pending if "current time < alarm deadline".
Ref #2490
If the PIT timer driver gets activated too slow (e.g. because of a bad priority
configuration), it might miss counter wraps and would than produce sudden time
jumps. The driver now detects this problem dynamically, warns about it and
adapts the affected values to avoid time jumps.
