Previously we had configured the timer for the Panda ES with 700 MHz
CPU clock. But the Panda A6 that we use as reference now runs with
800 MHz.
Fixes#2308
Previously, on X86, the timer driver used the PIT with a maximum timeout
of 54 ms. Thus, the driver frequently interrupted the counters with
highest priority to update the timer. This is why we needed a higher
error tolerance as for ARM where the driver, once configured, can sleep
for the whole test timeout. Now, we use the kernel timer and the problem
seems to be exits no longer.
Ref #2304
Previously we pre-calculated the translation errors for the session
quota to make a discret check in the test. But since the order, in which
init childs get their CPU quota isn't always the same anymore (we should
have never made assumptions about that) the translation errors differ
from trial to trial. However, the errors are below 0.01% of the super
period. We now tolerate them in the run script.
Ref #2304
We call curl a second time if the first check fails. This gives download
sites time to reconsider their response and helps, for example, to check
the qemu-usb port.
By separating the plain MMIO access implementation from the generic bit
and offset logic of registers, we can now use the latter also with other
types of register access like I2C. The register and MMIO front-ends have
not changed due to the separation.
Ref #2196
* Acknowledge receive of page-fault signal with ack_signal,
but restart thread execution separately
* use kill_signal_context when disolving a pager_object to prevent race
* Remove bureaucracy in form of Thread_event and Signal_ack_handler
* remove dead code in riscv, namely Thread_base definition
* translation_table_insertions function for ARM drops out,
which was overcautious
The MIN_PSK_LENGTH constant was not adjusted to accommodate for the
semcantic change when switching from using the raw char array to using
the Genode::String class. The Genode::String::length() method includes
the terminating NUL byte while strlen() does not.
Fixes#2296.
With the commit "init: session-label rewriting", the stack usage
increased due to the handling of session-label strings as local
variables. The stack overrun occurred in the vmm scenario on
base-hw.
