This patch updates the launchpad config to use XML attributes and
removes the built-in default configuration (which is only meaningful
for demo.run anyway).
To raise expressiveness of the benchmark it dynamically adjusts the
transfer amount at any test to get a result that was measured
over a transfer time of 2000 ms at least and 2300 ms at a max.
* Implements platform driver for Arndale providing Regulator for CPU clock
* Implements a cpu frequency scaling test using the affinity test
* Fixes#770
A run script which sends raw ethernet packets from the host machine to the
target machine. Three tests are implemented:
- The network_stat instrumented driver of usb_drv and net_drv
are used to get the raw receive performance of the network driver.
- A simple nic_session client is receiving from the un-instrumented network
driver raw ethernet packets.
- A bridge is added between driver and simple nic_session client.
Additionally, we do the cleanup of the remains of a previously failed
run prior creating the run directory. Otherwise, the directly creation
may fail because of a pending bindmount.
With this patch, the thread context area RM session gets created at
program startup to have the thread context area's virtual address range
reserved right from the beginning.
Fixes#734.
This patch implies that all Genode processes try to create an RM
session. So a route to the RM service must be present even for processes
that have only a single thread. Hence, the patch contains an update of
affected components.
The KDB UART driver uses the Fiasco(.OC) kernel debugger console as backend
for input and output. This is useful in the case that only one UART is
available.
Fixes#665.
This patch moves the os/config examples to their respective run scripts,
removes some of them, and moves the priority example to the src/init
directory (where other examples are located).
Additionally, this patch adapts the OKL4-specific priority.run test to
the recent changes of the timer interface.
The 'Timer::Session::msleep' function is one of the last occurrences of
long-blocking RPC calls. Synchronous blocking RPC interfaces turned out
to be constant source of trouble and code complexity. I.e., a timer
client that also wants to respond to non-timer events was forced to be a
multi-threaded process. This patch replaces the blocking 'msleep' call
by a mechanism for programming timeouts and receiving wakeup signals in
an asynchronous fashion. Thereby signals originating from the timer can
be handled along with signals from other signal sources by a single
thread.
The changed interface has been tested on Linux, L4/Fiasco, OKL4, NOVA,
L4ka::Pistachio, Codezero, Fiasco.OC, and hw_pbxa9. Furthermore, this
patch adds the timer test to autopilot.
Fixes#1
With this change, init becomes able to respond to config changes by
restarting the scenario with the new config. To make this feature useful
in practice, init must not fail under any circumstances. Even on
conditions that were considered as fatal previously and led to the abort
of init (such as ambiguous names of the children or misconfiguration in
general), init must stay alive and responsive to config changes.
With this patch, the loader installs an optional client-provided fault
handler as default CPU exception handler and RM fault handler for all
CPU and RM sessions of the loaded subsystem. This way, loader clients
become able to respond to failures occuring within the subsystem.
The new feature is provided via the added 'Loader::fault_handler' RPC
function.
The 'run/failsafe' test covers two cases related to the loader, which
are faults produced by the immediate child of the loader and faults
produced by indirect children.
