This patch moves the implementation of the 'Arm::memory_region_attr'
function from the generic ARM code to the ARM v6/v7 specific code
to enable the customization of page-table bits depending on the
specific CPU core type. I.e., the ARM1176 apparently does not cope
well with setting the 'Tex::bits(2)' for MMIO mappings.
This patch eliminates calls of 'cmpxchg' prior enabling the MMU. This is
needed because the 'ldrex' and 'strex' instructions do not always work
with MMU and L1 cache disabled, i.e., on Raspberry Pi.
Changes GPIO session interface to a one-GPIO-pin-per-session style. Moreover,
this commit introduces a generic driver interface for GPIO drivers. Thereby
generalizes root- and session component for GPIO.
In issue #313 the SO_RCVBUF was intended to be enabled, however the current
lwip port looks for another define LWIP_SO_RCVBUF instead of LWIP_RCVBUF.
Fixes#716
If the target machine is connected locally one may specify
"serial" as target in the RUN_OPT variable to get the test output.
Used for panda and arndale on foc and hw.
Use RUN_OPT="--target ..." to select the backend test method.
Supported values so far:
qemu - qemu + grub bootloader (default)
qemu+pxe - qemu + pulsar bootloader (PXE)
amt - Intel AMT (reset+serial output) + pulsar bootloader

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.
genode_until_run can be called now with a spawn id to able to reattach to a
spawned process (amt, serial output). Run scripts can now call genode_until_run
multiple times.
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.
lwIP only supports the 'AF_INET' domain, but doesn't check the 'domain'
argument of the 'lwip_socket()' function.
This patch avoids an error message from lwIP when the Arora browser
tries to connect a socket of the 'AF_LOCAL' domain.
Fixes#732.
The parent-service registry is populated on demand by the
'Loader::Child' whenever a prior unknown service is requested. Since the
number of parent services is limited, we expect the registry to settle
after a while. However, each loader session has a private instance of
a parent-service registry. So when creating and destroying loader
sessions, parent registries will be populated again and again. We
have to make sure to discard the entries along with the destruction
of a loader session to avoid the leakage of memory.
