c767f6ccf1 os: explicit cache policy in Nic::Session_component
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

5ca30b0318 platform_drv: disable PCI DMA class specific
for such classes where it should be safe and where we have seen issues.
Disabling in general bus master DMA causes on some machines hard hangs, e.g.
because the USB handover protocol was violated.

136b23cb5e ipxe nic_drv: do not leak packets on link down/up
On link down toggle the netdev off/on to drain the TX DMA. As long as the link
stays down, do not write packets to TX DMA.

366bba0227 Exclude higher-level repos from strict warnings
This is a follow-up commit to "Increase default warning level", which
overrides Genode's new default warning level for targets contained in
higher-level repositories. By explicitly whitelisting all those targets,
we can selectively adjust them to the new strictness over time - by
looking out for 'CC_CXX_WARN_STRICT' in the target description files.

4d442bca30 Streamline exception types
This patch reduces the number of exception types by facilitating
globally defined exceptions for common usage patterns shared by most
services. In particular, RPC functions that demand a session-resource
upgrade not longer reflect this condition via a session-specific
exception but via the 'Out_of_ram' or 'Out_of_caps' types.

Furthermore, the 'Parent::Service_denied', 'Parent::Unavailable',
'Root::Invalid_args', 'Root::Unavailable', 'Service::Invalid_args',
'Service::Unavailable', and 'Local_service::Factory::Denied' types have
been replaced by the single 'Service_denied' exception type defined in
'session/session.h'.

This consolidation eases the error handling (there are fewer exceptions
to handle), alleviates the need to convert exceptions along the
session-creation call chain, and avoids possible aliasing problems
(catching the wrong type with the same name but living in a different
scope).

cb43e04691 ldso: defer execution of static constructors
Ldso now does not automatically execute static constructors of the
binary and shared libraries the binary depends on. If static
construction is required (e.g., if a shared library with constructor is
used or a compilation unit contains global statics) the component needs
to execute the constructors explicitly in Component::construct() via
Genode::Env::exec_static_constructors().

In the case of libc components this is done by the libc startup code
(i.e., the Component::construct() implementation in the libc).

The loading of shared objects at runtime is not affected by this change
and constructors of those objects are executed immediately.

15821e32ec nic: remove usage of deprecated env()
This commit includes changes to the Nic::Session_component interface.
We now pass the entire env to the component instead of only ram, rm and
the ep because we need the env to open connections from within the
Session_component implemenation. So far only the cadence_gem driver
needs this, though.

17c79a9e23 base: avoid use of deprecated base/printf.h
Besides adapting the components to the use of base/log.h, the patch
cleans up a few base headers, i.e., it removes unused includes from
root/component.h, specifically base/heap.h and
ram_session/ram_session.h. Hence, components that relied on the implicit
inclusion of those headers have to manually include those headers now.

While adjusting the log messages, I repeatedly stumbled over the problem
that printing char * arguments is ambiguous. It is unclear whether to
print the argument as pointer or null-terminated string. To overcome
this problem, the patch introduces a new type 'Cstring' that allows the
caller to express that the argument should be handled as null-terminated
string. As a nice side effect, with this type in place, the optional len
argument of the 'String' class could be removed. Instead of supplying a
pair of (char const *, size_t), the constructor accepts a 'Cstring'.
This, in turn, clears the way let the 'String' constructor use the new
output mechanism to assemble a string from multiple arguments (and
thereby getting rid of snprintf within Genode in the near future).

To enforce the explicit resolution of the char * ambiguity, the 'char *'
overload of the 'print' function is marked as deleted.

511acad507 Consolidate RM service into PD session
This patch integrates three region maps into each PD session to
reduce the session overhead and to simplify the PD creation procedure.
Please refer to the issue cited below for an elaborative discussion.

Note the API change:

With this patch, the semantics of core's RM service have changed. Now,
the service is merely a tool for creating and destroying managed
dataspaces, which are rarely needed. Regular components no longer need a
RM session. For this reason, the corresponding argument for the
'Process' and 'Child' constructors has been removed.

The former interface of the 'Rm_session' is not named 'Region_map'. As a
minor refinement, the 'Fault_type' enum values are now part of the
'Region_map::State' struct.

463c9bec17 Replace Nic driver interface by customizable component
Removed the Nic::Driver implementation. All nic servers now inherit from
Nic::Session_component. Packet stream signals are dispatched to
the 'handle_packet_stream' function within a session component. Thus, nic
servers now have direct access to the packet stream channels, making handling
more flexible.

Adjusted nic_loobpack, dde_ipxe, wifi, usb, lan9118, Linux nic, and OpenVPN to
the new interface.

9606abc146 dde_ipxe: remove dde_kit
A long long time ago, in a galaxy^W^W^W we used DDE kit to ease the
porting of purely C based drivers. By now it became clear, that we
do not gain that much by following this approach. DDE kit contains
much generic functionality, which is not used or rather not needed
by most ported drivers. Hence, we implement a slim C wrapper on top
of Genode's C++ APIs, that is especially tailored to the driver.

In addition to removing the dependency on DDE kit, the iPXE driver
now uses the server framework and the newly introduced signal based
IRQ handling.

dd47129bef nic session: link-state change handling
A Nic::Session client can install a signal handler that is used to
propagate changes of the link-state by calling 'link_state_sigh()'.
The actual link state is queried via 'link_state()'.

The nic-driver interface now provides a Driver_notification callback,
which is used to forward link-state changes from the driver to the
Nic::Session_component.

The following drivers now provide real link state: dde_ipxe, nic_bridge,
and usb_drv. Currently, OpenVPN, Linux nic_drv, and lan9118 do not
support link state and always report link up.
