14b3a0c794 platform/pc: support poweroff
If the support for S5 is announced via the sleep_state report, the
pc_platform_drv now issues the S5 (poweroff) via Pd::system_control.

4c79f948ab platform/pc: support to suspend via system_control
When the "system" ROM state turns to "suspend",
the S3 state information of the sleep_states ROM are determined and
are used to invoke the privileged Pd::system_control call.

5dce61563e pc_intel_fb: configure max framebuffer memory
This commit introduces the means to configure the framebuffer memory
used by the driver for sizing its buffers.

Originally the avail memory was derived from the avail ram in the PD
session, which roughly corresponds to configured RAM quota.
However, since it is only used in a virtual capacity, we can decouple
it from the actual memory and set to a value that accommodates larger
framebuffer resolutions like 3840x2160. If the configured RAM quota
is not enough to satisfy an allocation request the client will issue
a resource request.

fd60e5a8b2 pc_wifi: provide iwlwifi LED related dummies
These generated dummies slipped in when the commit
'pc_linux: enable gpio, audio' got merged and mainly concern old devices
from the 6xxx series.

The functions are normally guarded via 'CONFIG_IWLWIFI_LEDS' but due to
the olddefconfig step when generating our pc_linux config using
LX_DISABLE has no effect.

9971f41f8c platform/pc: fix IOMMU fault reporting
When the kernel does interrupt remapping, we cannot get a non-remapped MSI
for fault event interrupts. We therefore let the kernel do the fault
reporting in this case.

68925a6d33 pc/lx_emul: enable HIGH_RES_TIMERS
Only with high-resolution timers enabled timouts can fire between two
jiffies. The option is enabled on all relevant platforms but
unfortunately disabled by tinyconfig.

This option also permits the use of CONFIG_SND_HRTIMER.

7ec08af6d9 usb: session renewal & new client API
Replace the USB session API by one that provides a devices ROM only,
which contains information about all USB devices available for this client,
as well as methods to acquire and release a single device.

The acquisition of an USB device returns the capability to a device session
that includes a packet stream buffer to communicate control transfers
in between the client and the USB host controller driver. Moreover,
additional methods to acquire and release an USB interface can be used.

The acquisition of an USB interface returns the capability to an interface
session that includes a packet stream buffer to communicate either
bulk, interrupt, or isochronous transfers in between the client and the
USB host controller driver.

This commit implements the API changes in behalf of the Genode C API's
USB server and client side. Addtionally, it provides Usb::Device,
Usb::Interface, and Usb::Endpoint utilities that can be used by native
C++ clients to use the new API and hide the sophisticated packet stream API.

The adaptations necessary target the following areas:

* lx_emul layer for USB host and client side
* Linux USB host controller driver port for PC
* Linux USB client ports: usb_hid_drv and usb_net_drv, additionally
  reduce the Linux tasks used inside these drivers
* Native usb_block_drv
* black_hole component
* Port of libusb, including smartcard and usb_webcam driver depending on it
* Port of Qemu XHCI model library, including vbox5 & vbox6 depending on it
* Adapt all run-scripts and drivers_interactive recipes to work
  with the new policy rules of the USB host controller driver

1336b0a751 mmio: upper-bounds checks
The classes Genode::Mmio, Genode::Register_set, Genode::Attached_mmio, and
Platform::Device::Mmio now receive a template parameter 'size_t SIZE'. In each
type that derives from one of these classes, it is now statically checked that
the range of each Genode::Register::Register- and
Genode::Register_set::Register_array-deriving sub-type is within [0..SIZE).

That said, SIZE is the minimum size of the memory region provided to the above
mentioned Mmio classes in order to avoid page faults or memory corruption when
accessing the registers and register arrays declared inside.

Note, that the range end of a register array is not the end of the last item
but the end of integer access that is used for accessing the last bit in the
last item.

The constructors of Genode::Mmio, Genode::Attached_mmio, and
Platform::Device::Mmio now receive an argument 'Byte_range_ptr range' that is
expected to be the range of the backing memory region. In each type that derives
from on of these classes, it is now dynamically checked that 'range.num_bytes
>= SIZE', thereby implementing the above mention protection against page faults
and memory corruption.

The rest of the commit adapts the code throughout the Genode Labs repositories
regarding the changes. Note that for that code inside Core, the commits mostly
uses a simplified approach by constructing MMIO objects with range
[base..base+SIZE) and not with a mapping- or specification-related range size.
This should be fixed in the future.

Furthermore, there are types that derive from an MMIO class but don't declare
any registers or register arrays (especially with Platform::Device::Mmio). In
this case SIZE is set to 0. This way, the parameters must be actively corrected
by someone who later wants to add registers or register arrays, plus the places
can be easily found by grep'ing for Mmio<0>.

1e7116fcc1 lx_emul: manage page structs per buffer range
The management of Linux page structs is now tied to the life time of DMA
buffers. Thus, page structs are created when a buffer is allocated and
deallocated only when a buffer is freed - not on lx_emul_mem_free()
because DMA buffers are cached. Page struct refcounting was entirely
reworked in lx_emul/shadow/mm/page_alloc.c.

342e48115e lx_emul: replace USB devio API usage
The devio API in the Linux kernel promised to be a stable layer for our
USB host controller drivers, but the additional bookkeeping and dynamic
allocations increase CPU overhead in a way that we do not accept further.
Therefore, we go a step back and process DMA transactions directly in and
out of the packet stream from the clients.

e18c02991e lx_kit: use central signal handler for scheduling
This commit extends the Lx_kit initialization function by passing in
a signal handler that is used to perform the normally occurring
scheduler execution and is a follow-up change for the decoupling
scheduler execution commit.

Instead of burying the signal handler in the 'Lx_kit::Scheduler'
object it is provided by the main object where the driver is free
to perform any additional step before or after executing the scheduler.

caac994da8 lx_kit: decouple schedule execution
Prior to this commit, whenever an external event occurred, for example
timer or interrupt, the corresponding I/O signal handler was triggered.
This handler unblocked the task waiting for the event and initiated the
immediate execution of all unblocked tasks. Since these tasks may hit
serialization points, e.g. synchronously waiting for packet stream
operations, that require handling of other I/O signals this leads to
nested execution. This, however, is not supported and mixes application
and I/O level signal handling.

The flagging of the scheduling intent is now decoupled from its
execution by using an application level signal handler that is run in
the context of the components main entrypoint. The I/O signal handler
now triggers the scheduling execution by sending a local signal to
the EP.

Since it might be necessary to execute a pending schedule from the EP
directly the scheduler is extended with the 'execute' member function
that performs the check that the scheduler is called from within the
EP and triggers the execution afterwards.

afaabb3121 pc_nic_drv: add R8169 driver
This commits enables the R8169 driver and was tested with two
RTL8168h/8111h (10ec:8168 rev 0x15 sub 1462:7a38 / 1d05:109f) and
two equal RTL8125B (10ec:8125 rev 0x5 sub 1458:e000) devices
running Sculpt.

Firmware loading is for now not implemented but specific Linux
commits suggest it could be necessary. However, doing so will be
post-poned until we have gathered more experience with the driver.

Restarting the driver might lead to the following IOMMU error
messages but the device seems to work anyway:
