9b5944b90c platform_drv: use IOMMU devices
Every session component manages a registry of Io_mmu::Domain objects
that it creates on demand depending on the acquired devices (i.e. the
IOMMU devices referenced by the acquired devices). Via the domain
objects, a session component adds/removes the address ranges of the
allocated DMA buffers. Additionally, domain objects provide an interface
for enabling/disabling pci devices.

Domain objects get destroyed with the corresponding control device.
Moreover, on devices/policy ROM updates, domain objects of control
devices that are not referenced by any acquired device anymore get destroyed.

b2e4f95f27 platform_drv: add <io_mmu> to devices ROM
This allows referencing an arbitrary number of IOMMU devices within a
<devices> node, e.g.:

<device>
  <io_mmu name="foobar"/>
</device>

The specified name is supposed to refer to an existing device in the
devices ROM. The platform driver automatically acquires known IOMMU
devices whenever they become available so that the device object can be
looked up from the platform-driver-owned devices.

ae0e0c118e nvme_drv: add support for host-memory-buffer
This commit introduces support for the HMB feature and will setup the
buffer during start-up. The host-memory-buffer (HMB) feature is mostly
used on NVMe devices that do not make use of an DRAM cache to store its
translation tables amongst other operational data. Not using HMB can
impair the performance on such devices.

The memory is allocated in 2 MiB chunks of DMA-capable memory and its
total size in bytes is configurable via the 'hmb_size' config attribute.
The driver always checks the minimal and preferred size of the HMB and
issues a warning in case it is not enabled via the configuration.
Moreover, if the configured size is less than the minimal amount
required by the device the HMB is not configured at all and a warning
is issued also. If the configured size is more than the preferred size
it will be capped to that amount.

bdf47785b8 vfs: remove 'file_size' from read/write interfaces
The 'file_size' type denotes the size of files on disk in bytes. On
32-bit architectures it is larger than the size_t, which refers to
in-memory object sizes.

Whereas the use of 'file_size' is appropriate for ftruncate and seek, it
is not a suitable type for the parameters of read/write operations
because those operations refer to in-memory buffers.

This patch replaces the use of 'file_size' by size_t. However, since it
affects all sites where the read/write interface is uses, it takes the
opportunity to replace the C-style (pointer, size) arguments by
'Byte_range_ptr' and 'Const_byte_range_ptr'.

3260c86d15 gpu_session: VRAM interface
Change the abstraction from buffers to video RAM (VRAM). The notion of
buffers can be provided at the client side (e.g., Mesa) and multiple
buffers can be there be associated to one VRAM area, thus saving
resources (meta data overhead) when allocating many buffers. A VRAM area
can also be mapped to one single buffer as before for clients or drivers
that do not take advantage of this feature.

61a7671de1 os/vfs.h: read loop in Readonly_file::read
This patch improves the Readonly_file::read method such that the
capacity of the specified buffer is used as upper bound for the read
operation instead of VFS-internal I/O buffer sizes. This relieves the
caller from implementing a read loop in most cases.

As a step away from C-ish use of the API, the patch deprecates the old
'read' method that takes the buffer as char *, size_t arguments.

  transport-routing rules only with transport-routing rules. Besides raising
  the performance of the code, this also fixes a former bug that allowed
  forward-rule links to falsely stay active because of a transport-routing
  rule that matched the client destination ip and port.

* Don't use good-case exceptions for updating TCP/UDP links on re-configuration
  of the router.

* Make conditions when to dismiss a forward rule easier to read.
  * Introduces != operator to the public Port class in the net library.

* Fix unnecessary log message that a link was dismissed when only a potentially
  matching forward rule turned out to be not matching.

* Apply Genode coding style to if statements with a single body statement.

1b1a9ca95c nic_router: fix bad connection states on IP change
When a domain receives a new dynamic router IP address and that domain has
active connection states (TCP/UDP/ICMP) from another domain with NAT applied,
the connection states used to stay active while becoming obsolete. They
become obsolete because their identification and their packet processor
use the old routers IP address due to NAT.

One consequence was that connections became dysfunctional when the server
domain received a new dynamic router IP address. Request packets were still
routed from client to server, but when entering the server, their source IP
address was the outdated router address. Consequently, the server responses
used the outdated address as destination and the router dropped the responses
because it did not know this address anymore.

This commit fixes the problem by letting a domain destroy all its connection
states that were initiated from within other domains whenever it detaches from
its current IP configuration.

Strictly speaking, it is not necessary to destroy all connection states, only
those that the domain applies NAT to. However, the Genode AVL tree is not built
for removing a selection of nodes and trying to do it anyways is complicated.
So, for now, we simply destroy all connection states.

Note that the other way around was handled correctly already. When a domain
detaches from its IP config, all interfaces of that domain destroy all the
connection states they created (towards other domains).

ff2176a586 vfs,libc: support write fds in select
By adding a 'write_ready' interface following the lines of the existing
'read_ready', VFS plugins become able to propagate the (de-)saturation
of I/O buffers to the VFS user. This information is important when using
a non-blocking file descriptor for writing into a TCP socket. Once the
application observes EAGAIN, it expects a subsequent 'select' call to
return as soon as new I/O buffer space becomes available.

Before this patch, the select call would always return under this
condition, causing an unnecessarily busy write loop.

7d8d4f4532 vfs,libc: deferred wakeup of remote peers
This patch facilitates the batching of I/O operations in the VFS library
by replacing the implicit wakeup of remote peer (via the traditional
packet-stream interface like 'submit_packet') by explicit wakeup
signalling.

The wakeup signalling is triggered not before the VFS user settles down.
E.g., for libc-based applications, this is the case if the libc goes
idle, waiting for external I/O.
In the case of a busy writer to a non-blocking file descriptor or socket
(e.g., lighttpd), the remote peers are woken up once a write operation
yields an out-count of 0.

The deferring of wakeup signals is accommodated by the new 'Remote_io'
mechanism (vfs/remote_io.h) that is designated to be used by all VFS
plugins that interact with asynchronous Genode services for I/O.

49b4b8597d os/pin_driver: support for time-multiplexed in/out
This patch equips the pin-driver framework with support for the
time-multiplexed operation of a pin as output or input. This is needed
when implementing I2C communication via a bit-banging driver.

To operate pin in both directions, a driver obtains both a pin-state and
a pin-control session for the same pin. The pin-state session can be
used to sense the current pin state. The control session allows the
client to set the pin to high or low (using the 'state' method), or to
set it to high-impedance via the 'yield' method. Once switched to
high-impedance, the pin can be used as input.

a420670217 pci_decode: disable MSI on HDAUDIO cards
According to OpenBSD's azalia driver some AMD HDAudio devices do not
play nice with MSIs although the capability is set. At least the
0x1457 device was tested and worked using GSIs only.

c83f307b62 nic_router: consider DHCP client optimization
Some DHCP clients (Debian VM in Sculpt) persistently store the last lease they
obtained and try to directly DHCP REQUEST it on a new startup whithout doing
DHCP DISCOVER beforehand. In case the NIC router doesn't know about the lease
anymore (timeout, new router instance), the router used to just ignore the DHCP
REQUEST. This led to significant delays in the network startup of the client
(delayed retries until give-up and DHCP DISCOVER). With this commit, the router
answers such packets with a DHCP NAK instead, causing the client to directly
switch to DHCP DISCOVER.

e7ba0b7371 pci: initialize BAR config on demand only
On-demand initialization prevents read-write operations on BARs of
invalid devices at construction time, which may result in surprising
behavior later on, for example, when resetting X260 notebooks via ACPI
information.

eb6a745a18 platform: add Guard utils for Clock/Reset/Power
These utilities simplify the control of clocks, resets, and power
domains from within the platform driver.

This is needed when driving a low-level device directly from the
platform driver, for example for driving the mbox mechanism to access
the system-control processor of the PinePhone.

243c819257 pci_decode: use MSI enumerator as function value
Instead of using a global value to enumerate the MSIs, use a function argument
instead. Whenever the process of PCI device reporting gets started again,
due to an initially too small report buffer, the MSI enumeration value is reset
again. Formerly, we wasted MSI numbers.

6a7247ab44 platform: remove cache attribute from io_mem call
Instead of allowing the client to set a caching attribute
in the io_mem() call of the device interface, which was
only used to decide in between of the memory  being
write-combined or not, remove it from the API.
Instead use the information delivered by the devices ROM,
whether memory from a PCI BAR is prefetchable or not,
to decide whether it is mapped write-combined or not.

f59ee209d2 nic_router: use exact packet sizes in dhcp client
The DHCP client used to always send packets with a size of 1024 regardless of
the size of the actual content, which was always significantly lower. 1024
bytes was simply a guess to provide enough space for all types of DHCP client
packets. As we know the exact size of each packet the DHCP client sends even
before packet creation, this commit makes use of the knowledge resulting in
much smaller packets sent by the DHCP client.
