9f8ccc030b linux.port: add usb_net_cdc_ncm.patch
NCM tries to batch TX packets using timeouts (500us) and does not send packets
before 3 packets are in the submit queue. Timeouts take milliseconds on
dde_linux which leads to delayed ACKs and poor performance for the RX case.
Therefore, we send small packets (<100 Bytes) immediately without batching (it
might be an ACK or last packet of a larger transfer).

b587134a8d net tests: raise nic_drv/drivers cap quota
Several nightly network-related tests fail currently on sel4/pc because the
new e1000 NIC driver requires more capabilities. The "drivers nic" package
was already adapted to the new requirement but some tests fail to provide
enough caps to the corresponding sub system. This commit tries to fix all
remaining tests.

4277bdd3cd lx_emul usb: solve session close races
* During a session-close, the device-specific usb task and driver data
  gets freed. Part of it was the RPC data. To prevent use-after-free
  turn it into a pointer and leave it on the stack of the caller thread
* During a device release, URBs discards, and reset operation the Linux task
  might get blocked, and then a RPC caller task might return if the RPC
  operation was marked as finished already, although it hasn't succeeded yet
* USB devio RESET has to be done before a device release to be effective

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.

dd1b8a106f drivers/wifi: perform multi-staged construction
Since the wireless LAN driver is actually a 'Libc::Component' due to
its incorporation of the 'wpa_spplicant' application, we have to
intercept its construction because we have to initialize the Lx_kit
environment before any static ctors are executed. Most Linux initcalls
are implemented as ctors that will be otherwise implicitly executed
before the controll is given to us in 'Libc::Component::construct'.

1cac134030 lx_kit: support multiple pending IRQs
Decoupling the scheduler execution can lead to missed interrupts
because the current implementation only handles one pending
interrupt and requires immediate processing.

This commit introduces a helper object that is used to capture
any occuring interrupts that are then handled consecutively.

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.

dc178e0ab2 dde_linux: enhance KBUILD_MODNAME generation
It turns out solely relying on the name of the compilation-unit
is not enough. In at least one multi-device driver, e.g. rtlwifi,
an equally called compilation-unit is found in several different
directories. There KBUILD_MODNAME is used to name the driver,
which fails later on as the driver framework refuses to register
an equally named driver twice.

Instead of only considering the name of the compilation-unit also
include the last element of the path to generate differentiating
KBUILD_MODNAME value.

d5710d9de3 Move 'wifi' driver to dde_linux repository
The bulk of the driver code now lives in the 'dde_linux' repository,
which is available on all platforms, from where it can be referenced by
other repositories.

The 'wifi_drv' binary was delegated to a generic harness that includes
all configuration and management functionality shared by all wireless
device driver components, e.g., the wpa_supplicant. The code of the
device driver emulation environment is located in 'src/lib/wifi'. It
is referenced by the platform-specific driver library that resides in
the corresponding platform repository. The runtime configuration needs
to point the driver to proper driver library.

The platform-specific library is in charge of orchestrating the contrib
source utilized by the driver as well as providing the 'source.list'
and 'dep.list' files. It must include the generic library snippet
'repos/dde_linux/lib/wifi.inc' that deals with managing the emulation
environment code.

The 'repos/dde_linux/src/drivers/wifi/README' file contains more
detailed information on how to deploy the driver.

6a7a30ceaa lx_emul: unify udelay implementation
Implement udelay for all architectures within common lx_emul code,
remove driver-specific version.

Always do busy looping in udelay and use cpu_relax()
like the original Linux code. Thereby, we profit from architecture specific
instructions (cpu cool down), and jiffies are updated if irqs are on.

50541c68ec lx_emul: shadow cpu_relax to update jiffies
There are rare use-cases where cpu_relax is used inside a busy loop
(i2c bus functions), which only will break when the jiffies counter
reaches a specific value.
Because of the cooperative scheduling done in lx_emul, no timer
interrupt will break such a loop. As a workaround, we check for
necessary jiffies updates inside cpu_relax if interrupts are enabled.

e2c334d6e4 linux: allow more workers when scheduling works
Workers are only summoned by the manager or when there are no workers on
a work queue. In case a work in front of a work queue depends on a work
behind it, a deadlock may occur. To solve this Linux spawns a rescue
worker using timers. Timing of Linux based drivers is currently reworked
and not reliable. Therefore, we increase the number of workers that are
spawned from 1 to 3 per work queue in order to resolve possible
deadlocks.

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'.

578a8c9918 wifi/pc: add rtlwifi driver
Due to lacking hardware access the driver was test with one RTL8188EE
based device, namely [10ec:8179] (rev 01), only. As the access to the
PCI config space is restricted the driver loads the non power-saving
FW and the driver port is therefor only tested with that. The
accesses are documented should we choose to support them one way or
another later on.

The 'wifi.run' run script as well as Sculpt served as testing ground
where the driver worked fine so far.

d33139c40a enable ccache for reference Linux kernel
Genode build system allows to easily enable 'ccache' for builds. This
change allows to enable using 'ccache' also for build of reference
Linux kernel used during porting device drivers.

To enable 'ccache' it is enough to pass value of 'CC' variable when
executing Linux build but this build by default depends on time when it
is built which causes 'ccache' misses. To solve this issue additional
flags are passed to make build independent from time, current user and
host on which build is performed.

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.
