4506912f6e dde_ipxe: skip MAC/PHY reset on Intel NICs
Inspired by the mailing-list posting [1], this commit removes the
MAC/PHY reset for all Intel cards and effectively prevents the bandwidth
drop to 10 MBit/s (e.g., on i217lm). I understand it as preliminary fix
for practical reasons - a real fix would be to update the ipxe port and
monitor for more postings like the one mentioned.

e233fe0b71 os: add component for filtering USB devices report
The 'usb_report_filter' component takes the devices report from the
USB driver and generates a new devices report after checking each
entry against its device white-list. Before emitting the new report
it changes the configuration of the USB driver to contain the
required policy entries.

See 'repos/os/src/app/usb_report_filter/README' for more details.

c3d4802ac8 hw: re-implement lazy FPU context switch
The new implementation of the FPU and FPU context is taken out to
separate architecture-dependent header files. The generic Cpu_lazy_state
is deleted. There is no hint about the existence of something like an
FPU in the generic non-architexture-dependent code anymore. Instead the
architecture-dependent CPU context of a thread is extended by an FPU
context where supported.

Moreover, the current FPU implementations are enhanced so that threads
that get deleted now release the FPU when still obtaining it.

040cd95580 noux: fix context-area re-initialization in fork
With commit e74b53d5dd the fork semantic in noux
changed slightly, and broke platforms like hw & sel4, where the UTCB is mapped
directly into the thread's context area. The change moved the re-initialization
to a point where the new noux process' thread stack-pointer was already switched
back to the context area. But to re-initialize the context area RPC calls must
be done, and the UTCB must be used therefore. On the other side the UTCB is
found implicitly by the stack-pointer, whereby a stack-pointer located in the
context-area refers to a UTCB that is expected to reside in the context-area
as well. But the UTCB gets overlayed inside the context area by the
context-area's re-initialization - we've come round in a circle.

This commit rolls back the move of the re-initialization routine. To preserve
the intention of the original commit, the context-area location is stored in
a static variable, so that the Native_config API is not needed anymore.

7aff1895bf hw: enable SMP for ARM Cortex A9
This commit enables multi-processing for all Cortex A9 SoCs we currently
support. Moreover, it thereby enables the L2 cache for i.MX6 that was not
enabled until now. However, the QEMU variants hw_pbxa9 and hw_zynq still
only use 1 core, because the busy cpu synchronization used when initializing
multiple Cortex A9 cores leads to horrible boot times on QEMU.

During this work the CPU initialization in general was reworked. From now
on lots of hardware specifics were put into the 'spec' specific files, some
generic hook functions and abstractions thereby were eliminated. This
results to more lean implementations for instance on non-SMP platforms,
or in the x86 case where cache maintainance is a non-issue.

Due to the fact that memory/cache coherency and SMP are closely coupled
on ARM Cortex A9 this commit combines so different aspects.

166672fe16 hw: l2 cache initialization is platform specific
On ARM Cortex A9 platforms the external PL310 L2 cache controller
needs to be initialized dependent on the SoC. For instance on Pandaboard
it needs to call the firmware running in TrustZone's secure world,
on i.MX6 it initializes it directly, on other boards it doesn't need
to be initialized at all, because the bootloader already did so.
Therefore, we should implement the PL310 intialization in board specific
code and not in the base class implementation.

e05d26567d hw: make 'smp' property an aspect (Ref #1312)
This commit separates certain SMP aspects into 'spec/smp' subdirectories.
Thereby it simplifies non-SMP implementations again, where no locking
and several platform specific maintainance operations are not needed.
Moreover, it moves several platform specifics to appropriated places,
removes dead code from x86, and starts to turn global static pointers
into references that are handed over.

a258caa7ab nova: propagate bdf for assign_pci properly
Now, the right PCI bus:device:function (BDF) is reported to the kernel
during assign_pci syscall - beforehand it was ever 0:0.0. The BDF is

was revealed as the DMAR unit for Intel graphics on x201 is not the same
as for all other PCI devices we have drivers for on this platform.

thread destruction was synchronized via a semaphore. There is no need to hold

01643ccd94 cpu_quota hw exynos5: raise error tolerance
From our observations we can tell that the error should not exceed 4%.
However, there is no reasonable explanation by now why the test results
are less stable on these platforms. We have tried several things that
did not lead to an explanation or improvement:

  * changing the timing parameters of the scheduler
  * switching off SMP
  * double-checking the speed of userland and kernel timers

60ba210a6b hw: reference count capabilities in UTCBs
When capabilities are delegated to components, they are added to the UTCB of the
target thread. Before the thread is able to take out the capability id out of
the UTCB and adapt the user-level capability reference counter, it might happen
that another thread of the same component deletes the same capability because
its user-level reference counter reached zero. If the kernel then destroys the
capability, before the same capability id is taken out of all UTCBs, an
inconsitent view in the component is the result.  To keep an consistent view in
the multi-threading scenario, the kernel now counts how often it puts a
capability into a UTCB. The threads on the other hand hint the kernel when they
took capabilities out of the UTCB, so the kernel can decrement the counter
again. Only when the counter is zero, capabilities can get destructed.

d65beb970d dde_linux: KMS-based Intel framebuffer driver (II)
* enable i915 driver from Linux 3.14.5
* tested for generation 5 till 8 GPUs

The driver can be configured at run-time via the config ROM. Every
connector of the graphic card can be configured separately using the
following syntax

  <config>
    <connector name="LVDS-11" width="1280" height="800" enabled="true"/>
  </config>

Also, when enabled within the intel framebuffer driver configuration like
the following

  <config buffered="yes"/>

a simple ram dataspace is propagated to the client and the driver
itselfs copies from that buffer to the framebuffer triggered via refresh
calls. This option is useful to alleviate tearing effects.

The  driver distributes all available connectors of the graphic card and
their supported resolutions via a report. It looks like follows

  <connectors>
    <connector name="LVDS-11" connected="1">
      <mode width="1280" height="800" hz="60"/>
      ...
    </connector>
    ...
  </connectors>

The driver distributes the report only if this is stated within its
configuration, like the following

  <config>
    <report connectors="yes"/>
  </config>

493386ed27 wm: prevent superfluous session upgrades
For each session upgrade performed by a wm client as part of the
Nitpicker::Connection::buffer function, the window manager wrongly
upgraded the wrapped nitpicker session twice: Once by handling the
Root::upgrade, and again by handling of the server-side 'buffer'
operation. Here, the 'buffer' operation was implemented by not merely
forwarding the RPC request to the wrapped nitpicker session but by
calling the 'buffer' method on the wrapped session's connection
object, which implictly issues session upgrades. Consequently,
the window manager would transfer twice the amount of the session
upgrades it received by its clients to nitpicker and eventually ran
out of memory.

The patch fixes the problem by eliminating the call of the
Nitpicker::Connection::buffer method and instead merely forward the RPC
requests to the wrapped nitpicker sessions.

ed774253b6 demo: fix corner case in scout_gfx/icon_painter.h
The original version of the icon painter would reach beyong the
texture boundaries for textures of even width and height, and when
painting an icon with the width or height of the texture.

In this case, p3 would be set to the same value as p2. However, the code
expects p3 to lie within the middle rectangle. However, in this corner
case, the middle rectangle is actually empty. So no pixel can lie within
it. Hence, p3 is positioned by one pixel to the left outside the middle
rectangle, which violates the assumptions when calculating the clipping
and texture offsets. The patch fixes the problem by reducing the size of
the right column by one pixel. This ensures that exists always a
non-zero middle rectangle.

  size         determines the number of bytes written/read in one round
               (default is 4 MiB)
  buffer_size  determines the size of the write-read buffer
               (default is 32 KiB)

In one round the test writes and reads "size/buffer_size" times
from/into a buffer_size'd buffer.

5b6fdc96fc vbox: disable rdtsc VM exit
Trapping rdtsc creates a huge load in some guests, e.g. Windows 8.1,
that use this instruction very frequently. This influences audio
playback/recording in a bad way (distorted sounds, …). As a interim
solution disable the virtualization of rdtsc completely. As long
as each guest VM runs on its own CPU core it should be fine as there
should not be that much interference (TSC warping).

That being said, TSC offsetting as well as adjusting within vbox have to
be evaluated.

ceb04d3c11 nova: avoid race in pager_object destruction
Don't skip the cleanup call if a pager object is marked as blocked.

It happens that the pager_object is in destruction but it is also used
concurrently by the pager thread. The pager thread handling code may set the
pager object to blocked but still uses the pointer to the pager object. Avoid
locking at the state of the pager object and make the cleanup call everytime.

Error output looks like this, where the pf_ip is within

  void Pager_object::_page_fault_handler(addr_t pager_obj)

method and the pf_addr is the stale pointer to the already released pager_object.

no RM attachment (READ pf_addr=xxx pf_ip=xxx from 00 <NULL>)

2b429ee84c base: Dispatch server signal in entry point
Currently, when a signal arrives in the main thread, the signal dispatcher is
retrieved and called from the main thread, the dispatcher uses a proxy object
that in turn sends an RPC to the entry point. This becomes a problem when the
entry point destroys the dispatcher object, before the dispatch function has
been called by the main thread. Therefore, the main thread should simply send an
RPC to the entry point upon signal arrival and the dispatching should be handled
solely by the entry point.

dce6e14e3e os: generalize Session_label, Session_policy
The utilities in os/session_policy.h used to be tailored for the
matching of session arguments against a server-side policy
configuration. However, the policy-matching part is useful in other
situations, too. This patch removes the tight coupling with the
session-argument parsing (via Arg_string) and the hard-wired use of
'Genode::config()'.

To make the utilities more versatile, the 'Session_label' has become a
'Genode::String' (at the time when we originally introduced the
'Session_label', there was no 'Genode::String'). The parsing of the
session arguments happens in the constructor of this special 'String'.
The constructor of 'Session_policy' now takes a 'Genode::String' as
argument. So it can be used with the 'Session_label' but also with other
'String' types. Furthermore, the implicit use of 'Genode::config()' can
be overridden by explicitly specifying the config node as an argument.

platform_execute() is used to initially switch the stack of a
routine/task. While Thread_base::alloc_secondary_stack() properly aligns
the returned stack pointer the x86_64 assembler implementation did not
comply to stack frame management specified in the ABI.

The used (and most simple) stack-alignment check may pass a float to a
varargs function on x86, which requires the compiler to properly save
some XMM registers on stack.

c1492da15b base: do not lock interleaved in object pool
Holding the object pool's lock while trying to obtain an object's lock
can leave to dead-lock situations, when more than one thread tries to
access multiple objects at once (e.g.: when transfer_quota gets called
simultanously by the init and entrypoint thread in core). To circumvent
holding the object pool lock too long, but access object pointers safely
on the other hand, this commit updates the object pool implementation
to use weak pointers during the object retrieval.

b585583ec7 core: do not destroy in object pool's apply scope
Destroying an object within the scope of a lambda/functor executed
in the object pool's apply function leads potentially to memory corruption.
Within the scope the corresponding object is locked and unlocked when
leaving the scope. Therefore, it is illegal to free the object's memory meanwhile.
This commit eliminates several places in core that destroyed wrongly in
the object pool's scope.

24b1f269be Remove Packet_ref from File_system::Packet_descriptor
The intention of Packet_ref was to allow clients to place opaque
references into the packet descriptor itself, which could be observed on
packet completion. Currently no component in our sources uses this
feature and beyond that it is questionable if it should be used at all:
If the server tampers with the ref the client may easily be confused
into observing an incorrect or invalid context. It seems better to
remove the opaque context from the descriptor and leave the actual
implementation to the client and its needs.

ed52d5a211 Introduce 'spec' subdirectories to outline aspects
Instead of holding SPEC-variable dependent files and directories inline
within the repository structure, move them into 'spec' subdirectories
at the corresponding levels, e.g.:

  repos/base/include/spec
  repos/base/mk/spec
  repos/base/lib/mk/spec
  repos/base/src/core/spec
  ...

Moreover, this commit removes the 'platform' directories. That term was
used in an overloaded sense. All SPEC-relative 'platform' directories are
now named 'spec'. Other files, like for instance those related to the
kernel/architecture specific startup library, where moved from 'platform'
directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.

349c15dfe4 timer test: be more tolerant in periodic test
For some platforms (at least hw_zynq on Qemu), the measured time of the
periodic timeout test exceeded the maximum that was previously
calculated without any tolerance. Most likely, this is not a malfunction
of the test subject as the error is pretty small and, of course,
measuring the time produces overhead itself. Introducing a tolerance of
only 0.1% fixes the problem.

26924c9bcd vbox: let the first EMT thread handle timers
By default, the EMT thread of the last vCPU handles expired timers. When
running VirtualBox with 2 vCPUs, it sporadically happens that the EMT
thread of the second CPU clears an 'interrupt pending' flag for the first

expected by our Genode-specific code (failed assertion '!_irq_win' in the
recall handler).

The problem did not occur yet when letting the EMT thread of the first
vCPU handle the expired timers, which is done by this commit as an interim
fix until the problem has been further investigated.

26524edbf4 alarm: reposition reprogrammed alarms in queue
The alarm library failed to handle the case properly where an already
scheduled alarm gets rescheduled before it triggered. Even though the
attempt to reschedule the alarm (twice insertion into alarm queue) was
detected, this condition resulted in the mere modification of the
alarm's parameters while keeping the alarm's queue position unchanged.
This, in turn, may violate the invariant that all enqueued alarm objects
are strictly ordered by their deadlines. The patch handles the case by
dequeuing the alarm object before reinserting it into the queue at the
right position.

8a34d21577 dde_bsd: add recording support to audio driver
The driver is now able to record audio samples. In contrast
to playback it has to be enabled explicitly by setting the
configuration attribute 'recording' to 'yes'. Playback is by
default enabled but may be disabled by setting 'playback' to
'no'. Furthermore it is now possible to configure the mixer
from the configuration. For now, the interface used by vanilla
OpenBSD is just exported.

The following snippet shows how to enable and configure recording
on an Thinkpad X220 where the headset rather than the internal
mic is used as recording source:

! <start name="audio_out_drv">
!   <resource name="RAM" quantum="8M"/>
!   <provides>
!     <service name="Audio_out"/>
!     <service name="Audio_in"/>
!   </provides>
!   <config recording="yes">
!     <mixer field="outputs.master" value="255"/>
!     <mixer field="record.adc-0:1_source" value="sel2"/>
!     <mixer field="record.adc-0:1" value="255"/>
!   </config>
! </start>

In addition to selecting the recording source the playback as
well as the recording volume are set to 255 (maximum).
Information about the available mixers and settings in general
may be obtained by setting the 'verbose' to 'yes' in the config
node.

61f5ca1e4d os: add Audio_in session for recording audio
In line with the Audio_out session a Audio_in session is used to
record audio frames. Like in the Audio_out session shared memory
in form of the Audio_in::Stream is used to transport the frames
from the server to the client. These frames consist of single
channel (mono) samples. An Audio_in::Packet always contains a full
period of frames.

A Audio_in server captures frames and puts them into the
Audio_in::Stream. To do so the server allocates a Audio_in::Packet
from the packet queue embedded in the Audio_in::Stream. If the queue
is already full, the server will override packets and notify the
client by submitting the 'overrun' signal. The client has to cope
with this situation, e.g., by saving packets more frequently.

A client will also receive a 'progress' signal from the server when
a new Audio_in::Packet was submitted to the packet queue.

f87c573695 nova: increase default capability selector count
The reference count get increase to use 2 bytes, so we need the double amount
of selectors as before.

Additionally print a message if we run out of capabilities in a server. Since
our rpc framework is now clever enough to detect that for a printf we don't
need to setup a receive window, we may use a printf instead of a die call.

* Timeouts were increased from 45 and 15 seconds to 60 and 20 seconds

0f05fa6fd4 base: resolve dead lock in weak pointer templates
This commit eliminates the mutual interlaced taking of destruction lock,
list lock and weak pointer locks that could lead to a dead-lock situation
when a lock pointer was tried to construct while a weak object is in
destruction progress.
Now, all weak pointers are invalidated and dequeued at the very
beginning of the weak object's destruction. Moreover, before a weak pointer
gets invalidated during destruction of a weak object, it gets dequeued, and
the list lock is freed again to avoid the former dead-lock.

cc58b11998 hw: replace page table allocator with static one
Instead of organizing page tables within slab blocks and allocating such
blocks dynamically on demand, replace the page table allocator with a
simple, static alternative. The new page table allocator is dimensioned
at compile-time. When a PD runs out of page-tables, we simply flush its
current mappings, and re-use the freed tables. The only exception is
core/kernel that should not produce any page faults. Thereby it has to
be ensured that core has enough page tables to populate it's virtual
memory.

A positive side-effect of this static approach is that the accounting
of memory used for page-tables is now possible again. In the dynamic case
there was no protocol existent that solved the problem of donating memory
to core during a page fault.

/home/no/src/genode/repos/base/include/base/ipc.h:79:4: warning: ‘ret’ may be used uninitialized in this function [-Wmaybe-uninitialized]
    *reinterpret_cast<T *>(&_sndbuf[_write_offset]) = value;
    ^
In file included from /home/no/src/genode/repos/base/src/core/include/trace/session_component.h:19:0,
                 from /home/no/src/genode/repos/base/src/core/trace_session_component.cc:15:
/home/no/src/genode/repos/base/include/base/rpc_server.h:132:42: note: ‘ret’ was declared here
     typename This_rpc_function::Ret_type ret;

The warning occurs for basic return types (like size_t), which are
indeed not initialized. The variable gets its value assigned by the
corresponding 'call_member' overload, to which the variable is passed as
reference. But the compiler apparently is not able to detect this assignment.

Declaring 'ret' with a C++11-style default initializer fixes the warning.

5d678dba9e core: throw Trace::Out_of_metadata in subjects()
While importing trace sources as trace subjects into a TRACE session,
the session quota might become depleted. The TRACE session already keeps
track of the session quota via an allocator guard but the 'subjects' RPC
function missed to handle the out-of-memory condition. This patch
reflects the error condition as an 'Out_of_metadata' exception to the
TRACE client. It also contains an extension of the trace test to
exercise the corner case.

Right now, the feature is available solely on NOVA. On all other base

ef9c745e42 ldso: add memcpy and memset to symbol.map
On ARM, the compiler generates calls to memcpy and memset. Most
dynamically linked programs use the libc, which provides these
functions. However, if a dynamically linked program does not use the
libc (e.g., noux/minimal or the new version of cli_monitor), those
symbols remain unresolved. By adding them to ldso's symbol.map, the
dynamic linker will resolve them with the functions of the cxx
library, which is part of the dynamic linker.

8a99c08ae4 hw: always panic on removal of scheduler head
Because of helping, it is possible that a core thread that wants to
destroy another thread at the kernel is using the scheduling context of
the thread that shall be destroyed at this point in time. When building
without GENODE_RELEASE defined, this always triggers an assertion in the
kernel. But when building with GENODE_RELEASE defined, this might silently
lead to kernel-memory corruption. This commit eliminates the latter case.
Should be reverted as soon as the scheduler is able to remove its head.

3e90542559 nova: use signals with irqs in core
Avoids the need to have per IRQ a thread that blocks synchronously for next
interrupt. Now a thread may wait for multiple IRQs as other signals
simultaneously.

In core no threads are required anymore for IRQs/MSI - the clients (either
the pci_drv or in case of MSI the driver) gets the IRQ delivered directly as
a ordinary Genode signal.

Useful since #1216 and #1487 is now available.
Commit applies feature of #1446 also to IRQ/MSIs.

The assumption that IRQs in the legacy ISA range are always

3a378bb970 libc_noux: remove dependency on 'platform_env.h'
Currently, libc_noux includes the 'base/src/base/env/platform_env.h' file
to be able to reinitialize the environment using the 'Platform_env'
interface. For base-linux, a special version of this file exists and the
inclusion of the generic version in libc_noux causes GCC 4.9 to make wrong
assumptions about the memory layout of the 'Env' object returned by
'Genode::env()'.

This commit moves the reinitialization functions to the 'Env' interface to
avoid the need to include the 'platform_env.h' file in libc_noux.

88034ef836 vbox: enable USB (OHCI) pass-through support
The information about connected devices is obtained from a ROM file named
'usb_devices', which is supposed to contain a device list as in the device
report generated by the USB driver (see issue #1506).

A policy for 'report_rom' would look like:

<policy label="vbox -> usb_devices" report="usb_drv -> devices"/>

If the 'usb_devices' ROM file is not available, a warning message gets
printed and VirtualBox continues without USB pass-through support.

The devices to be passed-through need to have a matching device filter in
the '.vbox' file. Example:

<USB>
    <DeviceFilters>
        <DeviceFilter name="USB Scanner" active="true" vendorId="04a9"
                      productId="2220" remote="0"/>
    </DeviceFilters>
</USB>

The feature was tested with HID devices (mouse, keyboard) and a flatbed
scanner. Mass storage devices didn't work correctly (they also didn't work
with VirtualBox on Linux without the closed-source extension pack).

It should be made sure that the USB driver does not try to control the
devices to be passed-through itself, for example, when passing-through
a HID device, the '<hid/>' config option should not be set.

2d869dd15e usb_drv: generate a device list report
The report lists all connected devices and gets updated when devices are
added or removed.

Example report:

<devices>
    <device vendor_id="0x17ef" product_id="0x4816"/>
    <device vendor_id="0x0a5c" product_id="0x217f"/>
    <device vendor_id="0x8087" product_id="0x0020"/>
    <device vendor_id="0x8087" product_id="0x0020"/>
    <device vendor_id="0x1d6b" product_id="0x0002"/>
    <device vendor_id="0x1d6b" product_id="0x0002"/>
</devices>

There is no distinction yet for multiple devices of the same type.

The report is named "devices" and an example policy for 'report_rom' would
look like:

<policy label="vbox -> usb_devices" report="usb_drv -> devices"/>

The report only gets generated if enabled in the 'usb_drv' configuration:

<config>
    <raw>
        <report devices="yes"/>
    </raw>
</config>

e8f82a1da3 nova: delay UTCB revocation on thread destruction
On NOVA, a Genode thread currently cannot destroy itself by destroying its
own 'Thread' object, because in 'Thread_base::_deinit_platform_thread()'
it cannot call 'Cpu_session::kill_thread()' anymore after it has revoked
its own UTCB.

As solution, the revocation of the UTCB can be delayed until its location
in the context area is needed by a new thread.

27e5d48fd0 dde_oss: remove repository
This repository is superseded by the 'dde_bsd' repository.  Though
OSSv4 served us well, its future is uncertain and having active
upstream development is preferable. In addition the ported Intel
HD Audio driver did not work on any Thinpad model newer than T60.

dcd589d113 l4linux: platform_drv may provide platform session

currently.

@skalk the test will still fail each night as we do not have a nic_drv

c1cb3a6642 Increase initial block for cxx malloc
This patch avoids the attempt to extend the cxx-local heap during the
startup phase of an application. Originally, the static part of the cxx
was merely 100 bytes, which did not suffice to run the minimalistic test
roottask on seL4.

7c133add52 hw: acknowledge IRQs via Kernel::ack_irq
In the past, when the user blocked for an IRQ signal, the last signal was
acknowledged automatically thereby unmasking the IRQ. Now, the signal session
got a dedicated RPC for acknowledging IRQs and the HW back-end of that RPC
acknowledged the IRQ signal too. This led to the situation that IRQs were
unmasked twice. However, drivers expect an interrupt to be unmasked only on
the Irq_session::ack_irq and thus IRQ unmasking was moved from
Kernel::ack_signal to a dedicated kernel call.
