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.

58178949ef hw_x86_64: Make AHCI driver work
The assumption that IRQs in the legacy ISA range are always
edge-triggered is wrong. For the free-for-use IRQs it depends on the
actual device which uses the specific IRQ. Therefore, treat IRQs 9, 10
and 11 as level-triggered.

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.

1207a4cecd fiasco: remove 'const' GCC attribute from some functions

without calling the constructor.

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.

initialization with how it is done for other x86 kernels such as NOVA or

'_export_ds' that is principally suitable for such tasks. It is
currently solely used on Linux where we have to create a file for each
dataspace. To make the hook useful also for seL4, we need to call
_export_ds prior _clear_ds. Otherwise, we would try to clear memory that
is still untyped.

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.

c9272937e7 CPU session: apply quota via relative weightings
Physical CPU quota was previously given to a thread on construction only
by directly specifying a percentage of the quota of the according CPU
session. Now, a new thread is given a weighting that can be any value.
The physical counter-value of such a weighting depends on the weightings
of the other threads at the CPU session. Thus, the physical quota of all
threads of a CPU session must be updated when a weighting is added or
removed. This is each time the session creates or destroys a thread.

This commit also adapts the "cpu_quota" test in base-hw accordingly.

* gpio_drv: imx53/omap4
* input_drv: imx53/dummy
* ps2_drv: x86/pl050
* timer_drv

Now, the Irq_session is requested from Gpio::Session:

From now on we use an asynchronous IRQ interface. To prevent triggering
another GPIO IRQ while currently handling the former one, IRQs must
now by acknowledged explicitly. While here, we also changed the GPIO
session interface regarding IRQ management. The generic GPIO component
now wraps the Irq_session managed by the backend instead of using the
GPIO backend methods directly. A client using the GPIO session may
request the Irq_session_capability by calling
'Gpio::Session::irq_session()' and can use this capability when using
a local Irq_session_client.

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.

There were two bugs. First, the caller of Kernel::await_signal wasn't
re-activated for scheduling. Second, the caller did not memorize that he
doesn't wait on a receiver anymore which had bad side effects on further
signal handling.

60e392f0c0 hw: support Wandboard Quad (i.MX6)
The port uses the Cortex-A9 private timer for the kernel and an EPIT as
user timer. It was successfully tested on the Wandboard Quad and the CuBox-i
with the signal test. It lacks L2-cache and Trustzone support by now.

Thanks to Praveen Srinivas (IIT Madras, India) and  Nikolay Golikov (Ksys Labs
LLC, Russia). This work is partially based on their contributions.

c82f5e9269 hw_x86_64: Do not mask edge-triggered interrupts
Do not mask edge-triggered interrupts to avoid losing them while masked,
see Intel 82093AA I/O Advanced Programmable Interrupt Controller
(IOAPIC) specification, section 3.4.2, "Interrupt Mask":

"When this bit is 1, the interrupt signal is masked. Edge-sensitive
interrupts signaled on a masked interrupt pin are ignored (i.e., not
delivered or held pending)"

Or to quote Linus Torvalds on the subject:

"Now, edge-triggered interrupts are a _lot_ harder to mask, because the
Intel APIC is an unbelievable piece of sh*t, and has the edge-detect
logic _before_ the mask logic, so if a edge happens _while_ the device
is masked, you'll never ever see the edge ever again (unmasking will not
cause a new edge, so you simply lost the interrupt)."

So when you "mask" an edge-triggered IRQ, you can't really mask it at
all, because if you did that, you'd lose it forever if the IRQ comes in
while you masked it. Instead, we're supposed to leave it active, and set
a flag, and IF the IRQ comes in, we just remember it, and mask it at
that point instead, and then on unmasking, we have to replay it by
sending a self-IPI." [1]

e5f26fa8db base: Raise RAM quota of signal session to 16K
On base-hw/x86_64 the quota of the signal session is not sufficient due to
the large size of the Signal_session_component. Increasing the quota to
16K avoids signal-context resource exhaustion messages as emmitted by the
run/launcher scenario:

7ce8464b3a hw_x86_64: Enable FPU support
* Enable the use of the FXSAVE and FXRSTOR instructions, see Intel SDM
  Vol. 3C, section 2.5.
* The state of the x87 floating point unit (FPU) is loaded and saved on
  demand.
* Make the cr0 control register accessible in the Cpu class. This is in
  preparation of the upcoming FPU management.
* Access to the FPU is disabled by setting the Task Switch flag in the cr0
  register.
* Access to the FPU is enabled by clearing the Task Switch flag in the cr0
  register.
* Implement FPU initialization
* Add is_fpu_enabled helper function
* Add pointer to CPU lazy state to CPU class
* Init FPU when finishing kernel initialization
* Add function to retry FPU instruction:
    Similar to the ARM mechanism to retry undefined instructions, implement a
    function for retrying an FPU instruction. If a floating-point instruction
    causes an #NM exception due to the FPU being disabled, it can be retried
    after the correct FPU state is restored, saving the current state and
    enabling the FPU in the process.
* Disable FPU when switching to different user context:
    This enables lazy save/restore of the FPU since trying to execute a
    floating point instruction when the FPU is disabled will cause a #NM
    exception.
* Declare constant for #NM exception
* Retry FPU instruction on #NM exception
* Assure alignment of FXSAVE area:
    The FXSAVE area is 512-byte memory region that must be 16-byte aligned. As
    it turns out the alignment attribute is not honored in all cases so add a
    workaround to assure the alignment constraint is met by manually rounding
    the start of the FXSAVE area to the next 16-byte boundary if necessary.
