If the guest is not in an interruptible state when the recall handler is
called, an assertion fails. Since the assertion is only relevant if the
recall handler was called during IRQ injection, it should be moved into
the corresponding conditional block which already has the assertion for
the 'IF' flag.
Fixes#1661
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
vCPU after changing the state of a timer device model, which is not
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.
Issue #1660
There are currently some issue with the mixing/filtering code of vbox.
So instead of using the audio subsystem to do filtering and mixing we
bypass it to get better audio qualitiy. That means that the device
model of the VM has to use the same sample rate as the Audio_out/in
sessions, however.
Issue #1647.
With this commit preliminary audio support in VirtualBox is enabled.
The backend supports playback as well as recording sounds from within
a guest VM. Depending on how the guest configures the device model
the audio output may sound disorted. If the guest uses buffers that
are too small, i.e., 10 ms or less, frequent buffer underruns will
occure.
To get this low-latency one has also to increase vbox' update hz
to 200 (i.e., 5ms).
Fixes#1647.
Run script depending on VFS plugins (i.e., shared objects) like
vfs_jitterentropy.lib.so have to state this dependency rather the actual
binaries linked against libc. The latter introduces a library dependency
that is just not there. For example, the dependency on vfs_jitterentropy
is a result from the config node for libc which automatically loads the
plugin.
With the introducation of the Audio_in session interface it makes
sense to rename the current available audio drivers. At the moment
only the dde_bsd audio_drv supports Audio_out as well as Audio_in.
The Linux audio_drv only supports Audio_out (there is no demand for
Audio_in support currently) but is renamed nonetheless to make it
easiert to write generic run scripts.
Issue #1644.
This exit handler is called by the NOVA kernel now when the VM uses PAE
with nested paging and the PDPTE registers need to get updated. With this
commit, an error message is printed if this situation occurs.
Fixes#1640
Removed the Nic::Driver implementation. All nic servers now inherit from
Nic::Session_component. Packet stream signals are dispatched to
the 'handle_packet_stream' function within a session component. Thus, nic
servers now have direct access to the packet stream channels, making handling
more flexible.
Adjusted nic_loobpack, dde_ipxe, wifi, usb, lan9118, Linux nic, and OpenVPN to
the new interface.
Fixes#1602
Use printf format specifier with correct size to log error code which is
if type uint32_t. Also print the error code in hex since this simplifies
lookup as the error values are also defined as hexadecimal values, see
[1].
Fixes#1600

The result of the second run (TCP_MAERTS) gets extracted wrongly - due to the
change introduced by commit "run: always append to output buffer"
(Issue #1327). The output buffer is no longer reseted between several
run_genode_until invocation within a run script.
This patch moves the VFS file-system factory to a separate vfs library
that is independent from libc. This enables libc-less Genode programs to
easily use the VFS infrastructure.
Fixes#1561
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.
Fixes#1510
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.
Fixes#1507
On our test machine the xhci controller has a usb3.0 network adapter attached
and the xhci controller is the only usb controller which has MSI support,
so let us use and test it.
Issue #1216
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.
