Some functions in the kernel, which create a static object and return its
address, are declared with a GCC 'const' attribute, which can cause GCC
4.9 to optimize the function call out and use the static object's address
without calling the constructor.
Fixes#1509
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
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>
Fixes#1506
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.
Fixes#1505
Enable a platform to specify how the MMIO memory allocator is to be
initialized. On ARM the existing behavior is kept while on x86 the I/O
memory is defined as the entire address space excluding the core only
RAM regions. This aligns the hw_x86_64 I/O memory allocator
initialization with how it is done for other x86 kernels such as NOVA or
Fiasco.
Perform lazy-initialization of FPU state when it is enabled for the
first time. This assures that the FXSAVE area (including the stored
MXCSR) is always properly setup and initialized to the platform default
values.
Perform all FPU-related setup in the Cpu class' init_fpu function instead of
the general system bring-up assembly code.
Set all required control register 0 and 4 flags according to Intel SDM Vol. 3A,
sections 9.2 and 9.6 instead of only enabling FPU error reporting and OSFXSR.
On seL4, we need to convert untyped memory to page frames before being
able to use it as normal memory. There already exists the hook function
'_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.
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
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.
Issue #1498.
These audio drivers enable support for Intel HD Audio (Azalia) and
Ensoniq AudioPCI (ES1370) compatible soundcards. They are ported
from OpenBSD 5.7.
Fixes#1498.
This is especially true for i.MX53 but is not needed on Arndale
currently.
@skalk the test will still fail each night as we do not have a nic_drv
for imx53...
- send a 'state_change' signal on session creation if the device is
already attached
- evaluate the status code of a finished asynchronous operation
- return the number of actually transferred bytes for control transfers,
too
Fixes#1490
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.
Fiasco.OC limits the UTCB area for roottask to 16K. Therefore, the
number of threads is limited to 16K / L4_UTCB_OFFSET. (see
kernel/fiasco/src/kern/kernel_thread-std.cpp:94)
