This patch installs the parent endpoint selector and the PD's CNode into
a PD at its creation time. Furthermore, it initializes the IPC buffer
for the main thread of the new component.
This allows us to see debug messages printed at the eary initialization
of init (before init is able to obtain the regular LOG session). This
will be reverted as soon as the initialziation of the non-core base
environment works.
To build core and other Genode components, we will need to extend the
base-common.mk library with additions that conflict with the
minimalistic root-task environment of test/sel4. To preserve the
minimalistic root task, we need to decouple it from the base-common
library.
We implicitly know that the value range will not exceed access_t despite
the integer-based arithmetics, i.e., negation and shift operations.
Fixes#1524
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
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.
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
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
