By appending a newline to the generated XML data, we prevent the output
from messing with the command prompt when using 'cat' on a shell.
Futhermore, when using line-buffered output, the trailing newline
ensures that the output gets gets properly flushed.
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
- 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
White list access to ports we actually need for our drivers so far and
deny everything else by default. The extend pci config space dataspace is
currently not used and exposes a potential risk (BAR rewrite) - so deny.

Step to move shared irq handling out of core in the long run. So, use
irq_proxy implementation from base in os and implement shared irq handling
in platform driver of x86 (pci_drv).
Fixes#1471
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.
Ref #1464
Use the new asynchronous IRQ interface in the mostly used drivers, e.g.:
* ahci_drv: x86/exynos5
* 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.

This patch adds const qualifiers to the functions Allocator::consumed,
Allocator::overhead, Allocator::avail, and Range_allocator::valid_addr.
Fixes#1481
Currently, the 'pointed session' gets updated only when an input event
occurs, but an update is also needed in other situations, for example
when the view under the current mouse position was moved.
With this commit, the 'pointed session' gets updated whenever the
timer-triggered 'handle_input()' function is called.
Fixes#1473
There are lots of places where a numeric argument of an argument string
gets extraced as signed long value and then assigned to an unsigned long
variable. If the value in the string was negative, it would not be
detected as invalid (and replaced by the default value), but become a
positive bogus value.
With this patch, numeric values which are supposed to be unsigned get
extracted with the 'ulong_value()' function, which returns the default
value for negative numbers.
Fixes#1472
The driver operates in PIO mode only. Depending on the block size (512
bytes versus 128 KiB), it has a troughput of 2 MiB/sec - 10 MiB/sec for
reading and 173 KiB/sec - 8 MiB/sec for writing.
Fixes#1475
This patch enhances the generic SD-card protocol implementation in
sd-card.h with the ability to handle the version 1.0 of the CSD register
(containing the capacity information of older SD cards).
The emergency dataspace is used to accommodate the corner case where
a signal context capability is created while issuing the first
resource request. Normally, the attempt to upgrade the signal-session
quota under such a constrained situation would fail. By freeing the
emergency dataspace in this situation, we regain enough quota to
upgrade the signal session.
This is a follow up commit for "base: Raise RAM quota of signal session
to 16K" and fixes the resource_request test on 64-bit platforms.
A Nic::Session client can install a signal handler that is used to
propagate changes of the link-state by calling 'link_state_sigh()'.
The actual link state is queried via 'link_state()'.
The nic-driver interface now provides a Driver_notification callback,
which is used to forward link-state changes from the driver to the
Nic::Session_component.
The following drivers now provide real link state: dde_ipxe, nic_bridge,
and usb_drv. Currently, OpenVPN, Linux nic_drv, and lan9118 do not
support link state and always report link up.
Fixes#1327
If a client acknowledges the same packet more than once, the packet also
gets freed more than once. At the second attempt the underlaying
Bit_array will throw an 'Invalid_clear' exception, which results in an
uncaught exception that leads to an abort() call in the freeing
component.
Fixes#1462.
The driver for the Freescale eSDHCv2 doesn't support the highest
available bus frequency by now and also the bus width may be set to a
higher value but that needs further checks on the capabilities of the
inserted card.
The commits provide a benchmark as it exists for the OMAP4 SDHC driver.
Fix#1458
The GUID partition table (GPT) is primarily used by systems using
(U)EFI and is a replacement for the legacy MBR. For now, the current
implementation is able to address up to 128 GUID partition entries
(GPE).
To enable the GPT support in 'part_blk' it has to be configured
accrodingly:
! <start name="part_blk">
! [...]
! <config use_gpt="yes">
! [...]
! </start>
If 'part_blk' is not able to find a valid GPT header it falls back
to using the MBR.
Current limitations:
Since no endian conversion takes place it only works on LE platforms
and of all characters in the UTF-16 encoded name field of an entry
only the ones included in the ASCII encoding are printed. It also
ignores all GPE attributes.
Issue #1429.
The hover reports provides information about the session currently
pointed-to, i.e., hovered session. It can be enabled by the 'hover'
attribute of nitpicker's 'report' configuration element
<report hover="yes" />
