In ROM mode the global CapsLock state is controlled by the capslock ROM
by virtual KEY_CAPSLOCK events.
Guests are easily confused by spurious KEY_CAPSLOCK input events in
caps="rom" mode. These spurious events may reach the VMM if KEY_CAPSLOCK
is not pressed as first key in a combination and, therefore, is not
filtered as global key. We filter KEY_CAPSLOCK in ROM mode in the VMM
explicitly, but let it pass in non-ROM mode.
Per default RAW mode is used and CapsLock key events are sent unfiltered
to the guest.
Enable watching files via the inotify interface of the Linux Kernel.
Delivery of watches to components is staggered in order to prevent an
overflow of the ACK queue in cases when a lot of changes are made to the
file system from the Linux side.

Because qemu-usb allocated host devices after 'USB_HOST_DEVICE' in the
object array and 'USB_WEBCAM' is loacated after 'USB_HOST_DEVICE' the
webcam model can overwrite an already allocated pass-through device. As
a solution add the 'USB_FIRST_FREE' to make it clear from where host
devices can be allocated. Also increase the number of supported host
devices to eight.

If no window has ever been focused, next() always returns an invalid
window id. As a consequence, there is no way to cycle through the focus
history without an explicit focus event (e.g. mouse hover).
Instead, next() should return the first window from the focus history if the
currently focused window is not present.

The wpa_supplicant refuses to set the BSSID in case it is quoted.
Removing the quotes allows for specifying the BSSID in the
configuration.
Fixes#4175.
A reset domain can consist of one or several reset-pins
denoted by name that are assigned to a device.
When the device gets acquired via the Platform RPC API,
the pins are de-asserted, and asserted again when the
device gets released.
A configuration looks like the following:
<device name="mipi_dsi>
<reset-domain name="mipi_dsi_pclk"/>
...
</device>

Introduces the notion of a transaction that consists of one or more
messages. Whereby a message has a read or write direction and consists
of one or more bytes.

Report via platform_info the capabilities of the kernel, e.g. ACPI and MSI.
With the commit the try-catch pattern on IRQ session creation by the platform
driver is avoided.
Issue #4016
- Do not perform desctruction on report updatea in EP because
'unregister_device' may block on Led state 'update' (synchronous
control message) leading to the driver being stuck because no more
signals are received
- Check if device is present in 'submit_urb' calls
fixes#4166
- Signal device ready depending on state (ready or not) immediately or
when "actconfig" is set
- Report new devices when ready
- Drain packet stream in case there is no device present (needed for
synchronous operations at client side)
- Do not use 'session_device' on device destruction, check pointer
directly instead

Adds the <new-file> operation to the fs_tool. When configured, the
<new-file path="...">...</new-file> tag will cause creation or overwriting of
the file given through the 'path' attribute. The file will contain the text
content of the tag.
Ref #4032
This patch moves the utility from the app/text_area to os/vfs.h to make
it easier to use by other components. By hosting the 'New_file' as a
friend alongside the 'Directory', we can now pass a 'Directory' as
constructor argument, which is consistent with other utilities such as
'File_content'.
As a further improvement, the new version supports the implicit creation
of the directory hierarchy leading to the new file.

Mapping normal memory bufferable restores support for unaligned reads on

By adding an attribute 'size="yes"' to a query, one instructs fs_query to
report also the size of each queried file as attribute 'size' of the
corresponding 'file' node.
Ref #4032
The fs_query component used to try watching all files it found resulting in
errors on files that are not watchable. For some files, however, the watch-
feature doesn't make sense as they are not readable (no content, no size).
Now, fs_query will check first whether a file is readable and skip watching
if it isn't.

fs_query will check first whether a file is readable and skip printing the
content of those that are not.

Managing ssh event file descriptors was performed from two different

Issue #4094
For fs_file_systems, reads are limited to the size of the packets from the
File_system session. Hence, we cannot read the large files in one go.
This fix is particularly helpful for fonts_fs, as it enables including font
files from a File_system.

Comment in Linux sources:
Since an ethernet header is 14 bytes network drivers often end up with
the IP header at an unaligned offset. The IP header can be aligned by
shifting the start of the packet by 2 bytes. Drivers should do this
with:
skb_reserve(skb, NET_IP_ALIGN);
This is ensured when using netdev_alloc_skb_ip_align().

This patch takes advantage of block transfer interrupts on Intel XHCI
controllers which is used during isochronous transfers. Because of a bug
in hardware (see usb_host_isoc_bei.patch header), this feature has been
disabled for Intel leading to up to 8000 interrupts/s for isochronous
transfer causing severe CPU consumption on Genode. With this commit we
lower host driver consumption to normal levels.

A Lx::Task is now associated to a USB device not the session any more.
This implies that a task lives as long as the device making it possible
to gracefully handle outstanding requests (i.e., synchronous) in case
the session has been closed.

The old port version contained '*.ali' files that were build with an older GCC
which led to problems when compiling packages that use the port with the new

When loading shared libraries via the 'Shared_object' interface display
all additionaly loaded libraries in case 'ld_verbose' is configured. Up
until now, only the loaded library was displayed. In order to determine

'Shared_object' the reference counter is used.

The default size is on most kernels 512M. On OKL4 we have to use 800M,
because of the statically configured memory ranges in the OKL4 kernel.
By avoiding a specific amount of memory, the default Qemu memory sizes are
used.

Download gmp, mpc and mpfr with the download script provided by the

the Genode tree.
