This patch adds a 'Color::print' method as counterpart to the 'ascii_to'
function. If the color is opaque (alpha is 255), its output has the form
"#rrggbb". If the color has a distinct alpha value, the output has the
form "#rrggbbaa". The new version of the 'ascii_to' overload for 'Color'
is able to deal with both forms.
This is a follup-up commit for "driver_manager: add fb_boot_drv
support". It refines the heuristics for selecting the most suitable
framebuffer driver be prevent boot_fb_drv from being preferred over
the VESA driver when running in Qemu.
The synchronization with the ACPI driver is not needed when starting
acpica at a later stage. It could already be disabled via the
'acpi_ready="yes"' config attribute. However, acpica still
unconditionally requests the so-called "Acpi" service, which is an
alias for the platform_drv's "Platform" service. This patch disables the
use of this alias when the 'acpi_ready' synchronization is disabled.
This patch supplements init's service-forwarding mechanism to propagate
the insufficient RAM/cap quota conditions from the server to the client.
Without it, the client's session request stays pending infinitely.
The debug version comes with an unwelcome libc dependency, which is
solely needed for the formatted output of error messages. Since the
distinction between the regular and the debug versions remained unused
in practice, this patch removes the debug version.
This is a follow-up patch to "init: periodic state updates if sensible".
In situations where the report rate is deliberately limited via the
'delay_ms' attribute while also reporting child-resource stats, we don't
want generate reports at a fixed rate of one second. This patch limits
the rate according to the 'delay_ms' value.
The input filter used to temporarily close all input sessions upon its
reconfiguration. In most cases, the same set of sessions is
re-established immediately afterwards. However, at the server (driver)
side, the closing of the session implicitly disables the input-event
queue. Hence events generated by the hardware while the session is
closed are dropped. This becomes a noticeable problem when using the
recently added <rom> modifier feature for handling capslock. The change
of the ROM always triggers the re-configuration of the input filter.
When pressing capslock and other keys at a high rate, press/release
events may get lost.
This patch solves this problem by maintaining all input sessions that
are defined in both the old and new configuration. It thereby removes
the short duration where the input event queues are temporarily disabled
at the drivers.
This makes '/' and the actual root of VFS distinguishable. A VFS root
may contain one ore more '/' entries for each file system. 'opendir' for
the VFS root opens all file systems via 'open_composite_dir', while
'opendir' for '/' only returns a VFS handle.
Fixes#2569
This patch adds a sanity check to the Event::type accessor. If the key
code of a given PRESS or RELEASE event is out of the valid range, it
reports an INVALID event. This way, client side code does not need to
deal with such edge cases. E.g., on Lenovo notebooks, the ps2 driver
reports strange key events when pressing shift-pageup/pagedown,
violating the general assumption that there is a release event for each
press event. By flagging these events as INVALID, the client-side logic
stays intact.
By now the file system gets mounted and unmounted on demand (whenever
the first clients comes along and whenever the last client leaves).
As a precaution we now also try to mount and unmounted the file system
in the init phase to prevent the first client from failing to its own
surprise.
Issue #2558.
Currently, LxIP peers need a lot of RAM (the simple test-client/server for the
nic_router test need at least 28 MB per component). As the nic_router test
previously used 6 instances of such components and a lot of other components,
it had issues with insufficient RAM on some platforms. By using two new
LwIP-based UDP tests instead, we save more than 100 MB.

Check at the VFS server that the capability cost of sessions do not
exceed the session quota donation. Raise the default initial capability
donation for File_system connections.
Fix#2553
Instead of storing whether the first item in the timeout list was already
programmed using the timer service, just program the first timeout in the
list unconditionally. In the past we lost a timeout at least when using the
usb ethernet driver on hw/arndale sporadically.
Previously the destructors of classes derived from Source were not
called when destructing a Source because Source missed the declaration
of a virtual destructor. This caused at least problems when
reconstructing a Chargen_source with its Chargen_repeater that includes
a One_shot_timeout. In this case, the members of the Alarm behind the
timeout were not reset and the next time beeing used the Alarm appeared
to be still active which wasn't true.
Fixes#2570
Instead of changing the attributes (e.g., Xd bit) of the top-level page-tables,
set them to allow everything. Only leafs of the paging hierarchy are set
according to the paging attributes given by core. Otherwise, top-level page-
table attributes are changed during lifetime, which requires a TLB flush
operation (not intended in the semantic of the kernel/core).
This led to problems when using the non-executable features introduced by
issue #1723 in the recent past.
The dependency was added as a supposed work-around of a dysfunctional
fork when building bash as depot archive. However, it turned out that
the actual problem was related to the timestamps of 3rd-party source
file, which were discarded by the recipes/src/bash/content.mk.
A new configuration may implicitly change the domain color of the
currently focused session. We need to refresh the report to trigger an
update of the status bar.
This commit replaces the old xray_trigger component by a new component
called global_keys_handler. For details, please refer to the issue text
and the accompanied README file.
Fixes#2554
Without this patch, usb_drv would issue a resource request when
assigning a USB device to a VM in the sculpt scenario.
Furthermore, the patch adjusts the intel_fb quota to enable it on
devices where the driver allocates the framebuffer in many 4K pieces.
