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.
