The count value can be used to batch timeouts. I.e., if a periodic
timeout triggered multiple times before the timer had a chance to
process them, the count corresponds to the number of passed periods.
On ARM it's relevant to not only distinguish between ordinary cached memory
and write-combined one, but also having non-cached memory too. To insert the
appropriated page table entries e.g.: in the base-hw kernel, we need to preserve
the information about the kind of memory from allocation until the pager
resolves a page fault. Therefore, this commit introduces a new Cache_attribute
type, and replaces the write_combined boolean with the new type where necessary.
Depending on 'src_w' and 'dst_w', different lines of a block to copy may be
32-bit aligned or not, so the alignment of each line needs to get checked.
Fixes#1111.
This commit adds a 'parent_view()' function to the loader session, which
allows to set the parent view of the subsystem's Nitpicker view.
If the function is to be used, this must get done before calling
'start()'.
Fixes#1172.
This patch changes both the Input::Session interface and the skeleton
for the server-side implementation of this interface
('input/component.h').
The Input::Session interface offers a new 'sigh' function, which can be
called be the client to register a signal handler. The signal handler
gets notified on the arrival of new input. This alleviates the need to
poll for input events at the client side.
The server-side skeleton for implementing input services underwent a
redesign to make it more modular and robust. I.e., there are no
global functions needed at the server side and the event-queue
enable/disable mechanism is implemented at a central place (in the root
component) rather than inside each driver.
Fixes#46
This patch changes the top-level directory layout as a preparatory
step for improving the tools for managing 3rd-party source codes.
The rationale is described in the issue referenced below.
