Because the implemantations for Lima and Vivante are linked into a
single library we cannot have two Gpu::Vram classes in the same
namespace. In case this happens any methods using the same signature are
weak symbols and the first one found by ld will be used = undefined
behavior.
issue #5356
issue #5369
In multi-monitor scenarios, the mode is no longer a single rectangular
area but a panorama with potentially many captured rectangles. This
patch replaces the former 'mode' and 'mode_sigh' RPC by a new 'info'
ROM accessor.
Issue #5353
Propagate the want of an alpha channel as attribute of Framebuffer::Mode
instead of passing this property as a separate bool argument.
This clears the way for adding useful accessors for pixel/alpha/input
surfaces to the Mode type as a subsequent step.
Issue #5351
This patch adds the physical screen size as argument to the
Capture::Session::buffer RPC function, which allows drivers to
propagate DPI information to the GUI server. While changing the
the interface, the patch replaces the former use of C++ exceptions
by a result type. The 'Buffer_result' is handled transparently by the
Capture::Connection. The client.h code is now integrated in
connection.h.

This patch enables basic use cases of the POSIX 'alarm' function, which
schedules the delivery of a SIGALRM signal after a specified amount of
seconds.

This commit adds support for TIOCSETA and TIOCFLUSH in a dummy fashion
that is enough to allow vbox6's serial-port implementation to print
lines to the log.
Issue #5330.
This commit allows for suppressing failed extract operations by
setting the 'ignore_failures' attribute in the 'config' node.
It is intended for operating the component in batch-mode where
multiple archives need to be extracted but failing to extract
some of them can by ignored. The default value of this option
is 'false'.
It also adds the 'stop_on_failure' attribute that instructs
the component to stop processing any following archives after
it already has failed to do so. The default value of this
option is 'true' to preserve the current behavior.
Issue #5326.
This patch moves the management of view IDs from the server to the
client side. The former 'create_view' and 'create_child_view'
operations do no longer return a view ID but take a view ID as
argument. While changing those operations, this patch takes the
opportunity to allow for initial view attributes. Combined, those
changes simplify the window manager while accommodating typical
client use cases with less code.
To ease the client-side ID management, the Gui::Connection hosts
a 'view_ids' ID space for optional use. E.g., the new 'Top_level_view'
class uses this ID space for ID allocation. This class accommodates the
most typical use case of opening a single window.
The 'alloc_view_id' RPC function is no longer needed.
Issue #5242
Express the allocation of a new view handle by a dedicated RPC function
instead of passing an invalid view handle to the existing 'view_handle'
function.
This eliminates the notion of invalid view handles at the GUI session
interface, clearing the way for managing view handles via an Id_space.
Issue #5242
This patch eliminates the use of invalid view handles as special
Session::Command arguments. The TO_FRONT and TO_BACK operations
interpreted as invalid neighbor as top-most or back-most position.
Those corner cases are now expressed via dedicated commands. The
new stacking commands are FRONT, BACK, FRONT_OF, and BEHIND_OF.
While changing the command interface, the patch removes the OP_
prefix from the opcode values.
Issue #5242
- Rename framebuffer_session to framebuffer and
input_session to input as those RPC interfaces are no longer
meant to be used as stand-alone sessions.
- Host Connection::input and Connection::framebuffer as public
members, thereby removing the use of pointers. This simplifies
the client-sized code. E.g., '_gui.input()->pending()' becomes
'_gui.input.pending()'.
Issue #5242
To maintain ease of use at the client side, the OUT_OF_RAM and
OUT_OF_CAPS results are handled at the 'Gui::Connection' now.
Gui::Connection does not inherit the Gui::Session interface any longer,
which allows for the use of different result types.

Issue #5245
Allocate a Genode known stack via alloc_secondary_stack and register it
as alternative stack via Signal:use_alternative_stack().
The original semantic of Posix, where the caller may choose arbitary stack
pointers is currently not possible. Warn about the fact.
Issue #5305
Fix the wrong assumption about isochronous packets being always send
with maximum EP's packet size. Instead the isochronous cache now contains
a sizes array to deal with arbitrary packet sizes.

- Remove exceptions
- Use 'Attr' struct for attach arguments
- Let 'attach' return 'Range' instead of 'Local_addr'
- Renamed 'Region_map::State' to 'Region_map::Fault'
Issue #5245Fixes#5070
poll(2) needs to handle invalid file descriptors in the pollfd struct,
specifically -1 as it may be used to disable entries in the fds[] array.
Fix a possible nullptr dereference by checking the File_descriptor
pointer returned by find_by_libc_fd() for validity and skip processing
of any unresolved FDs, effectively implementing standard POSIX
semantics.
Fixes#5249
With libxml2 >= 2.13, the `-path` argument can no longer be used for
setting search paths for xsd files. Instead, we use an XML catalog to
replace genode:// URIs with absolute paths.
Fixes#5248
Add special handling for root bridge access for
12th Gen Framework laptop and Thinkpad X1 Nano Gen2
to avoid bogus MMIO memory accesses as seen in #5234 and #4643.
Fixes#5234
This exception got introduced as a mere convenience for implementers of
'Child_policy' but required a special case in the base library.
Following the goal of eliminating exceptions from the base system,
this patch removes it by making a server_id_space mandatory.
Issue #5245
- Replace 'typedef' by 'using'
- Avoid plain pointers
- Import Genode namespace into Gui::
- Use enum class
- Use Attr struct for passing multiple attributes
- Turn testnit into proper Genode::Component
- Use distinct types for top-level and child views
- Remove dependency from timer
- Use util/geometry.h
