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
By calling run_genode_until twice, we take into account that the boot
time on some boards might long than on others, while still verifying
that the second "set_rtc" is reported within about 1min (+10s).
Fixes#5306
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
- Move header to base/include to make it applicable for base types
like 'Affinity' down the road.
- Represent 'Rect' as typle of point and area, which is the most
common form of initialization, creates in valid 'Rect' by default.
- Turn Point, Area, and Rect into compound types, making x, y, w, h, at,
area accessible without a method call
- 'Rect::Compound' function for constructing a 'Rect' from two points,
replacing a former constructor
- Use result type 'Rect::Cut_remainder' instead of out parameters.
Fixes#5239
In '_generic_syncobj_wait' check if sync-objetcs exist, return error
otherwise. Do not wait because the execution model is synchroneous,
meaning no batch buffers are in execution when this function is called
(_drm_mutex).
issue #5224
Use pthread_mutex because the EP can block while the thread executing a
batch buffer and waiting for a completion signal in the VFS-GPU plugin
can still make progress.
Also return to coarser locking until we support Sync-Object Wait
semantics.
issue #5224
Freshly allocated BOs from libdrm have to be zeroed. Since the libdrm/iris
caches VRAM allocations, we don't want to attach/detach parts of dataspaces at
every allocation. Some objects are used long (through caching in the iris
Gallium driver). Therefore, zero object on release where the region might
already be mapped.
