Core uses an instance of 'Pd_session_component' as a representative
for RAM/cap quota accounts used whenever session resources are
donated to core's services. All other facets of 'Pd_sesson_component'
remain unused. Core's instance of 'Pd_session_component' is hosted
at 'Core_env'. Upon its construction, all unused facets of
'Pd_session_component' are initialized by dummy arguments in 'Core_env'.
To overcome the need for dummy arguments, this patch splits the
accounting part of the PD-session interface into a separate
'Pd_account' interface. This gives us the prospect of narrowing
core's current use of 'Pd_session_component' by 'Pd_account',
alleviating dead code and the need for any dummy arguments.
Issue #5408
Replace the use of the global 'core_env()' accessor by the explicit
delegation of interfaces.
- For allocating UTCBs in base-hw, 'Platform_thread' requires
a way to allocate dataspaces ('Ram_allocator') accounted to the
corresponding CPU session, a way to locally map the allocated
dataspaces (core's 'Region_map'), and a way to determine the
physical address (via 'Rpc_entrypoint') used for the initial
UTCB mapping of main threads. Hence those interfaces must be
passed to 'Platform_thread'.
- NOVA's pager code needs to look up 'Cpu_thread_component'
objects using a map item as key. The lookup requires the
'Rpc_entrypoint' that hold the 'Cpu_thread_component' objects.
To make this 'Rpc_entrypoint' available, this patch adds
the 'init_page_fault_handing' function.
- The 'Region_map_mmap' for Linux requires a way to look up
'Linux_dataspace' objects for given dataspace capabilities.
This lookup requires the 'Rpc_entrypoint' holding the dataspaces,
which is now passed to 'platform.cc' via the new Linux-specific
'Core_region_map::init' function.
Issue #5408
Instead of repeatedly printing error messages when a device is not
available anymore, print an error once and then sleep forever.
There is no dynamic behaviour with respect to device availability
implemented in the libusb yet. Instead, you can manage libusb
components externally.
Ref genodelabs/genode#5401
When constructing an Usb::Interface and implicitly corresponding
Usb::Endpoint instances only select endpoints relevant for the
given alternate setting.
The libusb has to be changed to delegate the correct alternate
setting to the constructor too.
Fixgenodelabs/genode#5394
Instead of directly process URBs whenever a USBPacket arrives from
the Qemu ported XHCI layer, send a local signal to the I/O handler,
which will process the requests after leaving certain sensible
code pathes like usb_packet_complete. Otherwise, it might happen
that a packet, which was still marked as being queued gets already
completed, which leads to an assertion and hang of the library.
Fixgenodelabs/genode#5389
- add a check to detect if a different thread has
initialized the internal object in the meantime
- remove ENOMEM error since the 'Libc::Allocator'
is not supposed to throw exceptions
- remove init mutex from 'pthread_condattr_init()'
since there is no implicit initialization which
could happen in parallel like with mutex/cond/rwlock
Issue #5386
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.

The recent changes of the GUI stack (proper accounting of cap and RAM
resources by the window manager and nitpicker, output buffered at the
server side) require quota adjustments at various GUI-related places.
Issue #5356
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.
