Since the preset contains mesa_gpu-intel, it is specific to the pc
platform. Other platform-specific repos (such as allwinner) may contain
their own preset with the same name. To prevent that Sculpt images use
the wrong preset due to the particular order in the build.conf, we move
the preset into the pc repo.
Fixes#5322
Avoid double allocation of alternative stack. Genode's sigaltstack variant
allocates the stack with alloc_secondary_stack. Disable the warning of
sigaltstack by using explicitly the nullptr in ss_sp.
Issue #5305
This interface change gives GUI servers the freedom to allocate view
capabilities at the time of request instead of the creation time of the
view. This is useful because view capabilities are rarely needed.
Issue #5242
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
This patch reworks the view-ID handling within the nitpicker GUI server
and the window manager. The namespace of view handles are now represented
as an Id_space. In constrast to the former "handles", which could be
invalid, IDs cannot be semantically overloaded with anything other than
an actual view reference. There is no notion of an invalid handle.
IDs are like C++ references (which cannot be a nullptr).
This change requires the code to be more explicit. E.g., the stacking of
a few at the front-most position can no longer be expressed by passing
an invalid handle as neighbor.
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 #5242
Issue #5245
This patch replaces the optional parent argument of the create_view
RPC function by a dedicated create_child_view RPC function. This
is a preparatory step of removing the notion of an invalid handle
as a special case.
Issue #5242
The fd event handling uses the fd to directly access the array slot and
expects the fds to be contiguous and capped.
Since the returned fds from our libc were much larger than expected,
because the libc itself consumes multiple fds when managing sockets,
using the fd in this manner leads to memory corruption.
This commit limits the maxfds to 63 and always allocates 1024 slots
in the fd-array.
Fixes#5320.
Add extended FPU state detection and handling (via xsave and friends) to the
kernel, which has to store/load more FPU state (~512 -> 2k++) during context
switching of threads. Additional the referenced nova branch contains various
optimization during VM destruction and cross core IPC resource caching.
This FPU work is based upon upstream NOVA kernel and Hedron commits.
Issue #5314Fixes#3914
some more adjustments are needed for xsave support, but this port is scheduled
to be removed. Just disable xsave for the time being to make nightly test
happy.
Issue #5314
The commit that added firmware loading via the VFS (see #4861)
introduces a double-free bug where the memory that contains the
image is freed twice, once from the callback and once from the
work function.
As alle examined drivers call 'release_firmware' from the callback
function themselves, remove the erroneous 'kfree' call from the
work function.
Issue #5264.
The 'update_quality_interval' instructs the wifi driver to update
the approximated link quality to the currently connected AP every
30 seconds.
Issue #5262.
This commit introduces support for querying and updating the signal
quality of the established connection to the current accesspoint.
By setting the 'update_quality_interval' to a non-zero value specified
in seconds the 'state' report will be updated to incorporate the
current signal quality. It uses the same approximation as is already
in use by the scan results.
Fixes#5262.
Now, USB audio class devices become available in Sculpt, e.g., for vbox
passthrough, and are not automatically grabbed by the usb_hid class=3
policy. In the future, interface/endpoint level policies will enable
driving the HID interface only from usb_hid while a usb_audio driver
controls the rest of the device.
This commit adds the firmware image for the AX200 device as found
in the Tuxedo Pulse 15 Gen1, the 9560 as found in the Starlite and
the for devices found in the T430/T530.
Fixes#5282.
Turn some of the current assertions into warnings/error messages and
continue boot. Print the messages as soon as core_log is initialized,
so that on live/release systems (Sculpt OS) it may be inspected later on.

The code to group together SMT threads of one CPU and to move P-Core to
the beginning of Genode's affinity-space, did not consider to run on
SOCs with only E-Core CPUs.
Re-structure the code to support e-Core only SOCs.
Additionally, provide a fallback mapping in case of CPU id reordering problems.
Track faulty re-mapping and delay the reporting until core_log is initialized,
so that the warnings is visible to consumers, e.g. on Sculpt OS.
