The commit avoids the race between checking for the NEM state and the decision
to notify (poke) the NEM backend (nem.cc).
- ever notify about POKE flag for remote vCPU
- check synchronized for NEM state
- store recheck flag and apply on next switch_to_hw
Issue #4313
In the default setting the number of root ports is set to 4. This
also limits the number of USB host devices that may be attached to
the VM. Since the USB webcam shares the slots, that leaves us with
only 3 available USB2 slots to attach USB host devices. Depending on
the use-case that might not be enough.
This commit statically increases the number of ports to 8 each and
adapts the qemu-usb glue-code accordingly.
Many thanks to Raphael for initial investigation and workaround.
Fixes#4310.
Accidentally, the size of IOMEM dataspace got accounted within the
implementation of the platform driver for ARM. Instead we should
only account a bit for the metadata and paging of the I/O memory.
Fix#4307
The custom ack avail handler is required for zero-copy nic drivers (e.g.
the zynq nic driver), which must release the corresponding DMA buffers.

This patch adds a missing call of '_handle_decorator_margins' at
construction time. Up to commit "report_rom: versioning and explicit
notification" this problem was masked by an unconditional signal, which
implicitely triggered the call.

Now that we have appropriate native driver for them add keyboard and
mouse devices to virt_qemu machine. Make sure qemu exposes those new
devices in modern, VirtIO 1.0 mode. At leasts qemu 5.1.0 still uses
pre 1.0 mode in default setup.
Issue #4282
This component can service Qemu VirtIO mouse, keyboard and tablet
devices. The implementation is based on VirtIO 1.1 device spec. Its
described in section 5.8 "Input Device".
Issue #4282
Those symbols are not satisfied by any code or dependency of libm. As
result calling cprojf function will always crash on Genode. This crash
can be turned into link time error by adding --no-undefined to LD_OPT.
This patch provides the missing symbols by including isninf.c in libm
build.
Fixes#4299
When rebasing my local branch on top of sculpt-21.10 tag I've noticed
two problems.
The code in new_delete.cc does not include new header file. This works
fine with GCC, but fails with clang because std::align_val_t type is
not defined anywhere according to clang. It looks like GCC pulls this
header indirectly somehow.
The second problem can be seen if one disallows undefined symbols in
executables and shared_libraries. This can be seen with both GCC and
clang by adding --no-undefined to LD_OPT. With such change in place core
fails to link due to:
ld.lld: error: undefined symbol: operator delete(void*, std::align_val_t)
>>> referenced by thread.h:448 (/home/tworaz/devel/genode/repos/base-hw/src/core/kernel/thread.h:448)
>>> thread.o:(Kernel::Core_main_thread::~Core_main_thread()) in archive debug/core-hw-virt_qemu.a
>>> referenced by thread.h:448 (/home/tworaz/devel/genode/repos/base-hw/src/core/kernel/thread.h:448)
>>> thread.o:(non-virtual thunk to Kernel::Core_main_thread::~Core_main_thread()) in archive debug/core-hw-virt_qemu.a
>>> did you mean: operator delete(void*, unsigned long, std::align_val_t)
>>> defined in: debug/core-hw-virt_qemu.a(supc++.o)
If the code would somehow manage call such undefined symbol it'd crash.
Since I generally prefer link time failures to runtime crashes I link
all genode binaries with --no-undefined.
To fix this problem just add a dummy implementation of missing delete
operator.
Fixes#4298
Alignas should be placed before the type. Placing it after it works for
GCC, but fails when building the same codee with clang. The error
message is:
reconstructible.h:48:27: error: 'alignas' attribute cannot be applied to types
char _space[sizeof(MT)] alignas(sizeof(addr_t));

Issue #4298
Apparently the iris driver does not make use of tiling by the kernel, so
we shortcut the 'SET_TILING' call to keep iris happy with this quickfix.
However, tiling information may get lost, if the iris driver ever calls
'MMAP_GTT' and no fence is configured for the buffer. A follow-up commit
should address this shortcoming in the future.

- CPU-architecture annotations
- Change order of top-level menu, moving Mesa driver to the end
- Add black_hole, recall_fs, file_fault
- Add usb_webcam, test-capture
- Add audio driver and mixer
- Add vbox6, keeping vbox5-nova-sculpt as fallback
- Remove recall_fs launcher, which is obsolete with the recall_fs pkg
- Replace system_clock by system_clock-pc pkg

This follow-up commit to "sculpt: avoid flickering of leitzentrale"
allows nitpicker to double-buffer pixels during resize operation on a
screen size of 1920x1200.
This patch presents all press and release events to the pointer state,
fixing the problem that _key_cnt was decreased but never increased.
However, the inconsistency had no observable effects in practice.
Issue #4176
This patch extends the notion of having only one uniquely hovered client
in the presence of held keys.
If motion occurs once a key is pressed (e.g., while dragging), the
receiver of the key sequence observes the motion events. In this case,
we have to submit an artificial leave event to the originally hovered
client so that no more than one client observes itself as being hovered
at the same time. Once the key sequence is finished, the hovering is
updated again, eventually presenting a motion event to the originally
hovered client and a leave event to the receiver of the key sequence.
Issue #4176
This patch ensures that the pointer report is updated not before all
input events are handled. The change does not solve any observed
practical issue but the potential problem was spotted while reviewing
the code.
Issue #4176
To clearly identify the correct device use the unique device's name
not the type. Otherwise a driver cannot drive several devices of the
same type.

This commit contains a backport of commit [1] that deals with updating
the event ring dequeue pointer more often to prevent unnecessary
'Event Ring Full' errors.
