This patch fixes rare freezes of menu view instances, which could happen boot
time whenever the leitzentale GUI happens to get initialized before the display
driver finished setting up a reasonable mode. In this case, the resolution-
dependent font size can temporarily get almost zero, tripping up the glyph
renderer.
Since the driver relies on all requests being Nvme::MPS_LOG2 aligned
as advertised in its Block::Info the added check will reject any
misaligned requests (using 'gpt_write' led to an IOMMU write fault).
Issue #4486.
2560x1440 resolutions require more RAM resources. Additionally, make
sure that the decorator 'init' receives enough CAPs to service the
decorator configuration.

* When releasing interfaces, wait until all

In rare cases it is necessary to execute Linux contributed code
until certain work is finished, e.g. when in a synchronous RPC call,
a session construction or destruction a result is needed. Therefore,
we introduce a new lx_emul function called lx_emul_execute_kernel_until.

To signal that a device gets used and released by a session
introduce claim, release, and release all callbacks in the
USB interface of the C-API.

In case multiple devices shared the same memory-mapped I/O page
we have to take the offset into account. This commit fixes the
'pc_usb_host_drv' on the Thinkpad X201 where the two EHCI host
controller share the some I/O memory page.
Fixes#4477.
With the new usb driver #4399 and usage of the updated dde_linux lx_eml/lx_kit
approach a much higher rate of IRQ session construction/destruction and signal
handler assignment (irq->sigh) are caused. This trickles down to the kernel,
which causes an hang of the AMD IOMMUs due to not setting reserved bits
adequately. The commit fixes the root cause in the kernel and add a guard
into core's to limit such driver behaviour.
Fixes#4482
The file listed only enabled="false" in the audio adapter tag. However,
setting only this option to true isn't sufficient for guest audio to work.
One has to set also enabledIn respectively enabledOut in the same tag. The
new default vbox6 file reflects this.
Fixes#4476
This patch fixes a potential data corruption issue that could occur when
issuing large I/O requests to vfs/rump, which don't fit into the default
block I/O buffer of 128 KiB. Note that we haven't observed the problem
in practice (Sculpt hosts vfs/rump in a dedicated vfs server, which
fragments requests) but spotted the issue while reviewing the code. We
could trigger problem by explicitly changing the I/O buffer size to 32
KiB.
Issue #4474
This patch changes the meaning of the 'offset' parameter of the
'produce_write_content' and 'consume_read_result' hook functions.
The value used to reflect the absolute byte position but in practice,
a job-relative byte offset is desired.
Issue #4474
Before this commit, the block-request handler was implemented as
Io_signal_handler and, additionally, the USB driver called the
block-request handler on request completion directly on I/O level. This
is generally a bad idea because I/O handlers should avoid to have direct
global side effects. In contrast, application logic should be
implemented in way that it consumes atomic state changes after I/O
completed. Now USB I/O completion locally submits a signal to the
block-request Signal_handler.
This patch reduces the response time of supposedly stuck situations like
an unresponsive part_block component. First, it reduces the heartbeat
rate from 1 to 2 seconds to make it consistent with the frequency of
state reports. Second, it allows up to four skipped heartbeats until
regarding the situation as stuck. With those changes, the prolonged
initialization sequence of a USB ZIP drive succeeds with Sculpt.
The Uplink_test used to end in an uncaucht exception about a failed packet
allocation on several x86_32 platforms.
* Destruct and re-construct the corresponding TX packet allocator during a
link-down-up step in the Uplink test. Fixes the exceptions but results in a
never ending test.
* Decouple the link-down-up steps from the handling of packet stream signals
by simply triggering it with a local periodic timeout of 1 sec period.
This prevents that the Uplink_test never finishes because it destructs the
Uplink connection too often.
* The test finishes not before at least 3 link-down-up steps were executed.
* Replace the Allocator_avl's used for the TX packet allocators of the Nic
and Uplink Connection with the better suited Nic::Packet_allocator.

The error message
"Command buffer creation failed" in intel_dsb.c repeatedly appears
during connector hotplug. Since the driver works also without this DMA offload
optimization, disable the functionality.
Issue #4450
The service is merely announced but trying to request a session always causes a
Service_denied exception. This helps in scenarios where the client is
won't open a session anyway but expects the service to be available. This is
considered a temporary solution.
Ref #4419
This patch handles the corner case of switching virtual desktops while
child views are visible. Examples of such child views are tool tips,
pull-down menus, or the graph of the top-view utility. The switch to
another virtual desktop would implicitely turn the child views into
top-level views of the root nitpicker GUI server until switching back
to the original virtual desktop.
The patch implements the expected behavior of hiding all child views
that belong to a disappearing top-level view.
As it stands, the implementation requires minimal reflection measures to
implement correct cleanup procedure. static_cast<> cannot be used as it
does not implement runtime type casting as dynamic_cast<> does.
This patch reverts the vfs-watch-handle creation whenever the subsequent
allocation of the VFS server's 'Watch' object fails. This can happen
when the session RAM or cap quota is depleted.
Fixes#4472
The issue came apparent with Windows Guests and USB passthrough of
smart-card readers. If the VM is powered off, PDMR3Term cleans up all
devices incl. (first) acpi and (later) devxhci. The latter used a
dangling reference to ACPI structs in a indirect call to
apicIsLogicalDest() from xhciR3Destruct().

The fix removes our Qemu library reset from xhciR3Destruct() and
registers xhciR3Reset() as PowerOff hook.
Thanks to Raphael for the thorough investigation.
The quota adjustments prevent the leitzentrale's decorator from running
out of RAM, and allow the nitpicker GUI server to preserve buffer
content during resize (reducing flickering artifacts) when using a
screen resolution up to 2560x1440.
