4b983f92c5 lx_emul: support execution till condition applies
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.

2fd2b7d628 lx_kit: map I/O mem with proper offset
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.

0d163915d0 nova: avoid hangs on AMD with IOMMUs
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.

7d6c592417 vfs/rump: handle split block I/O jobs
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.

a45aabe68c usb_block: handle block requests in Signal_handler only
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.

4dbe1588a6 sculpt: relax heartbeat rate
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

b9141f98af test/black_hole: fix "packet alloc failed"
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.

78d7a08618 wm: hide child views if top-level view vanishes
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.

df1767b784 vbox6: tidy up devxhci poweroff

smart-card readers. If the VM is powered off, PDMR3Term cleans up all

ef8c98cb71 nic_router: merge packet stream signal handlers
The NIC router used to handle each type of packet-stream signal with a distinct
method in the Interface class. However, merging those methods has advantages.

It ensures that sent packets that were already acknowledged by the counter side
are always released before handling received packets. This frees packet stream
memory which facilitates the potential allocation of response packets while
handling received packets. Furthermore, it simplifies the code and reduces the
number of entry points into the router.

This commit also removes the installation of signal handlers at packet streams
for events that are of no interest for the router (TX-ready-to-ack /
RX-ready-to-submit at NIC sessions and RX-ready-to-ack / TX-ready-to-submit at
Uplink sessions).

7fc20e9ae8 NIC router: update IP config on DHCP RENEW/REBIND
The NIC router did update the IP config of a domain on a completed DHCP
REQUEST but not on completed DHCP RENEW or DHCP REBIND. Thus, it didn't adapt
to "real" DHCP servers (not NIC router servers) that got restarted with a
changed configuration by the means of RENEW/REBIND. The commit fixes this.
Note, that testing this is complicated as we don't have the necessary
infrastructure (we cannot simply use the DHCP server of the NIC router as this
would apply a link down/up sequence in order to let the client restart DHCP)

da1ef67064 base: Allocator_avl cleanup meta data
After reverting unused ranges during allocator destruction
'_meta_data.free_empty_blocks' may lead to more unused ranges because
meta data blocks maybe freed where the meta data for the blocks is
managed by other meta data blocks. This leads to dangling allocation
warnings which are caused by meta data. Therefore, we call
'_revert_unused_ranges' and 'free_empty_blocks' until no more ranges
can be freed.

664676a2b4 intel/gpu: support 64bit pci bars
by using the io_mem RPC of the platform session instead of parsing the
bar resources manually. This commits avoids and breakage on systems where
the Intel graphic cards just uses 64bits with addresses above 4G.

410099df70 base/memset: speedup implementation
Compared to the bytewise memset, a wordwise memset (or even multi-word)
achieves a speedup of ~6.

On Zynq-7000/Cortex-A9:
317 MiB/s -> 2040 MiB/s

On base-linux x86_64:
3580 MiB/s -> 23700 MiB/s

0104a74028 memcpy (arm): cache align and use pld for speedup
Preloading a few cache lines ahead brings a significant speedup in
memcpy throughput. Note, the particular (optimal) value was empirically
determined on a Cortex-A9 (Zynq-7000) SoC @ 666Mhz. It is best combined
with L2 prefetching enabled (including double linefills and prefetch
offset 7). Yet, even without L2 prefetching this seems to be the sweet
spot.

4dcc095e5e memcpy (arm): remove unused vfp implementation
The implementation is not in use any more. Furthermore, on typical ARM
cores such as the Cortex-A9, the cached read appears to be the
bottleneck rather than instruction density. On a Zynq-7000 SoC, the vfp
implementation performed significantly worse than the standard load/store
multiple implementation with preloading.

07736d1689 test/memcpy: fix optimistic results on Linux
When executed on Linux, the test was impaired by the copy-on-write
optimisation since the source buffer was never initialised. By default,
Linux only maps a zeroed page until the first write access to the page
occurs. Since the source buffer was never written, the corresponding
page was always present in the physically-indexed data cache. In
consequence, the test merely measured write performance (similar to memset).

Our usb_host driver supports UHCI, OHCI, EHCI, and XHCI host
controllers. The USB4 host interface / Thunderbolt is currently not
supported and must therefore not be passed to the USB host driver.
