Remove handling of ACPI (SCI) interrupt from kernel and thereby let the
handling of the ACPI irq exclusively to an Genode driver. On Genode the ACPICA
library+app handles the ACPI irq, where we can now remove the contrib patches
related to the synchronization between NOVA kernel and ACPICA library.
Fixes#4479
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).

Send usb ctrl transfers with one second timeout as some devices (e.g.,
smartcard readers) do not response to certain control transfers.
Thanks to Peter for the investigation.
Upgrade to the well known worst cases by the GPU multiplexer. Do not
keep track of resources locally, in case resources are exceeded the
remain so anyway.
issue #4451
First, the endpoint update has to comply with the current alternate
settings of all interface, which are stored in USBDevice::altsetting[]
(one value per interface). Second, a SET_INTERFACE control request via
Packet_type::ALT_SETTING must update USBDevice::altsetting for the
interface.
Now, USB devices with multi-setting interface like the Joulescope JS110
with mixed bulk/isochronous endpoints are supported.
The run script uses core, ld.lib.so, and init from depot packages, thus
these cannot be integrated in the image explicitly from the build
directory.
Also, removed special build of report_rom, which is not subject of the
test.

* Switch from the legacy usb_host driver to the new PC version
in recipes and automated tests
* Update documentation snippets
* Remove outdated, unused usb_rndis run-script
Fixgenodelabs/genode#4416
XML allows attribute values like <node attr="\"/>. The XML parser
wrongly reflects this case as 'Invalid_syntax'. This behavior stems from
the implicit use of the 'end_of_quote' function, which considers the
sequence of '\"' as a quoted '"' rather than the end of a quoted string.
The patch solves this problem by making the 'end_of_quote' part of
the tokenizer's scanner policy.
The patch removes the 'end_of_quote' function from 'util/string.h'
because it is not universal, and to avoid the ambiguity with
'SCANNER_POLICY::end_of_quote'.
Fixes#4431
To make room for the re-newed usb_host_drv basing on Linux 5.14 and
the re-newed lx_kit/lx_emul we have to move the depot recipe and
consistently name the old drivers with a legacy_ prefix.

In the error case of socket_fs_accept() the Unconfirmed utility was

Fixes#4406
The 'read' and 'write' utilities are from a time before the VFS API
as os/vfs.h was available. They rely on the (now removed) blocking
semantics of the packet-stream interface.
The only remaining legitimate use case of the direct interaction with
the file-system session without VFS is the back end of gcov, which needs
a way to exfiltrate the statistical data using a channel that is
independent from the libc or the VFS.
Issue #4390
Do not import a freshly allocated buffer to all contexts eagerly.
Instead check buffer list in context's 'exec_buffer' call and import
only buffers needed and not present before GPU execution. This leads to
improved performance for applications that use many OpenGL contexts
(e.g., VirtualBox 6).
issue #4380
Retrieve multiple GPU sessions from VFS plugin, take advantage of buffer
import/export functionallity in order to implement gem context support.
Multiple contexts share all GPU buffers, but use different GPU sessions
and thus, differnt page tables and hardware contexts.
issue #4380
Synchronize GPU completion by calling 'read' of the vfs_gpu plugin. This
enables pthreads to wait for GPU completions instead of the main EP.
issue #4380
* let iris handle buffer management, this implies that BOs are mapped to
the PPGTT during buffer execution and unmapped by iris later, for this
to work buffers need to be unmapped when allocating cached BOs
(vma_free) which requires a patch
* support lseek (drm_lseek for now) for determining object size
issue #4380
Only parse output of the test programs one-by-one and ignore log
messages from other components not starting with '[init -> test$number]'.
Fixes sporadic failures on KERNEL=sel4 due to the following warning from
core.
Warning: flush page table entries - mapping cache full - PD: init -> test1
The socket type (in the lower bits) maybe ORed with SOCK_CLOEXEC and
SOCK_NONBLOCK options (in the higher bits). Currently, supported values
are SOCK_STREAM (1) and SOCK_DGRAM (2), so just take the lower 2 bits.
This fixes treating `SOCK_STREAM` sockets as UDP if additional flags
were set.
Fixes#4370
The path for the `nameserver` file was fixed to `/socket/nameserver`.
So, if the socket directory was configured differing from `/socket`, DNS
did not work. Now the default path for the `nameserver` takes into
account the path configured in the `socket` libc config attribute.

Since the parts of the 'etnaviv' library are already part of the
'mesa.lib.so' that is normally loaded along-side remove the
duplication here.
Issue #4329.
This patch changes the 'Allocator' interface to the use of 'Attempt'
return values instead of using exceptions for propagating errors.
To largely uphold compatibility with components using the original
exception-based interface - in particluar use cases where an 'Allocator'
is passed to the 'new' operator - the traditional 'alloc' is still
supported. But it existes merely as a wrapper around the new
'try_alloc'.
Issue #4324
This patch replaces the 'Ram_allocator::alloc' RPC function by a
'try_alloc' function, which reflects errors as 'Attempt' return value
instead of an exception.

Always instantiating a network device with id `net0`, removes the need to call
append_qemu_nic_args in run scripts unless we want to add forwarding
rules.
genodelabs/genode#4311
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.
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
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.
Issue #4284
The new 'Env::try_session' method mirrors the existing 'Env::session'
without implicitly handling exceptions of the types 'Out_of_ram',
'Out_of_caps', 'Insufficient_ram_quota', and 'Insufficient_cap_quota'.
It enables runtime environments like init to reflect those exceptions to
their children instead of paying the costs of implicit session-quota
upgrades out of the own pocket.
By changing the 'Parent_service' to use 'try_session', this patch fixes
a resource-exhaustion problem of init in Sculpt OS that occurred when
the GPU multiplexer created a large batch of IO_MEM sessions, with each
session requiring a second attempt with the session quota upgraded by
4 KiB.
