By adding a 'report' node to the platform driver's configuration
one can enable either devices or config reports. The devices
report contains all devices and their detailed state, as well as
whether it is already in use or not. The config report contains
one by one the current configuration of the platform driver.
Moreover, this commit adds a README file describing the facilities
of the platform driver.
Fixgenodelabs/genode#4386
If PCI devices happen to miss complete configuration after boot, the
platform driver supports <pci-fixup> nodes for concrete devices
(specified by bus-device-functions tuples). The
<bar> node instructs the platform driver to remap BAR id 0 to address
0x4017002000, which amends the BIOS configuration and is stringently
required for BARs with address 0.
! <pci-fixup bus="0" device="0x15" function="3">
! <bar id="0" address="0x4017002000"/>
! </pci-fixup>
The issue was discovered with Intel LPSS devices in Fujitsu notebooks.
Fixes#4501
This patch changes the libc to query the stack size from the
config attribute <libc> <stack size=""/> </libc> for regular
components, not only cloned processes.
To discharge the generic platform driver from certain PCI bus scanning,
and ACPI + kernel specifics, this commit introduces a new component,
which consumes the acpi drivers report and the platform_info from core
to prepare a devices ROM for the platform driver that contains all
PCI devices and its resources.

USB Attached SCSI devices might expose a bulk-only interface
as fall-back at interface 0 and alternate setting 0. This commit
allows for probing all alternate settings of the active interface
to be able to use such devices.
The configuration was extended so that in case the device interface
is known beforehand the driver can be configured accordingly.
Fixes#4494.
Deploying an overly large meta-pkg in Sculpt leads to an
'Xml_generator::Buffer_exceeded' exception. Using the expanding
reporter solves this problem.
Fixes#4493.
In case we are instructed to reauthenticate and were already
authenticated we ignore the request in the management layer
and let 'wpa_supplicant' deal with that.
Fixes#4488.
The vanilla NOVA kernel solely supports tracking and exporting of execution
times per SC kernel object, but not per thread (EC object). The commit extends
to track execution times per EC in the NOVA kernel, exporting it to Genode's
'core' roottask and populating Genode's Trace::Subject_info structure.
Fixes#4481
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 using the framebuffer driver on this machine the
'cpu_latency_qos_request_active' dummy is triggered. Removing the
trace-and-stop call makes the driver usable.
In addition, 'cpu_latency_qos_remove_request' is changed as well
although it is guarded by 'cpu_latency_qos_request_active'.
Fixes#4489.
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.

* Claim and release USB interfaces
* Collect URBs in flight in anchor list
* When releasing interfaces, wait until all
anchored URBs finally got killed successfully

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.
