If any PCI device reports 0 as interrupt PIN, drivers may try to force
MSI setup (e.g., xhci). So, we clamp the interrupt PIN to 1 to let
drivers finish initialization and don't bother the platform driver.
Encountered on the Fuji5 where for reasons currently unknown the
first xHCI HC (0:0d.0) could not be initialize due to incomplete
interupt informations. The other HCs appear to work fine (tested
with a USB low-speed mouse).
This commit removes all physical notions from the information given
to the Linux kernel regarding PCI BARs.
With the exception for the host bridge that needs to be located at
'0:00.0' as required by the Intel FB driver, all other devices are
announced at the PCI BUS in an ascending order.
Additionally the MMIO regions start at 1 GiB and are capped at 32 bit
to prevent unnecessary access to 64 bit addresses.
With this fix, the driver no longer aborts on the Tigerlake notebook and
just skips the out-of-region ACPI table. Issue #4452 is not fixed by
this commit, but in this specific case the table is not used anyway.
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
Check if there are a least 4 caps + 2MB (heap) + possible buffer size
available before any resource allocation. Only account resources that are
actually used.
issue #4451
Some devices do not answer connection attempts timely, which leads
amtterm to time out (after 60s). Using multiple attempts in 500 ms
intervals results in timely connection and complete boot logs.
Issue #4429
The former implementation relied on the behaviour of how the old
intel fb driver requested the pci devices. The new lxkit however actually
really want to have all available pci devices.

required by the upcoming update of the intel display driver. Make this addition
explicit, because it triggers adjustment also on the new pc_usb_host_drv.

This patch adds the trace-logger utility to the default set of packages
along with an optional launcher. With this change, only two steps are
needed to use Genode's tracing mechanism with Sculpt:
- Add 'trace_logger' to the 'launcher:' list of the .sculpt file
- Either manually select the 'trace_logger' from the '+' menu,
or add the following entry to the deploy configuration:
<start name="trace_logger"/>
By default, the trace logger is configured to trace all threads
executed in the runtime subsystem and to print a report every 10
seconds. This default policy can be refined in the launcher's <config>
node. Note that the trace logger does not respond to configuration
changes during runtime. Changes come into effect not before restarting
the component.
Issue #4448
This patch changes the output format of the trace logger to become
better suitable for human consumption. For example, when instrumenting
the VFS server in Sculpt using the GENODE_TRACE_TSC utility, the
trace logger now generates tabular output as follows.

Subjects that belong to the same PD are grouped together. The formerly
optional affinity and activity options have been removed. Those
information are now unconditionally displayed. The trace entries
belonging to a thread appear as slightly indented.
The patch also updates the coding style, avoiding excessively long
lines.
Issue #4448
This patch reduces repetitive log output by omitting inactive trace
subjects from the log output. The information about all subjects can
still be dumped by setting 'verbose="yes"'.
Issue #4448
This patch splits the creation and updating of monitor objects into two
stages. The creation of a monitor object changes the state of the
associated trace subject. The patch ensures that the new state is
captured by the update of the monitor object.
Issue #4448
This patch makes the trace-subject state as reflected to the trace
monitor more accurate.
Until now, a subject could be in UNTRACED or TRACED state. In reality,
however, there exists an intermediate state after the trace monitor
called 'trace' for the subject but before the subject locally activated
the tracing (done when passing a trace point). This intermediate state
was reflected as UNTRACED. Consequently, threads that never pass a trace
point (e.g., just waiting for I/O) would remain to appear as UNTRACED
even after enabling its tracing by the trace monitor. This is confusing.
This patch replaces the former UNTRACED and TRACED states by three
distinct states:
UNATTACHED prior any call of 'trace'
ATTACHED after a trace monitor called 'trace'
but before the tracing is active
TRACE tracing is active
Fixes#4447
The new macros GENODE_TRACE_TSC and GENODE_TRACE_TSC_NAMED complement
the existing GENODE_LOG_TSC and GENODE_LOG_TSC_NAMED macros to simplify
TSC measurements at a low overhead of the trace mechanism.
The utilities of the new util/formatted_output.h header complement the
existing base/output.h with the text-formatting support needed to
produce tabular output.
Fixes#4449
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.
This commit adjusts the value such that USB sessions requested by
VirtualBox6 on Sculpt OS can get established on the first try without
invoking the session-retry mechanism. This reduces the number of
diagnostic log messages like:
Error: Insufficient 'ram_quota',got 6296372 need 6297928
The value of 50% as assigned by commit "sculpt: add basic support for
i.MX8 Quad EVK" leaves too little room for other components of the
runtime subsystem. With the adjustements of commit "sculpt: assign CPU
quotas" the sum exeedcs 100%. Hence this commit tunes down the value to
sensible 10%.
The existing assignment of CPU quotas did not anticipate the dynamic
reconfiguration of init. It merely tracked the available CPU quota by
deducing the consumed amount from a global variable but never
replenished the value. This worked for static scenarios but failed in
situations where components are dynamically re-started.
So far this deficiency remained detected because CPU quotas were not
used in highly dynamic systems like Sculpt OS. However, this has
recently changed by commit "sculpt: assign CPU quotas".
The patch improves the accounting by mirroring the existing handling of
RAM and cap quotas. Note that the CPU-quota accounting is still rather
limited. In particular the dynamic rebalancing is not yet supported.
Issue #4445
.SHELLFLAGS is extended by option pipefail to make pipes fail if any pipe
element fails. As .SHELLFLAGS is exported into sub-make instances it
must be unexported before calling third-party build systems recursively.
