Implement the guest code in dedicated assembler source file, assemble
and link the binary to vmm_x86. The resulting guest-code binary
populates one page that is mapped to host the reset vector of the guest.
This approach simplifies future guest code adaption resp. extension,
e.g., to test rdmsr/wrmsr exiting.

plain_decorator_theme.tar is not linked to the app but must be generated
as side effect. Therefore, use CUSTOM_TARGET_DEPS to trigger the
generation.
Fixes#4637
This reverts commit 9a37ccfe29 except for the
new declarations in public headers (in order to not change any APIs again).
We revert the commit as we found that there are corner cases in which it
produces a bad UDP checksum. The bad UDP checksum was observed via Wireshark at
a TFTP server in a Sculpt 22.10 Debian 11 VM on the first request of fetching a
file with the TFTP client of the uboot on our iMX8 test board.

According to OpenBSD's azalia driver some AMD HDAudio devices do not
play nice with MSIs although the capability is set. At least the
0x1457 device was tested and worked using GSIs only.

During initialization _handle_link_state may be called concurrently from EMT and
"nic_ep" (signal handler). Therefore, sent signal to "nic_ep" instead of calling
_handle_link_state from EMT thread.
issue #4632
Some DHCP clients (Debian VM in Sculpt) persistently store the last lease they
obtained and try to directly DHCP REQUEST it on a new startup whithout doing
DHCP DISCOVER beforehand. In case the NIC router doesn't know about the lease
anymore (timeout, new router instance), the router used to just ignore the DHCP
REQUEST. This led to significant delays in the network startup of the client
(delayed retries until give-up and DHCP DISCOVER). With this commit, the router
answers such packets with a DHCP NAK instead, causing the client to directly
switch to DHCP DISCOVER.
Fixes#4634
This patch removes the intermediate querying of the depot while the
installation of packages is in progress. This avoids misleading warning
messages and reduces superfluous file-system load during the
installation of large packages.
Issue #4631
On-demand initialization prevents read-write operations on BARs of
invalid devices at construction time, which may result in surprising
behavior later on, for example, when resetting X260 notebooks via ACPI
information.
These utilities simplify the control of clocks, resets, and power
domains from within the platform driver.
This is needed when driving a low-level device directly from the
platform driver, for example for driving the mbox mechanism to access
the system-control processor of the PinePhone.
This patch reflects both the pci_decode results and the platform
driver's aggregated device information in Sculpt's /report/drivers/ in
the form of pci_devices and devices files respectively.
The configured 'st_blksize' influences the sizing of the FILE buffer,
see '__swhatbuf()'. Increasing the blksize hint can lead to larger
'fread()' requests and in return to fewer roundtrips.
This commit updates the driver from version 6.6 to 7.1. In contrast
to the old driver the new one will now probe all available HDA devices
and will drive the first usable one, e.g.:
```
[init -> audio_drv] azalia0 [8086:160c]
[init -> audio_drv] :
[init -> audio_drv] azalia0: no supported codecs
[init -> audio_drv] azalia1 [8086:9ca0]
[init -> audio_drv] :
[init -> audio_drv] azalia1: codecs: Realtek ALC292
[init -> audio_drv] audio0 at azalia1
```
Fixes#4629.
Implemented as depicted in the OpenBSD driver, register description
found in 'AMD SB700/710/750 Register Reference Guide'
(43009_sb7xx_rrg_pub_1.00.pdf).
Issue #4629.
Instead of using a global value to enumerate the MSIs, use a function argument
instead. Whenever the process of PCI device reporting gets started again,
due to an initially too small report buffer, the MSI enumeration value is reset
again. Formerly, we wasted MSI numbers.

Don't skip IRQ reporting if legacy IRQ/GSIs are not supported as the
device may support MSI/MSI-X exclusively.
The commit also enables reserved_memory reporting of devices without
IRQs.

Until now, the /config/system ROM was not handled by the sculpt manager
but solely managed by the user. Its main purpose was the ability to
reset or power-down the machine by manually modifying the 'state'
attribute. However, down the road, we'd like to enable the sculpt
manager to drive this state, e.g., to implement the multi-staged
loading of drivers, or to drive suspend-resume states.
The support such scenarios, the 'system' state has been moved from
/config/system to /config/managed/system.
* Add EHCI PCI quirk
* Add UHCI reset to UHCI quirk
* Apply all PCI quirks in order of the PCI bus numbering
otherwise the machine might stall
