This patch simplifies the 'Deploy::update_managed_deploy_config'
interface by keeping an internal copy of the currently used deploy
template inside the 'Deploy' class. The template is updated whenever
the config/deploy file is modified.
This change weakens the coupling between the '_manual_deploy_rom' and
the '_deploy' subsystem, easing the upcoming implementation of the
switching between presets.
When writing the GPT header, the tool always wrote the GPT entries
belonging to the primary header to LBA following the header. Normally
this is LBA 2 as the header is located in LBA 1. The GPT allows for
up to 128 entries that all in all cover 16 KiB of storage space.
However, on some systems, e.g. ARM-based machines, the bootloader can
be stored in this region. For this reason the GPT entries may be moved
to a different LBA.
This commit changes the tool to adhere to then given GPE LBA in header
when writing out the modified GPT data.
Fixes#4720.
The old 'Io_response_handler::io_progress_response' interface has been
replaced by the 'Vfs::Env::User::wakeup_vfs_user' (issue #4697). The
remaining 'read_ready_response' method is now hosted in the
appropriately named 'Read_ready_response_handler'.

This patch keeps driving the internal state machines until no progress
can be made. This required fixing the return values of several execute
functions, which used to report progress while being in complete state.
Along the way, the patch removes default switch cases to ensure that all
states are covered.
Issue #4706
By adding a 'write_ready' interface following the lines of the existing
'read_ready', VFS plugins become able to propagate the (de-)saturation
of I/O buffers to the VFS user. This information is important when using
a non-blocking file descriptor for writing into a TCP socket. Once the
application observes EAGAIN, it expects a subsequent 'select' call to
return as soon as new I/O buffer space becomes available.
Before this patch, the select call would always return under this
condition, causing an unnecessarily busy write loop.
Issue #4697
This patch removes the 'Insufficient_buffer' exception by returning the
WRITE_ERR_WOULD_BLOCK result value instead. It also eliminates the
superfluous WRITE_ERR_AGAIN and WRITE_ERR_INTERRUPT codes.
Issue #4697
This patch fosters the batching of network packets transferred by the
lwIP stack over the NIC connection. It replaces the eager submission of
the packet-stream's data-flow signals by explicit wakeup notifications.
The commit also increases the NIC session's buffer size from 128 to 1024
packets.
Issue #4697
This patch facilitates the batching of I/O operations in the VFS library
by replacing the implicit wakeup of remote peer (via the traditional
packet-stream interface like 'submit_packet') by explicit wakeup
signalling.
The wakeup signalling is triggered not before the VFS user settles down.
E.g., for libc-based applications, this is the case if the libc goes
idle, waiting for external I/O.
In the case of a busy writer to a non-blocking file descriptor or socket
(e.g., lighttpd), the remote peers are woken up once a write operation
yields an out-count of 0.
The deferring of wakeup signals is accommodated by the new 'Remote_io'
mechanism (vfs/remote_io.h) that is designated to be used by all VFS
plugins that interact with asynchronous Genode services for I/O.

The commit "sculpt_manager: relax nic_drv policy label" introduced the use of
the "label_prefix" attribute instead of "label" for the uplink policy in the
NIC router. However, it missed an appropriate adaption of the lookup of that
attribute when the Sculpt manager has to decide which uplink is used in a
manually managed router config. This caused the uplink to disappear whenever a
user created a manually managed router config. This commit fixes the problem.

Although we do not have the full ACPI information parsed yet, to
announce non-PCI devices derived from the ACPI tables, the device
description of the assumed devices is now integral-part of pci_decode.
Formerly, the information was gained separatedly as boot-module, whereby
we lost synchronization in between ACPI/PCI parsing, BIOS handover, and
PS/2 emulation code already acting.
The platform driver configuration is missing the required 'info'
attribute that allows the 'vesa_fb_drv' to map the proper I/O
memory address of the framebuffer. In addition the driver requires
at least '2' more CAPs, so raise the quota to '110'.
Fixes#4668.
This patch makes the component graph better reusable for the phone
version of Sculpt. In the phone version, the '+' menu does not exist.
So we need to omit the corresponding button. Furthermore, the storage
dialog is presented in a dedicate section of the GUI instead of
presenting it inside the 'storage' graph node. The phone version
also does not offer the inspect view. So we need to omit the
corresponding buttons.
When using the newer genode_c_api uplink library, an uplink connection uses
the device name as label, which enables integrators to use different policies
resp. routes for different devices driven by one driver. The nic_drv policy
of the nic_roouter configuration generated by the sculpt_manager however uses
an empty label like: "nic_drv -> ". This is the way how existent NIC drivers,
like ipxe_nic_drv requested their uplink session. To support both driver
variants this commit relaxes the policy by checking for a prefix only.

If `select_from_ports` is evaluated lazily, we might miss a port during
the dependency check. A way to prevent this is to use the `:=` operator.

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.
