0bc5bcce4a test/driver_time: fix page-fault of ARMv8a variant
The get_cycles() call within the test doesn't apply to RDTSC
access when running on ARM but to arch_timer_read_counter, which
is an empty function pointer. By setting it to a function that
returns Genode::Trace::timestamp() we can enable the test for ARM.

f7b910b298 part_block: split reporting from parsing
Previously the 'partitions' report was implicitly generated after
parsing the partition-table by accessing the referenced reporter
object.

Now the report is explicitly created by calling the 'generate_report'
member function. At this point we no longer have access to all
required information so the 'Partition' class was extended to
accommodate for the data needed by MBR as well as GPT reports.

fd7001d020 os/vfs.h: don't truncate File_content
The 'File_content' utility throws an exception whenever a file happens
to get truncated during the reading process. But it silently truncates
the data against the specified limit. In practice, exceeding the limit
is usually an error case. This patch enhances the 'File_content' utility
by throwing 'Truncated_during_read' in the limit-exceeded case as well,
in order to ease the diagnosis of such cases.

61926ebc07 base: introduce platform_init function
The new 'init_platform' function performs the platform-specific
component-local low-level initialization. It allows for the
differentiation between core and regular components as well as
kernel-dependent peculiarities.

This patch introduces a consistent notion of a 'Platform'. Within core,
the 'Platform' contains the kernel-specific initialization. Outside
core, the platform sets up the interplay with the parent component. In
all cases, the platform is constructed while running on the initial
stack.

ae0e0c118e nvme_drv: add support for host-memory-buffer
This commit introduces support for the HMB feature and will setup the
buffer during start-up. The host-memory-buffer (HMB) feature is mostly
used on NVMe devices that do not make use of an DRAM cache to store its
translation tables amongst other operational data. Not using HMB can
impair the performance on such devices.

The memory is allocated in 2 MiB chunks of DMA-capable memory and its
total size in bytes is configurable via the 'hmb_size' config attribute.
The driver always checks the minimal and preferred size of the HMB and
issues a warning in case it is not enabled via the configuration.
Moreover, if the configured size is less than the minimal amount
required by the device the HMB is not configured at all and a warning
is issued also. If the configured size is more than the preferred size
it will be capped to that amount.

50541c68ec lx_emul: shadow cpu_relax to update jiffies
There are rare use-cases where cpu_relax is used inside a busy loop
(i2c bus functions), which only will break when the jiffies counter
reaches a specific value.
Because of the cooperative scheduling done in lx_emul, no timer
interrupt will break such a loop. As a workaround, we check for
necessary jiffies updates inside cpu_relax if interrupts are enabled.

adc594a7e6 os: remove conversion warnings/errors from virtio
The read_config and write_config functions in the generic virtio
headers used by all drivers lead to compiler warnings resp. errors
if effective-c++ switch is enabled. Moreover, the functions require
to define the access width as parameter. We can better turn them
into template functions using the value type to read resp. write to
derive the access width.

bdf47785b8 vfs: remove 'file_size' from read/write interfaces
The 'file_size' type denotes the size of files on disk in bytes. On
32-bit architectures it is larger than the size_t, which refers to
in-memory object sizes.

Whereas the use of 'file_size' is appropriate for ftruncate and seek, it
is not a suitable type for the parameters of read/write operations
because those operations refer to in-memory buffers.

This patch replaces the use of 'file_size' by size_t. However, since it
affects all sites where the read/write interface is uses, it takes the
opportunity to replace the C-style (pointer, size) arguments by
'Byte_range_ptr' and 'Const_byte_range_ptr'.

6e1517ca3c libdrm/lima: introduce disjunct contexts
Prior to this change the libdrm Lima implementation supported the
creation of multiple contexts where each context, however, was

With this commit each context becomes its own client while the
main context always performs all buffer object related allocation
and the other context import each needed BO before submitting.

677c8e828c depot_download,depot_query: support system images
This patch enhances the depot_download subsystem with support for
downloading and querying system images.

The installation ROM support the following two now download types:

  <image_index path="<user>/image/index"/>
  <image       path="<user>/image/<name>"/>

Internally, the depot-download subsystem employs the depot-query
component to determine the missing depot content. This component
accepts the following two new queries:

  <images      user="..."/>
  <image_index user="..."/>

If present in the query, depot_query generates reports labeled as
"images" and "image_index" respectively.

The also tracks the completion of each job depending on the depot-
query results, so that the final report contains a result for each
installation item requested. Prior this patch, the inactivity of the
depot-download manager (indicated by an empty state report) was
interpreted as success. But that prevents the proper association of
results and requested installation items.

operation instead of VFS-internal I/O buffer sizes. This relieves the

3447d0ccb9 menu_view: avoid flicker when enlarging the view
Each time when enlarging the menu view, a new 'Gui_buffer' is
constructed with the new size. At its contruction time, the default
reset background color is in effect, which is evaluated by
'reset_surface' as part of the construction. A custom reset color
takes effect only after the construction. Hence, when the Gui_buffer is
flushed to screen immediately at construction time, the gray default
becomes visible for a short time.

This patch changes the Gui_buffer to accept the reset background color
as construction argument so that it takes immediate effect.

d33139c40a enable ccache for reference Linux kernel
Genode build system allows to easily enable 'ccache' for builds. This
change allows to enable using 'ccache' also for build of reference
Linux kernel used during porting device drivers.

To enable 'ccache' it is enough to pass value of 'CC' variable when
executing Linux build but this build by default depends on time when it
is built which causes 'ccache' misses. To solve this issue additional
flags are passed to make build independent from time, current user and

5f0ba7d722 intel_fb: handle rapid config change gracefully
In case of very rapid config ROM change (<300ms), the linux driver may still
be in progress of applying the previous change (e.g. switching connector on/off).

During this progress all tasks may become not runnable (waiting for IRQ/timeouts
until hardware state settles), the newest config ROM change/signal gets
dispatched, which lead to continuing the previous change request, but not
to re-starting/re-applying the new config change. To avoid this situation,
explicitly track whether a previous config change was finished and track if an
interim config change request came in. If so, re-start the lx_user
task with the newest config change.

20fea7fdd2 base-hw scheduler test: adapt to new behavior
This adapts the test to the changes that were applied to the scheduling scheme
by the following commits:

* base-hw scheduler: optimize quota depletion events
* base-hw scheduler: fix bug on removing head
* base-hw scheduler: fix ready method
* base-hw: optimize & cleanup scheduler

Part of that is that the test used to check whether the act of setting a share
ready outdates the head or not. However, with the current version of the
scheduler, this check is not possible anymore. We can merely check whether the
head is outdated after setting the share ready. So, among other adaptions, this
commit adapts the expectations of the test to the new semantics of the check.

0467b4aaf3 base-hw scheduler: optimize quota depletion events
This is an optimization for the case that a prioritized scheduling context
needs slightly more time during a round than granted via quota. If this is the
case, we move the scheduling context to the front of the unprioritized schedule
once its quota gets depleted and thereby at least ensure that it does not have
to wait for all unprioritized scheduling contexts as well before being
scheduled again.

Note that this introduces the possibility of undeserved starvation of
unprioritized scheduling contexts to the scheduling scheme. If there are
enough prioritized contexts that deplete their quota during a round,
they may cover up also the rest of the round with their unprioritized time
slices. If this happens every round, contexts without a priority/quota may
never get a turn. In the previous scheduling scheme, this could not occur as
the unprioritized schedule was completely independent from prioritized
schedules and rounds.

fc690f1c47 hw: re-work the ipc node's internal state machine
* Split the internal state into incoming and outgoing message relations
* Avoid fragmenting of one state like formerly '_state' and '_help'
* Remove pointer to caller, use incoming FIFO instead

This commit fixes at least two bugs that were triggered by tests that
destroy threads in many different states, like run/bomb:

* The '_help' data member was not reset reliable in each situation where a
  helping relationship came to an end. However, when we fixed this bug alone
  in the old state model, the issues remained. The new state model fixes
  this bug as well.

* A thread sometimes referenced an already dead thread as receiver. This caused
  the kernel IPC code to access the vtable of an object that didn't exist any
  longer. Note that the two threads were not in direct IPC relationship while
  the receiver was destroyed, so, there must have been an intermediate node
  between them. Due to the complexity of this problem, we eventually gave up
  pin-pointing the exact reason in the kernel IPC code. The issue disappeared
  with the new state model.

5a558a64e1 gpt_write: use GPE LBA from header
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.

1b1a9ca95c nic_router: fix bad connection states on IP change
When a domain receives a new dynamic router IP address and that domain has
active connection states (TCP/UDP/ICMP) from another domain with NAT applied,
the connection states used to stay active while becoming obsolete. They
become obsolete because their identification and their packet processor
use the old routers IP address due to NAT.

One consequence was that connections became dysfunctional when the server
domain received a new dynamic router IP address. Request packets were still
routed from client to server, but when entering the server, their source IP
address was the outdated router address. Consequently, the server responses
used the outdated address as destination and the router dropped the responses
because it did not know this address anymore.

This commit fixes the problem by letting a domain destroy all its connection
states that were initiated from within other domains whenever it detaches from
its current IP configuration.

Strictly speaking, it is not necessary to destroy all connection states, only
those that the domain applies NAT to. However, the Genode AVL tree is not built
for removing a selection of nodes and trying to do it anyways is complicated.
So, for now, we simply destroy all connection states.

Note that the other way around was handled correctly already. When a domain
detaches from its IP config, all interfaces of that domain destroy all the
connection states they created (towards other domains).

ff2176a586 vfs,libc: support write fds in select
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.

5ad98f2b7c vfs,libc: introduce Vfs::Env::User interface
The new interface is meant to replace the 'Vfs::Io_response_handler'.
In contrast to the 'Io_response_handler', which had to be called
on a 'Vfs_handle', the new interface does not require any specific
'Vfs_handle'. It is merely meant to prompt the VFS user (like the libc)
to re-attempt stalled I/O operations but it does not provide any
immediate hint, about which of the handles have become ready for
reading/writing.

0584ac195c curl: increase maximum write-buffer size
The original size of 16K impedes the batched processing of network
packets. Changing the value to 256K reduces the number of context
switches when downloading large files and thereby improves the
throughput by more than 25% (base-hw on qemu_x86_64, using fetchurl
to download a file of 100 MiB via the NIC router from lighttpd).

This patch fosters the batching of network packets transferred by the

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

fcf5fcd58c libports: remove stand-alone variant of lwIP
Since the lwip library is used only by the vfs_lwip plugin, this patch

further simplification and allowing for a tighter integration with the
VFS plugin.

The recipes for api/lwip and src/vfs_lwip stay separate as both parts
use different licenses.

7d8d4f4532 vfs,libc: deferred wakeup of remote peers
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.

9421a449ab test/libc_many_writes for examining write batching
This test reveals the patters of the batching of consecutive write
operations on a file-system session. It issues 100 writes of one byte
each, which should ideally result in large batches of operations
submitted to the file-system session at once.

The run script performs the write operations through a chain of two VFS
servers, thereby exercising the write batching of both the libc and the
intermediate VFS server.

6edede0db9 server/vfs: facilitate batching of requests
By replacing the calls of 'acknowledge_packet' and 'get_packet' with
'try_ack_packet' and 'try_get_packet', we avoid the implicit triggering
of data-flow signals. Instead, the VFS server now relies on explicit
calls of the packet stream's 'wakeup' interface.

The cause was the use of Signal_context::local_submit() in the libc

in combination with a missing context-mutex aquisition resulting in a

f10c470969 sculpt_manager: fix router label lookup
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.

b596db3eed pistachio: size-aligned I/O mem mapping in core
This commit circumvents faulty behaviour of base-pistachio, if
the PCI config space gets requested megabyte-wise. It occurs that
we get a mapping sequence in between sigma0, core and component,
like the following: 0xe1000000 => 0xbf001000 => 0x10b000,
with the consequence that the component stalls when accessing
the latter one. By requesting I/O memory aligned to the size,
the faulty behaviour vanishes.
