For pbxa9, Qemu is started with only 256 MiB for foc but with 768 MiB
for base-hw. By reducing the RAM quota for all start nodes within the
remote scenario, each component gets enough RAM quota to breathe.
When wrongly invoking the run script by specifying a skipped test
as its only TEST_PKGS argument, the run script fails due to a wrong
tar argument order. Let's better reflect this condition to the user
ahead of invoking tar.
With `MAP_FIXED` absent from the mmap(3p) flags, "the implementation uses
addr in an implementation-defined manner to arrive at pa", which may
lead to a mapping at an address diffent to the requested `addr`.
Add `MAP_FIXED` to the mmmap flags to force mapping to the specified
address.

Such messages can occur by chance when killing 'echo' while the program
blocks in an IPC call. It gets killed nevertheless. So the message does
not hint at a failure of the test.
In the context of #5138, the timer drivers for NOVA and base-hw had been
changed to support timeouts at a precision of 250 us (from formerly 1 ms).
Adjust the test to the new expected lower bound.
The dynamic buffer allocation increases the RAM demand slightly beyond
1M on seL4. Use 2M, as is already the default in pkg/terminal_crosslink.
Issue #5135
Replace the USB session API by one that provides a devices ROM only,
which contains information about all USB devices available for this client,
as well as methods to acquire and release a single device.
The acquisition of an USB device returns the capability to a device session
that includes a packet stream buffer to communicate control transfers
in between the client and the USB host controller driver. Moreover,
additional methods to acquire and release an USB interface can be used.
The acquisition of an USB interface returns the capability to an interface
session that includes a packet stream buffer to communicate either
bulk, interrupt, or isochronous transfers in between the client and the
USB host controller driver.
This commit implements the API changes in behalf of the Genode C API's
USB server and client side. Addtionally, it provides Usb::Device,
Usb::Interface, and Usb::Endpoint utilities that can be used by native
C++ clients to use the new API and hide the sophisticated packet stream API.
The adaptations necessary target the following areas:
* lx_emul layer for USB host and client side
* Linux USB host controller driver port for PC
* Linux USB client ports: usb_hid_drv and usb_net_drv, additionally
reduce the Linux tasks used inside these drivers
* Native usb_block_drv
* black_hole component
* Port of libusb, including smartcard and usb_webcam driver depending on it
* Port of Qemu XHCI model library, including vbox5 & vbox6 depending on it
* Adapt all run-scripts and drivers_interactive recipes to work
with the new policy rules of the USB host controller driver

Issue genodelabs/goa#81.
The kernel timer used to truncated timeouts to the next lower
millisecond, which not only limits the wakeup accuracy but also results
in situations where a user-level timeout is triggered earlier than
expected. The latter effect results in the observation of a spurious
timeouts and the subsequent programming of another timeout.
The patch solves the problem by preserving the sub-milliseconds bits
in the 'us_to_ticks' implementation(s).
Issue #5142
This patch modifies the mixer's time window allocation by modelling the
drift of the period length over time. This yields a much better
stability of the detected sample rates in the presence of jitter.
Issue #5132
This patch caps the busyness of the rump kernel, which normally calls
sleep with timeouts between 0 and 10 ms even when idle. On Sculpt
running on a x250 laptop, this patch saves 0.4% CPU load, which is
almost the half of the idle load.
Issue #5140
This data structure uses an AVL tree to maintain a time-sorted set of
alarm objects. It supports the use of circular clocks of an bit width.

The format library is required, otherwise the binary isn't build. This
regression was introduced in

The package depends on two resources.
- A Nic session should be routed to the nic_router "http" domain make
the HTTP server available from the outside on forwarded port 80.
- A File_system session labeled "webroot" can be routed to any server
by relabeling the session, e.g., to "report" or "config" in parent.
Sculpt deploy exmaple exporting report_fs via HTTP.
<start name="lighttpd" pkg="lighttpd">

<service name="Nic">
<child name="nic_router" label="http"/>
</service>
<service name="File_system" label="webroot">
<parent label="report"/>

Newer Qemu variants quit with an error about already existing devices
if the same device-id is add and removed in a loop fast. To circumvent
this strange behaviour, simply use consecutive device id numbers.

This patch was back ported from upstream Mesa and generalizes the memory
management of buffer objects used by the binder. Before this patch the
binder was treated as a special case where buffer objects were allocated
with a simple "next block or wrap" allocator. With this commit the
binder now uses the vm_heap allocators as done by all other buffer
allocations which leads to issues with reference counting and object
destruction being resolved.
Original commit message:
We're moving towards a path where all contexts share the same virtual
memory - because this will make implementing vm_bind much easier - ,
and to achieve that we need to rework the binder memzone. As it is,
different contexts will choose overlapping addresses. So in this patch
we adjust the Binder to be 1GB - per Ken's suggestion - and use a real
vma_heap for it. As a bonus the code gets simpler since it just reuses
the same pattern we already have for the other memzones.
This patch contains the mobile variant of Sculpt OS, which evolved
at the genode-allwinner repository until now. In consists of the
following parts:
- gems/src/app/phone_manager plays the role of the sculpt manager
- sculpt/phone-linux allows for test driving the mobile
variant on base-linux
- gems/src/app/dummy_modem mockup of a modem's behavior, used for
GUI development and testing
The parts targeting a specific device (PinePhone) remain local to
the genode-allwinner repository.
To give it a try:
make run/sculpt_test KERNEL=linux BOARD=linux \
SCULPT=phone LOG=core DEPOT=tar

- re-start block job scheduling on resume
