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.
Issue #5138
The format library is required, otherwise the binary isn't build. This
regression was introduced in
acpica: provide verbose config (issue #5083)
Fixes genodelabs#5136
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">
<route>
<service name="Nic">
<child name="nic_router" label="http"/>
</service>
<service name="File_system" label="webroot">
<parent label="report"/>
</service>
</route>
</start>
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:

Issue #5101
This commit is a preparation commit for suspend/resume. The commit
refactors the code in order to consolidate all Platform resources into one
instance. All users within the driver should access the resources with
with_* functions, which checks whether the device resource is usable. The
callers are not allowed to store any references to the provided resources.

Fixes#5081
This commit replaces the mapping of DMA buffers and gets rid of the
bounce-buffer handling, which was introduced to prevent data
corruption noticed when utilizing USB storage with Windows 10 guests,
with accessing the buffers directly.
Due to the way Windows 10 at times manages its DMA memory (many small
pieces instead of few larger ones) the unbounded registry becomes a
problem when containing stale entries.
Changing the 'qemu-usb' implementation allows for using 'read_dma'
and 'write_dma' directly.
Fixes#5121.
This patch enhances the audio driver with the option to operate as a
client of the record and play services instead of providing the audio-in
and audio-out services. The record/play mode can be enabled by setting
the 'record_play="yes"' config attribute.
The audio_in.run and audio_out.run scripts support the selection of the
mode via the 'use_record_play_sessions' hook function.

A read with MSG_PEEK returns -1 and EGAIN/EWOULDBLOCK in case the socket
is connected. Zero is only returned if the socket is disconnected.
isuee #5104
In case the socket is non-blocking, a read with the MSG_PEEK flag set
has to return -1 and EWOULDBLOCK/EAGAIN in case no data is availble and
the socket is connected. Returning zero implies the socket is in
non-connected state. Therefore, check the connection state in this
situation and return accordingly.
issue #5104
With the following changes, the hypervisor binary from bin/ as well as
from depot archives is taken as is and not unnecessarily turned inside
out.
- Remove objcopy -O elf32-i386 as our grub boots 64-bit binaries
very well
- Remove strip as bin/hypervisor is already stripped
- New session interfaces:
- os/include/play_session (for audio playing / mic-input driver)
- os/include/record_session (for audio recording / audio-output driver)
- Mixer at os/src/record_play_mixer providing both play and record services
- Simple waveform player at os/src/app/waveform_player
- Simple audio-signal capturing component at os/src/app/record_rom
- Simple oscilloscpe at gems/src/app/rom_osci (using record_rom)
- Simple test-audio_play for playing raw stereo f32 data
The _gems/run/waveform_player.run_ script illustrates the use of the new
components and interfaces.
