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.

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.

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.

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.

- 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.

* Move Kernel::Cpu_scheduler to Kernel::Scheduler
(we only have that one scheduler)
* Move Kernel::Cpu_share to Kernel::Scheduler::Context
* Move Kernel::Cpu_priority to Kernel::Scheduler::Priority
* Rename all functions and variables refereing to `claims` to
`prioritzed`, because claims is not that common
* Rename occurrences of `fill(s)` to `slack` to name the time portions
outside of the prioritized quantum
* Get rid of some two-liner sub-functions with only one occurrence
(like `_quota_introduction`, `_quota_revokation`,...)

This private, internal function is used only in one scope,
and therefore not neccessary. But it has nasty side-effects as
it takes the parameter `duration` as reference and changes its
value. Just remove it completely.
Ref genodelabs/genode#5115
The name head is already extensively used in the context of the lists
managed by the scheduler. This terminology duplications does not simplify
reading the code. Instead we keep head for the first item in the list,
but use `current` in the variable name and API of the `Cpu_scheduler`
class to refer to the current scheduled share.
Moreover, the `_head_quota` is now `_current_time_left`, because it does
not denote quota but time left for the current schedule. The boolean
variable `_head_claims` gets removed at all. It duplicated the state of
whether a current share ist set, and whether it has so-called claim time
left.

Minor changes that should not change any semantics:
* Remove `_next_fill()` its short and only used in one context,

The `_head_was_removed` variable got introduced in solving #4710, but it
reflects only whether `_head` is a valid pointer or not, thereby it
duplicates state.

issue #4081
The key element of the improvement is differentiated processing of
events of the following device types.
Mouse: relative motion
Pointer: absolute motion (Qemu usb-tablet and IP-KVM devices)
Touchpad: relative motion via absolute touchpad coordinates
Touchtool: absolute motion (e.g., stylus)
Touchscreen: absolute motion and finger (multi-) touch
Processing is done in two stages for one "input packet". First, all
events of the packet are recorded into the current evdev state with
device-type specific operations. Then, appropriate Genode input events
are generated from the accumulated evdev state in the submission stage
(again by device-type specific functions).
A simple version of tap-to-click was added to the touchpad support.
Fixes#5105
The <transform> filter configurably transforms touch and absolute-motion event

This commit enables generic Linux multi-touch support as well as support
for the Wacom Intuos/Graphire tablets as found in the previous version
of the USB HID driver. Events are not properly propagated through
Genode's Event C-API, yet, which will be a follow up.
Issue #5105
When SMP is enabled multicore specific instructions (e.g., pldw) are
generated. These are not supported and lead to invalid instruction
faults on uni-processor systems (like Cortex-A8). Therefore, we disable
SMP for arm_v7 in Linux code. This requires also a switch from the RCU
tree implementation to RCU tiny, which we shadow and dummy implemented.
issue #5104
Until now, in case 'jent_entropy_init' failed an error has been produced
and the following jitterentropy functions (i.e.,
'jent_entropy_collector_alloc') where called nevertheless. In case we
received a bad time source error, for example because the performance
counters are not working on the platform, the entropy collector did not return (endless
loop).
Therefore, this commit treats the failed jitterentropy initialization
not as an error but prints a warning about poor randomness quality and
stops using the jitterentropy library from this point on. The
'Jitterentropy::gen_random_u64' will in this case return the address of
a stack variable * some counter.
This is only a interim solution to make platforms work where performance
counters or TSC values do not exist/work.

issue #5104
The classes Genode::Mmio, Genode::Register_set, Genode::Attached_mmio, and
Platform::Device::Mmio now receive a template parameter 'size_t SIZE'. In each
type that derives from one of these classes, it is now statically checked that
the range of each Genode::Register::Register- and
Genode::Register_set::Register_array-deriving sub-type is within [0..SIZE).
That said, SIZE is the minimum size of the memory region provided to the above
mentioned Mmio classes in order to avoid page faults or memory corruption when
accessing the registers and register arrays declared inside.
Note, that the range end of a register array is not the end of the last item
but the end of integer access that is used for accessing the last bit in the
last item.
The constructors of Genode::Mmio, Genode::Attached_mmio, and
Platform::Device::Mmio now receive an argument 'Byte_range_ptr range' that is
expected to be the range of the backing memory region. In each type that derives
from on of these classes, it is now dynamically checked that 'range.num_bytes
>= SIZE', thereby implementing the above mention protection against page faults
and memory corruption.
The rest of the commit adapts the code throughout the Genode Labs repositories
regarding the changes. Note that for that code inside Core, the commits mostly
uses a simplified approach by constructing MMIO objects with range
[base..base+SIZE) and not with a mapping- or specification-related range size.
This should be fixed in the future.
Furthermore, there are types that derive from an MMIO class but don't declare
any registers or register arrays (especially with Platform::Device::Mmio). In
this case SIZE is set to 0. This way, the parameters must be actively corrected
by someone who later wants to add registers or register arrays, plus the places
can be easily found by grep'ing for Mmio<0>.

Issue #4081
Hitting a BOSD in a Windows guest in Virtualbox 6 leads to calling
`DBGFR3ReportBugCheck`, which leads to the following error since it is
unimplemented in our port:
```
Error: DBGFR3ReportBugCheck: DBGFR3ReportBugCheck called, not implemented, eip=0x1a5c4e4
```
Including the actual method from Virtualbox 6 enables logging
diagnostics for the Windows Blue Screen of Death (BSOD).
To see Blue Screen logging output, enable "dbgf" and "gim" logging
via the `VBOX_LOG` following environment variable in the vbox6 runtime
config.
When manually triggering a BSOD in the Windows guest, this should
produce the following logging diagnostics:
```
GIM: HyperV: Guest indicates a fatal condition! P0=0xe2 P1=0x0 P2=0x0 P3=0x0 P4=0x0
GIMHv: BugCheck e2 {0, 0, 0, 0}

The libc's internal calculation of the tv_sec and tv_nsec fields must be

incremented whenever tv_nsec wraps. For applications, this inconsistency
can result in observed jumps in time.
Fixes#5098
Functions registered with 'module_init' (i.e., '__define_initcalls'),
'OF_DECLARE', and 'DECLARE_PCI_FIXUP_CLASS_FINAL' used to be static
constructors and had be explicitly registered using
'exec_static_constructors' before executing any Linux code.
With this commit we remove the constructor attributes from these
functions and create a global function pointer in the form of
__initptr_<name>_<id>_<counter>_<line number of macro>
'import-lx_emul_common.inc' will collect these '__initptr' symbols after
the compile step and generate a 'lx_emul_register_initcalls' function
that executes the functions pointed to. This step is now automatically
performed in 'lx_emul_start_kernel'. This way a call to
'exec_static_constructors' can be omitted in case there are no other
constructors in place.

The former implementation relied on input drvdata always pointing to

states.
This commit brings the etnaviv back end implementation in line
