* 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.

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.
Ref genodelabs/genode#5115
Give certain scheduler class wide variables and functions clear names:
* quota => super_period_length
* residual => super_period_left
Ref genodelabs/genode#5115
Replace double linked list by normal Genode::List with an additional
pointer to last list member to efficiently handle the scheduler share lists.
Moreover, move it into the private part of the Cpu_scheduler class,
the only scope where it is used anymore.
Ref genodelabs/genode#5115
Minor changes that should not change any semantics:
* Remove `_next_fill()` its short and only used in one context,
in which it is good to know what that code actually does
* Turn boolean values into actual boolean values
* Remove some brackets around one-liner pathes
Ref genodelabs/genode#5115
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.

Check if controllers port count matches number of ports found in the
port implemented register. In case counts don't match print a diagnostic
message for debugging purposes.
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
coordinates by a sequence of translation (move), scaling, rotation, and flipping
primitives in sub-nodes.
Issue #5105
Per default, only key presses and releases are logged. The optional
'motion' attribute (boolean) enables logging of motion and touch events.
Issue #5105
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 IP for the connect timeout test should be in another nic_router
domain, so ARP request are only processed be the nic_router and no other
IP stacks.
issue #5104
Adjust the plugin to use the socket C-API found under
dde_linux/src/lib/lxip/include/genode_c_api/socket.h'.
This is the first minor step in generalizing the plugin.
isse #5104
The lxip_raw.run script will spawn a client/server scenario that tests
Genode C-API calls. The scenario can be used standalone, meaning no
actual network card is required.
issue #5104
This commit updates lxip from version 4.4.3 to 6.1.20. It uses the
current lx_kit approach and is a shared library again. The stack has
been tested for x86_32/x86_64/arm_v6/arm_v7/arm_8.
The C-interface of the IP stack can be found under
lxip/include/genode_c_api/socket.h.
issue #5104
CONFIG_X86_USE_PPRO_CHECKSUM is a 'def_bool y' and gets re-enabled by
'make olddefconfig'. The PPRO version contains text relocations which we cannot
have in binaries (e.g., 'lea 45f(%ebx ...).').
