The mutex class is more restrictive in usage compared to
Genode::Lock.
- At initialiation time it is ever unlocked.
- No thread is permitted to lock twice. Warn about it
in case it happens.
- Only the lock onwer is permitted to unlock the mutex.
Warn about it and don't unlock the mutex in case it happens.
Issue #3612
Adding an explicit check clarifies at the first glance that the array
bounds are respected without needing knowledge about MAX_CAPS_PER_MSG
and L4_UTCB_GENERIC_DATA_SIZE (used for dimensioning 'mr').
Instead of hosting our outdated own fork, this commit now uses kernkonzept's
nowadays available github source repositories. This hopefully simplifies
updates, or cherry-picking single fixes.
Components like kernel, core, and bootstrap that are built for a
specific board need to reside inside the same architectural dependent
build directory. For instance there are sel4, foc, and hw kernel builds
for imx6q_sabrelite and imx7d_sabre, which have to reside inside the same
arm_v7 build directory.
This commit names those components explicitely, and adapts the run-tool to it.
Fix#3316
- kernel: propagate cr0 to VMM on exit in nested paging case
- kernel: disable forceful VM exit on task switch
- vm_session: adjust to kernel changes
Issue #3111
Track the dataspaces used by attach and add handling of flushing VM space
when dataspace gets destroyed (not triggered via the vm_session interface).
Issue #3111
* necessary for enabling the kernel debugging facilities on base-foc
(outstring, fiasco_tbuf_log_3val and friends)
* disabled by default

QEMU implements the cycle count register read by
'Genode::Trace::timestamp()', but does not report a supported debug model
version for Cortex-A9.
Fixes#3154
This patch adjusts the implementation of the base library and core such
that the code no longer relies on deprecated APIs except for very few
cases, mainly to keep those deprecated APIs in tact for now.
The most prominent changes are:
- Removing the use of base/printf.h
- Removing of the log backend for printf. The 'Console' with the
format-string parser is still there along with 'snprintf.h' because
the latter is still used at a few places, most prominently the
'Connection' classes.
- Removing the notion of a RAM session, which does not exist in
Genode anymore. Still the types were preserved (by typedefs to
PD session) to keep up compatibility. But this transition should
come to an end now.
- Slight rennovation of core's tracing service, e.g., the use of an
Attached_dataspace as the Argument_buffer.
- Reducing the reliance on global accessors like deprecated_env() or
core_env(). Still there is a longish way to go to eliminate all such
calls. A useful pattern (or at least a stop-gap solution) is to
pass the 'Env' to the individual compilation units via init functions.
- Avoiding the use of the old 'Child_policy::resolve_session_request'
interface that returned a 'Service' instead of a 'Route'.
