- add a new function 'binary_ready_hook_for_gdb()' in ldso. GDB can set a
breakpoint at this function to know when ldso has loaded the binary
into memory.
- get the thread state from the NOVA kernel immediately on 'pause()'
Fixes#1968
Use kernel branch which is more accurate in accounting memory, which avoids
kernel messages of following form:
[0] warning: insufficient resources ...
Fixes#1830
Too less memory quota for a PD may be calculated, which leads to too early
punishment for a Genode process.
Discovered during Turmvilla scenario #1552 and issue #1733.
- free up kernel memory of empty slabs (if already one empty slab is in
place)
- free up more page table entries
- handle CPUs with invariant TSCs gracefully
Genode/Nova running on CPUs without the invariant TSC feature may seem
to 'hang'. The referenced commit of the nova branch fixes the issue
for some older Intel CPUs.
Fixes#1615
Avoids the need to have per IRQ a thread that blocks synchronously for next
interrupt. Now a thread may wait for multiple IRQs as other signals
simultaneously.
In core no threads are required anymore for IRQs/MSI - the clients (either
the pci_drv or in case of MSI the driver) gets the IRQ delivered directly as
a ordinary Genode signal.
Useful since #1216 and #1487 is now available.
Commit applies feature of #1446 also to IRQ/MSIs.
If running multiple VBox VMMs with Windows as guest concurrently then it may
happen that the system seem to hang. It turned out that actually
a VM-exit storm (vmx_exception->handle_exc_nm) causes a endless loop between
kernel and vCPU. Nothing gets scheduled nor interrupts are received anymore.
The referenced kernel commit fixes this issue.
Issue #1343
The commit uses a fixed kernel branch (r8), which fixes a caching bug
observable in the Genode host. The quirk detecting the circumstance in the
timer service is obsolete now and is removed.
Fixes#1338
