Under certain timing conditions, the test would end up flushing the
input from the input filter in a nested way, which ultimately resulted
in lost input events of the outer nesting level. This patch eliminates
this corner case and thereby stabilizes the key-repeat test.
Transfer quota to the session local RAM session to react to the
Quota_exceeded exception properly.
The platform driver keeps a session local RAM session for each of its
clients that is used to allocate DMA memory. A client needs to transfer
some of its quota to the platform driver, which in return transfers this
quota to the session local RAM session. As it happens allocating memory
from a RAM session involves book keeping and in this case, where the
available quota in the session did not suffice and the request was only
a few KiB, the platform driver handled the exception wrongly and did not
transfer the quota.
This problem did not surface up to now because all drivers allocate DMA
memory in larger chunks and the book keeping overhead was of no
consequence as the initial quota transfer probably covered the overhead.
Fixes#2316.
This enables to use append_if like the append command in the following
situation.
proc optional_binary {} {...}
append_if $optional config {
<start name="} [optional_binary] {">
...
}
Due to rounding in the timeout calculation it may happen that the timeout
stored in ms becomes 0, but actually some time (us or ns) are left to wait.
With threads on various priorities (vbox) this may end up in endless loops.
Fixes#2311
The file space demand for the object files when compiling core has grown.
Therefore, the ram_fs component runs out of memory and requests additional
memory from init. On OKL4, where the physical memory is limited by the
elfweaver bootstrap tool, there is no more slack memory after the donation
of 1G to noux.
* Increase test-thread count to trigger quota exceeding on all platforms
* Synchronize test-thread destruction, otherwise an half-destructed thread
object can lead to an error message of the thread to be destructed,
which causes a deadlock, when the destructed thread still holds the log lock
* Limit SMP settings for QEMU to x86 (Ref #2307)
The signal_1/2/3 objects (which are threads) are in destruction, but still
signals are send to them. When the signal arrive and the memory for the
signal_1/2/3 object is already invalid we operate on stale memory and all
the locking infrastructure of the Thread don't work anymore.
Be more robust, explicitly wait for the termination of the thread.

Otherwise it may happend that the Guest tries to set the last stored
resolution from another run, which maybe is too large.
Up to now, everthing is fine, beside the fact that output changes are not
visible - which is odd and one things the VM came not up.
Issue #2306
that happened during early bootup.
The signal about input events may arrive before keyboard and mouse is set
(due wait_and_dispatch_one_signal called from a started pthread and ep still
not done with the initialisation)
Issue #2306
Previously we had configured the timer for the Panda ES with 700 MHz
CPU clock. But the Panda A6 that we use as reference now runs with
800 MHz.
Fixes#2308
Previously, on X86, the timer driver used the PIT with a maximum timeout
of 54 ms. Thus, the driver frequently interrupted the counters with
highest priority to update the timer. This is why we needed a higher
error tolerance as for ARM where the driver, once configured, can sleep
for the whole test timeout. Now, we use the kernel timer and the problem
seems to be exits no longer.
Ref #2304
Previously we pre-calculated the translation errors for the session
quota to make a discret check in the test. But since the order, in which
init childs get their CPU quota isn't always the same anymore (we should
have never made assumptions about that) the translation errors differ
from trial to trial. However, the errors are below 0.01% of the super
period. We now tolerate them in the run script.
Ref #2304
We call curl a second time if the first check fails. This gives download
sites time to reconsider their response and helps, for example, to check
the qemu-usb port.
By separating the plain MMIO access implementation from the generic bit
and offset logic of registers, we can now use the latter also with other
types of register access like I2C. The register and MMIO front-ends have
not changed due to the separation.
