This repository is superseded by the 'dde_bsd' repository. Though
OSSv4 served us well, its future is uncertain and having active
upstream development is preferable. In addition the ported Intel
HD Audio driver did not work on any Thinpad model newer than T60.
Issue #1498.
These audio drivers enable support for Intel HD Audio (Azalia) and
Ensoniq AudioPCI (ES1370) compatible soundcards. They are ported
from OpenBSD 5.7.
Fixes#1498.
This is especially true for i.MX53 but is not needed on Arndale
currently.
@skalk the test will still fail each night as we do not have a nic_drv
for imx53...
- send a 'state_change' signal on session creation if the device is
already attached
- evaluate the status code of a finished asynchronous operation
- return the number of actually transferred bytes for control transfers,
too
Fixes#1490
This patch avoids the attempt to extend the cxx-local heap during the
startup phase of an application. Originally, the static part of the cxx
was merely 100 bytes, which did not suffice to run the minimalistic test
roottask on seL4.
Fiasco.OC limits the UTCB area for roottask to 16K. Therefore, the
number of threads is limited to 16K / L4_UTCB_OFFSET. (see
kernel/fiasco/src/kern/kernel_thread-std.cpp:94)
In the past, when the user blocked for an IRQ signal, the last signal was
acknowledged automatically thereby unmasking the IRQ. Now, the signal session
got a dedicated RPC for acknowledging IRQs and the HW back-end of that RPC
acknowledged the IRQ signal too. This led to the situation that IRQs were
unmasked twice. However, drivers expect an interrupt to be unmasked only on
the Irq_session::ack_irq and thus IRQ unmasking was moved from
Kernel::ack_signal to a dedicated kernel call.
Fixes#1493
White list access to ports we actually need for our drivers so far and
deny everything else by default. The extend pci config space dataspace is
currently not used and exposes a potential risk (BAR rewrite) - so deny.

If a null-terminated string exactly of length MAX (0 byte included) is
provided, it will be handled as invalid because of wrong string size length
checks.
Commit fixes this.
Discovered during #1486 development.
Step to move shared irq handling out of core in the long run. So, use
irq_proxy implementation from base in os and implement shared irq handling
in platform driver of x86 (pci_drv).
Fixes#1471
