- adjust syscall bindings to support -fPIC
- read serial i/o ports from BIOS data area
- use autoconf.h provided by sel4
-- to avoid ambiguity between sel4 kernel and user libraries
-- remove manual set defines
- remove debug messages
- increase user virtual area to 3GB

and show some message about. On sel4 sometimes exceptions are thrown and no
message is shown, it just seems to hang. With this patch at least you get
an idea that something bad happened.
Issue #2044
- remove special handling from base-nova
- add to rpc_server where it actually should be applied to
- required to work for sel4 cancel_blocking

Now, we support multi-touch devices generating multi-touch events and
absolute-pointer devices simultaneously with multitouch="yes". Still,
multitouch="no" generates emulated absolute-pointer events for
multi-touch devices.
Add option to load the initial overlay*.vdi from disk, but keep the changes
in a ram_fs.
Used with AHCI model for vbox_auto_win7. Currently we have no way to tell
rump_fs to unmount and write back data to disk before resetting the machine.
On MVM only the initial scanning of APs works. If wpa_supplicant changes
from triggered scans to the scheduled-scanning hardware feature no
further scan results are reported. Therefore, we disable the
scheduled-scanning hardware feature until the issue is fixed.
Issue #2046
When running the same kernel in a VM as on the host system and the
kernel boot message from the VM appears on the log output, the run tool
assumes that the host machine has rebooted unexpectedly. With this
commit, an unexpected reboot is assumed only if the kernel boot message
appears at the beginning of a line. On base-hw, we enforce a line feed
at the beginning of the boot message as the SPIKE emulator log starts
with the first message of the kernel lacking a line feed.
Fixes#2041
Thread stacks with less than 4K usable space are insufficient for our
implementation of Linux exception signal handling. If such a unusually
small stack overflows the SIGSEGV handler will not be able to print the
diagnostic message leaving no hint of the cause of the stuck process.
The linker scripts are known to reside in BASE_DIR. By using them
directly from this location instead of searching them in the
REPOSITORIES, we don't need to specify the repos/base as a repository in
order to link.
This patch handles x86_32 and x86_64 separately since this is the SPEC
value directly supplied to the package build tool. This way, we achieve
that a CROSS_DEV_PREFIX is defined for each supported argument.
This patch adds the methods 'sigh_ack_avail()' and
'sigh_ready_to_submit()', which are needed to build asynchronously
operating file-system clients.
Fixes#2023
Those headers implement a platform-specific mechanism. They are never
used by components directly.
This patch also cleans up a few other remaining platform-specific
artifact such as the Fiasco.OC-specific assert.h.
Issue #1993
Conveying the ROM filename as the final label element simplifies
routing policy and session construction.
Annotations by nfeske:
This commit also changes the ROM session to use base/log.h instead of
base/printf.h, which produced build error of VirtualBox because the
vbox headers have a '#define Log', which collides with the content of
base/log.h. Hence, this commit has to take precautions to resolve this
conflict.
The commit alse refines the previous session-label change by adding a
new 'Session_label::prefix' method and removing the use of 'char const *'
from this part of the API.
Fixes#1787
Session_label constructor now takes a bare string rather than a
serialized argument buffer.
Replace all instances of previous constructor with 'label_from_args'
function.
Issue #1787
This patch establishes the sole use of generic headers across all
kernels. The common 'native_capability.h' is based on the version of
base-sel4. All traditional L4 kernels and Linux use the same
implementation of the capability-lifetime management. On base-hw, NOVA,
Fiasco.OC, and seL4, custom implementations (based on their original
mechanisms) are used, with the potential to unify them further in the
future.
This change achieves binary compatibility of dynamically linked programs
across all kernels.
Furthermore, the patch introduces a Native_capability::print method,
which allows the easy output of the kernel-specific capability
representation using the base/log.h API.
