Previously for determining wether boot-up succeeded or not, we looked
for a message that is switched off in release mode. Now the kernel
provides a reliable message as soon as initialization is done.
ref #1096
In this case "mv A B" works slightly different than "cp A B; rm A" as
symbolic links come into play. The statements should copy the contents
of A into the symboliv link at B (preserving it as is) and remove A. The
mv would replace the link B by the binary A.
Fixes#805.
If the target machine is connected locally one may specify
"serial" as target in the RUN_OPT variable to get the test output.
Used for panda and arndale on foc and hw.
Use RUN_OPT="--target ..." to select the backend test method.
Supported values so far:
qemu - qemu + grub bootloader (default)
qemu+pxe - qemu + pulsar bootloader (PXE)
amt - Intel AMT (reset+serial output) + pulsar bootloader
Related to issue #598
genode_until_run can be called now with a spawn id to able to reattach to a
spawned process (amt, serial output). Run scripts can now call genode_until_run
multiple times.
Implies support for the ARMv6 architecture through 'base-hw'.
Get rid of 'base/include/drivers' expect of 'base/include/drivers/uart'.
Merge with the support for trustzone on VEA9X4 that came from
Stefan Kalkowski.
Leave board drivers in 'base/include/platform'.
Rework structure of the other drivers that were moved to
'base_hw/src/core' and those that came with the trustzone support.
Beautify further stuff in 'base_hw'.
Test 'nested_init' with 'hw_imx31' (hardware) and 'hw_panda_a2' (hardware),
'demo' and 'signal' with 'hw_pbxa9' (qemu) and 'hw_vea9x4'
(hardware, no trustzone), and 'vmm' with 'hw_vea9x4'
(hardware, with trustzone).
* Introduces Schedule_context
* Use fast-interrupts or normal interrupts
* Add mode-transition between secure/non-secure world
* Limit system resources for Genode apps due to non-secure world
This commit implements the newly introduced Vm session interface to be used
on top of TrustZone capable Armv7 CPUs. Therefore a new Schedule_context is
introduced in the kernel. Threads and Vms are both Schedule_contexts used
by the scheduler. In contrast to a thread a vm uses a different assembler
mode switch to the non-secure, virtual world, as well as another exception
is used, when the non-secure world is left. For both worlds to co-exist
the interrupt-controller needs to be configured, so that the secure (Genode)
world uses fast-interrupts only, and the non-secure world only legacy
interrupts.
The only TrustZone capable platform the base-hw kernel works on top of
is the CoreTile Express 9x4 for the Versatile Express motherboard. For a
virtual machine working properly on top some platform resources must be
reserved. Therefore there exist two flavours of this platform now, one with
the 'trustzone' spec-variable enabled, and one without. If 'trustzone' is
specified most platform resources (DDR-RAM, and most IRQs) are reserved
for the Vm and not available to the secure Genode world.
