- remove Spike/BBL support in favour of Qemu (>=4.2.1)
- add 'riscv_qemu' board, remove 'spike' board'
- update to privileged ISA v1.10 (from v1.9.1)
- use direct system calls for privileged core threads (they call into
the kernel and don't use mode changing system calls, i.e. 'ecall',
semantics)
- use 'OpenSBI' semtantics for SBI calls (to machine mode) instead of
BBL
issue #4012
* Remove SPEC declarations from mk/spec
* Remove all board-specific REQUIRE declaratiions left
* Replace [have_spec <board>] run-script declarations with have_board where necessary
* Remove addition of BOARD variable to SPECS in toplevel Makefile
* Move board-specific directories in base-hw out of specs
Right now the same code dealing with nic setup on qemu is duplicated
in many different run scripts. It makes it unnecesarily complex to
change the existing config or add support for new nic types. Lets move
all this common code to qemu.inc.
Ref #3825
It seems Qemu 5.0.0 no longer supports gic_version parameter.
Apparently this only worked due to some compat feature that
was dropped in Qemu 5.0.0. The replacement which works on both
old and new Qemu versions is gic-version.
Fixes#3823
This patch adds support for booting base-hw kernel on qemu-arm virt
machines. The arm_virt machine has 2GB of RAM, 2 Cortex A15 cores and
uses GICv2 interrupt controller. The arm_64_virt machine also has 2GB of
RAM, but has 4 Cortex A53 cores and uses GICv3. Both machines use PSCI
to boot additional CPU cores.
Fixes#3673
The plugin was tested with ALL4176 but should support all modern Allnet
MSR devices according to the documentation
https://service.allnet.de/image-ftp/ftp/pub/allnet/MSR/JSON/JSON_MSR.zip
It works just like the existing powerplug plugins by
RUN_OPT += --include power_on/allnet --include power_off/allnet
and uses the following parameters
--power-on-allnet-host network address of device
--power-on-allnet-user user for device
--power-on-allnet-password password for device
--power-on-allnet-port target port/socket of device
--power-off-allnet-host network address of device
--power-off-allnet-user user for device
--power-off-allnet-password password for device
--power-off-allnet-port target port/socket of device
Also remove 'requires_installation_of', while also checking sbin
directories in 'have_installed'. The run scripts have been adjusted
accordingly.
Fixes#2853
Our static okl4 system-integration configuration specifies a fixed RAM
range from 32 to 800 MiB, which must be satisfied by Qemu or strange
errors happen due to accesses beyond RAM. (Fixes current issues with
nic_router.run.)
Switch port I/O based PCI config space access to memory-mapped IO. The
base address of the PCI configuration space is acquired by mapping the
ACPI ROM and reading the first <bdf> node. An exception is thrown if the
first <bdf> node is not for PCI domain zero or if multiple <bdf> nodes
exist. This is to reduce complexity and also because multiple PCI
domains are rare.
The PCI configuration space is accessed via I/O mem dataspace which is
created in the platform_drv root and then passed on to the PCI session,
device components and finally to the actual PCI config access instances.
The memory access code is implemented in a way to make it work with Muen
subject monitor (SM) device emulation and also general x86 targets. On
Muen, the simplified device emulation code (which works also for Linux)
always returns 0xffff in EAX to indicate a non-existing device.
Therefore, EAX is enforced in the assembly templates.
Fixes#2547
When building Genode on a Linux system running in a Xen Dom0, the 'xen'
run target can run a Genode scenario in a Xen DomU.
Usage: in build/x86_*/etc/build.conf, define:
RUN_OPT = --include boot_dir/$(KERNEL) --include image/iso --include power_on/xen --include log/xen --include power_off/xen
The Xen DomU runs in HVM mode and loads Genode from an ISO image. Serial
log output is printed to the console and graphical output is shown in an
SDL window.
The Xen DomU ist managed using the 'xl' command line tool and it is
possible to add configuration options in the 'xen_args' variable in a run
script. Common options are:
- disabling the graphical output:
append xen_args { sdl="0" }
- configuring a network device:
append xen_args { vif=\["model=e1000,mac=02:00:00:00:01:01,bridge=xenbr0"\] }
- configuring USB input devices:
append xen_args { usbdevice=\["mouse","keyboard"\] }
Note: the 'xl' tool requires super-user permissions and interactive
password input can be troublesome in combination with 'expect' and is not
practical for automatic tests. For this reason, the current implementation
assumes that no password input is needed when running 'sudo xl', which can
be achieved by creating a file '/etc/sudoers.d/xl' with the content
'user ALL=(root) NOPASSWD: /usr/sbin/xl'
(where 'user' is the Linux user name).
Fixes#2504
This commit mostly removes the globally visible NR_OF_CPUS define
from the global makefile specifiers defined in the base-hw repository.
Whereever necessary it adds platform specific makefiles to the base
repository when they were missing.
Ref #2190
Instead of holding SPEC-variable dependent files and directories inline
within the repository structure, move them into 'spec' subdirectories
at the corresponding levels, e.g.:
repos/base/include/spec
repos/base/mk/spec
repos/base/lib/mk/spec
repos/base/src/core/spec
...
Moreover, this commit removes the 'platform' directories. That term was
used in an overloaded sense. All SPEC-relative 'platform' directories are
now named 'spec'. Other files, like for instance those related to the
kernel/architecture specific startup library, where moved from 'platform'
directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.
Fix#1673
The plugin works just like the netio plugin and uses the following
parameters
--power-off-energenie-host network address of device
--power-off-energenie-password password for device
--power-off-energenie-port target port of device
The run plugin is not generic and works for NETIO4/NETIO230 powerplugs
only. Further, this opens the path for other vendor-specific powerplug
plugins.
Note, the plugin parameter for the addressed powerplug was renamed to
--power-on-netio-host resp.
--power-off-netio-host
The base-hw kernel on x86_64 currently assumes 254 MiB of RAM. The RAM
region is subtracted from the I/O mem allocator and therefore this range
is not available for device I/O.
If qemu is started with -m 128, the region for (emulated) PCI config
space access lies within this region and I/O mem allocation in the
pci_drv will fail. Giving qemu more RAM moves the PCI config space out
of the 254 MiB region, making the run/libc_ffat scenario with acpi work.
