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 a pkg is missing, the user should create <arch>/pkg instead
of only the missing pkg. This way, all depending binaries are created in
one step. Otherwise the missing binaries are detected at the next time
the run script is executed. This patch relieves the user from iterating
manually.
This commit changes the semantic of run_boot_dir to link a core
binary with debug symbols only when the designated library is in place.
Follow-up fix refering to issues #2339 and #2700
The install_pxe_bootloader_to_run_dir procedure is required by the tftp
as well as the ipxe load script. Move it to a separate file which is
include by both.
- Use latest Muen version
- Sync VirtualBox Muen subject state
- Drop unneccessary subject IP patch
- Adapt Muen RUN_OPTs
- Update documentation
Note: the GPL 2017 toolchain is now required and as the debug output
format has changed the mulog-subject.py script must be updated on
autopilot instances.
The timestamp-based rules of make do not work well for the publish tool
because depot archives are often re-created with the same content but a
different modification time, in particular when creating archives via
'FORCE'. This way, those archives are re-published every time, which
becomes a time-consuming operation since all archives must be signed.
This patch filters the targets based on the content that is already
present in the public/ location. All existing archives are skipped.
Apply the approach to join the argument list 'args' to pass a single
list argument to _collect_from_depot. Actually, this story teaches me to
shy away from {*} because of its special semantics, which are
{*} makes each item in a list an individual argument of the current
command (https://wiki.tcl.tk/17158)
This is a direct follow up to "run: let import_from_depot accept list
variables", which broke calling import_from_depot with a number of
individual arguments.
Issue #2619
When doing something like this in a run script ...
lappend arg X
lappend arg Y
lappend arg Z
import_from_depot arg
... the internals of import_from_depot do not treat $arg as list but as one
string and interprets it as malformed depot path. We can handle this by
applying {*} to $arg inside the procedure.
Issue #2619
This patch changes the depot layout such that each archive is
represented as a directory that contains the versions of the archive as
subdirectories.
Issue #2610
The run tool now by default checks configurations with target-specific
XML schemata. Each component may define a config schema file in its
target.mk via the CONFIG_XSD variable. When the run tool has checked an
configuration of an init instance, it additionally goes through the
start nodes of the config. For each start node it checks whether there
is an XSD file that matches. If so, the run tool also checks the config
of the start node (if existant). This is done recursively. I.e., also
the child configs of a sub-init of a sub-init of the top-level init
receive a config check.
Issue #2600
In general, make the message conform to the according message of the
common build system. Adds instruction how to fix the missing/outdated
port.
Fixes#2573
If there is no debug/core-<kernel>.o library available, e.g., when
running a scenario in a fresh build directory where core is provided
via a depot package, the build_core_image step of the run tool was
canceled in the past, when trying to access the non-existing library.
This commit changes the semantic of build_core_image to link a core
binary with debug symbols only when the designated library is in place.
This fixup is related to issue #2339
* introduce new syscall (core-only) to create privileged threads
* take the privilege level of the thread into account
when doing a context switch
* map kernel segment as accessable for privileged code only
Ref #2091
* introduces central memory map for core/kernel
* on 32-bit platforms the kernel/core starts at 0x80000000
* on 64-bit platforms the kernel/core starts at 0xffffffc000000000
* mark kernel/core mappings as global ones (tagged TLB)
* move the exception vector to begin of core's binary,
thereby bootstrap knows from where to map it appropriately
* do not map boot modules into core anymore
* constrain core's virtual heap memory area
* differentiate in between user's and core's main thread's UTCB,
which now resides inside the kernel segment
Ref #2091
In the image.elf file, the very last boot module is followed
by arbitrary other core-local data. Since those boot modules are
exported as page-granular dataspace to the outside of core via core's
ROM service, we need to ensure that the last page is padded with zeros.
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 patch enables one to supply a list of arguments to
'install_config'. The arguments appear concatenated in the resulting
config file. This is useful for embedding dynamically generated content
into an otherwise static configuration. For example, in the following
config, the 'pkg' attribute of the '<query>' config node is defined by
the return value of the 'query_pkg' function:
install_config {
<config>
...
<start name="depot_query">
...
<config>
<query pkg="genodelabs/pkg/} [query_pkg] {"/>
</config>
</start>
</config>}
- Update FatFS port from 0.07e to 0.13
- Multi-device support
- Basic test at run/fatfs
- Adaption of existing components
Note, ffat is now consistently renamed to fatfs.
Ref #2410
relocation is required, to avoid overlapping phdr in the elf binaries, but
sel4 will fail to boot if bender relocates the images at the end of physical
memory. Limit the physical relocation address to a fixed 256M value, so that
sel4 will work.
Issue #2451
The new version of the test exercises the combination of fs_report with
ram_fs and fs_rom as a more flexible alternative to report_rom.
It covers two corner cases that remained unaddressed by fs_rom and
ram_fs so far: First, the late installation of a ROM-update signal
handler at fs_rom right before the content of the file is modified.
Second, the case where the requested file is not present on the file
system at the creation time of the ROM session. Here, the ram_fs missed
to inform listeners for the compound directory about the later created
file.
The former use of 'arm_v7' as architecture was too unspecific. Depot
binary archives for Cortex-A8/A9 platforms should be generated for
the 'arm_v7a' architecture to define the required compile flags
(i.e., -march).
When building with multiple jobs, the 'Makefile' rule may be executed
before any of its sibling rules, which implicitly create the target
directory. In this case, the attempt to create the symlink for
'Makefile' fails and the 'build_bin_archive' aborts. Analogously to the
sibling rules, this fix creates the target directory as a side effect of
the 'Makefile' rule.
This patch makes the build step of the create tool conditional. If
merely creating api, src, pkg, or raw archives, the invocation of the
'build' tool can be skipped. Otherwise, the heap message for the 'build'
tool is displayed (because it is called w/o any arguments), which is
misleading to the user.
The depot tool did not consistently distinct libraries from regular
targets when handling binary archives. The binary archive of a regular
target is located at <user>/<bin>/<arch>/<name> whereas a library is
located at <user>/<bin>/<arch>/<api>/<name>.
Fixes#2438
This patch replaces the toy downloader (that merely copied files
locally, for testing) with the mechanics needed to download files from a
www server.
It also changes the use of GPG to use detached signatures.
Issue #2339
We do not have debug symbols in the bin/ binaries anymore. Thus, use the
debug/ binaries instead. We now have kernel specific binary names for
ld.lib.so and some others. Adapt, to this fact as well. For doing so
without unnecessary output, provide a new parameter "silent" at the
"kernel_specific_binary" procedure.
Ref #2398
Removes the following Fiasco.OC specific features:
* GDB extensions for Fiasco.OC
* i.MX53 support for Fiasco.OC
* Kernel debugger terminal driver
* Obsolete interface Native_pd
* Obsolete function of interface Native_cpu
Previously, the debugging version of the core image
(<build_dir>/var/run/<run_name>.core) was created by the run tool from
the common core object file
(<build_dir>/var/run/<run_name>/core-<kernel>.o). This object file,
however, was already stripped by the build system and thus didn't
contain debug info anymore. The build system also creates an unstripped
version in <build_dir>/debug/core-<kernel>.o, so we now use this one
for <build_dir>/var/run/<run_name>.core.
Ref #2254
This way, files copied from the depot are incorporated in addition to
the files explicitly specified as boot modules.
The patch also adds an automatic check for the validity of the XML
syntax of boot modules ending with '.config'.
Issue #2339
Run scripts can use the new 'import_from_depot' function to incorporate
archive content from the depot into a scenario. The function must be
called after the 'create_boot_directory' function and takes any number
of pkg, src, or raw archives as arguments. An archive is specified as
depot-relative path of the form <user>/<type>/name. Run scripts may
call 'import_from_depot' repeatedly.
An argument can refer to a specific version of an archive or just the
version-less archive name. In the latter case, the current version (as
defined by a corresponding archive recipe in the source tree) is used.
If a 'src' archive is specified, the run tool integrates the content of
the corrsponding binary archive into the scenario. The binary archives
are selected according the spec values as defined for the build directory.
As of now, only x86_32 and x86_64 are supported by the 'depot_spec'
function.
