Prior to this change the libdrm Lima implementation supported the
creation of multiple contexts where each context, however, was
treated as the same client like it was done in the Lima driver
itself.
With this commit each context becomes its own client while the
main context always performs all buffer object related allocation
and the other context import each needed BO before submitting.
Fixes#4760.
Sync file-descriptors a purely virtual and are not known by the libc and
should be only accessed by 'drm_poll'. To prevent accidental access move
them to range never used by the libc fd allocator.
Issue #4760.
We determine the owner of a Vram object by the session cap of the
session that created the object. We should not copy this cap to other
places because this increases reference counting, that can become very
large with many objects. Therefore, we pass a wrapper 'Owner' object
containing the cap by reference.

* 'map_buffer', GTT mappings are currently not used by Iris
* 'set_tiling', tiling is currently not used by Iris because there are
no GTT mappings
issue #4713
Change the abstraction from buffers to video RAM (VRAM). The notion of
buffers can be provided at the client side (e.g., Mesa) and multiple
buffers can be there be associated to one VRAM area, thus saving
resources (meta data overhead) when allocating many buffers. A VRAM area
can also be mapped to one single buffer as before for clients or drivers
that do not take advantage of this feature.
issue #4713
by checking for it in core, submitting a signal (if registered) and not
replying instantly. Before this commit, an exception (a non page fault)
caused and endless "unknown exception" loop between originator and core.
This was handled before commit "core: kernel-agnostic 'Mapping' type" by
throwing an exception, which was with that commit not working anymore.
Fixes#4751
Segment assignment stays valid for all sections following .dynamic,
which implies that .got and co also end up in the PT_DYNAMIC segment.
This is not intended. Therefore, we move the .dynamic section before
bss and assign bss to the rw PT_LOAD segment only.
fixes#4750
By default, bender will not report any serial findings anymore, if not
explicitly asked for with the 'serial' option. Without this option, an
invalid ioport is reported, so that neither the kernel nor Genode core
will make serial output.
The screenshot trigger displays a little red dot at the upper-left
corner of the screen. When touched or clicked-on, it generates an
artificial key-press-release sequence for the print key and disappears
for one second. In this time, a separate screenshot component can handle
the print key by capturing the screen without the red dot appearing in
the saved picture.
The touch-keyboard config accepts the new attributes 'opaque="yes"
and 'background=#112233' to control the dialog background. The
attributes are passed unmodified to embedded the menu view.
This patch add the support needed for implementing on-target
system-update functionality. The new 'empty' method is required for the
two-step procedure of updating image-index files - removing the old
index, followed by downloading the most current one. It is used to the
detect the completion of the first step.
Issue #4744
This patch reflects more details such as the percentage value for
downloads maintained in the download queue. This makes this information
easier to display at the GUI.
Issue #4744
This patch replaces the generic "In progress..." message by slightly
more concrete information about the type of operation. This is useful to
distinguish the two steps during the expansion of a partition.
This patch enhances the depot_download subsystem with support for
downloading and querying system images.
The installation ROM support the following two now download types:
<image_index path="<user>/image/index"/>
<image path="<user>/image/<name>"/>
Internally, the depot-download subsystem employs the depot-query
component to determine the missing depot content. This component
accepts the following two new queries:
<images user="..."/>
<image_index user="..."/>
If present in the query, depot_query generates reports labeled as
"images" and "image_index" respectively.
The also tracks the completion of each job depending on the depot-
query results, so that the final report contains a result for each
installation item requested. Prior this patch, the inactivity of the
depot-download manager (indicated by an empty state report) was
interpreted as success. But that prevents the proper association of
results and requested installation items.
Issue #4744
The 'scan' query for depot users used to list the names of depot users.
However, the URL and existence of a pubkey is useful to know when
assembling a GUI menu from this list.
Issue #4744
This patch equips the publish tool to handle system images.
System images reside at <depot-user/image/. The directory contains an
index file that contains the meta information of the available images
in XML form, e.g.,
<index>
<image name="sculpt-pinephone-2023-01-19" board="pinephone">
<info text="initial version"/>
</image>
</index>
To publish a new version of the index:
./tool/depot/publish <depot-user>/image/index
Each system image comes in two forms, a bootable disk image and an
archive of the boot directory. The bootable disk image can be used to
install a new system from scratch by copying the image directly ot a
block device. It contains raw block data. The archive of the boot
directory contains the content needed for an on-target system update to
this version. Within the depot, this archive a directory - named after
the image - that contains the designated content of the boot directory
on target. Depending on the board, it may contain only a single file
loaded by the boot loader (e.g., uImage), or several boot modules, or
even the boot-loader configuration.
To publish both forms:
./tool/depot/publish <depot-user>/image/<image-name>
This results in the following - accompanied by their respective .sig
files - in the public directory:
<depot-user>/image/<image-name>.img.gz (disk image)
<depot-user>/image/<image-name>.tar.xz (boot archive)
<depot-user>/image/<image-name>.zip (disk image)
The .zip file contains the .img file. It is provided for users who
download the image on a system with no support for .gz.
