This patch replaces the use of the "Framebuffer" session interface by
the new "Capture" session interface in all framebuffer drivers. Thanks
to this change, those drivers have become mere clients of the nitpicker
GUI server now, and are no longer critical for the liveliness of the GUI
server.
The patch touches the following areas:
- The actual driver components. The new versions of all drivers have
been tested on the respective hardware. Generally, the drivers
have become simpler.
- The drivers_interactive packages for various boards. The drivers
subsystem no longer provides a "Framebuffer" service but needs a
valid route to the "Capture" service provided by nitpicker.
- The driver manager of Sculpt OS.
- This patch changes the role of the test-framebuffer component from a
framebuffer client to a capture server so that drivers (capture clients)
can be directly connected to the test component without the nitpicker
server.
- Framebuffer driver no longer support the unbuffered mode.
- The fb_bench.run script is no longer very meaningful because it
interplays solely with nitpicker, not with the driver directly.
- All run scripts for graphical scenarios and the related depot
archives got adapted to the change.

* Differentiate in between different architectures with assembler routines
for correct measures
* Automate first step measuring of 10G bogomips across different hardware
Fix#3785
Until now, Genode's framebuffer session interface was based on the
RGB565 pixel format. This patch changes the pixel format to 32-bit
XRGB where the X part is ignored. It adapts all graphical applications
and device drivers accordingly.
The patch also adjusts the users of the drivers_interactive packages,
assigning 64 MiB RAM and 1500 caps to the drivers subsystem, which is
sufficient for covering high resolutions at 32 bits per pixel and to
accommodate multi-component USB HID input stacks.
Fixes#3784
The 'vfs_block' component will give access to a VFS file through a
Block session. For more detailed information please look at its
README.
(On a technical note, the server currently only allows for one
active session and has only one pending back end request but can
easily be extended in the future.)
Fixes#3781.
This patch removes old 'Allocator_guard' utility and replaces its use
with the modern 'Constrained_ram_allocator'.
The adjustment of core in this respect has the side effect of a more
accurate capability accounting in core's CPU, TRACE, and RM services.
In particular, the dataspace capabilities needed for core-internal
allocations via the 'Sliced_heap' are accounted to the client now.
The same goes for nitpicker and nic_dump as other former users of the
allocator guard. Hence, the patch also touches code at the client and
server sides related to these services.
The only remaining user of the 'Allocator_guard' is the Intel GPU
driver. As the adaptation of this component would be too invasive
without testing, this patch leaves this component unchanged by keeping a
copy of the 'allocator_guard.h' locally at the component.
Fixes#3750
- don't use 'qemu -serial mon:stdio' anymore as it no longer works as
expected
- use "bash -l" with [terminal] to read user's profile configuration,
e.g., PATH settings
- added missing boot modules and cap quotas
As a result of the API change the memory handling could be simplified.
Since the Block session dataspace is now directly used for DMA, we
actually only have to provide the memory for setting up PRP lists for
large requests (for the moment more than 8 KiB of data).
As we limit the maximum data transfer length to 2 MiB, we get by with
just a page per request. Those memory is allocated beforehand for the
maximum number of I/O requests, which got bumbed to 512 entries. Since
not all NVMe controllers support such large a maximum data transfer
length and this many entries, especially older ones, the values are
capped according to the properties of the controller during
initialization. (The memory demands of the component are around 3 MiB
due to setting up for the common case, even if a particular controller
is only able to make use of less.)
(Although there are controllers whose maximum memory page size is more
than 4K, the driver is hardcoded to solely use 4K pages.)
In addition to those changes, the driver now supports the 'SYNC' and
'TRIM' operations of the Block session by using the NVMe 'FLUSH' and
'WRITE_ZEROS' commands.
Fixes#3702.
This patch fixes a regression with run/log_core introduced by
2064ffd64b nova: support multidimensional affinity space
The run tool uses a log message 'run_boot_string' to detect successful
boot as well as to detect unexpected reboots. This message should never
be logged twice and, thus, should not be part of the core_log. The patch
mentioned above moved the former run_boot_string after the core_log
initialization.
- use two disks with two partitions each
- one disk uses MBR and one GPT
- connect one 'part_block' to each disk
- run 'block_tester' and 'test-block-client' connecting to one partiion
on each disk
- x86 uses 'ahci_drv' as disk back-end, Linux 'lx_block'
- on autopilot enable for Qemu only
issue #3671
- Remove dated 'Block::Driver' front end and implement
'Block::Request_stream' front end
- Remove all dynamic memory allocations but DMA memory allocations
- Remove 'Platform_hba' and implement platform specific functions in
'spec/<platform>/*'
- Ata and Atapi don't inherit from 'Port' any more, but are a member of
'Port' as a protocol implementation
- Use platform driver for MMIO mappings (x86)
- Exchange stateful initialization of Ata/Atapi with a sequential
initialization using 'wait_for_any' and 'retry' patterns
- Fix Atapi initialization by setting the byte count limit
- Set FIS receive base only when Cmd::FRE is disabled and Cmd::FR is 0
- Put everything in namespaces ('Ahci', 'Ata', or 'Atapi')
- Ata decides during read/write operations to use native-command queuing
or normal DMA requests
- Remove port claiming logic (is now done via 'Constructibles')
fixes#3636
This patch extracts the child-management functionality from the init
component into a new library called "sandbox". The library API is
located at 'os/include/os/sandbox.h'.
The sandbox API allows for the interaction of the component with the
sandboxed children by providing locally implemented services. This
mechanism is illustrated by the new test at os/src/test/sandbox.
Issue #3601
When re-configuring a domain from using a static IP config to using a dynamic
IP config, attached interfaces didn't react with doing DHCP discover. This bug
is fixed now and the nic_router_flood test was adapted in a way that it tests
the described behavior.
Fix#3518
The rtc_drv on x86 can now by used to also set the RTC. If the config
attribute 'allow_setting_rtc' is set to 'yes' the driver will update
the RTC from the content of the 'set-rtc' ROM module. A valid ROM must
contain a top node with the following attributes: 'year', 'month',
'day', 'hour', 'minute' and 'second'.
* Only rudimentary checking of the provided values is done.
* '12H' mode is not supported.
Fixes#3438.
On some platforms (foc+pbxa9, hw+imx53_qsb_tz, hw+rpi) the default buffer size
is to much for the RAM available on the board. Thus, decrease the buffer size
and therefore the number of polls for these platforms only.
Fixes#3354
Moreover, express current requirement to hw API, which was missing until now.
Originally, in the board-specific build directory of imx53_qsb the
"KERNEL" variable was preset with "hw". Therefore, it was not perceived
that this dependency is required.
