This patch introduces new types for expressing CPU affinities. Instead
of dealing with physical CPU numbers, affinities are expressed as
rectangles in a grid of virtual CPU nodes. This clears the way to
conveniently assign sets of adjacent CPUs to subsystems, each of them
managing their respective viewport of the coordinate space.
By using 2D Cartesian coordinates, the locality of CPU nodes can be
modeled for different topologies such as SMP (simple Nx1 grid), grids of
NUMA nodes, or ring topologies.
Split the netperf run script into 3 ones so that it can be used more easily
in an automated run.
It is solely for foc_arndale by now.
l4linux_netperf.run - use nic via usb2.0
l4linux_netperf-usb30.run - use nic via usb3.0
l4linux_netperf-bridge.run - use nic via usb3.0 + bridge
* Always download md5sum file and check downloaded binaries
* Extend sleep time in l4linux_netperf script, so that DHCP has enough time
* Fix regexp rule in l4linux_netperf run script to work with MAC addresses
containing only numbers
Fix#787
* Add platform_drv for usb_drv, sd_card_drv and ahci
* Add ahci driver and part_blk on top of it
* add linux instance using SATA partition
* add VIM using SATA partition
In fact, the sizes were the same the whole time, but by using
the same enum in both cases to instantiate the Packet_stream_tx
and Packet_stream_rx members of the e.g. RPC object, it allows
for more flexible generalization between e.g. source or, sink
objects, when programming event-driven, and implementing generic
handlers for their signals.
Don't use the xhci USB host controller for HID and NIC in the l4linux
run script. It doesn't work on the Pandaboard, and isn't needed for the
Arndale board. Moreover, provide a MAC address, and add a providing
rule in the KDB UART driver to supress ugly warnings. Fix#763
With this patch, 'liquid_framebuffer' can be reconfigured at runtime.
The configuration arguments are now provided as XML attributes, matching
those for 'nit_fb'. Furthermore, two new configuration options are added:
<config ...
resize_handle="off" - show/hide a resize handle widget in the lower
right window corner
decoration="on" - show/hide window decoration
(title bar and borders)

This commit simplifies the creation of additional threads and VCPUs in L4linux.
By now, some Genode::Thread_base methods where overridden to use a Fiasco.OC
specific Cpu_session when creating threads.
Recent commit: 297538678e moved the actual creation
of the platform thread into the constructor of the generic Thread_base class.
Thereby the Vcpu class, which extended the Thread_base class, now unnecessarily
created two platform threads for each thread created via Vcpu. Nowadays, the
cpu_session capability is available via the Genode::env() environment. So we can
use the Thread_base parent class for the setup of the platform thread, and
afterwards create a Fiasco.OC specific cpu session client with the same cpu
session capability, Thread_base used for creation, to make use of the L4Linux
specific features of this interface (VCPU enabling, irq object creation etc.).
When L4Linux tries to allocate a dataspace of the size of its physical
memory, this allocation can fail, because the 'l4re_ma_alloc()' function
in the 'l4lx' library always tries to allocate a contiguous dataspace of
the given size and there might be no contiguous free area left.
With this patch, memory gets allocated in chunks: if the size to be
allocated exceeds the configured chunk size, a managed dataspace gets
created and filled with multiple memory chunks of at most the chunk size.
The chunk size is 16M by default and can be configured in an l4linux
config node:
<config args="...">
<ram chunk_size="16M"/>
</config>
Fixes#695.
- search for alternative virtual address regions upwards, starting from
the given start address, in the 'l4re_rm_attach()' and
'Region_manager::reserve_range()' functions
- don't treat memory locations above 0x80000000 in l4linux's virtual
address space as device memory
- align the start address of the vmalloc area according to the assumption
in 'devicemaps_init()'
Fixes#414.
This patch simplifies the way of how Genode's base libraries are
organized. Originally, the base API was implemented in the form of many
small libraries such as 'thread', 'env', 'server', etc. Most of them
used to consist of only a small number of files. Because those libraries
are incorporated in any build, the checking of their inter-dependencies
made the build process more verbose than desired. Also, the number of
libraries and their roles (core only, non-core only, shared by both core
and non-core) were not easy to capture.
Hereby, the base libraries have been reduced to the following few
libraries:
- startup.mk contains the startup code for normal Genode processes.
On some platform, core is able to use the library as well.
- base-common.mk contains the parts of the base library that are
identical by core and non-core processes.
- base.mk contains the complete base API implementation for non-core
processes
Consequently, the 'LIBS' declaration in 'target.mk' files becomes
simpler as well. In the most simple case, only the 'base' library must
be mentioned.
Fixes#18
This patch introduces keyboard-focus events to the 'Input::Event' class
and changes the name 'Input::Event::keycode' to 'code'. The 'code'
represents the key code for PRESS/RELEASE events, and the focus state
for FOCUS events (0 - unfocused, 1 - focused).
Furthermore, nitpicker has been adapted to deliver FOCUS events to its
clients.
Fixes#609
Implement the same semantic like L4Re for the initialization of the initramfs
dataspace. Although, it didn't lead to problems right now, this commit might
prevent future problems.
Open VCPU interrupts while the VCPU is in an IPC operation can badly influence
its state. That's why this commit fixes a whole bunch of places, where IRQs
weren't masked by now.
We have to take the block queue's spin lock before invoking the interrupt
routine, otherwise the AVL tree og Genode's block packet stream gets
corrupted.
When finishing a block request in the L4Linux block stub driver,
we#ve to hold the queue lock before using __blk_end_request_all, or
simply use blk_end_request_all instead. Moreover, this commit simplifies
the lock/unlock behaviour when the block queue has to be stopped, or resumed.
Thanks to I. Ismagilov for these suggestions.
When building the Fiasco.OC kernel, and L4Linux within the Genode build system,
forward the CC, and CXX variables. It might contain useful tools like ccache,
or distcc to speed up compilation. Moreover, don't delete the MAKEFLAGS when
building Fiasco.OC. It hinders parallel builds.
Certain symbols from the libgcc_eh library in cxx that is linked with the
L4Linux kernel were resolved by using kernel internal implementations.
This lead to errors because the complete Linux kernel is built regparm=3.
This patch prefixes the appropriate symbols in the Linux Kernel and its
modules. Moreover, it fixes some warnings introduced by the latest update
to gcc 4.7.
