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)
/>
Fixes#740Fixes#14
Print Fiasco.OC kernel debugger messages into a file instead of a pipe
in the default l4linux run-script. Thereby rarely triggered issues by the
nightly running buildbot can be analyzed after the test failed.
The memory allocation heuristics in the usb driver provided by dde_linux
changed with the recent commit 71b2b42936.
Apparently, the new variant requires a larger memory pool. Increasing
the quota is a temporary fix until the memory allocator gets revisited.
This commit comprises the following changes to enable L4Linux to use several
CPUs:
* change default configuration for x86 and ARM
* add atomic cmpxchg operation to l4re library
* implement l4_sleep (per thread)
* enable setting affinity for VCPUs and IRQs
* move "per CPU" section within linker-script (x86 only)
* introduce SMP run-script for pandaboard
* deactivate direct scheduler (Fiasco.OC syscall) access by L4Linux
The additional quota is needed because of the recent performance
optimizations of the USB/networking code, e.g., to support the
increased NIC packet-stream buffer size.
Use terminals for LOG output of L4Android scenario, as well as a terminal
session for the Linux terminal. Now everything can be used interactively
on one screen: the Linux/Android framebuffer, the Linux console, and the
LOG-output of L4Linux.
When introducing an avl-tree to re-find known capabilities in Fiasco.OC
(issue #112), the memory demand of apllications was slightly increased.
So we've to give the pl11x driver more memory by default. Fixes#140.
The old variant provided 8K capability slots to all processes on core,
which increased binaries by 180 KB for the static allocator. I reduced it
to 4K capabilities stay under 100 KB overhead for the allocator.
Anyway, pci_drv and pl11x_drv need more RAM quota now: 2M for pl11x_drv
and 1M for pci_drv.
