This patch revives our ds_ownership test from 2012, which just revealed
a regression in core where the dataspace-free operation of the RAM
service would unconditionally destroy dataspace objects from foreign
sessions. The patch fixes the bug and adds an updated version of the
test to the autopilot.
Fixes#2065
The main feature for this version upgrade is the use of the instruction
emulator (IEM) to speed up execution and less often the slow recompiler.
issue #2059
Besides adapting the components to the use of base/log.h, the patch
cleans up a few base headers, i.e., it removes unused includes from
root/component.h, specifically base/heap.h and
ram_session/ram_session.h. Hence, components that relied on the implicit
inclusion of those headers have to manually include those headers now.
While adjusting the log messages, I repeatedly stumbled over the problem
that printing char * arguments is ambiguous. It is unclear whether to
print the argument as pointer or null-terminated string. To overcome
this problem, the patch introduces a new type 'Cstring' that allows the
caller to express that the argument should be handled as null-terminated
string. As a nice side effect, with this type in place, the optional len
argument of the 'String' class could be removed. Instead of supplying a
pair of (char const *, size_t), the constructor accepts a 'Cstring'.
This, in turn, clears the way let the 'String' constructor use the new
output mechanism to assemble a string from multiple arguments (and
thereby getting rid of snprintf within Genode in the near future).
To enforce the explicit resolution of the char * ambiguity, the 'char *'
overload of the 'print' function is marked as deleted.
Issue #1987
Core on seL4 is configured to run on native hardware, so some static
allocators are bit over dimensioned. Some run scripts fail on qemu because
solely 64M are available in the system - adjust the affected scripts.
Issue #2044
The initial support reports TouchPointPressed, TouchPointMoved, and
TouchPointReleased for multiple touch points, but is currently only
tested with widgets not leveraging multi-touch events. In other words, I
made sure synthetic mouse events are generated properly when using touch
screens.
We now always run the input_merger as Input service provider and
configure backends suitable for the used platform. On x86 hardware, we
enable both, PS/2 and USB HID.
Required to boot on hardware. The fragmentation is such unfortunate with the
old allocator that alloc() will throw an exception during very early core boot
phase.
Issue #2044
- disable iommu
- increase root_cnode further for native boot
- support vesa driver on native hardware
- don't mask edge triggered ioapic irqs
- increase various allocators to get noux_tool_chain_* booting natively
Issue #2044
That seems nowadays the right place in order to tell the caller that the
thread couldn't be completely constructed. The return value false of
bind_thread causes in Cpu_thread_component the throwing of
Thread_creation_failed.
thread.run now passes
pthread.run now passes
