Because the template instantiation rules of C++ do not deal well with
null pointers specified as '0', the constructor of 'Local_addr' was
instantiated for [T = int], which does not make sense. To avoid the
warning "cast to pointer from integer of different size", we need to
explicitly state that '0' is a pointer. In C++11, there is the 'nullptr'
keyword, but until we switch to this version, we have to state (void *)0.
In usb.inc all required Linux include files of the Linux code are looked up
by 'sed'ing through the files of SRC_C and SRC_CC. The Linux include files
are then added as dependency to the SRC_C and SRC_CC files and during dependency
resolution symbolic links to the lx_emul.h will be created.
In the platform specific usb.mk file there are the Linux driver files
added, but unfortunately after including usb.inc. So, for them no dependency
to any Linux include header file is generated and so no symbolic files are
generated.
If the driver code file is compiled as first, as for asix.c, the symbolic links
of the include files are missing and compilation fails.
Add the Linux driver code files to SRC_C before including usb.inc in the
platform specific usb.mk files.
Originally, a thread was created at core not before calling the 'start'
function. In order to configure the thread affinity before starting the
thread, we have to make the thread known at core right at construction
time. This patch moves the needed thread-creation sequence from the
'start' function to the '_init_platform_thread' function.
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.
Don't do anything in Mapping::prepare_map_operation. At this point and in the
current implementation, the memory has been mapped and cleared already. Touching
the memory may only pollute the cache causing data corruption in DMA memory.
Fixes issue #452
The KDB UART driver uses the Fiasco(.OC) kernel debugger console as backend
for input and output. This is useful in the case that only one UART is
available.
Fixes#665.
In this version of the transition the Hip structure from Genode is reused,
@nfeskes seoul_libc_support is used for the string functions and the
nul/config.h is replaced by just using a constant value in the one place where
the file was needed.
Related to #666.
- 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.
Explicitly set default mode for legacy interrupts to not rely on kernel
default settings. This patch fixes the constantly busy IRQ threads for
IRQ 1 and 12 as soon as the PS/2 driver was loaded until the point when
the first IRQ occurred.
Remove the 'epit' variable from the generic imx31 and imx53 specification,
and only add it to base-hw specific i.MX specs. Thereby the EPIT timer
library gets build for base-hw only.
Moreover, fix some const-ness issues in the platform_timer implementation
for the EPIT timer.
Fixes#688.
The new core-internal 'Address_space' interface enables cores RM service
to flush mappings of a PD in which a given 'Rm_client' thread resides.
Prior this patch, each platform invented their own way to flush mappings
in the respective 'rm_session_support.cc' implementation. However, those
implementations used to deal poorly with some corner cases. In
particular, if a PD session was destroyed prior a RM session, the RM
session would try to use no longer existing PD session. The new
'Address_space' uses the just added weak-pointer mechanism to deal with
this issue.
Furthermore, the generic 'Rm_session_component::detach' function has
been improved to avoid duplicated unmap operations for platforms that
implement the 'Address_space' interface. Therefore, it is related to
issue #595. Right now, this is OKL4 only, but other platforms will follow.
This enables us to use the run scripts applied to a native machine equipped
with Intel's AMT. If the environment variables are correctly set up, the remote
test machine is reseted via 'amttool', then via 'amtterm' the serial output
is collected and the normal run script matching pattern for success/failure of
the run script are applied.
'amttool' and 'amtterm' are part of the package called 'amtterm' shipped with
the Linux distributions like Ubuntu, Debian and lot more.
Following environment variables are required, to run the run scripts with a
native AMT test machine:
PXE_TFTP_DIR_BASE - absolute path of TFTP directory
PXE_TFTP_DIR_OFFSET - relative path to PXE_TFTP_DIR_BASE where the config file
will be generated - named 'config-00-00-00-00-00-00'
AMT_TEST_MACHINE_IP - TCP/IP address of target AMT test machine
AMT_TEST_MACHINE_PWD - password of target AMT test machine
Issue #679
Since checking if the certificate is valid is not that important
(we currently do not check the signature of the archive which is the
bigger issue) we disable the checking to prevent certain wget version
from refusing to download the archive.
Fixes#681
mkisofs is the original ISO creation tool from cdrtools available on
many UNIX systems. genisoimage on the other hand is part of a mostly
unmaintained fork of cdrtools very specific to Debian Linux and its
derivates (e.g., Ubuntu). Fortunately, genisoimage (as we used it) is
completely invocation-compatible to mkisofs.
Fixes#627.
