This patch clears the terminal each time the menu appears and thereby
wipes away artifacts that might occur when combining terminal_mux with
kdb_uart_drv and the kernel prints messages directly.
This fixes issues with several HID keyboards by implementing
get_unaligned_le16(), which obviously may also fix other not-yet-known
issues. Hint: I had to look out for suspicious lines like follows in the
verbose log.
[init -> usb_drv] get_unaligned_le16 called, not implemented
Also, quirks for cherry keyboards are now applied.
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.
