This commit removes an endless loop, that occurred when the sd_card driver
called usleep, or msleep on its Timer_delayer object. Fixes#705
Also fixes the same problem for the Omap4 GPIO driver.
'Gratuitous ARP' broadcast messages are used to announce newly created
IP<->MAC address mappings to other hosts. nic_bridge-internal hosts
would expect a nic_bridge-internal MAC address in this message, whereas
external hosts would expect the NIC's MAC address in this message.
The simplest solution to this problem is to just drop those messages,
since they are not really necessary.
Fixes#709.
This patch adds the consideration of suddenly disappearing managed
dataspaces in the 'Rm_session_component::reverse_lookup' function.
Previously, this case resulted in a seamingly valid translation.
Fixes#701
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 destroying a thread, which was not bound to a protection domain via kernel
primitives beforehand, it is critical to change the pager and exregs the thread
in the destruction process. Therefore, this commit introduces two thread states:
DEAD and RUNNING. On the basis of the thread state, we can decide whether to
reset the thread before destroying it, or not.
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.
