pci_channel_offline() checks if this member is set to
pci_channel_io_normal (which is 1). The former value of 0 is invalid.
This change fixes pc_nic_drv link down-up in cases that require an e1000
reset.
lx_emul_trace_msg() uses Genode::trace() as message function for
lightweight trace points, but also supports Linux format-string
attributes by using vsnprintf().
This is function gets called by some libssh applications using vms_lxip.
For the dummy implementation I looked at the old port.
Issue genodelabs#5161
Issue gapfruit#1976
The added hook 'OBJ_POSTPROC_SRC' gives us a way to post-process object
files for generating supplemental code. By using this hook, the
initcall_table.c generated by import-lx_emul_common.inc gets reliably
executed after all object files are built.
Fixes#5159
The option is used during the generation of initcall_table.c.
However, it happens to strip the first argument following the option.
The long option --defined-only works as expected.
Issue #5155
Replace the USB session API by one that provides a devices ROM only,
which contains information about all USB devices available for this client,
as well as methods to acquire and release a single device.
The acquisition of an USB device returns the capability to a device session
that includes a packet stream buffer to communicate control transfers
in between the client and the USB host controller driver. Moreover,
additional methods to acquire and release an USB interface can be used.
The acquisition of an USB interface returns the capability to an interface
session that includes a packet stream buffer to communicate either
bulk, interrupt, or isochronous transfers in between the client and the
USB host controller driver.
This commit implements the API changes in behalf of the Genode C API's
USB server and client side. Addtionally, it provides Usb::Device,
Usb::Interface, and Usb::Endpoint utilities that can be used by native
C++ clients to use the new API and hide the sophisticated packet stream API.
The adaptations necessary target the following areas:
* lx_emul layer for USB host and client side
* Linux USB host controller driver port for PC
* Linux USB client ports: usb_hid_drv and usb_net_drv, additionally
reduce the Linux tasks used inside these drivers
* Native usb_block_drv
* black_hole component
* Port of libusb, including smartcard and usb_webcam driver depending on it
* Port of Qemu XHCI model library, including vbox5 & vbox6 depending on it
* Adapt all run-scripts and drivers_interactive recipes to work
with the new policy rules of the USB host controller driver

Newer Qemu variants quit with an error about already existing devices
if the same device-id is add and removed in a loop fast. To circumvent
this strange behaviour, simply use consecutive device id numbers.

A read with MSG_PEEK returns -1 and EGAIN/EWOULDBLOCK in case the socket
is connected. Zero is only returned if the socket is disconnected.
isuee #5104
The key element of the improvement is differentiated processing of
events of the following device types.
Mouse: relative motion
Pointer: absolute motion (Qemu usb-tablet and IP-KVM devices)
Touchpad: relative motion via absolute touchpad coordinates
Touchtool: absolute motion (e.g., stylus)
Touchscreen: absolute motion and finger (multi-) touch
Processing is done in two stages for one "input packet". First, all
events of the packet are recorded into the current evdev state with
device-type specific operations. Then, appropriate Genode input events
are generated from the accumulated evdev state in the submission stage
(again by device-type specific functions).
A simple version of tap-to-click was added to the touchpad support.
Fixes#5105
This commit enables generic Linux multi-touch support as well as support
for the Wacom Intuos/Graphire tablets as found in the previous version
of the USB HID driver. Events are not properly propagated through
Genode's Event C-API, yet, which will be a follow up.
Issue #5105
When SMP is enabled multicore specific instructions (e.g., pldw) are
generated. These are not supported and lead to invalid instruction
faults on uni-processor systems (like Cortex-A8). Therefore, we disable
SMP for arm_v7 in Linux code. This requires also a switch from the RCU
tree implementation to RCU tiny, which we shadow and dummy implemented.
issue #5104
Until now, in case 'jent_entropy_init' failed an error has been produced
and the following jitterentropy functions (i.e.,
'jent_entropy_collector_alloc') where called nevertheless. In case we
received a bad time source error, for example because the performance
counters are not working on the platform, the entropy collector did not return (endless
loop).
Therefore, this commit treats the failed jitterentropy initialization
not as an error but prints a warning about poor randomness quality and
stops using the jitterentropy library from this point on. The
'Jitterentropy::gen_random_u64' will in this case return the address of
a stack variable * some counter.
This is only a interim solution to make platforms work where performance
counters or TSC values do not exist/work.

Adjust the plugin to use the socket C-API found under
dde_linux/src/lib/lxip/include/genode_c_api/socket.h'.
This is the first minor step in generalizing the plugin.

The lxip_raw.run script will spawn a client/server scenario that tests
Genode C-API calls. The scenario can be used standalone, meaning no
actual network card is required.
issue #5104
This commit updates lxip from version 4.4.3 to 6.1.20. It uses the
current lx_kit approach and is a shared library again. The stack has
been tested for x86_32/x86_64/arm_v6/arm_v7/arm_8.
The C-interface of the IP stack can be found under
lxip/include/genode_c_api/socket.h.
issue #5104
CONFIG_X86_USE_PPRO_CHECKSUM is a 'def_bool y' and gets re-enabled by
'make olddefconfig'. The PPRO version contains text relocations which we cannot
have in binaries (e.g., 'lea 45f(%ebx ...).').

add bottom half enable/disable to functions with suffix "_bh" were
missing, because some functions release the bottom half separately
(__neigh_event_send).
issue #5104
Add the possibility to execute a module-init call by name using
'lx_emul_init_call', this is used, for example, by lxip to configure and
re-configure the IP address through 'ip_auto_config'.
issue #5104
The classes Genode::Mmio, Genode::Register_set, Genode::Attached_mmio, and
Platform::Device::Mmio now receive a template parameter 'size_t SIZE'. In each
type that derives from one of these classes, it is now statically checked that
the range of each Genode::Register::Register- and
Genode::Register_set::Register_array-deriving sub-type is within [0..SIZE).
That said, SIZE is the minimum size of the memory region provided to the above
mentioned Mmio classes in order to avoid page faults or memory corruption when
accessing the registers and register arrays declared inside.
Note, that the range end of a register array is not the end of the last item
but the end of integer access that is used for accessing the last bit in the
last item.
The constructors of Genode::Mmio, Genode::Attached_mmio, and
Platform::Device::Mmio now receive an argument 'Byte_range_ptr range' that is
expected to be the range of the backing memory region. In each type that derives
from on of these classes, it is now dynamically checked that 'range.num_bytes
>= SIZE', thereby implementing the above mention protection against page faults
and memory corruption.
The rest of the commit adapts the code throughout the Genode Labs repositories
regarding the changes. Note that for that code inside Core, the commits mostly
uses a simplified approach by constructing MMIO objects with range
[base..base+SIZE) and not with a mapping- or specification-related range size.
This should be fixed in the future.
Furthermore, there are types that derive from an MMIO class but don't declare
any registers or register arrays (especially with Platform::Device::Mmio). In
this case SIZE is set to 0. This way, the parameters must be actively corrected
by someone who later wants to add registers or register arrays, plus the places
can be easily found by grep'ing for Mmio<0>.
