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 ...).').
issue #5104
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>.
Fix#4081
I2C EEPROMs of the type at24xxx are really slow (ca. 10 kHZ).
This adds the `bus_speed_khz` attribute to the config of the driver and
adapts the i.MX8 driver to support the feature.

Fixes genodelabs#5090
The physical address of the memory used for the guest VMCB is already
present in Vcpu_data. Use the information there instead of storing the
physical address in the host data area, thereby freeing up 8 bytes for
a bigger Mmio class.
Issue #4081
Hitting a BOSD in a Windows guest in Virtualbox 6 leads to calling
`DBGFR3ReportBugCheck`, which leads to the following error since it is
unimplemented in our port:
```
Error: DBGFR3ReportBugCheck: DBGFR3ReportBugCheck called, not implemented, eip=0x1a5c4e4
```
Including the actual method from Virtualbox 6 enables logging
diagnostics for the Windows Blue Screen of Death (BSOD).
To see Blue Screen logging output, enable "dbgf" and "gim" logging
via the `VBOX_LOG` following environment variable in the vbox6 runtime
config.
When manually triggering a BSOD in the Windows guest, this should
produce the following logging diagnostics:
```
GIM: HyperV: Guest indicates a fatal condition! P0=0xe2 P1=0x0 P2=0x0 P3=0x0 P4=0x0
GIMHv: BugCheck e2 {0, 0, 0, 0}
MANUALLY_INITIATED_CRASH
```
Fixes#5099
The libc's internal calculation of the tv_sec and tv_nsec fields must be
based on the same ms value. Otherwise, tv_sec is not always immediately
incremented whenever tv_nsec wraps. For applications, this inconsistency
can result in observed jumps in time.
Fixes#5098
Functions registered with 'module_init' (i.e., '__define_initcalls'),
'OF_DECLARE', and 'DECLARE_PCI_FIXUP_CLASS_FINAL' used to be static
constructors and had be explicitly registered using
'exec_static_constructors' before executing any Linux code.
With this commit we remove the constructor attributes from these
functions and create a global function pointer in the form of
__initptr_<name>_<id>_<counter>_<line number of macro>
'import-lx_emul_common.inc' will collect these '__initptr' symbols after
the compile step and generate a 'lx_emul_register_initcalls' function
that executes the functions pointed to. This step is now automatically
performed in 'lx_emul_start_kernel'. This way a call to
'exec_static_constructors' can be omitted in case there are no other
constructors in place.
issue #5096
The former implementation relied on input drvdata always pointing to
struct hid_device, which is not true for Wacom touch devices (at least).
Now, we implement the input handler for devices providing LEDs
(evbit[EV_LED] set) only and use input_inject_event() to set the LED
states.
This commit brings the etnaviv back end implementation in line
with the one from lima. Since the etnaviv driver itself handles
different contexts implicitly rather explicitly like lima and
iris for the moment only a main-context is used for all operations.
