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.
Issue genodelabs/genode-imx#8.
Uploading large files via HTTP PUT failed when the file system was
accessed via a file system session because lighttpd opened the
destination file with O_NONBLOCK and the write operation stalled
at some point.

These domains allow for the hosting of plain http and telnet servers
reachable from the outside. The change is designated for the goa
testbed.
Issue #5092
The commit is a preparation commit for suspend/resume. It prepares the GPU
structures relying on gmadr.cap() (MMIO) to be re-constructible by applying
the with* pattern to context, ring_buffer and ggtt mmio map. It removes
the managed dataspace handling of gmadr subsets to make the with_* pattern
possible.
Issue #5081
This commit is a preparation commit for suspend/resume. The commit
refactors the code in order to consolidate all Platform resources into one
instance. All users within the GPU driver should access the resources with
with_* functions, which checks whether the device resource is usable. The
callers are not allowed to store any references to the provided resources.
With this change, it will be possible in follow up commits, to release
the platform device and to re-acquire it and its resources, e.g. mmio, irq,
gmadr.
Issue #5081
- add PS/2 input drivers
- add GPU client test case - glmark2
- remove display driver before suspend
- route log output via terminal on display to gather information, since in
most cases serial/AMT is not available after ACPI resume
Issue #5081
Clearing very large RAM dataspaces could fill up core's page table,
because the dataspaces are locally mapped to clear them.
This would manifest in a loop where exhausting the local page table
leads to its flushing (which does not work for core) and a retry that
again fills up the page table and so on.
To prevent this, flush RAM dataspaces in chunks of at most 128MiB.
Fixes#5086
If "verbose" is set to true in the config, AcpiOsPrintf etc. are enabled
to log to a dedicated LOG session using the Format:Console utility.
Issue #5083
Prevent errors if precision and left alignment are part of the string.
String precision is applied to limit access to the configured number of
characters but ignored for other types.
Issue #5083
The axis IDs correspond to 2x analog sticks with 2 axes and 2x triggers.
While being at it, the commit changes the Axis_id type to Axis::Id.
Fixes#3669
Failed allocations were still denoted with a successful return value
to the caller. This situation was triggered by artificial testing and
has not been observed yet in practice. In case the 'LIMA_GEM_CREATE'
I/O control fails Mesa will dereference invalid pointers anyway.
Issue genodelabs/genode-allwinner#27.
The frame-pointer-based backtrace does not work without enabling
-fno-omit-frame-pointer explicitly and in most cases leads to page
faults because non-pointer stack values are dereferenced during the
walk. The best we can do is to limit the backtrace walk to the stack of
the current thread to prevent page faults unrelated to the system state
without the use of the backtrace utility.
This commit introduces a printable Backtrace class usable in
Genode::log(), Genode::trace(), etc. The class is based on the new
function for_each_return_address(auto const &fn) that walks the stack in
its limits and calls fn() for each discovered return address on the
stack in the new os/include/os/backtrace.h. Archtecture-specific
stack-pointer retrieval and walk loops are implemented in dedicated
os/include/spec/<arch>/os/for_each_return_address.h files. Also, the
well-known Genode::backtrace() function (which logs the return-address
values) is provided for backwards compatibility.
Fixes#5078
