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
Implement GLX and X functionality through Mesa's EGL interface. This
requires multiple OpenGL contexts and in turn GEM context support in
libdrm/iris, as implemented in libdrm and intel_gpu_drv.
Update recipes and machine.vbox6 files accordingly,
issue #4380
To actually receive audio input in a particular VM, it also
needs to be enabled in the vbox file:
<AudioAdapter controller="HDA" driver="OSS" enabled="true"
enabledOut="true" enabledIn="true"/>
Fixes#4377
There are some subtle incompatibilities in VirtualBox 6 with settings we
used in version 5. Therefore, the vbox6 package uses machine.vbox6 as
configuration file. An example configuration is provided by the
raw/vbox6 package.
Issue #4281
The service is loaded dynamically VBoxSharedClipboard.so at runtime. The
VFS configuration mounts the shared object at /VBoxSharedClipboard.so as
the file is checked by contrib code before loading. An init
configuration in pkg/vbox6/runtime illustrates this and how to re-label
the VBoxSharedClipboard.so ROM to its real name
virtualbox6-sharedclipboard.lib.so.
In ROM mode the global CapsLock state is controlled by the capslock ROM
by virtual KEY_CAPSLOCK events.
Guests are easily confused by spurious KEY_CAPSLOCK input events in
caps="rom" mode. These spurious events may reach the VMM if KEY_CAPSLOCK
is not pressed as first key in a combination and, therefore, is not
filtered as global key. We filter KEY_CAPSLOCK in ROM mode in the VMM
explicitly, but let it pass in non-ROM mode.
Per default RAW mode is used and CapsLock key events are sent unfiltered
to the guest.
