Synchronize GPU completion by calling 'read' of the vfs_gpu plugin. This
enables pthreads to wait for GPU completions instead of the main EP.
issue #4380
This commit removes the report service from the usb_webcam pkg, which
was used to enable or disable the webcam driver. The on/off state is
instead controlled by the presence of a capture client. That is, once a
capture client appears, the webcam driver is started. Vice versa, once
no capture client exists, the webcam driver is removed automatically.
Internally, the detection of presence of a capture client is based on
nitpicker's 'displays' report, which is consumed as input of the
rom_filter, which in turn generates the configuration of a dynamic sub
init.
Fixes#4287
By using the cached_fs_rom instead of fs_rom, each client obtains the
same (read-only) copy of the shared library, avoiding a RAM resource
request when running mulitple GPU applications at the same time.
With this patch, Sculpt is able to host at least 3 Mesa applications.
Issue #4263
Issue #4281
This new version of the system_clock pkg does no longer depend on the
presence of an external 'Rtc' service as previously provided by the
Sculpt base system. Instead, it hosts the rtc_drv inside the subsystem.
Because rtc_drv is board-dependent, the system_clock pkg is named
system_clock-pc now.
Issue #4281
* Switch mesa support from DRI to gallium
Supported drivers are
- softpipe (Sebstian Sumpf)
- iris for Intel GPUs (Alexander Boetcher)
- etnaviv for Vivante GPUs (Josef Söntgen)
* Mesa's generated files are placed into 'contrib/mesa-<hash>/generated'
and are cloned per default from a separate Git repo in order to avoid
hash updates upon package build. In case you need to generate files
yourself use
! prepare_port mesa GENERATE_FILES=1
issue #4254
Support for iris and etnvaviv
* entaviv:
- libdrm on FreeBSD is not prepared for !PCI (and libc our is missing
<sys/pciio.h>
- missing <sys/types.h> include in xf86drmMode.c
- etnaviv relies on linux header files - dummy in $(INC_DIR)
- IOCTL FreeBSD ↔ Linux have swapped IO/OUT bit
- O_CLOEXEC differs between FreeBSD ↔ Linux
