New Revision: 328436
URL: https://svnweb.freebsd.org/changeset/base/328436
Log:
Decouple Linux files from the belonging character device right
after open
in the LinuxKPI. This is done by calling finit() just before
returning a magic
value of ENXIO in the "linux_dev_fdopen" function.
This breaks DRI3 (uses DMABUF) on drm-next-kmod (Linux 4.9 atm) e.g.,
$ LIBGL_DRI3_ENABLE=1 LIBGL_DEBUG=verbose MESA_DEBUG=context glxgears
libGL: screen 0 does not appear to be DRI3 capable
libGL error: Connection closed during DRI3 initialization failure
XIO: fatal IO error 35 (Resource temporarily unavailable) on X server
":0"
after 22 requests (22 known processed) with 0 events remaining.
Hi,
I'll have a look. It might be an issue in libdrm, because it uses some
out-of date methods to enumerate the device nodes, like the major and
minor numbers.
Did you recompile drm-next-kmod after recompiling the LinuxKPI?

Hi,
I'm still running:
freebsd-base-graphics
g...@github.com:FreeBSDDesktop/freebsd-base-graphics.git
With r328436 applied on top and glxgears work:
env LIBGL_DRI3_ENABLE=1 LIBGL_DEBUG=verbose MESA_DEBUG=context glxgears
libGL: OpenDriver: trying /usr/local/lib/dri/i965_dri.so
libGL: Can't open configuration file /home/hans/.drirc: No such file or
directory.
libGL: Using DRI2 for screen 0
libGL: Can't open configuration file /home/hans/.drirc: No such file or
directory.
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
302 frames in 5.0 seconds = 60.252 FPS
Can you do a ktrace and see where it stops?
