[Bug 89549] DisplayLink (udl) Linux kernel memory fault on USB hot unplug, proposed patch
by bugzilla-daemon＠freedesktop.org 14 Oct '19

https://bugs.freedesktop.org/show_bug.cgi?id=89549 Bug ID: 89549 Summary: DisplayLink (udl) Linux kernel memory fault on USB hot unplug, proposed patch Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/other Assignee: dri-devel(a)lists.freedesktop.org Reporter: adam_richter2004(a)yahoo.com Created attachment 114235 --> https://bugs.freedesktop.org/attachment.cgi?id=114235&action=edit Add ".get_vblank_counter = drm_vblank_count," to DisplayLink drm_driver functions [This is an edit of an email that I sent yesterday to linux-fbdev at vger.kernel.org and the Linux kernel udlfb maintainer.] In Linux-4.0-rc3, the DisplayLink driver gets a kernel memory fault when its USB device is unplugged, specifically when vblank_disable_and_save in linux-4.0-rc3/drivers/gpu/drm/drm_irq.c attempts to call the NULL function pointer dev->driver_get_vblank_counter. linux-4.0-rc3/Documentation/DocBook/drm.tmpl says of that field, "Otherwise drivers can use the drm_vblank_count helper function to handle this operation." Trying that seems to have eliminated the oops when I unplug the device, although I do see these lines in the console log at device driver initialization time that I think are probably fine, but which I should mention in case the indicate that I did the wrong the thing: [drm] Supports vblank timestamp caching Rev 2 (21.10.2013). [drm] No driver support for vblank timestamp query. If that doesn't look like a problem, then please apply the attached patch and push it upstream. The patch just adds one line that appears in six other framebuffer drivers to initialize the driver_get_vblank_counter drm_driver function. Thanks in advance for your attention to this problem. -- You are receiving this mail because: You are the assignee for the bug.
