[Bug 90079] drmSetMaster and drmDropMaster need root privileges
by bugzilla-daemon＠freedesktop.org 14 Oct '19

14 Oct '19

https://bugs.freedesktop.org/show_bug.cgi?id=90079 Bug ID: 90079 Summary: drmSetMaster and drmDropMaster need root privileges Product: DRI Version: unspecified Hardware: All OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: libdrm Assignee: dri-devel(a)lists.freedesktop.org Reporter: g1938560(a)trbvm.com I run a small, user-space program that renders images in my virtual console with drmModeSetCRTC and family. I also support virtual terminal switching with ioctl() on stuff from linux/vt.h and some basic signal handling. Switching back to X server, however, just renders... nothing. Apparently I'm supposed to call drmDropMaster so that X server can pick up from there. I get -1 and errno is set to Permission Denied. When run as root, it works as expected. Is there any reason why these functions require root privileges? More importantly, is there any workaround for this so that my user space program can let X server draw its stuff once user switches back to X's virtual terminal? -- You are receiving this mail because: You are the assignee for the bug.

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.

If, i tweak drm_edid.c from kernel-2.6.39-gentoo-r1 like this: --- drm_edid.c 2011-06-10 22:37:36.605848000 +0200 +++ linux/drivers/gpu/drm/drm_edid.c 2011-06-13 13:04:43.136786102 +0200 @@ -292,7 +292,7 @@ block + (valid_extensions + 1) * EDID_LENGTH, j, EDID_LENGTH)) goto out; - if (drm_edid_block_valid(block + (valid_extensions + 1) * EDID_LENGTH)) { + if (drm_edid_block_valid(block + (valid_extensions + 0) * EDID_LENGTH)) { valid_extensions++; break; } that work good like before but i'm not sure that is safe. More info in http://lists.freedesktop.org/archives/nouveau/2011-June/008548.html I can post logs here too , just tell me.
