[Bug 101998] X server 1.19.3 failure with amdgpu (radeon M295X) on Ubuntu HWE16.04 kernel 4.10.0-28
https://bugs.freedesktop.org/show_bug.cgi?id=101998 Michel Dänzer changed: What|Removed |Added CC||ago...@nvidia.com Assignee|xorg-driver-ati@lists.x.org |xorg-t...@lists.x.org Component|Driver/AMDgpu |Driver/modesetting --- Comment #37 from Michel Dänzer --- I was able to reproduce the problem. It's a modesetting driver bug, this code in ms_dirty_update: msPixmapPrivPtr ppriv = msGetPixmapPriv(&ms->drmmode, ent->slave_dst); probably needs to be: msPixmapPrivPtr ppriv = msGetPixmapPriv(&ms->drmmode, ent->slave_dst->master_pixmap); otherwise it tries to access random memory when the slave screen doesn't use the modesetting driver. There might be more related issues. -- You are receiving this mail because: You are the assignee for the bug.___ xorg-driver-ati mailing list xorg-driver-ati@lists.x.org https://lists.x.org/mailman/listinfo/xorg-driver-ati

As I said in comment 15, the question is how ppriv->notify_on_damage ends up being TRUE in ms_dirty_update. The only way I can see that being the case is if msRequestSharedPixmapNotifyDamage was called before, but xf86-video-amdgpu doesn't have any code calling the RequestSharedPixmapNotifyDamage hook. > > We really need answers to the questions in comment 27. > > I cannot set up a second machine.

https://bugs.freedesktop.org/show_bug.cgi?id=101998 --- Comment #35 from Meik Neubauer --- (In reply to Michel Dänzer from comment #34) > gdb cannot resolve symbols with only the core dump. Anyway, the screenshots > showed the interesting parts of the backtrace. The problem is I have no clue > how it could end up running the crashing code path. I am not sure I understand this correctly. Maybe I am not getting the point here, because I am not familiar with the intel platform (working on old Mainframes instead), but from what I can get out of gdb is that the call stack is pretty clear and the failure occurs in hw/xfree86/drives/modesetting/driver.c in routine ms_dirty_update where ent->slave_dst->drawable.pScreen-> SharedPixmapNotifyDamage(ent->slave_dst); loads a zero address for the call. The question is, which routine is responsible for setting up the structure in ent->slave_dst->drawable.pScreen and why is that not done correctly. The related data areas seem to be all available in the core dump. I agree that backtracking this is painful bit-counting, but it does not seem out of reach. I would first try to identify the routine that sets up ent->slave_dst->drawable.pScreen I have not tried this yet, because without a complete build setup on my machine this is cumbersome task. I guess that with a ready development environment on your side this is much easier to find out. > We really need answers to the questions in comment 27. I cannot set up a second machine. Due to network security restrictions here I cannot connect between two PCs. And I do not have an external monitor in any other location. So running a remote gdb debugging session is out of reach.

What I could do is reproduce this after login, then suspend the machine and then resume. This produces a similar error and it brings up the Ubuntu error reporting. I took some screenshots of this.

[Bug 101998] X server 1.19.3 failure with amdgpu (radeon M295X) on Ubuntu HWE16.04 kernel 4.10.0-28
https://bugs.freedesktop.org/show_bug.cgi?id=101998 --- Comment #3 from Meik Neubauer --- The Ubuntu HWE16.04 package xserver-xorg-core-hwe-16.04-dbg exists but does not seem to contain any debugging symbols. Installed files: /. /usr /usr/share /usr/share/doc /usr/share/doc/xserver-xorg-core-hwe-16.04-dbg /usr/share/doc/xserver-xorg-core-hwe-16.04-dbg/changelog.Debian.gz /usr/share/doc/xserver-xorg-core-hwe-16.04-dbg/copyright Hence gdb will not debug this. Also: What is the recommended way to safely bring down the existing xserver? I tried 'service lightdm stop' from vt1, but this leaves Xorg and several other X-related processes (xinit, xfailsave) hanging around. Nevertheless, I will attach a dmesg output with the corresponding Xorg.0.log. -- You are receiving this mail because: You are the assignee for the bug.___ xorg-driver-ati mailing list xorg-driver-ati@lists.x.org https://lists.x.org/mailman/listinfo/xorg-driver-ati

https://bugs.freedesktop.org/show_bug.cgi?id=101998 --- Comment #2 from Michel Dänzer --- Please attach the corresponding dmesg output as well. (In reply to Meik Neubauer from comment #0) > [ 120.087] (EE) Backtrace: > [ 120.087] (EE) 0: /usr/lib/xorg/Xorg (xorg_backtrace+0x4e) > [0x55cb016cbf7e] > [ 120.087] (EE) 1: /usr/lib/xorg/Xorg (0x55cb0151a000+0x1b5ce9) > [0x55cb016cfce9] We need to know where in the Xorg code this is located. Make sure the xserver-xorg-core-dbg(sym) package is installed, then try addr2line -i -e /usr/lib/xorg/Xorg 0x55cb016cfce9 If that fails to resolve the source code location, manually start Xorg in gdb and get a backtrace when it crashes. -- You are receiving this mail because: You are the assignee for the bug.___ xorg-driver-ati mailing list xorg-driver-ati@lists.x.org https://lists.x.org/mailman/listinfo/xorg-driver-ati
