Description markus gapp 2015-09-04 15:41:27 UTC

Hi

On a Gentoo System I experience repeated random segfaults of mostly kde x11 applications and xorg freezes since updrading mesa from 10.x.y to 11.0.0_rc[12].

mesa was compiled with (gentoo use flags): classic dri3 egl gallium gbm gles1 gles2 nptl osmesa udev xa xvmc

llvm was compiled with (gentoo use flags): clang libffi ncurses python static-analyzer xml

llvm 3.7.0 & 3.6.2 (no difference)
kernel 4.2.0 & 4.1.6 (no difference)
librm 2.6.64

xorg log is silent.

dmesg says:

Comment 2 Alex Deucher 2015-09-04 15:48:59 UTC

r600 does not use llvm for graphics so that doesn't matter.  What version of 10.x was working?  Can you bisect?

git bisect found commit 29aaab2b5f55cc6d9a84f58ce2bb8607e76a9dde as the culprit. reverting it makes 11.0.0-rc2 work on my hw. for some reason it does not like

    winsys/radeon: align BO size to page size
    
    This is the basic granularity for BO allocations. The alignment also
    helps with BO reuse by the cached bufmgr.
    
    This results in a huge 45% speedup in Metro 2033 Redux on my test
    system. The game relies on buffer orphaning with very small buffers
    (hundreds of bytes in size) and that did not work efficiently
    before. This change may also affect other applications and games.
