Atom N270, GPU 945GSE. Running wayland and Enlightenment git. Since mesa 17.2 EFL apps crash on start. Reverting back to 17.1.8 fixes the problem. I don't have mesa build with debug symbols but the problem seems to be in libEGL_mesa.
I've been trying to debug this a little bit. It's worth notin= g that this crash occurs for Apostolos when running weston-simple-egl under weston as well (w= hich removes Enlightenment and EFL from the equation) At one point I thought we'd tracked this to create_wl_buffer() failing beca= use queryImage() on this revision hardware doesn't support __DRI_IMAGE_ATTRIB_FOURCC, and I wrote a patch to test that theory. However recent attempts to debug this against git master seem to indicate that it's= not even getting to create_wl_buffer() before segfaulting anymore. Unfortunately, I don't have the hardware myself, so my ability to help is somewhat limited. It's probably worth noting that the wayland compositor (weston or enlightenment) starts and renders with egl, but clients - including the tri= vial egl demo clients provided with weston crash with a segmentation fault before displaying a single frame.

Created [details] [review]
Patch to recover from failed fourcc query
Ok, this patch has been successfully tested on his hardware an=
d brings
efl/weston apps back to life when applied to 17.2.3.
It will be a couple of days before we can get a re-test against git master
again due to the obstinate user not wanting to deal with an unpackaged drm
dependency. ;)
After testing I'll send the patch to the mailing list for further review.
Dereks patch was tested on 17.2.4 and 17.3.0-rc2 and solves th= e problem. EFL apps and weston-simple-egl work fine. Merge and close.
Send Derek's patch to the list with some ack/rb tags. Modulo a= ny objections I'll push it in a day or two. [1] https://pat= chwork.freedesktop.org/patch/187092/
Oops, I've dropped the ball on this. I need to send it to the list for further review (and potentially revision = in response to that) - will do that today.

Right, my earlier comment should have said s/Send/I've sent/ .= .. Just pushed the patch to master and it will find it's way to 17.2 and 17.3 Thanks for the help gents.
