description |
My initial bugreport was here: https://bugs.freedesktop.org/show_bug.cgi?id=71116
- Recompiling libdrm with gcc 4.7 fixed the bug.
Upstream GCC mail thread here: http://gcc.gnu.org/ml/gcc-help/2013-07/msg00103.html
This was fixed thanks to Emil Velikov from the nouveau project. |
[Impact]
* Relocations on nv04-nv4f are completely broken, any kind of memory stress will result in userspace failure.
[Test Case]
* Suspend on a system with an affected nvidia card.
* Resume should complete without any errors in FIFO.
* Other test is to run max-texture-size from piglit, system should survive.
* For m-a same change: confirm libdrm-dev:amd64 and libdrm-dev:i386 coinstall.
[Regression Potential]
* Original bug report was caused by undefined behavior in gcc:
- *push->cur++ = pushbuf_krel(push)
- pushbuf_krel uses (push->cur - push->bgn) to calculate offset.
- It's undefined whether push->cur is incremented before calling pushbuf_krel or not.
- New gcc changed the order, causing the bug.
- Fixed by calling push->cur++ in a separate statement.
* Bug reports will be watched for any new problems that may pop up.
