Comment 1 Eric Anholt 2008-02-15 12:34:14 UTC

Not 64-bit related.  Easily encountered on 32-bit as well.

It looks like this is an issue with shared objects between contexts.  We need to move the bufmgr back to the screen.

Comment 5 Eric Anholt 2008-04-30 11:10:12 UTC

Thank you for reporting the many manywin issues in separate reports, but in this case they do happen to be the same cause (bufmgr needs to be in the screen, not the context).

Comment 6 Gordon Jin 2008-06-11 22:59:36 UTC

This is still reproducible with the latest mesa master.

This issue still exist with git tip

Comment 9 lin, jiewen 2008-09-22 00:13:49 UTC

This still exists in mesa-7.2 release.

Comment 11 haihao 2008-09-22 18:19:43 UTC

  The problem is that a BO is created with one bufmgr, then it is cached and used        for another bufmgr. I think moving the bufmgr back to the screen can't fix this     issue. Mesa master, intel-2008-q3 branch (which have moved the bufmgr back to screen) all have this similar issue.

Comment 12 liuhaien 2008-09-25 02:32:11 UTC

This still exists with gem-classic.

Comment 13 zhao jian 2008-09-25 02:39:13 UTC

I tested it with mesa intel-2008-q3 branch on gm45,and it still fails, but with different error messages as following:

The error message should be : 
manywin: intel_bufmgr_fake.c:748: intel_bufmgr_fake_contended_lock_take: Assertion `((&bufmgr_fake->on_hardware)->next == (&bufmgr_fake->on_hardware))' failed.

sorry for the mistake!

Comment 15 Gordon Jin 2008-09-25 04:19:40 UTC

Eric, so this happens on both mesa-7.2 and intel-2008-q3.

Comment 16 Eric Anholt 2008-10-09 13:17:28 UTC

haihao was right -- even with bufmgr in the screen (where it needs to be), this demo opens multiple X11 Displays and tries to use GL on each, resulting in multiple bufmgr instances when multiple screeninits are called in the driver.  Mesa's driver API doesn't seem to give us any driver storage across the whole program, not just a single X11 Display, and I'm not sure that it really should.

Real programs shouldn't be doing this, so I'm removing it from the blocker list.

There are 2 bugs with real programs marked as dup with this bug. Are they true dups?
-- 15584: qt4 demo
-- 17583: xgl

Comment 18 Eric Anholt 2008-10-10 13:32:47 UTC

#15584 works fine at least.

Comment 19 liuhaien 2008-10-21 19:05:33 UTC

this issue also happens with our q3-rc5 package on q45 .

Comment 20 Gordon Jin 2008-10-28 02:13:47 UTC

This bug doesn't exist with GEM kernel. So let's track manywin issue at bug#18262 (GEM bug).
