When I enable the dri module on my system the performance of the X
server becomes completely unacceptable - things slow to the point where
I can see individual things being rendered and there can be delays of
many seconds before keypresses are responded to.  The CPU usage of the
server goes through the roof.  Without DRI performance is completely
acceptable.

Looking at the server log everything seems normal during startup but
there is a profusion of "(EE) R128(0): Idle timed out, resetting
engine..." messages towards the end of the log.  A full copy of the log
for a failed startup is below, along with one from my current startup
where performance is fine.

retitle 249277 xserver-xfree86: [ati/r128] DRI performance terrible, log fills with '(EE) R128(0): Idle timed out, resetting engine...' on Rage 128 PF/PRO AGP 4x TMDS rev 0
tag 249277 + moreinfo upstream
thanks

There is reason to believe that the proposed fix for #236187 will fix
this problem as well.

Are you interested in building XFree86 from source yourself and letting
us know?

Unfortunately, this seems to make things worse rather than better
(assuming I didn't stuff up the module build, which is possible).
Previously everything was just extremely slow but now the GDM login
dialog does not appear - I'm left sitting watching the default server
background with a watch cursor.

The rest of the system appears fine - there's no responsiveness problems
with SSH or anything.

I've attached the X server log.

[I see nothing unusual in the log.]

Hmm, this is disappointing to hear.  Well, I'm going to go ahead and
apply the patch anyway, and then we will subject ATI Rage 128 users to
the SVN trunk for a few days before letting the patch go into a release.

Hi Mark,

About 3 years ago, you reported a bug to the Debian BTS regarding
terrible DRI performance on a ATI Rage 128 Pro board.
Did you reproduce this problem recently? If not, I will close this bug
in the next weeks.

Thanks,
Brice

I haven't tried recently.  I could try if you're likely to look at it?

There have been lots of improvement in the DRI on ATI boards. I'd expect
it to work very well now. So if you happen to have some time to try
again, that'd be nice, thanks.

Hi Mark,

Did you have a chance to try to reproduce this bug?

Thanks,
Brice

Not yet.  I have the machine but need to go and buy a keyboard for it
before I can do anything constructive with it.

Hi Mark,

any news on this bug?  I'm trying to close or reassign bugs filed
against xserver-xfree86 before removing the package from unstable.

Cheers,
Julien

Not yet, sorry.  I still haven't bought an extra keyboard.

Should this bug be closed or reassigned to xserver-xorg?

Kind regards,
Andrei
