Summary: r600g fails to identify the screen refresh rate Product: Mesa Version: git Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: steve@sk2.org

Hi,
With the current git tree (up to 2fe39b46e73aea37152777fe11d489e0b1bc3f92) I'm only getting 10fps running glxgears on my HD4650; other 3D programs exhibit the same problem.
This is an improvement over previous versions of r600g on my system: before 7.10.3 the driver causes constant freezes, and 7.10.3 works but only at 0.8fps (constantly).
I'm attaching the Xorg log and [drm] info from my kernel log. Let me know what other information you need and I'll happily provide it!
Regards,
Stephen

--- Comment #6 from Stephen Kitt steve@sk2.org 2011-08-13 16:06:22 PDT --- I've just figured out what was going on - I noticed after rebooting (to check whether the bug was fixed in 3.0) that the IRQ used by my Radeon card was disabled. It's shared with some of the USB ports and an interrupt arrives before all the drivers have initialised correctly. Reloading the uhci-hcd module re-enables the interrupt and restores full functionality!
