Make sure your have the rlc firmware loaded as it's required for the interrupt controller to work. Check your dmesg. It should show something like: [drm] Connector 1: [drm] HDMI-A [drm] HPD2 [drm] DDC: 0x6440 0x6440 0x6444 0x6444 0x6448 0x6448 0x644c 0x644c [drm] Encoders: [drm] DFP1: INTERNAL_UNIPHY In this case HPD2 has been (in theory) wired to the hdmi port. Plug/unplug in your hdmi port and check if bit 1 of any of the DC_HPDx_INT_STATUS regs changes when you connect/disconnect the monitor. #define DC_HPD1_INT_STATUS 0x7d00 #define DC_HPD2_INT_STATUS 0x7d0c #define DC_HPD3_INT_STATUS 0x7d18 #define DC_HPD4_INT_STATUS 0x7d24 #define DC_HPD5_INT_STATUS 0x7dc0 #define DC_HPD6_INT_STATUS 0x7df4 You can use radeonreg: http://cgit.freedesktop.org/~airlied/radeontool/ to dump registers. E.g. (as root), ./radeonreg regmatch 0x7d00 -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
