Looking in debugfs, there's a whole load of BOs that are listed as "active", yet the GPU is idle: 00020000: A 0 ( 7) 00000000 00000000 8294400 00010000: I 0 ( 1) 00000000 00000000 4096 00010000: I 0 ( 1) 00000000 00000000 4096 00010000: I 0 ( 1) 00000000 00000000 327680 00010000: A 0 ( 7) 00000000 00000000 8388608 00010000: I 0 ( 1) 00000000 00000000 8388608 00010000: I 0 ( 1) 00000000 00000000 8388608 00010000: A 0 ( 7) 00000000 00000000 8388608 00010000: A 0 ( 3) 00000000 00000000 8388608 00010000: A 0 ( 4) 00000000 00000000 8388608 00010000: A 0 ( 3) 00000000 00000000 8388608 00010000: A 0 ( 3) 00000000 00000000 8388608 00010000: A 0 ( 3) 00000000 00000000 8388608 .... 00010000: A 0 ( 3) 00000000 00000000 8388608 Total 38 objects, 293842944 bytes My guess is there's something up with the way a job completes that's causing the BOs not to be marked inactive. I haven't yet been able to debug any further. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
