Hi all, I'm using haswell with linux-3.8.13.4: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=commitdiff;h=d1baa1360260b5a01938674fc518109a4e5a148d and I find the CAGF showed by i915_cur_delayinfo is always twice as gt_cur_freq_mhz, e.g., when the system is idle, I can get the below log: ----------------------------- Log begins # cat /sys/kernel/debug/dri/0/i915_cur_delayinfo; echo; cat /sys/devices/pci0000:00/0000:00:02.0/drm/card0/gt_cur_freq_mhz; echo ; GT_PERF_STATUS: 0x00000800 RPSTAT1: 0x00040400 Render p-state ratio: 8 Render p-state VID: 0 Render p-state limit: 255 CAGF: 400MHz RP CUR UP EI: 55890us RP CUR UP: 276us RP PREV UP: 0us RP CUR DOWN EI: 94295us RP CUR DOWN: 389us RP PREV DOWN: 0us Lowest (RPN) frequency: 200MHz Nominal (RP1) frequency: 400MHz Max non-overclocked (RP0) frequency: 1200MHz 200 ----------------------------- Log ends. But with the latest 3.10.0, both values are 200, as expected. I guess there is a fix in 3.10.0 I can pick for my 3.8.13.4?
