To enable it, open this file, find this line: pi->enable_bapm = false Ĭhange false to true, then compile and install new kernel. It's located in drivers/gpu/drm/radeon/trinity_dpm.c and it's (at the time of writing) enabled only for MSI boards, because of stability issues.
How to enable turbo boost amd a8 series#
turbostatĮDIT: It seems like Trinity series processors have it's own BAPM switch in source. More tests (ran with ondemand scheduler and 3 instances of ffmpeg decoding 1920x1080 H.264 video in background): turbostat]$ sudo cpupower monitorģ| 99,18| 0,82| 1808|| 0,00| 0,00| turbostat]$ sudo. Here is output of cpupower frequency-info, notice Active: no under boost state support: analyzing CPU 0:ĬPUs which run at the same hardware frequency: 0ĬPUs which need to have their frequency coordinated by software: 0Īvailable frequency steps: 1.90 GHz, 1.80 GHz, 1.70 GHz, 1.60 GHz, 1.40 GHzĪvailable cpufreq governors: conservative, ondemand, userspace, powersave, performanceĬurrent policy: frequency should be within 1.90 GHz and 1.90 GHz. Everything works on Windows, however, on Linux CPU frequency can't get past 1.9 GHz (checked with cpufreq-aperf). CPU: K10 (or Husky or K10.I'm using Ubuntu 14.04 (3.13.0-24-generic kernel) on AMD A8-4500m based laptop, and I've recently noticed, that AMD Turbo Core is not working at all.^ OpenGL 4+ compliance requires supporting FP64 shaders and these are emulated on some TeraScale chips using 32-bit hardware.^ These series do not fully comply with OpenGL 2+ as the hardware does not support all types of non-power-of-two (NPOT) textures.^ Radeon 7000 Series has programmable pixel shaders, but do not fully comply with DirectX 8 or Pixel Shader 1.0.Note that this table include micro-architectures not used in the APUs, and a branding series might include older generation chips. The following table shows the graphics and compute APIs support across AMD GPU micro-architectures. Support in this table refers to the most current version. ^ a b DRM ( Direct Rendering Manager) is a component of the Linux kernel.Alternatively active DisplayPort-to-DVI/HDMI/VGA adapters can be employed. ^ To feed more than two displays, the additional panels must have native DisplayPort support.HDCP is mandatory for the output of certain audio formats, placing additional constraints on the multimedia setup. A compatible HDCP display is also needed for this. ^ a b To play protected video content, it also requires card, operating system, driver, and application support.^ Unified shaders : texture mapping units : render output units.^ Single-precision performance is calculated from the base (or boost) core clock speed based on a FMA operation.L1 instruction cache associativity (ways) WBNOINVD, CLWB, RDPID, RDPRU, and MCOMMIT I386, i486, i586, CMOV, NOPL, i686, PAE, NX bit, CMPXCHG16B, AMD-V, RVI, ABM, and 64-bit LAHF/SAHFĪDX, SHA, RDSEED, SMAP, SMEP, XSAVEC, XSAVES, XRSTORS, CLFLUSHOPT, and CLZERO The following table shows features of AMD's APUs
