GPU Memory Usage Information¶
Various memory accounting can be accessed via sysfs
mem_info_vram_total¶
The amdgpu driver provides a sysfs API for reporting current total VRAM available on the device The file mem_info_vram_total is used for this and returns the total amount of VRAM in bytes
mem_info_vram_used¶
The amdgpu driver provides a sysfs API for reporting current total VRAM available on the device The file mem_info_vram_used is used for this and returns the total amount of currently used VRAM in bytes
mem_info_vis_vram_total¶
The amdgpu driver provides a sysfs API for reporting current total visible VRAM available on the device The file mem_info_vis_vram_total is used for this and returns the total amount of visible VRAM in bytes
mem_info_vis_vram_used¶
The amdgpu driver provides a sysfs API for reporting current total of used visible VRAM The file mem_info_vis_vram_used is used for this and returns the total amount of currently used visible VRAM in bytes
mem_info_gtt_total¶
The amdgpu driver provides a sysfs API for reporting current total size of the GTT. The file mem_info_gtt_total is used for this, and returns the total size of the GTT block, in bytes
mem_info_gtt_used¶
The amdgpu driver provides a sysfs API for reporting current total amount of used GTT. The file mem_info_gtt_used is used for this, and returns the current used size of the GTT block, in bytes
PCIe Accounting Information¶
pcie_bw¶
The amdgpu driver provides a sysfs API for estimating how much data has been received and sent by the GPU in the last second through PCIe. The file pcie_bw is used for this. The Perf counters count the number of received and sent messages and return those values, as well as the maximum payload size of a PCIe packet (mps). Note that it is not possible to easily and quickly obtain the size of each packet transmitted, so we output the max payload size (mps) to allow for quick estimation of the PCIe bandwidth usage
pcie_replay_count¶
The amdgpu driver provides a sysfs API for reporting the total number of PCIe replays (NAKs) The file pcie_replay_count is used for this and returns the total number of replays as a sum of the NAKs generated and NAKs received
GPU SmartShift Information¶
GPU SmartShift information via sysfs
smartshift_apu_power¶
The amdgpu driver provides a sysfs API for reporting APU power shift in percentage if platform supports smartshift. Value 0 means that there is no powershift and values between [1-100] means that the power is shifted to APU, the percentage of boost is with respect to APU power limit on the platform.
smartshift_dgpu_power¶
The amdgpu driver provides a sysfs API for reporting dGPU power shift in percentage if platform supports smartshift. Value 0 means that there is no powershift and values between [1-100] means that the power is shifted to dGPU, the percentage of boost is with respect to dGPU power limit on the platform.
smartshift_bias¶
The amdgpu driver provides a sysfs API for reporting the smartshift(SS2.0) bias level. The value ranges from -100 to 100 and the default is 0. -100 sets maximum preference to APU and 100 sets max perference to dGPU.
