reports.

Largest Free Block (lfb) is a statistic about the memory allocator. It refers to the largest contiguous block of physical memory that can be allocated: at most, 4 MB. It can become smaller with memory fragmentation. The physical allocations in virtual memory can be bigger. |
Amount of RAM in use in MB. |
Total amount of RAM available for applications. |
Z is the size of the largest free block, N the number of free blocks of this size. |
or
X and Y are rough approximations based on time spent in the system idle
process as reported by the Linux kernel in |
Load statistics for each of the CPU cores relative to the current running frequency Z, or 'off' in case a core is currently powered down. |
Load statistics for each of the CPU cores relative to the current running frequency Z, or 'off' in case a core is currently powered down. |
CPU frequency in megahertz. Goes up or down dynamically depending on the CPU workload. |
GR3D is the iGPU engine. |
Percent of the GR3D that is being used, relative to the current running frequency. Aggregated between GPC0 and GPC1. |
GR3D frequency in megahertz for each available GPC (that is, GPC0, GPC1, and so on.) |

NVENC is NVIDIA video encoder. NVENC1 is the second instance of NVENC. NVENC1 may be reported if it is present and enabled. |
Load stats is added. If both frequency and load are enabled, the output looks like NVENC X%@Y. If only frequency is enabled: NVENC_FREQ @Y. If only load: NVENC_LOAD X%. |

NVDEC is NVIDIA video encoder. NVDEC1 is the second instance of NVDEC. NVDEC1 may be reported if it is present and enabled. |
Load stats is added. If both frequency and load are enabled, the output looks like NVDEC X%@Y. If only frequency is enabled: NVDEC_FREQ @Y. If only load: NVDEC_LOAD X%. |

VIC is the video image compositor. |
Load stats is added. If both frequency and load are enabled, the output looks like VIC X%@Y. If only frequency is enabled: VIC_FREQ @Y. If only load: VIC_LOAD X%. |
VIC frequency in megahertz |

NVDLA is NVIDIA deep learning accelerator. NVDLA1 is the second instance of NVDEC. NVDLA1 may be reported if it is present and enabled. |
Load stats is added. If both frequency and load are enabled, the output looks like NVDLA0 X%@Y. If only frequency is enabled: NVDLA0_FREQ @Y. If only load: NVDLA0_LOAD X%. | NVDLA frequency in megahertz | N/A |
PVA is the programmable vision accelerator and VPU is the vector processing unit.PVA0_VPU1 is the second instance of the VPU for PVA0. |
