## What it does

This skill edits the per-board nvpmodel configuration for Jetson/Tegra targets based on T234 Orin and T264 Thor. It can add or remove power profiles, change CPU, GPU, EMC, and TPC clamps, and set the profile used by default at boot.

The file format uses PARAM, POWER_MODEL, and PM_CONFIG blocks. Clock values should come from the kernel’s available_frequencies table, while parameter names should be copied from an existing POWER_MODEL because chip families use different conventions. CORE_0 must remain online.

Edits go to the overlay copy under `<source.root_path>`; `<bsp_image.root_path>` is read-only. Check the active profile, its `bsp_image` block, and the `Linux_for_Tegra/` directories first, because missing prerequisites route the task to other Jetson commands.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-customize-nvpmodel -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/jetson-customize-nvpmodel/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/jetson-customize-nvpmodel/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-customize-nvpmodel -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/jetson-customize-nvpmodel/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-customize-nvpmodel -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/jetson-customize-nvpmodel/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install NVIDIA/skills jetson-customize-nvpmodel
```

2. **Manually: put the files in place**
- File: `.github/skills/jetson-customize-nvpmodel/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-customize-nvpmodel -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/NVIDIA/skills --path skills/jetson-customize-nvpmodel
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/jetson-customize-nvpmodel/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-customize-nvpmodel -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/NVIDIA/skills/tree/HEAD/skills/jetson-customize-nvpmodel/SKILL.md

## When to use it
- add an nvpmodel power profile
- remove an obsolete mode from the config
- change CPU, GPU, EMC, or TPC frequency caps
- set the boot default power mode
- keep a board configuration aligned with its related profiles

## Example prompts
- Edit the nvpmodel power profile for the active Jetson target and add a new mode.
- Update the CPU and GPU caps in `nvpmodel_<active-sku>.conf` using values from `available_frequencies`.
- Set the profile with ID 2 as the boot default and validate the configuration.

# Modify nvpmodel Power Mode (BSP-side)

## Purpose

Edit the per-board nvpmodel configuration so the device boots with
the desired power-mode set, CPU/GPU/EMC/TPC clamps, and default
mode. BSP-side only — all writes land in the overlay tracker, the
upstream `bsp_image` copy is read-only.

This skill handles BSP-side edits to the per-board nvpmodel configuration file: adding modes, removing modes, editing CPU/GPU/EMC/TPC clamps, and changing the boot default. Applies on Jetson / Tegra platforms (T234 Orin, T264 Thor).

## File format (canonical, per the BSP file header)

```
# 1. PARAM definitions — declare named knobs and their sysfs paths
< PARAM TYPE=FILE  NAME=<param_name> >
<arg_name> </absolute/sysfs/path>
...
< PARAM TYPE=CLOCK NAME=<param_name> >
FREQ_TABLE        </sysfs/.../available_frequencies>
MAX_FREQ          </sysfs/.../max_freq>
MIN_FREQ          </sysfs/.../min_freq>
FREQ_TABLE_KNEXT  </sysfs/.../available_frequencies>     # kernel-NEXT variant
MAX_FREQ_KNEXT    </sysfs/.../max_freq>
MIN_FREQ_KNEXT    </sysfs/.../min_freq>

# 2. POWER_MODEL definitions — one block per profile
< POWER_MODEL ID=<int> NAME=<string> >
PARAM_NAME ARG_NAME <value>
...

# 3. PM_CONFIG — mandatory; selects boot default
< PM_CONFIG DEFAULT=<id> >
```

Rules:

- For `TYPE=FILE`, `<value>` is a **string** (`0`, `1`, `on`, `auto`, …).
- For `TYPE=CLOCK`, `<value>` is an **integer** (Hz for clocks, raw integer for masks).
- `-1` for a CLOCK value means **INT_MAX** (no cap).
- The header `< … >` line must start at column 0 with a space after `<` and before `>`. Strict.
- Every `PARAM_NAME` referenced in a POWER_MODEL must already be declared above.
- **Frequency values must come from the kernel's `available_frequencies`** table for that clock — values not in the table get silently rounded.
- `CORE_0` cannot be offlined; at least one CPU core must remain online in every profile.
- **Copy PARAM names verbatim** from an existing POWER_MODEL block in the per-board file — chip families differ (T234 Orin uses `CPU_A78_<n>` for CPU clusters; T264 Thor uses a different convention). Don't invent.

## Prerequisites

Resolve the active profile per
[`../../context/target-platform-contract.md`](../../context/target-platform-contract.md).
Refuse and route in these cases:

| Condition | Refuse with |
|---|---|
| No active profile, or `active: NA` | Route to `/jetson-set-target` or `/jetson-init-target`. |
