+Usage
+-----
+
+1. Check the Linux Kernel Module (driver) for Intel GPU:
+
+      lsmod | grep -i xe
+
+   For desktop distros with rolling-ish kernel updates, xe is usually included already.
+
+2. Search and install `intel-compute-runtime` (or similar) with your host OS' package manager.
+   If not found, just ignore it and run directly.
+
+   For Ubuntu, follow this instruction and install the compute-related packages:
+       https://dgpu-docs.intel.com/driver/client/overview.html
+
+3. Run the container:
+
+====
+mkdir -p \
+  storage \
+  storage-models/models \
+  storage-models/hf-hub \
+  storage-models/torch-hub \
+  storage-user/input \
+  storage-user/output \
+  storage-user/workflows
+
+podman run -it --rm \
+  --name comfyui-xpu \
+  --device=/dev/dri \
+  --ipc=host \
+  --security-opt label=disable \
+  -p 8188:8188 \
+  -v "$(pwd)"/storage:/root \

+  -v "$(pwd)"/storage-models/torch-hub:/root/.cache/torch/hub \
+  -v "$(pwd)"/storage-user/input:/root/ComfyUI/input \
+  -v "$(pwd)"/storage-user/output:/root/ComfyUI/output \
+  -v "$(pwd)"/storage-user/workflows:/root/ComfyUI/user/default/workflows \
+  -e CLI_ARGS="--disable-smart-memory --async-offload" \
+  yanwk/comfyui-boot:xpu
+====
+
+Note:
+
+1. "--disable-smart-memory" is useful for XPU, although it consumes more RAM.
+2. "--async-offload" gives subtle improvement and no visible harm.
+
+More CLI_ARGS:
+
+--lowvram
+--bf16-unet
+--bf16-vae
+--bf16-text-enc
+--mmap-torch-files
+--reserve-vram 1
+
+Check the doc before use:

+Test result on Arc B580
+-----------------------
+
+Time on generating one 1024x1024px image (pre-warmed, only infer time)
+
+* SD 1.5 (20-step): OK (5s) | 512x512: GOOD (1s)
+* SDXL (28-step): OK (6s)
+* SDXL Refiner (20+5-step): OK (4+1s)
+* Stable Cascade (20+10-step): FAST (3+3s)
+* SD 3.5 large fp8 (20-step): GOOD (26s)
+* Flux1 schnell (4-step): GOOD (8s)
+* Flux1 dev fp8 (20-step): GOOD (35s)
+* Flux1 Krea dev (20-step): OK (46s)
+
+* Hunyuan3D 2.0 (Comfy Repackaged): 'Non-uniform work-groups are not supported by the target device'
+* StableZero123: 'Non-uniform work-groups are not supported by the target device'
+
+* Wan 2.2 5B Text to Video (640x352, 121 frames): FAST (60s, very poor quality)
+* Wan 2.2 5B Text to Video (960x544, 121 frames): OK (181s, low quality)
+* Wan 2.2 5B Text to Video (1280x704, 121 frames): FAILED (OOM)
+
+
+Notes
+--------------
+
+1. Once OOM, ComfyUI won't crash, but GPU will stop responding
+   for future prompt (UR_RESULT_ERROR_DEVICE_LOST).
+   In that case, you will need to restart ComfyUI.
+
+2. IPEX (Intel Extension for PyTorch) is not included, as most of its features
+   have been merged upstream and it is being phased out:
+   https://github.com/intel/intel-extension-for-pytorch/releases
+
+
+For Windows Users
+-----------------
+
+Just use Intel AI Playground:
