+
+Intel OpenCL implementation for IvyBridge & Haswell iGPUs.
+
+## Description
+
+Beignet is an open source OpenCL implementation for Intel Gen7/Gen7.5 GPUs (IvyBridge, Haswell). This package builds from git master with LLVM 7.0.
+
+**Supported Hardware:**
+- Intel HD Graphics 4000/4200/4400/4600 (Haswell)
+- Intel HD Graphics 2500/4000 (IvyBridge)
+
+## Installation
+
+```bash
+# Install all dependencies (builds llvm70 and clang70 first)
+lure install beignet-git
+```
+
+## Verification
+
+```bash
+clinfo | grep -i "Intel Gen"
+```
+
+Expected output:
+```
+Platform Name                                   Intel Gen OCL Driver
+Device Name                                     Intel(R) HD Graphics Haswell ...
+```
+
+## Dependencies
+
+- **clang70** - Clang 7.0.1 (automatically pulls in llvm70)
+- ocl-icd-libopencl1, libgl1, libdrm2
+
+## Why LLVM 7.0?
+
+Beignet was abandoned by Intel and only supports LLVM 3.9-7.0. Modern LLVM versions have incompatible API changes. This package uses a self-contained LLVM 7.0 installation in `/opt/llvm70/`.
+
+## Alternatives
+
+- **rusticl** (Mesa 24.0+) - Modern OpenCL for Intel GPUs, actively maintained
+- **intel-compute-runtime** - For newer Intel GPUs (Broadwell+)

+# clinfo-git
+
+LURE package for clinfo - OpenCL platform and device information tool.
+
+## Description
+
+clinfo prints all known information about all available OpenCL platforms and devices in the system.
+
+## Dependencies
+
+- Build: `git`, `build-essential`, `opencl-headers`, `ocl-icd-opencl-dev`
+- Runtime: `ocl-icd-libopencl1`
+
+## Installation
+
+```bash
+lure build
+sudo apt install ./clinfo-git_*.deb
+```
+
+## Usage
+
+```bash
+clinfo           # List all OpenCL platforms and devices
+clinfo -l        # Short listing
+clinfo --json    # JSON output
+```
+
+## Lessons Learned
+
+1. **Version function**: The AUR PKGBUILD uses `git describe --long --tags` which may fail if no tags exist. Added fallback to commit-based versioning.
+
+2. **Bash local variables**: LURE's shell may not support `local` keyword in all contexts. The warning `local: can only be used in a function` appears but doesn't affect the build.
+
+## Notes
+
+This is a generic OpenCL tool that works with any OpenCL implementation (VC4CL, POCL, Mesa Clover, etc.).

+## Description
+
+This package provides LLVM 7.0.1, an older but stable version required by [beignet](https://github.com/intel/beignet) for Intel IvyBridge/Haswell OpenCL support. Modern LLVM versions (11+) are incompatible with beignet due to API changes.
+
+## Installation
+
+```bash
+lure install llvm70
+```
+
+## Build Dependencies
+
+- cmake, ninja-build, libffi-dev, libedit-dev, libncurses-dev, libxml2-dev, binutils-dev
+
+## Files
+
+Installs to `/opt/llvm70/` to avoid conflicts with system LLVM.
+
+## Related Packages
+
+- **clang70** - Clang 7.0.1 frontend (requires this package)
+- **beignet-git** - Intel OpenCL driver (requires clang70)
