Quality expectations
| Platform | Quality | OpenCL | Level Zero | WSL |
|---|---|---|---|---|
| DG1 | Production | 3.0 | 1.3 | Yes |
| DG2 | * | 3.0 | 1.3 | Yes |
| Skylake | Production | 3.0 | 1.3 | -- |
| Kaby Lake | Production | 3.0 | 1.3 | -- |
| Coffee Lake | Production | 3.0 | 1.3 | Yes |
| Ice Lake | Production | 3.0 | 1.3 | Yes |
| Tiger Lake | Production | 3.0 | 1.3 | Yes |
| Rocket Lake | Production | 3.0 | 1.3 | -- |
| Alder Lake | Production | 3.0 | 1.3 | Yes |
| Elkhart Lake | Production | 3.0 | -- | Yes |
| Broadwell | Maintenance | 3.0 | -- | -- |
| Apollo Lake | Maintenance | 3.0 | -- | -- |
| Gemini Lake | Maintenance | 3.0 | -- | -- |
All platforms were validated on Ubuntu 22.04 LTS with stock kernel, unless noted otherwise.
- Elkhart Lake was tested on Ubuntu 20.04 LTS with stock kernel v.5.8.5
- DG1 was tested with drm-tip kernel v.6.1.0-rc1
WSL support was tested with Windows host driver 101.3959 (DG2), or 101.3790 and 101.2114 (all other platforms)
* DG2 is at production quality, when combined with an out-of-tree kernel mode driver distributed separately.
Quality levels
- Experimental - no quality expectations
- Early support - platform may not be available on the market yet
- Pre-Release - suitable for integration and testing, gathering customer feedback
- Beta - suitable for integration and broad testing
- Production - Beta + meets API-specific conformance requirements; suitable for production
- Maintenance - Reduced test frequency compared to Production, no longer recommended for new deployments. Reactive support for customers.
Additional information
- To maintain better Runtime-Compiler compatibility, Intel changed default graphics compute binary format to new portable ELF based ZE Binary format. Legacy patch-token based approach required JIT recompilations to maintain compatibility in case of interface changes, leading to longer application start up time.
- Existing legacy binaries will be supported by OpenCL and Level Zero GPU runtimes by end of 2023.
- To ensure smooth transition to new format ‘-ze-disable-zebin’/’-cl-disable-zebin’ graphics backend options are provided to fallback to legacy binary format for either offline or online compilation. New ZE Binary format is generated by default
Examples to disable zebin (force legacy binary):
AOT: ocloc –options –cl-disable-zebin; cmc -binary-format=ocl; dpcpp test.cpp -fsycl -fsycl-targets=spir64_gen,spir64 -Xs '-options -ze-disable-zebin'
JIT: dpcpp test.cpp -fsycl -Xs '-options -ze-disable-zebin' - Legacy format support by OpenCL and Level Zero GPU runtimes will be deprecated starting 2024.
- Intel encourages ISVs/OEMs/ODMs to adjust plans accordingly
- packages were built with custom flag NEO_ENABLE_i915_PRELIM_DETECTION=1
