[gentoo-dev] [PATCH 0/2] rocm.eclass for ROCm packages written in HIP

[gentoo-dev] [PATCH 0/2] rocm.eclass for ROCm packages written in HIP

[Yiyang Wu]

This eclass provides utilities for ROCm libraries in
https://github.com/ROCmSoftwarePlatform, e.g. rocBLAS, rocFFT.
It contains a USE_EXPAND, amdgpu_targets_*, which handles the GPU
architecture to compile, and keep targets coherent among dependencies.
Packages that depend on ROCm libraries, like cupy, can also make use of
this eclass, mainly specify GPU architecture and it's corresponding
dependencies via USE_EXPAND.

This is the core delivery in GSoC 2022 project "Refining ROCm Packages
in Gentoo"

+# @BLURB: Common functions and variables for ROCm packages written in HIP
+# @DESCRIPTION:
+# ROCm packages such as sci-libs/<roc|hip>* can utilize functions in this eclass.
+# Currently, it handles the AMDGPU_TARGETS variable via USE_EXPAND, so user can
+# use USE flag to control which GPU architecture to compile, and ensure coherence
+# among dependencies. It also specify CXX=hipcc, to let hipcc compile. Another
+# important function is src_test, which checks whether a valid KFD device exists
+# for testing, and then execute the test program.
+#
+# Most ROCm packages use cmake as build system, so this eclass does not export
+# phase functions which overwrites the phase functions in cmake.eclass. Ebuild
+# should explicitly call rocm_src_* in src_configure and src_test.
+# 
+# @EXAMPLE:
+# # Example for ROCm packages in https://github.com/ROCmSoftwarePlatform
+# inherit cmake rocm
+# SRC_URI="https://github.com/ROCmSoftwarePlatform/${PN}/archive/rocm-${PV}.tar.gz -> ${P}.tar.gz"

+# IUSE="test"
+# REQUIRED_USE="${ROCM_REQUIRED_USE}"
+# RESTRICT="!test? ( test )"

+#     )
+#     rocm_src_configure
+# }
+# 
+# src_test() {
+#     rocm_src_test
+# }
+# 
+# # Example for packages depend on ROCm libraries -- a package depend on
+# # rocBLAS, and use comma seperated ${HCC_AMDGPU_TARGET} to determine GPU

We no longer distinguished between too old and unknown. Modern style
