Subject: [PATCH 0/1] Enable GNU make parallel jobs by default for GCC5 and CLANGPDB ToolChains
Date: Mon, 17 Jan 2022 22:42:50 +0800 [thread overview]
Message-ID: <20220117144251.1087-1-steven.shi@intel.com> (raw)
The GNU make parallel jobs flgs (-j or --jobs) can significantly (~30%) improve the edk2 build time in Linux.
This patch enable the GNU make parallel jobs by default.
Below the OVMF test result on GCC5 and CLANGPDB toolchains:
GCC5 build without patch:
jshi19@ub2-uefi-b01:~/wksp_efi/edk2-2$ time build -p OvmfPkg/OvmfPkgIa32X64.dsc -a IA32 -a X64 -t GCC5 -DSECURE_BOOT_ENABLE=TRUE
real 0m58.784s
user 5m18.820s
sys 0m46.337s
GCC5 build with patch:
jshi19@ub2-uefi-b01:~/wksp_efi/edk2-2$ time build -p OvmfPkg/OvmfPkgIa32X64.dsc -a IA32 -a X64 -t GCC5 -DSECURE_BOOT_ENABLE=TRUE
real 0m41.547s
user 5m23.617s
sys 0m47.397s
GCC5 build time improved by +29%
CLANGPDB build without patch:
jshi19@ub2-uefi-b01:~/wksp_efi/edk2-2$ time build -p OvmfPkg/OvmfPkgIa32X64.dsc -a IA32 -a X64 -t CLANGPDB -DSECURE_BOOT_ENABLE=TRUE

CLANGPDB build with patch:
jshi19@ub2-uefi-b01:~/wksp_efi/edk2-2$ time build -p OvmfPkg/OvmfPkgIa32X64.dsc -a IA32 -a X64 -t CLANGPDB -DSECURE_BOOT_ENABLE=TRUE
real 0m31.307s
user 4m21.952s
sys 0m30.641s
CLANGPDB build time improved by +51%
