Move to kernel version 5.10 using source from the Yocto Project. 1. Add STX patches for kernel 5.10. 2. Support git source for linux-yocto. 3. Add build_srpm from build-tools/default_build_srpm and modified for git repo from yocto 4. Modify std and rt config files. 5. Build python-perf instead of python3-perf for std kernel. python-perf is needed by tuned-2.8.0-5.el7.noarch. 6. Modify rt spec to build out package kernel-rt-tools and kernel-rt-kvm. 7. Add kernel-5.10.30-x86_64-rt.config.tis_extra and kernel-5.10.30-x86_64.config.tis_extra 8. Add a dist field to avoid undesired rebuilds. 9. Ensure -unsigned package is populated Story: 2008921 Partial-Task: 42519 Signed-off-by: Jackie Huang <jackie.huang@windriver.com> Signed-off-by: Vefa Bicakci <vefa.bicakci@windriver.com> Signed-off-by: Jiping Ma <jiping.ma2@windriver.com> Change-Id: Id1f635302f265826f7ff2860a3bed4b7755b2888

Subject: [PATCH 09/10] restrict iSCSI kthreads to CPUs in cpu_kthread_mask
|
|
|

Do not allow them to run on other CPUs to prevent interference with VMs.
