October 2019 - Linux-kselftest-mirror

by Shuah Khan

Here are the know kselftest issues on Linux 5.4 with top commit commit 619e17cf75dd58905aa67ccd494a6ba5f19d6cc6 on x86_64: The goal is to get these addressed before 5.4 comes out. 3 build failures and status: pidfd - undefined reference to `pthread_create' collect2: error: ld returned 1 exit status Fixed: https://patchwork.kernel.org/patch/11159517/ bfp (two issues) 1. "make TARGETS=bpf kselftest" build fails Makefile:127: tools/build/Makefile.include: No such file or directory This is due to recent kbuild changes and I have a patch ready to send. 2. Related to llvm latest version dependency. This is a hard dependency. Unless users upgrade to latest llvvm, bpf test won't run. The new llvm might not be supported on all distros yet, in which case bpf will not get tested in some rings and on some architectures. gpio "make TARGETS=gpio kselftest" build fails Makefile:23: tools/build/Makefile.include: No such file or directory This is due to recent kbuild changes and I have a patch ready to send. kvm "make TARGETS=kvm kselftest" build fails due --no-pie flags. I am working on a fix for this. no-pie-option defines aren't working correctly and I suspect try-run miht not be defined in this kselftest build case. thanks, -- Shuah

[PATCH bpf-next 0/2] selftest/bpf: remove warns for enable_all_controllers

[PATCH v3] selftests: kvm: Fix libkvm build error

by Shuah Khan

Fix the following build error from "make TARGETS=kvm kselftest": libkvm.a(assert.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIC This error is seen when build is done from the main Makefile using kselftest target. In this case KBUILD_CPPFLAGS and CC_OPTION_CFLAGS are defined. When build is invoked using: "make -C tools/testing/selftests/kvm" KBUILD_CPPFLAGS and CC_OPTION_CFLAGS aren't defined. There is no need to pass in KBUILD_CPPFLAGS and CC_OPTION_CFLAGS for the check to determine if --no-pie is necessary, which is the case when these two aren't defined when "make -C tools/testing/selftests/kvm" runs. Fix it by simplifying the no-pie-option logic. With this change, both build variations work.

[PATCH RESEND] tools: gpio: Use !building_out_of_srctree to determine srctree

by Shuah Khan

make TARGETS=gpio kselftest fails with: Makefile:23: tools/build/Makefile.include: No such file or directory When the gpio tool make is invoked from tools Makefile, srctree is cleared and the current logic check for srctree equals to empty string to determine srctree location from CURDIR. When the build in invoked from selftests/gpio Makefile, the srctree is set to "." and the same logic used for srctree equals to empty is needed to determine srctree. Check building_out_of_srctree undefined as the condition for both cases to fix "make TARGETS=gpio kselftest" build failure.

[PATCH 0/9] Create a userfaultfd demand paging test

by Ben Gardon

When handling page faults for many vCPUs during demand paging, KVM's MMU lock becomes highly contended. This series creates a test with a naive userfaultfd based demand paging implementation to demonstrate that contention. This test serves both as a functional test of userfaultfd and a microbenchmark of demand paging performance with a variable number of vCPUs and memory per vCPU. The test creates N userfaultfd threads, N vCPUs, and a region of memory with M pages per vCPU. The N userfaultfd polling threads are each set up to serve faults on a region of memory corresponding to one of the vCPUs. Each of the vCPUs is then started, and touches each page of its disjoint memory region, sequentially. In response to faults, the userfaultfd threads copy a static buffer into the guest's memory. This creates a worst case for MMU lock contention as we have removed most of the contention between the userfaultfd threads and there is no time required to fetch the contents of guest memory. This test was run successfully on Intel Haswell, Broadwell, and Cascadelake hosts with a variety of vCPU counts and memory sizes. This test was adapted from the dirty_log_test. The series can also be viewed in Gerrit here: https://linux-review.googlesource.com/c/virt/kvm/kvm/+/1464 (Thanks to Dmitry Vyukov <dvyukov(a)google.com> for setting up the Gerrit instance) Ben Gardon (9): KVM: selftests: Create a demand paging test KVM: selftests: Add demand paging content to the demand paging test KVM: selftests: Add memory size parameter to the demand paging test KVM: selftests: Pass args to vCPU instead of using globals KVM: selftests: Support multiple vCPUs in demand paging test KVM: selftests: Time guest demand paging KVM: selftests: Add parameter to _vm_create for memslot 0 base paddr KVM: selftests: Support large VMs in demand paging test Add static flag tools/testing/selftests/kvm/.gitignore | 1 + tools/testing/selftests/kvm/Makefile | 4 +- .../selftests/kvm/demand_paging_test.c | 610 ++++++++++++++++++ tools/testing/selftests/kvm/dirty_log_test.c | 2 +- .../testing/selftests/kvm/include/kvm_util.h | 3 +- tools/testing/selftests/kvm/lib/kvm_util.c | 7 +- 6 files changed, 621 insertions(+), 6 deletions(-) create mode 100644 tools/testing/selftests/kvm/demand_paging_test.c -- 2.23.0.444.g18eeb5a265-goog

[PATCH v2] selftests: kvm: Fix libkvm build error

by Shuah Khan

Fix the following build error from "make TARGETS=kvm kselftest": libkvm.a(assert.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIC This error is seen when build is done from the main Makefile using kselftest target. In this case KBUILD_CPPFLAGS and CC_OPTION_CFLAGS are defined. When build is invoked using: "make -C tools/testing/selftests/kvm" KBUILD_CPPFLAGS and CC_OPTION_CFLAGS aren't defined. There is no need to pass in KBUILD_CPPFLAGS and CC_OPTION_CFLAGS for the check to determine if --no-pie is necessary1s, which is the when these two aren't defined when "make -C tools/testing/selftests/kvm" runs. Fix it by simplifying the no-pie-option logic. With this change, bith build variations work.
