selftests: fix kvm relocatable native/cross builds and installs

2020-05-27T15:48:09Z

[ Upstream commit 66d69e081b526b6a6031f0d3ca8ddff71e5707a5 ] kvm test Makefile doesn't fully support cross-builds and installs. UNAME_M = $(shell uname -m) variable is used to define the target programs and libraries to be built from arch specific sources in sub-directories. For cross-builds to work, UNAME_M has to map to ARCH and arch specific directories and targets in this Makefile. UNAME_M variable to used to run the compiles pointing to the right arch directories and build the right targets for these supported architectures. TEST_GEN_PROGS and LIBKVM are set using UNAME_M variable. LINUX_TOOL_ARCH_INCLUDE is set using ARCH variable. x86_64 targets are named to include x86_64 as a suffix and directories for includes are in x86_64 sub-directory. s390x and aarch64 follow the same convention. "uname -m" doesn't result in the correct mapping for s390x and aarch64. Fix it to set UNAME_M correctly for s390x and aarch64 cross-builds. In addition, Makefile doesn't create arch sub-directories in the case of relocatable builds and test programs under s390x and x86_64 directories fail to build. This is a problem for native and cross-builds. Fix it to create all necessary directories keying off of TEST_GEN_PROGS. The following use-cases work with this change: Native x86_64: make O=/tmp/kselftest -C tools/testing/selftests TARGETS=kvm install \ INSTALL_PATH=$HOME/x86_64 arm64 cross-build: make O=$HOME/arm64_build/ ARCH=arm64 HOSTCC=gcc \ CROSS_COMPILE=aarch64-linux-gnu- defconfig make O=$HOME/arm64_build/ ARCH=arm64 HOSTCC=gcc \ CROSS_COMPILE=aarch64-linux-gnu- all make kselftest-install TARGETS=kvm O=$HOME/arm64_build ARCH=arm64 \ HOSTCC=gcc CROSS_COMPILE=aarch64-linux-gnu- s390x cross-build: make O=$HOME/s390x_build/ ARCH=s390 HOSTCC=gcc \ CROSS_COMPILE=s390x-linux-gnu- defconfig make O=$HOME/s390x_build/ ARCH=s390 HOSTCC=gcc \ CROSS_COMPILE=s390x-linux-gnu- all make kselftest-install TARGETS=kvm O=$HOME/s390x_build/ ARCH=s390 \ HOSTCC=gcc CROSS_COMPILE=s390x-linux-gnu- all No regressions in the following use-cases: make -C tools/testing/selftests TARGETS=kvm make kselftest-all TARGETS=kvm Signed-off-by: Shuah Khan Signed-off-by: Sasha Levin

selftests, kvm: Replace manual MSR defs with common msr-index.h

2020-01-13T16:30:04Z

The kernel's version of msr-index.h was pulled wholesale into tools by commit 444e2ff34df8 ("tools arch x86: Grab a copy of the file containing the MSR numbers"), Use the common msr-index.h instead of manually redefining everything in a KVM-only header. Note, a few MSR-related definitions remain in processor.h because they are not covered by msr-index.h, including the awesomely named APIC_BASE_MSR, which refers to starting index of the x2APIC MSRs, not the actual MSR_IA32_APICBASE, which *is* defined by msr-index.h.

selftests: kvm: Fix libkvm build error

2019-10-03T10:07:58Z

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.
