torture: Prevent jitter from delaying build-only runs

2016-11-14T18:48:59+00:00

Currently, if the --jitter flag specifies jitter for a --build-only run, the system will obediently build a kernel, refuse to launch it, launch the requested number of jitter processes, and wait for the specified kernel run time, which defaults to 30 minutes. This is of course quite pointless. This commit therefore disables jitter on build-only runs. Signed-off-by: Paul E. McKenney Reviewed-by: Josh Triplett

torture: Inflict default jitter

2016-06-14T23:03:32+00:00

This commit enables jitter by default. It may be manually disabled by passing "--jitter 0" to kvm.sh. Signed-off-by: Paul E. McKenney

rcutorture: Drop "-soundhw pcspkr" from x86 boot arguments

2016-06-14T23:03:30+00:00

Because recent testing shows that "-soundhw pcspkr" is no longer required in the kernel boot arguments, this commit drops this qemu argument. Reported-by: Josh Triplett Signed-off-by: Paul E. McKenney

rcutorture: Don't specify the cpu type of QEMU on PPC

2016-06-14T23:03:30+00:00

Do not restrict the cpu type to POWER7 for QEMU as we have POWER8 now. Signed-off-by: Boqun Feng Reviewed-by: Josh Triplett Signed-off-by: Paul E. McKenney

rcutorture: Make -soundhw a x86 specific option

2016-06-14T23:03:29+00:00

The option "-soundhw pcspk" gives me a error on PPC as follow: qemu-system-ppc64: ISA bus not available for pcspk This means this option doesn't work on ppc by default. So simply make this an x86-specific option via identify_qemu_args(). Signed-off-by: Boqun Feng Reviewed-by: Josh Triplett Signed-off-by: Paul E. McKenney

rcutorture: Use vmlinux as the fallback kernel image

2016-06-14T23:03:29+00:00

The vmlinux image is available for all the architectures, and suitable for running a KVM guest by QEMU, besides, we used to copy the vmlinux to $resdir anyway. Therefore it makes sense to use it as the fallback kernel image for rcutorture KVM tests. This patch makes identify_boot_image() return vmlinux if ${TORTURE_BOOT_IMAGE} is not set on non-x86 architectures, also fixes several places that hard-code "bzImage" as $KERNEL. This also fixes a problem that PPC doesn't have a bzImage file as build results. Signed-off-by: Boqun Feng Reviewed-by: Josh Triplett Signed-off-by: Paul E. McKenney

torture: Add starvation events to error summary

2016-06-14T23:02:17+00:00

This commit adds a string of the form "Starves: 10" to the summary line for error conditions found in the console output. Signed-off-by: Paul E. McKenney

torture: Forgive lengthy trace dumps and preemption

2016-06-14T23:02:16+00:00

This commit avoids killing qemu if a trace dump is making progress or if console log output is continuing and the console log timestamp does not exceed the total plus grace period. Signed-off-by: Paul E. McKenney

rcutorture: Don't rebuild identical kernel

2016-04-21T20:47:04+00:00

Currently, if the user specifies multiple runs of a given test configuration, the scripting does multiple kernel builds. This wastes both time and disk space, so this commit makes the scripting use the first build for all runs of a given test configuration. Signed-off-by: Paul E. McKenney

rcutorture: Add OS-jitter capability
