2025-03-06KVM: riscv: selftests: Allow number of interrupts to be configurableAtish Patra
It is helpful to vary the number of the LCOFI interrupts generated by the overflow test. Allow additional argument for overflow test to accommodate that. It can be easily cross-validated with /proc/interrupts output in the host.

2025-03-06KVM: riscv: selftests: Change command line optionAtish Patra
The PMU test commandline option takes an argument to disable a certain test. The initial assumption behind this was a common use case is just to run all the test most of the time. However, running a single test seems more useful instead. Especially, the overflow test has been helpful to validate PMU virtualizaiton interrupt changes. Switching the command line option to run a single test instead of disabling a single test also allows to provide additional test specific arguments to the test. The default without any options remains unchanged which continues to run all the tests.

2025-03-06KVM: riscv: selftests: Do not start the counter in the overflow handlerAtish Patra
There is no need to start the counter in the overflow handler as we intend to trigger precise number of LCOFI interrupts through these tests. The overflow irq handler has already stopped the counter. As a result, the stop call from the test function may return already stopped error which is fine as well.

Add extra parameters for rcutorture module. One is the "nfakewriters" which is set -1. There will be created number of test-kthreads which correspond to number of CPUs in a test system. Those threads randomly invoke synchronize_rcu() call. Apart of that "rcu_normal" is set to 1, because it is specifically for a normal synchronize_rcu() testing, also a newly added parameter which is "rcu_normal_wake_from_gp" is set to 1 also. That prevents interaction with other callbacks in a system. Reviewed-by: Paul E.

2025-03-04selftests/vDSO: Fix GNU hash table entry size for s390xThomas Weißschuh
Commit 14be4e6f3522 ("selftests: vDSO: fix ELF hash table entry size for s390x") changed the type of the ELF hash table entries to 64bit on s390x. However the *GNU* hash tables entries are always 32bit. The "bucket" pointer is shared between both hash algorithms. On s390, this caused the GNU hash algorithm to access its 32-bit entries as if they were 64-bit, triggering compiler warnings (assignment between "Elf64_Xword *" and "Elf64_Word *") and runtime crashes. Introduce a new dedicated "gnu_bucket" pointer which is used by the GNU hash.

2025-03-04x86/smp: Fix mwait_play_dead() and acpi_processor_ffh_play_dead() noreturn ↵Josh Poimboeuf
behavior Fix some related issues (done in a single patch to avoid introducing intermediate bisect warnings): 1) The SMP version of mwait_play_dead() doesn't return, but its !SMP counterpart does. Make its calling behavior consistent by resolving the !SMP version to a BUG(). It should never be called anyway, this just enforces that at runtime and enables its callers to be marked as __noreturn. 2) While the SMP definition of mwait_play_dead() is annotated as __noreturn, the declaration isn't. Nor is it listed in tools/objtool/noreturns.h. Fix that. 3) Similar to #1, the SMP version of acpi_processor_ffh_play_dead() doesn't return but its !SMP counterpart does. Make the !SMP version a BUG(). It should never be called. 4) acpi_processor_ffh_play_dead() doesn't return, but is lacking any __noreturn annotations. Fix that. This fixes the following objtool warnings: vmlinux.o: warning: objtool: acpi_processor_ffh_play_dead+0x67: mwait_play_dead() is missing a __noreturn annotation vmlinux.o: warning: objtool: acpi_idle_play_dead+0x3c: acpi_processor_ffh_play_dead() is missing a __noreturn annotation Fixes: a7dd183f0b38 ("x86/smp: Allow calling mwait_play_dead with an arbitrary hint") Fixes: 541ddf31e300 ("ACPI/processor_idle: Add FFH state handling") Reported-by: Paul E.
