KVM: PPC: Book3S HV: Mask off LPCR_MER for a vCPU before running it to avoid spurious interrupts 2024-11-06T06:06:09+00:00 Gautam Menghani gautam@linux.ibm.com 2024-10-28T09:04:09+00:00 a373830f96db288a3eb43a8692b6bcd0bd88dfe1 Running a L2 vCPU (see [1] for terminology) with LPCR_MER bit set and no pending interrupts results in that L2 vCPU getting an infinite flood of spurious interrupts. The 'if check' in kvmhv_run_single_vcpu() sets the LPCR_MER bit if there are pending interrupts. The spurious flood problem can be observed in 2 cases: 1. Crashing the guest while interrupt heavy workload is running a. Start a L2 guest and run an interrupt heavy workload (eg: ipistorm) b. While the workload is running, crash the guest (make sure kdump is configured) c. Any one of the vCPUs of the guest will start getting an infinite flood of spurious interrupts. 2. Running LTP stress tests in multiple guests at the same time a. Start 4 L2 guests. b. Start running LTP stress tests on all 4 guests at same time. c. In some time, any one/more of the vCPUs of any of the guests will start getting an infinite flood of spurious interrupts. The root cause of both the above issues is the same: 1. A NMI is sent to a running vCPU that has LPCR_MER bit set. 2. In the NMI path, all registers are refreshed, i.e, H_GUEST_GET_STATE is called for all the registers. 3. When H_GUEST_GET_STATE is called for LPCR, the vcpu->arch.vcore->lpcr of that vCPU at L1 level gets updated with LPCR_MER set to 1, and this new value is always used whenever that vCPU runs, regardless of whether there was a pending interrupt. 4. Since LPCR_MER is set, the vCPU in L2 always jumps to the external interrupt handler, and this cycle never ends. Fix the spurious flood by masking off the LPCR_MER bit before running a L2 vCPU to ensure that it is not set if there are no pending interrupts. [1] Terminology: 1.

Commit ac9f97ff8b32 ("powerpc/8xx: Inconditionally use task PGDIR in
DTLB misses") relies on re-reading DAR register to know if an error is
due to a missing copy of a PMD entry in task's PGDIR, allthough DAR
was already read in the exception prolog and copied into thread
struct. This is because is it done very early in the exception and
there are not enough registers available to keep a pointer to thread
struct.

However, dcbz instruction is buggy and doesn't update DAR register on
fault. That is detected and generates a call to FixupDAR workaround
which updates DAR copy in thread struct but doesn't fix DAR register.

Let's fix DAR in addition to the update of DAR copy in thread struct.

But Go requires a different trampoline for every call, and there's no reason that new Go code needs to be broken and add more bugs. So remove -ffixed-r30 for getrandom.
