From 8f5c7579caba587a72ed91c7d76028efb8adb168 Mon Sep 17 00:00:00 2001 From: Nathan Lynch Date: Wed, 14 Nov 2007 03:15:13 +1100 Subject: [POWERPC] Fix multiple bugs in rtas_ibm_suspend_me code There are several issues with the rtas_ibm_suspend_me code, which enables platform-assisted suspension of an LPAR as covered in PAPR 2.2. 1.) rtas_ibm_suspend_me uses on_each_cpu() to invoke rtas_percpu_suspend_me on all cpus via IPI: if (on_each_cpu(rtas_percpu_suspend_me, &data, 1, 0)) ... 'data' is on the calling task's stack, but rtas_ibm_suspend_me takes no measures to ensure that all instances of rtas_percpu_suspend_me are finished accessing 'data' before returning. This can result in the IPI'd cpus accessing random stack data and getting stuck in H_JOIN. This is addressed by using an atomic count of workers and a completion on the stack. 2.) rtas_percpu_suspend_me is needlessly calling H_JOIN in a loop. The only event that can cause a cpu to return from H_JOIN is an H_PROD from another cpu or a NMI/system reset. Each cpu need call H_JOIN only once per suspend operation. Remove the loop and the now unnecessary 'waiting' state variable. 3.) H_JOIN must be called with MSR[EE] off, but lazy interrupt disabling may cause the caller of rtas_ibm_suspend_me to call H_JOIN with it on; the local_irq_disable() in on_each_cpu() is not sufficient. Fix this by explicitly saving the MSR and clearing the EE bit before calling H_JOIN. 4.) H_PROD is being called with the Linux logical cpu number as the parameter, not the platform interrupt server value. (It's also being called for all possible cpus, which is harmless, but unnecessary.) This is fixed by calling H_PROD for each online cpu using get_hard_smp_processor_id(cpu) for the argument.

The actual rtas call "os-term" will not ever return, and so calling it from the panic notifier is too early. Instead, call it from the machine_reset() call. This splits the rtas_os_term() routine into two: one part to capture the kernel panic message, invoked during the panic notifier, and another part that is invoked during machine_reset(). Prior to this patch, the os-term call was never being made, because panic_timeout was always non-zero. Calling os-term helps keep the hypervisor happy! We have to keep the hypervisor happy to avoid service, dump and error reporting problems.
