Kernel crashes if power pmu is not registered and user tries to dump regs with 'echo p > /proc/sysrq-trigger'. Sample log: Unable to handle kernel paging request for data at address 0x0008 Faulting instruction address: 0xc00d52f0 NIP [c00d52f0]

[RESEND PATCH v4 1/6] libsas: Use dynamic alloced work to avoid sas event lost

Now libsas hotplug work is static, every sas event type has its own static work, LLDD driver queues the hotplug work into shost->work_q. If LLDD driver burst posts lots hotplug events to libsas, the hotplug events may pending in the workqueue like shost->work_q new work[PORTE_BYTES_DMAED] -->

In commit 87c8331f ([SCSI] libsas: prevent domain rediscovery competing with ata error handling) introduced disco mutex to prevent rediscovery competing with ata error handling and put the whole revalidation in the mutex. But the rphy add/remove needs to wait for the error handling which also

[RESEND PATCH v4 3/6] libsas: make the event threshold configurable

[RESEND PATCH v4 4/6] libsas: Use new workqueue to run sas event and disco event

Now all libsas works are queued to scsi host workqueue, include sas event work post by LLDD and sas discovery work, and a sas hotplug flow may be divided into several works, e.g libsas receive a PORTE_BYTES_DMAED event, currently we process it as following steps: sas_form_port --- run in work in

[RESEND PATCH v4 0/6] Enhance libsas hotplug feature

Thanks Martin K. Petersen for applied some of the tidy-up patches. So I do not have to maintain these patches out of the tree. I will only send the reset of them in the next days if needed. Now the libsas hotplug has some issues, Dan Williams report a similar bug here before

[RESEND PATCH v4 2/6] libsas: shut down the PHY if events reached the threshold

If the PHY burst too many events, we will alloc a lot of events for the worker. This may leads to memory exhaustion. Dan Williams suggested to shut down the PHY if the events reached the threshold, because in this case the PHY may have gone into some erroneous state. Users can re-enable the PHY
