From 3047766bc6ec9c6bc9ece85b45a41ff401e8d988 Mon Sep 17 00:00:00 2001 From: Niklas Schnelle Date: Thu, 18 Jun 2020 17:16:27 +0200 Subject: [PATCH 1/6] s390/pci: fix enabling a reserved PCI function In usual IPL or hot plug scenarios a zPCI function transitions directly from reserved (invisible to Linux) to configured state or is configured by Linux itself using an SCLP, however it can also first go from reserved to standby and then from standby to configured without Linux initiative. In this scenario we first get a PEC event 0x302 and then 0x301. This may happen for example when the device is deconfigured at another LPAR and made available for this LPAR. It may also happen under z/VM when a device is attached while in some inconsistent state. However when we get the 0x301 the device is already known to zPCI so calling zpci_create() will add it twice resulting in the below BUG. Instead we should only enable the existing device and finally scan it through the PCI subsystem. list_add double add: new=00000000ed5a9008, prev=00000000ed5a9008, next=0000000083502300. kernel BUG at lib/list_debug.c:31!

This is true for s390 at least since commit 6471384af2a6 ("mm: security: introduce init_on_alloc=1 and init_on_free=1 boot options"). To avoid the following WARN: static_key_enable_cpuslocked(): static key 'init_on_alloc+0x0/0x40' used before call to jump_label_init() call jump_label_init() just before parse_early_param(). jump_label_init() is safe to call multiple times (x86 does that), doesn't do any memory allocations and hence should be safe to call that early.

The sampling facility collects samples in a ring buffer which includes only the instruction address the samples were taken. When the ring buffer hits a watermark, a measurement alert interrupt is triggered and handled by the performance measurement unit (PMU) device driver. It collects the samples and feeds each sample to the perf ring buffer in the common code via functions perf_prepare_sample()/perf_output_sample(). When function perf_prepare_sample() is called to collect sample data's callchain, user register values or stack area, invalid data is picked, because the context of the collected information does not match the context when the sample was taken. There is currently no way to provide the callchain and other information, because the hardware sampler does not collect this information. Therefore prohibit sampling when the user requests a callchain graph from the hardware sampler. Return -EOPNOTSUPP to the user in this case. If call chains are really wanted, users need to specify software event cpu-clock to get the callchain information from a software event.
