2022-11-24perf/x86/intel/uncore: Fix reference count leak in __uncore_imc_init_box()Xiongfeng Wang
pci_get_device() will increase the reference count for the returned pci_dev, so tgl_uncore_get_mc_dev() will return a pci_dev with its reference count increased. We need to call pci_dev_put() to decrease the reference count before exiting from __uncore_imc_init_box(). Add pci_dev_put() for both normal and error path.

If we break the loop in sad_cfg_iio_topology() with 'dev' not NULL. We need to call pci_dev_put() to decrease the reference count.

2022-10-27perf: Rewrite core context handlingPeter Zijlstra
There have been various issues and limitations with the way perf uses (task) contexts to track events. Most notable is the single hardware PMU task context, which has resulted in a number of yucky things (both proposed and merged). Notably: - HW breakpoint PMU - ARM big.little PMU / Intel ADL PMU - Intel Branch Monitoring PMU - AMD IBS PMU - S390 cpum_cf PMU - PowerPC trace_imc PMU *Current design:* Currently we have a per task and per cpu perf_event_contexts: task_struct::perf_events_ctxp[] <-> perf_event_context <-> perf_cpu_context ^ | ^ | ^ `---------------------------------' | `--> pmu ---' v ^ perf_event ------' Each task has an array of pointers to a perf_event_context. Each perf_event_context has a direct relation to a PMU and a group of events for that PMU. The task related perf_event_context's have a pointer back to that task. Each PMU has a per-cpu pointer to a per-cpu perf_cpu_context, which includes a perf_event_context, which again has a direct relation to that PMU, and a group of events for that PMU. The perf_cpu_context also tracks which task context is currently associated with that CPU and includes a few other things like the hrtimer for rotation etc. Each perf_event is then associated with its PMU and one perf_event_context. *Proposed design:* New design proposed by this patch reduce to a single task context and a single CPU context but adds some intermediate data-structures: task_struct::perf_event_ctxp -> perf_event_context <- perf_cpu_context ^ | ^ ^ `---------------------------' | | | | perf_cpu_pmu_context <--. | `----. ^ | | | | | | v v | | ,--> perf_event_pmu_context | | | | | | | v v | perf_event ---> pmu ----------------' With the new design, perf_event_context will hold all events for all pmus in the (respective pinned/flexible) rbtrees. This can be achieved by adding pmu to rbtree key: {cpu, pmu, cgroup, group_index} Each perf_event_context carries a list of perf_event_pmu_context which is used to hold per-pmu-per-context state. For example, it keeps track of currently active events for that pmu, a pmu specific task_ctx_data, a flag to tell whether rotation is required or not etc. Additionally, perf_cpu_pmu_context is used to hold per-pmu-per-cpu state like hrtimer details to drive the event rotation, a pointer to perf_event_pmu_context of currently running task and some other ancillary information. Each perf_event is associated to it's pmu, perf_event_context and perf_event_pmu_context. Further optimizations to current implementation are possible. For example, ctx_resched() can be optimized to reschedule only single pmu events. Much thanks to Ravi for picking this up and pushing it towards completion.

2022-10-22io_uring/net: fail zc send when unsupported by socketPavel Begunkov
If a protocol doesn't support zerocopy it will silently fall back to copying. This type of behaviour has always been a source of troubles so it's better to fail such requests instead.

2022-10-22KVM: x86: Add compat handler for KVM_X86_SET_MSR_FILTERAlexander Graf
The KVM_X86_SET_MSR_FILTER ioctls contains a pointer in the passed in struct which means it has a different struct size depending on whether it gets called from 32bit or 64bit code. This patch introduces compat code that converts from the 32bit struct to its 64bit counterpart which then gets used going forward internally. With this applied, 32bit QEMU can successfully set MSR bitmaps when running on 64bit kernels.

In the next patch we want to introduce a second caller to set_msr_filter() which constructs its own filter list on the stack.
