ALSA: Drop hackish GFP giveaway for CONTINUOUS pages
This is a series of cleanup patches for dropping the current hackish way of passing the GFP_* flags for CONTINOUS and VMALLOC memory allocations. There are only three users for this legacy feature, and all of them seem superfluous. And, if any driver requires the memory restriction in future, it can now pass the proper device pointer for specifying the DMA mask.

perf tools: Support reading PERF_FORMAT_LOST
The recent kernel added lost count can be read from either read(2) or ring buffer data with PERF_SAMPLE_READ. As it's a variable length data we need to access it according to the format info.
But for perf tools use cases, PERF_FORMAT_ID is always set. So we can only check PERF_FORMAT_LOST bit to determine the data format.
Add sample_read_value_size() and next_sample_read_value() helpers to make it a bit easier to access. Use them in all places where it reads the struct sample_read_value.

Merge tag 'perf-tools-for-v6.0-2022-08-04' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
Pull perf tools updates from Arnaldo Carvalho de Melo:
- Introduce 'perf lock contention' subtool, using new lock contention tracepoints and using BPF for in kernel aggregation and then userspace processing using the perf tooling infrastructure for resolving symbols, target specification, etc.
Since the new lock contention tracepoints don't provide lock names, get up to 8 stack traces and display the first non-lock function symbol name as a caller:
$ perf lock report -F acquired,contended,avg_wait,wait_total
Name acquired contended avg wait total wait
update_blocked_a... 40 40 3.61 us 144.45 us kernfs_fop_open+... 5 5 3.64 us 18.18 us _nohz_idle_balance 3 3 2.65 us 7.95 us tick_do_update_j... 1 1 6.04 us 6.04 us ep_scan_ready_list 1 1 3.93 us 3.93 us
Supports the usual 'perf record' + 'perf report' workflow as well as a BCC/bpftrace like mode where you start the tool and then press control+C to get results:
$ sudo perf lock contention -b ^C contended total wait max wait avg wait type caller

- Add new 'perf kwork' tool to trace time properties of kernel work (such as softirq, and workqueue), uses eBPF skeletons to collect info in kernel space, aggregating data that then gets processed by the userspace tool, e.g.:

- Add support for new AMD IBS (Instruction Based Sampling) features:
With the DataSrc extensions, the source of data can be decoded among: - Local L3 or other L1/L2 in CCX. - A peer cache in a near CCX. - Data returned from DRAM. - A peer cache in a far CCX. - DRAM address map with "long latency" bit set. - Data returned from MMIO/Config/PCI/APIC. - Extension Memory (S-Link, GenZ, etc - identified by the CS target and/or address map at DF's choice). - Peer Agent Memory.
- Support hardware tracing with Intel PT on guest machines, combining the traces with the ones in the host machine.
- Add a "-m" option to 'perf buildid-list' to show kernel and modules build-ids, to display all of the information needed to do external symbolization of kernel stack traces, such as those collected by bpf_get_stackid().
- Add arch TSC frequency information to perf.data file headers.
- Handle changes in the binutils disassembler function signatures in perf, bpftool and bpf_jit_disasm (Acked by the bpftool maintainer).
- Fix building the perf perl binding with the newest gcc in distros such as fedora rawhide, where some new warnings were breaking the build as perf uses -Werror.
- Add 'perf test' entry for branch stack sampling.
- Add ARM SPE system wide 'perf test' entry.
- Add user space counter reading tests to 'perf test'.
- Build with python3 by default, if available.
- Add python converter script for the vendor JSON event files.
- Update vendor JSON files for most Intel cores.
- Add vendor JSON File for Intel meteorlake.
- Add Arm Cortex-A78C and X1C JSON vendor event files.
- Add workaround to symbol address reading from ELF files without phdr, falling back to the previoous equation.
- Convert legacy map definition to BTF-defined in the perf BPF script test.
- Rework prologue generation code to stop using libbpf deprecated APIs.
- Add default hybrid events for 'perf stat' on x86.
- Add topdown metrics in the default 'perf stat' on the hybrid machines (big/little cores).
- Prefer sampled CPU when exporting JSON in 'perf data convert'
- Fix ('perf stat CSV output linter') and ("Check branch stack sampling") 'perf test' entries on s390.

perf evsel: Add arch_evsel__hw_name()
The commit 55bcf6ef314ae8ba ("perf: Extend PERF_TYPE_HARDWARE and PERF_TYPE_HW_CACHE") extends the two types to become PMU aware types for a hybrid system. However, current evsel__hw_name doesn't take the PMU type into account. It mistakenly returns the "unknown-hardware" for the hardware event with a specific PMU type.
Add an arch specific arch_evsel__hw_name() to specially handle the PMU aware hardware event.
Currently, the extend PERF_TYPE_HARDWARE and PERF_TYPE_HW_CACHE is only supported by X86. Only implement the specific arch_evsel__hw_name() for X86 in the patch.
Nothing is changed for the other archs.

perf tools: Add machine_pid and vcpu to perf_sample
When parsing a sample with a sample ID, copy machine_pid and vcpu from perf_sample_id to perf_sample.
Note, machine_pid will be zero when unused, so only a non-zero value represents a guest machine. vcpu should be ignored if machine_pid is zero.
Note also, machine_pid is used with events that have come from injecting a guest perf.data file, however guest events recorded on the host (i.e. using perf kvm) have the (QEMU) hypervisor process pid to identify them - refer machines__find_for_cpumode().

Factor out evsel__id_hdr_size() so it can be reused.
This is needed by perf inject. When injecting events from a guest perf.data file, there is a possibility that the sample ID numbers conflict. To re-write an ID sample, the old one needs to be removed first, which means determining how big it is with evsel__id_hdr_size() and then subtracting that from the event size.
