Add pci_vpd_find_ro_info_keyword() that combines these functionalities. pci_vpd_find_info_keyword() can be phased out once all users are converted.

2021-08-20PCI/VPD: Add pci_vpd_alloc()Heiner Kallweit
Several users of the VPD API use a fixed-size buffer and read the VPD into it for further usage. This requires special handling for the case that the buffer isn't big enough to hold the full VPD data. Also the buffer is often allocated on the stack, which isn't too nice. Add pci_vpd_alloc() to dynamically allocate buffer of the correct size and read VPD into it.

2021-08-12PCI/VPD: Treat invalid VPD like missing VPD capabilityHeiner Kallweit
Exporting sysfs files that can't be accessed doesn't make much sense. Therefore, if either a quirk or the dynamic size calculation result in VPD being marked as invalid, treat this as though the device has no VPD capability. One consequence is that the "vpd" sysfs file is not visible.

Determine VPD size in pci_vpd_init(). Quirks set dev->vpd.len to a non-zero value, so they cause us to skip the dynamic size calculation. Prerequisite is that we move the quirks from FINAL to HEADER so they are run before pci_vpd_init().

2021-08-12PCI/VPD: Remove struct pci_vpd_opsHeiner Kallweit
Some multi-function devices share VPD hardware across functions and don't work correctly for concurrent VPD accesses to different functions. Struct pci_vpd_ops was added by 932c435caba8 ("PCI: Add dev_flags bit to access VPD through function 0") so that on these devices, VPD accesses to any function would always go to function 0. It's easier to just check for the PCI_DEV_FLAGS_VPD_REF_F0 quirk bit in the two places we need it than to deal with the struct pci_vpd_ops. Simplify the code by removing struct pci_vpd_ops and removing the indirect calls.

Reading/writing 4 bytes should be fast enough even on a slow bus, therefore pci_vpd_wait() doesn't have to be interruptible. Making it uninterruptible allows to simplify the code. In addition make VPD writes uninterruptible in general. It's about vital data, and allowing writes to be interruptible may leave the VPD in an inconsistent state.

2021-08-09PCI/VPD: Remove pci_vpd_size() old_size argumentHeiner Kallweit
vpd->len is initialized to PCI_VPD_MAX_SIZE, and if a quirk is used to set a specific VPD size, then pci_vpd_set_size() sets vpd->valid, resulting in pci_vpd_size() not being called. Therefore we can remove the old_size argument. Note that we don't have to check off < PCI_VPD_MAX_SIZE because that's implicitly done by pci_read_vpd().

2021-08-09PCI/VPD: Allow access to valid parts of VPD if some is invalidBjorn Helgaas
Previously, if we found any error in the VPD, we returned size 0, which prevents access to all of VPD. But there may be valid resources in VPD before the error, and there's no reason to prevent access to those. "off" covers only VPD resources known to have valid header tags.

2021-08-09PCI/VPD: Don't check Large Resource Item Names for validityBjorn Helgaas
VPD consists of a series of Small and Large Resources. Computing the size of VPD requires only the length of each, which is specified in the generic tag of each resource. We only expect to see ID_STRING, RO_DATA, and RW_DATA in VPD, but it's not a problem if it contains other resource types because all we care about is the size.

2021-07-11mm/rmap: fix old bug: munlocking THP missed other mlocksHugh Dickins
The kernel recovers in due course from missing Mlocked pages: but there was no point in calling page_mlock() (formerly known as try_to_munlock()) on a THP, because nothing got done even when it was found to be mapped in another VM_LOCKED vma. It's true that we need to be careful: Mlocked accounting of pte-mapped THPs is too difficult (so consistently avoided); but Mlocked accounting of only-pmd-mapped THPs is supposed to work, even when multiple mappings are mlocked and munlocked or munmapped. Refine the tests. There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so page_mlock_one() does not even have to worry about that complication. (I said the kernel recovers: but would page reclaim be likely to split THP before rediscovering that it's VM_LOCKED?

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux Pull more perf tool updates from Arnaldo Carvalho de Melo: "New features: - Enable use of BPF counters with 'perf stat --for-each-cgroup', using per-CPU 'cgroup-switch' events with an attached BPF program that does aggregation per-cgroup in the kernel instead of using per-cgroup perf events. - Add Topdown metrics L2 events as default events in 'perf stat' for systems having those events. Hardware tracing: - Add a config for max loops without consuming a packet in the Intel PT packet decoder, set via 'perf config intel-pt.max-loops=N' Hardware enablement: - Disable misleading NMI watchdog message in 'perf stat' on hybrid systems such as Intel Alder Lake. - Add a dummy event on hybrid systems to collect metadata records. - Add 24x7 nest metric events for the Power10 platform. Fixes: - Fix event parsing for PMUs starting with the same prefix. - Fix the 'perf trace' 'trace' alias installation dir. - Fix buffer size to report iregs in perf script python scripts, supporting the extended registers in PowerPC. - Fix overflow in elf_sec__is_text(). - Fix 's' on source line when disasm is empty in the annotation TUI, accessible via 'perf annotate', 'perf report' and 'perf top'. - Plug leaks in scandir() returned dirent entries in 'perf test' when sorting the shell tests. - Fix --task and --stat with pipe input in 'perf report'. - Fix 'perf probe' use of debuginfo files by build id. - If a DSO has both dynsym and symtab ELF sections, read from both when loading the symbol table, fixing a problem processing Fedora 32 glibc DSOs. Libraries: - Add grouping of events to libperf, from code in tools/perf, allowing libperf users to use that mode. Misc: - Filter plt stubs from the 'perf probe --functions' output. - Update UAPI header copies for asound, DRM, mman-common.h and the ones affected by the quotactl_fd syscall" * tag 'perf-tools-for-v5.14-2021-07-10' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: (29 commits) perf test: Add free() calls for scandir() returned dirent entries libperf: Add tests for perf_evlist__set_leader() libperf: Remove BUG_ON() from library code in get_group_fd() libperf: Add group support to perf_evsel__open() perf tools: Fix pattern matching for same substring in different PMU type perf record: Add a dummy event on hybrid systems to collect metadata records perf stat: Add Topdown metrics L2 events as default events libperf: Adopt evlist__set_leader() from tools/perf as perf_evlist__set_leader() libperf: Move 'nr_groups' from tools/perf to evlist::nr_groups libperf: Move 'leader' from tools/perf to perf_evsel::leader libperf: Move 'idx' from tools/perf to perf_evsel::idx libperf: Change tests to single static and shared binaries perf intel-pt: Add a config for max loops without consuming a packet perf stat: Disable the NMI watchdog message on hybrid perf vendor events power10: Adds 24x7 nest metric events for power10 platform perf script python: Fix buffer size to report iregs in perf script perf trace: Fix the perf trace link location perf top: Fix overflow in elf_sec__is_text() perf annotate: Fix 's' on source line when disasm is empty perf probe: Do not show @plt function by default ...

2021-07-10mm/page_alloc: Revert pahole zero-sized workaroundMel Gorman
Commit dbbee9d5cd83 ("mm/page_alloc: convert per-cpu list protection to local_lock") folded in a workaround patch for pahole that was unable to deal with zero-sized percpu structures. A superior workaround is achieved with commit a0b8200d06ad ("kbuild: skip per-CPU BTF generation for pahole v1.18-v1.21"). This patch reverts the dummy field and the pahole version check.
