3dbb5b5040 Merge branch 'bpf_enable_stats'
Song Liu says:

====================
run_time_ns is a useful stats for BPF programs. However, it is gated by
sysctl kernel.bpf_stats_enabled. When multiple user space tools are
toggling kernl.bpf_stats_enabled at the same time, they may confuse each
other.

Solve this problem with a new BPF command BPF_ENABLE_STATS.

Changes v8 => v9:
  1. Clean up in selftest (Andrii).
  2. Not using static variable in test program (Andrii).

Changes v7 => v8:
  1. Change name BPF_STATS_RUNTIME_CNT => BPF_STATS_RUN_TIME (Alexei).
  2. Add CHECK_ATTR to bpf_enable_stats() (Alexei).
  3. Rebase (Andrii).
  4. Simplfy the selftest (Alexei).

Changes v6 => v7:
  1. Add test to verify run_cnt matches count measured by the program.

Changes v5 => v6:
  1. Simplify test program (Yonghong).
  2. Rebase (with some conflicts).

Changes v4 => v5:
  1. Use memset to zero bpf_attr in bpf_enable_stats() (Andrii).

Changes v3 => v4:
  1. Add libbpf support and selftest;
  2. Avoid cleaning trailing space.

Changes v2 => v3:
  1. Rename the command to BPF_ENABLE_STATS, and make it extendible.
  2. fix commit log;
  3. remove unnecessary headers.

d46edd671a bpf: Sharing bpf runtime stats with BPF_ENABLE_STATS
Currently, sysctl kernel.bpf_stats_enabled controls BPF runtime stats.
Typical userspace tools use kernel.bpf_stats_enabled as follows:

  1. Enable kernel.bpf_stats_enabled;
  2. Check program run_time_ns;
  3. Sleep for the monitoring period;
  4. Check program run_time_ns again, calculate the difference;
  5. Disable kernel.bpf_stats_enabled.

The problem with this approach is that only one userspace tool can toggle
this sysctl. If multiple tools toggle the sysctl at the same time, the
measurement may be inaccurate.

To fix this problem while keep backward compatibility, introduce a new
bpf command BPF_ENABLE_STATS. On success, this command enables stats and
returns a valid fd. BPF_ENABLE_STATS takes argument "type". Currently,
only one type, BPF_STATS_RUN_TIME, is supported. We can extend the
command to support other types of stats in the future.

With BPF_ENABLE_STATS, user space tool would have the following flow:

  1. Get a fd with BPF_ENABLE_STATS, and make sure it is valid;
  2. Check program run_time_ns;
  3. Sleep for the monitoring period;
  4. Check program run_time_ns again, calculate the difference;
  5. Close the fd.

d09ddd8190 PCI: Allow pci_resize_resource() for devices on root bus
When resizing a BAR, pci_reassign_bridge_resources() is invoked to bring
the bridge windows of parent bridges in line with the new BAR assignment.

This assumes the device whose BAR is being resized lives on a subordinate
bus, but this is not necessarily the case. A device may live on the root
bus, in which case dev->bus->self is NULL, and passing a NULL pci_dev
pointer to pci_reassign_bridge_resources() will cause it to crash.

So let's make the call to pci_reassign_bridge_resources() conditional on
whether dev->bus->self is non-NULL in the first place.

Fixes: 8bb705e3e7 ("PCI: Add pci_resize_resource() for resizing BARs")

c84cb3735f x86/apic: Move TSC deadline timer debug printk
Leon reported that the printk_once() in __setup_APIC_LVTT() triggers a
lockdep splat due to a lock order violation between hrtimer_base::lock and
console_sem, when the 'once' condition is reset via
/sys/kernel/debug/clear_warn_once after boot.

The initial printk cannot trigger this because that happens during boot
when the local APIC timer is set up on the boot CPU.

Prevent it by moving the printk to a place which is guaranteed to be only
called once during boot.

Mark the deadline timer check related functions and data __init while at
it.

fdc63ff0e4 ftrace/x86: Fix trace event registration for syscalls without arguments
The refactoring of SYSCALL_DEFINE0() macros removed the ABI stubs and
simply defines __abi_sys_$NAME as alias of __do_sys_$NAME.

As a result kallsyms_lookup() returns "__do_sys_$NAME" which does not match
with the declared trace event name.

See also commit 1c758a2202 ("tracing/x86: Update syscall trace events to
handle new prefixed syscall func names").

Add __do_sys_ to the valid prefixes which are checked in
arch_syscall_match_sym_name().

ASoC: Intel: boards: sof-wm8804: support for Hifiberry Digiplus boards
Add a new machine driver to interface with WM8804. The code is based
on settings found in sound/soc/bcm/hifiberry-digi.c in the Raspberry
PI tree.

Tested on Up2 with Digi+ IO (capture+playback) and Digi+ PRO (playback
with two local oscillators supported). The codec is clock master in
both cases.

Capture support has known clocking restrictions: the transmitter needs
to be active for the clock recovery, the "Tx Source" mixer set to
"S/PDIF RX". Playback will only work while capture is active.

When Capture is not desired, or when there is no RX connector, the "Tx
Source" mixer should be set to "AIF"

gdb uses ptrace() to peek and poke bytes of the target's address space.
The driver must implement an vm_ops->access() handler or else gdb will
be unable to inspect the pointer and report it as out-of-bounds.
Worse than useless as it causes immediate suspicion of the valid GTT
pointer, distracting the poor programmer trying to find his bug.

66d69e081b selftests: fix kvm relocatable native/cross builds and installs
kvm test Makefile doesn't fully support cross-builds and installs.
UNAME_M = $(shell uname -m) variable is used to define the target
programs and libraries to be built from arch specific sources in
sub-directories.

For cross-builds to work, UNAME_M has to map to ARCH and arch specific
directories and targets in this Makefile.

UNAME_M variable to used to run the compiles pointing to the right arch
directories and build the right targets for these supported architectures.

TEST_GEN_PROGS and LIBKVM are set using UNAME_M variable.
LINUX_TOOL_ARCH_INCLUDE is set using ARCH variable.

x86_64 targets are named to include x86_64 as a suffix and directories
for includes are in x86_64 sub-directory. s390x and aarch64 follow the
same convention. "uname -m" doesn't result in the correct mapping for
s390x and aarch64. Fix it to set UNAME_M correctly for s390x and aarch64
cross-builds.

In addition, Makefile doesn't create arch sub-directories in the case of
relocatable builds and test programs under s390x and x86_64 directories
fail to build. This is a problem for native and cross-builds. Fix it to
create all necessary directories keying off of TEST_GEN_PROGS.

The following use-cases work with this change:

Native x86_64:
make O=/tmp/kselftest -C tools/testing/selftests TARGETS=kvm install \
 INSTALL_PATH=$HOME/x86_64

arm64 cross-build:
make O=$HOME/arm64_build/ ARCH=arm64 HOSTCC=gcc \
	CROSS_COMPILE=aarch64-linux-gnu- defconfig

make O=$HOME/arm64_build/ ARCH=arm64 HOSTCC=gcc \
	CROSS_COMPILE=aarch64-linux-gnu- all

make kselftest-install TARGETS=kvm O=$HOME/arm64_build ARCH=arm64 \
	HOSTCC=gcc CROSS_COMPILE=aarch64-linux-gnu-

s390x cross-build:
make O=$HOME/s390x_build/ ARCH=s390 HOSTCC=gcc \
	CROSS_COMPILE=s390x-linux-gnu- defconfig

make O=$HOME/s390x_build/ ARCH=s390 HOSTCC=gcc \
	CROSS_COMPILE=s390x-linux-gnu- all

make kselftest-install TARGETS=kvm O=$HOME/s390x_build/ ARCH=s390 \
	HOSTCC=gcc CROSS_COMPILE=s390x-linux-gnu- all

No regressions in the following use-cases:
make -C tools/testing/selftests TARGETS=kvm
make kselftest-all TARGETS=kvm

we'd make struct pci_ops const as well, but that becomes pretty

b730d66813 ftrace/selftest: make unresolved cases cause failure if --fail-unresolved set
Currently, ftracetest will return 1 (failure) if any unresolved cases
are encountered.  The unresolved status results from modules and
programs not being available, and as such does not indicate any
issues with ftrace itself.  As such, change the behaviour of
ftracetest in line with unsupported cases; if unsupported cases
happen, ftracetest still returns 0 unless --fail-unsupported.  Here
--fail-unresolved is added and the default is to return 0 if
unresolved results occur.

b74aa02d7a iommu/amd: Fix legacy interrupt remapping for x2APIC-enabled system
Currently, system fails to boot because the legacy interrupt remapping
mode does not enable 128-bit IRTE (GA), which is required for x2APIC
support.

Fix by using AMD_IOMMU_GUEST_IR_LEGACY_GA mode when booting with
kernel option amd_iommu_intr=legacy instead. The initialization
logic will check GASup and automatically fallback to using
AMD_IOMMU_GUEST_IR_LEGACY if GA mode is not supported.
