====================
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.
====================

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.

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.

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.

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"

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:

The dcn20_validate_bandwidth function would have code touching the

CG/PG ungate is already performed in ip_suspend_phase1. Otherwise,
the CG/PG ungate will be performed twice. That will cause gfxoff
disablement is performed twice also on runpm enter while gfxoff
enablemnt once on rump exit. That will put gfxoff into disabled
state.

This sequence change should be safe as what did in ip_suspend_phase1
is to suspend DCE only. And this is a prerequisite for coming

At the first time update_mute_led() gets called, if channels are already

So set led_value to -1 as an uninitialized state, to update the correct

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.
