7ab5ff4937 tools/power turbostat: Fix Core C6 residency on Atom CPUs
For Atom CPUs that have core cstate deeper than C6,
MSR_CORE_C6_RESIDENCY actually returns the residency for both CC6 and
deeper Core cstates.
Thus, the real Core C6 residency should be the subtraction of
MSR_CORE_C6_RESIDENCY return value and MSR_CORE_C6_RESIDENCY return value.

aeb01e6d71 tools/power turbostat: Print the C-state Pre-wake settings
C-state pre-wake setting[1] is an optimization for some Intel CPUs to
be woken up from deep C-states in order to reduce latency. According to
the spec, the BIT30 is the C-state Pre-wake Disable. Expose this setting
accordingly.
Sample output from turbostat:
...
cpu51: MSR_IA32_POWER_CTL: 0x1a00a40059 (C1E auto-promotion: DISabled)
C-state Pre-wake: ENabled
cpu51: MSR_TURBO_RATIO_LIMIT: 0x2021212121212224

8c69da2930 tools/power turbostat: Enable tsc_tweak for Elkhart Lake and Jasper Lake
It was found that on Elkhart Lake the TSC frequency is driven by
a separate crystal-clock domain, which is different from the
BCLK domain which includes mperf. This has result in small different
speed thus inconsistence between TSC and the mperf, which caused the
Busy% to be higher than 100%. On this platform it seems that the mperf
runs faster than tsc when the CPU is 100% utilized:
delta tsc(18815473183) < delta mperf(18958403680) for 10 seconds.

To align TSC with mperf, leverage the tsc_tweak mechanism introduced for
cores newer than Skylake, so that TSC and mperf would be calculated in
the same domain.

25368d7cef tools/power/turbostat: Remove Package C6 Retention on Ice Lake Server
Currently the turbostat treats ICX the same way as SKX and shares the
code among them. But one difference is that ICX does not support Package
C6 Retention, unlike SKX and CLX.

So this patch:

1. Splitting SKX and ICX in turbostat.
2. Removing Package C6 Rentention for ICX.

And after this split, it would be easier to cutomize Ice Lake Server
in turbostat in the future.

13a779de41 tools/power turbostat: Fix offset overflow issue in index converting
The idx_to_offset() function returns type int (32-bit signed), but
MSR_PKG_ENERGY_STAT is u32 and would be interpreted as a negative number.
The end result is that it hits the if (offset < 0) check in update_msr_sum()
which prevents the timer callback from updating the stat in the background when
long durations are used. The similar issue exists in offset_to_idx() and
update_msr_sum(). Fix this issue by converting the 'int' to 'off_t' accordingly.

301b1d3a91 tools/power/turbostat: Fix turbostat for AMD Zen CPUs
It was reported that on Zen+ system turbostat started exiting,
which was tracked down to the MSR_PKG_ENERGY_STAT read failing because
offset_to_idx wasn't returning a non-negative index.

This patch combined the modification from Bingsong Si and
Bas Nieuwenhuizen and addd the MSR to the index system as alternative for
MSR_PKG_ENERGY_STATUS.

Apparently the TCC offset should not be used to adjust what temperature

(on most systems, TCC offset is 0, FWIW)

2af4f9b859 tools/power turbostat: add built-in-counter for IPC -- Instructions per Cycle
Use linux-perf to access the hardware instructions-retired counter.
This is necessary because the counter is not enabled by default,
and also the counter is prone to roll-over -- both of which
perf manages.

It is not necessary to use perf for the cycle counter,
because turbostat already needs to collect delta-aperf
to calcuate frequency.

7f1b11ba35 tools/power/turbostat: Fallback to an MSR read for EPB
Commit

  6d6501d912 ("tools/power/turbostat: Read energy_perf_bias from sysfs")

converted turbostat to read the energy_perf_bias value from sysfs.
However, older kernels which do not have that file yet, would fail. For
those, fall back to the MSR reading.

Remove the family check for accessing the MSR_AMD_HWCR MSR and replace
it with a cpupower cap flag.

This update also allows for the removal of the local cpupower_cpu_info
variable in cpufreq_has_boost_support() since we no longer need it to

The pscur variable is set but not uused, just remove it.

This may have previsously been set to validate the MSR_AMD_PSTATE_STATUS
MSR. With the addition of the CPUPOWER_CAP_AMD_HW_PSTATE cap flag this
is no longer needed since the cpuid bit to enable this cap flag also
validates that the MSR_AMD_PSTATE_STATUS MSR is present.

Add a check in get_cpu_info() for the ability to read frequencies

The cpuid flag is set when CPUID_80000007_EDX[7] is set,
which is all families >= 10h. The check excludes family 14h
because HW pstate reporting was not implemented on family 14h.

The msr_pstate union struct named fam17h_bits is misleading since
this is the struct to use for all families >= 0x17, not just
for family 0x17. Rename the bits structs to be 'pstate' (for pre
family 17h CPUs) and 'pstatedef' (for CPUs since fam 17h) to align
closer with PPR/BDKG (1) naming.

There are no functional changes as part of this update.

When BIOS disables turbo, The scaling_max_freq in cpufreq sysfs will be
limited to config level 0 base frequency. But when user selects a higher
config levels, this will result in higher base frequency. But since
scaling_max_freq is still old base frequency, the performance will still
be limited. So when the turbo is disabled and cpufreq base_frequency is
higher than scaling_max_freq, update the scaling_max_freq to the

Core:
 
  - support "prefer busy polling" NAPI operation mode, where we defer softirq
    for some time expecting applications to periodically busy poll
 
  - AF_XDP: improve efficiency by more batching and hindering
            the adjacency cache prefetcher
 
  - af_packet: make packet_fanout.arr size configurable up to 64K
 
  - tcp: optimize TCP zero copy receive in presence of partial or unaligned
         reads making zero copy a performance win for much smaller messages
 
  - XDP: add bulk APIs for returning / freeing frames

    enhancements
 
  - BPF implement task local storage for BPF LSM
 
  - allow the FENTRY/FEXIT/RAW_TP tracing programs to use bpf_sk_storage
 
 Protocols:
 
  - mptcp: improve multiple xmit streams support, memory accounting and
           many smaller improvements
 
  - TLS: support CHACHA20-POLY1305 cipher
 
  - seg6: add support for SRv6 End.DT4/DT6 behavior
 
  - sctp: Implement RFC 6951: UDP Encapsulation of SCTP
 
  - ppp_generic: add ability to bridge channels directly
 
  - bridge: Connectivity Fault Management (CFM) support as is defined in
            IEEE 802.1Q section 12.14.

  - phy: add support for shared interrupts; get rid of multiple driver
         APIs and have the drivers write a full IRQ handler, slight growth
 	of driver code should be compensated by the simpler API which
 	also allows shared IRQs
 
  - add common code for handling netdev per-cpu counters
 
  - move TX packet re-allocation from Ethernet switch tag drivers to
    a central place
 
  - improve efficiency and rename nla_strlcpy

an attempt to have userspace tools not poke at naked MSRs. This round
 deals with MSR_IA32_ENERGY_PERF_BIAS and removes direct poking into it
 by our in-tree tools in favor of the proper "energy_perf_bias" sysfs
 interface which we already have.
 
 In addition, the msr.ko write filtering's error message points to a new
 summary page which contains the info we collected from helpful reporters
 about which userspace tools write MSRs:

 along with the current status of their conversion.

6c4832253a tools/power/x86/intel-speed-select: Account for missing sysfs for die_id
Some older kernels will not have support to get CPU die_id from the
sysfs. This requires several back ports. But the tool depends on getting
die_id to match to correct CPU.

Relax this restriction and use die_id as 0 when die_id is missing. This
is not a problem as we don't have any multi-die processors with Intel SST
support.

This helps in running this tool on older kernels with just Intel SST
drivers back ported.

07f262d80d tools/power/x86/intel-speed-select: Read TRL from mailbox
When SST-PP feature is not present, the TRL (Turbo Ratio Limits)
is read from MSRs. This is done as the mailbox command will fail
on Skylake-X based platform. But for IceLake servers, mailbox
commands can still be used. So add a check to allow for non Skylake
based platforms to read from mail box commands.

This cpupower update for Linux 5.11-rc1 consists of a change to provide
 online and offline CPU information. This change makes it easier to keep
 track of offline cpus whose cpuidle or cpufreq property aren't changed
 when updates are made to online cpus.

- if wakeups occur in s2idle: "freeze time: N (-x ms waking y times) ms"

 - change FREEZELOOP and FREEZEWAKE to S2LOOP and S2WAKE for brevity

 - returns all sysfs vals to their initial state after testing

 - use the dmesg log for debugging until the test is completed,
   instrument the executeSuspend process to have a full trace,
   if test completes, formal dmesg log overwrites the debug log

 - fix CPU_ON and CPU_OFF devices in the timeline, should include [n]

====================
pull-request: bpf-next 2020-11-14

1) Add BTF generation for kernel modules and extend BTF infra in kernel
   e.g. support for split BTF loading and validation, from Andrii Nakryiko.

2) Support for pointers beyond pkt_end to recognize LLVM generated patterns
   on inlined branch conditions, from Alexei Starovoitov.

3) Implements bpf_local_storage for task_struct for BPF LSM, from KP Singh.

4) Enable FENTRY/FEXIT/RAW_TP tracing program to use the bpf_sk_storage
   infra, from Martin KaFai Lau.

5) Add XDP bulk APIs that introduce a defer/flush mechanism to optimize the
   XDP_REDIRECT path, from Lorenzo Bianconi.

6) Fix a potential (although rather theoretical) deadlock of hashtab in NMI
   context, from Song Liu.

7) Fixes for cross and out-of-tree build of bpftool and runqslower allowing build
   for different target archs on same source tree, from Jean-Philippe Brucker.

8) Fix error path in htab_map_alloc() triggered from syzbot, from Eric Dumazet.

9) Move functionality from test_tcpbpf_user into the test_progs framework so it
   can run in BPF CI, from Alexander Duyck.

10) Lift hashtab key_size limit to be larger than MAX_BPF_STACK, from Florian Lehner.

Note that for the fix from Song we have seen a sparse report on context
imbalance which requires changes in sparse itself for proper annotation
detection where this is currently being discussed on linux-sparse among
developers [0]. Once we have more clarification/guidance after their fix,
Song will follow-up.
