tools/power/x86/intel-speed-select: Set higher of cpuinfo_max_freq or base_frequency
In some case when BIOS disabled turbo, cpufreq cpuinfo_max_freq can be lower than base_frequency at higher config level. So, in that case set scaling_min_freq to base_frequency.

tools/power/x86/intel-speed-select: Set scaling_max_freq to base_frequency
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 base_frequency.

Networking updates for 5.11
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
- sched: support fragmenting IP packets as they come out of conntrack
- net: allow virtual netdevs to forward UDP L4 and fraglist GSO skbs
BPF:
- BPF switch from crude rlimit-based to memcg-based memory accounting
- BPF type format information for kernel modules and related tracing
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.
Drivers:
- mlx5: make use of the new auxiliary bus to organize the driver internals
- mlx5: more accurate port TX timestamping support
- mlxsw:
- improve the efficiency of offloaded next hop updates by using
the new nexthop object API

- iwlwifi: support new 6 GHz frequency band
- ath11k: Fast Initial Link Setup (FILS)
- mt7915: dual band concurrent (DBDC) support
- net: ipa: add basic support for IPA v4.5
Refactor:
- a few pieces of in_interrupt() cleanup work from Sebastian Andrzej Siewior
- 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

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.

cpupower: Provide online and offline CPU information
When a user tries to modify cpuidle or cpufreq properties on offline CPUs, the tool returns success (exit status 0) but also does not provide any warning message regarding offline cpus that may have been specified but left unchanged. In case of all or a few CPUs being offline, it can be difficult to keep track of which CPUs didn't get the new frequency or idle state set. Silent failures are difficult to keep track of when there are a huge number of CPUs on which the action is performed. This patch adds helper functions to find both online and offline CPUs and print them out accordingly. We use these helper functions in cpuidle-set and cpufreq-set to print an additional message if the user attempts to modify offline cpus. Reported-by: Pavithra R.

it from failing to enumerate the Psys RAPL domain (Zhang Rui).
- Allow acpi-cpufreq to use ACPI _PSD information with Family 19 and
later AMD chips (Wei Huang).
- Update the driver assumptions comment in intel_idle and fix a
kerneldoc comment in the runtime PM framework (Alexander Monakov,
Bean Huo).
- Avoid unnecessary resets of the cached frequency in the schedutil
cpufreq governor to reduce overhead (Wei Wang).
- Clean up the cpufreq core a bit (Viresh Kumar).
- Make assorted minor janitorial changes (Daniel Lezcano, Geert
Uytterhoeven, Hubert Jasudowicz, Tom Rix).

tools/power turbostat: harden against cpu hotplug
turbostat tends to get confused when CPUs are added and removed while it is running. There are races, such as checking the current cpu, and then reading a sysfs file that depends on that cpu number. Close the two issues that seem to come up the most. First, there is an infinite reset loop detector -- change that to allow more resets before giving up. Secondly, one of those file reads didn't really need to exit the program on failure... Signed-off-by: Len Brown <len.brown@intel.com> |

tools/power turbostat: adjust for temperature offset
cpu1: MSR_IA32_TEMPERATURE_TARGET: 0x05640000 (95 C) (100 default - 5 offset) Account for the new "offset" field in MSR_TEMPERATURE_TARGET. While this field is usually zero, ignoring it results in over-stating the current temperature, both per-core and per-package. Signed-off-by: Len Brown <len.brown@intel.com> |

tools/power x86_energy_perf_policy: Input/output error in a VM
I've encountered an issue with x86_energy_perf_policy. If I run it on a machine that I'm told is a qemu-kvm virtual machine running inside a privileged container, I get the following error: x86_energy_perf_policy: /dev/cpu/0/msr offset 0x1ad read failed: Input/output error I get the same error in a Digital Ocean droplet, so that might be a similar environment. I created the following patch which is intended to give a more user-friendly message. It's based on a patch for turbostat from Prarit Bhargava that was posted some time ago. The patch is "[v2] turbostat: Running on virtual machine is not supported" [1]. Given my limited knowledge of the topic, I can't say with confidence that this is the right solution, though (that's why this is not an official patch submission). Also, I'm not sure what the convention with exit codes is in this tool. Also, instead of the error message, perhaps the tool should just not print anything in this case, which is how it behaves in a "regular" VM?

tools/power turbostat: Skip pc8, pc9, pc10 columns, if they are disabled
Like we skip PC3 and PC6 columns when the package C-state limit disables them, skip PC8/PC9/CP10 under analogous conditions. Reported-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com> |

tools/power turbostat: Fix output formatting for ACPI CST enumeration
turbostat formatting is broken with ACPI CST for enumeration. The problem is that the CX_ACPI% is eight characters long which does not work with tab formatting. One simple solution is to remove the underbar from the state name such that C1_ACPI will be displayed as C1ACPI.

tools/power turbostat: Replace HTTP links with HTTPS ones: TURBOSTAT UTILITY
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

tools/power turbostat: Introduce functions to accumulate RAPL consumption
Since the RAPL Joule Counter is 32 bit, turbostat would only print a *star* instead of printing the actual energy consumed to indicate the overflow due to long duration. This does not meet the requirement from servers as the sampling time of turbostat is usually very long on servers. So maintain a set of MSR buffer, and update them periodically before the 32bit MSR register is wrapped round, so as to avoid the overflow. The idea is similar to the implementation of ktime_get(): Periodical MSR timer: total_rapl_sum += (current_rapl_msr - last_rapl_msr); Using get_msr_sum() to get the accumulated RAPL: return (current_rapl_msr - last_rapl_msr) + total_rapl_sum; The accumulated RAPL mechanism will be turned on in next patch.

tools/power turbostat: Always print idle in the system configuration header
If the --quiet option is not used, turbostat prints a useful system configuration header during startup. But inclusion of idle system configuration information in this header is currently a function of inclusion in the columns chosen to be displayed. Always list this idle system configuration.
