2021-04-19perf/x86: Hybrid PMU support for countersKan Liang
The number of GP and fixed counters are different among hybrid PMUs. Each hybrid PMU should use its own counter related information. When handling a certain hybrid PMU, apply the number of counters from the corresponding hybrid PMU. When reserving the counters in the initialization of a new event, reserve all possible counters. The number of counter recored in the global x86_pmu is for the architecture counters which are available for all hybrid PMUs. KVM doesn't support the hybrid PMU yet. Return the number of the architecture counters for now. For the functions only available for the old platforms, e.g., intel_pmu_drain_pebs_nhm(), nothing is changed.

2021-04-19perf/x86: Hybrid PMU support for intel_ctrlKan Liang
The intel_ctrl is the counter mask of a PMU. The PMU counter information may be different among hybrid PMUs, each hybrid PMU should use its own intel_ctrl to check and access the counters. When handling a certain hybrid PMU, apply the intel_ctrl from the corresponding hybrid PMU. When checking the HW existence, apply the PMU and number of counters from the corresponding hybrid PMU as well. Perf will check the HW existence for each Hybrid PMU before registration. Expose the check_hw_exists() for a later patch.

2021-04-19perf/x86/intel: Hybrid PMU support for perf capabilitiesKan Liang
Some platforms, e.g. Alder Lake, have hybrid architecture. Although most PMU capabilities are the same, there are still some unique PMU capabilities for different hybrid PMUs. Perf should register a dedicated pmu for each hybrid PMU. Add a new struct x86_hybrid_pmu, which saves the dedicated pmu and capabilities for each hybrid PMU. The architecture MSR, MSR_IA32_PERF_CAPABILITIES, only indicates the architecture features which are available on all hybrid PMUs. The architecture features are stored in the global x86_pmu.intel_cap. For Alder Lake, the model-specific features are perf metrics and PEBS-via-PT. The corresponding bits of the global x86_pmu.intel_cap should be 0 for these two features. Perf should not use the global intel_cap to check the features on a hybrid system. Add a dedicated intel_cap in the x86_hybrid_pmu to store the model-specific capabilities. Use the dedicated intel_cap to replace the global intel_cap for thse two features. The dedicated intel_cap will be set in the following "Add Alder Lake Hybrid support" patch. Add is_hybrid() to distinguish a hybrid system. ADL may have an alternative configuration. With that configuration, the X86_FEATURE_HYBRID_CPU is not set. Perf cannot rely on the feature bit. Add a new static_key_false, perf_is_hybrid, to indicate a hybrid system. It will be assigned in the following "Add Alder Lake Hybrid support" patch as well.

2021-04-19perf/x86: Track pmu in per-CPU cpu_hw_eventsKan Liang
Some platforms, e.g. Alder Lake, have hybrid architecture. In the same package, there may be more than one type of CPU. The PMU capabilities are different among different types of CPU. Perf will register a dedicated PMU for each type of CPU. Add a 'pmu' variable in the struct cpu_hw_events to track the dedicated PMU of the current CPU. Current x86_get_pmu() use the global 'pmu', which will be broken on a hybrid platform. Modify it to apply the 'pmu' of the specific CPU. Initialize the per-CPU 'pmu' variable with the global 'pmu'. There is nothing changed for the non-hybrid platforms. The is_x86_event() will be updated in the later patch ("perf/x86: Register hybrid PMUs") for hybrid platforms. For the non-hybrid platforms, nothing is changed here.

2021-04-19x86/cpu: Add helper function to get the type of the current hybrid CPURicardo Neri
On processors with Intel Hybrid Technology (i.e., one having more than one type of CPU in the same package), all CPUs support the same instruction set and enumerate the same features on CPUID. Thus, all software can run on any CPU without restrictions. However, there may be model-specific differences among types of CPUs. For instance, each type of CPU may support a different number of performance counters. Also, machine check error banks may be wired differently. Even though most software will not care about these differences, kernel subsystems dealing with these differences must know. Add and expose a new helper function get_this_hybrid_cpu_type() to query the type of the current hybrid CPU. The function will be used later in the perf subsystem. The Intel Software Developer's Manual defines the CPU type as 8-bit identifier.

2021-04-19x86/cpufeatures: Enumerate Intel Hybrid Technology feature bitRicardo Neri
Add feature enumeration to identify a processor with Intel Hybrid Technology: one in which CPUs of more than one type are the same package. On a hybrid processor, all CPUs support the same homogeneous (i.e., symmetric) instruction set. All CPUs enumerate the same features in CPUID. Thus, software (user space and kernel) can run and migrate to any CPU in the system as well as utilize any of the enumerated features without any change or special provisions. The main difference among CPUs in a hybrid processor are power and performance properties.

2021-04-19IB/ipoib: Improve latency in ipoib/cm connection formationManjunath Patil
Currently IPoIB connected mode queries the device to get the pkey table entry during connection formation. This will increase the time taken to form the connection, especially when limited pkeys are in use. This gets worse when multiple connection attempts are done in parallel. Since ipoib interfaces are locked to a single pkey, use the pkey index that was determined at link up time instead of searching for anything. This improved the latency from 500ms to 1ms on an internal setup.

2021-04-19Merge series "ASoC: rt286/rt298: Fixes for DMIC2 config and combo jack" from ↵Mark Brown
David Ward <david.ward@gatech.edu>: The last two patches in this series fix a longstanding issue that prevented the ALC3263 codec from using a headset mic. This codec can be found on Dell systems including the Latitude 13 7350, Venue 11 Pro 7140, and XPS 13 9343. In fact, there is an ACPI quirk for the XPS 13 9343, which forces it to use legacy HD Audio just to avoid this issue: https://lore.kernel.org/alsa-devel/CAPeXnHv07HkvcHrYFmZMr8OTp7U7F=k_k=LPYnUtp89iPn2d2Q@mail.gmail.com/ This may allow that ACPI quirk to be removed. Either way, the other systems mentioned above do not support this quirk and already use the ASoC driver, so this fix is necessary for headset mic support on those systems. Note: there is likely other handling for this codec that only exists in the HDA driver, but which also belongs in the ASoC driver. Commit 394c97f824fa ("ALSA: hda/realtek - Change EAPD to verb control") describes an issue that does not seem to be resolved in the ASoC driver, to give an example. Other patches in this series are not specific to the ALC3263. These patches set the correct combo jack configuration when headphones are inserted, and fix a misaligned value set in the DMIC2 Configuration Default register.

2021-04-19ASoC: rt286: Generalize support for ALC3263 codecDavid Ward
The ALC3263 codec on the XPS 13 9343 is also found on the Latitude 13 7350 and Venue 11 Pro 7140. They require the same handling for the combo jack to work with a headset: GPIO pin 6 must be set. The HDA driver always sets this pin on the ALC3263, which it distinguishes by the codec vendor/device ID 0x10ec0288 and PCI subsystem vendor ID 0x1028 (Dell). The ASoC driver does not use PCI, so adapt this check to use DMI to determine if Dell is the system vendor.

The ALSA control readback functionality only works for non-volatile controls, i.e. control values that does not change on their own without driver interaction. This doesn't work for readbacks since the DSP firmware updates the control value. Disable the cache mechanism in the driver if the control name matches the prefix used for readbacks to ensure that the control value is valid.

2021-04-19ALSA: usb-audio: Re-apply implicit feedback mode to Pioneer devicesTakashi Iwai
Pioneer devices are supposed to be working with the implicit feedback mode, but so far the attempt to apply the implicit feedback caused issues, hence we explicitly skipped the implicit feedback mode for them. Recently, Geraldo discovered that the device actually works if you skip the generic matching of the sync EPs for the capture stream. That is, we should apply the implicit feedback setup for the playback like other similar devices, while we need to return 1 from audioformat_capture_quirk() so that no further matching will be done. And, later on, Olivia reported later that the fiddling with the capture quirk alone doesn't suffice for the test with speaker-test program. This seems to be a similar case like the recently fixed BOSS devices. Indeed, the problem could be addressed by setting playback_first flag, which indicates that the playback URBs have to be sent out at first even in the implicit feedback mode. This patch implements the application of the implicit feedback to Pioneer devices as described in the above. The former skip_pioneer_sync_ep() was dropped, and instead we provide is_pioneer_implicit_fb() to check the Pioneer devices that need the implicit feedback. In the audioformat_implicit_fb_quirk(), simply apply the implicit fb for playback and set chip->playback_first flag if matching, and in audioformat_capture_quirk()(), it returns 1 for skipping the generic EP sync handling.
