2022-03-16thermal: int340x: Update OS policy capability handshakeSrinivas Pandruvada
Update the firmware with OS supported policies mask, so that firmware can relinquish its internal controls. Without this update several Tiger Lake laptops gets performance limited with in few seconds of executing in turbo region. The existing way of enumerating firmware policies via IDSP method and selecting policy by directly writing those policy UUIDS via _OSC method is not supported in newer generation of hardware. There is a new UUID "B23BA85D-C8B7-3542-88DE-8DE2FFCFD698" is defined for updating policy capabilities. As part of ACPI _OSC method: Arg0 - UUID: B23BA85D-C8B7-3542-88DE-8DE2FFCFD698 Arg1 - Rev ID: 1 Arg2 - Count: 2 Arg3 - Capability buffers: Array of Arg2 DWORDS DWORD1: As defined in the ACPI 5.0 Specification - Bit 0: Query Flag - Bits 1-3: Always 0 - Bits 4-31: Reserved DWORD2 and beyond: - Bit0: set to 1 to indicate Intel(R) Dynamic Tuning is active, 0 to indicate it is disabled and legacy thermal mechanism should be enabled. - Bit1: set to 1 to indicate Intel(R) Dynamic Tuning is controlling active cooling, 0 to indicate bios shall enable legacy thermal zone with active trip point. - Bit2: set to 1 to indicate Intel(R) Dynamic Tuning is controlling passive cooling, 0 to indicate bios shall enable legacy thermal zone with passive trip point. - Bit3: set to 1 to indicate Intel(R) Dynamic Tuning is handling critical trip point, 0 to indicate bios shall enable legacy thermal zone with critical trip point. - Bits 4:31: Reserved From sysfs interface, there is an existing interface to update policy UUID using attribute "current_uuid". User space can write the same UUID for ACTIVE, PASSIVE and CRITICAL policy. Driver converts these UUIDs to DWORD2 Bit 1 to Bit 3. When any of the policy is activated by user space it is assumed that dynamic tuning is active. For example $cd /sys/bus/platform/devices/INTC1040:00/uuids To support active policy $echo "3A95C389-E4B8-4629-A526-C52C88626BAE" > current_uuid To support passive policy $echo "42A441D6-AE6A-462b-A84B-4A8CE79027D3" > current_uuid To support critical policy $echo "97C68AE7-15FA-499c-B8C9-5DA81D606E0A" > current_uuid To check all the supported policies $cat current_uuid 3A95C389-E4B8-4629-A526-C52C88626BAE 42A441D6-AE6A-462b-A84B-4A8CE79027D3 97C68AE7-15FA-499c-B8C9-5DA81D606E0A To match the bit format for DWORD2, rearranged enum int3400_thermal_uuid and int3400_thermal_uuids[] by swapping current INT3400_THERMAL_ACTIVE and INT3400_THERMAL_PASSIVE_1. If the policies are enumerated via IDSP method then legacy method is used, if not the new method is used to update policy support.

2022-03-16PM: hibernate: Honour ACPI hardware signature by default for virtual guestsDavid Woodhouse
The ACPI specification says that OSPM should refuse to restore from hibernate if the hardware signature changes, and should boot from scratch. However, real BIOSes often vary the hardware signature in cases where we *do* want to resume from hibernate, so Linux doesn't follow the spec by default. However, in a virtual environment there's no reason for the VMM to vary the hardware signature *unless* it wants to trigger a clean reboot as defined by the ACPI spec. So enable the check by default if a hypervisor is detected. Signed-off-by: David Woodhouse <dwmw@amazon.co.uk> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
2022-03-16cpufreq: intel_pstate: Use firmware default EPPSrinivas Pandruvada
For some specific platforms (E.g. AlderLake) the balance performance EPP is updated from the hard coded value in the driver. This acts as the default and balance_performance EPP. The purpose of this EPP update is to reach maximum 1 core turbo frequency (when possible) out of the box. Although we can achieve the objective by using hard coded value in the driver, there can be other EPP which can be better in terms of power. But that will be very subjective based on platform and use cases. This is not practical to have a per platform specific default hard coded in the driver. If a platform wants to specify default EPP, it can be set in the firmware. If this EPP is not the chipset default of 0x80 (balance_perf_epp unless driver changed it) and more performance oriented but not 0, the driver can use this as the default and balanced_perf EPP. In this case no driver update is required every time there is some new platform and default EPP. If the firmware didn't update the EPP from the chipset default then the hard coded value is used as per existing implementation.

2022-03-16ice: add trace events for tx timestampsJacob Keller
We've previously run into many issues related to the latency of a Tx timestamp completion with the ice hardware. It can be difficult to determine the root cause of a slow Tx timestamp. To aid in this, introduce new trace events which capture timing data about when the driver reaches certain points while processing a transmit timestamp * ice_tx_tstamp_request: Trace when the stack initiates a new timestamp request. * ice_tx_tstamp_fw_req: Trace when the driver begins a read of the timestamp register in the work thread. * ice_tx_tstamp_fw_done: Trace when the driver finishes reading a timestamp register in the work thread. * ice_tx_tstamp_complete: Trace when the driver submits the skb back to the stack with a completed Tx timestamp. These trace events can be enabled using the standard trace event subsystem exposed by the ice driver. If they are disabled, they become no-ops with no run time cost. The following is a simple GNU AWK script which can highlight one potential way to use the trace events to capture latency data from the trace buffer about how long the driver takes to process a timestamp: ----- BEGIN { PREC=256 } # Detect requests /tx_tstamp_request/ { time=strtonum($4) skb=$7 # Store the time of request for this skb requests[skb] = time printf("skb %s: idx %d at %.6f\n", skb, idx, time) } # Detect completions /tx_tstamp_complete/ { time=strtonum($4) skb=$7 idx=$9 if (skb in requests) { latency = (time - requests[skb]) * 1000 printf("skb %s: %.3f to complete\n", skb, latency) if (latency > 4) { printf(">>> HIGH LATENCY <<<\n") } printf("\n") } else { printf("!!! skb %s (idx %d) at %.6f\n", skb, idx, time) } } ----- Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Tested-by: Gurucharan <gurucharanx.g@intel.com> (A Contingent worker at Intel) Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>

Since there are no HT & VHT IEs being sent in 6ghz, some capabilities judgement and parsing for wtbl & starec configuration should be modified to reflect such changes.

2022-03-16mt76: fix monitor mode crash with sdio driverDeren Wu
mt7921s driver may receive frames with fragment buffers. If there is a CTS packet received in monitor mode, the payload is 10 bytes only and need 6 bytes header padding after RXD buffer. However, only RXD in the first linear buffer, if we pull buffer size RXD-size+6 bytes with skb_pull(), that would trigger "BUG_ON(skb->len < skb->data_len)" in __skb_pull(). To avoid the nonlinear buffer issue, enlarge the RXD size from 128 to 256 to make sure all MCU operation in linear buffer. [ 52.007562] kernel BUG at include/linux/skbuff.h:2313!
