2022-10-05mailbox: mpfs: account for mbox offsets while sendingConor Dooley1-4/+3
The mailbox offset is not only used for receiving messages, but it is also used by messages sent to the system controller by Linux that have a payload, such as the "digital signature service". It is also overloaded by certain other services (reprogramming of the FPGA fabric, see Link:) to have a meaning other than the offset the system controller should read from. When the driver was written, no such services of the latter type were in use & those of the former used an offset of zero so this has gone un-noticed.

2022-10-05i2c: designware: Fix handling of real but unexpected device interruptsJarkko Nikula2-2/+18
Commit c7b79a752871 ("mfd: intel-lpss: Add Intel Alder Lake PCH-S PCI IDs") caused a regression on certain Gigabyte motherboards for Intel Alder Lake-S where system crashes to NULL pointer dereference in i2c_dw_xfer_msg() when system resumes from S3 sleep state ("deep"). I was able to debug the issue on Gigabyte Z690 AORUS ELITE and made following notes: - Issue happens when resuming from S3 but not when resuming from "s2idle" - PCI device 00:15.0 == i2c_designware.0 is already in D0 state when system enters into pci_pm_resume_noirq() while all other i2c_designware PCI devices are in D3. Devices were runtime suspended and in D3 prior entering into suspend - Interrupt comes after pci_pm_resume_noirq() when device interrupts are re-enabled - According to register dump the interrupt really comes from the i2c_designware.0. Controller is enabled, I2C target address register points to a one detectable I2C device address 0x60 and the DW_IC_RAW_INTR_STAT register START_DET, STOP_DET, ACTIVITY and TX_EMPTY bits are set indicating completed I2C transaction. My guess is that the firmware uses this controller to communicate with an on-board I2C device during resume but does not disable the controller before giving control to an operating system. I was told the UEFI update fixes this but never the less it revealed the driver is not ready to handle TX_EMPTY (or RX_FULL) interrupt when device is supposed to be idle and state variables are not set (especially the dev->msgs pointer which may point to NULL or stale old data). Introduce a new software status flag STATUS_ACTIVE indicating when the controller is active in driver point of view. Now treat all interrupts that occur when is not set as unexpected and mask all interrupts from the controller.

2022-10-05PCI: Expose PCIe Resizable BAR support via sysfsAlex Williamson1-0/+108
Add a simple sysfs interface to Resizable BAR support, largely for the purposes of assigning such devices to a VM through VFIO. Resizable BARs present a difficult feature to expose to a VM through emulation, as resizing a BAR is done on the host. It can fail, and often does, but we have no means via emulation of a PCIe REBAR capability to handle the error cases. A vfio-pci specific ioctl interface is also cumbersome as there are often multiple devices within the same bridge aperture and handling them is a challenge. In the interface proposed here, expanding a BAR potentially requires such devices to be soft-removed during the resize operation and rescanned after, in order for all the necessary resources to be released. A pci-sysfs interface is also more universal than a vfio specific interface. Please see the ABI documentation update for usage.

2022-10-05PCI/ASPM: Correct LTR_L1.2_THRESHOLD computationBjorn Helgaas1-17/+32
80d7d7a904fa ("PCI/ASPM: Calculate LTR_L1.2_THRESHOLD from device characteristics") replaced a fixed value (163840ns) with one computed from T_POWER_OFF, Common_Mode_Restore_Time, etc., but it encoded the LTR_L1.2_THRESHOLD value incorrectly. This is especially a problem for small thresholds, e.g., 63ns fell into the "threshold_ns < 1024" case and was encoded as 32ns: LTR_L1.2_THRESHOLD_Scale = 1 (multiplier is 32ns) LTR_L1.2_THRESHOLD_Value = 63 >> 5 = 1 LTR_L1.2_THRESHOLD = multiplier * value = 32ns * 1 = 32ns Correct the algorithm to encode all times of 1023ns (0x3ff) or smaller exactly and larger times conservatively (the encoded threshold is never smaller than was requested). This reduces the chance of entering L1.2 when the device can't tolerate the exit latency.

187f91db8237 ("PCI/ASPM: Remove struct aspm_register_info.l1ss_cap") inadvertently removed a check for existence of the L1 PM Substates (L1SS) Capability before reading it. If there is no L1SS Capability, this means we mistakenly read PCI_COMMAND and PCI_STATUS (config address 0x04) and interpret that as the PCI_L1SS_CAP register, so we may incorrectly configure L1SS. Make sure the L1SS Capability exists before trying to read it.

If X86_AMD_PSTATE is set disabled, it can tell the users test can only run on amd-pstate driver, please set X86_AMD_PSTATE enabled. In the future, comparison tests will be added. It can set amd-pstate disabled and set acpi-cpufreq enabled to run test cases, then compare the test results.
