* ACPI: memhotplug: use a single static memory group for a single memory deviceDavid Hildenbrand2021-09-081-5/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's group all memory we add for a single memory device - we want a single node for that (which also seems to be the sane thing to do). We won't care for now about memory that was already added to the system (e.g., via e820) -- usually *all* memory of a memory device was already added and we'll fail acpi_memory_enable_device().

* mm/memory_hotplug: remove nid parameter from remove_memory() and friendsDavid Hildenbrand2021-09-081-6/+1

We can simply lookup the nid only used for node offlining purposes when walking our memory blocks. We don't expect to remove multi-nid ranges; and if we'd ever do, we most probably don't care about removing multi-nid ranges that actually result in empty nodes. If ever required, we can detect the "multi-nid" scenario and simply try offlining all online nodes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the NFIT parsing code to treat a 0 index in a SPA Range Structure as a special case and not match Region Mapping Structures that use 0 to indicate that they are not mapped. Without this fix some platform BIOS descriptions of "virtual disk" ranges do not result in the pmem driver attaching to the range. Details: In addition to typical persistent memory ranges, the ACPI NFIT may also convey "virtual" ranges. These ranges are indicated by a UUID in the SPA Range Structure of UUID_VOLATILE_VIRTUAL_DISK, UUID_VOLATILE_VIRTUAL_CD, UUID_PERSISTENT_VIRTUAL_DISK, or UUID_PERSISTENT_VIRTUAL_CD. The critical difference between virtual ranges and UUID_PERSISTENT_MEMORY, is that virtual do not support associations with Region Mapping Structures. For this reason the "index" value of virtual SPA Range Structures is allowed to be 0. If a platform BIOS decides to represent NVDIMMs with disconnected "Region Mapping Structures" (range-index == 0), the kernel may falsely associate them with standalone ranges where the "SPA Range Structure Index" is also zero. When this happens the driver may falsely require labels where "virtual disks" are expected to be label-less. I.e. "label-less" is where the namespace-range == region-range and the pmem driver attaches with no user action to create a namespace.

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current assumption that methods to read PCH FIVR attributes will return integer, is not correct. There is no good way to return integer as negative numbers are also valid. These read methods return a package of integers. The first integer returns status, which is 0 on success and any other value for failure. When the returned status is zero, then the second integer returns the actual value. This change fixes this issue by replacing acpi_evaluate_integer() with acpi_evaluate_object() and use acpi_extract_package() to extract results.

These events only occur when the EC GPE is inadvertently set as a wakeup source. Originally the EC GPE was only set as a wakeup source when using the intel-vbtn or intel-hid drivers in commit 10a08fd65ec1 ("ACPI: PM: Set up EC GPE for system wakeup from drivers that need it") but during testing a reporter discovered that this was not enough for their ASUS Zenbook UX430UNR/i7-8550U to wakeup by lid event or keypress. Marking the EC GPE for wakeup universally resolved this for that reporter in commit b90ff3554aa3 ("ACPI: PM: s2idle: Always set up EC GPE for system wakeup"). However this behavior has lead to a number of problems: * On both Lenovo T14 and P14s the keyboard wakeup doesn't work, and sometimes the power button event doesn't work. * On HP 635 G7 detaching or attaching AC during suspend will cause the system not to wakeup * On Asus vivobook to prevent detaching AC causing resume problems * On Lenovo 14ARE05 to prevent detaching AC causing resume problems * On HP ENVY x360 to prevent detaching AC causing resume problems As there may be other Intel systems besides ASUS Zenbook UX430UNR/i7-8550U that don't use intel-vbtn or intel-hid, avoid these problems by only universally marking the EC GPE wakesource on non-AMD systems.

For now it describes the relation between virtio-iommu and the endpoints it manages. Three steps are needed to configure DMA of endpoints: (1) acpi_viot_init(): parse the VIOT table, find or create the fwnode associated to each vIOMMU device. This needs to happen after acpi_scan_init(), because it relies on the struct device and their fwnode to be available. (2) When probing the vIOMMU device, the driver registers its IOMMU ops within the IOMMU subsystem. This step doesn't require any intervention from the VIOT driver. (3) viot_iommu_configure(): before binding the endpoint to a driver, find the associated IOMMU ops. Register them, along with the endpoint ID, into the device's iommu_fwspec. If step (3) happens before step (2), it is deferred until the IOMMU is initialized, then retried.

This is "typically" accomplished using the `StorageD3Enable` property in the _DSD, but this property was introduced after many of these systems launched and most OEM systems don't have it in their BIOS. On AMD Renoir without these drives going into D3 over suspend-to-idle the resume will fail with the NVME controller being reset and a trace like this in the kernel logs: ``` [ 83.556118] nvme nvme0: I/O 161 QID 2 timeout, aborting [ 83.556178] nvme nvme0: I/O 162 QID 2 timeout, aborting [ 83.556187] nvme nvme0: I/O 163 QID 2 timeout, aborting [ 83.556196] nvme nvme0: I/O 164 QID 2 timeout, aborting [ 95.332114] nvme nvme0: I/O 25 QID 0 timeout, reset controller [ 95.332843] nvme nvme0: Abort status: 0x371 [ 95.332852] nvme nvme0: Abort status: 0x371 [ 95.332856] nvme nvme0: Abort status: 0x371 [ 95.332859] nvme nvme0: Abort status: 0x371 [ 95.332909] PM: dpm_run_callback(): pci_pm_resume+0x0/0xe0 returns -16 [ 95.332936] nvme 0000:03:00.0: PM: failed to resume async: error -16 ``` The Microsoft documentation for StorageD3Enable mentioned that Windows has a hardcoded allowlist for D3 support, which was used for these platforms. Introduce quirks to hardcode them for Linux as well. As this property is now "standardized", OEM systems using AMD Cezanne and newer APU's have adopted this property, and quirks like this should not be necessary.
