ACPI ERST: support for ACPI ERST feature

2022-02-06T09:33:50+00:00

This implements a PCI device for ACPI ERST. This implements the non-NVRAM "mode" of operation for ERST as it is supported by Linux and Windows.

pci: introduce acpi-index property for PCI device

2021-03-22T22:58:19+00:00

In x86/ACPI world, linux distros are using predictable network interface naming since systemd v197. Which on QEMU based VMs results into path based naming scheme, that names network interfaces based on PCI topology. With itm on has to plug NIC in exactly the same bus/slot, which was used when disk image was first provisioned/configured or one risks to loose network configuration due to NIC being renamed to actually used topology. That also restricts freedom to reshape PCI configuration of VM without need to reconfigure used guest image. systemd also offers "onboard" naming scheme which is preferred over PCI slot/topology one, provided that firmware implements: " PCI Firmware Specification 3.1 4.6.7. DSM for Naming a PCI or PCI Express Device Under Operating Systems " that allows to assign user defined index to PCI device, which systemd will use to name NIC. For example, using -device e1000,acpi-index=100 guest will rename NIC to 'eno100', where 'eno' is default prefix for "onboard" naming scheme. This doesn't require any advance configuration on guest side to com in effect at 'onboard' scheme takes priority over path based naming. Hope is that 'acpi-index' it will be easier to consume by management layer, compared to forcing specific PCI topology and/or having several disk image templates for different topologies and will help to simplify process of spawning VM from the same template without need to reconfigure guest NIC. This patch adds, 'acpi-index'* property and wires up a 32bit register on top of pci hotplug register block to pass index value to AML code at runtime. Following patch will add corresponding _DSM code and wire it up to PCI devices described in ACPI. *) name comes from linux kernel terminology Signed-off-by: Igor Mammedov Message-Id: <20210315180102.3008391-3-imammedo@redhat.com> Reviewed-by: Michael S.

acpi: cpuhp: introduce 'firmware performs eject' status/control bits

2020-12-09T18:04:17+00:00

Adds bit #4 to status/control field of CPU hotplug MMIO interface. New bit will be used OSPM to mark CPUs as pending for removal by firmware, when it calls _EJ0 method on CPU device node. Later on, when firmware sees this bit set, it will perform CPU eject which will clear bit #4 as well.

acpi: cpuhp: introduce 'Command data 2' field

2020-01-22T05:23:07+00:00

No functional change in practice, patch only aims to properly document (in spec and code) intended usage of the reserved space. The new field is to be used for 2 purposes: - detection of modern CPU hotplug interface using CPHP_GET_NEXT_CPU_WITH_EVENT_CMD command. procedure will be described in follow up patch: "acpi: cpuhp: spec: add typical usecases" - for returning upper 32 bits of architecture specific CPU ID, for new CPHP_GET_CPU_ID_CMD command added by follow up patch: "acpi: cpuhp: add CPHP_GET_CPU_ID_CMD command" Change is backward compatible with 4.2 and older machines, as field was unconditionally reserved and always returned 0x0 if modern CPU hotplug interface was enabled.

2019-03-22T16:18:07+00:00

We spell out sub/dir/ in sub/dir/trace-events' comments pointing to source files. That's because when trace-events got split up, the comments were moved verbatim. Delete the sub/dir/ part from these comments. Gets rid of several misspellings.
