* | acpi/processor: Check for duplicate processor ids at hotplug timeDou Liyang2017-03-111-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The check for duplicate processor ids happens at boot time based on the ACPI table contents, but the final sanity checks for a processor happen at hotplug time. At hotplug time, where the physical information is available, which might differ from the ACPI table information, a check for duplicate processor ids is missing. Add it to the hotplug checks and rename the function so it better reflects its purpose.

* | acpi/processor: Implement DEVICE operator for processor enumerationDou Liyang2017-03-111-7/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ACPI allows to declare processors either with the PROCESSOR or with the DEVICE operator. The current implementation handles only the PROCESSOR operator. On a system which uses the DEVICE operator for processor enumeration the evaluation fails. Check for the ACPI type of the ACPI handle and evaluate PROCESSOR and DEVICE types separately.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | Revert: dc6db24d2476 ("x86/acpi: Set persistent cpuid <-> nodeid mapping when booting") The mapping of "cpuid <-> nodeid" is established at boot time via ACPI tables to keep associations of workqueues and other node related items consistent across cpu hotplug. But, ACPI tables are unreliable and failures with that boot time mapping have been reported on machines where the ACPI table and the physical information which is retrieved at actual hotplug is inconsistent. Revert the mapping implementation so it can be replaced with a less error prone approach.

| * x86/ioapic: Split IOAPIC hot-removal into two stepsRui Wang2017-03-013-8/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hot removal of IOAPIC is handling PCI and ACPI removal in one go. That only works when the PCI drivers released the interrupt resources, but breaks when a IOAPIC interrupt is still associated to a PCI device. The new pcibios_release_device() callback allows to solve that problem by splitting the removal into two steps: 1) PCI removal: Release all PCI resources including eventually not yet released IOAPIC interrupts via the new pcibios_release_device() callback. 2) ACPI removal: After release of all PCI resources the ACPI resources can be released without issue.

Details: - An "nvdimm namespace label" is metadata on an nvdimm that provisions dimm capacity into a "namespace" that can host a block device / dax-filesytem, or a device-dax character device. A namespace is an object that other operating environment and platform firmware needs to comprehend for capabilities like booting from an nvdimm. The label metadata contains a checksum that Linux was not calculating correctly leading to other environments rejecting the Linux label. These have received a build success notification from the kbuild robot, and a positive test result from Nick who reported the problem" * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: nfit, libnvdimm: fix interleave set cookie calculation tools/testing/nvdimm: make iset cookie predictable

The checksum is calculated by sorting the DIMMs by their location in the interleave-set. The comparison for the sort must be 64-bit wide, not byte-by-byte as performed by memcmp() in the broken case. Fix the implementation to accept correct cookie values in addition to the Linux "memcmp" order cookies, but only allow correct cookies to be generated going forward. It does mean that namespaces created by third-party-tooling, or created by newer kernels with this fix, will not validate on older kernels. However, there are a couple mitigating conditions: 1/ platforms with namespace-label capable NVDIMMs are not widely available. 2/ interleave-sets with a single-dimm are by definition not affected (nothing to sort). This covers the QEMU-KVM NVDIMM emulation case. The cookie stored in the namespace label will be fixed by any write the namespace label, the most straightforward way to achieve this is to write to the "alt_name" attribute of a namespace in sysfs.

This appears reasonable because BERT contents need to be non-volatile across reboot. But this will cause resources conflict in current Linux kernel implementation because the ACPI NVS area is marked as busy. The resource conflict is fixed via excluding the ACPI NVS area when requesting IO resources for BERT. When accessing the BERT contents, the whole BERT address range will be ioremapped and accessed.

Occasionally the BUSY bit in the Flag Register gets stuck as 1, erratum 44 for both 2432v1 and 2400v1 SoCs.Checking that the Transmit FIFO Empty (TXFE) bit is 0, instead of checking that the BUSY bit is 1, works around the issue. To facilitate this substitution of flags and values, introduce vendor-specific inversion of Feature Register bits when UART AMBA Port (UAP) data is available. For the earlycon case, prior to UAP availability, implement alternative putc and early_write functions. Similar to what how ARMv8 ACPI PCI quirks are detected during MCFG parsing, check the OEM fields of the Serial Port Console Redirection (SPCR) ACPI table to determine if the current platform is known to be affected by the erratum.

The iort_node_get_id() takes an index as input to refer to a specific mapping entry in the named component IORT node mapping array. For a mapping entry at a given index, iort_node_get_id() should return the id value (through the id_out function parameter) and the IORT node output_reference (through function return value) the given mapping entry refers to. Technically output_reference values may differ for different map entries, (see diagram below - mapped id values may refer to different eg IORT SMMU nodes; the kernel may not be able to handle different output_reference values for a given named component but the IORT kernel layer should still report the IORT mappings as reported by firmware) but current code in iort_node_get_id() fails to use the index function parameter to return the correct output_reference value (ie it always returns the output_reference value of the first entry in the mapping array whilst using the index correctly to retrieve the id value from the respective entry). |----------------------| | named component | |----------------------| | map entry[0] | |----------------------| | id value | | output_reference----------------> eg SMMU 1 |----------------------| | map entry[1] | |----------------------| | id value | | output_reference----------------> eg SMMU 2 |----------------------| . . . |----------------------| | map entry[N] | |----------------------| | id value | | output_reference----------------> eg SMMU 1 |----------------------| Consequently the iort_node_get_id() function always returns the IORT node pointed at by the output_reference value of the first named component mapping array entry, irrespective of the index parameter, which is a bug. Update the map array entry pointer computation in iort_node_get_id() to take into account the index value, fixing the issue.

This patch sets it the default behavior. If a platform doesn't send lid open event or lid open event is lost due to the underlying system problems, then we can compare various combinations: 1. systemd/acpid is used to suspend system or not, systemd has a special logic forcing open event after resuming; 2. _LID returns a cached value or not. The result is as follows: 1. lid_init_state=method 1. cached 1. resumed by lid: (x) event=close (x) systemd=suspends again (x) acpid=suspends again (x) state=close 2. resumed by other: (o) event=close (x) systemd=suspends again (x) acpid=suspends again (o) state=close 2. non-cached 1. resumed by lid: (o) event=open (o) systemd=resumes (o) acpid=resumes (o) state=open 2. resumed by other: (o) event=close (x) systemd=suspends again (x) acpid=suspends again (o) state=close 2. lid_init_state=open 1. cached 1. resumed by lid: (o) event=open (o) systemd=resumes (o) acpid=resumes (x) state=close 2. resumed by other: (x) event=open (o) systemd=resumes (o) acpid=resumes (o) state=close 2. non-cached 1. resumed by lid: (o) event=open (o) systemd=resumes (o) acpid=resumes (o) state=open 2. resumed by other: (x) event=open (o) systemd=resumes (o) acpid=resumes (o) state=close 3. lid_init_state=ignore 1. cached 1. resumed by lid: (o) event=none (x) systemd=suspends again (o) acpid=resumes (x) state=close 2. resumed by other: (o) event=none (x) systemd=suspends again (o) acpid=resumes (o) state=close 2. non-cached 1. resumed by lid: (o) event=none (x) systemd=suspends again (o) acpid=resumes (o) state=open 2. resumed by other: (o) event=none (x) systemd=suspends again (o) acpid=resumes (o) state=close As a conclusion: 1. With systemd changed, lid_init_state=ignore has only one problem and the problem comes from an underlying issue, not userspace and kernel lid handling. 2. Without systemd changed, lid_init_state=open can be the default behavior as the pass ratio is not much worse than lid_init_state=ignore. 3. lid_init_state=method is buggy, we can have a separate patch to make it deprectated.

Triggered by the following code, invoked from acpi_ec_enable_event(): if (!test_bit(EC_FLAGS_QUERY_PENDING, &ec->flags)) advance_transaction(ec); 2. Drained by the following code, invoked after acpi_ec_complete_query(): if (status & ACPI_EC_FLAG_SCI) acpi_ec_submit_query(ec); This facility is safer than the old CLEAR_ON_RESUME quirk as the CLEAR_ON_RESUME quirk sends EC query commands unconditionally. The behavior is apparently not suitable for firmware that requires QUERY_HANDSHAKE quirk. Though the QUERY_HANDSHAKE quirk isn't used now because of the improvement done in the EC transaction state machine (ec_event_clearing=QUERY), it is the proof that we cannot send EC query command unconditionally. So it's time to delete the out-dated CLEAR_ON_RESUME quirk to let the users to try the newer approach.
