git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Will Deacon: "The changes are a real mixed bag this time around. The only scary looking one from the diffstat is the uapi change to asm-generic/mman-common.h, but this has been acked by Arnd and is actually just adding a pair of comments in an attempt to prevent allocation of some PROT values which tend to get used for arch-specific purposes. We'll be using them for Branch Target Identification (a CFI-like hardening feature), which is currently under review on the mailing list. New architecture features: - Support for Armv8.5 E0PD, which benefits KASLR in the same way as KPTI but without the overhead. This allows KPTI to be disabled on CPUs that are not affected by Meltdown, even is KASLR is enabled. - Initial support for the Armv8.5 RNG instructions, which claim to provide access to a high bandwidth, cryptographically secure hardware random number generator. As well as exposing these to userspace, we also use them as part of the KASLR seed and to seed the crng once all CPUs have come online. - Advertise a bunch of new instructions to userspace, including support for Data Gathering Hint, Matrix Multiply and 16-bit floating point. Kexec: - Cleanups in preparation for relocating with the MMU enabled - Support for loading crash dump kernels with kexec_file_load() Perf and PMU drivers: - Cleanups and non-critical fixes for a couple of system PMU drivers FPU-less (aka broken) CPU support: - Considerable fixes to support CPUs without the FP/SIMD extensions, including their presence in heterogeneous systems. Good luck finding a 64-bit userspace that handles this. Modern assembly function annotations: - Start migrating our use of ENTRY() and ENDPROC() over to the new-fangled SYM_{CODE,FUNC}_{START,END} macros, which are intended to aid debuggers Kbuild: - Cleanup detection of LSE support in the assembler by introducing 'as-instr' - Remove compressed Image files when building clean targets IP checksumming: - Implement optimised IPv4 checksumming routine when hardware offload is not in use. An IPv6 version is in the works, pending testing. Hardware errata: - Work around Cortex-A55 erratum #1530923 Shadow call stack: - Work around some issues with Clang's integrated assembler not liking our perfectly reasonable assembly code - Avoid allocating the X18 register, so that it can be used to hold the shadow call stack pointer in future ACPI: - Fix ID count checking in IORT code. This may regress broken firmware that happened to work with the old implementation, in which case we'll have to revert it and try something else - Fix DAIF corruption on return from GHES handler with pseudo-NMIs Miscellaneous: - Whitelist some CPUs that are unaffected by Spectre-v2 - Reduce frequency of ASID rollover when KPTI is compiled in but inactive - Reserve a couple of arch-specific PROT flags that are already used by Sparc and PowerPC and are planned for later use with BTI on arm64 - Preparatory cleanup of our entry assembly code in preparation for moving more of it into C later on - Refactoring and cleanup" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (73 commits) arm64: acpi: fix DAIF manipulation with pNMI arm64: kconfig: Fix alignment of E0PD help text arm64: Use v8.5-RNG entropy for KASLR seed arm64: Implement archrandom.h for ARMv8.5-RNG arm64: kbuild: remove compressed images on 'make ARCH=arm64 (dist)clean' arm64: entry: Avoid empty alternatives entries arm64: Kconfig: select HAVE_FUTEX_CMPXCHG arm64: csum: Fix pathological zero-length calls arm64: entry: cleanup sp_el0 manipulation arm64: entry: cleanup el0 svc handler naming arm64: entry: mark all entry code as notrace arm64: assembler: remove smp_dmb macro arm64: assembler: remove inherit_daif macro ACPI/IORT: Fix 'Number of IDs' handling in iort_id_map() mm: Reserve asm-generic prot flags 0x10 and 0x20 for arch use arm64: Use macros instead of hard-coded constants for MAIR_EL1 arm64: Add KRYO{3,4}XX CPU cores to spectre-v2 safe list arm64: kernel: avoid x18 in __cpu_soft_restart arm64: kvm: stop treating register x18 as caller save arm64/lib: copy_page: avoid x18 register in assembler code ...

2020-01-27thermal: stm32: Fix low threshold interrupt floodPascal Paillet
With the STM32 thermal peripheral, it is not possible to dump the temperature that has caused the interrupt. When the temperature reaches the low threshold, we generally read a temperature that is a little bit higher than the low threshold. This maybe due to sampling precision, and also because the CPU becomes hotter when it quits WFI mode. In that case, the framework does not change the trip points. This leads to a lot of low threshold interrupts. The fix is to set the low threshold value 0.5 degrees Celsius below the actual request. The problem is not so frequent with the high threshold and it would no be a good idea to set the threshold value higher than the request.

2020-01-27thermal: of: Make thermal_zone_of_sensor_register return -ENODEV if a sensor ↵Peter Mamonov
OF node is missing When devm_thermal_zone_of_sensor_register() is called from hwmon_thermal_add_sensor() it is possible that the relevant sensor is missing an OF node. In this case thermal_zone_of_sensor_register() returns -EINVAL which causes hwmon_thermal_add_sensor() to fail as well. This patch changes relevant return code of thermal_zone_of_sensor_register() to -ENODEV, which is tolerated by hwmon_thermal_add_sensor(). Here is a particular case of such behaviour: the Marvell ethernet PHYs driver registers hwmon device for the built-in temperature sensor (see drivers/net/phy/marvell.c). Since the sensor doesn't have associated OF node devm_hwmon_device_register() returns error which ultimately causes failure of the PHY driver's probe function.

Michal Kalderon says: ==================== qed*: Utilize FW 8.42.2.0 This FW contains several fixes and features, main ones listed below. We have taken into consideration past comments on previous FW versions that were uploaded and tried to separate this one to smaller patches to ease review. - RoCE - SRIOV support - Fixes in following flows: - latency optimization flow for inline WQEs - iwarp OOO packed DDPs flow - tx-dif workaround calculations flow - XRC-SRQ exceed cache num - iSCSI - Fixes: - iSCSI TCP out-of-order handling. - iscsi retransmit flow - Fcoe - Fixes: - upload + cleanup flows - Debug - Better handling of extracting data during traffic - ILT Dump -> dumping host memory used by chip - MDUMP -> collect debug data on system crash and extract after reboot Patches prefixed with FW 8.42.2.0 are required to work with binary 8.42.2.0 FW where as the rest are FW related but do not require the binary. Changes from V2 --------------- - Move FW version to the start of the series to maintain minimal compatibility - Fix some kbuild errors: - frame size larger than 1024 (Queue Manager patch - remove redundant field from struct) - sparse warning on endianity (Dmae patch fix - wrong use of __le32 for field used only on host, should be u32) - static should be used for some functions (Debug feature ilt and mdump) Reported-by: kbuild test robot <lkp@intel.com> Changes from V1 --------------- - Remove epoch + kernel version from device debug dump - don't bump driver version ==================== Signed-off-by: David S.

Add to debug dump more information on the platform it was collected from (pci func, path id). Provide human readable reg fifo erros. Removed static debug arrays from HSI Functions, and move them to the hwfn. Some structures were slightly changed (removing reserved chip id for example) which lead to many long initializations being modified with one parameter less during initialization. This leads to some long diffs that don't really change anything.

2020-01-27qed: rt init valid initialization changedMichal Kalderon
The QM phase init tool can be invoked multiple times during the driver lifetime. Part of the init comes from the runtime array. The logic for setting the values did not init all values, basically assuming the runtime array was all zeroes. But if it was invoked multiple times, nobody was zeroing it after the first time. In this change we zero the runtime array right after using it.

The number of BTB blocks was modified to be different between the two chip flavors supported (BB/K2) as a result, this lead to a re-write of selecting the default hsi value based on the chip.

2020-01-27qed: FW 8.42.2.0 Additional ll2 typeMichal Kalderon
LL2 queues were a limited resource due to FW constraints. This FW introduced a new resource which is a context based ll2 queue (memory on host). The additional ll2 queues are required for RDMA SRIOV. The code refers to the previous ll2 queues as ram-based or legacy, and the new queues as ctx-based. This change decreased the "legacy" ram-based queues therefore the first ll2 queue used for iWARP was converted to the ctx-based ll2 queue. This feature also exposed a bug in the DIRECT_REG_WR64 macro implementation which didn't have an effect in other use cases.

There are several wide-bus registers written to by the fw_funcs that require using the dmae for atomicity. Therefore using the dmae channel functionality was added to the fw_funcs file, since the code is very similar to the previously used code, the structures used were moved to qed_hsi. Due to FW conventions, the names of the flags in the struct changed. Since this required slight modification in the places that set the flags the code was modified to use GET/SET FIELD macros.

Each of the PF's functionality is determined by what kind of resources are attached to it. If NPA and NIX blocks are attached to a PF it can function as a highly capable network device. This patch series add a network driver for the PF. Initial set of patches adds mailbox communication with admin function (RVU AF) and configuration of queues. Followed by Rx and tx pkts NAPI handler and then support for HW offloads like RSS, TSO, Rxhash etc. Ethtool support to extract stats, config RSS, queue sizes, queue count is also added.

2020-01-27octeontx2-pf: Error handling supportGeetha sowjanya
HW reports many errors on the receive and transmit paths. Such as incorrect queue configuration, pkt transmission errors, LMTST instruction errors, transmit queue full etc. These are reported via QINT interrupt. Most of the errors are fatal and needs reinitialization. Also added support to allocate receive buffers in non-atomic context when allocation fails in NAPI context.

2020-01-27octeontx2-pf: Register and handle link notificationsLinu Cherian
PF and AF (admin function) shares 64KB of reserved memory region for communication. This region is shared for - Messages sent by PF and responses sent by AF. - Notifications sent by AF and ACKs sent by PF. This patch adds infrastructure to handle notifications sent by AF and adds handlers to process them. One of the main usecase of notifications from AF is physical link changes. So this patch adds registration of PF with AF to receive link status change notifications and also adds the handler for that notification.

2020-01-27octeontx2-pf: Add packet transmission supportSunil Goutham
This patch adds the packet transmission support. For a given skb prepares send queue descriptors (SQEs) and pushes them to HW. Here driver doesn't maintain it's own SQ rings, SQEs are pushed to HW using a silicon specific operations called LMTST. From the instuction HW derives the transmit queue number and queues the SQE to that queue. These LMTST instructions are designed to avoid queue maintenance in SW and lockless behavior ie when multiple cores are trying to add SQEs to same queue then HW will takecare of serialization, no need for SW to hold locks. Also supports scatter/gather.

2020-01-27octeontx2-pf: Receive packet handling supportSunil Goutham
Added receive packet handling (NAPI) support, error stats, RX_ALL capability config option to passon error pkts to stack upon user request. In subsequent patches these error stats will be added to ethttool. Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-01-27octeontx2-pf: Setup interrupts and NAPI handlerSunil Goutham
Completion queue (CQ) is the one with which HW notifies SW on a packet reception or transmission. Each of the RQ and SQ are mapped to a unique CQ and again both CQs are mapped to same interrupt ie the CINT. So that each core has one interrupt source in whose handler both Rx and Tx notifications are processed. Also - Registered a NAPI handler for the CINT. - Setup coalescing parameters. - IRQ affinity hints etc Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-01-27octeontx2-pf: Initialize and config queuesSunil Goutham
This patch does the initialization of all queues ie the receive buffer pools, receive and transmit queues, completion or notification queues etc. Allocates all required resources (eg transmit schedulers, receive buffers etc) and configures them for proper functioning of queues. Also sets up receive queue's RED dropping levels.

2020-01-27octeontx2-pf: Attach NIX and NPA block LFsSunil Goutham
For a PF to function as a NIC, NPA (for Rx buffers, Tx descriptors etc) and NIX (for rcv, send and completion queues) are the minimum resources needed. So request admin function (AF) to attach one each of NIX and NPA block LFs (local functions). Only AF can configure a LF's contexts, so request AF to allocate memory for NPA aura/pool and NIX RQ/SQ/CQ HW contexts. Upon receiving response, save some of the HW constants like number of pointers per stack page, size of send queue buffer (SQBs, where SQEs are queued by HW) e.t.c which are later used to initialize queues. A HW context here is like a state machine maintained for a descriptor queue. eg size, head/tail pointers, irq etc etc. HW maintains this in memory.

2020-01-27octeontx2-pf: Mailbox communication with AFSunil Goutham
In the resource virtualization unit (RVU) each of the PF and AF (admin function) share a 64KB of reserved memory region for communication. This patch initializes PF <=> AF mailbox IRQs, registers handlers for processing these communication messages. Also adds support to process these messages in both directions ie responses to PF initiated DOWN (PF => AF) messages and AF initiated UP messages (AF => PF). Mbox communication APIs and message formats are defined in AF driver (drivers/net/ethernet/marvell/octeontx2/af), mbox.h from AF driver is included here to avoid duplication.
