2020-01-27thermal: stm32: Fix low threshold interrupt floodPascal Paillet1-1/+2
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 Mamonov1-1/+1
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 <[email protected]> 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.

2020-01-27qed: rt init valid initialization changedMichal Kalderon3-21/+6
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. Signed-off-by: Ariel Elior <[email protected]> Signed-off-by: Michal Kalderon <[email protected]> Signed-off-by: David S.

2020-01-27qed: FW 8.42.2.0 Additional ll2 typeMichal Kalderon11-37/+235
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.

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.

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.

This reverts commit 7786a1af2a6bceb07860ec720e74714004438834. It causes build failures on 32-bit, for example: net/core/pktgen.o: In function `mod_cur_headers': >> pktgen.c:(.text.mod_cur_headers+0xba0): undefined reference to `__umoddi3' Signed-off-by: David S. Miller <[email protected]>
2020-01-27net/core: Replace driver version to be kernel versionLeon Romanovsky1-0/+2
In order to stop useless driver version bumps and unify output presented by ethtool -i, let's set default version string. As Linus said in [1]: "Things are supposed to be backwards and forwards compatible, because we don't accept breakage in user space anyway. So versioning is pointless, and only causes problems." They cause problems when users start to see version changes and expect specific set of features which will be different for stable@, vanilla and distribution kernels. Distribution kernels are based on some kernel version with extra patches on top, for example, in RedHat world this "extra" is a lot and for them your driver version say nothing. Users who run vanilla kernels won't use driver version information too, because running such kernels requires knowledge and understanding. Another set of problems are related to difference in versioning scheme and such doesn't allow to write meaningful automation which will work sanely on all ethtool capable devices. Before this change: [leonro@erver ~]$ ethtool -i eth0 driver: virtio_net version: 1.0.0 After this change and once ->version assignment will be deleted from virtio_net: [leonro@server ~]$ ethtool -i eth0 driver: virtio_net version: 5.5.0-rc6+ Link: https://lore.kernel.org/ksummit-discuss/CA+55aFx9A=5cc0QZ7CySC4F2K7eYaEfzkdYEc9JaNgCcV25=rg@mail.gmail.com/ Link: https://lore.kernel.org/linux-rdma/[email protected]/T/#md460ff8f976c532a89d6860411c3c50bb811038b Link: https://lore.kernel.org/linux-rdma/[email protected] Signed-off-by: Leon Romanovsky <[email protected]> Acked-by: Shannon Nelson <[email protected]> Signed-off-by: David S.

2020-01-27Merge branch 'sfc-refactor-mcdi-filtering-code'David S. Miller4-2373/+2476
Alex Maftei says: ==================== sfc: refactor mcdi filtering code Splitting final bits of the driver code into different files, which will later be used in another driver for a new product. This is a continuation to my previous patch series. (three of them) Refactoring will be concluded with this series, for now. As instructed, split the renaming and moving into different patches. Removed stray spaces before tabs... twice. Minor refactoring was done with the renaming, as explained in the first patch. ==================== Signed-off-by: David S. Miller <[email protected]>

2020-01-27thermal: rcar_gen3_thermal: Remove temperature boundNiklas Söderlund1-3/+1
The hardware manual states that the operation of the sensor is not guaranteed with temperatures above 125°C, not that the readings are invalid. Remove the bound check and try to deliver temperature readings even if we are outside the guaranteed operation range.
