2022-09-27dt-bindings: riscv: microchip: document icicle reference designConor Dooley1-6/+12
The icicle kit reference design's v2022.09 release made some changes to the memory map - including adding the ability to read the fabric clock controllers via the system controller bus & making the PCI controller work with upstream Linux. While the PCI was not working in the v2022.03 design, so nothing is broken there in terms of backwards compatibility, the fabric clocks used in the v2022.03 design were chosen by the individual run of the synthesis tool. In the v2022.09 reference design, the clocks are fixed to use the "north west" fabric Clock Conditioning Circuitry. In the v2022.10 release, the memory map on the DDR side is also changing, so to avoid making a breaking change here twice, jump over the v2022.09 release and straight to the v2022.10 one. Make use of a new compatible to denote that v2022.{09,10} reference design releases are not backwards compatible.

SoC MT7621 SPI bindings used text format, so migrate them to YAML. There are some additions to the binding that were not in the original file. This binding is used in MT7621 and MT7628a Ralink SoCs. To properly match both dts nodes in tree we need to add to the schema 'clocks', 'clock-names' and 'reset-names'. Both 'clock-names' and 'reset-names' use 'spi' as string so maintain that as const in the schema.

2022-09-26Maple Tree: add new data structureLiam R. Howlett2-0/+218
Patch series "Introducing the Maple Tree" The maple tree is an RCU-safe range based B-tree designed to use modern processor cache efficiently. There are a number of places in the kernel that a non-overlapping range-based tree would be beneficial, especially one with a simple interface. If you use an rbtree with other data structures to improve performance or an interval tree to track non-overlapping ranges, then this is for you. The tree has a branching factor of 10 for non-leaf nodes and 16 for leaf nodes. With the increased branching factor, it is significantly shorter than the rbtree so it has fewer cache misses. The removal of the linked list between subsequent entries also reduces the cache misses and the need to pull in the previous and next VMA during many tree alterations. The first user that is covered in this patch set is the vm_area_struct, where three data structures are replaced by the maple tree: the augmented rbtree, the vma cache, and the linked list of VMAs in the mm_struct. The long term goal is to reduce or remove the mmap_lock contention. The plan is to get to the point where we use the maple tree in RCU mode. Readers will not block for writers. A single write operation will be allowed at a time. A reader re-walks if stale data is encountered. VMAs would be RCU enabled and this mode would be entered once multiple tasks are using the mm_struct. Davidlor said : Yes I like the maple tree, and at this stage I don't think we can ask for : more from this series wrt the MM - albeit there seems to still be some : folks reporting breakage. Fundamentally I see Liam's work to (re)move : complexity out of the MM (not to say that the actual maple tree is not : complex) by consolidating the three complimentary data structures very : much worth it considering performance does not take a hit. This was very : much a turn off with the range locking approach, which worst case scenario : incurred in prohibitive overhead. Also as Liam and Matthew have : mentioned, RCU opens up a lot of nice performance opportunities, and in : addition academia[1] has shown outstanding scalability of address spaces : with the foundation of replacing the locked rbtree with RCU aware trees. A similar work has been discovered in the academic press https://pdos.csail.mit.edu/papers/rcuvm:asplos12.pdf Sheer coincidence. We designed our tree with the intention of solving the hardest problem first. Upon settling on a b-tree variant and a rough outline, we researched ranged based b-trees and RCU b-trees and did find that article. So it was nice to find reassurances that we were on the right path, but our design choice of using ranges made that paper unusable for us. This patch (of 70): The maple tree is an RCU-safe range based B-tree designed to use modern processor cache efficiently. There are a number of places in the kernel that a non-overlapping range-based tree would be beneficial, especially one with a simple interface. If you use an rbtree with other data structures to improve performance or an interval tree to track non-overlapping ranges, then this is for you. The tree has a branching factor of 10 for non-leaf nodes and 16 for leaf nodes. With the increased branching factor, it is significantly shorter than the rbtree so it has fewer cache misses. The removal of the linked list between subsequent entries also reduces the cache misses and the need to pull in the previous and next VMA during many tree alterations. The first user that is covered in this patch set is the vm_area_struct, where three data structures are replaced by the maple tree: the augmented rbtree, the vma cache, and the linked list of VMAs in the mm_struct.

A single write operation will be allowed at a time. A reader re-walks if stale data is encountered. VMAs would be RCU enabled and this mode would be entered once multiple tasks are using the mm_struct. There is additional BUG_ON() calls added within the tree, most of which are in debug code. These will be replaced with a WARN_ON() call in the future. There is also additional BUG_ON() calls within the code which will also be reduced in number at a later date. These exist to catch things such as out-of-range accesses which would crash anyways.

2022-09-26filemap: make the accounting of thrashing more consistentYang Yang1-1/+1
Once upon a time, we only support accounting thrashing of page cache. Then Joonsoo introduced workingset detection for anonymous pages and we gained the ability to account thrashing of them[1]. So let delayacct account both the thrashing of page cache and anonymous pages, this could make the codes more consistent and simpler.

SoC MT7621 I2C bindings used text format, so migrate them to YAML. There are some additions to the binding that were not in the original txt file. This binding is used in MT7621 and MT7628a Ralink SoCs. To properly match both dts nodes in tree we need to add to the schema 'clocks', 'clock-names' and 'reset-names'. Both 'clock-names' and 'reset-names' use 'i2c' as string so maintain that as const in the schema. Also, Properly update MAINTAINERS file to align the changes.

2022-09-26dt-bindings: timer: arm,arch_timer: Allow dual compatible stringJean-Philippe Brucker1-6/+5
Since the Armv7 and Armv8 architected timers are compatible, it is valid to expose a devicetree node with compatible string "arm,armv8-timer" followed by "arm,armv7-timer". For example a 32-bit guest running on a 64-bit machine may look for the v7 string even though the hardware is v8. VMMs such as QEMU and kvmtool have been using this compatible string for some time. Clean up the compatible list a little and add the dual option.

2022-09-26dt-bindings: iommu: arm,smmu-v3: Relax order of interrupt namesJean-Philippe Brucker1-10/+5
The QEMU devicetree uses a different order for SMMUv3 interrupt names, and there isn't a good reason for enforcing a specific order. Since all interrupt lines are optional, operating systems should not expect a fixed interrupt array layout; they should instead match each interrupt to its name individually. Besides, as a result of commit e4783856a2e8 ("dt-bindings: iommu: arm,smmu-v3: make PRI IRQ optional"), "cmdq-sync" and "priq" are already permutable. Relax the interrupt-names array entirely by allowing any permutation, incidentally making the schema more readable. Note that dt-validate won't allow duplicate names here so we don't need to specify maxItems or add additional checks, it's quite neat.
