2023-08-30Merge tag 'clk-for-linus' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk subsystem updates from Stephen Boyd: "This pull request is full of clk driver changes. In fact, there aren't any changes to the clk framework this time around. That's probably because everyone was on vacation (yours truly included). We did lose a couple clk drivers this time around because nobody was using those devices. That skews the diffstat a bit, but either way, nothing looks out of the ordinary here. The usual suspects are chugging along adding support for more SoCs and fixing bugs. If I had to choose, I'd say the theme for the past few months has been "polish". There's quite a few patches that migrate to devm_platform_ioremap_resource() in here. And there's more than a handful of patches that move the NR_CLKS define from the DT binding header to the driver. There's even patches that migrate drivers to use clk_parent_data and clk_hw to describe clk tree topology. It seems that the spring (summer?) cleaning bug got some folks, or the semiconductor shortage finally hit the software side. New Drivers: - StarFive JH7110 SoC clock drivers - Qualcomm IPQ5018 Global Clock Controller driver - Versa3 clk generator to support 48KHz playback/record with audio codec on RZ/G2L SMARC EVK Removed Drivers: - Remove non-OF mmp clk drivers - Remove OXNAS clk driver Updates: - Add __counted_by to struct clk_hw_onecell_data and struct spmi_pmic_div_clk_cc - Move defines for numbers of clks (NR_CLKS) from DT headers to drivers - Introduce kstrdup_and_replace() and use it - Add PLL rates for Rockchip rk3568 - Add the display clock tree for Rockchip rv1126 - Add Audio Clock Generator (ADG) clocks on Renesas R-Car Gen3 and RZ/G2 SoCs - Convert sun9i-mmc clock to use devm_platform_get_and_ioremap_resource() - Fix function name in a comment in ccu_mmc_timing.c - Parameter name correction for ccu_nkm_round_rate() - Implement CLK_SET_RATE_PARENT for Allwinner NKM clocks, i.e. consider alternative parent rates when determining clock rates - Set CLK_SET_RATE_PARENT for Allwinner A64 pll-mipi - Support finding closest (as opposed to closest but not higher) clock rate for NM, NKM, mux and div type clocks, as use it for Allwinner A64 pll-video0 - Prefer current parent rate if able to generate ideal clock rate for Allwinner NKM clocks - Clean up Qualcomm SMD RPM driver, with interconnect bus clocks moved out to the interconnect drivers - Fix various PM runtime bugs across many Qualcomm clk drivers - Migrate Qualcomm MDM9615 is to parent_hw and parent_data - Add network related resets on Qualcomm IPQ4019 - Add a couple missing USB related clocks to Qualcomm IPQ9574 - Add missing gpll0_sleep_clk_src to Qualcomm MSM8917 global clock controller - In the Qualcomm QDU1000 global clock controller, GDSCs, clkrefs, and GPLL1 are added, while PCIe pipe clock, SDCC rcg ops are corrected - Add missing GDSCs to and correct GDSCs for the SC8280XP global clock controller driver - Support retention for the Qualcomm SC8280XP display clock controller GDSCs. - Qualcommm's SDCC apps_clk_src is marked with CLK_OPS_PARENT_ENABLE to fix issues with missing parent clocks across sc7180, sm7150, sm6350 and sm8250, while sm8450 is corrected to use floor ops - Correct Qualcomm SM6350 GPU clock controller's clock supplies - Drop unwanted clocks from the Qualcomm IPQ5332 GCC driver - Add missing OXILICX GDSC to Qualcomm MSM8226 GCC - Change the delay in the Qualcomm reset controller to fsleep() for correctness - Extend the Qualcomm SM83550 Video clock controller to support SC8280XP - Add graphics clock support on Renesas RZ/G2M, RZ/G2N, RZ/G2E, and R-Car H3, M3-W, and M3-N SoCs - Add Clocked Serial Interface (CSI) clocks on Renesas RZ/V2M - Add PWM (MTU3) clock and reset on Renesas RZ/G2UL and RZ/Five - Add the PDM IPC clock for i.MX93 - Add 519.75MHz frequency support for i.MX9 PLL - Simplify the .determine_rate() implementation for i.MX GPR mux - Make the i.MX8QXP LPCG clock use devm_platform_ioremap_resource() - Add the audio mux clock to i.MX8 - Fix the SPLL2 MULT range for PLLv4 - Update the SPLL2 type in i.MX8ULP - Fix the SAI4 clock on i.MX8MP - Add silicon revision print for i.MX25 on clocks init - Drop the return value from __mx25_clocks_init() - Fix the clock pauses on no-op set_rate for i.MX8M composite clock - Drop restrictions for i.MX PLL14xx and fix its max prediv value - Drop the 393216000 and 361267200 from i.MX PLL14xx rate table to allow glitch free switching" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (207 commits) clk: qcom: Fix SM_GPUCC_8450 dependencies clk: lmk04832: Support using PLL1_LD as SPI readback pin clk: lmk04832: Don't disable vco clock on probe fail clk: lmk04832: Set missing parent_names for output clocks clk: mvebu: Convert to devm_platform_ioremap_resource() clk: nuvoton: Convert to devm_platform_ioremap_resource() clk: socfpga: agilex: Convert to devm_platform_ioremap_resource() clk: ti: Use devm_platform_get_and_ioremap_resource() clk: mediatek: Convert to devm_platform_ioremap_resource() clk: hsdk-pll: Convert to devm_platform_ioremap_resource() clk: gemini: Convert to devm_platform_ioremap_resource() clk: fsl-sai: Convert to devm_platform_ioremap_resource() clk: bm1880: Convert to devm_platform_ioremap_resource() clk: axm5516: Convert to devm_platform_ioremap_resource() clk: actions: Convert to devm_platform_ioremap_resource() clk: cdce925: Remove redundant of_match_ptr() clk: pxa910: Move number of clocks to driver source clk: pxa1928: Move number of clocks to driver source clk: pxa168: Move number of clocks to driver source clk: mmp2: Move number of clocks to driver source ...

Pull xfs updates from Chandan Babu: - Chandan Babu will be taking over as the XFS release manager. He has reviewed all the patches that are in this branch, though I'm signing the branch one last time since I'm still technically maintainer. :P - Create a maintainer entry profile for XFS in which we lay out the various roles that I have played for many years. Aside from release manager, the remaining roles are as yet unfilled. - Start merging online repair -- we now have in-memory pageable memory for staging btrees, a bunch of pending fixes, and we've started the process of refactoring the scrub support code to support more of repair. In particular, reaping of old blocks from damaged structures. - Scrub the realtime summary file. - Fix a bug where scrub's quota iteration only ever returned the root dquot. Oooops. - Fix some typos.

These were added initially as copies from liburing, but all of them have since bitrotted and are way out of date at this point. Rather than attempt to keep them in sync, just get rid of them.

Pull rust updates from Miguel Ojeda: "In terms of lines, most changes this time are on the pinned-init API and infrastructure. While we have a Rust version upgrade, and thus a bunch of changes from the vendored 'alloc' crate as usual, this time those do not account for many lines. Toolchain and infrastructure: - Upgrade to Rust 1.71.1. This is the second such upgrade, which is a smaller jump compared to the last time. This version allows us to remove the '__rust_*' allocator functions -- the compiler now generates them as expected, thus now our 'KernelAllocator' is used. It also introduces the 'offset_of!' macro in the standard library (as an unstable feature) which we will need soon. So far, we were using a declarative macro as a prerequisite in some not-yet-landed patch series, which did not support sub-fields (i.e. nested structs): #[repr(C)] struct S { a: u16, b: (u8, u8), } assert_eq!(offset_of!(S, b.1), 3); - Upgrade to bindgen 0.65.1. This is the first time we upgrade its version. Given it is a fairly big jump, it comes with a fair number of improvements/changes that affect us, such as a fix needed to support LLVM 16 as well as proper support for '__noreturn' C functions, which are now mapped to return the '!' type in Rust: void __noreturn f(void); // C pub fn f() -> !; // Rust - 'scripts/rust_is_available.sh' improvements and fixes. This series takes care of all the issues known so far and adds a few new checks to cover for even more cases, plus adds some more help texts. All this together will hopefully make problematic setups easier to identify and to be solved by users building the kernel. In addition, it adds a test suite which covers all branches of the shell script, as well as tests for the issues found so far. - Support rust-analyzer for out-of-tree modules too. - Give 'cfg's to rust-analyzer for the 'core' and 'alloc' crates. - Drop 'scripts/is_rust_module.sh' since it is not needed anymore. Macros crate: - New 'paste!' proc macro. This macro is a more flexible version of 'concat_idents!': it allows the resulting identifier to be used to declare new items and it allows to transform the identifiers before concatenating them, e.g. let x_1 = 42; paste!(let [<x _2>] = [<x _1>];); assert!(x_1 == x_2); The macro is then used for several of the pinned-init API changes in this pull. Pinned-init API: - Make '#[pin_data]' compatible with conditional compilation of fields, allowing to write code like: #[pin_data] pub struct Foo { #[cfg(CONFIG_BAR)] a: Bar, #[cfg(not(CONFIG_BAR))] a: Baz, } - New '#[derive(Zeroable)]' proc macro for the 'Zeroable' trait, which allows 'unsafe' implementations for structs where every field implements the 'Zeroable' trait, e.g.: #[derive(Zeroable)] pub struct DriverData { id: i64, buf_ptr: *mut u8, len: usize, } - Add '..Zeroable::zeroed()' syntax to the 'pin_init!' macro for zeroing all other fields, e.g.: pin_init!(Buf { buf: [1; 64], ..Zeroable::zeroed() }); - New '{,pin_}init_array_from_fn()' functions to create array initializers given a generator function, e.g.: let b: Box<[usize; 1_000]> = Box::init::<Error>( init_array_from_fn(|i| i) ).unwrap(); assert_eq!(b.len(), 1_000); assert_eq!(b[123], 123); - New '{,pin_}chain' methods for '{,Pin}Init<T, E>' that allow to execute a closure on the value directly after initialization, e.g.: let foo = init!(Foo { buf <- init::zeroed() }).chain(|foo| { foo.setup(); Ok(()) }); - Support arbitrary paths in init macros, instead of just identifiers and generic types. - Implement the 'Zeroable' trait for the 'UnsafeCell<T>' and 'Opaque<T>' types. - Make initializer values inaccessible after initialization. - Make guards in the init macros hygienic. 'allocator' module: - Use 'krealloc_aligned()' in 'KernelAllocator::alloc' preventing misaligned allocations when the Rust 1.71.1 upgrade is applied later in this pull. The equivalent fix for the previous compiler version (where 'KernelAllocator' is not yet used) was merged into 6.5 already, which added the 'krealloc_aligned()' function used here. - Implement 'KernelAllocator::{realloc, alloc_zeroed}' for performance, using 'krealloc_aligned()' too, which forwards the call to the C API. 'types' module: - Make 'Opaque' be '!Unpin', removing the need to add a 'PhantomPinned' field to Rust structs that contain C structs which must not be moved. - Make 'Opaque' use 'UnsafeCell' as the outer type, rather than inner. Documentation: - Suggest obtaining the source code of the Rust's 'core' library using the tarball instead of the repository. MAINTAINERS: - Andreas and Alice, from Samsung and Google respectively, are joining as reviewers of the "RUST" entry.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull scheduler updates from Ingo Molnar: - The biggest change is introduction of a new iteration of the SCHED_FAIR interactivity code: the EEVDF ("Earliest Eligible Virtual Deadline First") scheduler EEVDF too is a virtual-time scheduler, with two parameters (weight and relative deadline), compared to CFS that had weight only. It completely reworks the base scheduler: placement, preemption, picking -- everything LWN.net, as usual, has a terrific writeup about EEVDF: https://lwn.net/Articles/925371/ Preemption (both tick and wakeup) is driven by testing against a fresh pick. Because the tree is now effectively an interval tree, and the selection is no longer the 'leftmost' task, over-scheduling is less of a problem. A lot of the CFS heuristics are removed or replaced by more natural latency-space parameters & constructs In terms of expected performance regressions: we will and can fix everything where a 'good' workload misbehaves with the new scheduler, but EEVDF inevitably changes workload scheduling in a binary fashion, hopefully for the better in the overwhelming majority of cases, but in some cases it won't, especially in adversarial loads that got lucky with the previous code, such as some variants of hackbench.

2023-08-25net: pcs: xpcs: support to switch mode for Wangxun NICsJiawen Wu
According to chapter 6 of DesignWare Cores Ethernet PCS (version 3.20a) and custom design manual, add a configuration flow for switching interface mode. If the interface changes, the following setting is required: 1. wait VR_XS_PCS_DIG_STS bit(4, 2) [PSEQ_STATE] = 100b (Power-Good) 2. write SR_XS_PCS_CTRL2 to select various PCS type 3. write SR_PMA_CTRL1 and/or SR_XS_PCS_CTRL1 for link speed 4. program PMA registers 5. write VR_XS_PCS_DIG_CTRL1 bit(15) [VR_RST] = 1b (Vendor-Specific Soft Reset) 6. wait for VR_XS_PCS_DIG_CTRL1 bit(15) [VR_RST] to get cleared Only 10GBASE-R/SGMII/1000BASE-X modes are planned for the current Wangxun devices. And there is a quirk for Wangxun devices to switch mode although the interface in phylink state has not changed, since PCS will change to default 10GBASE-R when the ethernet driver(txgbe) do LAN reset.

2023-08-18mm: allow per-VMA locks on file-backed VMAsMatthew Wilcox (Oracle)
Remove the TCP layering violation by allowing per-VMA locks on all VMAs. The fault path will immediately fail in handle_mm_fault(). There may be a small performance reduction from this patch as a little unnecessary work will be done on each page fault. See later patches for the improvement.
