From my perspective I think it's an experiment worth going with and seeing how the benefits/noise playout keeping these files useful. Ideally I'd like to get this so we can do pre-merge testing on PRs eventually. Below is some info from danvet on why we've ended up making the decision and how we can roll it back if we decide it was a bad plan. Why in upstream? - like documentation, testcases, tools CI integration is one of these things where you can waste endless amounts of time if you accidentally have a version that doesn't match your source code - but also like the above, there's a balance, this is the initial cut of what we think makes sense to keep in sync vs out-of-tree, probably needs adjustment - gitlab supports out-of-repo gitlab integration and that's what's been used for the kernel in drm, but it results in per-driver fragmentation and lots of duplicated effort. the simple act of smashing an arbitrary winner into a topic branch already started surfacing patches on dri-devel and sparking good cross driver team discussions Why gitlab? - it's not any more shit than any of the other CI - drm userspace uses it extensively for everything in userspace, we have a lot of people and experience with this, including integration of hw testing labs - media userspace like gstreamer is also on gitlab.fd.o, and there's discussion to extend this to the media subsystem in some fashion Can this be shared? - there's definitely a pile of code that could move to scripts/ if other subsystem adopt ci integration in upstream kernel git. other bits are more drm/gpu specific like the igt-gpu-tests/tools integration - docker images can be run locally or in other CI runners Will we regret this? - it's all in one directory, intentionally, for easy deletion - probably 1-2 years in upstream to see whether this is worth it or a Big Mistake. that's roughly what it took to _really_ roll out solid CI in the bigger userspace projects we have on gitlab.fd.o like mesa3d" * tag 'topic/drm-ci-2023-08-31-1' of git://anongit.freedesktop.org/drm/drm: drm: ci: docs: fix build warning - add missing escape drm: Add initial ci/ subdirectory 10 September 2023, 18:55:26 UTC

That is where development now takes place and myself and Namhyung Kim have write access, more people to come as we emulate other maintainer groups. perf record: - Record kernel data maps when 'perf record --data' is used, so that global variables can be resolved and used in tools that do data profiling. perf trace: - Remove the old, experimental support for BPF events in which a .c file was passed as an event: "perf trace -e hello.c" to then get compiled and loaded. The only known usage for that, that shipped with the kernel as an example for such events, augmented the raw_syscalls tracepoints and was converted to a libbpf skeleton, reusing all the user space components and the BPF code connected to the syscalls. In the end just the way to glue the BPF part and the user space type beautifiers changed, now being performed by libbpf skeletons. The next step is to use BTF to do pretty printing of all syscall types, as discussed with Alan Maguire and others. Now, on a perf built with BUILD_BPF_SKEL=1 we get most if not all path/filenames/strings, some of the networking data structures, perf_event_attr, etc, i.e. systemwide tracing of nanosleep calls and perf_event_open syscalls while 'perf stat' runs 'sleep' for 5 seconds: # perf trace -a -e *nanosleep,perf* perf stat -e cycles,instructions sleep 5 0.000 ( 9.034 ms): perf/327641 perf_event_open(attr_uptr: { type: 0 (PERF_TYPE_HARDWARE), size: 136, config: 0 (PERF_COUNT_HW_CPU_CYCLES), sample_type: IDENTIFIER, read_format: TOTAL_TIME_ENABLED|TOTAL_TIME_RUNNING, disabled: 1, inherit: 1, enable_on_exec: 1, exclude_guest: 1 }, pid: 327642 (perf), cpu: -1, group_fd: -1, flags: FD_CLOEXEC) = 3 9.039 ( 0.006 ms): perf/327641 perf_event_open(attr_uptr: { type: 0 (PERF_TYPE_HARDWARE), size: 136, config: 0x1 (PERF_COUNT_HW_INSTRUCTIONS), sample_type: IDENTIFIER, read_format: TOTAL_TIME_ENABLED|TOTAL_TIME_RUNNING, disabled: 1, inherit: 1, enable_on_exec: 1, exclude_guest: 1 }, pid: 327642 (perf-exec), cpu: -1, group_fd: -1, flags: FD_CLOEXEC) = 4 ?

Since we now default to NDEBUG=1, we ended up segfaulting when building with BUILD_NONDISTRO=1 because a needed initialization routine was being "error checked" via an assert. Fix it by explicitly checking the result and aborting instead if it fails. We better back propagate the error, but at least 'perf annotate' on samples collected for a BPF program is back working when perf is built with BUILD_NONDISTRO=1. perf report/top: - Add back TUI hierarchy mode header, that is seen when using 'perf report/top --hierarchy'. - Fix the number of entries for 'e' key in the TUI that was preventing navigation of lines when expanding an entry. perf report/script: - Support cross platform register handling, allowing a perf.data file collected on one architecture to have registers sampled correctly displayed when analysis tools such as 'perf report' and 'perf script' are used on a different architecture. - Fix handling of event attributes in pipe mode, i.e. when one uses: perf record -o - | perf report -i - When no perf.data files are used. - Handle files generated via pipe mode with a version of perf and then read also via pipe mode with a different version of perf, where the event attr record may have changed, use the record size field to properly support this version mismatch. perf probe: - Accessing global variables from uprobes isn't supported, make the error message state that instead of stating that some minimal kernel version is needed to have that feature. This seems just a tool limitation, the kernel probably has all that is needed. perf tests: - Fix a reference count related leak in the dlfilter v0 API where the result of a thread__find_symbol_fb() is not matched with an addr_location__exit() to drop the reference counts of the resolved components (machine, thread, map, symbol, etc). Add a dlfilter test to make sure that doesn't regresses. - Lots of fixes for the 'perf test' written in shell script related to problems found with the shellcheck utility. - Fixes for 'perf test' shell scripts testing features enabled when perf is built with BUILD_BPF_SKEL=1, such as 'perf stat' bpf counters. - Add perf record sample filtering test, things like the following example, that gets implemented as a BPF filter attached to the event: # perf record -e task-clock -c 10000 --filter 'ip < 0xffffffff00000000' - Improve the way the task_analyzer test checks if libtraceevent is linked, using 'perf version --build-options' instead of the more expensinve 'perf record -e "sched:sched_switch"'. - Add support for riscv in the mmap-basic test. (This went as well via the RiscV tree, same contents). libperf: - Implement riscv mmap support (This went as well via the RiscV tree, same contents). perf script: - New tool that converts perf.data files to the firefox profiler format so that one can use the visualizer at https://profiler.firefox.com/. Done by Anup Sharma as part of this year's Google Summer of Code. One can generate the output and upload it to the web interface but Anup also automated everything: perf script gecko -F 99 -a sleep 60 - Support syscall name parsing on arm64. - Print "cgroup" field on the same line as "comm". perf bench: - Add new 'uprobe' benchmark to measure the overhead of uprobes with/without BPF programs attached to it. - breakpoints are not available on power9, skip that test. perf stat: - Add #num_cpus_online literal to be used in 'perf stat' metrics, and add this extra 'perf test' check that exemplifies its purpose: TEST_ASSERT_VAL("#num_cpus_online", expr__parse(&num_cpus_online, ctx, "#num_cpus_online") == 0); TEST_ASSERT_VAL("#num_cpus", expr__parse(&num_cpus, ctx, "#num_cpus") == 0); TEST_ASSERT_VAL("#num_cpus >= #num_cpus_online", num_cpus >= num_cpus_online); Miscellaneous: - Improve tool startup time by lazily reading PMU, JSON, sysfs data. - Improve error reporting in the parsing of events, passing YYLTYPE to error routines, so that the output can show were the parsing error was found. - Add 'perf test' entries to check the parsing of events improvements. - Fix various leak for things detected by -fsanitize=address, mostly things that would be freed at tool exit, including: - Free evsel->filter on the destructor. - Allow tools to register a thread->priv destructor and use it in 'perf trace'. - Free evsel->priv in 'perf trace'. - Free string returned by synthesize_perf_probe_point() when the caller fails to do all it needs. - Adjust various compiler options to not consider errors some warnings when building with broken headers found in things like python, flex, bison, as we otherwise build with -Werror. Some for gcc, some for clang, some for some specific version of those, some for some specific version of flex or bison, or some specific combination of these components, bah. - Allow customization of clang options for BPF target, this helps building on gentoo where there are other oddities where BPF targets gets passed some compiler options intended for the native build, so building with WERROR=0 helps while these oddities are fixed. - Dont pass ERR_PTR() values to perf_session__delete() in 'perf top' and 'perf lock', fixing some segfaults when handling some odd failures. - Add LTO build option. - Fix format of unordered lists in the perf docs (tools/perf/Documentation) - Overhaul the bison files, using constructs such as YYNOMEM. - Remove unused tokens from the bison .y files. - Add more comments to various structs. - A few LoongArch enablement patches. Vendor events (JSON): - Add JSON metrics for Yitian 710 DDR (aarch64). Things like: EventName, BriefDescription visible_window_limit_reached_rd, "At least one entry in read queue reaches the visible window limit.", visible_window_limit_reached_wr, "At least one entry in write queue reaches the visible window limit.", op_is_dqsosc_mpc , "A DQS Oscillator MPC command to DRAM.", op_is_dqsosc_mrr , "A DQS Oscillator MRR command to DRAM.", op_is_tcr_mrr , "A Temperature Compensated Refresh(TCR) MRR command to DRAM.", - Add AmpereOne metrics (aarch64). - Update N2 and V2 metrics (aarch64) and events using Arm telemetry repo. - Update scale units and descriptions of common topdown metrics on aarch64.

It resolves a problem with the way that symbol_get was changed in the module tree merge in your tree to fix up the DVB drivers which rely on this old api to attach new devices. As the changelog comment says: In commit 9011e49d54dc ("modules: only allow symbol_get of EXPORT_SYMBOL_GPL modules") the use of symbol_get is properly restricted to GPL-only marked symbols. This interacts oddly with the DVB logic which only uses dvb_attach() to load the dvb driver which then uses symbol_get(). Fix this up by properly marking all of the dvb_attach attach symbols as EXPORT_SYMBOL_GPL(). This has been acked by Hans from the V4L driver side, Luis from the module side, Mauro on the media side, and Christoph said it was the correct solution, and was tested by the original reporter of the issue.

But NVIDIA thinks the issue is probably related to some issue with the Root Port, not with the T4. The T4 provides neither PM nor FLR reset, so masking bus reset compromises this device for assignment scenarios. Revert d5af729dc207 as requested by Wu Zongyong. This will leave SBR broken in the specific configuration Wu tested, as it was in v6.5, so Wu will debug that further.

Song Liu introduced the BPF prog pack allocator[1] to mitigate the above issue. It packs multiple BPF programs into a single huge page. It is currently only enabled for the x86_64 BPF JIT. I enabled this allocator on the ARM64 BPF JIT[2]. It is being reviewed now. This patch series enables the BPF prog pack allocator for the RISCV BPF JIT. ====================================================== Performance Analysis of prog pack allocator on RISCV64 ====================================================== Test setup: =========== Host machine: Debian GNU/Linux 11 (bullseye) Qemu Version: QEMU emulator version 8.0.3 (Debian 1:8.0.3+dfsg-1) u-boot-qemu Version: 2023.07+dfsg-1 opensbi Version: 1.3-1 To test the performance of the BPF prog pack allocator on RV, a stresser tool[4] linked below was built. This tool loads 8 BPF programs on the system and triggers 5 of them in an infinite loop by doing system calls. The runner script starts 20 instances of the above which loads 8*20=160 BPF programs on the system, 5*20=100 of which are being constantly triggered. The script is passed a command which would be run in the above environment. The script was run with following perf command: ./run.sh "perf stat -a \ -e iTLB-load-misses \ -e dTLB-load-misses \ -e dTLB-store-misses \ -e instructions \ --timeout 60000" The output of the above command is discussed below before and after enabling the BPF prog pack allocator. The tests were run on qemu-system-riscv64 with 8 cpus, 16G memory. The rootfs was created using Bjorn's riscv-cross-builder[5] docker container linked below. Results ======= Before enabling prog pack allocator: ------------------------------------ Performance counter stats for 'system wide': 4939048 iTLB-load-misses 5468689 dTLB-load-misses 465234 dTLB-store-misses 1441082097998 instructions 60.045791200 seconds time elapsed After enabling prog pack allocator: ----------------------------------- Performance counter stats for 'system wide': 3430035 iTLB-load-misses 5008745 dTLB-load-misses 409944 dTLB-store-misses 1441535637988 instructions 60.046296600 seconds time elapsed Improvements in metrics ======================= It was expected that the iTLB-load-misses would decrease as now a single huge page is used to keep all the BPF programs compared to a single page for each program earlier. -------------------------------------------- The improvement in iTLB-load-misses: -30.5 % -------------------------------------------- I repeated this expriment more than 100 times in different setups and the improvement was always greater than 30%. This patch series is boot tested on the Starfive VisionFive 2 board[6]. The performance analysis was not done on the board because it doesn't expose iTLB-load-misses, etc. The stresser program was run on the board to test the loading and unloading of BPF programs [1] https://lore.kernel.org/bpf/20220204185742.271030-1-song@kernel.org/ [2] https://lore.kernel.org/all/20230626085811.3192402-1-puranjay12@gmail.com/ [3] https://lore.kernel.org/all/20230626085811.3192402-2-puranjay12@gmail.com/ [4] https://github.com/puranjaymohan/BPF-Allocator-Bench [5] https://github.com/bjoto/riscv-cross-builder [6] https://www.starfivetech.com/en/site/boards * b4-shazam-merge: bpf, riscv: use prog pack allocator in the BPF JIT riscv: implement a memset like function for text riscv: extend patch_text_nosync() for multiple pages bpf: make bpf_prog_pack allocator portable Link: https://lore.kernel.org/r/20230831131229.497941-1-puranjay12@gmail.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com> 08 September 2023, 18:25:25 UTC

c23be91 Palmer Dabbelt 08 September 2023, 18:24:34 UTC Merge patch series "Add non-coherent DMA support for AX45MP" Prabhakar <prabhakar.csengg@gmail.com> says: From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com> non-coherent DMA support for AX45MP ==================================== On the Andes AX45MP core, cache coherency is a specification option so it may not be supported. In this case DMA will fail. To get around with this issue this patch series does the below: 1] Andes alternative ports is implemented as errata which checks if the IOCP is missing and only then applies to CMO errata. One vendor specific SBI EXT (ANDES_SBI_EXT_IOCP_SW_WORKAROUND) is implemented as part of errata. Below are the configs which Andes port provides (and are selected by RZ/Five): - ERRATA_ANDES - ERRATA_ANDES_CMO OpenSBI patch supporting ANDES_SBI_EXT_IOCP_SW_WORKAROUND SBI is now part v1.3 release. 2] Andes AX45MP core has a Programmable Physical Memory Attributes (PMA) block that allows dynamic adjustment of memory attributes in the runtime. It contains a configurable amount of PMA entries implemented as CSR registers to control the attributes of memory locations in interest. OpenSBI configures the PMA regions as required and creates a reserve memory node and propagates it to the higher boot stack. Currently OpenSBI (upstream) configures the required PMA region and passes this a shared DMA pool to Linux. reserved-memory { #address-cells = <2>; #size-cells = <2>; ranges; pma_resv0@58000000 { compatible = "shared-dma-pool"; reg = <0x0 0x58000000 0x0 0x08000000>; no-map; linux,dma-default; }; }; The above shared DMA pool gets appended to Linux DTB so the DMA memory requests go through this region. 3] We provide callbacks to synchronize specific content between memory and cache. 4] RZ/Five SoC selects the below configs - AX45MP_L2_CACHE - DMA_GLOBAL_POOL - ERRATA_ANDES - ERRATA_ANDES_CMO ----------x---------------------x--------------------x---------------x---- * b4-shazam-merge: soc: renesas: Kconfig: Select the required configs for RZ/Five SoC cache: Add L2 cache management for Andes AX45MP RISC-V core dt-bindings: cache: andestech,ax45mp-cache: Add DT binding documentation for L2 cache controller riscv: mm: dma-noncoherent: nonstandard cache operations support riscv: errata: Add Andes alternative ports riscv: asm: vendorid_list: Add Andes Technology to the vendors list Link: https://lore.kernel.org/r/20230818135723.80612-1-prabhakar.mahadev-lad.rj@bp.renesas.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com> 08 September 2023, 18:24:34 UTC

580253b Palmer Dabbelt 08 September 2023, 18:24:12 UTC Merge patch series "RISC-V: Probe for misaligned access speed" Evan Green <evan@rivosinc.com> says: The current setting for the hwprobe bit indicating misaligned access speed is controlled by a vendor-specific feature probe function. This is essentially a per-SoC table we have to maintain on behalf of each vendor going forward. Let's convert that instead to something we detect at runtime. We have two assembly routines at the heart of our probe: one that does a bunch of word-sized accesses (without aligning its input buffer), and the other that does byte accesses. If we can move a larger number of bytes using misaligned word accesses than we can with the same amount of time doing byte accesses, then we can declare misaligned accesses as "fast". The tradeoff of reducing this maintenance burden is boot time. We spend 4-6 jiffies per core doing this measurement (0-2 on jiffie edge alignment, and 4 on measurement). The timing loop was based on raid6_choose_gen(), which uses (16+1)*N jiffies (where N is the number of algorithms). By taking only the fastest iteration out of all attempts for use in the comparison, variance between runs is very low. On my THead C906, it looks like this: [ 0.047563] cpu0: Ratio of byte access time to unaligned word access is 4.34, unaligned accesses are fast Several others have chimed in with results on slow machines with the older algorithm, which took all runs into account, including noise like interrupts. Even with this variation, results indicate that in all cases (fast, slow, and emulated) the measured numbers are nowhere near each other (always multiple factors away). * b4-shazam-merge: RISC-V: alternative: Remove feature_probe_func RISC-V: Probe for unaligned access speed Link: https://lore.kernel.org/r/20230818194136.4084400-1-evan@rivosinc.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com> 08 September 2023, 18:24:12 UTC

Unlike the set_memory_xx() variants they take void pointer start and end parameters, which allows using them without the usual casts, and also to use them on areas larger than 8TB. Note that the set_memory_xx() family comes with an int num_pages parameter which overflows with 8TB. This could be addressed by changing the num_pages parameter to unsigned long, however requires to change all architectures, since the module code expects an int parameter (see module_set_memory()). This was indeed an issue since for debug_pagealloc() we call set_memory_4k() on the whole identity mapping.

9013c51 Linus Torvalds 03 September 2023, 20:08:03 UTC vfs: mostly undo glibc turning 'fstat()' into 'fstatat(AT_EMPTY_PATH)' Mateusz reports that glibc turns 'fstat()' calls into 'fstatat()', and that seems to have been going on for quite a long time due to glibc having tried to simplify its stat logic into just one point. This turns out to cause completely unnecessary overhead, where we then go off and allocate the kernel side pathname, and actually look up the empty path. Sure, our path lookup is quite optimized, but it still causes a fair bit of allocation overhead and a couple of completely unnecessary rounds of lockref accesses etc. This is all hopefully getting fixed in user space, and there is a patch floating around for just having glibc use the native fstat() system call. But even with the current situation we can at least improve on things by catching the situation and short-circuiting it. Note that this is still measurably slower than just a plain 'fstat()', since just checking that the filename is actually empty is somewhat expensive due to inevitable user space access overhead from the kernel (ie verifying pointers, and SMAP on x86). But it's still quite a bit faster than actually looking up the path for real. To quote numers from Mateusz: "Sapphire Rapids, will-it-scale, ops/s stock fstat 5088199 patched fstat 7625244 (+49%) real fstat 8540383 (+67% / +12%)" where that 'stock fstat' is the glibc translation of fstat into fstatat() with an empty path, the 'patched fstat' is with this short circuiting of the path lookup, and the 'real fstat' is the actual native fstat() system call with none of this overhead.

If we want to use any of the commands to configure tc, We must use the other command to clear the existing configuration. However, when we configure a single tc with tc qdisc, we can still configure it with dcb ets. Because we use mqprio_active as the tag of tc qdisc configuration, but with dcb ets, we do not check mqprio_active.

The suggested workaround is to clear advertisement of EEE for PHYs in this chip driver. To avoid regressions with other switch ICs the new MICREL_NO_EEE flag has been introduced. Moreover, the in-register disablement of MMD_DEVICE_ID_EEE_ADV.MMD_EEE_ADV MMD register is removed, as this code is both; now executed too late (after previous rework of the PHY and DSA for KSZ switches) and not required as setting all members of eee_broken_modes bit field prevents the KSZ9477 from advertising EEE.

081690e Srinivas Pandruvada 06 September 2023, 19:08:16 UTC powercap: intel_rapl: Fix invalid setting of Power Limit 4 System runs at minimum performance, once powercap RAPL package domain enabled flag is changed from 1 to 0 to 1. Setting RAPL package domain enabled flag to 0, results in setting of power limit 4 (PL4) MSR 0x601 to 0. This implies disabling PL4 limit. The PL4 limit controls the peak power. So setting 0, results in some undesirable performance, which depends on hardware implementation. Even worse, when the enabled flag is set to 1 again. This will set PL4 MSR value to 0x01, which means reduce peak power to 0.125W. This will force system to run at the lowest possible performance on every PL4 supported system. Setting enabled flag should only affect the "enable" bit, not other bits. Here it is changing power limit. This is caused by a change which assumes that there is an enable bit in the PL4 MSR like other power limits. Although PL4 enable/disable bit is present with TPMI RAPL interface, it is not present with the MSR interface. There is a rapl_primitive_info defined for non existent PL4 enable bit and then it is used with the commit 9050a9cd5e4c ("powercap: intel_rapl: Cleanup Power Limits support") to enable PL4. This is wrong, hence remove this rapl primitive for PL4. Also in the function rapl_detect_powerlimit(), PL_ENABLE is used to check for the presence of power limits. Replace PL_ENABLE with PL_LIMIT, as PL_LIMIT must be present. Without this change, PL4 controls will not be available in the sysfs once rapl primitive for PL4 is removed.

The list of things which don't work with encryption should be fairly short, mostly around the edges: fallocate (not supported well in CephFS to begin with), copy_file_range (requires re-encryption), non-default striping patterns.

ab41a97 Will Deacon 06 September 2023, 18:15:37 UTC arm64/sysreg: Fix broken strncpy() -> strscpy() conversion Mostafa reports that commit d232606773a0 ("arm64/sysreg: refactor deprecated strncpy") breaks our early command-line parsing because the original code is working on space-delimited substrings rather than NUL-terminated strings. Rather than simply reverting the broken conversion patch, replace the strscpy() with a simple memcpy() with an explicit NUL-termination of the result.
