2022-09-28tracing: Wake up ring buffer waiters on closing of the fileSteven Rostedt (Google)
When the file that represents the ring buffer is closed, there may be waiters waiting on more input from the ring buffer. Call ring_buffer_wake_waiters() to wake up any waiters when the file is closed.

2022-09-28ring-buffer: Add ring_buffer_wake_waiters()Steven Rostedt (Google)
On closing of a file that represents a ring buffer or flushing the file, there may be waiters on the ring buffer that needs to be woken up and exit the ring_buffer_wait() function. Add ring_buffer_wake_waiters() to wake up the waiters on the ring buffer and allow them to exit the wait loop.

2022-09-28clk: sunxi-ng: h6: Fix default PLL GPU rateJernej Skrabec
In commit 4167ac8a657e ("clk: sunxi-ng: sun50i: h6: Modify GPU clock configuration to support DFS") divider M0 was forced to be 1 in order to support DFS. However, that left N as it is, at high value of 36. On boards without devfreq enabled (all of them in kernel 6.0), this effectively sets GPU frequency to 864 MHz. This is about 100 MHz above maximum supported frequency. In order to fix this, let's set N to 18 (register value 17). That way default frequency of 432 MHz is preserved.

2022-09-28Merge branch 'Parameterize task iterators.'Andrii Nakryiko
Kui-Feng Lee says: ==================== Allow creating an iterator that loops through resources of one task/thread. People could only create iterators to loop through all resources of files, vma, and tasks in the system, even though they were interested in only the resources of a specific task or process. Passing the additional parameters, people can now create an iterator to go through all resources or only the resources of a task. Major Changes: - Add new parameters in bpf_iter_link_info to indicate to go through all tasks or to go through a specific task. - Change the implementations of BPF iterators of vma, files, and tasks to allow going through only the resources of a specific task. - Provide the arguments of parameterized task iterators in bpf_link_info. Differences from v10: - Check pid_alive() to avoid potential errors. Differences from v9: - Fix the boundary check of computing page_shift. - Rewording the reason of checking and returning the same task. Differences from v8: - Fix uninitialized variable. - Avoid redundant work of getting task from pid. - Change format string to use %u instead of %d. - Use the value of page_shift to compute correct offset in bpf_iter_vm_offset.c. Differences from v7: - Travel the tasks of a process through task_group linked list instead of traveling through the whole namespace. Differences from v6: - Add part 5 to make bpftool show the value of parameters. - Change of wording of show_fdinfo() to show pid or tid instead of always pid. - Simplify error handling and naming of test cases. Differences from v5: - Use user-space tid/pid terminologies in bpf_iter_link_info and bpf_link_info. - Fix reference count - Merge all variants to one 'u32 pid' in internal structs. (bpf_iter_aux_info and bpf_iter_seq_task_common) - Compare the result of get_uprobe_offset() with the implementation with the vma iterators. - Implement show_fdinfo. Differences from v4: - Remove 'type' from bpf_iter_link_info and bpf_link_info. v10: https://lore.kernel.org/all/20220831181039.2680134-1-kuifeng@fb.com/ v9: https://lore.kernel.org/bpf/20220829192317.486946-1-kuifeng@fb.com/ v8: https://lore.kernel.org/bpf/20220829192317.486946-1-kuifeng@fb.com/ v7: https://lore.kernel.org/bpf/20220826003712.2810158-1-kuifeng@fb.com/ v6: https://lore.kernel.org/bpf/20220819220927.3409575-1-kuifeng@fb.com/ v5: https://lore.kernel.org/bpf/20220811001654.1316689-1-kuifeng@fb.com/ v4: https://lore.kernel.org/bpf/20220809195429.1043220-1-kuifeng@fb.com/ v3: https://lore.kernel.org/bpf/20220809063501.667610-1-kuifeng@fb.com/ v2: https://lore.kernel.org/bpf/20220801232649.2306614-1-kuifeng@fb.com/ v1: https://lore.kernel.org/bpf/20220726051713.840431-1-kuifeng@fb.com/ ==================== Signed-off-by: Andrii Nakryiko <andrii@kernel.org>
2022-09-28bpftool: Show parameters of BPF task iterators.Kui-Feng Lee
Show tid or pid of iterators if giving an argument of tid or pid For example, the command `bpftool link list` may list following lines. 1: iter prog 2 target_name bpf_map 2: iter prog 3 target_name bpf_prog 33: iter prog 225 target_name task_file tid 1644 pids test_progs(1644) Link 33 is a task_file iterator with tid 1644. For now, only targets of task, task_file and task_vma may be with tid or pid to filter out tasks other than those belonging to a process (pid) or a thread (tid).

2022-09-28bpf: Handle show_fdinfo for the parameterized task BPF iteratorsKui-Feng Lee
Show information of iterators in the respective files under /proc/<pid>/fdinfo/. For example, for a task file iterator with 1723 as the value of tid parameter, its fdinfo would look like the following lines. pos: 0 flags: 02000000 mnt_id: 14 ino: 38 link_type: iter link_id: 51 prog_tag: a590ac96db22b825 prog_id: 299 target_name: task_file task_type: TID tid: 1723 This patch add the last three fields. task_type is the type of the task parameter. TID means the iterator visit only the thread specified by tid. The value of tid in the above example is 1723. For the case of PID task_type, it means the iterator visits only threads of a process and will show the pid value of the process instead of a tid.

2022-09-29kbuild: hide error checker logs for V=1 buildsMasahiro Yamada
V=1 (verbose build) shows commands executed by Make, but it may cause misunderstanding. For example, the following command shows the outstanding error message. $ make V=1 INSTALL_PATH=/tmp install test -e include/generated/autoconf.h -a -e include/config/auto.conf || ( \ echo >&2; \ echo >&2 " ERROR: Kernel configuration is invalid."; \ echo >&2 " include/generated/autoconf.h or include/config/auto.conf are missing.";\ echo >&2 " Run 'make oldconfig && make prepare' on kernel src to fix it."; \ echo >&2 ; \ /bin/false) unset sub_make_done; ./scripts/install.sh It is not an error. Make just showed the recipe lines it has executed, but people may think that 'make install' has failed. Likewise, the combination of V=1 and O= shows confusing "*** The source tree is not clean, please run 'make mrproper'". Suppress such misleading logs.

2022-09-28ARM: dts: uniphier: Remove compatible "snps,dw-pcie-ep" from pcie-ep nodeKunihiko Hayashi
The generic platform driver pcie-designware-plat.c doesn't work for UniPhier PCIe endpoint controller, because the controller has some necessary initialization sequence for the controller-specific logic. Currently the controller doesn't use "snps,dw-pcie-ep" compatible, so this is no longer needed. Remove the compatible string from the pcie-ep node.

2022-09-28ARM: Drop CMDLINE_* dependency on ATAGSGeert Uytterhoeven
On arm32, the configuration options to specify the kernel command line type depend on ATAGS. However, the actual CMDLINE cofiguration option does not depend on ATAGS, and the code that handles this is not specific to ATAGS (see drivers/of/fdt.c:early_init_dt_scan_chosen()). Hence users who desire to override the kernel command line on arm32 must enable support for ATAGS, even on a pure-DT system. Other architectures (arm64, loongarch, microblaze, nios2, powerpc, and riscv) do not impose such a restriction. Hence drop the dependency on ATAGS.

2022-09-28ARM: Drop CMDLINE_FORCE dependency on !ARCH_MULTIPLATFORMGeert Uytterhoeven
On older platforms that boot an image with an appended DTB, or where the boot loader has no support for updating chosen/bootargs, it is common to rely on CMDLINE_FORCE. While a fixed command line can make the kernel unbootable on other platforms, it is not guaranteed to cause that. E.g. all Renesas boards use the same chosen/bootargs in upstream DTS, which works fine if your DHCP server hands out proper nfsroot parameters.
