2022-03-18media: platform/*/Kconfig: make manufacturer menus more uniformMauro Carvalho Chehab19-33/+53
Do some adjustments at the per-vendor Kconfig, adding a comment at the beginning in order to identify the manufacturer, and adjust a few entries to make them look more uniform.

2022-03-18media: platform: re-structure TI driversPratyush Yadav20-10/+9
The ti-vpe/ sub-directory does not only contain the VPE-specific things. It also contains the CAL driver, which is a completely different subsystem. This is also not a good place to add new drivers for other TI platforms since they will all get mixed up. Separate the VPE and CAL parts into different sub-directories and rename the ti-vpe/ sub-directory to ti/. This is now the place where new TI platform drivers can be added.

2022-03-17Merge branch 'bpf: Add kprobe multi link'Alexei Starovoitov21-44/+1302
Jiri Olsa says: ==================== hi, this patchset adds new link type BPF_TRACE_KPROBE_MULTI that attaches kprobe program through fprobe API [1] instroduced by Masami. The fprobe API allows to attach probe on multiple functions at once very fast, because it works on top of ftrace. On the other hand this limits the probe point to the function entry or return. With bpftrace support I see following attach speed: # perf stat --null -r 5 ./src/bpftrace -e 'kprobe:x* { } i:ms:1 { exit(); } ' Attaching 2 probes... Attaching 3342 functions ... 1.4960 +- 0.0285 seconds time elapsed ( +- 1.91% ) v3 changes: - based on latest fprobe post from Masami [2] - add acks - add extra comment to kprobe_multi_link_handler wrt entry ip setup [Masami] - keep swap_words_64 static and swap values directly in bpf_kprobe_multi_cookie_swap [Andrii] - rearrange locking/migrate setup in kprobe_multi_link_prog_run [Andrii] - move uapi fields [Andrii] - add bpf_program__attach_kprobe_multi_opts function [Andrii] - many small test changes [Andrii] - added tests for bpf_program__attach_kprobe_multi_opts - make kallsyms_lookup_name check for empty string [Andrii] v2 changes: - based on latest fprobe changes [1] - renaming the uapi interface to kprobe multi - adding support for sort_r to pass user pointer for swap functions and using that in cookie support to keep just single functions array - moving new link to kernel/trace/bpf_trace.c file - using single fprobe callback function for entry and exit - using kvzalloc, libbpf_ensure_mem functions - adding new k[ret]probe.multi sections instead of using current kprobe - used glob_match from test_progs.c, added '?' matching - move bpf_get_func_ip verifier inline change to seprate change - couple of other minor fixes Also available at: https://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git bpf/kprobe_multi thanks, jirka [1] https://lore.kernel.org/bpf/164458044634.586276.3261555265565111183.stgit@devnote2/ [2] https://lore.kernel.org/bpf/164735281449.1084943.12438881786173547153.stgit@devnote2/ ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>

These 3 options are mutually exclusive. When using symbols or addresses, user can also provide cookie value for each symbol/address that can be retrieved later in bpf program with bpf_get_attach_cookie helper. struct bpf_kprobe_multi_opts { size_t sz; const char **syms; const unsigned long *addrs; const __u64 *cookies; size_t cnt; bool retprobe; size_t :0; }; Symbols, addresses and cookies are provided through opts object (syms/addrs/cookies) as array pointers with specified count (cnt). Each cookie value is paired with provided function address or symbol with the same array index. The program can be also attached as return probe if 'retprobe' is set. For quick usage with NULL opts argument, like: bpf_program__attach_kprobe_multi_opts(prog, "ksys_*", NULL) the 'prog' will be attached as kprobe to 'ksys_*' functions. Also adding new program sections for automatic attachment: kprobe.multi/<symbol_pattern> kretprobe.multi/<symbol_pattern> The symbol_pattern is used as 'pattern' argument in bpf_program__attach_kprobe_multi_opts function.
