2022-07-08usb: core: hub: Create platform devices for onboard hubs in hub_probe()Matthias Kaehlcke2-1/+9
Call onboard_hub_create/destroy_pdevs() from hub_probe/disconnect() to create/destroy platform devices for onboard USB hubs that may be connected to the hub. The onboard hubs must have nodes in the device tree. onboard_hub_create/destroy_pdevs() are NOPs unless CONFIG_USB_ONBOARD_HUB=y/m. Also add a field to struct usb_hub to keep track of the onboard hub platform devices that are owned by the hub.

2022-07-08usb: misc: Add onboard_usb_hub driverMatthias Kaehlcke9-0/+641
The main issue this driver addresses is that a USB hub needs to be powered before it can be discovered. For discrete onboard hubs (an example for such a hub is the Realtek RTS5411) this is often solved by supplying the hub with an 'always-on' regulator, which is kind of a hack. Some onboard hubs may require further initialization steps, like changing the state of a GPIO or enabling a clock, which requires even more hacks. This driver creates a platform device representing the hub which performs the necessary initialization. Currently it only supports switching on a single regulator, support for multiple regulators or other actions can be added as needed. Different initialization sequences can be supported based on the compatible string. Besides performing the initialization the driver can be configured to power the hub off during system suspend. This can help to extend battery life on battery powered devices which have no requirements to keep the hub powered during suspend. The driver can also be configured to leave the hub powered when a wakeup capable USB device is connected when suspending, and power it off otherwise. Technically the driver consists of two drivers, the platform driver described above and a very thin USB driver that subclasses the generic driver. The purpose of this driver is to provide the platform driver with the USB devices corresponding to the hub(s) (a hub controller may provide multiple 'logical' hubs, e.g. one to support USB 2.0 and another for USB 3.x).

2022-07-08dt-bindings: usb: rts5411: Rename property 'companion-hub' to 'peer-hub'Matthias Kaehlcke1-5/+5
In the context of USB the term 'companion-hub' is misleading, change the name of the property to 'peer-hub'. There are no upstream users of the 'companion-hub' property, neither in the device tree, nor on the driver side, so renaming it shouldn't cause any compatibility issues with existing device trees.

2022-07-08USB: gadget: udc: tracing: Do not open code __string() with __dynamic_array()Steven Rostedt (Google)1-4/+4
The event classes udc_log_ep and udc_log_req both declare: __dynamic_array(char, name, UDC_TRACE_STR_MAX) Which will reserve UDC_TRACE_STR_MAX bytes on the ring buffer for the event to write in name. It then uses snprintf() to write into that space. Assuming that the string being copied is nul terminated, it is better to just use the __string() helper. That way only the size of the string is saved into the ring buffer and not the max size (yes, the entire UDC_TRACE_STR_MAX is used in the trace event, and anything not used is just junk in the ring buffer). Worse, there's also meta data saved into the event that denotes where the string is stored in the event and also saves its size, which is always going to be UDC_TRACE_STR_MAX. Convert both to use the __string() and __assign_str() helpers that are for this kind of use case.

All of the clocks listed in the binding are always wired to the XHCI controller hardware blocks on all SoCs. The reason some clocks were made optional in the binding was to account for the fact that depending on the SoC, some of the clocks might be fixed (ie not controlled by software). Given that the devicetree should represent the hardware, make all clocks required in the binding. Subsequent patches will make the DTS changes to specify fixed-clocks for the clocks that aren't controllable. Signed-off-by: Nícolas F. R. A.

Committer notes: And here is a refresher about the 'ignore_missing_thread' knob, from a previous patch using it: ca8000684ec4e66f ("perf evsel: Enable ignore_missing_thread for pid option") --- While monitoring a multithread process with pid option, perf sometimes may return sys_perf_event_open failure with 3(No such process) if any of the process's threads die before we open the event. However, we want perf continue monitoring the remaining threads and do not exit with error. --- Signed-off-by: Gang Li <ligang.bdlg@bytedance.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: https://lore.kernel.org/r/20220622030037.15005-1-ligang.bdlg@bytedance.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2022-06-26perf inject: Adjust output data offset for backward compatibilityRaul Silvera3-1/+17
When 'perf inject' creates a new file, it reuses the data offset from the input file. If there has been a change on the size of the header, as happened in v5.12 -> v5.13, the new offsets will be wrong, resulting in a corrupted output file. This change adds the function perf_session__data_offset to compute the data offset based on the current header size, and uses that instead of the offset from the original input file.

2022-06-26perf build-id: Fix caching files with a wrong build IDAdrian Hunter1-0/+28
Build ID events associate a file name with a build ID. However, when using perf inject, there is no guarantee that the file on the current machine at the current time has that build ID. Fix by comparing the build IDs and skip adding to the cache if they are different. Example: $ echo "int main() {return 0;}" > prog.c $ gcc -o prog prog.c $ perf record --buildid-all ./prog [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.019 MB perf.data ] $ file-buildid() { file $1 | awk -F= '{print $2}' | awk -F, '{print $1}' ; } $ file-buildid prog 444ad9be165d8058a48ce2ffb4e9f55854a3293e $ file-buildid ~/.debug/$(pwd)/prog/444ad9be165d8058a48ce2ffb4e9f55854a3293e/elf 444ad9be165d8058a48ce2ffb4e9f55854a3293e $ echo "int main() {return 1;}" > prog.c $ gcc -o prog prog.c $ file-buildid prog 885524d5aaa24008a3e2b06caa3ea95d013c0fc5 Before: $ perf buildid-cache --purge $(pwd)/prog $ perf inject -i perf.data -o junk $ file-buildid ~/.debug/$(pwd)/prog/444ad9be165d8058a48ce2ffb4e9f55854a3293e/elf 885524d5aaa24008a3e2b06caa3ea95d013c0fc5 $ After: $ perf buildid-cache --purge $(pwd)/prog $ perf inject -i perf.data -o junk $ file-buildid ~/.debug/$(pwd)/prog/444ad9be165d8058a48ce2ffb4e9f55854a3293e/elf $ Fixes: 454c407ec17a0c63 ("perf: add perf-inject builtin") Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Tom Zanussi <tzanussi@gmail.com> Link: https://lore.kernel.org/r/20220621125144.5623-1-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
