2024-03-04btrfs: remove the pg_offset parameter from btrfs_get_extent()Qu Wenruo
The parameter @pg_offset of btrfs_get_extent() is only utilized for inlined extent, and we already have an ASSERT() and tree-checker, to make sure we can only get inline extent at file offset 0. Any invalid inline extent with non-zero file offset would be rejected by tree-checker in the first place. Thus the @pg_offset parameter is not really necessary, just remove it.

2024-03-04spi: dt-bindings: samsung: make dma properties not requiredTudor Ambarus
Since the addition of the driver in 2009, the driver selects between DMA and polling mode depending on the transfer length - DMA mode for transfers bigger than the FIFO depth, polling mode otherwise. All versions of the IP support polling mode, make the dma properties not required.

2024-03-04regulator: rk808: fix LDO range on RK806Quentin Schulz
The linear ranges aren't really matching what they should be. Indeed, the range is inclusive of the min value, so it makes sense the previous range does NOT include the max step value representing the min value of the range in question. Since 3.4V is represented by the decimal value 232, the previous range max step value should be 231 and not 232. No expected change in behavior since 3.4V was mapped with step 232 from the first range but is now mapped with step 232 from the second range. While at it, remove the incorrect comment from the second range.

2024-03-04regulator: rk808: fix buck range on RK806Quentin Schulz
The linear ranges aren't really matching what they should be. Indeed, the range is inclusive of the min value, so it makes sense the previous range does NOT include the max step value representing the min value of the range in question. Since 1.5V is represented by the decimal value 160, the previous range max step value should be 159 and not 160. Similarly, 3.4V is represented by the decimal value 236, so the previous range max value should be 235 and not 237. The only change in behavior this makes is that this actually modeled the ranges to map step with decimal value 237 with 3.65V instead of 3.4V (the max supported by the HW).

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI updates for v6.9 Quite a few changes to extend support to SCMI v3.2 specification, to enhance notification handling and other miscellaneous updates. 1. Enhancements to notification handling Until now, trying to register a notifier for an unsuppported notification returned an error genrating unneeded message exchanges with the SCMI platform. This can be avoided by looking up in advance the specific protocol and resources available. With these changes SCMI driver user will fail to register a notifier if the related command or resource is not supported (like before) without the need of exchanging any message. Perf notifications are also extended to provide the pre-calculated frequencies corresponding to the level or index carried by the 2. More SCMI v3.2 related updates One of the main addition includes a centralized support to the SCMI core to handle v3.2 optional protocol version negotiation, so that at protocol initialization time, if the platform advertised version is newer than supported by the kernel and protocol version negotiation is supported, the SCMI core will attempt to negotiate an older protocol version. It also includes the clock get permissions which indicates if any of the clock operations are forbidden by the platform for the OSPM agent. It can be used in the clock driver to avoid unnecessary message exchanges between the kernel and the platform which will always end up with the failure. It also includes other missing bits of clock v3.2 protocol so that the supported protocol version can be bumped to 0x30000 (v3.2). 3. Miscellaneous updates This includes addition of warning if the domain frequency multiplier is 0 or rounded off to indicate the actual frequencies are either wrong ot rounded off, hardening of clock domain info lookups, addition of multiple protocols registration support within a SCMI driver, update to SCMI entry in MAINTAINERS to include HWMON driver and constifying the scmi_bus_type structure. This also includes couple for fixes to minor issues: double free in SMC transport cleanup path and struct kernel-doc warnings in optee transport. * tag 'scmi-updates-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: (29 commits) MAINTAINERS: Update SCMI entry with HWMON driver firmware: arm_scmi: Update the supported clock protocol version firmware: arm_scmi: Add standard clock OEM definitions firmware: arm_scmi: Add clock check for extended config support firmware: arm_scmi: Add support for v3.2 NEGOTIATE_PROTOCOL_VERSION firmware: arm_scmi: Fix struct kernel-doc warnings in optee transport firmware: arm_scmi: Report frequencies in the perf notifications firmware: arm_scmi: Use opps_by_lvl to store opps firmware: arm_scmi: Implement is_notify_supported callback in powercap protocol firmware: arm_scmi: Implement is_notify_supported callback in reset protocol firmware: arm_scmi: Implement is_notify_supported callback in sensor protocol firmware: arm_scmi: Implement is_notify_supported callback in clock protocol firmware: arm_scmi: Implement is_notify_supported callback in system power protocol firmware: arm_scmi: Implement is_notify_supported callback in power protocol firmware: arm_scmi: Implement is_notify_supported callback in perf protocol firmware: arm_scmi: Add a common helper to check if a message is supported firmware: arm_scmi: Check for notification support firmware: arm_scmi: Make scmi_bus_type const firmware: arm_scmi: Fix double free in SMC transport cleanup path firmware: arm_scmi: Implement clock get permissions ...

2024-03-04selftests/bpf: xdp_hw_metadata reduce sleep intervalSong Yoong Siang
In current ping-pong design, xdp_hw_metadata will wait until the packet transmission completely done, then only start to receive the next packet. The current sleep interval is 10ms, which is unnecessary large. Typically, a NIC does not need such a long time to transmit a packet. Furthermore, during this 10ms sleep time, the app is unable to receive incoming packets. Therefore, this commit reduce sleep interval to 10us, so that xdp_hw_metadata is able to support periodic packets with shorter interval. 10us * 500 = 5ms should be enough for packet transmission and status retrieval.

2024-03-04selftests/bpf: Extend uprobe/uretprobe triggering benchmarksAndrii Nakryiko
Settle on three "flavors" of uprobe/uretprobe, installed on different kinds of instruction: nop, push, and ret. All three are testing different internal code paths emulating or single-stepping instructions, so are interesting to compare and benchmark separately. To ensure `push rbp` instruction we ensure that uprobe_target_push() is not a leaf function by calling (global __weak) noop function and returning something afterwards (if we don't do that, compiler will just do a tail call optimization). Also, we need to make sure that compiler isn't skipping frame pointer generation, so let's add `-fno-omit-frame-pointers` to Makefile. Just to give an idea of where we currently stand in terms of relative performance of different uprobe/uretprobe cases vs a cheap syscall (getpgid()) baseline, here are results from my local machine: $ benchs/run_bench_uprobes.sh base : 1.561 ± 0.020M/s uprobe-nop : 0.947 ± 0.007M/s uprobe-push : 0.951 ± 0.004M/s uprobe-ret : 0.443 ± 0.007M/s uretprobe-nop : 0.471 ± 0.013M/s uretprobe-push : 0.483 ± 0.004M/s uretprobe-ret : 0.306 ± 0.007M/s Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Link: https://lore.kernel.org/bpf/20240301214551.1686095-1-andrii@kernel.org

2024-03-04wifi: mac80211: introduce a feature flag for quiet in CSAJohannes Berg
When doing CSA in multi-link, there really isn't a need to stop transmissions entirely. Add a feature flag for drivers to indicate they can handle quiet in CSA (be it by parsing themselves, or by implementing drv_pre_channel_switch()), to make that possible. Also clean up the csa_block_tx handling: it clearly cannot handle multi-link due to the way queues are stopped, move it to the sdata. Drivers should be doing it themselves for working properly during CSA in MLO anyway. Also rename it to indicate that it reflects TX was blocked at mac80211.

If we just want to determine the length of the fragmented data, we basically need the same logic, and really we want it to be _literally_ the same logic, so it cannot be out of sync in any way. Allow calling cfg80211_defragment_element() without an output buffer, where it then just returns the required output size. Also add this to the tests, just to exercise it, using the pre-calculated length to really do the defragmentation, which checks that this is sufficient.
