2024-09-06perf: Add driver for Arm NI-700 interconnect PMURobin Murphy3-0/+789
The Arm NI-700 Network-on-Chip Interconnect has a relatively straightforward design with a hierarchy of voltage, power, and clock domains, where each clock domain then contains a number of interface units and a PMU which can monitor events thereon. As such, it begets a relatively straightforward driver to interface those PMUs with perf. Even more so than with arm-cmn, users will require detailed knowledge of the wider system topology in order to meaningfully analyse anything, since the interconnect itself cannot know what lies beyond the boundary of each inscrutably-numbered interface. Given that, for now they are also expected to refer to the NI-700 documentation for the relevant event IDs to provide as well. An identifier is implemented so we can come back and add jevents if anyone really wants to.

2024-09-06wifi: mac80211: handle ieee80211_radar_detected() for MLOAditya Kumar Singh13-15/+15
Currently DFS works under assumption there could be only one channel context in the hardware. Hence, drivers just calls the function ieee80211_radar_detected() passing the hardware structure. However, with MLO, this obviously will not work since number of channel contexts will be more than one and hence drivers would need to pass the channel information as well on which the radar is detected. Also, when radar is detected in one of the links, other link's CAC should not be cancelled. Hence, in order to support DFS with MLO, do the following changes - * Add channel context conf pointer as an argument to the function ieee80211_radar_detected(). During MLO, drivers would have to pass on which channel context conf radar is detected. Otherwise, drivers could just pass NULL. * ieee80211_radar_detected() will iterate over all channel contexts present and * if channel context conf is passed, only mark that as radar detected * if NULL is passed, then mark all channel contexts as radar detected * Then as usual, schedule the radar detected work. * In the worker, go over all the contexts again and for all such context which is marked with radar detected, cancel the ongoing CAC by calling ieee80211_dfs_cac_cancel() and then notify cfg80211 via cfg80211_radar_event(). * To cancel the CAC, pass the channel context as well where radar is detected to ieee80211_dfs_cac_cancel(). This ensures that CAC is canceled only on the links using the provided context, leaving other links unaffected. This would also help in scenarios where there is split phy 5 GHz radio, which is capable of DFS channels in both lower and upper band. In this case, simultaneous radars can be detected.

2024-09-06wifi: cfg80211: handle DFS per linkAditya Kumar Singh4-8/+9
Currently, during starting a radar detection, no link id information is parsed and passed down. In order to support starting radar detection during Multi Link Operation, it is required to pass link id as well. Add changes to first parse and then pass link id in the start radar detection path. Additionally, update notification APIs to allow drivers/mac80211 to pass the link ID. However, everything is handled at link 0 only until all API's are ready to handle it per link.

A few members related to DFS handling are currently under per wireless device data structure. However, in order to support DFS with MLO, there is a need to have them on a per-link manner. Hence, as a preliminary step, move members cac_started, cac_start_time and cac_time_ms to be on a per-link basis. Since currently, link ID is not known at all places, use default value of 0 for now.

2024-09-06dm-integrity: fix a race condition when accessing recalc_sectorMikulas Patocka1-1/+3
There's a race condition when accessing the variable ic->sb->recalc_sector. The function integrity_recalc writes to this variable when it makes some progress and the function dm_integrity_map_continue may read this variable concurrently. One problem is that on 32-bit architectures the 64-bit variable is not read and written atomically - it may be possible to read garbage if read races with write. Another problem is that memory accesses to this variable are not guarded with memory barriers. This commit fixes the race - it moves reading ic->sb->recalc_sector to an earlier place where we hold &ic->endio_wait.lock. Signed-off-by: Mikulas Patocka <[email protected]> Cc: [email protected]
2024-09-06dm-integrity: support recalculation in the 'I' modeMikulas Patocka1-42/+246
In the kernel 6.11, dm-integrity was enhanced with an inline ('I') mode. This mode uses devices with non-power-of-2 sector size. The extra metadata after each sector are used to hold the integrity hash. This commit enhances the inline mode, so that there is automatic recalculation of the integrity hashes when the 'reclaculate' parameter is used. It allows us to activate the device instantly, and the recalculation is done on background. If the device is deactivated while recalculation is in progress, it will remember the point where it stopped and it will continue from this point when activated again.

2024-09-06media: atomisp: Improve binary finding debug loggingHans de Goede1-161/+95
The atomisp firmware contains a number of different pipeline binaries inside its firmware file and the driver selects the right one depending on the selected pipeline configuration. Sometimes (e.g. when the selected output resolution is too big) it fails to find a binary. This happens especially when adding support for new sensors. Improve the logging when this happens to make debugging easier: 1. Replace ia_css_debug_dtrace(IA_CSS_DEBUG_TRACE, ...) with standard dev_dbg() calls so that the logs can be enabled with dyndbg 2. Do not dump_stack() when this fails, doing so adds no useful extra info 3. With the dump_stack() call gone, remove the wrapper and rename __ia_css_binary_find() to ia_css_binary_find() 4. On error use dev_err() instead of dev_dbg() so that when things fail it is clear why they fail without needing to enable dyndbg Signed-off-by: Hans de Goede <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Mauro Carvalho Chehab <[email protected]>
