2024-11-12ufs: ufs_sb_private_info: remove unused s_{2,3}apb fieldsAgathe Porte
These two fields are populated and stored as a "frequently used value" in ufs_fill_super, but are not used afterwards in the driver. Moreover, one of the shifts triggers UBSAN: shift-out-of-bounds when apbshift is 12 because 12 * 3 = 36 and 1 << 36 does not fit in the 32 bit integer used to store the value.

When calculating the physical address range based on the iotlb and mr [start,end) ranges, the offset of mr->start relative to map->start is not taken into account. This leads to some incorrect and duplicate mappings. For the case when mr->start < map->start the code is already correct: the range in [mr->start, map->start) was handled by a different iteration.

2024-11-12srcu: Check for srcu_read_lock_lite() across all CPUsPaul E. McKenney
If srcu_read_lock_lite() is used on a given srcu_struct structure, then the grace-period processing must do synchronize_rcu() instead of smp_mb() between the scans of the ->srcu_unlock_count[] and ->srcu_lock_count[] counters. Currently, it does that by testing the SRCU_READ_FLAVOR_LITE bit of the ->srcu_reader_flavor mask, which works well. But only if the CPU running that srcu_struct structure's grace period has previously executed srcu_read_lock_lite(), which might not be the case, especially just after that srcu_struct structure has been created and initialized. This commit therefore updates the srcu_readers_unlock_idx() function to OR together the ->srcu_reader_flavor masks from all CPUs, and then make the srcu_readers_active_idx_check() function that test the SRCU_READ_FLAVOR_LITE bit in the resulting mask. Note that the srcu_readers_unlock_idx() function is already scanning all the CPUs to sum up the ->srcu_unlock_count[] fields and that this is on the grace-period slow path, hence no concerns about the small amount of extra work.

2024-11-12rcutorture: Avoid printing cpu=-1 for no-fault RCU boost failurePaul E. McKenney
If a CPU runs throughout the stalled grace period without passing through a quiescent state, RCU priority boosting cannot help. The rcu_torture_boost_failed() function therefore prints a message flagging the first such CPU. However, if the stall was instead due to (for example) RCU's grace-period kthread being starved of CPU, there will be no such CPU, causing rcu_check_boost_fail() to instead pass back -1 through its cpup CPU-pointer parameter. Therefore, the current message complains about a mythical CPU -1. This commit therefore checks for this situation, and notes that all CPUs have passed through a quiescent state.

2024-11-12rcuscale: Add guest_os_delay module parameterPaul E. McKenney
This commit adds a guest_os_delay module parameter that extends warm-up and cool-down the specified number of seconds before and after the series of test runs. This allows the data-collection intervals from any given rcuscale guest OSes to line up with active periods in the other rcuscale guest OSes, and also allows the thermal warm-up period required to obtain consistent results from one test to the next.

In performance tests, it can be counter-productive to spread torture-test guest OSes across sockets. Plus the experimenter might have ideas about what CPUs individual guest OSes are to run on.

2024-11-12hwmon: (pwm-fan) Introduce start from stopped state handlingMarek Vasut
Delta AFC0612DB-F00 fan has to be set to at least 30% PWM duty cycle to spin up from a stopped state, and can be afterward throttled down to lower PWM duty cycle. Introduce support for operating such fans which need to start at higher PWM duty cycle first and can slow down next. Introduce two new DT properties, "fan-stop-to-start-percent" and "fan-stop-to-start-us". The former describes the minimum percent of fan RPM at which it will surely spin up from stopped state. This value can be found in the fan datasheet and can be converted to PWM duty cycle easily. The "fan-stop-to-start-us" describes the minimum time in microseconds for which the fan has to be set to stopped state start RPM for the fan to surely spin up. Adjust the PWM setting code such that if the PWM duty cycle is below the minimum duty cycle needed by the fan to spin up from stopped state, then first set the PWM duty cycle to the minimum duty cycle needed by the fan to spin up from stopped state, then wait the time necessary for the fan to spin up from stopped state, and finally set the PWM duty cycle to the one desired by user.
