2025-09-21clk: clocking-wizard: Fix output clock register offset for Versal platformsShubhrajyoti Datta
The output clock register offset used in clk_wzrd_register_output_clocks was incorrectly referencing 0x3C instead of 0x38, which caused misconfiguration of output dividers on Versal platforms. Correcting the off-by-one error ensures proper configuration of output clocks. Signed-off-by: Shubhrajyoti Datta <shubhrajyoti.datta@amd.com> Signed-off-by: Stephen Boyd <sboyd@kernel.org>

2025-09-21clk: Use hashtable for global clk lookupsChen-Yu Tsai
A clk lookup using clk_core_lookup() is currently somewhat expensive since it has to walk the whole clk tree to find a match. This is extremely bad in the clk_core_init() function where it is used to look for clk name conflicts, which is always the worst case of walking the whole tree. Moreover, the number of clks checked increases as more clks are registered, causing each subsequent clk registration becoming slower. Add a hashtable for doing clk lookups to replace the tree walk method. On arm64 this increases kernel memory usage by 4 KB for the hashtable, and 16 bytes (2 pointers) for |struct hlist_node| in each clk. On a platform with around 800 clks, this reduces the time spent in clk_core_lookup() significantly: | PID 0 | kworker | | before | after | before | after | ------------------------------------------- avg | 203 us | 2.7 us | 123 us | 1.5 us | ------------------------------------------- min | 4.7 us | 2.3 us | 102 us | 0.9 us | ------------------------------------------- max | 867 us | 4.8 us | 237 us | 3.5 us | ------------------------------------------- culm | 109 ms | 1.5 ms | 21 ms | 0.3 ms | This in turn reduces the time spent in clk_hw_register(), and ultimately, boot time. On a different system with close to 700 clks, This reduces boot time by around 110 ms. While this doesn't seem like a lot, this helps in cases where minimizing boot time is important.

2025-09-21clk: bcm: rpi: Turn firmware clock on/off when preparing/unpreparingMaíra Canal
Currently, when we prepare or unprepare RPi's clocks, we don't actually enable/disable the firmware clock. This means that `clk_disable_unprepare()` doesn't actually change the clock state at all, nor does it lowers the clock rate. From the Mailbox Property Interface documentation [1], we can see that we should use `RPI_FIRMWARE_SET_CLOCK_STATE` to set the clock state off/on. Therefore, use `RPI_FIRMWARE_SET_CLOCK_STATE` to create a prepare and an unprepare hook for RPi's firmware clock. As now the clocks are actually turned off, some of them are now marked CLK_IS_CRITICAL, as those are required to be on during the whole system operation.

2025-09-21RDMA/rxe: Fix race in do_task() when drainingGui-Dong Han
When do_task() exhausts its iteration budget (!ret), it sets the state to TASK_STATE_IDLE to reschedule, without a secondary check on the current task->state. This can overwrite the TASK_STATE_DRAINING state set by a concurrent call to rxe_cleanup_task() or rxe_disable_task(). While state changes are protected by a spinlock, both rxe_cleanup_task() and rxe_disable_task() release the lock while waiting for the task to finish draining in the while(!is_done(task)) loop. The race occurs if do_task() hits its iteration limit and acquires the lock in this window. The cleanup logic may then proceed while the task incorrectly reschedules itself, leading to a potential use-after-free. This bug was introduced during the migration from tasklets to workqueues, where the special handling for the draining case was lost. Fix this by restoring the original pre-migration behavior. If the state is TASK_STATE_DRAINING when iterations are exhausted, set cont to 1 to force a new loop iteration. This allows the task to finish its work, so that a subsequent iteration can reach the switch statement and correctly transition the state to TASK_STATE_DRAINED, stopping the task as intended.
