2024-12-19perf: imx9_perf: Introduce AXI filter version to refactor the driver and ↵Xu Yang
better extension The imx93 is the first supported DDR PMU that supports read transaction, write transaction and read beats events which corresponding respecitively to counter 2, 3 and 4. However, transaction-based AXI match has low accuracy when get total bits compared to beats-based. And imx93 doesn't assign AXI_ID to each master. So axi filter is not used widely on imx93. This could be regards as AXI filter version 1. To improve the AXI filter capability, imx95 supports 1 read beats and 3 write beats event which corresponding respecitively to counter 2-5. imx95 also detailed AXI_ID allocation so that most of the master could be count individually. This could be regards as AXI filter version 2. This will introduce AXI filter version to refactor the driver and support better extension, such as coming imx943. This is also a potential fix on imx91 when configure axi filter.

2024-12-19perf/arm-cmn: Permit more exhaustive groupsRobin Murphy
The group validation logic still somewhat assumes the original CMN-600 case of events counting globally, such that if one tries to group 9 events where the first 8 target a single DTC domain, the 9th will be rejected because *a* DTC domain is full, even though it might only target other non-overlapping domains and thus still be schedulable. Improve matters by only counting the DTCs that the new event actually needs (as arm_cmn_val_add_event() was already clever enough to do).

2024-12-18net: renesas: rswitch: align mdio C45 operations with datasheetNikita Yushchenko
Per rswitch datasheet, software can know that mdio operation completed either by polling MPSM.PSME bit, or via interrupt. Instead, the driver currently polls for interrupt status bit. Although this still provides correct result, it requires additional register operations to clean the interrupt status bits, and generally looks wrong. Fix it to poll MPSM.PSME bit, as the datasheet suggests.

Setting backing device is done before ZRAM initialization. If we set the backing device, then remove the ZRAM module without initializing the device, the backing device reference will be leaked and the device will be hold forever. Fix this by always reset the ZRAM fully on rmmod or reset store.

2024-12-18zram: refuse to use zero sized block device as backing deviceKairui Song
Patch series "zram: fix backing device setup issue", v2. This series fixes two bugs of backing device setting: - ZRAM should reject using a zero sized (or the uninitialized ZRAM device itself) as the backing device. - Fix backing device leaking when removing a uninitialized ZRAM device. This patch (of 2): Setting a zero sized block device as backing device is pointless, and one can easily create a recursive loop by setting the uninitialized ZRAM device itself as its own backing device by (zram0 is uninitialized): echo /dev/zram0 > /sys/block/zram0/backing_dev It's definitely a wrong config, and the module will pin itself, kernel should refuse doing so in the first place. By refusing to use zero sized device we avoided misuse cases including this one above.
