2023-08-22interconnect: Add debugfs test clientMike Tipton
It's often useful during test, debug, and development to issue path votes from shell. Add a debugfs client for this purpose. Example usage: cd /sys/kernel/debug/interconnect/test-client/ # Configure node endpoints for the path from CPU to DDR on # qcom/sm8550. echo chm_apps > src_node echo ebi > dst_node # Get path between src_node and dst_node. This is only # necessary after updating the node endpoints. echo 1 > get # Set desired BW to 1GBps avg and 2GBps peak. echo 1000000 > avg_bw echo 2000000 > peak_bw # Vote for avg_bw and peak_bw on the latest path from "get". # Voting for multiple paths is possible by repeating this # process for different nodes endpoints. echo 1 > commit Allowing userspace to directly enable and set bus rates can be dangerous So, following in the footsteps of the regmap [0] and clk [1] frameworks, keep these userspace controls compile-time disabled without Kconfig options to enable them. Enabling this will require code changes to define INTERCONNECT_ALLOW_WRITE_DEBUGFS.

Write support was present in the initial patch version, but dropped in v2 due to lack of users. We have a user now, so reintroduce it.

2023-08-22leds: trigger: netdev: rename 'hw_control' sysfs entry to 'offloaded'Marek Behún
Commit b655892ffd6d ("leds: trigger: netdev: expose hw_control status via sysfs") exposed to sysfs the flag that tells whether the LED trigger is offloaded to hardware, under the name "hw_control", since that is the name under which this setting is called in the code. Everywhere else in kernel when some work that is normally done in software can be made to be done by hardware instead, we use the word "offloading" to describe this, e.g. "LED blinking is offloaded to hardware". Normally renaming sysfs entries is a no-go because of backwards compatibility. But since this patch was not yet released in a stable kernel, I think it is still possible to rename it, if there is consensus.

2023-08-22HID: logitech-dj: Fix error handling in logi_dj_recv_switch_to_dj_mode()Nikita Zhandarovich
Presently, if a call to logi_dj_recv_send_report() fails, we do not learn about the error until after sending short HID_OUTPUT_REPORT with hid_hw_raw_request(). To handle this somewhat unlikely issue, return on error in logi_dj_recv_send_report() (minding ugly sleep workaround) and take into account the result of hid_hw_raw_request().

2023-08-22blk-mq: prealloc tags when increase tagset nr_hw_queuesChengming Zhou
Just like blk_mq_alloc_tag_set(), it's better to prepare all tags before using to map to queue ctxs in blk_mq_map_swqueue(), which now have to consider empty set->tags[]. The good point is that we can fallback easily if increasing nr_hw_queues fail, instead of just mapping to hctx[0] when fail in blk_mq_map_swqueue(). And the fallback path already has tags free & clean handling, so all is good.

2023-08-22blk-mq: fix tags leak when shrink nr_hw_queuesChengming Zhou
Although we don't need to realloc set->tags[] when shrink nr_hw_queues, we need to free them. Or these tags will be leaked. How to reproduce: 1. mount -t configfs configfs /mnt 2. modprobe null_blk nr_devices=0 submit_queues=8 3. mkdir /mnt/nullb/nullb0 4. echo 1 > /mnt/nullb/nullb0/power 5. echo 4 > /mnt/nullb/nullb0/submit_queues 6. rmdir /mnt/nullb/nullb0 In step 4, will alloc 9 tags (8 submit queues and 1 poll queue), then in step 5, new_nr_hw_queues = 5 (4 submit queues and 1 poll queue). At last in step 6, only these 5 tags are freed, the other 4 tags leaked.

Significant alterations have been made to the EDMA v3's register layout. Now, each channel possesses a separate address space, encapsulating all channel-related controls and statuses, including IRQs. There are changes in bit position definitions as well. However, the fundamental control flow remains analogous to the previous versions. EDMA v3 was utilized in imx8qm, imx93, and will be in forthcoming chips.

Relocates the tcd into the fsl_dma_chan structure. This adjustment reduces the need to reference back to fsl_edma_engine, paving the way for EDMA V3 support. Unified the edma_writel and edma_writew functions for accessing TCD (Transfer Control Descriptor) registers. A new macro is added that can automatically detect whether a 32-bit or 16-bit access should be used based on the structure field definition. This provide better support 64-bit TCD with future v5 version.
