2021-10-18nvme: wire up completion batching for the IRQ pathJens Axboe1-1/+5
Trivial to do now, just need our own io_comp_batch on the stack and pass that in to the usual command completion handling. I pondered making this dependent on how many entries we had to process, but even for a single entry there's no discernable difference in performance or latency. Running a sync workload over io_uring: t/io_uring -b512 -d1 -s1 -c1 -p0 -F1 -B1 -n2 /dev/nvme1n1 /dev/nvme2n1 yields the below performance before the patch: IOPS=254820, BW=124MiB/s, IOS/call=1/1, inflight=(1 1) IOPS=251174, BW=122MiB/s, IOS/call=1/1, inflight=(1 1) IOPS=250806, BW=122MiB/s, IOS/call=1/1, inflight=(1 1) and the following after: IOPS=255972, BW=124MiB/s, IOS/call=1/1, inflight=(1 1) IOPS=251920, BW=123MiB/s, IOS/call=1/1, inflight=(1 1) IOPS=251794, BW=122MiB/s, IOS/call=1/1, inflight=(1 1) which definitely isn't slower, about the same if you factor in a bit of variance. For peak performance workloads, benchmarking shows a 2% improvement. Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2021-10-18nvme: add support for batched completion of polled IOJens Axboe3-12/+51
Take advantage of struct io_comp_batch, if passed in to the nvme poll handler. If it's set, rather than complete each request individually inline, store them in the io_comp_batch list. We only do so for requests that will complete successfully, anything else will be completed inline as before. Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2021-10-18block: add a struct io_comp_batch argument to fops->iopoll()Jens Axboe5-6/+6
struct io_comp_batch contains a list head and a completion handler, which will allow completions to more effciently completed batches of IO. For now, no functional changes in this patch, we just define the io_comp_batch structure and add the argument to the file_operations iopoll handler.

2021-10-18block: switch polling to be bio basedChristoph Hellwig18-88/+55
Replace the blk_poll interface that requires the caller to keep a queue and cookie from the submissions with polling based on the bio. Polling for the bio itself leads to a few advantages: - the cookie construction can made entirely private in blk-mq.c - the caller does not need to remember the request_queue and cookie separately and thus sidesteps their lifetime issues - keeping the device and the cookie inside the bio allows to trivially support polling BIOs remapping by stacking drivers - a lot of code to propagate the cookie back up the submission path can be removed entirely.

2021-10-18block: Rename BLKDEV_MAX_RQ -> BLKDEV_DEFAULT_RQJohn Garry1-1/+1
It is a bit confusing that there is BLKDEV_MAX_RQ and MAX_SCHED_RQ, as the name BLKDEV_MAX_RQ would imply the max requests always, which it is not. Rename to BLKDEV_MAX_RQ to BLKDEV_DEFAULT_RQ, matching its usage - that being the default number of requests assigned when allocating a request queue.

2021-10-16Input: touchscreen - avoid bitwise vs logical OR warningNathan Chancellor1-21/+21
A new warning in clang points out a few places in this driver where a bitwise OR is being used with boolean types: drivers/input/touchscreen.c:81:17: warning: use of bitwise '|' with boolean operands [-Wbitwise-instead-of-logical] data_present = touchscreen_get_prop_u32(dev, "touchscreen-min-x", ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This use of a bitwise OR is intentional, as bitwise operations do not short circuit, which allows all the calls to touchscreen_get_prop_u32() to happen so that the last parameter is initialized while coalescing the results of the calls to make a decision after they are all evaluated. To make this clearer to the compiler, use the '|=' operator to assign the result of each touchscreen_get_prop_u32() call to data_present, which keeps the meaning of the code the same but makes it obvious that every one of these calls is expected to happen.

2021-10-16Input: snvs_pwrkey - add clk handlingUwe Kleine-König1-0/+29
On i.MX7S and i.MX8M* (but not i.MX6*) the pwrkey device has an associated clock. Accessing the registers requires that this clock is enabled. Binding the driver on at least i.MX7S and i.MX8MP while not having the clock enabled results in a complete hang of the machine. (This usually only happens if snvs_pwrkey is built as a module and the rtc-snvs driver isn't already bound because at bootup the required clk is on and only gets disabled when the clk framework disables unused clks late during boot.) This completes the fix in commit 135be16d3505 ("ARM: dts: imx7s: add snvs clock to pwrkey").
