Takashi Iwai authored
Fix the key value generation for get/set amp verbs. The upper bits of the parameter have to be combined with the verb value to be unique for each direction/index of amp access. This fixes the resume problem on some hardwares like Macbook after the channel mode is changed.

It turns out that 'smp_call_function_many()' doesn't work at all like 'smp_call_function_single()', and my change to Andrew's patch to use it rather than a loop over all CPU's acpi-cpufreq doesn't work. My bad. 'smp_call_function_many()' has two "features" (aka "documented bugs"): (a) it needs to be called with preemption disabled, because it uses smp_processor_id() without guarding the CPU lookup with 'get_cpu()' and 'put_cpu()' like the 'single' variant does. (b) even if the current CPU is part of the CPU mask, it won't do the call on that CPU. Still, we're better off trying to use 'smp_call_function_many()' than looping over CPU's, since it at least in theory allows us to use a broadcast IPI and do it all in parallel. So let's just work around the silly semantic bugs in that function.

If we have processes that are working in close proximity to each other on disk, we don't want to idle wait. Instead allow the close process to issue a request, getting better aggregate bandwidth. The anticipatory scheduler has similar checks, noop and deadline do not need it since they don't care about process <-> io mappings. The code for CFQ is a little more involved though, since we split request queues into per-process contexts. This fixes a performance problem with eg dump(8), since it uses several processes in some silly attempt to speed IO up. Even if dump(8) isn't really a valid case (it should be fixed by using CLONE_IO), there are other cases where we see close processes and where idling ends up hurting performance. Credit goes to Jeff Moyer <jmoyer@redhat.com> for writing the initial implementation. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

Jens Axboe authored
We only kick the dispatch for an idling queue, if we think it's a (somewhat) fully merged request. Also allow a kick if we have other busy queues in the system, since we don't want to risk waiting for a potential merge in that case. It's better to get some work done and proceed.

brd is missing a flush_dcache_page. On 2nd thoughts, perhaps it is the pagecache's responsibility to flush user virtual aliases (the driver of course should flush kernel virtual mappings)... but anyway, there already exists cache flushing for one direction of transfer, so we should add the other.

Miklos Szeredi authored
There are lots of sequences like this, especially in splice code: if (pipe->inode) mutex_lock(&pipe->inode->i_mutex); /* do something */ if (pipe->inode) mutex_unlock(&pipe->inode->i_mutex); so introduce helpers which do the conditional locking and unlocking. Also replace the inode_double_lock() call with a pipe_double_lock() helper to avoid spreading the use of this functionality beyond the pipe code. This patch is just a cleanup, and should cause no behavioral changes. Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

Remove the now unused generic_file_splice_write_nolock() function. It's conceptually broken anyway, because splice may need to wait for pipe events so holding locks across the whole operation is wrong.

Miklos Szeredi authored
Split up __splice_from_pipe() into four helper functions: splice_from_pipe_begin() splice_from_pipe_next() splice_from_pipe_feed() splice_from_pipe_end() splice_from_pipe_next() will wait (if necessary) for more buffers to be added to the pipe. splice_from_pipe_feed() will feed the buffers to the supplied actor and return when there's no more data available (or if all of the requested data has been copied). This is necessary so that implementations can do locking around the non-waiting splice_from_pipe_feed(). This patch should not cause any change in behavior.
