[ Upstream commit 8820a4cf ] At a commit 9dc5d31c ("ALSA: firewire-digi00x: handle MIDI messages in isochronous packets"), a functionality to handle MIDI messages on isochronous packet was supported. But this includes some of my misunderstanding. This commit is to fix them. For digi00x series, first data channel of data blocks in rx/tx packet includes MIDI messages. The data channel has 0x80 in 8 bit of its MSB, however it's against IEC 61883-6. Unique data format is applied: - Upper 4 bits of LSB represent port number. - 0x0: port 1. - 0x2: port 2. - 0xe: console port. - Lower 4 bits of LSB represent the number of included MIDI message bytes; 0x0/0x1/0x2. - Two bytes of middle of this data channel have MIDI bytes. Especially, MIDI messages from/to console surface are also transferred by isochronous packets, as well as physical MIDI ports.

[ Upstream commit 13e005f9 ] Digi00x series includes two types of unit; rack and console. As long as reading information on config rom of Digi 002 console, 'MODEL_ID' field has a different value from the one on Digi 002 rack. We've already got a test report from users with Digi 003 rack. We can assume that console type and rack type has different value in the field. This commit adds a device entry for console type. For following commits, this commit also adds a member to 'struct snd_digi00x' to identify console type. $ cd linux-firewire-utils/src $ python2 ./crpp < /sys/bus/firewire/devices/fw1/config_rom ROM header and bus information block ----------------------------------------------------------------- 400 0404f9d0 bus_info_length 4, crc_length 4, crc 63952 404 31333934 bus_name "1394" 408 60647002 irmc 0, cmc 1, isc 1, bmc 0, cyc_clk_acc 100, max_rec 7 (256) 40c 00a07e00 company_id 00a07e | 410 00a30000 device_id 0000a30000 | EUI-64 00a07e0000a30000 root directory ----------------------------------------------------------------- 414 00058a39 directory_length 5, crc 35385 418 0c0043a0 node capabilities 41c 04000001 hardware version 420 0300a07e vendor 424 81000007 --> descriptor leaf at 440 428 d1000001 --> unit directory at 42c unit directory at 42c ----------------------------------------------------------------- 42c 00046674 directory_length 4, crc 26228 430 120000a3 specifier id 434 13000001 version 438 17000001 model 43c 81000007 --> descriptor leaf at 458 descriptor leaf at 440 ----------------------------------------------------------------- 440 00055913 leaf_length 5, crc 22803 444 000050f2 descriptor_type 00, specifier_ID 50f2 448 80000000 44c 44696769 450 64657369 454 676e0000 descriptor leaf at 458 ----------------------------------------------------------------- 458 0004a6fd leaf_length 4, crc 42749 45c 00000000 textual descriptor 460 00000000 minimal ASCII 464 44696769 "Digi" 468 20303032 " 002" Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Sasha Levin <alexander.levin@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

[ Upstream commit 7b87463e ] The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.

[ Upstream commit 71b0576b ] Currently canceling of delayed work that flushes old data using cancel_old_flush() does not prevent work from being requeued. Thus in theory new work can be queued after cancel_old_flush() from reiserfs_freeze() has run. This will become larger problem once flush_old_commits() can requeue the work itself. Fix the problem by recording in sbi->work_queue that flushing work is canceled and should not be requeued.

[ Upstream commit 257ab443 ] Some console drivers code calls console_conditional_schedule() that looks at @console_may_schedule. The value must be cleared when the drivers are called from console_unlock() with interrupts disabled. But rescheduling is fine when the same code is called, for example, from tty operations where the console semaphore is taken via console_lock(). This is why @console_may_schedule is cleared before calling console drivers. The original value is stored to decide if we could sleep between lines. Now, @console_may_schedule is not cleared when we call console_trylock() and jump back to the "again" goto label. This has become a problem, since the commit 6b97a20d ("printk: set may_schedule for some of console_trylock() callers"). @console_may_schedule might get enabled now. There is also the opposite problem. console_lock() can be called only from preemptive context. It can always enable scheduling in the console code. But console_trylock() is not able to detect it when CONFIG_PREEMPT_COUNT is disabled. Therefore we should use the original @console_may_schedule value after re-acquiring the console semaphore in console_unlock(). This patch solves both problems by moving the "again" goto label. Alternative solution was to clear and restore the value around call_console_drivers(). Then console_conditional_schedule() could be used also inside console_unlock(). But there was a potential race with console_flush_on_panic() as reported by Sergey Senozhatsky. That function should be called only where there is only one CPU and with interrupts disabled. But better be on the safe side because stopping CPUs might fail.

[ Upstream commit e0aad5b4 ] rt_mutex_waiter::prio is a copy of task_struct::prio which is updated during the PI chain walk, such that the PI chain order isn't messed up by (asynchronous) task state updates. Currently rt_mutex_waiter_less() uses task state for deadline tasks; this is broken, since the task state can, as said above, change asynchronously, causing the RB tree order to change without actual tree update -> FAIL. Fix this by also copying the deadline into the rt_mutex_waiter state and updating it along with its prio field. Ideally we would also force PI chain updates whenever DL tasks update their deadline parameter, but for first approximation this is less broken than it was.

[ Upstream commit a7a9dcd8 ] Early on in do_page_fault() we call store_updates_sp(), regardless of the type of exception. For an instruction miss this doesn't make sense, because we only use this information to detect if a data miss is the result of a stack expansion instruction or not. Worse still, it results in a data miss within every userspace instruction miss handler, because we try and load the very instruction we are about to install a pte for! A simple exec microbenchmark runs 6% faster on POWER8 with this fix: #include <stdlib.h> #include <stdio.h> #include <unistd.h> int main(int argc, char *argv[]) { unsigned long left = atol(argv[1]); char leftstr[16]; if (left-- == 0) return 0; sprintf(leftstr, "%ld", left); execlp(argv[0], argv[0], leftstr, NULL); perror("exec failed\n"); return 0; } Pass the number of iterations on the command line (eg 10000) and time how long it takes to execute.

[ Upstream commit 142c6594 ] Some device drivers reset their stats at down/up events, possibly fooling bonding stats, since they operate with relative deltas. It is nearly not possible to fix drivers, since some of them compute the tx/rx counters based on per rx/tx queue stats, and the queues can be reconfigured (ethtool -L) between the down/up sequence. Lets avoid accumulating 'negative' values that render bonding stats useless. It is better to lose small deltas, assuming the bonding stats are fetched at a reasonable frequency.

[ Upstream commit fd2b2975 ] Which may happen when we start a tracing session and a thread is waiting for something like "poll" to return, in which case we better print "?" both for the syscall entry timestamp and for the duration. E.g.: Tracing existing mutt session: # perf trace -p `pidof mutt` ? ( ? ): mutt/17135 ... [continued]: poll()) = 1 0.027 ( 0.013 ms): mutt/17135 read(buf: 0x7ffcb3c42cef, count: 1) = 1 0.047 ( 0.008 ms): mutt/17135 poll(ufds: 0x7ffcb3c42c50, nfds: 1, timeout_msecs: 1000) = 1 0.059 ( 0.008 ms): mutt/17135 read(buf: 0x7ffcb3c42cef, count: 1) = 1 <SNIP> Before it would print a large number because we'd do: ttrace->entry_time - trace->base_time And entry_time would be 0, while base_time would be the timestamp for the first event 'perf trace' reads, oops.

[ Upstream commit fd086045 ] Commit 26988efe ("regulator: core: Allow to get voltage count and list from parent") introduces the propagation of the parent voltage count and list for regulators that don't provide this information themselves. The goal is to support simple switch regulators, however as a side effect normal continuous regulators can leak details of their supplies and provide consumers with inconsistent information. Limit the propagation of the voltage count and list to switch regulators.

[ Upstream commit 06cceedc ] cgroup could be throttled to a limit but when all cgroups cross high limit, queue enters a higher state and so the group should be throttled to a higher limit. It's possible the cgroup is sleeping because of throttle and other cgroups don't dispatch IO any more. In this case, nobody can trigger current downgrade/upgrade logic. To fix this issue, we could either set up a timer to wakeup the cgroup if other cgroups are idle or make sure this cgroup doesn't sleep too long. Setting up a timer means we must change the timer very frequently. This patch chooses the latter. Making cgroup sleep time not too big wouldn't change cgroup bps/iops, but could make it wakeup more frequently, which isn't a big issue because throtl_slice * 8 is already quite big.

[ Upstream commit c4adfc82 ] bond_update_speed_duplex() retrieves speed and duplex settings. There is a possibility of failure in retrieving these values but caller has to assume it's always successful. This leads to having inconsistent slave link settings. If these (speed, duplex) values cannot be retrieved, then keeping the link UP causes problems. The updated bond_update_speed_duplex() returns 0 on success if it retrieves sane values for speed and duplex. On failure it returns 1 and marks the link down.
