Add support for YWRAP scrolling by shuffling pages around in DMM instead of sw blits. Note that fbcon only utilizes this mode if the y resolution is divided evenly by the font height. So, for example, a 1920x1080 display using a 16 pixel tall font will not utilize this, but a 1280x1024 display would. Signed-off-by:

The PCM subsystem in the Line6 driver is mainly used for PCM playback and capture by ALSA, but also has other tasks, most notably providing a low-latency software monitor for devices which don't support hardware monitoring (e.g., the TonePort series). This patch makes ALSA "play nicely" with the other components, i.e., prevents it from resetting the isochronous USB transfer while other PCM tasks (software monitoring) are running. Signed-off-by:

The .trigger() pcm callbacks are not allowed to block and cannot wait until urbs have completed. We need to ensure that stopping, preparing, and then restarting a stream always works. Currently the driver will sometimes return -EBUSY when restarting the stream because urbs have not completed yet. This can be triggered by jackd from userspace. The solution is to wait on urbs in the .prepare() pcm callback since blocking is allowed in that callback. This guarantees that all urbs are quiesced and ready to be submitted when the start trigger callback is invoked. Signed-off-by:

The line6 driver checks struct field addresses for NULL where it does not make sense to do so. The struct has already been checked for NULL and there is no value in checking the first field's address too. Suggested-by:

Playback urbs use the index_out counter to decide which part of the playback buffer to use. Since the urb already has a unique index in range [0, LINE6_ISO_BUFFERS) there is no need to keep a separate counter. Use the urb index instead. This also eliminates the possibility of two urbs using the same playback buffer space if they ever complete out-of-order for some reason. Signed-off-by:

Stefan Hajnoczi authored
The playback urb transfer buffer calculation does not factor in LINE6_ISO_PACKETS. Buffer memory is organized like this in the driver: Buffer 0 Buffer 1 ... [Packet 0, Packet 1, ...][Packet 0, Packet 1, ...][Packet 0, ...] However, we're lucky that LINE6_ISO_PACKETS is currently defined as 1 so this patch does not change any behavior. It's still worth including this fix in case the LINE6_ISO_PACKETS value is changed in the future. Signed-off-by:

The ring buffer is only used to pass meta data for outbound packets. The actual payload is accessed by DMA from the host. So the stop/wake queue mechanism based on counting and comparing number of pages sent v.s. number of pages in the ring buffer is wrong. Also, there is a race condition in the stop/wake queue calls, which can stop xmit queue forever. The new stop/wake queue mechanism is based on the actual bytes used by outbound packets in the ring buffer. The check for number of outstanding sends after stop queue prevents the race condition that can cause wake queue happening earlier than stop queue. Signed-off-by:

Since commit a25cac51 ("proc: Consider NO_HZ when printing idle and iowait times") we are reporting idle/io_wait time also while a CPU is tickless. We rely on get_{idle,iowait}_time functions to retrieve proper data. These functions, however, use usecs_to_cputime to translate micro seconds time to cputime64_t. This is just an alias to usecs_to_jiffies which reduces the data type from u64 to unsigned int and also checks whether the given parameter overflows jiffies_to_usecs(MAX_JIFFY_OFFSET) and returns MAX_JIFFY_OFFSET in that case. When we overflow depends on CONFIG_HZ but especially for CONFIG_HZ_300 it is quite low (1431649781) so we are getting MAX_JIFFY_OFFSET for >3000s! until we overflow unsigned int. Just for reference CONFIG_HZ_100 has an overflow window around 20s, CONFIG_HZ_250 ~8s and CONFIG_HZ_1000 ~2s. This results in a bug when people saw [h]top going mad reporting 100% CPU usage even though there was basically no CPU load. The reason was simply that /proc/stat stopped reporting idle/io_wait changes (and reported MAX_JIFFY_OFFSET) and so the only change happening was for user system time. Let's use nsecs_to_jiffies64 instead which doesn't reduce the precision to 32b type and it is much more appropriate for cumulative time values (unlike usecs_to_jiffies which intended for timeout calculations).

Commit f5252e00 ("mm: avoid null pointer access in vm_struct via /proc/vmallocinfo") adds newly allocated vm_structs to the vmlist after it is fully initialised. Unfortunately, it did not check that __vmalloc_area_node() successfully populated the area. In the event of allocation failure, the vmalloc area is freed but the pointer to freed memory is inserted into the vmlist leading to a a crash later in get_vmalloc_info(). This patch adds a check for ____vmalloc_area_node() failure within __vmalloc_node_range. It does not use "goto fail" as in the previous error path as a warning was already displayed by __vmalloc_area_node() before it called vfree in its failure path. Credit goes to Luciano Chavez for doing all the real work of identifying exactly where the problem was. Signed-off-by:
