No other driver does that. If you try to allocate more buffers then vb2
will automatically reduce the number of buffers anyway.

Also add sanity checks if the size in the fmt argument is going to be

never happen (the vb2 framework ensures that) and the code was wrong
anyway since *nbuffers should have been set to the minimum number of

[media] v4l2-subdev: Allow 32-bit compat ioctls

Add support for 32-bit ioctls with v4l-subdev device nodes.

Rather than keep adding new ioctls to the list in v4l2-compat-ioctl32.c, just check
if the ioctl is a non-private V4L2 ioctl and if so, call the conversion code.

We keep forgetting to add new ioctls, so this is a more robust solution.

In addition extend the subdev API with support for a compat32 function to
convert custom v4l-subdev ioctls.

Change 32bit NEC scancode format (used by Apple and TiVo remotes) to
encode the data with the correct bit order. Previously the raw bits were
used without being bit reversed, now each 16bit half is bit reversed
compared to before.

So for the raw NEC data:
  (LSB/First) 0xAAaaCCcc (MSB/Last)
(where traditionally AA=address, aa=~address, CC=command, cc=~command)

We now generate the scancodes:
  (MSB) 0x0000AACC (LSB) (normal NEC)
  (MSB) 0x00AAaaCC (LSB) (extended NEC, address check wrong)
  (MSB) 0xaaAAccCC (LSB) (32-bit NEC, command check wrong)

Note that the address byte order in 32-bit NEC scancodes is different to
that of the extended NEC scancodes. I chose this way as it maintains the
order of the bits in the address/command fields, and CC is clearly
intended to be the LSB of the command if the TiVo codes are anything to
go by so it makes sense for AA to also be the LSB.

The TiVo keymap is updated accordingly.

Since v3.12, specifically 153a60bb0fac ([media] rc: add feedback led
trigger for rc keypresses), an LED trigger is activated on IR keydown
whether or not a keypress is generated (i.e. even if there's no matching
keycode). However the repeat and keyup logic isn't used unless there is
a keypress, which results in non-keypress keydown events turning on the
LED and not turning it off again.

On the assumption that the intent was for the LED only to light up on
valid key presses (you probably don't want it lighting up for the wrong
remote control for example), move the led_trigger_event() call inside

So far we have been using HPA manual mode.
This way we had control of HPA which could be

Using a Mac Mini with mini-displayport to DVI-D converter as source

After experimenting with different configurations it was found that

be controlled by HPA prevented this error from occuring.

10 years agohpfs: optimize quad buffer loading
Mikulas Patocka [Tue, 28 Jan 2014 23:11:33 +0000 (00:11 +0100)]
hpfs: optimize quad buffer loading

HPFS needs to load 4 consecutive 512-byte sectors when accessing the
directory nodes or bitmaps.  We can't switch to 2048-byte block size
because files are allocated in the units of 512-byte sectors.

Previously, the driver would allocate a 2048-byte area using kmalloc,
copy the data from four buffers to this area and eventually copy them
back if they were modified.

In the current implementation of the buffer cache, buffers are allocated
in the pagecache.  That means that 4 consecutive 512-byte buffers are
stored in consecutive areas in the kernel address space.  So, we don't
need to allocate extra memory and copy the content of the buffers there.

This patch optimizes the code to avoid copying the buffers.  It checks
if the four buffers are stored in contiguous memory - if they are not,
it falls back to allocating a 2048-byte area and copying data there.

10 years agohpfs: remember free space
Mikulas Patocka [Tue, 28 Jan 2014 23:10:44 +0000 (00:10 +0100)]
hpfs: remember free space

Previously, hpfs scanned all bitmaps each time the user asked for free
space using statfs.  This patch changes it so that hpfs scans the
bitmaps only once, remembes the free space and on next invocation of
statfs it returns the value instantly.

New versions of wine are hammering on the statfs syscall very heavily,
making some games unplayable when they're stored on hpfs, with load
times in minutes.

This should be backported to the stable kernels because it fixes
user-visible problem (excessive level load times in wine).

10 years agoparisc: add flexible mmap memory layout support
Helge Deller [Fri, 31 Jan 2014 21:19:52 +0000 (22:19 +0100)]
parisc: add flexible mmap memory layout support

Add support for the flexible mmap memory layout (as described in
http://lwn.net/Articles/91829). This is especially very interesting on
parisc since we currently only support 32bit userspace (even with a
64bit Linux kernel).
