[media] v4l: vb2: Add fatal error condition flag

When a fatal error occurs that render the device unusable, the only
options for a driver to signal the error condition to userspace is to
set the V4L2_BUF_FLAG_ERROR flag when dequeuing buffers and to return an
error from the buffer prepare handler when queuing buffers.

The buffer error flag indicates a transient error and can't be used by
applications to detect fatal errors. Returning an error from vb2_qbuf()
is thus the only real indication that a fatal error occurred. However,
this is difficult to handle for multithreaded applications that requeue
buffers from a thread other than the control thread. In particular the
poll() call in the control thread will not notify userspace of the
error.

This patch adds an explicit mechanism to report fatal errors to
userspace. Drivers can call the vb2_queue_error() function to signal a
fatal error. From this moment on, buffer preparation will return -EIO to
userspace, and vb2_poll() will set the POLLERR flag and return
immediately. The error flag is cleared when cancelling the queue, either
at stream off time (through vb2_streamoff) or when releasing the queue
with vb2_queue_release().

the poll() function succeeds, but sets the POLLERR flag in the revents

10 years ago[media] v4l2-ctrls: increase internal min/max/step/def to 64 bit

[media] v4l2-ctrls: increase internal min/max/step/def to 64 bit

While VIDIOC_QUERYCTRL is limited to 32 bit min/max/step/def values
for controls, the upcoming VIDIOC_QUERY_EXT_CTRL isn't. So increase
the internal representation to 64 bits in preparation.

Because of these changes the msi3101 driver has been modified slightly
to fix a formatting issue (%d becomes %lld), vivi had to be modified
as well to cope with the new 64-bit min/max values and the PIXEL_RATE
control in a few sensor drivers required proper min/max/def values.

clk: spear3xx: Set proper clock parent of uart1/2

The uarts only work when the parent is ras_ahb_clk. The stale 3.5
based ST tree does this in the board file.

Add it to the clk init function. Not pretty, but the mess there is
amazing anyway.

10 years agoparisc: fix fanotify_mark() syscall on 32bit compat kernel
Helge Deller [Thu, 10 Jul 2014 16:07:17 +0000 (18:07 +0200)]
parisc: fix fanotify_mark() syscall on 32bit compat kernel

On parisc we can not use the existing compat implementation for fanotify_mark()
because for the 64bit mask parameter the higher and lower 32bits are ordered
differently than what the compat function expects from big endian
architectures.

Specifically:
It finally turned out, that on hppa we end up with different assignments
of parameters to kernel arguments depending on if we call the glibc
wrapper function
 int fanotify_mark (int __fanotify_fd, unsigned int __flags,
                    uint64_t __mask, int __dfd, const char *__pathname);
or directly calling the syscall manually
 syscall(__NR_fanotify_mark, ...)

Reason is, that the syscall() function is implemented as C-function and
because we now have the sysno as first parameter in front of the other
parameters the compiler will unexpectedly add an empty paramenter in
front of the u64 value to ensure the correct calling alignment for 64bit
values.
This means, on hppa you can't simply use syscall() to call the kernel
fanotify_mark() function directly, but you have to use the glibc
function instead.

This patch fixes the kernel in the hppa-arch specifc coding to adjust
the parameters in a way as if userspace calls the glibc wrapper function
fanotify_mark().
