This is an RFC patch to explore the solution to a problem we have
in the CoreSight ETM/ETE PMU.
CoreSight ETM trace allows instruction level tracing of Arm CPUs.
The ETM generates the CPU excecution trace and pumps it into CoreSight
AMBA Trace Bus and is collected by a different CoreSight componen
CoreSight PMU supports aux-buffer for the ETM tracing. The trace
generated by the ETM (associated with individual CPUs, like Intel PT)
is captured by a separate IP (CoreSight TMC-ETR/ETF until now).
The TMC-ETR applies formatting of the raw ETM trace data, as it
can collect traces from multiple ET

Currently the ! operator is incorrectly being used to flip bits on

The scan_elements attributes are solely located inside
'industrialio-buffer-sysfs.c'. In order to support more than one buffer per
IIO device, we need to expand scan_elements attributes directly to IIO
buffer object, and not the IIO device.
This also requires that a new 'iio_buffer_attr' type be a
In order to keep backwards compatibility with the current chardev
mechanism, and in order to add support for multiple buffers per IIO device,
we need to pass both the IIO device & IIO buffer to the chardev.
This is particularly needed for the iio_buffer_read_outer() function, where
we need to pass
With this change, calling iio_device_attach_buffer() will actually attach
more buffers.
Right now this doesn't do any validation of whether a buffer is attached
twice; maybe that can be added later (if needed). Attaching a buffer more
than once should yield noticeably bad results.
The first buffer
With this change, an ioctl() call is added to open a character device for a
buffer.
The ioctl() will return a 0 FD for the first buffer, as that FD for buffer0
is the same FD as the one used for this ioctl().
For any other extra buffer, this ioctl() will return an anon inode FD that
would access a

I can read the logs from QNX side from the memory reserved before on the

Now that the iio_buffer_set_attrs() has been removed, we can be sure that
no accidents can happen with drivers that try to provide extra buffer
attributes that expand to iio_dev objects.
So, we can convert all remaining buffer attributes to expand to iio_buffer
objects.
These will look a bit weird
For now "reserve=" is limitied to 32bit,not available on 64bit

For the buffer attributes that are present inside the IIO core buffer logic
we can re-route them to expand the attribute into iio_buffer objects.

A second CHARLCD config symbol was added instead of moving the existing
one. Fix this by removing the old one.

This is a combination of Christoph's work to refactor
generic_file_buffered_read() and some of my large-page support
which was disrupted by Kent's refactoring of generic_file_buffered_read.

Increasing the batch size runs into diminishing returns. It's probably
better to make, eg, three calls to filemap_get_pages() than it is to
call into kmalloc().

The recent split of generic_file_buffered_read() created some very
long function names which are hard to distinguish from each other.
Rename as follows:
generic_file_buffered_read_readpage -> filemap_read_page
generic_file_buffered_read_pagenotuptodate -> filemap_update_page

Add filemap_get_read_batch() which returns the head pages which represent
a contiguous array of bytes in the file. It also stops when encountering
a page marked as Readahead or !Uptodate (but does return that page)
so it can be handled appropriately by filemap_get_pages(). That lets
us remove the
This is prep work for the next patch, but I think at least one of the
current callers would prefer a killable sleep to an uninterruptible one.

For page splitting to succeed, the thread asking to split the
page has to be the only one with a reference to the page. Calling
wait_on_page_locked() while holding a reference to the page will
effectively prevent this from happening with sufficient threads waiting
on the same page. Use put_and_wa

The previous patch removed wait_on_page_locked_async(), so inline
__wait_on_page_locked_async into __lock_page_async().

The readpage operation can block in many (most?) filesystems, so we
should punt to a work queue instead of calling it. This was the last
caller of lock_page_for_iocb(), so remove it.

By moving the iocb flag checks to the caller, we can pass the
file and the page index instead of the iocb. It never needed the iter.
By passing the pagevec, we can return an errno (or AOP_TRUNCATED_PAGE)
instead of an ERR_PTR.

Use AOP_TRUNCATED_PAGE to indicate that no error occurred, but the

to the page will have been removed; if we hit any other error, the
