Subject[PATCH] staging: Merge Crystal HD driver with linuxtv.org
From
Date
The in-kernel staging version and upstream diverged in Jan 2010,
whilst the in-kernel version has been kept up to date with kernel
changes, both have recieved some clean ups and bug fixes, upstream
has also added support for new cards, particularly BCM70015 which
is now a much more common device than the original BCM70012 and
is currently available for purchase.

In addition to the changes below, I've applied all the relevant
modifications applied to the in-kernel version to the new code
introduced from upstream, in particular the removal of typedefs and
unified header handling.

Quite a lot of the code churn relates to upstream commit
317dbd6dda65b4177627d6417b762c287cefa0e7 (crystalhd: nuke BCMLOG
macros, use std dev_foo ones), I considered stripping these changes
out and making them a separate patch but decided to stay as close as
possible to the state of the current linuxtv.org codebase.

Unfortunately, AFAIK, it's not possible to simply merge the upstream
git history since the upstream code isn't in a kernel tree structure,
and isn't even in a simple directory, but includes a script to
convert the external module into a staging tree driver which I used
to create a reference tree. I had to then manually merge both
versions and fix code conflicts.

It does now successfully detect and initialise a BCM70015 bought
last week from Amazon. It is currently untested on the original
BCM70012.

llseek: automatically add .llseek fop

All file_operations should get a .llseek operation so we can make
nonseekable_open the default for future file operations without a
.llseek pointer.

The three cases that we can automatically detect are no_llseek, seq_lseek
and default_llseek. For cases where we can we can automatically prove that
the file offset is always ignored, we use noop_llseek, which maintains
the current behavior of not returning an error from a seek.

New drivers should normally not use noop_llseek but instead use no_llseek
and call nonseekable_open at open time. Existing drivers can be converted
to do the same when the maintainer knows for certain that no user code
relies on calling seek on the device file.

The generated code is often incorrectly indented and right now contains
comments that clarify for each added line why a specific variant was
chosen. In the version that gets submitted upstream, the comments will
be gone and I will manually fix the indentation, because there does not
seem to be a way to do that using coccinelle.

Some amount of new code is currently sitting in linux-next that should get
the same modifications, which I will do at the end of the merge window.

Many thanks to Julia Lawall for helping me learn to write a semantic
patch that does all this.

// - use seq_lseek for sequential files

// - use noop_llseek if we know we don't access f_pos,
// but we still want to allow users to call lseek

lib: fix DtsFlushInput segfault

PESConvParams buffer ownership is wacky. DtsReleasePESConverter is
called when device is closed, DtsSetPESConverter (and
DtsInitPESConverter ) in DtsSetInputFormat before DtsOpenDecoder.

But you call DtsFlushInput(m_device, 2), "Flushes all the decoder
buffers, input, decoded and to be decoded."

then decoder is closed/opened and the close nukes PESConvParams buffers
and the next time one feeds DtsProcInput, you segfault.

You could keep a copy of what is passed into DtsSetInputFormat and reset
on internal/open close of decoder but it's easier to just not touch
PESConvParams buffers, they will get deleted when device is closed or
resized as needed.

crystalhd: add locking around hw accesses

Fixed issue of holding HW lock and sleeping in kernel when probing for
picture numbers. Fixed parsing of the Mode field so we can release DMA
buffers correctly. Correctly working with Adobe FP for both 70012 and
70015. Elimiated HW pause for 70012 since it is borked. Added SW pause
from apps side. Currently only for FP and GST. Need to
fix for other apps.

crystalhd: Fix for big-endian systems

The original CrystalHD driver assumes a little endian bitfield host.

This patch adds support for big-endian bitfield hosts.

It was tested by verifying the values of all hardware register accesses
on a big-endian host were equal to a little-endian host.

The use of bitfields is discouraged for hardware access, so this needs
to be rewritten to use macro definitions at some point.

Compile fails w/a message about converting to a pointer from an integer

a cast to uintptr_t first, which gets the size right regardless of if we
are on 32-bit or 64-bit. Not fully tested to be sure its also working as
expected on 64-bit, but at least it builds...

crystalhd: add debug printk of register accesses

The CrystalHD device driver assumes a little endian host. In order to
verify future work on endianess-independence, this patch adds
printk's to track the register access to the device.

This helps verify bitfield endianess correctness as well as any
hard-coded assumptions in the driver code.

lib: fix instances of calling printf with int cast to char*

In DtsProcInput(), there are calls to DebugLog_Trace(_tl, fmt, args...)
with first argument being a TEXT("message: %x"), and second (char*)sts.

TEXT is defined to nothingness, so the actual message is passed via the
unused _tl argument, and sts (status integer) is cast to char* (!) and
used as the format string.

Fix the DebugLog_Trace() calls to pass the proper arguments and remove
the now unused TEXT define.
