Hello
The zoran driver was removed in 5.3
The main reason of the removing was lack of motivation to convert it to
VB2
Since I need it, I worked on bringing it back.
So the plan to achieve it was:
- clean up the coding style.
- convert old usage/API
- clean unused code
- convert to VB2
I have tried to split a bit the VB2 patch (by adding/removing code in
another patch), but the result is unfortunately still a big patch.
The result of this serie is a working zoran driver.
Furthermore it is now compliant to v4l-compliance.
In the process some old (useless) feature (fbuf, overlay) was removed
for simplifying maintenance.
The zoran hardware support MJPEG decompression, but this feature is
temporarily disabled by this serie.
But basically, this feature was unusable, since the only tool which
permitted to use it was a mplayer option.
But this mplayer option no longer compile (probably since a long time)
and is such a hack (a copy of some private ffmpeg structure) that it is
unfixable.
Happily, when I started to work on zoran, a patch was posted on ffmpeg
ML which permit it to output non-raw video stream (and so MJPEG for
zoran case).
But the zoran hw does not like some part of JPEG header it receives, so
a filter need to be written.
Anyway, this disabling is not a regression, since this feature was not
usable since a long time.
Since the driver was in staging, I targeted staging, but probably the
driver is in a sufficient good shape to target media and bypass staging.
This driver is tested on a DC10+ (on x86). Tests on different hardware
are welcome.
I would like to thanks all people that helped me to achieve this (mostly
#v4l)
Regards
PS: this serie is resent a bit soon since linux-media didnt get some patch
and cover letter
Changes since RFC1
- removed fallthough patch
- removed unsplit lines patch
- fixed line size in "Use DMA coherent for stat_com" patch

- * Allocate the MJPEG grab buffers.
- *
- * If a Natoma chipset is present and this is a revision 1 zr36057,
- * each MJPEG buffer needs to be physically contiguous.
- * (RJ: This statement is from Dave Perks' original driver,
- * I could never check it because I have a zr36067)
- *
- * RJ: The contents grab buffers needs never be accessed in the driver.
- * Therefore there is no need to allocate them with vmalloc in order
- * to get a contiguous virtual memory space.
- * I don't understand why many other drivers first allocate them with
- * vmalloc (which uses internally also get_zeroed_page, but delivers you
- * virtual addresses) and then again have to make a lot of efforts
- * to get the physical address.
- *
- * Ben Capper:
- * On big-endian architectures (such as ppc) some extra steps
- * are needed. When reading and writing to the stat_com array
- * and fragment buffers, the device expects to see little-
- * endian values. The use of cpu_to_le32() and le32_to_cpu()
- * in this function (and one or two others in zoran_device.c)
- * ensure that these values are always stored in little-endian
- * form, regardless of architecture. The zr36057 does Very Bad
- * Things on big endian architectures if the stat_com array
- * and fragment buffers are not little-endian.

+
+ The original way of sending video was via mplayer vo_zr/vo_zr2, but it does not compile

+- fix the v4l compliance "TRY_FMT cannot handle an invalid pixelformat"
+- Filter JPEG data to made output work

IMO: this change does little for readability or makes it worse.
Can you please keep to 80 columns where it's already 80 columns?

Thank you very much for your hard work!
I've just posted a PR for this driver since it is in good enough shape to
resurrect in staging.
This means that starting with 5.10 this driver will once again be available.
There are some things that I would like to see fixed before moving it out
of staging:
1) Check the driver with checkpatch --strict: I noticed various warnings
that would be good to fix. Let's have this cleaned up before moving it
out of staging.
2) I would like to see the output support fixed.
3) I want to test with my zoran hardware before moving it out of staging.
That said, it will be a few months before I can do that since I don't
have access to the HW at the moment. It depends on when I travel to the
Netherlands, and with the COVID-19 situation I have no idea when that
will be. I hope December, but there is no guarantee.
Since 3) will take 1-2 kernel cycles anyway, that will hopefully allow
for enough time to tackle 1 and 2 while it is still in staging.

As lots of time has elapsed since the very first driver for this card
was merged, and the (Linux) world has changed quite a bit since then,
would it make sense to expose this feature through DRM/KMS instead ?

No, this is really a video output only, not something you would use as a
desktop output. I'm sure you can probably shoehorn it into DRM/KMS, but
it would not be a logical fit for this type of hardware. And besides, it
makes no sense to put a lot of effort in that for such old hardware.

Hans

Ok, this is still on staging, so I'm willing to accept it, but
why aren't you using usleep_range() instead?
mdelay/udelay should be used only when the delay time should
be as precise as possible, as what they do is to keep the CPU
busy during the wait time.
I doubt that this is the case here. So, I would use,
instead, something like:
usleep_range(1000, 2000)
(assuming that 4ms is still a reasonable time for the soft
reset to happen).
