      V4L/DVB (9885): drivers/media Kconfig's: fix bugzilla #12204 · 8b21c1e9
      由 Mauro Carvalho Chehab 提交于 
      When the tuner modules were moved to common/tuners, a separate customize
option were added for tuners. However, the automatic selection of the
tuners were still using the older option.

This causes that the automatic selection to fail, if DVB_FE_CUSTOMISE is
selected. Also, since those tuners are now under MEDIA_TUNER_CUSTOMIZE
menu, if you unset MEDIA_TUNER_CUSTOMIZE, you can't manually select the
tuners.

This patch fixes this error by replacing DVB_FE_CUSTOMISE by
MEDIA_TUNER_CUSTOMIZE on all places were a tuner is selected.

The patch were generated by this small script:

for i in `find drivers/media -name Kconfig`; do
  cat $i|perl -ne 's/(MEDIA_TUNER.*)DVB_FE_CUSTOMISE/\1MEDIA_TUNER_CUSTOMIZE/; print $_' >a
  mv a $i
done

Also, manually reordered the tuner entries.

      V4L/DVB (9356): [PATCH] saa7134: fix resource map sanity check conflict · d522af58
      由 Suresh Siddha 提交于 
      Impact: driver could possibly stomp on resources outside of its scope

{mchehab@redhat.com: I got two versions of the same patch (identical,
except for whitespacing). One authored by Andy Burns and another
authored by Suresh Siddha. Due to that, I'm applying the one that has
less CodingStyle errors. I'm also adding both comments and the SOB's for
both patches, since they are both interesting}

Suresh Siddha commented:

  Alexey Fisher reported:

  > resource map sanity check conflict: 0xcfeff800 0xcff007ff 0xcfe00000
  > 0xcfefffff PCI Bus 0000:01

  BAR base is located in the middle of the 4K page and the hardcoded
  size argument makes the request span two pages causing the conflict.

  Fix the hard coded size argument in ioremap().

Andy Burns commented:

  I have already sent this patch on the linux-dvb list, but it didn't get
  much attention, so re-sending direct, I hope you all don't mind.

  While attempting to run mythtv in a xen domU, I encountered problems
  loading the driver for my saa7134 card, with an error from ioremap().

  This error was due to the driver allocating an incorrectly sized mmio
  area, which was trapped by xen's permission checks, but this would go
  un-noticed on a kernel without xen.

  My card has a 1K sized mmio area, I've had information that other cards
  have 2K areas, perhaps others have different sizes, yet the driver
  always attempts to map 4K.  I realise that the granularity of mapping is
  the page size, which typically would be 4K, but unless the card's base
  address happens to fall on a 4K boundary (mine does not) then the
  base+4K will end up spanning two pages, and this is when the error
  occurs under xen.

  My patch uses the pci_resource_len macro to determine the size required
  for the user's particular card, instead of the hardcoded 4K value. I've
  tested with a couple of printk() inside ioremap() that the start address
  and size do get rounded to the closest page boundary.

  With this patch I am able to successfully load the saa7134 driver and
  run mythtv under xen with my card, subject to correct pollirq settings
  in case of shared IRQ, I am still seeing occasional DMA panics, which I
  think are related to swiotlb handling by dom0/domU, usually the panic
  occurs when changing mux, once tuned to a mux, 12 hour continuous
  recordings are possible without errors.

      V4L/DVB (9327): v4l: use video_device.num instead of minor in video%d · c6330fb8
      由 Hans Verkuil 提交于 
      The kernel number of a v4l2 node (e.g. videoX, radioX or vbiX) is now
independent of the minor number. So instead of using the minor field
of the video_device struct one has to use the num field: this always
contains the kernel number of the device node.

I forgot about this when I did the v4l2 core change, so this patch
converts all drivers that use it in one go. Luckily the change is
trivial.

      V4L/DVB (9227): MFE: Add multi-frontend mutual exclusion · 59b1842d
      由 Darron Broad 提交于 
      This add frontend R/W mutual exclusion.
Prior to this point in time it was possible to open both
frontends simultaneously which an MFE card cannot support.

In order to stop this, a delayed open is performed which
has the following function:

-  Return EBUSY after a configurable amount of time
   if a frontend is unavailable due to the other being
   in use.

-  Only allow opening of a frontend if the kernel thread
   of the other has stopped.

This solution was chosen to allow switching between
frontends to work as seamlessly as possible. When both
frontends are actually opened simultaneously then one
will only open, but if quick switching is performed
between one of many then the new open will succeed in
a clean fashion rather than interrupting a kernel
thread.

      A number of reference to videobuf_dvb_get_frontend used an invalid
index. This has been fixed.

The section for the HVR3000 in advise_acquire was redundant as
the same logic is used on the HVR4000. This has been removed
and both cards now use the same function.

A number of small errors and whitespace errors are also fixed.

      V4L/DVB (9222): S2API: Add Multiple-frontend on a single adapter support. · 363c35fc
      由 Steven Toth 提交于 
      A detailed description from the original patches 2 years ago:

"The WinTV-HVR3000 has a single transport bus which is shared between
a DVB-T and DVB-S modulator. These patches build on the bus acquisition
cx88 work from a few weeks ago to add support for this.

So to applications the HVR3000 looks like this:
/dev/dvb/adapter0/fe0 (cx24123 DVB-S demod)
/dev/dvb/adapter0/fe1 (cx22702 DVB-T demod)

Additional boards continue as before, eg:
/dev/dvb/adapter1/fe0 (lgdt3302 ATSC demod)

The basic change is removing the single instance of the videobuf_dvb in
cx8802_dev and saa7134_dev(?) and replacing it with a list and some
supporting functions.

*NOTE* This branch was taken before v4l-dvb was closed for 2.6.19 so
two or three current cx88 patches appear to be reversed by this tree,
this will be cleaned up in the near future. The patches missing change
the mutex handing to core->lock, fix an enumeration problem."

It should be recognised that a number of people have been maintaining
this patchset. Significant levels of Kudos to everyone one involved,
including but not limited to:

Darron Broad
Fabio M. Di Nitto
Carlo Scarfoglio
Hans Werner

Without the work of these people, and countless others, my two year old
patches would of died on the Mercurial linuxtv.org vine a long time
ago.

TODO: Revise these patches a little further so that the need for
demux1 and dvr0 is optional, not mandatory on the HVR3000.

HISTORY (darron):
This is the last update to MFE prepared by Hans which is based
upon the `scratchpad' diff created by Carlo.
All MFE work prior to that point must be attributed to Fabio
who ported and maintained Steve's original patch up to that
time.
