Enhance the dvb-pll definition of the fmd1216 tuner by adding an init sequence
and a sleep sequence.
The init sequence sets the AGC control register to 0xa0, selecting the fast
time constant and 112 dBuV take-over point. This the recommended value for
DVB-T operation.
The sleep sequence sets bit P4 (which is believed to turn the analog
demodulator on), turns off the tuning voltage, and sets the AGC control
register to 0x60 (external AGC voltage, the recommended value for analog
operation).
The existing dvb-pll users in the cx88 driver, listed below, will gain these
init and sleep sequences.
CX88_BOARD_HAUPPAUGE_HVR1100 Hauppauge WinTV-HVR1100 DVB-T/Hybrid
CX88_BOARD_HAUPPAUGE_HVR1100LP Hauppauge WinTV-HVR1100 DVB-T/Hybrid (Low Profi

CX88_BOARD_HAUPPAUGE_HVR1300 Hauppauge WinTV-HVR1300 DVB-T/Hybrid MPEG Encod
This non-dvb-pll user in the cx88 driver should only gain the sleep sequence,
as it already had an equivalent init sequence. The non-dvb-pll code for this
user is removed.
X88_BOARD_DNTV_LIVE_DVB_T_PRO digitalnow DNTV Live! DVB-T Pro
In these saa7134 driver, these non-dvb-pll users are converted to use dvb-pll:
SAA7134_BOARD_MD7134 Medion 7134
SAA7134_BOARD_ASUS_EUROPA2_HYBRID Asus Europa2 OEM
The saa7134 functions philips_fmd1216_tuner_init(),
philips_fmd1216_tuner_sleep(), and philips_fmd1216_tuner_set_params() are
deleted and the dvb-pll versions are used.
This should result in equivalent sleep, init, and tuning sequences being sent
to the tuner.
For the cxusb driver, only one board is effected:
USB_PID_MEDION_MD95700 Medion MD95700
This board used dvb_usb_tuner_init_i2c() and dvb_usb_tuner_set_params_i2c()
for init and tuning, respectively. These functions are effectively the same
as the dvb-pll versions. They call a tuner pass control function defined at
the dvb-usb level, but this does not matter, as this card does not have a
tuner pass control function (only the dib3000mb does). This board will gain
the sleep sequence, while init and tuning should be unchanged.

If cx88 support is compiled into the kernel while vp3054 is left as a module,
the kernel will fail to link. Adjust the existing "#if" code in cx88 so
that it won't consider vp3054 to be supported in this case.
It might make sense to move vp3054 selection into the "customisation" menu
instead of a cx88 sub-option (though this is a cx88 feature, there is no extra
chip involved).
It might also make sense to use dvb_attach() to load vp3054 support.

Currently, the freezer treats all tasks as freezable, except for the kernel
threads that explicitly set the PF_NOFREEZE flag for themselves. This
approach is problematic, since it requires every kernel thread to either
set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
care for the freezing of tasks at all.
It seems better to only require the kernel threads that want to or need to
be frozen to use some freezer-related code and to remove any
freezer-related code from the other (nonfreezable) kernel threads, which is
done in this patch.
The patch causes all kernel threads to be nonfreezable by default (ie. to
have PF_NOFREEZE set by default) and introduces the set_freezable()
function that should be called by the freezable kernel threads in order to
unset PF_NOFREEZE. It also makes all of the currently freezable kernel
threads call set_freezable(), so it shouldn't cause any (intentional)
change of behaviour to appear. Additionally, it updates documentation to
describe the freezing of tasks more accurately.

In order to find all possibly affected files, I searched for all

or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the

The code of the dvb-pll driver and the lgh06xf driver is nearly
identical. The main difference is that the lgh06xf driver would set the
AGC TOP value on every tune call. The dvb-pll driver now has the ability
to set the AGC TOP when the front-end device is opened, which is a better
way to go about it. By using this ability of dvb-pll, the lgh06xf driver
is made unnecessary.
There is one other difference. dvb-pll will probe for the presence of an
I2C pll chip by doing a one byte read, the lgh06xf driver did not do
this. In some devices the PLL is not reachable over I2C at the timer the
tuner is attached. Some more initialization, such as firmware loading,
must take place first. None of the devices using a LG-H06xF should have
this problem.

The out of tree v4l-dvb build system didn't always override the kernel's
configuration settings with v4l-dvb's settings correctly. To work around
this, makefiles would define some new macro based on the setting of a
config variable. e.g. the pwc Makefile would define CONFIG_PWC_DEBUG if
CONFIG_USB_PWC_DEBUG (which is defined via Kconfig) was set.
The v4l-dvb build system should now always override correctly, and this
is no longer necessary. This patch gets ride of these extra defines and

The direct register access ioctls were defined as kernel internal only,

VIDIOC_INT_[SG]_REGISTER is renamed to VIDIOC_DBG_[SG]_REGISTER
Definition of ioctl and struct v4l2_register is moved from v4l2-common.h

Types used in struct v4l2_register are changed to the userspace
exportable versions (u32 -> __u32, etc).
Use of VIDIOC_DBG_S_REGISTER requires CAP_SYS_ADMIN permission, so move
the check into the video_ioctl2() dispatcher so it doesn't need to be

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.
To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

GOLD {Q,T}). This way the set_params function from dvb-pll is used.
dvb_attach() is in turn used on dvb_pll_attach(), eliminating some static
dependencies on dvb-pll. There are still a couple static dependencies on
dvb-pll remaining.

This patch creates a new atsc tuner module for the LG TDVS-H06xF ATSC tuners,
called lgh06xf. The purpose of this change is to reduce some duplicated
code, and to allow the lgh06xf tuner code to take advantage of dvb_attach().
As a side effect, the dependency of dvb-bt8xx on dvb-pll has been removed,
since the lgh06xf module itself will use dvb-pll, while remaining optional
for the dvb-bt8xx driver through the use of DVB_FE_CUSTOMISE

Some cx88-blackbird boards use an external adc, but not necessarily
for all inputs. Thus, this needs to be configurable on the card level
for each input.
This patch allows for the usage of the external adc to be determined
by a bit setting in the cx88_input struct for cards based on the cx88
blackbird design.

A bug in cx8802_get_driver() meant that in multiboard environments, when testing
frontends on the non primary board, the incorrect device was returned resulting
in "Unsupported value in .mpeg.." messages. Depending on the electrical design
of the hardware (serial, parallel, rising/falling edge detect), transport would
still be delivered and the problem went unnoticed.
This patch ensures the correct instance of cx8802_dev is returned.

A series of patches to change the cx88 framework to allow the
PCI mpeg port to be shared dynamically between different
types of drivers or applications. This patch changes the cx88-dvb
and cx88-blackbird drivers to become 'sub drivers' of a higher
single cx88-mpeg driver.
The cx88-mpeg driver is a superset of the previous cx88-mpeg/blackbird
drivers and now owns the IRQ. cx88-dvb/blackbird now become mini drivers,
registering themselves with cx88-mpeg through a standard interface with
callbacks.
Sub drivers request access to hardware via the cx88-mpeg driver. In turn
the cx88-mpeg driver determines whether the hardware is busy and accepts
or refuses the request, grant access using callbacks into the sub drivers.
The net effect is that you are no longer able to tamper with the mpeg port
from multiple different applications at the same time, potentially breaking
a live mpeg2 hardware encoding or dvb stream.
The mechanism extends to enable multiple dvb frontends to be registered
and share the single resource.

Add support for the advanced debugging ioctls, to allow access to the
cx88 registers from userspace. Only i2c_id == 0 is supported, for access
to the cx88 adapter itself. There isn't any support for access to I2C
clients of the adapter. Most of them don't have R/W registers anyway,
and its necessary to use i2c-dev to talk to them from userspace.

Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.
The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around. On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).
Where appropriate, an arch may override the generic storage facility and do
something different with the variable. On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.
Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions. Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller. A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.
I've build this code with allyesconfig for x86_64 and i386. I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.
This will affect all archs. Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
struct pt_regs *old_regs = set_irq_regs(regs);
And put the old one back at the end:
set_irq_regs(old_regs);
Don't pass regs through to generic_handle_irq() or __do_IRQ().
In timer_interrupt(), this sort of change will be necessary:
- update_process_times(user_mode(regs));
- profile_tick(CPU_PROFILING, regs);
+ update_process_times(user_mode(get_irq_regs()));
+ profile_tick(CPU_PROFILING);
I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().
Some notes on the interrupt handling in the drivers:
(*) input_dev() is now gone entirely. The regs pointer is no longer stored in
the input_dev struct.
(*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
something different depending on whether it's been supplied with a regs
pointer or not.
(*) Various IRQ handler function pointers have been moved to type
irq_handler_t.

Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
This patch changes the setting of the cx2388x notch filter to match that of
the video capture sample frequency, removing some annoying interference
lines THAT would appear when capturing composite video. This has been tested
in PAL and NTSC TV norms.
It sets the Y/C separation luma notch filter, which removes the chroma signal
from the luma signal when using a composite input.
The luma notch filter operates at the video decoder's frequency, not the ADC's
frequency or at the frequency of the scaled video. Y/C separation happens after
the sample rate converter, before video scaling.
The datasheet provides plots of the filter response for three _video decoder_
frequencies, 4x Fsc, square pixel, and ccir601. These are the same three
frequencies for the notch filter control. It seems pretty clear that this
filter should be set based on the video decoder frequency. The cx88 driver
always uses a video decoder frequency of 4xFsc.
