* Copyright (c) 2010 by Jarod Wilson <jarod@redhat.com>
|
|
|
|
|
*
|
|
|
|
|
* Based on the original lirc_mceusb and lirc_mceusb2 drivers, by Dan
|
|
|
|
|
* Conti, Martin Blatter and Daniel Melander, the latter of which was
|
|
|
|
|
* in turn also based on the lirc_atiusb driver by Paul Miller. The
|
|
|
|
|
* two mce drivers were merged into one by Jarod Wilson, with transmit
|
|
|
|
|
* support for the 1st-gen device added primarily by Patrick Calhoun,
|
|
|
|
|
* with a bit of tweaks by Jarod. Debugging improvements and proper
|
|
|
|
|
* support for what appears to be 3rd-gen hardware added by Jarod.
|
|
|
|
|
* Initial port from lirc driver to ir-core drivery by Jarod, based
|
|
|
|
|
* partially on a port to an earlier proposed IR infrastructure by
|
|
|
|
|
* Jon Smirl, which included enhancements and simplifications to the
|
|
|
|
|
* incoming IR buffer parsing routines.

[media] mceusb: fix inverted mask inversion logic
As it turns out, somewhere along the way, we managed to invert the
meaning of the tx_mask_inverted flag. Looking back over the old lirc
driver, tx_mask_inverted was set to 0 if the device was in tx_mask_list.
Now we have a tx_mask_inverted flag set to 1 for all the devices that
were in the list, and set tx_mask_inverted to that flag value, which is
actually the opposite of what we used to set, causing set_tx_mask to use
the wrong mask setting option. Since there seem to be more devices with
inverted masks than not (using the original device as the baseline for
inverted vs. normal), lets just call the ones currently marked as
inverted normal instead, and flip the if/else actions that key off of
the inverted flag.
Note: the problem only cropped up if a call to set_tx_mask was made, if
no mask was set, the device would work just fine, which is why this
managed to slip though w/o getting noticed until now.
Tested successfully by myself and Dennis Gilmore.

[media] mceusb: fix inverted mask inversion logic
As it turns out, somewhere along the way, we managed to invert the
meaning of the tx_mask_inverted flag. Looking back over the old lirc
driver, tx_mask_inverted was set to 0 if the device was in tx_mask_list.
Now we have a tx_mask_inverted flag set to 1 for all the devices that
were in the list, and set tx_mask_inverted to that flag value, which is
actually the opposite of what we used to set, causing set_tx_mask to use
the wrong mask setting option. Since there seem to be more devices with
inverted masks than not (using the original device as the baseline for
inverted vs. normal), lets just call the ones currently marked as
inverted normal instead, and flip the if/else actions that key off of
the inverted flag.
Note: the problem only cropped up if a call to set_tx_mask was made, if
no mask was set, the device would work just fine, which is why this
managed to slip though w/o getting noticed until now.
Tested successfully by myself and Dennis Gilmore.

[media] mceusb: fix inverted mask inversion logic
As it turns out, somewhere along the way, we managed to invert the
meaning of the tx_mask_inverted flag. Looking back over the old lirc
driver, tx_mask_inverted was set to 0 if the device was in tx_mask_list.
Now we have a tx_mask_inverted flag set to 1 for all the devices that
were in the list, and set tx_mask_inverted to that flag value, which is
actually the opposite of what we used to set, causing set_tx_mask to use
the wrong mask setting option. Since there seem to be more devices with
inverted masks than not (using the original device as the baseline for
inverted vs. normal), lets just call the ones currently marked as
inverted normal instead, and flip the if/else actions that key off of
the inverted flag.
Note: the problem only cropped up if a call to set_tx_mask was made, if
no mask was set, the device would work just fine, which is why this
managed to slip though w/o getting noticed until now.
Tested successfully by myself and Dennis Gilmore.

V4L/DVB: IR/mceusb: more streamlining of device init
Spent a while last night getting device initialization packet captures
under Windows for all generations of devices. There are a few places
where we were doing things differently, and few things we were doing
that we don't need to do, particularly on gen3 hardware, and I *think*
one of those things is what was locking up my pinnacle hw from time to
time -- at least, its been perfectly well behaved every time its been
plugged in since making this change.
First up, we're adding a bit more to the gen1 init routine here. Its
not absolutely necessary, the hardware works the same both with and
without it, but I'd like to be consistent w/Windows here.
Second, DEVICE_RESET is never called when initializing either of my
gen3 devices, its only called for gen1 and gen2. The bits in the gen3
init after removing that, are safe (and interesting) to run on all
hardware, so there's no more gen3-specific init done, there's instead
a generic mceusb_get_parameters() that is run for all hardware.
Third, the gen3 flag isn't needed. We only care if hardware is gen3
during probe, so I've dropped that from the device flags struct.
Successfully tested on all three generations of mceusb hardware.

[media] mceusb: fix inverted mask inversion logic
As it turns out, somewhere along the way, we managed to invert the
meaning of the tx_mask_inverted flag. Looking back over the old lirc
driver, tx_mask_inverted was set to 0 if the device was in tx_mask_list.
Now we have a tx_mask_inverted flag set to 1 for all the devices that
were in the list, and set tx_mask_inverted to that flag value, which is
actually the opposite of what we used to set, causing set_tx_mask to use
the wrong mask setting option. Since there seem to be more devices with
inverted masks than not (using the original device as the baseline for
inverted vs. normal), lets just call the ones currently marked as
inverted normal instead, and flip the if/else actions that key off of
the inverted flag.
Note: the problem only cropped up if a call to set_tx_mask was made, if
no mask was set, the device would work just fine, which is why this
managed to slip though w/o getting noticed until now.
Tested successfully by myself and Dennis Gilmore.

V4L/DVB: IR/mceusb: more streamlining of device init
Spent a while last night getting device initialization packet captures
under Windows for all generations of devices. There are a few places
where we were doing things differently, and few things we were doing
that we don't need to do, particularly on gen3 hardware, and I *think*
one of those things is what was locking up my pinnacle hw from time to
time -- at least, its been perfectly well behaved every time its been
plugged in since making this change.
First up, we're adding a bit more to the gen1 init routine here. Its
not absolutely necessary, the hardware works the same both with and
without it, but I'd like to be consistent w/Windows here.
Second, DEVICE_RESET is never called when initializing either of my
gen3 devices, its only called for gen1 and gen2. The bits in the gen3
init after removing that, are safe (and interesting) to run on all
hardware, so there's no more gen3-specific init done, there's instead
a generic mceusb_get_parameters() that is run for all hardware.
Third, the gen3 flag isn't needed. We only care if hardware is gen3
during probe, so I've dropped that from the device flags struct.
Successfully tested on all three generations of mceusb hardware.
