This function is not specific to mmap, hence the rename. Add a check whether we are not streaming or reading (for read mode that uses the stream queue) before freeing anything. Signed-off-by:

These functions allocate videobuf_buffer structures only. Renaming in order to prevent confusion with functions allocating actual video buffer memory. Rename the functions in videobuf-core.h videobuf-dma-sg.c as well. Signed-off-by:

Some (North American) providers use a non-standard mode called "8psk turbo fec". Since there is no flag in the driver that would allow an application to determine whether a particular device can handle "turbo fec", the attached patch introduces FE_CAN_TURBO_FEC. Since there is no flag in the SI data that would indicate that a transponder uses "turbo fec", VDR will assume that all 8psk transponders on DVB-S use "turbo fec". Tested-by:

Add a mutex_unlock missing on the error path.

My previous patch to depend on FONTS was not sufficient since FONTS is boolean. VIDEO_VIVI needs to depend on a tristate so that it won't be enabled as =y when framebuffer is built as modular, so modify it to depend on the same symbols that FONTS depends on, which are FRAMEBUFFER_CONSOLE || STI_CONSOLE. Fixes this build error when VIDEO_VIVI=y and FRAMEBUFFER_CONSOLE=m: vivi.c:(.init.text+0x7205): undefined reference to `find_font' Signed-off-by:

I have pinnacle hardware now. None of this pinnacle-specific crap is at all necessary (in fact, some of it needed to be removed to actually make it work). The only thing unique about this device is that it often transfers inbound data w/a header of 0x90, meaning 16 bytes of IR data following it, so I had to make adjustments for that, and now its working perfectly fine.

The first-gen mceusb device init code, while mostly functional, had a few issues in it. This patch does the following: 1) removes use of magic numbers 2) eliminates mapping of memory from stack 3) makes debug spew translator functional Additionally, this clean-up revealed that we cannot read the proper default tx blaster bitmask from the device, we do actually have to initialize it ourselves, which requires use of a somewhat gross list-based mask inversion check. This patch also removes the entirely unnecessary use of struct ir_input_state. Also supersedes two earlier patches that also touched on first-gen cleanup, but were partially botched. This one actually compiles, works, etc., I swear. ;) Signed-off-by:

Was using input_unregister_device directly, instead of using ir_input_unregister, which tears down a bunch of other things in addition to eventually calling input_unregister_device. Signed-off-by:

This patch moves the state from each raw decoder into the ir_raw_event_ctrl struct. This allows the removal of code like this: spin_lock(&decoder_lock); list_for_each_entry(data, &decoder_list, list) { if (data->ir_dev == ir_dev) break; } spin_unlock(&decoder_lock); return data; which is currently run for each decoder on each event in order to get the client-specific decoding state data. In addition, ir decoding modules and ir driver module load order is now independent. Centralizing the data also allows for a nice code reduction of about 30% per raw decoder as client lists and client registration callbacks are no longer necessary (but still kept around for the benefit of the lirc decoder). Out-of-tree modules can still use a similar trick to what the raw decoders did before this patch until they are merged. Signed-off-by:David Härdeman <david@hardeman.nu> Acked-by:

With this change, it is now possible to do something like: su -c 'echo "none +rc-5 +nec" > /sys/class/rc/rc1/protocols' This prevents the need of multiple opens, one for each protocol change, and makes userspace application easier. Signed-off-by: -

Writing "none" to /dev/class/rc/rc*/protocols will disable all protocols. This allows an easier setup, from userspace, as userspace applications don't need to disable protocol per protocol, before enabling a different set of protocols. Signed-off-by: -

While rc-5 and rc-6 protocols are generally abreviated as "rc5" and "rc6", previous sysfs nodes uses rc-5 and rc-6 for the Philips protocols. This is consistent with the protocol nomenclature given by the original Philips spec: "Remote control system RC-5" (doc. Nr. 9398 706 23011). Also, rc5 is the name of a widely known cryptography protocol. So, the better is to keep referring to those protocols as "rc-5" and "rc-6". Signed-off-by: -

With the current logic, each raw decoder needs to add a copy of the exact same sysfs code. This is both unnecessary and also means that (re)loading an IR driver after raw decoder modules have been loaded won't work as expected. This patch moves that logic into ir-raw-event and adds a single sysfs file per device. Reading that file returns something like: "rc5 [rc6] nec jvc [sony]" (with enabled protocols in [] brackets) Writing either "+protocol" or "-protocol" to that file will enable or disable the according protocol decoder. An additional benefit is that the disabling of a decoder will be remembered across module removal/insertion so a previously disabled decoder won't suddenly be activated again. The default setting is to enable all decoders. This is also necessary for the next patch which moves even more decoder state into the central raw decoding structs. Signed-off-by:
