2008-02-09pvrusb2-dvb: Further clean up dvb init/tear-downMike Isely
From: Mike Isely <isely@pobox.com> Move pvr2_dvb_adapter usage out of the pvrusb2 driver core - it's really private to the pvrusb2-dvb module and nothing outside of the dvb implementation should care about it. Creation / destruction of the pvr2_dvb_adapter instance is now contained entirely within pvrusb2-dvb.c. Signed-off-by: Mike Isely <isely@pobox.com>
2008-02-09pvrusb2-dvb: Don't initialize if device lacks a digital sideMike Isely
From: Mike Isely <isely@pobox.com> In the end we'd like the dvb interface to always be present - even for analog devices (via the mpeg encoder). However right now pvrusb2-dvb won't operate correctly if the hardware doesn't have a digital tuner, so don't initialize the DVB interface unless we know we have a digital tuner.

2008-02-09pvrusb2-dvb: Remove digital_up flagMike Isely

2008-02-09pvrusb2-dvb: Rework module tear-downMike Isely
From: Mike Isely <isely@pobox.com> Rather than making an explicit call to tear down the pvrusb2-dvb module, use the callback in the pvr2_channel structure. This has the advantage that now tear-down only happens when it makes sense. The previous implementation had scenarios where it was possible for the tear-down call to happen without a prior initialization. Signed-off-by: Mike Isely <isely@pobox.com>
2008-02-06pvrusb2: Clean up dvb streaming start/stopMike Isely
From: Mike Isely <isely@pobox.com> Eliminate the need for a separate pvr2_dvb_fh; since in the DVB context there can only ever be a single instance then there is no need for a separate instance to handle streaming state. This simplifies the module. Also move streaming start/stop out of the feed thread and into the driver's main context - which makes it possible for streaming start up failures to be detected by the DVB core. Signed-off-by: Mike Isely <isely@pobox.com>
2008-02-05pvrusb2: Fix oops in pvrusb2-dvbMike Isely
From: Mike Isely <isely@pobox.com> The pvrusb2-dvb feed thread cannot be allowed to exit by itself without first waiting for kthread_should_stop() to return true. Otherwise the driver will have a dangling task_struct context, which will cause a very nasty kernel oops. Signed-off-by: Mike Isely <isely@pobox.com>

2008-02-03pvrusb2: add DVB API frameworkMike Isely
From: Michael Krufky <mkrufky@linuxtv.org> Add basic framework for the DVB API. This is enough to control the tuner & demod of the digital frontend, but the stream & buffer handling is still missing. Additional note from Mike Isely <isely@pobox.com> - also, since these changes are still very experimental arrange for DVB changes to be compiled in via new CONFIG_VIDEO_PVRUSB2_DVB option, for now.

2007-08-02Convert vivi to use videobuf-vmallocMauro Carvalho Chehab
This patch removes the usage of videobuf-dma-sg from vivi driver, using instead videobuf-vmalloc. This way, vivi will be useful for testing the newer method. Reverting this patch won't hurt vivi, since both methods work fine.

2007-08-02Add videobuf-vmallocMauro Carvalho Chehab
Adds a newer videobuf-vmalloc module. This module uses the same videobuf controls, but implements memory allocation based on vmalloc methods. With this method, an USB driver can use video-buf, without needing to request memory from the DMA-safe area.

2007-08-23Adapt drivers to use the newer videobuf modulesMauro Carvalho Chehab
PCI-dependent videobuf_foo methods were renamed as videobuf_pci_foo. Also, videobuf_dmabuf is now part of videobuf-dma-sg private struct. So, to access it, a subroutine call is needed. This patch renames all occurences of those function calls to be consistent with the video-buf split.

2007-08-23Replace video-buf to a more generic approachMauro Carvalho Chehab
video-buf currently does two different tasks: - Manages video buffers with a common code that allows implementing all the V4L2 different modes of buffering; - Controls memory allocations While the first task is generic, the second were written to support PCI DMA Scatter/Gather needs. The original approach can't even work for those video capture hardware that don't support scatter/gather. I did one approach to make it more generic. While the approach worked fine for vivi driver, it were not generic enough to handle USB needs. This patch creates two different modules, one containing the generic video buffer handling (videobuf-core) and another with PCI DMA S/G. After this patch, it would be simpler to write an USB video-buf and a non-SG DMA module.

2007-09-27 bw-qcam: use data_reverse instead of manually poking the control registerMauro Carvalho Chehab

This eliminates the following error message and restores the original intended behavior: parport0 (bw-qcam): use data_reverse for this! Also increases threshold in qc_detect() from 300 to 400, as my camera often results in a count of approx 330. Added a kernel error message to indicate detection failure.

2007-09-19 cafe_ccic: default to allocating DMA buffers at probe timeMauro Carvalho Chehab
From: Andres Salomon <dilinger@queued.net> By default, we allocate DMA buffers when actually reading from the video capture device. On a system with 128MB or 256MB of ram, it's very easy for that memory to quickly become fragmented. We've had users report having 30+MB of memory free, but the cafe_ccic driver is still unable to allocate DMA buffers. Our workaround has been to make use of the 'alloc_bufs_at_load' parameter to allocate DMA buffers during device probing. This patch makes DMA buffer allocation happen during device probe by default, and changes the parameter to 'alloc_bufs_at_read'. The camera hardware is there, if the cafe_ccic driver is enabled/loaded it should do its best to ensure that the camera is actually usable; delaying DMA buffer allocation saves an insignicant amount of memory, and causes the driver to be much less useful.
