2007-07-02Fix v4l-dvb backward compatibilityMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Due to several internal API changes on kernel, kernel backward compatibility were lost. Basically, compat.h should be the last include for it to work properly. This patch basically reorders kernel headers to allow backward compat to work fine. Also: Some includes were added after some non-include macros, on old drivers. Better to keep all includes at the beginning of the files. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2006-10-21IRQ: Maintain regs pointer globally rather than passing to IRQ handlersMauro Carvalho Chehab
Kernel-sync: This patch is required to allow compilation of the tree with kernel 2.6.19. This is the original description of the original patch, signed by David Howells <dhowells@redhat.com>: 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>

2006-10-06cx88-blackbird module is rejected during probe.Steven Toth
From: Steven Toth <stoth@hauppauge.com> If the last cx88 board probed is not backbird based, and a previous board was, the entire module is unloaded leading to an oops during mpeg_open on the first /dev/videoN device. Signed-off-by: Steven Toth <stoth@hauppauge.com>
2006-10-05Bugfix: Select the correct cx8802_dev when enumerating by CX88_MPEG_typeSteven Toth
From: Steven Toth <stoth@hauppauge.com> 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. Signed-off-by: Steven Toth <stoth@hauppauge.com>

2006-09-27Dynamic cx88 mpeg port management for HVR1300 MPEG2/DVB-T support. Steven Toth
From: Steven Toth <stoth@hauppauge.com> 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. Signed-off-by: Steven Toth <stoth@hauppauge.com>
2006-09-25cx88: rename mpeg capability flags from CX88_BOARD_FOO to CX88_MPEG_FOOMichael Krufky
From: Michael Krufky <mkrufky@linuxtv.org> The flags for mpeg capabilities are sub-optimally named as CX88_BOARD_DVB and CX88_BOARD_BLACKBIRD, which creates some confusion. This patch renames the above to CX88_MPEG_DVB and CX88_MPEG_BLACKBIRD.

From: Mauro Carvalho Chehab <mchehab@infradead.org> Video_buf were concerned to allow PCI devices to be used as video capture devices.
