2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
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.

2006-09-26V4L/DVB (4518): Allow manually selecting the proper helper driversMauro Carvalho Chehab
There are several boards on V4L that can work with several different helper modules for audio/video encoding/decoding and similar stuff. This patch adds the capability of choicing between autoselecting the pertinent helper modules for each driver, or to manually selecting them.

We should no longer try to load the tda9887 module, because it no longer exists. The tda9887 driver has been merged into the tuner module. This patch removes all instances of request_module("tda9887") from the following video4linux drivers: bttv, cx88, em28xx and saa7134.

2006-06-25V4L/DVB (4205): Merge tda9887 module into tuner.Mauro Carvalho Chehab
Most uses a tda988[5/6/7] IF demodulator as part of the device. Having this as a separate stuff makes harder to configure it, since there are some tda9887 options that are tuner-dependent and should be bound into tuner-types structures. This patch merges tda9887 module into tuner. More work is required to make tuner-types to properly use it. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

This adds support for the older (?) Pinnacle PCTV remotes (with all buttons colored in grey). There's no autodetection for the type of remote, though; saa7134 defaults to the colored one, to use the grey remote the "pinnacle_remote=1" option must be passed to the saa7134 module Signed-off-by: Sylvain Pasche <sylvain.pasche@gmail.com> Signed-off-by: Ricardo Cerqueira <v4l@cerqueira.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
