2007-04-27V4L/DVB (5504): Sn9c102: Make driver V4L2 not V4L1Trent Piepho
sn9c102 is a v4l2 driver, except it used a couple v4l1 helper functions. Stop using those functions and depend on V4L2 in Kconfig. Acked-by: Luca Risolia <luca.risolia@studio.unibo.it> Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-04-27V4L/DVB (5502): Sn9c102: more efficient register writing codeTrent Piepho
There were many places in the driver which had long sequences of constant register initializations. These were done with one function call per register. The register address and value were immediate values in the function calls. This is very inefficient, as each register and value take twice the space when they are code, as each includes a push instruction to put it on the stack. There there is the overhead, both size and time, for a function call for each register. It's also quite a few lines of C code to do this. The patch creates a function that writes multiple registers from a list, and a macro that makes it easy to construct a such a list as a const static local to send to the function. This gets rid of quite a bit of C code, and shrinks the driver by around 8k, while at the same time being more efficient.

2007-02-12[PATCH] mark struct file_operations const 4Arjan van de Ven
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

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.

2006-05-12V4L/DVB (3774): Create V4L1 config optionsMauro Carvalho Chehab
V4L1 API is depreciated and should be removed soon from kernel. This patch adds two new options, one to disable V4L1 drivers, and another to disable V4L1 compat module. This way, it would be easy to check what still depends on V4L1 stuff, allowing also to test if app works fine with V4L2 only support. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2006-03-25V4L/DVB (3599a): Move drivers/usb/media to drivers/media/videoMauro Carvalho Chehab
Because of historic reasons, there are two separate directories with V4L stuff. Most drivers are located at driver/media/video. However, some code for USB Webcams were inserted under drivers/usb/media. This makes difficult for module authors to know were things should be. Also, makes Kconfig menu confusing for normal users. This patch moves all V4L content under drivers/usb/media to drivers/media/video, and fixes Kconfig/Makefile entries.
