* V4L/DVB (5361): Dvb-pll: Fix Kconfig files and allow dvb-pll to be optionalTrent Piepho2007-04-27
| | | | | | | | | | | | | | | | | | | | A number of drivers selected DVB_PLL when they did not need it, and some that did need it did not select it. The DVB_PLL option is given a name and help text, so that it will show up in the config menu. DVB_PLL support can be turned on if an out-of-tree driver needs it. The standard dvb fe customization support is added to dvb-pll.h. Since all modules which select DVB_PLL do so unconditionally, it is not possible to turn dvb-pll off when an enabled module selects it, unlike most of the other frontend/tuner drivers. This is because the users of dvb-pll have static references to dvb-pll symbols other than the attach function. If these references are removed, then dvb-pll will be disablable as the other frontend/tuner drivers are.

* i2c: Declare more i2c_adapter parent devicesJean Delvare2007-02-13
| | | | | | | | | | | | | | | Declare the parent device of i2c_adapter devices each time we can easily do so. It makes the i2c_adapter appear at the right place in the device tree, rather than as a platform device.

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* V4L/DVB (4028): Change dvb_frontend_ops to be a real field instead of a ↵Patrick Boettcher2006-06-25
| | | | | | | | | | | | | | | | | | pointer field inside dvb_frontend The dvb_frontend_ops is a pointer inside dvb_frontend. That's why every demod-driver is having a field of dvb_frontend_ops in its private-state-struct and using the reference for filling the pointer-field in dvb_frontend. - It saves at least two lines of code per demod-driver, - reduces object size (one less dereference per frontend_ops-access), - be coherent with dvb_tuner_ops, - makes it a little bit easier for newbies to understand how it works and - avoids stupid mistakes because you would have to copy the dvb_frontend_ops always, before you could assign the static pointer directly, which was dangerous.

* V4L/DVB (3762): Add sysfs device links to dvb devicesAndrew de Quincey2006-06-25
| | | | | | | | | | | | | | | | | | | | | | | | Currently in /sys/class/dvb/dvbX.demuxY/ we have: dev uevent With the patch, we have (for a PCI DVB device): dev device -> ../../../devices/pci0000:00/0000:00:1e.0/0000:03:0d.0 uevent So userspace tools can (finally) work out which physical device a DVB adapter refers to. Previously you had to kinda look through dmesg and hope that it hadn't been dumped out of the buffer. This makes debugging a lot easier if the system has been up for a long time! This is done by adding an extra 'struct device *' parameter to dvb_register_adapter(). It will work with any kind of standard linux 'device'. Additionally, if someone has an embedded system which does things differently, they can simply supply 'NULL' and the behaviour will be as before - the link will simply not appear.

* [PATCH] I2C: Kill i2c_algorithm.id (6/7)Jean Delvare2005-09-05
| | | | | | | | | | | | | | | | | | | | | | In theory, there should be no more users of I2C_ALGO_* at this point. However, it happens that several drivers were using I2C_ALGO_* for adapter ids, so we need to correct these before we can get rid of all the I2C_ALGO_* definitions. Note that this also fixes a bug in media/video/tvaudio.c: /* don't attach on saa7146 based cards, because dedicated drivers are used */ if ((adap->id & I2C_ALGO_SAA7146)) return 0; This test was plain broken, as it would succeed for many more adapters than just the saa7146: any those id would share at least one bit with the saa7146 id. We are really lucky that the few other adapters we want this driver to work with did not fulfill that condition.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.
