* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-0516-27/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [ALSA] AdLib FM card driverRene Herman2006-03-313-0/+172
| | | | | | | | | | | | | | | Attached you'll find an ALSA driver for AdLib FM cards. An AdLib card is just an OPL2, which was already supported by sound/drivers/opl3, so only very minimal bus-glue is needed. The patch applies cleanly to both 2.6.16 and 2.6.16-mm1. The driver has been tested with an actual ancient 8-bit ISA AdLib card and works fine. It also works fine for an OPL3 {,emulation} as still found on many ISA soundcards but given that AdLib cards don't have their own mixer, upping the volume from 0 might be a problem without the card driver already loaded and driving the OPL3.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modules: ES18xx driver Forth of 4 es18xx.c patches culminating in Zoom Video support. This patch adds Zoom Video support for those chipsets that support it. Testing: This work was initially done on the source from the Debian Sarge ALSA package, then tested on an ES1879. I could not test the Zoom Video function for an ES1878 or ES1869. Patches were created against the Sarge code and then edited to apply correctly to the ALSA cvs code. Lastly the patched ALSA cvs code was test for successful compilation. No additional testing was done on the ALSA cvs version. One quirk (noted in my comments below) is that apparently the datasheet is wrong for one of the ES1879 Zoom Video 'enable' bits, because 1) if you set this bit it messes up PCM playback (speaker_test play a lower frequency) 2) even if you don't set this bit Zoom Video still works. I added a control to toggle the bit on just in case there might be a version of the ES1879 that requires it, but I expect noone will need it.
