2008-01-31[ALSA] Remove sound/driver.hTakashi Iwai
This header file exists only for some hacks to adapt alsa-driver tree. It's useless for building in the kernel. Let's move a few lines in it to sound/core.h and remove it. With this patch, sound/driver.h isn't removed but has just a single compile warning to include it. This should be really killed in future.

2007-10-16[ALSA] alsa-kernel: schedule_timeout() fixesRene Herman
Fix schedule_timeout() use in alsa-kernel. Mostly just schedule_timeout(1) --> schedule_timeout_uninterruptible(1) The wavefront_synth one fixes the surrounding loop as well. In ymfpci_main, delete a superfluous set_current_state() and in soc/soc-dapm.c replace an _interruptible with _uninterruptible in some debug code; it's not waiting for signals.

2007-07-11PCI: Change all drivers to use pci_device->revisionAuke Kok
Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance. Compile tested with make all{yes,mod}config on x86_64 and i386.

Don't enable power-saving mode on drivers that don't support it. The supporting drivers set AC97_SCAP_POWER_SAVE to scaps at creation of ac97 instance. Currently enable on the following drivers: intel8x0, intel8x0m, atiixp, atiixp-modem, via82xx and via82xx-modem.

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.

2005-11-04[ALSA] Reduce interrupt latency in sound/pci/via82xx.cKarsten Wiese
Modules: VIA82xx driver The change only affects the via823x kind of chips. Here the via8233_pcm_pointer_hw() function (named snd_via8233_pcm_pointer() before) needed to loop until a non zero position is red from the chip. Measurements have shown that more than 200 loops are typically needed on an Athlon64. As io-reads cost many cycles, those loops sum up huge. via8233_pcm_pointer_hw() runs either in interrupt or with interrupts disabled. So it introduces significant interrupt latency. The patch introduces a calculated position value hwptr_done, that is updated by the interrupt routine when a period is completed. It is only used, if the 823x chip returns a zero position, which can't be interpreted reliably. Further optimisation is applied on the 8233 chip's interrupt routine: Only the SGD_SHADOW is read, as it contains all infos needed. We ommit ~5 more register reads that way.
