2009-06-15ALSA: intel8x0 - Fix PCM position crazinessTakashi Iwai
The PCM pointer callback sometimes returns invalid positions and this screws up the hw_ptr updater in PCM core. Especially since now the jiffies check is optional with xrun_debug, the invalid position is handled as is, and causes serious sound skips, etc. This patch simplifies the position-fix strategy in intel8x0 to be more robust: - just falls back to the last position if bogus position is detected - another sanity check for the backward move of the position due to a race of register update and the base-index update This patch is applicable also for 2.6.30.

While cleaning up quirks, I noticed that there is a duplicated quirk for the SSID 0x103c0934. Looking back through the bug reports, I've concluded that there is only one necessary quirk (hp_mute_led), so this patch removes the conflicting one.

- use monotonic posix clock to measure time - try to avoid reading zero from PICB (position in current buffer) register - show also measured samples - when clock is near 41000 or 44100, use exactly these values (they appears to be reference clocks for hardware manufacturers) Signed-off-by: Jaroslav Kysela <perex@perex.cz>

2008-04-24[ALSA] Fix synchronize_irq() bugs, redundanciesJeff Garzik
free_irq() calls synchronize_irq() for you, so there is no need for drivers to manually do the same thing (again). Thus, calls where sync-irq immediately precedes free-irq can be simplified. However, during this audit several bugs were noticed, where free-irq is preceded by a "irq >= 0" check... but the sync-irq call is not covered by the same check. So, where sync-irq could not be eliminated completely, the missing check was added. Signed-off-by: Jeff Garzik <jgarzik@redhat.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

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.
