2011-12-19ALSA: module_param: make bool parameters really boolRusty Russell1-1/+1
module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-10-31sound: fix drivers needing module.h not moduleparam.hPaul Gortmaker1-1/+1
The implicit presence of module.h lured several users into incorrectly thinking that they only needed/used modparam.h but once we clean up the module.h presence, these will show up as build failures, so fix 'em now. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-06-10ALSA: use KBUILD_MODNAME for request_irq argument in sound/pci/*Takashi Iwai1-2/+2
The name argument of request_irq() appears in /proc/interrupts, and it's quite ugly when the name entry contains a space or special letters. In general, it's simpler and more readable when the module name appears there, so let's replace all entries with KBUILD_MODNAME. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-06-10ALSA: Use KBUILD_MODNAME for pci_driver.name entriesTakashi Iwai1-1/+1
The convention for pci_driver.name entry in kernel drivers seem to be the module name or equivalent ones. But, so far, almost all PCI sound drivers use more verbose name like "ABC Xyz (12)", and these are fairly confusing when appearing as a file name. This patch converts the all pci_driver.name entries in sound/pci/* to use KBUILD_MODNAME for more unified appearance. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-03-11ALSA: intel8x0m: wait a bit before warm reset checkPaul Bolle1-1/+2
At every resume a laptop I use prints this message (at KERN_ERR level): ALSA sound/pci/intel8x0m.c:904: AC'97 warm reset still in progress? [0x2] The thing to note here is that 0x2 corresponds to ICH_AC97COLD. Ie, what seems to be happening is that the register involved indicated a warm reset for some time (as the ICH_AC97WARM bit was set) but by the time the warning is printed, and that same register is checked again, that bit is already cleared and only the ICH_AC97COLD bit is still set. It turns out a warm reset needs some time to settle, but it is currently checked right away. The test therefore fails the first time it is done and schedule_timeout_uninterruptible() will be called. Once we return from that jiffies is already (far) past end_time on this laptop, so we exit the loop, print a warning, and exit the function while the warm reset actually succeeded. A way to fix this is to call usleep_range() after writing to the register involved. A handful of tests suggest 500 usecs is a safe value. (This might punish the "finish cold reset" case, but on this laptop such a cold reset apparently never happens, so I can't say for sure.) While we're at it drop the extra single tick from end_time, as it looks rather silly. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2008-04-24[ALSA] Fix possible races at free_irq in PCI driversTakashi Iwai1-6/+2

2008-04-24[ALSA] Fix synchronize_irq() bugs, redundanciesJeff Garzik1-1/+2
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 Howells1-1/+1
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.
