[PATCH] Fix snd-usb-audio in 32-bit compat environment

2006-03-01T22:36:35+00:00

I'm getting oopses with snd-usb-audio in 32-bit compat environments: control_compat.c:get_ctl_type() doesn't initialize 'info', so 'itemlist[uinfo->value.enumerated.item]' in usbmixer.c:mixer_ctl_selector_info() might access random memory (The 'if ((int)uinfo->value.enumerated.item >= cval->max)' doesn't fix all problems because of the unsigned -> signed conversion.)

[PATCH] usb-audio: don't use empty packets at start of playback

2006-01-31T06:13:17+00:00

Some widespread USB interface chips with adaptive iso endpoints hang after receiving a series of empty packets when they expect data. This completely disables audio playback on those devices. To avoid this, we have to send packets containing silence (zero samples) instead.

[PATCH] Au1550 AC'97 OSS driver spinlock fixes

2005-12-15T22:22:45+00:00

We have found some issues with Au1550 AC'97 OSS driver in 2.6 (sound/oss/au1550_ac97.c), though it also should concern 2.4 driver (drivers/sound/au1550_psc.c). start_dac() grabs a spinlock already held by its caller, au1550_write(). This doesn't show up with the standard UP spinlock impelmentation but when the different one (mutex based) is in use, a lockup happens. And the interrupt handlers also didn't grab the spinlock -- that's OK in the usual kernel but not when the IRQ handlers are threaded. So, they're grabbing the spinlock now (as every correct interrupt handler should do).

[PATCH] unpaged: fix sound Bad page states

2005-11-22T17:13:43+00:00

Earlier I unifdefed PageCompound, so that snd_pcm_mmap_control_nopage and others can give out a 0-order component of a higher-order page, which won't be mistakenly freed when zap_pte_range unmaps it. But many Bad page states reported a PG_reserved was freed after all: I had missed that we need to say __GFP_COMP to get compound page behaviour. Some of these higher-order pages are allocated by snd_malloc_pages, some by snd_malloc_dev_pages; or if SBUS, by sbus_alloc_consistent - but that has no gfp arg, so add __GFP_COMP into its sparc32/64 implementations. I'm still rather puzzled that DRM seems not to need a similar change. Signed-off-by: Hugh Dickins Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] unpaged: sound nopage get_page

2005-11-22T17:13:42+00:00

Something noticed when studying use of VM_RESERVED in different drivers: snd_usX2Y_hwdep_pcm_vm_nopage omitted to get_page: fixed. And how did this work before? Aargh! That nopage is returning a page from within a buffer allocated by snd_malloc_pages, which allocates a high-order page, then does SetPageReserved on each 0-order page within. That would have worked in 2.6.14, because when the area was unmapped, PageReserved inhibited put_page. 2.6.15-rc1 removed that inhibition (while leaving ineffective PageReserveds around for now), but it hasn't caused trouble because.. we've not been freeing from VM_RESERVED at all.

[PATCH] PowerBook 6,1: headphone not detected after suspend

2005-11-16T02:51:50+00:00

ever since suspend to disk works I had the problem that headphone (un)plugging doesn't get detected properly anymore after the first resume. Reloading the module worked around this ever since, however the real cause of the problem was that after a resume the driver only got interrupts on "unplug" not on "plug". Reactivating the headphone status interrupt in tumbler_resume fixes this. This shouldn't cause any trouble with software suspend, but it would be nice if somebody could confirm this: Signed-off-by: Guido Guenther Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras
