* ALSA: rawmidi - Add open check in rawmidi callbacksTakashi Iwai2008-11-031-0/+8
| | | | | | | | | | | The drivers (e.g. mtpav) may call rawmidi functions in irq handlers even though the streams are not opened. This results in Oops or panic. This patch adds the rawmidi state check before actually operating the rawmidi buffers. Tested-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Takashi Iwai <tiwai@suse.de>

* sound: make OSS sound core optionalTejun Heo2008-08-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | sound/sound_core.c implements soundcore.ko and contains two parts - sound_class which is shared by both ALSA and OSS and device redirection support for OSS. It's always compiled when any sound support is enabled although it's necessary only when OSS (the actual one or emulation) is enabled. This is slightly wasteful and as device redirection always registers character device region for major 14, it prevents alternative implementation. This patch introduces a new config SOUND_OSS_CORE which is selected iff OSS support is actually necessary and build the OSS core part conditionally. If OSS is disabled, soundcore merely contains sound_class but leaving it that way seems to be the simplest approach as otherwise sound_class should be in ALSA core file if OSS is disabled but should be in soundcore if OSS is enabled. Also, there's also the user confusion factor. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
* ALSA: Allocate larger pages in sgbufTakashi Iwai2008-08-252-16/+72
| | | | | | | | | | | | | | | | | | | | | | Most hardwares have limited buffer-descriptor table length. This also restricts the max buffer size of the sound driver. For example, snd-hda-intel has 1MB buffer size limit, and this is because it can have at most 256 BDL entries. For supporting larger buffers, we need to allocate larger pages even for sg-buffers. This patch changes the sgbuf allocation code to try to allocate larger pages first. At each head of the allocated pages, the number of allocated pages is stored in the lowest bits of the corresponding entry of the table addr field. This change isn't visible as long as the driver uses snd_sgbuf_get_addr() helper. Also, the patch adds a new function, snd_pcm_sgbuf_get_chunk_size(). This returns the size of the chunk on continuous pages starting at the given position offset. If the chunk reaches to a non-continuous page, it returns the size to the boundary.

* ALSA: Fix limit of 8 PCM devices in SNDRV_CTL_IOCTL_PCM_NEXT_DEVICEPawel MOLL2008-08-012-15/+37
| | | | | | | | | | | | | | | | | | | | | When compiled with CONFIG_SND_DYNAMIC_MINORS the ALSA core is fine to have more than 8 PCM devices per card, except one place - the SNDRV_CTL_IOCTL_PCM_NEXT_DEVICE ioctl, which will not enumerate devices > 7. This patch fixes the issue, changing the devices list organisation. Instead of adding new device to the tail, the list is now kept always ordered (by card number, then device number). Thus, during enumeration, it is easy to discover the fact that there is no more given card's devices. Additionally the device field of struct snd_pcm had to be changed to int, as its "unsignednity" caused a lot of problems when comparing it to potentially negative signed values.

Additionally the device field of struct snd_pcm is now int, instead of unsigned int, as there is no obvious reason for keeping it unsigned. This caused a lot of problems with comparing this value with other (almost always signed) variables. There is just one more place where device number is unsigned - in struct snd_pcm_info, which should be also sorted out in future.

* ALSA: Build jack detectionMark Brown2008-07-292-0/+7
| | | | | | | | | | | | | | | | | | | | Since jack detection requires the input subsystem which may not be desired on small systems it is not built unless required by a driver that is being built. Drivers using jack detection should use a pattern like this: config SND_FOO tristate "..." ... select SND_JACK if INPUT=y || INPUT=SND to ensure that the jack detection API is enabled if the input subsystem is. If the input subsystem is not enabled then a stub version of the API is provided.

* ALSA: Add jack reporting APIMark Brown2008-07-291-0/+163
| | | | | | | | | | | | | | | | | | | | | | Currently very few systems provide information about jack status to user space, even though many have hardware facilities to do detection. Those systems that do use an input device with the existing SW_HEADPHONE_INSERT switch type to do so, often independently of ALSA. This patch introduces a standard method for representing jacks to user space into ALSA. It allows drivers to register jacks for a sound card with the input subsystem, binding the input device to the card to help user space associate the input devices with their sound cards. The created input devices are named in the form "card longname jack" where jack is provided by the driver when allocating a jack. By default the parent for the input device is the sound card but this can be overridden by the card driver. The existing user space API with SW_HEADPHONE_INSERT is preserved.

* Revert "pcm_native.c: remove unused label"Linus Torvalds2008-08-061-0/+1
| | | | | | | | | | | | | | | | | | This reverts commit 680db0136e0778a0d7e025af7572c6a8d82279e2. The label is actually used, but hidden behind CONFIG_SND_DEBUG and the horrible snd_assert() macro. That macro could probably be improved to be along the lines of #define snd_assert(expr, args...) do { if ((void)(expr),0) { args; } } while (0) or similar to make sure that we always both evaluate 'expr' and parse 'args', but while gcc should optimize it all away, I'm too lazy to really verify that.

* PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architecturesAndrea Righi2008-07-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit boundary. For example: u64 val = PAGE_ALIGN(size); always returns a value < 4GB even if size is greater than 4GB. The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for example): #define PAGE_SHIFT 12 #define PAGE_SIZE (_AC(1,UL) << PAGE_SHIFT) #define PAGE_MASK (~(PAGE_SIZE-1)) ... #define PAGE_ALIGN(addr) (((addr)+PAGE_SIZE-1)&PAGE_MASK) The "~" is performed on a 32-bit value, so everything in "and" with PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary. Using the ALIGN() macro seems to be the right way, because it uses typeof(addr) for the mask. Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in include/linux/mm.h.
