Use the wss_dout function which does not mess shadowed register values during chip probing. Otherwise, user ends up with stupid mixer settings after driver loading. Signed-off-by:

- more register naming work - finally figured out that weird CR register stuff (and did I mention that I hate _really_ undecipherable open-coded values?) - fix handling of IRQ sharing in interrupt handler (hopefully properly, otherwise I'd be grateful to hear your pedantic comments ;) - add handy SPECS_PAGE references wherever useful - comments, cleanup - add me as module author Signed-off-by:

Check the continuity of allocated pages to reduce the BDL size as much as possible so that it can use more than 1MB buffers. Signed-off-by:

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. Signed-off-by:

snd_dma_alloc_pages_fallback() always tries to reduce the size in a half, but it's not good when the given size isn't a power-of-two. Check it first then try to align. Signed-off-by:

- use specs-derived register name enums instead of open-coded numeric values, for better understanding of things - fix naming confusion ("gcr" was _NOT_ the GCR register stuff, but instead the io _base_ which has multiplexed _access_ to GCR config space, at _sub_ registers 0x08 and 0x0c) - add FIXME comments about a race condition and MPU401 features Signed-off-by: -

With the restructering of the indy button handling the old OSS HAL2 driver got broken. Since there is a new ALSA driver for HAL2, the experimental OSS driver is obsolete and will be removed by this patch. Signed-off-by:

When bdl_pos_adj=0 is given, disable the position-check and the delayed period update mechanism. Usually bdl_pos_adj=0 is set only for the debugging purpose on really broken hardwares. It's better to disable the extra complexity in such a case. Signed-off-by:

The dummy driver uses runtime->private_free but still frees its pcm structures on error paths. This is esoteric because the error paths in question are unreachable. Thus the bug is only a problem when someone copies this code into other drivers. Signed-off-by:

The SPDIF output is toggled at each time any SPDIF status bits are changed because of the known problems on some codecs. But, this also results in loosing the sync, and the problem is more obvious on HDMI output over SPDIF. Since the toggle is necessary only for some codecs, we should check whether this workaround is needed and skip if unnecessary. Signed-off-by:
