In the PCM read/write loop, the driver calls snd_pcm_update_hw_ptr() at each time at the beginning of the loop. Russell King reported that this hogs CPU significantly. The current code assumes that the pointer callback is very fast and cheap, also not too much fine grained. It's not true in all cases. When the pointer advances short samples while the read/write copy has been performed, the driver updates the hw_ptr and gets avail > 0 again. Then it tries to read/write these small chunks. This repeats until the avail really gets to zero. For avoiding this situation, a simple workaround is to call snd_pcm_update_hw_ptr() only once at starting the loop, assuming that the read/write copy is performed fast enough. If the available count becomes short, it goes to snd_pcm_wait_avail() anyway, and this processes right.

GFP_ATOMIC is used in snd_pcm_link() just because the kmalloc is called inside a lock. Since this function isn't too critical for speed and is rarely called in practice, better to allocate the chunk at first before spinlock and free it in error paths, so that GFP_KERNEL can be used.

For files that are actively using linux/device.h, make sure that they call it out. This will allow us to clean up some of the implicit uses of linux/device.h within include/* without introducing build regressions. Yes, this was created by "cheating" -- i.e. the headers were cleaned up, and then the fallout was found and fixed, and then the two commits were reordered. This ensures we don't introduce build regressions into the git history. Signed-off-by: NPaul Gortmaker <paul.gortmaker@windriver.com>

由 Liam Girdwood 提交于
The new ASoC dynamic PCM core needs to create PCMs and substreams that are for use by internal ASoC drivers only and not visible to userspace for direct IO. These new PCMs are similar to regular PCMs expect they have no device nodes or procfs entries. The ASoC component drivers use them in exactly the same way as regular PCMs for PCM and DAI operations. The intention is that a dynamic PCM based driver will register both regular PCMs and internal PCMs. The regular PCMs will be used for all IO with userspace however the internal PCMs will be used by the driver to route digital audio through numerous back end DAI links (with potentially a DSP providing different hw_params, DAI formats based on the regular front end PCM params) to devices like CODECs, MODEMs, Bluetooth, FM, DMICs, etc This patch adds a new snd_pcm_new_internal() API call to create the internal PCM without device nodes or procfs. It also adds adds a new internal flag to snd_pcm. [fixed minor coding-style issues by tiwai] Signed-off-by: NLiam Girdwood <lrg@ti.com> Signed-off-by: NTakashi Iwai <tiwai@suse.de>

This is mostly a static checker fix more than anything else. We're copying from a 64 char buffer into a 44 char buffer. The 64 character buffer is str[] in snd_mixer_oss_build_test_all(). The call tree is: snd_mixer_oss_build_test_all() -> snd_mixer_oss_build_test() -> snd_mixer_oss_build_test(). We never actually do fill str[] buffer all the way to 64 characters. The longest string is: sprintf(str, "%s Playback Switch", ptr->name); ptr->name is a 32 character buffer so 32 plus 16 characters for " Playback Switch" still puts us over the 44 limit from "id.name". Most likely ptr->name never gets filled to the limit, but we can't really change the size of that buffer so lets just use strlcpy() here and be safe.
