2024-08-08ALSA: emux: Use standard print APITakashi Iwai
Use the standard print API with dev_*() instead of the old house-baked one. It gives better information and allows dynamically control of debug prints. Some functions are changed to receive snd_card object for calling dev_*() functions, too.

2024-04-07ALSA: emux: simplify snd_sf_list.callback handlingOswald Buddenhagen
Both drivers provide both sample_new and sample_free, and it makes no sense to pretend that they could not. In fact, load_data() would already crash if sample_new was null. So remove the remaining null checks. Contrary to that, the emu10k1 driver actually has a null sample_reset, though I'm not convinced that this inconsistency is justified.

2024-04-07ALSA: emux: improve patch ioctl data validationOswald Buddenhagen
In load_data(), make the validation of and skipping over the main info block match that in load_guspatch(). In load_guspatch(), add checking that the specified patch length matches the actually supplied data, like load_data() already did.

2024-04-07ALSA: emux: centralize & improve patch info validationOswald Buddenhagen
This does several closely related things: - Move the code from the drivers into the SoundFont loader, which de-duplicates it. - Sort of explain the weird "recalculate address offset" feature. Note that I don't think it actually makes any sense - the calling user space code should do that. The background is certainly that the source data (the SoundFont format) uses pointers into a single wave block (and the API allows doing the same for on-board ROM), but the API expects the wave data from user space to be pre-chopped into individual patches anyway. - Make sure that the specified offsets actually lie within the supplied wave data. Note that we don't validate ROM offsets, so one can play back anything within the sound card's address space. - In load_guspatch(), don't call the sample_new callback anymore when the patch size is zero, as was already the case in load_data(). The callbacks would instantly return in that case anyway; these checks are now removed.

2024-04-07ALSA: emux: fix init of patch_info.truesize in load_data()Oswald Buddenhagen
The field is explicitly documented to be initialized by the driver (which it actually is). Also, using patch_info.size would be actually wrong for 16-bit data, as one field counts samples, while the other counts bytes. load_guspatch() already did it right.

EMUx synth driver code contains lots of assignments in if condition, which is a bad coding style that may confuse readers and occasionally lead to bugs.

This header file exists only for some hacks to adapt alsa-driver tree. It's useless for building in the kernel. Let's move a few lines in it to sound/core.h and remove it. With this patch, sound/driver.h isn't removed but has just a single compile warning to include it. This should be really killed in future.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
