- Remove the "log-like" parts, following the same logic as the previous commit - Unify format - Add missing major contributors, including myself - Sort entries in order of first contribution (Creative comes last for optical reasons; they don't appear to have directly contributed anyway) Signed-off-by: Oswald Buddenhagen <oswald.buddenhagen@gmx.de> Link: https://lore.kernel.org/r/20230715160839.326978-2-oswald.buddenhagen@gmx.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2023-07-17ALSA: emu10k1: clean up driver status commentsOswald Buddenhagen
Empty BUGS and TODO sections don't really help anyone, so remove them. Version information is chronically outdated, and not really useful in a git world anyway, so remove it as well. Also remove duplicated (and outdated, of course) status section from p16v.h (the one in p16v.c is in better shape).

2023-07-13ALSA: emu10k1: remove superfluous IRQ enable state savingOswald Buddenhagen
The mixer, PCM prepare, MIDI, synth driver, and procfs callbacks are all always invoked with IRQs enabled, so there is no point in saving the state. snd_emu1010_load_firmware_entry() is called from emu1010_firmware_work() and snd_emu10k1_emu1010_init(); the latter from snd_emu10k1_create() and snd_emu10k1_resume(), all of which have IRQs enabled. The voice and memory functions are called from mixed contexts, so they keep the state saving. The low-level functions all keep the state saving, because it's not feasible to keep track of what is called where.

2023-06-13ALSA: emu10k1: actually show some S/PDIF status in /proc for E-MU cardsOswald Buddenhagen
The file is called spdif-in, but we abused it to show only sample rates from various sources. Rectify it as far as possible (the FPGA doesn't give us a lot of information).

2023-06-13ALSA: emu10k1: query rate of external clock sources on E-MU cardsOswald Buddenhagen
The value isn't used yet; the subsequent commits will do that. This ignores the existence of rates above 48 kHz, which is fine, as the hardware will just switch to the fallback clock source when fed with a rate which is incompatible with the base clock multiplier, which currently is always x1. The sample rate display in /proc spdif-in is adjusted to reflect our understanding of the input rates. This is tested only with an 0404b card without sync card, so there is a lot of room for improvement.

2023-06-05ALSA: emu10k1: vastly improve usefulness of info in /procOswald Buddenhagen
- Include the FX bus map, without which the already present send routing info would require looking up the documentation. - Include the physical I/O channels as known to the driver - Make the multi-channel capture map actually name the mapped input channels rather than "FXBUS" (Audigy) or even "???" (SbLive) - The latter two are omitted for E-MU cards, as their physical I/O is routed through the FPGA - While at it, make the "Card" field somewhat more useful This includes de-duplicating the label tables between emuproc and emufx, updating/improving the FX bus label table, and making the SB Live! 5.1 multi-track capture channel mapping hack data-driven.

2023-06-05ALSA: emu10k1: make E-MU FPGA register dump in /proc more usefulOswald Buddenhagen

2023-06-05ALSA: emu10k1: include FX send amounts in /proc outputOswald Buddenhagen
It seems to make little sense to include the FX send routing, but not the amounts. This also simplifies the code somewhat, and lines up the output.

2023-06-05ALSA: emu10k1: fix writing 1st pointer-offset register set through /procOswald Buddenhagen
The limits were appropriate only for the 2nd set. FWIW, the channel count 4 for the 2nd set is suspicious as well - at least P17V_PLAYBACK_FIFO_PTR actually has 8 channels, and comments on HCFG2 hint at that as well. But all bitmasks are documented only for 4 channels. Anyway, rectifying that is out of scope for this patch.

2023-06-05ALSA: emu10k1: hide absent 2nd pointer-offset register set from /procOswald Buddenhagen
The 2nd register set belongs to the P16V chip (or embedded P17V module), so there is nothing to show when no such part is present. Gen2 E-MU cards have a P17V, but it's entirely unused, so we hide it there as well.

2023-05-20ALSA: emu10k1: revamp playback voice allocatorOswald Buddenhagen
Instead of separate voices, we now allocate non-interleaved channels, which may in turn contain two interleaved voices each. The higher-level code keeps only one pointer per channel. The channels are not allocated in one block any more, as there is no reason to do that. As a consequence of that, and because it is cleaner regardless, we now let the allocator store these pointers at a specified location, rather than returning only the first one and having the calling code deduce the remaining ones.

2023-05-18ALSA: emu10k1: make freeing untouched playback voices cheapOswald Buddenhagen
This allows us to drop the code that tries to preserve already allocated voices upon repeated hw_param callback invocations. Getting it right for multi-channel voices would otherwise get a bit hairy.

2023-05-17ALSA: emu10k1: add explicit support for E-MU 0404Oswald Buddenhagen
Unlike the other models, this is actually a distinct card, rather than an E-MU 1010 with different "dongles". It is stereo only, and supports no ADAT (there is no trace of ADAT in the manual, switching the output mode to ADAT has no effect, and switching the input mode to ADAT just breaks input (presumably ... my only ADAT source is the card's output)).

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!
