2024-04-28ALSA: emu10k1: move the whole GPIO event handling to the workqueueOswald Buddenhagen1-2/+1
The actual event processing was already done by workqueue items. We can move the event dispatching there as well, rather than doing it already in the interrupt handler callback. This change has a rather profound "side effect" on the reliability of the FPGA programming: once we enter programming mode, we must not issue any snd_emu1010_fpga_{read,write}() calls until we're done, as these would badly mess up the programming protocol. But exactly that would happen when trying to program the dock, as that triggers GPIO interrupts as a side effect. This is mitigated by deferring the actual interrupt handling, as workqueue items are not re-entrant. To avoid scheduling the dispatcher on non-events, we now explicitly ignore GPIO IRQs triggered by "uninteresting" pins, which happens a lot as a side effect of calling snd_emu1010_fpga_{read,write}().

2023-07-17ALSA: emu10k1: track loss of external clock on E-MU cardsOswald Buddenhagen1-0/+1
85;95;0c This uses IRQs to track spontaneous changes to the word clock source register. FWIW, that this can happen in the first place is the reason why it is futile to lock the clock source mixer setting while the device is open - we can't consistently control the rate anyway. Though arguably, we should reset any open streams when that happens, as they become corrupted anyway.

This patch converts the resource management in PCI emu10k1 driver with devres as a clean up. Each manual resource management is converted with the corresponding devres helper, the page allocations are done with the devres helper, and the card object release is managed now via card->private_free instead of a lowlevel snd_device.

2017-06-12ALSA: seq: Allow the modular sequencer registrationTakashi Iwai1-1/+1
Many drivers bind the sequencer stuff in off-load by another driver module, so that it's loaded only on demand. In the current code, this mechanism doesn't work when the driver is built-in while the sequencer is module. We check with IS_REACHABLE() and enable only when the sequencer is in the same level of build. However, this is basically a overshoot. The binder code (snd-seq-device) is an individual module from the sequencer core (snd-seq), and we just have to make the former a built-in while keeping the latter a module for allowing the scenario like the above. This patch achieves that by rewriting Kconfig slightly. Now, a driver that provides the manual sequencer device binding should select CONFIG_SND_SEQ_DEVICE in a way as select SND_SEQ_DEVICE if SND_SEQUENCER != n Note that the "!=n" is needed here to avoid the influence of the sequencer core is module while the driver is built-in. Also, since rawmidi.o may be linked with snd_seq_device.o when built-in, we have to shuffle the code to make the linker happy. (the kernel linker isn't smart enough yet to handle such a case.) That is, snd_seq_device.c is moved to sound/core from sound/core/seq, as well as Makefile. Last but not least, the patch replaces the code using IS_REACHABLE() with IS_ENABLED(), since now the condition meets always when enabled. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2015-04-27ALSA: emu10k1: Fix card shortname string buffer overflowTakashi Iwai1-2/+4
Some models provide too long string for the shortname that has 32bytes including the terminator, and it results in a non-terminated string exposed to the user-space. This isn't too critical, though, as the string is stopped at the succeeding longname string. This patch fixes such entries by dropping "SB" prefix (it's enough to fit within 32 bytes, so far). Meanwhile, it also changes strcpy() with strlcpy() to make sure that this kind of problem won't happen in future, too. Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

CA0106 driver,EMU10K1/EMU10K2 driver A thread appeared on the LKML. This patch implements the fix. Question: in sysfs, /sys/bus/*/drivers lists the driver names, with their exported .name (eg. '.name = 'EMU10K1_Audigy'' in the module code, from now on 'driver name'). In /sys/modules, the kernel modules are listed with their module name, eg. snd_emu10k1. However, it seems to me that in sysfs, there is no way in particular to tell, which module has which .name. That is, that snd_emu10k1 is EMU10K1_Audigy and vice versa. I wonder whether it wouldn't be possible to add a symlink to the particular module from the driver, and/or from the module to the driver, so the list of devices handled by the module and the module name would be accessible. This way, I would know which driver name corresponds to which module name and vice versa. Answer: For PCI drivers, just add the line: .owner = THIS_MODULE, to their struct pci_driver definition and you will get the symlink created for you.
