* ALSA: emu10k1: clean up driver status commentsOswald Buddenhagen2023-07-171-6/+0
| | | | | | | | | | | | | | 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 Version information is chronically outdated, and not really useful in a git world anyway, so remove it as well. Also remove duplicated (and outdated, of course) status section from p16v.h (the one in p16v.c is in better shape).

* ALSA: emu10k1: fix handling of half-loop interruptsOswald Buddenhagen2023-05-181-1/+3
| | | | | | | | | | | | We'd try to iterate the voices twice without resetting the pointer. This went unnoticed, because the code isn't actually in use.

* ALSA: emu10k1: simplify interrupt handler, part 2Oswald Buddenhagen2023-05-181-18/+0
| | | | | | | | | | | | Remove weird INTE_* clearing code. The bits were a subset of the actually handled interrupts, which kind of contradicted the stated purpose. I suppose it would make sense to complete the set and negate it, but interrupts being enabled out of the blue is neither something that happens a lot, nor should it result in just one error message, IMO.

* ALSA: emu10k1: simplify interrupt handler, part 1Oswald Buddenhagen2023-05-181-2/+1
| | | | | | | | | | | IPR_CHANNELNUMBERMASK cannot be non-zero when IPR_CHANNELLOOP is unset, so join marking them as handled. This logically reverts part of commit f453e20d8a0 ("ALSA update 0.9.3a"), which made the inverse change with no explanation.

* ALSA: emu10k1: clean up P16V part somewhatOswald Buddenhagen2023-04-221-27/+5
| | | | | | | | | | | | | | | | | | | | | | | | Detach it better from the main PCM driver, which it really doesn't have much in common with. In particular, this moves the interrupt handler implementation into p16v.c, and makes it access the substream runtime status more directly, so it doesn't need to abuse structs snd_emu10k1_pcm and snd_emu10k1_voice any more. We don't need private pcm runtime data at all, as the only thing it was used for (except the back-link to the substream) was the `running` flag. So store that directly in runtime->private_data. This somewhat radical strip-down shows that this driver contains some complexity that was never actually utilized. I suppose the right way to fully utilize the hardware in a simple way would be introducing more substreams. This wouldn't require any of the removed code.

| | | | | | | | | | | | 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.

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

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!
