2023-04-23ALSA: emu10k1: fixup DSP definesOswald Buddenhagen
Firstly, fix the distribution between public and private headers. Otherwise, some of the already public macros wouldn't actually work, and the SNDRV_EMU10K1_IOCTL_DBG_READ result for Audigy would be useless. Secondly, add condition code registers for Audigy. These are just aliases for selected constant registers, and thus are generation- specific. At least A_CC_REG_ZERO is actually correct ... Finally, shuffle around some defines to more logical places while at it, and fix up some more comments.

2023-04-23ALSA: emu10k1: remove some bogus definesOswald Buddenhagen
Firstly, remove the FXWC_* defines - the comment on FXWC implies that the relevant defines are the (A_)EXTOUT_* ones. It's unclear where this came from - it was in the initial ALSA import, but neither the driver from Creative nor kX-project have these defines. Secondly, remove A_HR, which made plain no sense (was unused, and clashed with FXRT). Amends commit cbb7d8f9b7b ("emu10k1: Update registers defines for the Audigy 2/emu10k2.5").

2023-04-22ALSA: emu10k1: fix snd_emu1010_fpga_read() input masking for rev2 cardsOswald Buddenhagen
Unlike the Alice2 chips used on 1st generation E-MU cards, the Tina/Tina2 chips used on the 2nd gen cards have only six GPIN pins, which means that we need to use a smaller mask. Failure to do so would falsify the read data if the FPGA tried to raise an IRQ right at that moment. This wasn't a problem so far, as we didn't actually enable FPGA IRQs, but that's going to change soon.

2023-04-22ALSA: emu10k1: fix access to Audigy GPIO portOswald Buddenhagen
As the register definition clearly states, this is a 16-bit register, yet we did all accesses as 32-bit. The writes in particular would have the potential to clear the TIMER register (depending on how the bus/card actually handles the too long writes). This commit also introduces a separate define A_GPIO which aliases A_IOCFG, which better reflects the distinct usage on E-MU cards. This is done in the same commit to keep the churn down, as we're touching all involved lines anyway.

2023-04-22ALSA: emu10k1: clean up P16V part somewhatOswald Buddenhagen
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.

extin_mask and extout_mask are used only by the SbLive! microcode, so they have no effect on Audigy. Eliminate fxbus_mask entirely, as it wasn't actually used for anything. As a drive-by, remove the pointless pad1 field from struct snd_emu10k1_fx8010 - it is not visible to user space, so it has no binary compatibility constraints.

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.

2018-04-16ALSA: emu10k1: Reduce GFP_ATOMIC allocationTakashi Iwai
The emu10k1 fx8010 code allocates each irq resource dynamically and links to the list at PCM trigger callback. Due to the nature of trigger callback, the allocation is done with GFP_ATOMIC, hence it may fail more often. Moreover, the irq resource isn't big at all, and using the kmalloc for this won't save many bytes, either. This patch removes the dynamic allocation and embeds the irq resource into struct snd_emu10k1_fx8010_pcm.irq field instead of keeping a pointer. As a result, it simplifies the code and removes the unnecessary GFP_ATOMIC usage. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2018-02-14ALSA: emu10k1: add a IOMMU workaroundMaciej S. Szmigiero
The Audigy 2 CA0102 chip (but most likely others from the emu10k1 family, too) has a problem that from time to time it likes to do few DMA reads a bit beyond its normal allocation and gets very confused if these reads get blocked by a IOMMU. For the first (reserved) page this happens multiple times at every playback, for various synth pages it happens randomly, rarely for PCM playback buffers and the page table memory itself. All these reads seem to follow a similar pattern, observed read offsets beyond the allocation end were 0x00, 0x40, 0x80 and 0xc0 (PCI cache line multiples), so it looks like the device tries to accesses up to 256 extra bytes. As a workaround let's widen these DMA allocations by an extra page if we detect that the device is behind a non-passthrough IOMMU (the DMA memory should be relatively plenty on IOMMU systems).

2018-02-14ALSA: emu10k1: remove reserved_pageMaciej S. Szmigiero
The emu10k1-family chips need the first page (index 0) reserved in their page tables for some reason (every emu10k1 driver I've checked does this without much of an explanation). Using the first page for normal samples results in a broken playback. However, we already have a dummy page allocated - so called "silent page" and, in fact, had always been setting it as the first page in the chip page table because an initialization of every entry of the page table to point to a silent page happens after and overwrites the reserved_page allocation. So the only thing remaining to remove the reserved_page allocation is a trivial change to the page allocation logic to ignore the first page entry and start its allocations from the second entry (index 1).

2016-11-15ALSA: emu10k1: Use workqueue instead of kthread for emu1010 fw pollingTakashi Iwai
This patch is a cleanup of EMU1010 dock probing code in emu10k1 driver to use work instead of kthread in a loop. The work is lighter and easier to control than kthread, in general. Instead of a loop with the explicit sleep, we do simply delayed-schedule the work. At suspend/resume callbacks, the work is canceled and restarted, respectively.
