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.

2015-04-29ALSA: emu10k1: Emu10k2 32 bit DMA modePeter Zubaj
Looks like audigy emu10k2 (probably emu10k1 - sb live too) support two modes for DMA. Second mode is useful for 64 bit os with more then 2 GB of ram (fixes problems with big soundfont loading) 1) 32MB from 2 GB address space using 8192 pages (used now as default) 2) 16MB from 4 GB address space using 4096 pages Mode is set using HCFG_EXPANDED_MEM flag in HCFG register. Also format of emu10k2 page table is then different.

With some hardware combinations, the PCM interrupts are acknowledged before the period boundary from the emu10k1 chip. The midlevel PCM code gets confused and the playback stream is interrupted. It seems that the interrupt processing shift by 2 samples is enough to fix this issue. This default value does not harm other, non-affected hardware.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
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.
