[Bug 183456] Re: Trying to load a sf2 file with asfxload returns "sfxload: no memory left"
I tried the patch and it works great (though I can't seem to get the other patch to work to increase the limit to 2gb for soundfonts), it's just really inconvenient to recompile the kernel and now after initially compiling it, it doesn't want to compile again and complains about a signing key.

Look, what else to say? The patch is there, it has been confirmed to work, and it still works here. See #10 on this list.

It's 2018 and this bug is still here; running 4GB ram 64bit + Live 5.1 and the effect is just like here. I have an onboard builtin "soundcard" but the sound it produces is way flatter and less full than the one I hear via the SB Live; may be just a case of config; maybe there is a difference in the hardware and that's all that can be done about it. I rather utilize the SB Live anyway; loading soundfonts up to 16MB works fine (fonts like Aspirin I find to be most interesting so far); I do want to load at least Fluid fonts though to at least mimic the basic sound I can obtain via software.

I have tried the small 2L change by Thomas Richter and it works fine, no negative side effects so far. Apparently, the 4GB barrier was a bit of an arbitrary value anyway, you can read about that here: https://lwn.net/Articles/152337/ I found the memmap=2048M\\$6144M workaround proposed on http://www .alsa-project.org/main/index.php/Matrix:Module-emu10k1 rather ridiculous, even if it doesn't require patching. With Thomas' simple fix making it rather easy for us to solve our problem, let's hope the kernel devs won't change the MAX_DMA32_PFN code too soon so that it doesn't apply anymore. Because I do not believe they will care about 1 or 2 pieces of hardware that will eventually fade into history on all new non-PCI systems... Still, isn't it quite an achievement that we can still use a soundcard that has been released ages ago?

My patch will not compile and fails with: include/linux/mmzone.h:335:2: error: #error ZONES_SHIFT -- too many zones configured adjust calculation Looking into this, I found in include/linux/gfp.h: * GFP_ZONE_TABLE is a word size bitstring that is used for looking up the * zone to use given the lowest 4 bits of gfp_t. Entries are ZONE_SHIFT long * and there are 16 of them to cover all possible combinations of * __GFP_DMA, __GFP_DMA32, __GFP_MOVABLE and __GFP_HIGHMEM.

Another approach... I set out to target the 2GB limit workaround to only affect the emu10k1, and at the same time make some placeholders for code to create an additional 31bit DMA region. Then I spent hours trying to set the right kernel configuration for my system and gave up.

[Bug 183456] Re: Trying to load a sf2 file with asfxload returns sfxload: no memory left
An alternative solution to patching the kernel is to add a line to the bootloader excluding all but 2GB of RAM whenever you're going to be using MIDI. I got this idea from reading the forum at http://ubuntuforums.org/showthread.php?t=1340309 and have confirmed that it works. I have 8GB of RAM and a SoundBlaster Audigy 2 ZS card. I'm using the version of GRUB that comes with Ubuntu 12.04. I pressed e at the boot loader screen to add custom options and, after the word splash, added the line memmap=2048M\\$6144M with no quotes. I've confirmed that I'm able to load a SoundFont of in excess of 100MB with no problem whereas previously I got the error message. MIDIs play fine with the large SoundFont in Rosegarden. This is a kludge, but at least it's not modifying a system-wide kernel variable. Note that when you boot up with that option, your system will of course think that it only has 2GB of RAM.

ohhh... this is a bit deeper than my knowledge of the linux kernel but i'm starting to get the picture. perhaps there is another way to get this done, without proposing major changes to the kernel. is it possible to add code to either the emu10k1 module or asfxload to buffer large soundfonts? The goal being to load large soundfonts without breaking memory allocation by limiting how much the emu10k1 can load into memory and caching the rest to another memory location (faster than to disk). if soundfont data could be loaded and unloaded on-the-fly, as needed, it may be possible to use large soundfonts without such a large DMA. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/183456 Title: Trying to load a sf2 file with asfxload returns sfxload: no memory left To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/awesfx/+bug/183456/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sorry, but I don't waste my time there. I believe I reported this problem already several years ago, and it was basically ignored or the patch wasn't accepted. To some degree, I understand this because it doesn't address the *real* problem (which is the unflexibility of the kernel memory allocation mechanism), but then again, I'm not knowledgable enough to provide a fix for that (namely a re-design of the kernel allocation).

Raymond I didn't understand what your post was about at first. After looking into it, this does seem like the single line of code to change. From OSS (via a page so outdated it exists only in google cache): linux/sound/oss/emu10k1/main.c ... 121 /* the emu10k1 _seems_ to only supports 29 bit (512MiB) bit bus master */ 122 #define EMU10K1_DMA_MASK0x1fff /* DMA buffer mask for pci_alloc_consist */ ... Perhaps the OSS developers were right. To do: 1. Patch a current kernel to give a 29bit DMA mask to the emu10k1 module 2. Test emu10k1 card and awesfx against the patched kernel. 3. If successful, push the patch upstream and into the kernel. This change sounds a lot better to me as it should not affect any other hardware.

[Bug 183456] Re: Trying to load a sf2 file with asfxload returns sfxload: no memory left
The problem is not which DMA mask the kernel assigns to the module. The problem is what the kernel does if the memory to be accessed via the emu10k1 DMA is *not* in range of the DMA mask. The emu10k1 reaches the 30 bit address space just fine, as my all-day experience tells me. What the kernel driver does is in principle correct - it goes for the 24 bit DMA space (the lowest 16 MB or so). This address range would be reachable by the emu10k1. The problem is just that this memory region is too small to hold a sound font, and then simply fails. The granularity offered by the kernel is too small - there is either the 64 bit space (which is not reachable by PCI anyhow), then the 4GB space, still too large for the emu10k1, and then the 16MB ISA space, which is reachable, but too small to be useful. Thus, the kernel memory architecture is too unflexible. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/183456 Title: Trying to load a sf2 file with asfxload returns sfxload: no memory left To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/awesfx/+bug/183456/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It most certainly does. However: Current kernel hackers seem to prefer to work around the situation by reverting to a timidity based software emulation of midi. It is not exactly the same as the emu10k1 midi, and - if you ask me - is of lower quality. Thus, at least kernel developers have a reason to say go away, we don't need to care. Second, fixing the issue requires a deeper modification of the kernel, namely providing a more flexible memory allocation, or more DMA zones. The above hack does the trick, and it doesn't affect stability, but it changes the DMA zones of course - and just doing that for a single card might not be a good argument. Instead, the kernel should provide means to allocate memory with more flexible constraints than just the DMA zones that exist now. However, the issue doesn't seem to be pressing enough to move forward - at least this is my impression.

Thomas, thank you for your clear description of the issue.
Given that the problem is memory beyond the 2GB barrier, something I
wanted to try was mmap()'s MAP_32BIT flag. You can sort-of do a malloc()
by making an anonymous mapping, and so I hacked up safe_malloc() and
safe_free() (in awelib/malloc.c) accordingly. My patch against the
awesfx-0.5.1a source (current Ubuntu version) is attached.
The addresses returned are consistently 0x4[0-9a-f]{7}, yet I continue
seeing the no memory left error. Do you think there is something in
this approach that may allow a solution that doesn't require kernel
modification, or are we still at the mercy of the kernel's memory
allocation policy?
Not really, at least not according to my understanding of the situation.
Look,
obviously the kernel has to copy over the sound font from user memory to
kernel
memory anyhow - simply because the user memory where awelib initially
loads the sound font into is released by the Os as soon as the program
is unloaded.
Thus, any user space tools cannot, by construction, control where the
wavetable
will go. It is the kernel that runs out of memory when trying to
allocate persistent
kernel memory for the sound font, not the user space tools.
Thus, this really requires a modification of the kernel emu10k1 driver,
unfortunately.

Thomas

Given that the problem is memory beyond the 2GB barrier, something I
wanted to try was mmap()'s MAP_32BIT flag. You can sort-of do a malloc()
by making an anonymous mapping, and so I hacked up safe_malloc() and
safe_free() (in awelib/malloc.c) accordingly. My patch against the
awesfx-0.5.1a source (current Ubuntu version) is attached.
The addresses returned are consistently 0x4[0-9a-f]{7}, yet I continue
seeing the no memory left error. Do you think there is something in
this approach that may allow a solution that doesn't require kernel
modification, or are we still at the mercy of the kernel's memory
allocation policy?

Raymond wrote: you have to change max_buffer_size if you want to load a larger soundfont as default value is 128Mb The issue is not with the size of the soundfont. The issue is that the kernel tries to put them into the 16MB ISA DMA zone, being short of memory below 2GB. Here's the technical explanation: The kernel first tries to allocate 32bit memory for the soundfont. It then checks whether the allocated memory is above the 2GB barrier. Having a hardware bug in the emu10k1, the hardware can only support DMA from the lowest 2GB of memory because it simply ignores bit 31 of the address. The memory allocator then comes back with memory which is, due to the memory allocation policy, *above* the 2GB barrier whenever more than 2GB is installed in the system. This, of course, won't work, and the kernel/emu10k1 driver notices this, releases the memory and then tries next to take the memory from the 16MB ISA zone. Of course, there isn't enough memory available to load the soundfont, which then fails. There is a fix, namely shorten the kernel 32bit DMA zone to 2GB, namely replace in arch/x86/include/asm.h the following line: #define MAX_DMA32_PFN ((2UL * 1024 * 1024 * 1024) PAGE_SHIFT) here the 4UL has been replaced by a 2UL, which does the indicated reduction of the 32bit DMA memory, and brings the emu10k1 back to work. It has no other drawbacks, i.e. the machine is working with correspondingly patched kernels for over a year by now. The true fix would be to make the memory allocation of the kernel a bit more flexible than it is now.

[Bug 183456] Re: Trying to load a sf2 file with asfxload returns sfxload: no memory left
I don't quite understand your comment. The above fix applies to the AMD64 platform. There is no such thing as a 32bit DMA zone on x86, but still the kernel might want to allocate physical addresses for the buffer memory beyond the 2GB barrier (bit 31 set), thus it is prone to failure in any system equipped with more than 2GB of RAM. Sure enough, a *small* soundfont could be loaded if enough memory is available in the 16MB DMA zone, but this depends on a lot of other factors (as, for example, which other devices require DMA memory).

But what if the driver just makes repeated requests until it gets the

Subject: [Bug 183456] Re: Trying to load a sf2 file with asfxload returns
sfxload: no memory left
The problem with this goes a bit deeper. The reason for all this trouble
is that the emu10k1 chipset requires DMA from main memory to pick up the
samples, and - unfortunately - the DMA engine of the chip is broken.
Instead of using the full range of 32 bit DMA available on the PCI bus,
it only addresses 31 bit of the 32 available.
To work around this problem, the kernel driver first allocates a page of
main memory, signaling the 32 bit DMA memory zone, i.e. indicating the
kernel that it requires 32 bit memory in a 64 bit memory system.
However, if now the returned memory happens to have bit 31 set, the
emu10k1 wouldn't be able to address the memory. Then, the driver
releases the memory again, and requests memory in the 16MB ISA memory
region, which is clearly suitable for the chip. Unfortunately, this type
of memory runs out easily, and then the chip is left with no usable
memory at all.
The problem is that the kernel isn't smart enough to provide memory that
is just right for the chip, i.e. the DMA zone allocation isn't quite
sufficient for this situation. There seem to be plans on the LKLM to
address this, but it's unclear how long this will take - after all, the
complete kernel page allocator must be re-structured to fix this.
How to work around? Oh well, the easiest is to lower the 32bit PCI DMA
zone from 4G to 2G. This means that some non-broken devices will require
to allocate pages in the 2GB region (bad enough), and the memory layout
might be sub-optimal for those devices, but at least the hack will work.
For that, download the kernel, and edit arch/x86/include/asm/dma.h,
locate the line:
#define MAX_DMA32_PFN ((4UL * 1024 * 1024 * 1024) PAGE_SHIFT)
and replace the 4UL by a 2UL, which will shrink the 32-bit DMA zone by
half. This is not a permanent solution - it's an ugly bad hack that is
good enough for me. There is no kernel boot option to do this AFAIK.
So long, happy hacking,
Thomas

[Bug 183456] Re: Trying to load a sf2 file with asfxload returns sfxload: no memory left
Well, simply re-allocating doesn't help since this will get it exactly the same memory as before - so it had to fetch memory over and over again until it succeeds, and then had to release all the unusable memory again. Possible, but would require it to fetch at most 2GB of memory (urgh!) just for nothing, plus the overhead, and the time needed to do the allocation and to loop for all that to happen. Remember, these are 2G/4K = 524288 allocations to be done! I'd say the problem should really fixed at its origin. For first, the emu10k1 is broken - too bad, a rather good card otherwise - I've two of them. And if replacing that is not an option (which it isn't for me), I'd say that the kernel should really provide better mechanisms to allocate the right memory.

[Bug 183456] Re: Trying to load a sf2 file with asfxload returns sfxload: no memory left
Can't anyone pick this up? Please? I have had this problem for years now, ever since I upped my RAM. I would love to use my emu10k1 synth chip again since it is less laggy than any software synth. I was told that this problem is due to the EMU10k1 being unable to address more than 2G of memory. That is why the emu10k1 driver can load a soundfont when the system has 2G, but not when it has more. I had 4G and now 6G and so I have this issue. It appears that the solution would be to modify the emu10k1 driver so it allocates its soundfont cache within the lowest 2G of RAM. I believe the allocation is done in emu10k1_main.c, and it is currently done by vmalloc. I have read of references to a DMA32 flag that is often used to fix similar problems with other old sound cards.
