gack. Someone is requesting 128k of memory with GFP_ATOMIC. It fell afoul of the reduced memory reserves. It deserved to.

Could you please add this patch, and make sure that you have set CONFIG_KALLSYMS=y? This will find the culprit.

Thanks.

Could you please add this patch, and make sure that you have set CONFIG_KALLSYMS=y? This will find the culprit.

Nope, playing mp3s from a harddrive. I can reproduce it by doing some IO or compiling something and then switching back and forth through workspaces really fast at the same time..

Ah. Well could you please add the second patch? That'll find the source.

It didn't apply ontop of the one that you sent earlier so I compiled with only the second one..

I got this while applying the second one:

OK, thanks. The audio driver is trying to allocate a large DMA buffer and just falls back to a smaller size if it fails.

And dma_alloc_coherent() forces GFP_ATOMIC, which is quite broken of it.

Let's leave this one as-is. It'll be OK when all the debug code is pulled out.

gack. Someone is requesting 128k of memory with GFP_ATOMIC. It fell afoul of the reduced memory reserves. It deserved to.

ISA sound I/O. And yes it really does want the 128K if it can get it on a slower box. It will try 128/64/32/.. so it gets less if there isnt any DMA RAM around. All the sound works this way because few bits of sound hardware, even in the PCI world, support scatter gather.

If the VM can't deal with it - we need to fix the VM. All these allocations are blocking and can wait a long time.

Please direct any complaints to the hardware vendors.

And doesn't support scatter gather either so does the same thing.

It'll tend to usually work because GFP_KERNEL allocations prefer to not dip into the DMA region.

All these allocations are blocking and can wait a long time.

But it's not! dma_alloc_coherent() is using GFP_ATOMIC|__GFP_DMA.

Now, if we can fix the caller to use

	__GFP_WAIT | __GFP_IO | __GFP_HIGHIO | __GFP_FS | __GFP_DMA

then that at least will allow page reclaim.

Then we can remove this restriction in __alloc_pages():

        /*
         * Don't let big-order allocations loop.  Yield for kswapd, try again.
         */
        if (order <= 3) {
                yield();
                goto rebalance;
        }

and all will be well.

dma_alloc_coherent() should be fixed to take a gfp_mask, and callers should be updated.

As for permitting direct page reclaim for higher-order allocations: I just don't know - it's from before my time. Perhaps the VM will livelock.
