We're running 64-bit Xex 4.1.1 and 32-bit Linux 3.0.4 Dom0 (Linux 3.1 shows the same symptom.)

Several PCI drivers are unable to use DMA. Most fallback to using PIO but in two instances the network drivers (e1000 and pcinet32) abort. The same kernel running on the same hardware without Xen works fine.

Digging through the code, in swiotlb-xen.c I find "DMA_BIT_MASK(32)" (0x00000000ffffffff) compared to "xen_virt_to_bus(xen_io_tlb_end - 1)" which resolves to 0x1,20fd,feff. Since the address is larger than the mask, DMA is declared as unsupportable.

In talking with others I hear Linux handles this situation with bounce buffers. Is there a config setting I've missed to enable that for Xen? (Config file attached)


Relevant slice of source callback list:
xen_swiotlb_dma_supported (drivers/xen/swiotlb-xen.c: line 591)
dma_supported             (arch/x86/kernel/pci-dma.c: line 199)
dma_set_mask              (arch/x86/kernel/pci-dma.c: line 59)
e1000_probe               (drivers/net/e1000/e1000_main.c: line 986)


Relevant patches:

https://lkml.org/lkml/2011/9/1/100, "[PATCH v2] xen: x86_32: do not enable iterrupts when returning from exception in interrupt context"

http://xen.1045712.n5.nabble.com/PATCH-mm-sync-vmalloc-address-space-page-tables-in-alloc-vm-area-td4757995.html "[PATCH] mm: sync vmalloc address space page tables in alloc_vm_area()" (this patch was reverted for 3.1 but this is 3.0.4) and

an additional 2048 NR_IRQS to support (as I understand it) all the virtual devices we might support with 50 guests.

Not so relevant patches in md, nbd and loop.

Hm, 32-bit. Did it work if the Dom0 was 64-bit?

xen_io_tlb_end resolved to 120fdfeff? That is a definite bug. Can you
attach you full bootup serial log with 'debug loglevel=8' parameters on
the Linux line please?

The Xen SWIOTLB is by default enabled, so it is on, but the
xen_virt_to_bus(xen_io_tlb_end - 1) _MUST_ never be above 4GB. In your
case it is, which is bad. It is rather surprising as I had not seen this
ever happen.

We're having trouble getting a serial log. Are there other ways to capture the information you need?

Attached is a dmesg with 'debug loglevel 8' set on the kernel line... actually, with  

   #define DEFAULT_MESSAGE_LOGLEVEL 8

set near the top of printk.c as well, since I wasn't seeing any difference in the log files with loglevel set to 8.

I'm not seeing any difference in symptom or log.

Also, where is the log telling you that it's allocated above 4GB?

Is it the translation that's in error?

Modeled after the translation in xen_swiotlb_dma_supported that's used for the problematic comparison, I added "the same" translation to swiotlb_print. I don't understand the results as dend - dstart is vastly larger that pend - pstart.



 void swiotlb_print_info(void)
 {
         unsigned long bytes = io_tlb_nslabs << IO_TLB_SHIFT;
         phys_addr_t pstart, pend;
+        dma_addr_t dstart, dend;
 
+        pstart = virt_to_phys(io_tlb_start);
+        pend = virt_to_phys(io_tlb_end);
+
         dstart = phys_to_machine(XPADDR(pstart)).maddr;
         dend   = phys_to_machine(XPADDR(pend)). maddr;
 
         printk(KERN_INFO "Placing %luMB software IO TLB between %p - %p\n",
                bytes >> 20, io_tlb_start, io_tlb_end);
         printk(KERN_INFO "software IO TLB at phys %#llx - %#llx\n",
                (unsigned long long)pstart,
                 (unsigned long long)pend);
+        printk(KERN_INFO "software IO TLB at bus %#llx - %#llx\n",
+               (unsigned long long)dstart,
+                (unsigned long long)dend);
 }

Yields:

You might want to instrument the xen_swiotlb_fixup code to get an idea.

But basically there are "chunks" of 2MB (I think) of contingous memory
that is swizzled in to the memory that starts at io_tlb_start. But
all of that memory SHOULD be under the 4GB limit (set by max_dma_bits).

Sadly in your case one of those "chunks" ends up being past the 4GB
limit - which should never happen. Or if it did happen it would print
out "Failed to get contiguous memory for DMA from.."

But you don't get any of that.

To get a good idea of this, you could do something like this

unsigned long mfn, next_mfn;

mfn= PFN_DOWN(phys_to_machine(XPADDR(pstart)).maddr);

for (i = pstart; i < pend;) {
	next_mfn = PFN_DOWN(phys_to_machine(XPADDR(i)).maddr);
	if (next_mfn == mfn+1) {
		mfn++;
	} else {
		printk(KERN_INFO "MFN 0x%lx->0x%lx\n", mfn, next_mfn);
		mfn = next_mfn;
	}
	i+=PAGE_SIZE;
}

which should print you those "chunks", if my logic here is right.

Can you send me your 'xl info' (or 'xl dmesg'), please?

I tried to reproduce this with a 3.0.4 kernel on a 8GB and I couldn't
reproduce this. Hm, will look in your .config in case there is something
funky there.

We're not getting so far along as to be running xend yet. That normally gets started remotely and without networks it doesn't happen. I can probably do that tomorrow.

You might want to instrument the xen_swiotlb_fixup code to get an idea.

But basically there are "chunks" of 2MB (I think) of contingous memory
that is swizzled in to the memory that starts at io_tlb_start. But
all of that memory SHOULD be under the 4GB limit (set by max_dma_bits).

Sadly in your case one of those "chunks" ends up being past the 4GB
limit - which should never happen. Or if it did happen it would print
out "Failed to get contiguous memory for DMA from.."

But you don't get any of that.


To get a good idea of this, you could do something like this

unsigned long mfn, next_mfn;

mfn= PFN_DOWN(phys_to_machine(XPADDR(pstart)).maddr);

for (i = pstart; i < pend;) {
	next_mfn = PFN_DOWN(phys_to_machine(XPADDR(i)).maddr);
	if (next_mfn == mfn+1) {
		mfn++;
	} else {
		printk(KERN_INFO "MFN 0x%lx->0x%lx\n", mfn, next_mfn);
		mfn = next_mfn;
	}
	i+=PAGE_SIZE;
}

which should print you those "chunks", if my logic here is right.


Can you send me your 'xl info' (or 'xl dmesg'), please?

I tried to reproduce this with a 3.0.4 kernel on a 8GB and I couldn't
reproduce this. Hm, will look in your .config in case there is something
funky there.

The last quoted printout is calculated the same way as the test that fails which leads me to question the computation's validity.

The test that fails is (from drivers/xen/swiotlb-xen.c):
xen_swiotlb_dma_supported(struct device *hwdev, u64 mask)
{
        return xen_virt_to_bus(xen_io_tlb_end - 1) <= mask;
}


"xen_virt_to_bus" in turn:
static dma_addr_t xen_virt_to_bus(void *address)
{
        return xen_phys_to_bus(virt_to_phys(address));
}


Now, "virt_to_phys" (out of arch/x86/include/asm/io.h) is defined as follows but carries a comment bothersome to this usage of it as we're, basically, dealing with a dma "transfer" and calling from a device driver:
/**
 *      virt_to_phys    -       map virtual addresses to physical
 *      @address: address to remap
 *
 *      The returned physical address is the physical (CPU) mapping for
 *      the memory address given. It is only valid to use this function on
 *      addresses directly mapped or allocated via kmalloc.
 *
 *      This function does not give bus mappings for DMA transfers. In
 *      almost all conceivable cases a device driver should not be using
 *      this function
 */ 
static inline phys_addr_t virt_to_phys(volatile void *address)
{
        return __pa(address);
}


Going a couple of steps further, "__pa" is defined (in arch/x86/include/asm/page.h) as:
#define __pa(x)         __phys_addr((unsigned long)(x))


and "__phys_addr" (in arch/x86/mm/physaddr.c) as:
unsigned long __phys_addr(unsigned long x)
{
        if (x >= __START_KERNEL_map) {
                x -= __START_KERNEL_map;
                VIRTUAL_BUG_ON(x >= KERNEL_IMAGE_SIZE);
                x += phys_base;
        } else {
                VIRTUAL_BUG_ON(x < PAGE_OFFSET);
                x -= PAGE_OFFSET;
                VIRTUAL_BUG_ON(!phys_addr_valid(x));
        }
        return x;
}
EXPORT_SYMBOL(__phys_addr);


So, if "virt_to_phys" isn't yielding a valid test of whether addresses will be reachable from a PCI device, what's the correct way to test it and should xen_swiotlb_dma_supported be updated to the correct way (I think so) or a new function be created?

The computation validity seems OK to me (the 'phys' address is, as correctly stated 
in the comments, not suitable for DMA, but it is first translated via 
xen_phys_to_bus, which gives the machine address - and on x86 that is also the bus 
address)

I have a STUPID question, though: why are the start and end addresses of the swiotlb 
memory area not page-aligned???

The io_tlb_end address is one byte PAST the valid area, which is why the 
xen_swiotlb_dma_supported function uses (xen_io_tlb_end-1). However, this will work 
properly only if the value is page-aligned. If it isn't, then decrementing it by one 
will keep the value in the same page (which is one page past the last valid one).

The function that allocates the memory uses alloc_bootmem(), which provides just 
cache-aligned memory (not page-aligned).

If it is OK for the swiotlb area not to be page-aligned, then the 
xen_swiotlb_dma_supported should use (xen_io_tlb_end - (PAGE_SIZE-1))

If the memory should be in fact aligned, then the allocation must be changed to 
alloc_bootmem_pages() (which is the same as alloc_bootmem, but page-aligned).

Yup.

It is actually funny (sad?), b/c I am the committer for the
e79f86b2ef9c0a8c47225217c1018b7d3d90101c which adds something like this:

 alloc_bootmem_pages(PAGE_ALIGN(io_tlb_nslabs * sizeof(int)

in the swiotlb code but I completly missed doing it for the Xen SWIOTLB.

<sigh>

I think this patch:

Yup.

It is actually funny (sad?), b/c I am the committer for the
e79f86b2ef9c0a8c47225217c1018b7d3d90101c which adds something like this:

 alloc_bootmem_pages(PAGE_ALIGN(io_tlb_nslabs * sizeof(int)

in the swiotlb code but I completly missed doing it for the Xen SWIOTLB.

<sigh>

I think this patch:

Subject: [PATCH] xen/swiotlb: Use page alignment for early buffer allocation.

This piggybacks on git commit e79f86b2ef9c0a8c47225217c1018b7d3d90101c
"swiotlb: Use page alignment for early buffer allocation" which:

"We could call free_bootmem_late() if swiotlb is not used, and
it will shrink to page alignment.

So alloc them with page alignment at first, to avoid lose two pages"

Lets make it page aligned.

Sure! But only if 3.0.4 is recent enough. However, that version does not have the code for the "free_bootmem" section of this patch so only the first line was actually tested. (Not that I could test the negative case if the code existed.)

I'll test on a more recent version (your pick) tomorrow, should you prefer.

Just as long as your modified code has this:

  alloc_bootmem_pages(PAGE_ALIGN(bytes));

then that is great!

(The free_bootmem we can ignore for the 3.0.4 kernel).

The modified code has that. It's tested. It works.

At Leonid's suggestion (and provision of a patch) I tried it with page aligned memory and it works. Is this "the" real solution or just a change that happens to make things work for the case I have?  The patch I used is:

--- a/drivers/xen/swiotlb-xen.c

        if (!xen_io_tlb_start)
                panic("Cannot allocate SWIOTLB buffer");

The test that was failing now passes: finding the "bus" address of 7f3ffff to be within a 32-bit mask and the last few MFN entries are:

The computation validity seems OK to me (the 'phys' address is, as correctly stated 
in the comments, not suitable for DMA, but it is first translated via 
xen_phys_to_bus, which gives the machine address - and on x86 that is also the bus 
address)

I have a STUPID question, though: why are the start and end addresses of the swiotlb 
memory area not page-aligned???

The io_tlb_end address is one byte PAST the valid area, which is why the 
xen_swiotlb_dma_supported function uses (xen_io_tlb_end-1). However, this will work 
properly only if the value is page-aligned. If it isn't, then decrementing it by one 
will keep the value in the same page (which is one page past the last valid one).

The function that allocates the memory uses alloc_bootmem(), which provides just 
cache-aligned memory (not page-aligned).

If it is OK for the swiotlb area not to be page-aligned, then the 
xen_swiotlb_dma_supported should use (xen_io_tlb_end - (PAGE_SIZE-1))

If the memory should be in fact aligned, then the allocation must be changed to 
alloc_bootmem_pages() (which is the same as alloc_bootmem, but page-aligned).

Neal, I would also strongly recommend you try v3.0.6 - as there are a
couple of important fixes in it:

310fef9 xen/e820: if there is no dom0_mem=, don't tweak extra_pages.
0208b80 xen: use maximum reservation to limit amount of usable RAM
d63c8a0 mm: sync vmalloc address space page tables in alloc_vm_area()
0b129e1 xen/smp: Warn user why they keel over - nosmp or noapic and what
to use instead.
1f51b5d xen: x86_32: do not enable iterrupts when returning from
exception in interrupt context

Especially the dom0_mem - which I think you are using but the values are not
