request_free_mem_region() is used to find an empty range of physical
addresses for hotplugging ZONE_DEVICE memory. It does this by iterating
over the range of possible addresses using region_intersects() to see if
the range is free.

region_intersects() obtains a read lock before walking the resource tree
to protect against concurrent changes. However it drops the lock prior
to returning. This means by the time request_mem_region() is called in
request_free_mem_region() another thread may have already reserved the
requested region resulting in unexpected failures and a message in the
kernel log from hitting this condition:

        /*
         * mm/hmm.c reserves physical addresses which then
         * become unavailable to other users.  Conflicts are
         * not expected.  Warn to aid debugging if encountered.
         */
        if (conflict->desc == IORES_DESC_DEVICE_PRIVATE_MEMORY) {
                pr_warn("Unaddressable device %s %pR conflicts with %pR",
                        conflict->name, conflict, res);

To fix this create versions of region_intersects() and
request_mem_region() that allow the caller to take the appropriate lock
such that it may be held over the required calls.

Instead of creating another version of devm_request_mem_region() that
doesn't take the lock open-code it to allow the caller to pre-allocate
the required memory prior to taking the lock.

is_type is a bad name, are we saying "is" as in boolean question?
Or is it short for something like intersection_type? I know you've
just moved the code over :)

This part of the diff looks confusing, do we have a waitqueue and we call
schedule() within a function called with the lock held?

Should the function be called __request_region_locked?

Just a high-level question: how does this iteract with memory 
hot(un)plug? IOW, how defines and manages the "range of possible 
addresses" ?

I am confused. Why can't we return an error to the caller and let the 
caller continue searching? This feels much simpler than what you propose 
here. What am I missing?

Both the driver and the maximum physical address bits available define the 
range of possible addresses for device private memory. From 
__request_free_mem_region():

end = min_t(unsigned long, base->end, (1UL << MAX_PHYSMEM_BITS) - 1);
addr = end - size + 1UL;

There is no lower address range bound here so it is effectively zero. The code 
will try to allocate the highest possible physical address first and continue 
searching down for a free block. Does that answer your question?

The search occurs as part of the allocation. To allocate memory free space 
needs to be located and allocated as a single operation. However in this case 
the lock is dropped between locating a free region and allocating it resulting 
in an extra debug check firing and subsequent failure.

I did originally consider just allowing the caller to retry, but in the end it 
didn't seem any simpler. Callers would have to differentiate between transient 
and permanent failures and figure out how often to retry and no doubt each 
caller would do this differently. There is also the issue of starvation if one 
thread constantly looses the race to allocate after the search. Overall it 
seems simpler to me to just have a call that allocates a region (or fails due 
to lack of free space).

I also don't think what I am proposing is particularly complex. I agree the 
diff makes it look complex, but at a high level all I'm doing is moving the 
locking to outer function calls. It ends up looking more complex because there 
are some memory allocations which need reordering, but I don't think if things 
were originally written this way it would be considered complex.

Yeah, I'm not a fan of that name either but I was just moving code over and 
couldn't come up with anything better :)

It is a boolean question though - it is checking to see if resource *p is the 
same type (flags+desc) of region as what is being checked for intersection.

Good point. schedule() does get called but the lock is dropped first:

		if (conflict->flags & flags & IORESOURCE_MUXED) {
			add_wait_queue(&muxed_resource_wait, &wait);
			write_unlock(&resource_lock);
			set_current_state(TASK_UNINTERRUPTIBLE);
			schedule();
			remove_wait_queue(&muxed_resource_wait, &wait);
			write_lock(&resource_lock);
			continue;
		}

This isn't an issue though as it's only used for request_muxed_region() which 
isn't used for the ZONE_DEVICE allocation and by design doesn't search for 
free space. Ie. IORESOURCE_MUXED will never be set for 
request_free_mem_region().

This is the name of original function, so this is just maintaining the 
original behaviour by taking the lock and calling the inner function 
(request_region_locked) rather than having it coded directly there.

__request_region() is rarely called directly and is mostly called via macros:

include/linux/ioport.h:#define request_region(start,n,name)             
__request_region(&ioport_resource, (start), (n), (name), 0)
include/linux/ioport.h:#define request_muxed_region(start,n,name)       
__request_region(&ioport_resource, (start), (n), (name), IORESOURCE_MUXED)
include/linux/ioport.h:#define __request_mem_region(start,n,name, excl) 
__request_region(&iomem_resource, (start), (n), (name), excl)
include/linux/ioport.h:#define request_mem_region(start,n,name) 
__request_region(&iomem_resource, (start), (n), (name), 0)

Makes sense, I guess this takes away from the caller having to call
the API again in the case of a conflict (a caller might never succeed
deterministically in the worst case)?

Not sure why I didn't hit this in testing but the problem is obvious: I missed 
that revoke_iomem() calls devmem_is_allowed() which on x86 calls 
region_intersects(). I guess I must have forgotten to do a boot test with 
CONFIG_IO_STRICT_DEVMEM. Will put a fix together.

Right, you would want to return -EBUSY, -ENOMEM,... from 
__request_region() - which somehow seems like the right thing to do 
considering that we can have both types of errors already.

Fair enough, but I doubt the starvation is a real issue ...

Well, it adds another 42 LOC to kernel/resource.c for a rather special 
case that just needs a better return value from __request_region() to 
make a decision.

Oh, sorry, the fist time I had a look I got it wrong - I thought (1UL << 
MAX_PHYSMEM_BITS) would be the lower address limit. That looks indeed 
problematic to me.

You might end up reserving an iomem region that could be used e.g., by 
memory hotplug code later. If someone plugs a DIMM or adds memory via 
different approaches (virtio-mem), memory hotplug (via add_memory()) 
would fail.

You never should be touching physical memory area reserved for memory 
hotplug, i.e., via SRAT.

What is the expectation here?

Most drivers call request_free_mem_region() with iomem_resource as the base. 
So zone device private pages currently tend to get allocated from the top of 
that.

By definition ZONE_DEVICE private pages are unaddressable from the CPU. So in 
terms of expectation I think all that is really required for ZONE_DEVICE 
private pages (at least for Nouveau) is a valid range of physical addresses 
that allow page_to_pfn() and pfn_to_page() to work correctly. To make this 
work drivers add the pages via memremap_pages() -> pagemap_range() -> 
add_pages().

Okay, but you could still "steal" iomem space that does not belong to 
you, and the firmware will be unaware of that (e.g., it might hotplug a 
DIMM in these spots). This is really nasty (although I guess as you 
allocate top down, it will happen rarely).

So you'd actually want some region above the hotpluggable/addressable 
range -- e.g., above MAX_PHYSMEM_BITS.

The maximum number of sections we can have is define by

#define SECTIONS_SHIFT (MAX_PHYSMEM_BITS - SECTION_SIZE_BITS)

You'd e.g., want an extra space like (to be improved)

#define DEVMEM_BITS	1
#define SECTIONS_SHIFT (MAX_PHYSMEM_BITS + DEVMEM_BITS - SECTION_SIZE_BITS)

And do the search only within that range.

Hi Alistair,

Thanks for your patch. But there is a deadlock that should be fixed.
Please see the following scenario.

__request_region
    write_lock(&resource_lock)
        request_region_locked
            revoke_iomem
                devmem_is_allowed (arch/x86/mm/init.c)
                    region_intersects
                        read_lock(&resource_lock)   // deadlock

Thanks for the report and apologies for the breakage. The kernel test robot 
caught it pretty quickly - see https://lore.kernel.org/linux-mm/
20210330003842.18948-1-apopple@nvidia.com/ for an updated version that fixes 
this.
