This revision is to address two problems found by Horst H. von Brand while
testing the v2 patches in Fedora:
https://bugzilla.redhat.com/show_bug.cgi?id=637647
On his machine, we don't use _CRS by default, and the BIOS left some bridge
windows disabled.
Problem 1: When we assigned space for the windows, we started at the top
and allocated [mem 0xffffffffffe00000-0xffffffffffffffff], which is
obviously useless because the CPU doesn't support physical addresses that
large.
Problem 2: Subsequent allocations failed because I made an error in
find_resource(). We look for available space from [child->end + 1 to
root->end], and if the last child ends exactly at 0xffffffffffffffff, we
wrap around and start from zero.
I made the top-down allocation conditional: an arch can select it at
boot-time, and there's a kernel command line option to change it for
debugging.
When we move PCI devices, we currently allocate space bottom-up, i.e., we look
at PCI bus resources in the order we found them, we look at gaps between child
resources bottom-up, and we align the new space at the bottom of an available
region.
On x86, we move PCI devices more than we used to because we now pay attention
to the PCI host bridge windows from ACPI. For example, when we find a device
that's outside all the known host bridge windows, we try to move it into a
window, and we look for space starting at the bottom.
Windows does similar device moves, but it looks for space top-down rather than
bottom-up. Since most machines are better-tested with Windows than Linux, this
difference means that Linux is more likely to trip over BIOS bugs in the PCI
host bridge window descriptions than Windows is.
We've had several reports of Dell machines where the BIOS leaves the AHCI
controller outside the host bridge windows (BIOS bug #1), *and* the lowest
host bridge window includes an area that doesn't actually reach PCI (BIOS
bug #2). The result is that Windows (which moves AHCI to the top of a window)
works fine, while Linux (which moves AHCI to the bottom, buggy, area) doesn't
work.
These patches change Linux to allocate space more like Windows does:
1) The x86 pcibios_align_resource() will choose space from the
end of an available area, not the beginning.
2) In the generic allocate_resource() path, we'll look for space
between existing children from the top, not from the bottom.
3) When pci_bus_alloc_resource() looks for available space, it
will start from the highest window, not the first one we found.
This series fixes a 2.6.34 regression that prevents many Dell Precision
workstations from booting:
https://bugzilla.kernel.org/show_bug.cgi?id=16228
Changes from v3 to v4:
- Use round_down() rather than adding ALIGN_DOWN().
- Replace ARCH_HAS_TOP_DOWN_ALLOC #define with a boot-time architecture
choice and add a "resource_alloc_from_bottom" command line option to
revert to the old behavior (NOTE: this only affects allocate_resource(),
not pcibios_align_resource() or pci_bus_alloc_resource()).
- Fixed find_resource_from_top() again; it still didn't handle a child
that ended at the parent's end correctly.
Changes from v2 to v3:
- Updated iomem_resource.end to reflect the end of usable physical address
space. Otherwise, we might allocate right up to 0xffffffff_ffffffff,
which isn't usable.
- Make allocate_resource() change conditional on ARCH_HAS_TOP_DOWN_ALLOC.
Without arch-specific changes like the above, it's too dangerous to
make this change for everybody at once.
- Fix 64-bit wraparound in find_resource(). If the last child happened
to end at ~0, we computed the highest available space as [child->end + 1,
root->end], which makes us think the available space started at 0,
which makes us return space that may already be allocated.
Changes from v1 to v2:
- Moved check for allocating before the available area from
pcibios_align_resource() to find_resource(). Better to do it
after the alignment callback is done, and make it generic.
- Fixed pcibios_align_resource() alignment. If we start from the
end of the available area, we must align *downward*, not upward.
- Fixed pcibios_align_resource() ISA alias avoidance. Again, since
the starting point is the end of the area, we must align downward
when we avoid aliased areas.

The alignment callback returns a proposed location, which may have been
adjusted to avoid ISA aliases or for other architecture-specific reasons.
We already had a check ("tmp.start < tmp.end") to make sure the callback
doesn't return a location above the available area.
This patch adds a check to make sure the callback doesn't return something
*below* the available area, as may happen if the callback tries to allocate
top-down.

Allocate space from the top of a region first, then work downward,
if an architecture desires this.
When we allocate space from a resource, we look for gaps between children
of the resource. Previously, we always looked at gaps from the bottom up.
For example, given this:
[mem 0xbff00000-0xf7ffffff] PCI Bus 0000:00
[mem 0xbff00000-0xbfffffff] gap -- available
[mem 0xc0000000-0xdfffffff] PCI Bus 0000:02
[mem 0xe0000000-0xf7ffffff] gap -- available
we attempted to allocate from the [mem 0xbff00000-0xbfffffff] gap first,
then the [mem 0xe0000000-0xf7ffffff] gap.
With this patch an architecture can choose to allocate from the top gap
[mem 0xe0000000-0xf7ffffff] first.
We can't do this across the board because iomem_resource.end is initialized
to 0xffffffff_ffffffff on 64-bit architectures, and most machines can't
address the entire 64-bit physical address space. Therefore, we only
allocate top-down if the arch requests it by clearing
"resource_alloc_from_bottom".

Allocate space from the highest-address PCI bus resource first, then work
downward.
Previously, we looked for space in PCI host bridge windows in the order
we discovered the windows. For example, given the following windows
(discovered via an ACPI _CRS method):
pci_root PNP0A03:00: host bridge window [mem 0x000a0000-0x000bffff]
pci_root PNP0A03:00: host bridge window [mem 0x000c0000-0x000effff]
pci_root PNP0A03:00: host bridge window [mem 0x000f0000-0x000fffff]
pci_root PNP0A03:00: host bridge window [mem 0xbff00000-0xf7ffffff]
pci_root PNP0A03:00: host bridge window [mem 0xff980000-0xff980fff]
pci_root PNP0A03:00: host bridge window [mem 0xff97c000-0xff97ffff]
pci_root PNP0A03:00: host bridge window [mem 0xfed20000-0xfed9ffff]
we attempted to allocate from [mem 0x000a0000-0x000bffff] first, then
[mem 0x000c0000-0x000effff], and so on.
With this patch, we allocate from [mem 0xff980000-0xff980fff] first, then
[mem 0xff97c000-0xff97ffff], [mem 0xfed20000-0xfed9ffff], etc.
Allocating top-down follows Windows practice, so we're less likely to
trip over BIOS defects in the _CRS description.
On the machine above (a Dell T3500), the [mem 0xbff00000-0xbfffffff] region
doesn't actually work and is likely a BIOS defect. The symptom is that we
move the AHCI controller to 0xbff00000, which leads to "Boot has failed,
sleeping forever," a BUG in ahci_stop_engine(), or some other boot failure.

Allocate from the end of a region, not the beginning.
For example, if we need to allocate 0x800 bytes for a device on bus
0000:00 given these resources:
[mem 0xbff00000-0xdfffffff] PCI Bus 0000:00
[mem 0xc0000000-0xdfffffff] PCI Bus 0000:02
the available space at [mem 0xbff00000-0xbfffffff] is passed to the
alignment callback (pcibios_align_resource()). Prior to this patch, we
would put the new 0x800 byte resource at the beginning of that available
space, i.e., at [mem 0xbff00000-0xbff007ff].
With this patch, we put it at the end, at [mem 0xbffff800-0xbfffffff].

The iomem_resource map reflects the available physical address space.
We statically initialize the end to -1, i.e., 0xffffffff_ffffffff, but
of course we can only use as much as the CPU can address.
This patch updates the end based on the CPU capabilities, so we don't
mistakenly allocate space that isn't usable, as we're likely to do when
allocating from the top-down.

Request that allocate_resource() use available space from high addresses
first, rather than the default of using low addresses first.
The most common place this makes a difference is when we move or assign
new PCI device resources. Low addresses are generally scarce, so it's
better to use high addresses when possible. This follows Windows practice
for PCI allocation.

PNPACPI: cope with invalid device IDs
If primary ID (HID) is invalid try locating first valid ID on compatible
ID list before giving up.
This helps, for example, to recognize i8042 AUX port on Sony Vaio VPCZ1
which uses SNYSYN0003 as HID. Without the patch users are forced to
boot with i8042.nopnp to make use of their touchpads.
