To: u-boot
At present each device has two sequence numbers, with 'req_seq' being
set up at bind time and 'seq' at probe time. The idea is that devices
can 'request' a sequence number and then the conflicts are resolved when
the device is probed.
This makes things complicated in a few cases, since we don't really know
(at bind time) what the sequence number will end up being. We want to
honour the bind-time requests if at all possible, but in fact the only
source of these at present is the devicetree aliases.
Apart from the obvious need for sequence numbers to supports U-Boot's
numbering on devices on the command line, the current scheme was
designed to:
- avoid calculating the sequence number until it is needed, to save
execution time
- allow multiple devices to obtain a particular sequence number as they
are probed and removed
- retain a record of the 'requested' sequence number even if it turns out
that a device could not get it (to allow debugging and retrying)
After some years using the current scheme it seems on balance that these
goals don't have as much merit as first thought. The first point would
be persuasive except that we end up reading the devicetree aliases at
bind-time anyway. So the work of resolving the sequence numbers during
probing is not that great. The second point hasn't really been an issue,
as there is typically no contention for sequence numbers (boards tend to
allocate them statically in the devicetree). Re the third point, we can
often figure out what was requested by looking at aliases, and in the
cases where we can't, it doesn't seem to matter much.
Since we have the devicetree available at bind time, we may as well just
use it, in the hope that the required processing will turn out to be
useful later (i.e. the device actually gets used). In addition, it is
simpler to use a single sequence number, since it avoids confusion and
some extra code.
This series moves U-Boot to use a single, bind-time sequence number. All
uclasses assign sequence numbers to their devices, so that as soon as a
device is bound, it has a sequence number. If the uclass flag
DM_UC_FLAG_SEQ_ALIAS is enabled (as well as the CONFIG option), a
devicetree alias provides the number. Otherwise, the next available number
(after the last alias and avoiding existing devices) is used.
Apart from the simplicity gains, overall these changes seem to reduce the
number of tweaks and workarounds needed to get the desired behaviour.
However there will certainly be some problems created, so board
maintainers should test this out.
This series is available at u-boot-dm/seq-working
Changes in v2:
- Give all devices a sequence number
- Drop uclass_alloc_all_seqs() and GD_FLG_DM_NO_SEQ flag
- Drop the GD_FLG_DM_NO_SEQ flag
- Use the sequence number directly instead of max bus
- Adjust the tests to handle the new allocation scheme
- Drop the networking changes which are no-longer needed
- Update for new logic
- Adjust commit message
- Drop pointless check for max == -1
- Adjust the tests to handle the new allocation scheme
- Simplify the logic so auto_seq is positive
- Update the docs to indicate all devices get a sequence number
- Update the docs to explain how aliases reserve sequence numbers
- Drop commit changing efi_uc_destroy()

The linker script uses alphabetic sorting to group the different linker
lists together. Each group has its own struct and potentially its own
alignment. But when the linker packs the structs together it cannot ensure
that a linker list starts on the expected alignment boundary.
For example, if the first list has a struct size of 8 and we place 3 of
them in the image, that means that the next struct will start at offset
0x18 from the start of the linker_list section. If the next struct has
a size of 16 then it will start at an 8-byte aligned offset, but not a
16-byte aligned offset.
With sandbox on x86_64, a reference to a linker list item using
ll_entry_get() can force alignment of that particular linker_list item,
if it is in the same file as the linker_list item is declared.
Consider this example, where struct driver is 0x80 bytes:
ll_entry_declare(struct driver, fred, driver)
...
void *p = ll_entry_get(struct driver, fred, driver)
If these two lines of code are in the same file, then the entry is forced
to be aligned at the 'struct driver' alignment, which is 16 bytes. If the
second line of code is in a different file, then no action is taken, since
the compiler cannot update the alignment of the linker_list item.
In the first case, an 8-byte 'fill' region is added:
.u_boot_list_2_driver_2_testbus_drv
0x0000000000270018 0x80 test/built-in.o
0x0000000000270018 _u_boot_list_2_driver_2_testbus_drv
.u_boot_list_2_driver_2_testfdt1_drv
0x0000000000270098 0x80 test/built-in.o
0x0000000000270098 _u_boot_list_2_driver_2_testfdt1_drv
*fill* 0x0000000000270118 0x8
.u_boot_list_2_driver_2_testfdt_drv
0x0000000000270120 0x80 test/built-in.o
0x0000000000270120 _u_boot_list_2_driver_2_testfdt_drv
.u_boot_list_2_driver_2_testprobe_drv
0x00000000002701a0 0x80 test/built-in.o
0x00000000002701a0 _u_boot_list_2_driver_2_testprobe_drv
With this, the linker_list no-longer works since items after testfdt1_drv
are not at the expected address.
Ideally we would have a way to tell gcc not to align structs in this way.
It is not clear how we could do this, and in any case it would require us
to adjust every struct used by the linker_list feature.
One possible fix is to force each separate linker_list to start on the
largest possible boundary that can be required by the compiler. However
that does not seem to work on x86_64, which uses 16-byte alignment in this
case but needs 32-byte alignment.
So add a Kconfig option to handle this. Set the default value to 4 so
as to avoid changing platforms that don't need it.
Update the ll_entry_start() accordingly.

At present various drivers etc. access the device's 'seq' member directly.
This makes it harder to change the meaning of that member. Change access
to go through a function instead.
The drivers/i2c/lpc32xx_i2c.c file is left unchanged for now.

At present this is passed a uclass ID and it has to do a lookup. The
callers all have the uclass pointer, except for the I2C uclass where the
code will soon be deleted.
Update the argument to a uclass * instead of an ID since it is more
efficient.

At present each device has two sequence numbers, with 'req_seq' being
set up at bind time and 'seq' at probe time. The idea is that devices
can 'request' a sequence number and then the conflicts are resolved when
the device is probed.
This makes things complicated in a few cases, since we don't really know
what the sequence number will end up being. We want to honour the
bind-time requests if at all possible, but in fact the only source of
these at present is the devicetree aliases. Since we have the devicetree
available at bind time, we may as well just use it, in the hope that the
required processing will turn out to be useful later (i.e. the device
actually gets used).
Add a new 'sqq' member, the bind-time sequence number. It operates in
parallel to the old values for now. All devices get a valid sqq value,
i.e. it is never -1.
Drop an #ifdef while we are here.

Several Octeon drivers operate by setting the sequence number of their
device. This should not be needed with the new sequence number setup. Also
it is not permitted. Drop it.

Use the new sequence number in all cases. Drop the logic to check for a
valid number in designware_i2c, since it will always be valid.

Checking for seq == -1 is effectively checking that the device is
activated. The new sequence numbers are never -1 for a bound device, so
update the check.
Also drop the note about valid sequence numbers so it is accurate with the
new approach.

Now that we know the sequence number at bind time, there is no need for
special-case code in dm_pci_hose_probe_bus().
Note: the PCI_CAP_ID_EA code may need a look, but there are no test
failures so I have left it as is.

the sequence number should be 0 anyway, and assigning to the sequence

not needed. Also, we should use dev_seq() instead of req_seq. Update the
whole file accordingly.
Also fix up APL cpu while we are here.

There is no-longer any need to check if sequence numbers are valid, since
this is ensured by driver model. Drop the unwanted logic.

This function current deals with req_seq which is deprecated. Update it to
use the new sequence numbers, putting them above existing aliases. Rename
the function to make this clear.

Now that migration to the new sequence numbers is complete, drop the old
fields. Add a test that covers the new behaviour.
Also drop the check for OF_PRIOR_STAGE since we always assign sequence
numbers now.

Changes in v2:
- Update the docs to indicate all devices get a sequence number
- Update the docs to explain how aliases reserve sequence numbers
- Drop commit changing efi_uc_destroy()

Thanks for trying this out.
I suppose you have a different problem from what I found in v1. Can
you please send the output of these things before and after the
change?
dm tree
dm uc
pci
pci 1
(e.g. for other buses)
pci 0 long
Which board is it? I suppose there is a chance I have one.
Thanks,
Simon

Thanks for the info. I was worried that the renumbering might cause
problems but saw no issues on my x86 board.
If you look at the sequence numbers for PCI they have changed. They
also correspond to the bus numbers, and PCI uses the sub bus number to
route access to sub bus, so I suspect one of your buses is not getting
traffic.
At present the only fix is to add all buses into the DT. I'll take a
look and see what else I can do.
Regards,
Simon

I've pushed an experimental tree to u-boot-dm/seq3-working
Are you able to take a look and send the same output as last time? I
am trying to change how PCI allocation happens, so that it follows the
PCI rules. Hopefully the change makes sense to you but I would
appreciate any insights you may have.

Simon

While it seems to work better now; this looks strange

Sorry I haven't found time to look into this, yet.

From what I can tell, ls_pcie_probe() is being called twice for each PCIe bus.
This can normally only happen if, when probing a device, the uclass
/child pre/post--probe itself probes the same device.
But I'm not sure what has changed about the PCI init sequence to cause this.
