[PATCH net-next 0/6] net: ipa: start using transaction IDs

[Alex Elder]

A previous group of patches added ID fields to track the state of
transactions:
  https://lore.kernel.org/netdev/20220831224017.377745-1-elder@linaro.org

This series starts using those IDs instead of the lists used
previously.  Most of this series involves reworking the function
that determines which transaction is the "last", which determines
when a channel has been quiesed.  The last patch is mainly used to
prove that the new index method of tracking transaction state is
equivalent to the previous use of lists.

[PATCH net-next 1/6] net: ipa: rework last transaction determination

[Alex Elder]

When quiescing a channel, we find the "last" transaction, which is
the latest one to have been allocated.  (New transaction allocation
will have been prevented by the time this is called.)

Currently we do this by looking for the first non-empty transaction
list in each state, then return the last entry from that last.
Instead, determine the last entry in each list (if any) and return
that entry if found.

Temporarily (locally) introduce list_last_entry_or_null() as a
helper for this, mirroring list_first_entry_or_null().  This macro
definition will be removed by an upcoming patch.

Remove the temporary warnings added by the previous commit.

[PATCH net-next 2/6] net: ipa: use IDs for last allocated transaction

[Alex Elder]

Use the allocated and free transaction IDs to determine whether the
"last" transaction used for quiescing a channel is in allocated
state.  The last allocated transaction that has not been committed
(if any) immediately precedes the first free transaction in the
transaction array.

[PATCH net-next 3/6] net: ipa: use IDs exclusively for last transaction

[Alex Elder]

Always use transaction IDs when finding the "last" transaction to
await when quiescing a channel.  This basically extends what was
done in the previous patch to all other transaction state IDs.

As a result we are no longer updating any transaction lists inside
gsi_channel_trans_last(), so there's no need to take the spinlock.

[PATCH net-next 4/6] net: ipa: simplify gsi_channel_trans_last()

[Alex Elder]

Using a little logic we can simplify gsi_channel_trans_last().

The first condition in that function looks like this:
    if (trans_info->allocated_id != trans_info->free_id)
And if that's false, we proceed to the next one:
    if (trans_info->committed_id != trans_info->allocated_id)

Failure of the first test implies:
    trans_info->allocated_id == trans_info->free_id
And therefore, the second one can be rewritten this way:
    if (trans_info->committed_id != trans_info->free_id)

Substituting free_id for allocated_id and committed_id can also be
done in the code blocks executed when these conditions yield true.
The net result is that all three blocks for TX endpoints can be
consolidated into just one.

The two blocks of code at the end of that function (used for both TX
and RX channels) can be similarly consolidated into a single block.

[PATCH net-next 6/6] net: ipa: verify a few more IDs

[Alex Elder]

The completed transaction list is used in gsi_channel_trans_complete()
to return the next transaction in completed state.

Add some temporary checks to verify the transaction indicated by the
completed ID matches the one first in this list.

Similarly, we use the pending and completed transaction lists when
cancelling pending transactions in gsi_channel_trans_cancel_pending().

Add temporary checks there to verify the transactions indicated by
IDs match those tracked by these lists.
