From: Luca Coelho <[email protected]>
Hi,
Here's the fifth set of patches intended for v5.12. It's the usual
development, new features, cleanups and bugfixes.
The changes are:
* Add some device IDs that got lost in a rebase;
* A bunch of fixes in the PPAG code;
* Some other small fixes, clean-ups and improvements.
As usual, I'm pushing this to a pending branch, for kbuild bot, and
will send a pull-request later.
Please review.
Cheers,
Luca.

From: Luca Coelho <[email protected]>
We were erroneously adding 3 extra values to the table size
calculation, when we should actually add only a 2 (one for the domain
type and one for the enabled/disabled flag). Fix this for both
revisions we support.

Some change conflicts apparently cause a confusion between a local
variable being used to send the PPAG command and the introduction of a
union for this command. Most parts of the local command were never
copied from the stored data, so the FW was getting garbage in the
tables instead of getting valid values.
Fix this by completely removing the local and using only the union
that we have stored in fwrt.

The only thing we do touching the device in hard interrupt context
is, at most, writing an interrupt ACK register, which isn't racing
in with anything protected by the reg_lock.
Thus, avoid disabling interrupts here for potentially long periods
of time, particularly long periods have been observed with dumping
of firmware memory (leading to lockup warnings on some devices.)

Remember that those pointers have been freed by setting them
to NULL. Otherwise, we'd keep rxq pointing to random memory
which would prevent us from trying to re-allocate the Rx
resources if we call rx_alloc again.
Also, propagate the allocation failure to the caller of
iwl_pcie_nic_init so that we won't go further in the
start flow.

From: Luca Coelho <[email protected]>
When reading the PPAG table from ACPI, we should store everything in
our fwrt structure, so it can be accessed later. But we had a local
ppag_table variable in the function and were erroneously storing the
enabled/disabled flag in it instead of storing it in the fwrt. Fix
this by removing the local variable and storing everything directly in
fwrt.

From: Luca Coelho <[email protected]>
The value we receive from ACPI is a long long unsigned integer but the
values should be treated as signed char. When comparing the received
value with ACPI_PPAG_MIN_LB/HB, we were doing an unsigned comparison,
so the negative value would actually be treated as a very high number.
To solve this issue, assign the value to our table of s8's before
making the comparison, so the value is already converted when we do
so.

From: Luca Coelho <[email protected]>
The call to iwl_sar_geo_init() was moved to the end of the
iwl_mvm_sar_geo_init() function, after the table revision is assigned
to the FW command. But the revision is only known after
iwl_sar_geo_init() is called, so we were always assigning zero to it.
Fix that by moving the assignment code after the iwl_sar_geo_init()
function is called.
