wifi: iwlwifi: pcie: fix byte count table for some devices

2025-10-02T11:48:39+00:00

commit a38108a23ab558b834d71d542d32c05ab0fb64d4 upstream.

In my previous fix for this condition, I erroneously listed 9000
instead of 7000 family, when 7000/8000 were already using iwlmvm.
Thus the condition ended up wrong, causing the issue I had fixed
for older devices to suddenly appear on 7000/8000 family devices.
Correct the condition accordingly.

wifi: iwlwifi: fix byte count table for old devices

2025-10-02T11:48:39+00:00

commit 586e3cb33ba6890054b95aa0ade0a165890efabd upstream.

For devices handled by iwldvm, bc_table_dword was never set, but I missed
that during the removal thereof. Change the logic to not treat the byte
count table as dwords for devices older than 9000 series to fix that.

wifi: iwlwifi: fix 130/1030 configs

2025-09-19T14:37:31+00:00

commit 2682e7a317504a9d81cbb397249d4299e84dfadd upstream.

The 130/1030 devices are really derivatives of 6030,
with some small differences not pertaining to the MAC,
so they must use the 6030 MAC config.

wifi: iwlwifi: cfg: add back more lost PCI IDs

[ Upstream commit 019f71a6760a6f89d388c3cd45622d1aae7d3641 ]

Add back a few more PCI IDs to the config match table that
evidently I lost during the cleanups.

wifi: iwlwifi: cfg: restore some 1000 series configs

[ Upstream commit 22e6bdb129ec64e640f5cccef9686f7c1a7d559b ]

In the fixed commit, I inadvertently removed two configurations
while combining the 0x0083/0x0084 device IDs. Replace the fixed
matches for the BG versions by a masked match and add the BGN
version back with a similar masked match.

[ Upstream commit 224476613c8499f00ce4de975dd65749c5ca498c ]

We want to see bits being set in the scratch register upon resume, but
if all the bits are set, it means that we were kicked out of the PCI bus
and that clearly doesn't mean we can assume the firmware is still alive
after the suspend / resume cycle.
