Subject: [PATCH] brcmfmac: Add DMI nvram filename quirk for ACEPC T8 and T11
|
||
|
|
mini PCs
|
||
|
|
|
||
|
|
The ACEPC T8 and T11 mini PCs contain quite generic names in the sys_vendor
|
||
|
|
and product_name DMI strings, without this patch brcmfmac will try to load:
|
||
|
|
"brcmfmac43455-sdio.Default string-Default string.txt" as nvram file which
|
||
|
|
is way too generic.
|
||
|
|
|
||
|
|
The DMI strings on which we are matching are somewhat generic too, but
|
||
|
|
"To be filled by O.E.M." is less common then "Default string" and the
|
||
|
|
system-sku and bios-version strings are pretty unique. Beside the DMI
|
||
|
|
strings we also check the wifi-module chip-id and revision. I'm confident
|
||
|
|
that the combination of all this is unique.
|
||
|
|
|
||
|
|
Both the T8 and T11 use the same wifi-module, this commit adds DMI
|
||
|
|
quirks for both mini PCs pointing to brcmfmac43455-sdio.acepc-t8.txt .
