Subject: [PATCH] wifi: ath11k: use unique QRTR instance ID
|
|
|
|
Currently, trying to use AHB + PCI/MHI cards or multiple PCI/MHI cards
|
|
will cause a clash in the QRTR instance node ID and prevent the driver
|
|
from talking via QMI to the card and thus initializing it with:
|
|
[ 9.836329] ath11k c000000.wifi: host capability request failed: 1 90
|
|
[ 9.842047] ath11k c000000.wifi: failed to send qmi host cap: -22
|
|
|
|
So, in order to allow for this combination of cards, especially AHB + PCI
|
|
cards like IPQ8074 + QCN9074 (Used by me and tested on) set the desired
|
|
QRTR instance ID offset by calculating a unique one based on PCI domain
|
|
and bus ID-s and writing it to bits 7-0 of BHI_ERRDBG2 MHI register by
|
|
using the SBL state callback that is added as part of the series.
|
|
We also have to make sure that new QRTR offset is added on top of the
|
|
default QRTR instance ID-s that are currently used in the driver.
|
|
|
|
This finally allows using AHB + PCI or multiple PCI cards on the same
|
|
system.
|
|
|
|
Since this is not supported on QCA6390 and like, its limited to QCN9074
|
|
which is known to support changing QRTR instance ID.
