The patches were generated from the RPi repo with the following command: git format-patch v6.6.34..rpi-6.1.y Some patches needed rebasing and, as usual, the applied and reverted, wireless drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 1089/1135] DTS: bcm2712: set nonzero QoS values for PCIE1
|
|
|
|
If PCIE1 is left with the default (zero) AXI QoS values, endpoints can
|
|
receive extremely poor service for non-posted transactions e.g. reads.
|
|
Such transactions can take milliseconds to complete on a contended
|
|
system.
|
|
|
|
Bump priorities for every TC above the non-realtime greedy peripherals
|
|
in BCM2712, to allow reasonable service without competing against hard
|
|
realtime peripherals.
