In the downstream kernel, ACV enable_mask has not been mentioned explicitly, rather being handled by a sneaky if-condition [1], [2]. Add it to all RPMh platforms to actually enable that BCM.

2023-10-09interconnect: qcom: qcm2290: Update EBI channel configurationKonrad Dybcio1-1/+2
QCM2290 can support two memory configurations: single-channel, 32-bit wide LPDDR3 @ up to 933MHz (bus clock) or dual-channel, 16-bit wide LPDDR4X @ up to 1804 MHz. The interconnect driver in its current form seems to gravitate towards the first one, however there are no LPDDR3- equipped boards upstream and we still don't have a great way to discern the DDR generations on the kernel side. To make DDR scaling possible on the only currently-supported 2290 board, stick with the LPDDR4X config by default. The side effect on any potential LPDDR3 board would be that the requested bus clock rate is too high (but still capped to the firmware-configured FMAX).

2023-10-09interconnect: qcom: icc-rpm: Let nodes drive their own bus clockKonrad Dybcio2-0/+31
If this hardware couldn't get messier, some nodes are supposed to drive their own bus clock.. Presumably to connect to some intermediate interface between the node itself and the bus it's (supposed to be) connected to. Expand the node struct with the necessary data and hook up the allocations & calculations. Note that the node-specific AB/IB coefficients contribute (by design) to both the node-level and the bus-level aggregation.

2023-10-09interconnect: qcom: icc-rpm: Add AB/IB calculations coefficientsKonrad Dybcio2-3/+21
Presumably due to the hardware being so complex, some nodes (or busses) have different (usually higher) requirements for bandwidth than what the usual calculations would suggest. Looking at the available downstream files, it seems like AB values are adjusted per-bus and IB values are adjusted per-node. With that in mind, introduce percentage-based coefficient struct members and use them in the calculations. One thing to note is that the IB coefficient is inverse (100/ib_percent) which feels a bit backwards, but it's necessary for precision..

2023-08-22interconnect: Add debugfs test clientMike Tipton4-1/+173
It's often useful during test, debug, and development to issue path votes from shell. Add a debugfs client for this purpose. Example usage: cd /sys/kernel/debug/interconnect/test-client/ # Configure node endpoints for the path from CPU to DDR on # qcom/sm8550. echo chm_apps > src_node echo ebi > dst_node # Get path between src_node and dst_node. This is only # necessary after updating the node endpoints. echo 1 > get # Set desired BW to 1GBps avg and 2GBps peak. echo 1000000 > avg_bw echo 2000000 > peak_bw # Vote for avg_bw and peak_bw on the latest path from "get". # Voting for multiple paths is possible by repeating this # process for different nodes endpoints. echo 1 > commit Allowing userspace to directly enable and set bus rates can be dangerous So, following in the footsteps of the regmap [0] and clk [1] frameworks, keep these userspace controls compile-time disabled without Kconfig options to enable them. Enabling this will require code changes to define INTERCONNECT_ALLOW_WRITE_DEBUGFS.
