soc: qcom: llcc: Update the SCT table for IPQ5424

2026-08-31T16:30:50+00:00

Update the IPQ5424 LLCC slice configuration table to give the PPE and Wi-Fi datapaths dedicated slices. Assign slice IDs 1 and 5 to the PPE RX descriptor and RX fill use cases, slice IDs 6 and 7 to the Wi-Fi radios connected over PCIe, and slice ID 2 to the CPU subsystem. Adjust the corresponding capacities, priorities, and way masks for these consumers. These slice assignments are based on recommendations from the performance team, following throughput measurements on IPQ5424. Having the dedicated slice configuration for each of these use cases helps to improve the networking throughput by more than 1 Gbps. Rename the usecase IDs for slice IDs 1 and 2 because LLCC_CPUSS and LLCC_VIDSC0 do not describe the actual users of those slices.

soc: qcom: llcc-qcom: get SCT descriptors from fw-populated memory

2026-05-13T16:45:57+00:00

Retrieve System Cache Table (SCT) descriptors from a shared memory region populated by firmware. SCT initialization and programming are performed entirely by firmware outside of Linux. The LLCC driver only consumes the pre-initialized descriptor data and does not configure SCT itself. Support this mechanism for future SoCs that provide SCT programming via firmware.

soc: qcom: llcc: Add per-slice counter and common llcc slice descriptor

2026-03-16T01:33:55+00:00

Fix incorrect slice activation/deactivation accounting by replacing the bitmap-based activation tracking with per-slice atomic reference counters. This resolves mismatches that occur when multiple client drivers vote for the same slice or when llcc_slice_getd() is called multiple times. As part of this fix, simplify slice descriptor handling by eliminating dynamic allocation. llcc_slice_getd() now returns a pointer to a preallocated descriptor, removing the need for repeated allocation/free cycles and ensuring consistent reference tracking across all users.

EDAC/qcom: Make irq configuration optional

2024-10-06T03:17:08+00:00

On most modern qualcomm SoCs, the configuration necessary to enable the Tag/Data RAM related irqs being propagated to the SoC irq controller is already done in firmware (in DSF or 'DDR System Firmware') On some like the x1e80100, these registers aren't even accesible to the kernel causing a crash when edac device is probed. Hence, make the irq configuration optional in the driver and mark x1e80100 as the SoC on which this should be avoided.
