The kernel then reports failure to reserve the region and +subsequent EFI runtime activity may trigger aborts. + +The remote heap node was described as a fixed "no-map" region, which +turns it into a hard carveout. Replace it with a "shared-dma-pool" +reserved memory region with reusable CMA-backed allocation, specifying +alignment and size. + +This avoids hard carveouts and reduces the chance of conflicting with +firmware memory maps while keeping an explicit pool for ADSP remote +heap usage. + +Fixes: 90a58ffa9c55 ("arm64: dts: qcom: kodiak: Add memory region for audiopd") +Cc: stable@kernel.org +Signed-off-by: Jianping Li <jianping.li@oss.qualcomm.com> +Reviewed-by: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com> +Link: https://lore.kernel.org/r/20260429073443.2027-1-jianping.li@oss.qualcomm.com +Signed-off-by: Bjorn Andersson <andersson@kernel.org> +--- + arch/arm64/boot/dts/qcom/kodiak.dtsi | 9 ++++++--- + 1 file changed, 6 insertions(+), 3 deletions(-) + +diff --git a/arch/arm64/boot/dts/qcom/kodiak.dtsi b/arch/arm64/boot/dts/qcom/kodiak.dtsi +index ac048ec9aeb5..7e73348fe0d0 100644 +--- a/arch/arm64/boot/dts/qcom/kodiak.dtsi ++++ b/arch/arm64/boot/dts/qcom/kodiak.dtsi +@@ -191,9 +191,12 @@ rmtfs_mem: rmtfs@9c900000 { + qcom,vmid = <QCOM_SCM_VMID_MSS_MSA>; + }; + +- adsp_rpc_remote_heap_mem: adsp-rpc-remote-heap@9cb80000 { +- reg = <0x0 0x9cb80000 0x0 0x800000>; +- no-map; ++ adsp_rpc_remote_heap_mem: adsp-rpc-remote-heap { ++ compatible = "shared-dma-pool"; ++ alloc-ranges = <0x0 0x80000000 0x0 0x80000000>; ++ reusable; ++ alignment = <0x0 0x400000>; ++ size = <0x0 0x800000>; + }; + }; + +-- +2.55.0 + |
