This offset only works for some SoCs like SDM845 for which driver support was initially added. But the later SoCs use different register stride that vary between the banks with holes in-between. So it is not possible to use a single register stride for accessing the CSRs of each bank. By doing so could result in a crash with the current drivers. So far this crash is not reported since EDAC_QCOM driver is not enabled in ARM64 defconfig and no one tested the driver extensively by triggering the EDAC IRQ (that's where each bank CSRs are accessed). For fixing this issue, let's obtain the base address of each LLCC bank from devicetree and get rid of the fixed stride. This series has been tested on SM8250, SM8450, SM6350, SC8280XP, SA8540P, and SDM845. Merging strategy ---------------- Patches 1/17, 2/17 and 3/17 can be merged independently to EDAC tree. Rest of the patches should be merged to qcom tree due to LLCC dependency. Thanks, Mani Changes in v5: * Reduced the size of llcc0 to 0x45000 on SDM845 due to overlapping with BWMON * Added a patch to disable creation of EDAC platform device on SDM845 * Rebase on top of v6.2-rc1 * Moved the EDAC specific patches to the start so that they can be applied independently of LLCC patches Changes in v4: * Added a patch that fixes the use-after-free bug in qcom_edac driver Changes in v3: * Brought back reg-names property for compatibility (Krzysztof) * Removed Fixes tag and stable list as backporting the drivers/binding/dts patches alone would break (Krzysztof) * Fixed the uninitialized variable issue (Kbot) * Added a patch to make use of driver supplied polling interval (Luca) * Added a patch for module autoloading (Andrew) * Didn't collect Review tags from Sai as the dts patches were changed. Changes in v2: * Removed reg-names property and used index of reg property to parse LLCC bank base address (Bjorn) * Collected Ack from Sai for binding * Added a new patch for polling mode (Luca) * Renamed subject of patches targeting SC7180 and SM6350 Manivannan Sadhasivam (17): EDAC/device: Make use of poll_msec value in edac_device_ctl_info struct EDAC/qcom: Add platform_device_id table for module autoloading EDAC/qcom: Do not pass llcc_driv_data as edac_device_ctl_info's pvt_info dt-bindings: arm: msm: Update the maintainers for LLCC dt-bindings: arm: msm: Fix register regions used for LLCC banks arm64: dts: qcom: sdm845: Fix the base addresses of LLCC banks arm64: dts: qcom: sc7180: Fix the base addresses of LLCC banks arm64: dts: qcom: sc7280: Fix the base addresses of LLCC banks arm64: dts: qcom: sc8280xp: Fix the base addresses of LLCC banks arm64: dts: qcom: sm8150: Fix the base addresses of LLCC banks arm64: dts: qcom: sm8250: Fix the base addresses of LLCC banks arm64: dts: qcom: sm8350: Fix the base addresses of LLCC banks arm64: dts: qcom: sm8450: Fix the base addresses of LLCC banks arm64: dts: qcom: sm6350: Fix the base addresses of LLCC banks qcom: llcc/edac: Fix the base address used for accessing LLCC banks qcom: llcc/edac: Support polling mode for ECC handling soc: qcom: llcc: Do not create EDAC platform device on SDM845 .../bindings/arm/msm/qcom,llcc.yaml | 128 ++++++++++++++++-- arch/arm64/boot/dts/qcom/sc7180.dtsi | 2 +- arch/arm64/boot/dts/qcom/sc7280.dtsi | 5 +- arch/arm64/boot/dts/qcom/sc8280xp.dtsi | 10 +- arch/arm64/boot/dts/qcom/sdm845.dtsi | 7 +- arch/arm64/boot/dts/qcom/sm6350.dtsi | 2 +- arch/arm64/boot/dts/qcom/sm8150.dtsi | 7 +- arch/arm64/boot/dts/qcom/sm8250.dtsi | 7 +- arch/arm64/boot/dts/qcom/sm8350.dtsi | 7 +- arch/arm64/boot/dts/qcom/sm8450.dtsi | 7 +- drivers/edac/edac_device.c | 2 +- drivers/edac/qcom_edac.c | 63 +++++---- drivers/soc/qcom/llcc-qcom.c | 80 ++++++----- include/linux/soc/qcom/llcc-qcom.h | 6 +- 14 files changed, 244 insertions(+), 89 deletions(-)
