The platforms based on SDM845 SoC locks the access to EDAC registers in the bootloader. So probing the EDAC driver will result in a crash. Hence, disable the creation of EDAC platform device on all SDM845 devices. The issue has been observed on Lenovo Yoga C630 and DB845c. While at it, also sort the members of `struct qcom_llcc_config` to avoid any holes in-between.

Not all Qcom platforms support IRQ mode for ECC handling. For those platforms, the current EDAC driver will not be probed due to missing ECC IRQ in devicetree. So add support for polling mode so that the EDAC driver can be used on all Qcom platforms supporting LLCC. The polling delay of 5000ms is chosen based on Qcom downstream/vendor driver.

2023-03-15qcom: llcc/edac: Fix the base address used for accessing LLCC banksManivannan Sadhasivam
The Qualcomm LLCC/EDAC drivers were using a fixed register stride for accessing the (Control and Status Registers) CSRs of each LLCC bank. This stride 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. For fixing this issue, let's obtain the base address of each LLCC bank from devicetree and get rid of the fixed stride. This also means, there is no need to rely on reg-names property and the base addresses can be obtained using the index. First index is LLCC bank 0 and last index is LLCC broadcast. If the SoC supports more than one bank, then those need to be defined in devicetree for index from 1..N-1.

2023-03-06soc: qcom: llcc: Fix slice configuration values for SC8280XPAbel Vesa
The slice IDs for CVPFW, CPUSS1 and CPUWHT currently overflow the 32bit LLCC config registers, which means it is writing beyond the upper limit of the ATTR0_CFGn and ATTR1_CFGn range of registers. But the most obvious impact is the fact that the mentioned slices do not get configured at all, which will result in reduced performance. Fix that by using the slice ID values taken from the latest LLCC SC table.

2022-08-29soc: qcom: llcc: Pass LLCC version based register offsets to EDAC driverManivannan Sadhasivam
The LLCC EDAC register offsets varies between each SoCs. Until now, the EDAC driver used the hardcoded register offsets. But this caused crash on SM8450 SoC where the register offsets has been changed. So to avoid this crash and also to make it easy to accommodate changes for new SoCs, let's pass the LLCC version specific register offsets to the EDAC driver. Currently, two set of offsets are used. One is starting from LLCC version v1.0.0 used by all SoCs other than SM8450. For SM8450, LLCC version starting from v2.1.0 is used.

2022-08-29soc: qcom: llcc: Rename reg_offset structs to reflect LLCC versionManivannan Sadhasivam
The register offsets used by the LLCC block retains its layout for multiple versions. For instance, starting from version v1.0.0 to v2.0.1 the offsets are same. And starting from v2.1.0, the offsets changed. But the current reg_offset naming convention is confusing. So to reflect this change correctly in driver, let's encode the start version from which the offsets got changed in reg_offset struct name. This will be llcc_v1_reg_offset for v1.0.0 and llcc_v2_1_reg_offset for v2.1.0. This will allow multiple SoCs to use the same reg_offset clearly. And in the future if the offsets got changed again, then that specific version could be encoded in the struct name.

Several features in newer LLCC HW are based on the full version rather than just major or minor versions such as write-subcache enable which is applicable for versions v2.0.0.0 and later, also upcoming write-subcache cacheable for SM8450 SoC which is only present in versions v2.1.0.0 and later, so it makes it easier and cleaner to just directly compare with the full version than adding additional major/branch/ minor/echo version checks.

2020-10-26soc: qcom: llcc: Support chipsets that can write to llccIsaac J. Manjarres
Older chipsets may not be allowed to configure certain LLCC registers as that is handled by the secure side software. However, this is not the case for newer chipsets and they must configure these registers according to the contents of the SCT table, while keeping in mind that older targets may not have these capabilities. So add support to allow such configuration of registers to enable capacity based allocation and power collapse retention for capable chipsets. Reason for choosing capacity based allocation rather than the default way based allocation is because capacity based allocation allows more finer grain partition and provides more flexibility in configuration. As for the retention through power collapse, it has an advantage where the cache hits are more when we wake up from power collapse although it does burn more power but the exact power numbers are not known at the moment.

This makes way for adding future llcc versions. Also pull out the llcc-qcom specific definitions from includes. Includes path now contains the only definitions that are to be exposed to other subsystems.

The cleaning up was done without changing the driver file name to ensure a cleaner bisect. Change the file name now to facilitate making the driver generic in subsequent patch. Signed-off-by: Vivek Gautam <vivek.gautam@codeaurora.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
