| * soc: sifive: ccache: Rename SiFive L2 cache to Composable cache.Greentime Hu2022-10-132-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since composable cache may be L3 cache if there is a L2 cache, we should use its original name composable cache to prevent confusion. There are some new lines were generated due to adding the compatible "sifive,ccache0" into ID table and indent requirement. The sifive L2 has been renamed to sifive CCACHE, EDAC driver needs to apply the change as well.

| * | EDAC/i10nm: Add driver decoder for Ice Lake and Tremont CPUsYouquan Song2022-09-083-2/+138
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current i10nm_edac only supports firmware decoder (ACPI DSM methods). MCA bank registers of Ice Lake or Tremont CPUs contain the information to decode DDR memory errors. To get better decoding performance, add the driver decoder (decoding DDR memory errors via extracting error information from MCA bank registers) for Ice Lake and Tremont CPUs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The performance of driver decoder[1] is better than the performance of firmware decoder[2], especially on frequent correctable errors. So use the driver decoder first, fall back to firmware decoder if the driver decoder is unavailable. Also rename the function pointer skx_decode to driver_decode (better name to contrast with adxl_decode).

However, the init_amd_nbs() initcall already does call amd_cache_northbridges() unconditionally and thus makes sure the NB descriptors are enumerated. That initcall is a fs_initcall type which is on the 5th group (starting from 0) of initcalls that gets run in increasing numerical order by the init code. The module_init() call is turned into an __initcall() in the MODULE=n case and those are device-level initcalls, i.e., group 6. Therefore, the northbridges caching is already finished by the time module initialization starts and thus the correct initialization order is retained. Unexport amd_cache_northbridges(), update dependent modules to call amd_nb_num() instead. While at it, simplify the checks in amd_cache_northbridges().
