[PATCH OLK-6.6 0/2] soc cache: Add support for HiSilicon L3 cache
by Yushan Wang 16 Apr '25

16 Apr '25

driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IC15TR ---------------------------------------------------------------------- This series adds support for HiSilicon SoC cache lockdown and cache maintenance operations. Cache lockdown feature prevents cache entries from being evicted from L3 cache. It can be enabled by calling mmap function to the file (`/dev/hisi_soc_cache_mgmt`). This feature is implemented in the driver hisi_soc_l3c. Cache maintenance feature, following Arm64's CHI spec[1], enables users to raise certain transactions to the memory residing in the cache. This can be achieved by calling ioctl function to the same file as above. This feature is implemented in the driver hisi_soc_hha. L3 cache and L3 cache PMU share the same memory resource, which makes one fails to probe while another is on board. Since both devices rely on distinct information exported by ACPI, their probing functions should be unrelated. Workaround the resource conflict check by replacing devm_ioremap_resource() to devm_ioremap() instead.
