After several considerations, I decided to set VTV_PAGE_SIZE to 16KB under loongarch64.
v1 - > v2: 1. When the macro __loongarch_lp64 is defined, the VTV_PAGE_SIZE is set to 64K. 2. In the vtv_malloc.cc file __vtv_malloc_init function, it does not check whether VTV_PAGE_SIZE is equal to the system page size, if the macro __loongarch_lp64 is defined. v2 -> v3: Set VTV_PAGE_SIZE to 16KB under loongarch64. All regression tests of libvtv passed. === libvtv Summary === # of expected passes 176 ----------------------------------------- The loongarch64 kernel supports 4KB,16KB, or 64KB pages, but only 16k pages are currently supported in this code.
