STRUCT PVR_PAGE_FLAGS_RAW(9)
π struct pvr_page_flags_raw(9) β a Kernel API Manual moment
okay bestie, buckle up, because we're looking at struct pvr_page_flags_raw β literally the configurable flags from a single entry in a level 0 page table. that's it, that's the whole vibe. it's the flag-girl of the level 0 page table world π
β¨ NAME β¨
struct pvr_page_flags_raw β the configurable flags pulled out of one single entry in a level 0 page table. yes, level zero. the baby level. iconic behavior honestly π
πΈ SYNOPSIS πΈ
struct pvr_page_flags_raw {
struct pvr_page_table_l0_entry_raw val;
};
π¦ Members π¦
valβ the raw value of these flags, no cap. and listen: since these flags are a strict subset ofstruct pvr_page_table_l0_entry_raw, you use that type for our member here. strict subset means strict. respect the hierarchy π
π Description π
so the flags living inside this type are, in order:
- PM/FW Protect β bit 62
- SLC Bypass Control β bit 3
- Cache Coherency β bit 2
- Read Only β bit 1
that's bits 62, 3, 2 and 1 respectively, for the record. not alphabetical, not sequential, just how it is. slay π
β οΈ do NOT instantiate this type directly. like, ever. fr fr. instead usepvr_page_flags_raw_createso you can be sure only valid bits ofvalare set. it's giving "let the function handle it" and honestly the function should handle it π
