The .fixed section is guaranteed to appear at a +/// fixed offset from the beginning of the image, containing data required to +/// be manipulated when images are resident in non-volatile memories, thereby +/// avoiding having to search the TOC. Data manipulated during in-memory image +/// processing can always be easily located using the SBE-XIP TOC APIs. All +/// of the data stored in .fixed can also still be referenced via the SBE-XIP +/// TOC. +/// +/// This header file can be #include-ed into either C or SBE assembly language +/// source code. In C, it creates simple structures 'ProcChipAttributes', +/// 'PervAttributes', 'CoreAttributes', 'EQAttributes' and 'EXAttributes' that +/// contain attribute information that are sized per XML definition per entry. +/// +/// PPE image data is always stored big-endian, so applications on little-endian +/// hosts will need to perform the appropriate endian converison when reading or +/// writing images via this header. +/// +/// In assembler code, this header creates macros '.proc_sbe_fixed_proc_chip', +/// '.proc_sbe_fixed_perv', '.proc_sbe_fixed_core', '.proc_sbe_fixed_ex', +/// '.proc_sbe_fixed_eq', that is expanded exactly once in the file +/// 'sbe_base_header.S', creating the actual data allocation of the data +/// equivalent to the C structure. Assembler code references the data symbols +/// as normal. +/// +/// To simplify programming a 'mini-TOC' is also provided for this data in +/// the .fixed_toc section. This section is comprised of SbeXipHashedToc +/// structures. When a symbol is indedxed in .fixed, a blank SbeXipHashedToc +/// stucture is added to .fixed_toc. During image normalization the array of +/// SbeXipHashedToc is filled in as each symbol in .fixed is re-indexed into +/// .fixed_toc. + +#ifndef __PROC_SBE_FIXED_H__ +#define __PROC_SBE_FIXED_H__ + +#include "p9_sbe.H" +#include "plat_target_parms.H" +#include "fapi2AttributeIds.H" + +#ifdef __ASSEMBLER__ + .macro .proc_sbe_fixed_system + .section .fixed, "a", @progbits + .balign 8 + .global G_system_attributes +G_system_attributes: +#else + +extern "C" { +namespace fapi2attr { +typedef struct SystemAttributes_t { +#endif + +#include "proc_sbe_fixed_system.H" + +#ifdef __ASSEMBLER__ + .endm +#else +} SystemAttributes; +} // fapi2 +} // C +#endif + +#ifdef __ASSEMBLER__ + .macro .proc_sbe_fixed_proc_chip + .section .fixed, "a", @progbits + .balign 8 + .global G_proc_chip_attributes +G_proc_chip_attributes: +#else + +extern "C" { +namespace fapi2attr { +typedef struct ProcChipAttributes_t { +#endif + +#include "proc_sbe_fixed_proc_chip.H" + +#ifdef __ASSEMBLER__ + .endm +#else +} ProcChipAttributes; +} // fapi2 +} // C +#endif + +/// +/// Pervasive Target Attributes +#ifdef __ASSEMBLER__ + .macro .proc_sbe_fixed_perv + .section .fixed, "a", @progbits + .balign 8 + .global G_perv_attributes +G_perv_attributes: +#else +namespace fapi2attr { +typedef struct PervAttributes_t { +#endif + +#include "proc_sbe_fixed_perv.H" + +#ifdef __ASSEMBLER__ + .endm +#else +} PervAttributes; +} // fapi2 +#endif + +/// +/// Core (EC) Target Attributes +#ifdef __ASSEMBLER__ + .macro .proc_sbe_fixed_core + .section .fixed, "a", @progbits + .balign 8 + .global G_core_attributes +G_core_attributes: +#else +namespace fapi2attr { +typedef struct CoreAttributes_t { +#endif + +#include "proc_sbe_fixed_core.H" + +#ifdef __ASSEMBLER__ + .endm +#else +} CoreAttributes; +} // fapi2 +#endif + +/// +/// EX Target Attributes +#ifdef __ASSEMBLER__ + .macro .proc_sbe_fixed_ex + .section .fixed, "a", @progbits + .balign 8 + .global G_ex_attributes +G_ex_attributes: +#else +namespace fapi2attr { +typedef struct EXAttributes_t { +#endif + +#include "proc_sbe_fixed_ex.H" + +#ifdef __ASSEMBLER__ + .endm +#else +} EXAttributes; +} // fapi2 +#endif + +/// +/// EQ Target Attributes +#ifdef __ASSEMBLER__ + .macro .proc_sbe_fixed_eq + .section .fixed, "a", @progbits + .balign 8 + .global G_eq_attributes +G_eq_attributes: +#else +namespace fapi2attr { +typedef struct EQAttributes_t { +#endif + +#include "proc_sbe_fixed_eq.H" + +#ifdef __ASSEMBLER__ + .endm +#else +} EQAttributes; +} // fapi2 +#endif + + +#endif // __PROC_SBE_FIXED_H__ |
