Ata B.14. hss-payload-generator Flow

E fa'atino e le meafaigaluega ni su'esu'ega masani ile fa'atulagaina o le fa'atulagaga file ia lava ma luga o ata ELF. O ata ELF e tatau ona fa'atinoina RISC-V.

Example Taufetuli

• Ina ia fa'atino le meafaigaluega hss-payload-generator ma le sample configuration file ma ELF files:
  $ ./hss-payload-generator -c test/config.yaml output.bin
• Ina ia lolomi su'esu'ega e uiga i se ata sa iai muamua, fa'aoga:
  $ ./hss-payload-generator -d output.bin
• Ina ia mafai ona faʻamaonia le faʻamaonia o le taʻavale (e ala i ata saini), faʻaaoga -p e faʻamaonia ai le nofoaga o le X.509 Private Key mo le Elliptic Curve P-384 (SECP384r1):
  $ ./hss-payload-generator -c test/config.yaml payload.bin -p /path/to/private.pem

Mo nisi faʻamatalaga, vaʻai i le Secure Boot Authentication documentation.

Config File Example

• Muamua, e mafai ona tatou setiina se igoa mo la tatou ata, a leai, o le a faia le tasi ma le malosi:
  seti-igoa: 'PIC64-HSS::TestImage'
• Sosoo ai, o le a tatou faauigaina tuatusi nofoaga e ulufale ai mo fatu taitasi, e pei ona taua i lalo:
  hart-entry-points: {u54_1: ‘0x80200000’, u54_2: ‘0x80200000’, u54_3: ‘0xB0000000′, u54_4:’0x80200000’}

O ata fa'apogai a le ELF e mafai ona fa'amaoti mai ai se mea e ulufale ai, ae matou te manana'o ia mafai ona lagolago fa'ailoga lona lua mo 'o'o pe a mana'omia, mo le fa'aulu.ample, afai e tele hata e fa'amoemoe e fa'aa'e le ata lava e tasi, e mafai ona i ai ni togi ta'itasi. Ina ia lagolagoina lenei mea, matou te faʻamaoti tuatusi o mea e ulufale ai i le faʻatulagaga file lava ia.

Ua mafai nei ona matou faʻamatalaina nisi o totogi (puna ELF files, poʻo paʻu binary) o le a tuʻuina i nisi itulagi e manatua. O le vaega o le uta o loʻo faʻamatalaina i upu autu o totogi, ona sosoo ai lea ma se numera o faʻamatalaga totogi taʻitasi. O uta taitasi e iai lona igoa (ala i lona file), o se tagata e ona-hart, ma pe a filifili 1 i le 3 hata lona lua.

E le gata i lea, o se uta o loʻo i ai se tulaga faʻapitoa e amata ai le faʻatinoina. O tulaga fa'apitoa fa'apitoa o PRV_M, PRV_S ma PRV_U, o lo'o fa'amatalaina ai nei:

• PRV_M Faiga masini
• PRV_S Faiga Fa'atonu
• PRV_U Fa'aoga faiga

I le exampLe:

• test/zephyr.elf o loʻo faʻapea o se talosaga Zephyr e tamoʻe i U54_3, ma faʻamoemoe e amata i le PRV_M tulaga faʻapitoa.
• test/u-boot-dtb.bin o le Das U-Boot bootloader talosaga, ma e tamoe i luga o U54_1, U54_2 ma U54_4. E fa'amoemoe e amata ile PRV_S tulaga fa'apitoa.

Taua:
O le gaioiga a le U-Boot e fatuina ai se ELF file, ae masani lava e le faʻapipiʻiina le faʻaopoopoga .elf. I lenei tulaga, o le binary na faia e CONFIG_OF_SEPARATE o loʻo faʻaaogaina, lea e faʻapipiʻi ai se masini laau i le U-Boot binary.

O le ex leaample fa'atulagaina o Totogi file:

• test/zephyr.elf:
  {exec-addr: '0xB0000000', owner-hart: u54_3, priv-mode: prv_m, skip-opensbi: true}
• suega/u-boot-dtb.bin:
  {exec-addr: '0x80200000', owner-hart: u54_1, second-hart: u54_2, second-hart: u54_4,priv-mode: prv_s}

Taua:
O mataupu e taua mo le file igoa ala, ae le o upu autu. O lea, mo se faʻataʻitaʻiga, u54_1 e tutusa ma U54_1, ma exec-addr e tutusa ma EXEC-ADDR. Afai o loʻo iai le faʻaopoopoga o le .elf poʻo le .bin, e manaʻomia le faʻapipiʻiina i le faʻatulagaga file.

• Mo se talosaga uʻamea e le manaʻo e popole i le OpenSBI, o le filifiliga faaseʻe-tatala, pe a moni, o le a mafua ai ona faʻaogaina le uta i luga o lena fatu e faʻaaoga ai se mret faigofie.
  nai lo le OpenSBI sbi_init() valaau. O lona uiga o le fatu o le a amata ona faʻaogaina le faʻailoga uamea e tusa lava po o le a le OpenSBI HSM iloiloga. Manatua foi o lona uiga e le mafai e le fatu ona faaaoga
  vala'au e fa'aoga OpenSBI galuega. O le fa'ase'e-tatala filifiliga e filifili ma fa'aletonu ile sese.
• Ina ia fa'ataga le toe fa'afouina mafanafana o se isi fa'amatalaga, e mafai ona tatou fa'aopoopo le filifiliga fa'ataga le toe fa'afouina: mafanafana. Ina ia faʻatagaina se faʻamatalaga malulu toe faʻafouina o le polokalama atoa, e mafai ona matou faʻaopoopo le filifiliga faʻatagaina-toe faʻafou: malulu. Ona o le faaletonu, e aunoa ma le faamaotiina o le faataga-reboot, e na'o le anotusi e fa'atagaina e toe fa'amafanafanaina lava.
• E mafai fo'i ona fa'afeso'ota'i fa'amaumauga fa'atasi ma uta ta'itasi, mo se fa'ata'ita'igaample, o le DeviceTree Blob (DTB) file, e ala i le faʻamalamalamaina o faʻamatalaga faʻapitoa fileigoa e faapea:
  test/u-boot.bin: { exec-addr: '0x80200000', pule-hart: u54_1, lona lua-hart: u54_2, lona lua-hart: u54_3, lua-hart: u54_4, priv-mode: prv_s, ancilliary-data : test/pic64gx.dtb }
• O nei faʻamatalaga faʻaopoopo o le a aofia i totonu o le uta (tuʻu saʻo i tua o le autu file i le executable
  avanoa), ma o lona tuatusi o le a tuʻuina atu i OpenSBI i le isi_arg1 fanua (pasi i le $a1 resitala i le ata i le taimi o le taʻavale).
• Ina ia taofia le HSS mai le otometi ona faʻaosoina se tala (mo se faʻataʻitaʻiga, pe a matou mananaʻo e tuʻuina atu le puleaina o lenei mea i se faʻamatalaga e faʻaaoga ai le remoteProc), faʻaaoga le fuʻa skip-autoboot:
  test/zephyr.elf: {exec-addr: '0xB0000000', owner-hart: u54_3, priv-mode: prv_m, skip-opensbi: moni, skip-autoboot: moni}
• Ma le mea mulimuli, e mafai ona tatou filifili e faʻamalo igoa o totogi taʻitasi, e faʻaaoga ai le filifiliga totogi-igoa. Mo exampLe:
  test/u-boot.bin: { exec-addr: '0x80200000', pule-hart: u54_1, lona lua-hart: u54_2, lona lua-hart: u54_3, lua-hart: u54_4, priv-mode: prv_s, ancilliary-data : test/pic64gx.dtb, payload-name: 'u-boot' }

Manatua o le Yocto ma Buildroot Linux faufale o le a fausia, faʻapipiʻi, ma faʻatautaia le hss-payload-
generator pe'ā mana'omia e fa'atupu ai ata fa'aoga. E le gata i lea, o le pic64gx-curiosity-kit-amp masini fa'atatau i Yocto o le a fa'atupuina ai se ata talosaga e fa'aaoga ai le meafaigaluega hss-payload-generator e fa'aalia AMP, faʻatasi ai ma Linux o loʻo taʻavale i luga o le 3 harts ma Zephyr o loʻo tamoe i luga o le 1 hart.
