Qalisa kabusha i-Linux

Njengesibonelo esithileampkulokhu, ku-Linux, umyalo wokuvala shaqa usetshenziselwa ukumisa noma ukuqalisa kabusha uhlelo. Umyalo uvamise ukuba neziteketiso eziningi, okungukuthi misa, ukucisha, nokuqalisa kabusha. Lezi ziteketiso zicacisa ukuthi kufanele kumiswe umshini lapho uvala shaqa, ucime umshini lapho uvala shaqa, noma uqalise kabusha umshini lapho uvala shaqa.

Le miyalo yendawo yomsebenzisi ikhipha ikholi yesistimu yokuqalisa kabusha eya ku-Linux, ebanjelwe i-kernel futhi yasebenza ku-ecall ye-SBI.
Kunamaleveli ahlukahlukene okuqalisa kabusha - REBOOT_WARM, REBOOT_COLD, REBOOT_HARD - lezi zingadluliswa njengezimpikiswano zomugqa womyalo ku-kernel (ngokwesibonelo.ample, qala kabusha=w[arm] ye-REBOOT_WARM). Ukuze uthole ulwazi olwengeziwe ngekhodi yomthombo we-Linux kernel, bheka Amadokhumenti/admin-guide/kernel-paramters.txt.
Kungenjalo, uma i-/sys/kernel/reboot inikwe amandla, izibambi ezingaphansi zingafundwa ukuze kutholwe ukucushwa kwesistimu yamanje, futhi kubhalwe ukuyishintsha. Ukuze uthole ulwazi olwengeziwe ngekhodi yomthombo we-Linux kernel, bheka Amadokhumenti/ABI/testing/sysfs-kernel-reboot.

Izinja ezigadayo

Omunye umqondo ohlobene nokuqalwa kabusha kwesistimu kanye nokuqaliswa kabusha kwesistimu yilowo wokuthola kabusha uhlelo lapho kudutshulwa isibali sikhathi se-watchdog. Izibali-sikhathi ze-Watchdog zisetshenziswa kakhulu ezinhlelweni ezishumekiwe ukuze zilulame ngokuzenzakalelayo emaphutheni ezingxenyekazi zekhompuyutha zesikhashana, kanye nokuvikela isoftware engalungile noma engalungile ukuthi iphazamise ukusebenza kwesistimu.
I-PIC64GX ifaka phakathi ukwesekwa kwe-hardware watchdog ukuze kuqashwe izindwane ngazinye lapho uhlelo lusebenza. Abaqaphi baqinisekisa ukuthi ama-harts angaqalwa kabusha uma engaphenduli ngenxa yamaphutha esoftware angalungiseki.
I-PIC64GX ihlanganisa izimo ezinhlanu zamabhulokhi wehadiwe we-watchdog timer asetshenziselwa ukuthola ukukhiya kwesistimu -okukodwa kwehart ngayinye. Ukwenza lula ukuxutshwa kwe-Asymmetric Multi-Processing (AMP) umsebenzi omningi, i-HSS isekela ukuqapha kanye nokusabela ekudubuleni kwezinja.

Idatha ye-PIC64GX

I-HSS inomthwalo wemfanelo wokuqalisa kabusha ama-harts ohlelo lokusebenza ngamandla-up, kanye nokuwaqalisa kabusha (ngawodwa noma ngokuhlanganyela) kunoma yisiphi isigaba.tage, uma idingeka noma ifunwa. Njengomphumela walokhu, ukusabela kumicimbi ye-watchdog ku-PIC64GX isingathwa yi-HSS.
Imonitha 'ye-virtual watchdog' isetshenziswa njengesevisi yomshini kahulumeni we-HSS, futhi izibopho zayo ukuqapha isimo se-U54 yokuqapha izingxenyekazi zehadiwe ngayinye. Uma enye yalezi zinja ze-U54 ivakashela, i-HSS ithola lokhu futhi izoqalisa kabusha i-U54 ngokufanele. Uma i-U54 iyingxenye yomongo we-SMP, wonke umongo ucatshangelwa ukuthi uqalise kabusha, njengoba umongo unelungelo lokuqalisa kabusha okufudumele. Lonke uhlelo luzoqalwa kabusha uma umongo unelungelo lokuqalisa kabusha okubandayo.

Izinketho ze-Kconfig Efanelekayo

Ukusekelwa kwe-Watchdog kufakwe ngokuzenzakalela ekwakhiweni kwe-HSS ekhishwe. Uma ufisa ukwakha i-HSS yangokwezifiso, lesi sigaba sizochaza indlela yokumisa ukuze uqinisekise ukuthi ukusekelwa kwe-Watchdog kunikwe amandla.

I-HSS icushwe kusetshenziswa isistimu yokumisa ye-Kconfig. I-toplevel .config file edingekayo ukuze ukhethe ukuthi yiziphi izinsizakalo ezihlanganiswa ngaphakathi noma ngaphandle kwesakhiwo se-HSS.
Okokuqala, inketho yezinga eliphezulu CONFIG_SERVICE_WDOG idinga ukuvulwa (“Usekelo lwe-Virtual Watchdog” ngokwenza ukulungiselelwa).

Lokhu bese kuveza okukhethwa kukho okulandelayo okuncike ekusekelweni kwe-Watchdog:

CONFIG_SERVICE_WD OG_DEBUG
Inika amandla usekelo lwemilayezo yolwazi/yokulungisa iphutha evela kusevisi ye-virtual watchdog.
CONFIG_SERVICE_WD OG_DEBUG_TIMEOUT_SECS
Inquma ubude besikhathi (ngemizuzwana) lapho imilayezo yokususa iphutha ye-Watchdog izokhishwa yi-HSS.
CONFIG_SERVICE_WD OG_ENABLE_E51
Inika amandla i-watchdog yenhliziyo yokuqapha i-E51 ngaphezu kwama-U54s, ivikela ukusebenza kwe-HSS ngokwayo.

Uma i-watchdog ye-E51 ivuliwe, i-HSS izobhalela i-Watchdog ngezikhathi ezithile ukuze iyivuselele futhi ivimbele ukuthi ingadubuli. Uma, ngesizathu esithile, inhliziyo ye-E51 ikhiya noma iphahlazeka futhi i-watchdog ye-E51 inikwe amandla, lokhu kuzohlala kusetha kabusha lonke uhlelo.

I-Watchdog Operation
I-watchdog hardware isebenzisa izinto zokubala eziphansi. Iwindi elinqatshelwe ukuvuselela lingadalwa ngokumisa i-watchdog Inani eliphakeme kakhulu lapho Ukuvuselela Kuvunyelwe (MVRP).

Uma inani lamanje lesibali sikhathi se-watchdog likhulu kunevelu ye-MVRP, ukuvuselela inja yokuqapha akuvunyelwe. Ukuzama ukuvuselela isibali-sikhathi se-watchdog efasiteleni elinqatshelwe kuzodinga ukuphazamiseka kokuvala.

Ukuvuselela i-watchdog phakathi kwevelu ye-MVRP kanye ne-Trigger Value (TRIG) kuzovuselela ngempumelelo ikhawunta futhi kuvimbele inja ekudubuleni.
Uma inani lesibali sikhathi se-watchdog libala ngaphansi kwevelu ye-TRIG, inja yokubuka izodubula.

I-Watchdog State Machine

Umshini wombuso we-watchdog uqonde kakhulu - uqala ngokulungiselela i-watchdog ye-E51, uma inikwe amandla, bese uhamba esimweni sokungenzi lutho ukuya ekuqapheni. Isikhathi ngasinye lapho kuzungeza i-superloop, lesi simo sokuqapha siyacelwa, esihlola isimo se-watchdog ngayinye ye-U54.

Umshini we-watchdog state uxhumana nomshini we-boot state ukuze uqalise kabusha i-hart (kanye nanoma yiziphi ezinye izigqoko ezikusethi yayo ye-boot), uma ithola ukuthi i-hart ayikwazanga ukuvuselela inja yayo ngesikhathi.

Imodi yokukhiya

Ngokuvamile (ikakhulukazi nge AMP izicelo), kulindeleke ukuthi i-HSS ihlale kumodi ye-M, ku-U54, ukuze ivumele ukuqalisa kabusha kokuqukethwe ngakunye (okungukuthi, qala kabusha umongo owodwa kuphela, ngaphandle kokuqalisa kabusha kwe-chip egcwele), kanye nokuvumela i-HSS ukuthi iqaphe ezempilo (ECCs, Izingcezu Zesimo Sokhiye, Amaphutha Ebhasi, amaphutha e-SBI, ukwephulwa kwe-PMP, njll).

Ukuze unikeze amandla okuqalisa kabusha ku- per-AMP isisekelo somongo (ngaphandle kokudinga lonke uhlelo ukuthi luqalise kabusha), i-E51 imvamisa inelungelo lokufinyelela inkumbulo kuso sonke isikhala sememori sohlelo. Nokho, kungase kube nezimo lapho lokhu kungafiseleki khona, futhi ikhasimende lingase likhethe ukukhawulela okwenziwa i-firmware ye-E51 HSS uma uhlelo seluqaliswe ngempumelelo.

hss-payload-generator
Ithuluzi le-HSS Payload Generator lidala isithombe esifomethiwe sokulayisha okukhokhelwayo se-Hart Software Service zero-stage-bootloader ku-PIC64GX, inikezwe ukucushwa file kanye nesethi ye-ELF files kanye/noma kanambambili. Ukucushwa file isetshenziselwa ukwenza imephu enambambili be-ELF noma ama-blob kanambambili ku-harts ngayinye yohlelo lokusebenza (U54s).

Umfanekiso B.14. I-hss-payload-generator Flow

Ithuluzi lenza ukuhlola kwengqondo okuyisisekelo esakhiweni sokucushwa file ngokwayo kanye nasezithombeni ze-ELF. Izithombe ze-ELF kufanele zibe ezisebenzisekayo ze-RISC-V.

Example Run

Ukuze usebenzise ithuluzi le-hss-payload-generator nge-sample ukumisa file kanye ne-ELF files:
$ ./hss-payload-generator -c test/config.yaml output.bin
Ukuze uphrinte ukuxilonga mayelana nesithombe esivele sikhona, sebenzisa:
$ ./hss-payload-generator -d output.bin

Ukuze unike amandla ukuqinisekiswa kwe-boot okuvikelekile (ngokusayina isithombe), sebenzisa -p ukuze ucacise indawo yokhiye oyimfihlo we-X.509 we-Elliptic Curve P-384 (SECP384r1):
$ ./hss-payload-generator -c test/config.yaml payload.bin -p /path/to/private.pem

Ukuze uthole ulwazi olwengeziwe, bheka imibhalo yokuqinisekisa i-Secure Boot.

Lungiselela File Example

Okokuqala, ngokuzikhethela singasetha igama lesithombe sethu, ngaphandle kwalokho, esisodwa sizodalwa ngamandla:
set-name: 'PIC64-HSS::TestImage'
Okulandelayo, sizochaza amakheli ezindawo zokungena zenhliziyo ngayinye, kanje:
hart-entry-points: {u54_1: ‘0x80200000’, u54_2: ‘0x80200000’, u54_3: ‘0xB0000000′, u54_4:’0x80200000’}

Izithombe zomthombo we-ELF zingacacisa indawo yokungena, kodwa sifuna ukwazi ukusekela amaphuzu esibili okungena kumahart uma kudingeka, ngokwesibonelo.ampfuthi, uma amahart amaningi ehloselwe ukuqalisa isithombe esifanayo, angase abe namaphoyinti okungena angawodwana. Ukuze sisekele lokhu, sicacisa amakheli ezindawo zokungena ekucushweni file uqobo.

Manje sesingakwazi ukuchaza ezinye izinkokhelo (umthombo ELF files, noma amabhulobhu anambambili) azobekwa ezindaweni ezithile enkumbulweni. Isigaba somthwalo okhokhelwayo sichazwa ngegama elingukhiye elithi payloads, bese kuba nenani lezincazelo zomthwalo wokukhokha ngazinye. Umthwalo ngamunye okhokhelwayo unegama (indlela eya kuwo file), i- owner-hart, kanye ne-hart engu-1 kuya kwezi-3.

Ukwengeza, umthwalo okhokhelwayo unemodi yelungelo lapho uzoqala khona ukusebenza. Izindlela zamalungelo avumelekile i-PRV_M, i-PRV_S ne-PRV_U, lapho lezi zichazwa ngokuthi:

Imodi yomshini ye-PRV_M
Imodi yomphathi we-PRV_S
I-PRV_U Imodi yomsebenzisi

Esihlokweni esilandelayoample:

test/zephyr.elf kucatshangwa ukuthi uhlelo lokusebenza lwe-Zephyr olusebenza ngo-U54_3, futhi lulindele ukuqala kumodi yelungelo le-PRV_M.
test/u-boot-dtb.bin wuhlelo lwe-Das U-Boot bootloader, futhi lusebenza ku-U54_1, U54_2 naku-U54_4. Ilindele ukuqala kumodi yelungelo le-PRV_S.

Okubalulekile:
Ukukhishwa kwe-U-Boot kudala i-ELF file, kodwa ngokuvamile ayilungiseleli isandiso se-.elf. Kulokhu, unambambili odalwe ngu-CONFIG_OF_SEPARATE uyasetshenziswa, owenezela ibhuloho lesihlahla sedivayisi kanambambili ye-U-Boot.

Nansi i-example Payloads ukucushwa file:

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

Okubalulekile:
Icala libalulekile kuphela file amagama ezindlela, hhayi amagama angukhiye. Ngakho-ke, isibonelo, i-u54_1 ibhekwa njengefana ne-U54_1, futhi i-exec-addr ibhekwa njengefana ne-EXEC-ADDR. Uma isandiso se-an.elf noma .bin sikhona, sidinga ukufakwa ekucushweni file.

Ngohlelo lwensimbi olungenalutho olungafuni ukukhathazeka nge-OpenSBI, inketho yokweqa-ivula, uma kuyiqiniso, izobangela ukulayishwa okukhokhelwa kuleyo nhliziyo kusetshenziswa i-mret elula kunalokho.
kunocingo lwe-OpenSBI sbi_init(). Lokhu kusho ukuthi inhliziyo izoqala ukusebenzisa ikhodi yensimbi engenalutho kungakhathaliseki ukuthi yikuphi ukucatshangelwa kwe-OpenSBI HSM. Qaphela ukuthi lokhu kusho ukuthi inhliziyo ayikwazi ukusebenzisa
icela ukunxenxa ukusebenza kwe-OpenSBI. Inketho yokweqa ingokuzithandela futhi ishintsha ibe amanga.

Ukuvumela ukuqalisa kabusha okufudumele komongo komunye umongo, singangeza inketho vumela ukuqalisa kabusha: fudumele. Ukuvumela ukuqalisa kabusha okubandayo komongo kwayo yonke isistimu, singangeza inketho yokuvumela ukuqalisa kabusha: kubanda. Ngokuzenzakalelayo, ngaphandle kokucacisa ukuvumela ukuqalisa phansi, umongo uvunyelwe kuphela ukuziqalisa kabusha okufudumele ngokwawo.
Kungenzeka futhi ukuhlobanisa idatha ehambisanayo nomthwalo ngamunye okhokhelwayo, isiboneloample, i-DeviceTree Blob (DTB) file, ngokucacisa idatha yokwengeza fileigama kanje:
test/u-boot.bin: {exec-addr: '0x80200000', owner-hart: u54_1, secondary-hart: u54_2, secondary-hart: u54_3, secondary-hart: u54_4, priv-mode: prv_s, ancilliary-data : test/pic64gx.dtb }
Le datha eyisilekeleli izofakwa kumthwalo okhokhelwayo (ubekwe ngokuqondile ngemva kwenhloko file kokusebenzisekayo
space), futhi ikheli layo lizodluliselwa ku-OpenSBI kunkambu elandelayo_arg1 (iphasiswe kurejista ye-$a1 esithombeni ngesikhathi sokuqalisa).

Ukuze uvimbele i-HSS ukuthi iqalise ngokuzenzakalela umongo (ngokwesibonelo, uma esikhundleni salokho sifuna ukunikeza ukulawula lokhu kumongo sisebenzisa i-remoteProc), sebenzisa ifulegi le-skip-autoboot:
test/zephyr.elf: {exec-addr: '0xB0000000', owner-hart: u54_3, priv-mode: prv_m, skip-opensbi: true, skip-autoboot: true}
Okokugcina, singakwazi ukukhetha ukubhala ngaphezulu amagama omthwalo ngamunye okhokhelwayo, sisebenzisa inketho yegama lokulayisha okukhokhelwayo. Okwesiboneloample:
test/u-boot.bin: {exec-addr: '0x80200000', owner-hart: u54_1, secondary-hart: u54_2, secondary-hart: u54_3, secondary-hart: u54_4, priv-mode: prv_s, ancilliary-data : test/pic64gx.dtb, payload-name: 'u-boot' }

Qaphela ukuthi abakhi be-Yocto kanye ne-Buildroot Linux bazokwakha, balungiselele, futhi baqhube i-hss-payload-
ijeneretha njengoba kudingeka ukukhiqiza izithombe zohlelo lokusebenza. Ukwengeza, i-pic64gx-curiosity-kit-amp okuqondiswe komshini ku-Yocto kuzokhiqiza isithombe sohlelo lokusebenza kusetshenziswa ithuluzi le-hss-payload-generator elibonisayo AMP, ne-Linux esebenza kumaharts angu-3 kanye ne-Zephyr egijima ku-hart engu-1.
