\u010c\u00ednska spolo\u010dnos\u0165 ByteDance, ktor\u00e1 vyv\u00edja slu\u017ebu TikTok, zverejnila v zozname pre v\u00fdvoj\u00e1rov jadra Linux z\u00e1platy s implement\u00e1ciou syst\u00e9mu Parker (PARtitioned KERnel), ktor\u00fd umo\u017e\u0148uje sp\u00fa\u0161\u0165a\u0165 na jednom po\u010d\u00edta\u010di naraz nieko\u013eko jadier Linux bez pou\u017eitia tradi\u010dnej virtualiz\u00e1cie. Z h\u013eadiska rie\u0161en\u00fdch \u00faloh Parker pripom\u00edna projekt Multikernel, ktor\u00fd bol predstaven\u00fd pred nieko\u013ek\u00fdmi d\u0148ami, ale l\u00ed\u0161i sa od neho architekt\u00farou a realiz\u00e1ciou. <\/p>\n

V Parker sa aplikuje sekcionovanie existuj\u00facich jadier CPU, pam\u00e4te a zariaden\u00ed. Ka\u017ed\u00fd sp\u00fa\u0161\u0165an\u00fd pr\u00edpad jadra vych\u00e1dza z jedn\u00e9ho spolo\u010dn\u00e9ho obrazu jadra, ale m\u00f4\u017ee vyu\u017e\u00edva\u0165 r\u00f4zne nastavenia a optimaliz\u00e1cie. Prv\u00e9 na\u010d\u00edtan\u00e9 jadro (Boot Kernel) vykon\u00e1va rozde\u013eovanie a sekcionovanie hardv\u00e9rov\u00fdch zariaden\u00ed. Ostatn\u00e9 in\u0161tancie jadra Linux (Application Kernel) funguj\u00fa len s priraden\u00fdmi jadrami CPU, pam\u00e4\u0165ou a zariadeniami vstupu\/v\u00fdstupu. <\/p>\n

Ako oblas\u0165 aplik\u00e1cie Parker sa spom\u00ednaj\u00fa po\u010d\u00edta\u010de s ve\u013ek\u00fdm po\u010dtom jadier CPU, s ktor\u00fdmi sa pri \u0161k\u00e1lovan\u00ed \u00faloh vyskytuj\u00fa probl\u00e9my. <\/p>\n

Na riadenie v Parker je implementovan\u00e9 rozhranie na b\u00e1ze kernfs a na na\u010d\u00edtanie \u010fal\u0161\u00edch in\u0161tanci\u00ed jadra do vyhraden\u00fdch oblast\u00ed pam\u00e4te sa pou\u017e\u00edva kexec. Pred spusten\u00edm \u010fal\u0161\u00edch jadier prim\u00e1rne jadro uvo\u013en\u00ed jadr\u00e1 CPU, rezervuje fyzick\u00fa pam\u00e4\u0165 a odpoj\u00ed PCI zariadenia na ich vyu\u017eitie v sekcionovanom jadre. Pre vstup\/v\u00fdstup by malo by\u0165 ka\u017ed\u00e9mu jadr\u00e1m priraden\u00e9 vlastn\u00e9 zariadenie PCIe, ako je NVMe disk alebo sie\u0165ov\u00fd adapt\u00e9r. Po spusten\u00ed in\u0161tancie jadra nem\u00f4\u017ee komunikova\u0165 s in\u00fdmi jadrami.
