\u00cen versiunea Fedora 42, programat\u0103 pentru sf\u00e2r\u0219itul lunii aprilie, se propune permiterea dezvoltatorilor s\u0103 includ\u0103 \u00een pachete op\u021biuni suplimentare de fi\u0219iere executabile, compilate cu optimiz\u0103ri pentru microarhitecturile x86-64-v2, x86-64-v3 \u0219i x86-64-v4. Se observ\u0103 c\u0103 Fedora continu\u0103 s\u0103 compileze pachete pentru arhitectura x86-64-v1, \u00een timp ce CentOS utilizeaz\u0103 arhitectura x86-64-v2 la compilare, iar RHEL 10 - x86-64-v3. \u00cen cele mai multe cazuri, cre\u0219terea performan\u021bei prin compilarea pentru aceste arhitecturi nu dep\u0103\u0219e\u0219te 10%, dar \u00een situa\u021bii speciale duce la o cre\u0219tere semnificativ\u0103 a performan\u021bei (p\u00e2n\u0103 la 120%). Propunerea nu a fost \u00eenc\u0103 aprobat\u0103 de comitetul FESCo (Fedora Engineering Steering Committee), responsabil pentru partea tehnic\u0103 a dezvolt\u0103rii distribu\u021biei Fedora. <\/p>\n
\u00cen Fedora este deja permis\u0103 livrarea de biblioteci suplimentare, optimizate pentru versiunile extinse ale arhitecturii x86_64, iar aceast\u0103 posibilitate se planific\u0103 acum s\u0103 fie extins\u0103 la fi\u0219ierele executabile. \u00cenc\u0103rcarea implement\u0103rilor optimizate ale bibliotecilor se realizeaz\u0103 prin linker-ul dinamic, care verific\u0103 existen\u021ba op\u021biunilor suplimentare \u00een subdirectoarele glibc-hwcaps, plasate \u00een zonele FS, care sunt c\u0103utate la accesarea bibliotecilor (de exemplu, \/usr\/lib64\/glibc-hwcaps\/x86-64-v2). <\/p>\n
\u00cen cazul fi\u0219ierelor executabile, se propune utilizarea stratului hwcaps-loader, care va selecta \u0219i va lansa op\u021biunea fi\u0219ierului executabil corespunz\u0103toare capacit\u0103\u021bilor actualei sisteme. Pentru pachetele care livr\u0103 mai multe op\u021biuni de fi\u0219iere executabile, acest strat se va propune s\u0103 fie accesibil printr-un link simbolic. Decizia de a ad\u0103uga fi\u0219iere executabile suplimentar optimizate va fi luat\u0103 de c\u0103tre \u00eentre\u021bin\u0103tori, \u00een func\u021bie de rezultatele test\u0103rii performan\u021bei pachetelor specifice. <\/p>\n
Versiunile x86-64-v* definesc o metod\u0103 neoficial\u0103 de identificare a st\u0103rilor microarhitecturii, acoperind anumite seturi de extensii: <\/p>\n
\u00cen plus, se poate men\u021biona propunerea de unificare a actualiz\u0103rilor bootloaderelor grub \u0219i shim \u00een variantele atomice \u0219i obi\u0219nuite ale Fedora. \u00cen loc s\u0103 actualizeze con\u021binutul directoarelor \/boot \u0219i \/boot\/efi printr-o apelare a scriptului \u00een timpul instal\u0103rii pachetului rpm, se propune utilizarea instrumentului bootupd pentru actualizarea bootloaderului, care este deja utilizat \u00een variantele Fedora actualizate atomic. \u00cen pachetele rpm cu bootloade, con\u021binutul ar trebui instalat nu direct \u00een directoarele \/boot \u0219i \/boot\/efi, ci \u00eentr-un director separat din interiorul parti\u021biei \/usr, dup\u0103 care s\u0103 se sincronizeze con\u021binutul cu \/boot \u0219i \/boot\/efi. Aceast\u0103 abordare va permite realizarea unei op\u021biuni de rezerv\u0103 pentru bootare, care poate fi utilizat\u0103 pentru a reveni la o configura\u021bie anterioar\u0103 \u00een cazul unor probleme dup\u0103 actualizarea bootloaderului. \u0412 \u0432\u044b\u043f\u0443\u0441\u043a\u0435 Fedora 42, \u043d\u0430\u043c\u0435\u0447\u0435\u043d\u043d\u044b\u0439 \u043d\u0430
