Coreboot 4.12 yatulutsidwa

Lofalitsidwa kutulutsidwa kwa polojekiti Zovuta: CoreBoot 4.12, yomwe ikupanga njira ina yaulere ya firmware yaumwini ndi BIOS. 190 Madivelopa nawo kulenga Baibulo latsopano, amene anakonza 2692 kusintha.

waukulu zatsopano:

• Thandizo lowonjezera la ma boardboard 49, ambiri omwe amagwiritsidwa ntchito pazida zomwe zili ndi Chrome OS. Thandizo lachotsedwa pamaboardboard 51. Kuchotsako kumakhudza makamaka kutha kwa matabwa a cholowa ndikugwira ntchito yochotsa zobwerezedwa zamitundu yofananira. Mapulani ambiri omwe adawonetsedwa kale ngati zitsanzo zosiyana amaphatikizidwa mu seti (zosiyanasiyana), momwe gawo limodzi limakwirira banja lonse la zida nthawi imodzi. Poganizira zoyeretsa zobwerezabwereza, ngakhale kuti chiwerengero cha matabwa ochotsedwa chimaposa chiwerengero cha owonjezera, mndandanda wa zida zothandizira zawonjezeka. Kutulutsidwa kwatsopano kumaphatikizaponso kusintha kwakukulu kothandizira kuthandizira kwa zipangizo zomwe zimatumizidwa ndi firmware ya OEM, kuphatikizapo zomwe zimachokera ku Coreboot.
• Kuyeretsa maziko a code kunapitilira. Zolemba zazitali zamalayisensi pamitu yamafayilo zasinthidwa ndi zozindikiritsa zazifupi Zamgululi. Mayina a olemba onse omwe adatenga nawo gawo pachitukuko amasonkhanitsidwa mufayilo ya AUTHORS. Kuwunikiridwa kwa mafayilo amutu kunachitika kuti achepetse kachidindo komwe kakambidwa posonkhanitsa gawo lililonse la msonkhano.
• Ma driver a flash drive Zithunzi za SMMSTORE zozindikirika ngati zokonzeka kugwiritsidwa ntchito mofala. Dalaivala amagwiritsa ntchito SMM (mawonekedwe a kasamalidwe kachitidwe) kuti alembe, kuwerenga ndi kumasulira malo pa flash memory, ndipo angagwiritsidwe ntchito mu OS kapena zigawo za firmware kuti asungidwe kwamuyaya, popanda kufunikira kukhazikitsa dalaivala wapapulatifomu.
• Zida zoyesera ma unit zidakulitsidwa, kuphatikizidwa ndi dongosolo latsopano lomanga ndikusamutsidwa kukugwiritsa ntchito chimango cha Cmocka. Mayesero / chikwatu chosiyana chapangidwa mumtengo woyambira kuyesa mayunitsi.
• Zida zomwe tsopano ndizofunikira pamakina a x86 ndi monga RELOCATABLE_RAMSTAGE, POSTCAR_STAGE, ndi C_ENVIRONMENT_BOOTBLOCK. RELOCATABLE_RAMSTAGE imalola kusamuka kwakanthawi ramstage kudera lina lokumbukira lomwe silimalumikizana ndi kukumbukira kwa OS kapena zowongolera zolipira (kusuntha ndikofunikira chifukwa ramstage imasungidwa mu CBMEM kuti ikweze mwachangu mukatuluka mumayendedwe oyimilira). POSTCAR_STAGE imagwiritsidwa ntchito pochoka ku CAR (Cache-As-Ram) kupita ku khodi yochokera ku DRAM. C_ENVIRONMENT_BOOTBLOCK imakulolani kugwiritsa ntchito bootblock yopangidwa ndi GCC wamba, m'malo mophatikiza makina apadera a romcc.
• Khodi yothandizira mapulatifomu a AMDFAM10, VIA VX900 ndi FSP1.0 (BROADWELL_DE, FSP_BAYTRAIL, RANGELEY), omwe sakukwaniritsa zofunikira zatsopano, adachotsedwa pamakina akuluakulu. Mwachitsanzo, sizingatheke kukhazikitsa gawo la POSTCAR mu FSP1.0.
