Xen 4.16 inosvika nerutsigiro rwekuvandudzwa kweARM, chiteshi chekutanga cheRISC-V nezvimwe.

Mushure memwedzi misere yebudiriro, yemahara Xen 4.16 hypervisor yakaburitswa, vhezheni umo makambani akadai seAmazon, Arm, Bitdefender, Citrix uye EPAM Systems akabatsira mukuvandudzwa kweiyo vhezheni.

Kune avo vasina kujaira Xen, iwe unofanirwa kuziva izvo yakavhurwa sosi chaiyo muchina wekutarisa yakagadzirwa neYunivhesiti yeCambridge. Dhizaini yekugadzira ndeyekukwanisa kumhanyisa zviitiko zvinoshanda zvehurongwa nenzira inoshanda zvizere pane imwechete komputa.

xen inopa yakazvimiririra yekuzvimiririra, kudzora zviwanikwa, mhando yevhisi yebasa uye inopisa inopisa muchina kutama. Masisitimu anoshanda anogona kushandurwa zvakajeka kuti amhanye Xen (uku uchichengetedza kuenderana nemashandisirwo emushandisi).

Izvi zvinogonesa Xen kuzadzikisa kuita kwepamusoro-kuita. pasina yakakosha Hardware rutsigiro. Intel yaita mipiro yakati wandei kuXen iyo yawedzera rutsigiro kune yayo VT-X Vanderpool ekuwedzera ekuwedzera.

Iyi tekinoroji inobvumidza isina kugadziridzwa masisitimu anoshanda kuti aite seanogadzira mukati memachina chaiwo Xen, chero bedzi sevha yepanyama inotsigira iyo Intel VT kana AMD Pacifica yekuwedzera.

Muiyi vhezheni nyowani ye hypervisor inoratidzwa kuti in TPMManager, iyo inopa chaiwo machipisi ekuchengeta cryptographic makiyi (vTPM), anoitwa pahwaro hweyakajairika TPM yemuviri (Trusted Platform Module), Yakagadzirwa kuti iwedzere kutsigira iyo TPM 2.0 yakatarwa.

Uyewo se yakawedzera kuvimba kukuru paPV Shim layer inoshandiswa kumhanyisa isina kumodified paravirtualized guest (PV) masisitimu muPVH neHVM nharaunda. Mune ramangwana, kushandiswa kwe32-bit paravirtualized vaenzi masisitimu kunogoneka chete muPV Shim modhi., iyo inoderedza huwandu hwenzvimbo mu hypervisor uko kunogona kuve nekusagadzikana.

Izvo zvakare zvakasimbiswa izvo zvidimbu zvisakara zvakacheneswa, yakamira kuunganidza "qemu-xen-traditional" uye PV-Grub kodhi nekukasira (kudiwa kwemaforogo eXen-chaicho kwakanyangarika mushure mekuchinja kweXen-kunoenderana kwakatakurwa kuenda kuQEMU neGrub huru).

Kune rumwe rutivi, tinogona kuwana iyo yakagadziridzwa rutsigiro kune isiri-dom0 modhi, izvo zvinokutendera kuti upfuure kuitwa kweiyo dom0 nharaunda nekutanga chaiwo mashini panguva yekutanga server yekutanga. Shanduko dzakaitwa dzinobvumira kuitwa kwerutsigiro rwe64-bit ARM masisitimu ane EFI firmware.

The rutsigiro rweARM masisitimu 64-bit heterogeneous systems based on the big.LITTLE architecture, kubatanidza macores ane simba, asi anopedza simba uye asinganyanyi kushanda zvakanaka, asi mamwe macores anoshandisa simba pane imwe chip.

Kunze kwezvo, futi chiteshi cheRISC-V chinomira pachena, iyo panguva iyi yekuburitsa, basa rakakosha rakaitwa mukati kuti dom0 itange paRISC-V Hardware, ichitarisa kuunza mashandiro ekubvumidza kukanganisa manejimendi, pamwe nemamwe mainterface anodiwa kune yekutanga boot kodhi.

Yeimwe shanduko izvo zvinoratidzika kubva pane iyi nyowani vhezheni:

  • Yakawedzera kugona kubhutsu paIntel zvishandiso pasina Programmable Interval Timer (PIT).
  • Kune vashanyi veARM, rutsigiro rwekutanga rwe virtualized performance monitor counters rwakaitwa.
  • Kuwedzera kutsigirwa kwehardware nekubvumira Xen kuti itange paIntel zvishandiso zvisina programmable interval timer.
  • Kucheneswa kwezvinhu zvenhaka paunomira kuunganidza QEMU Yechinyakare kana PV-Grub nekusarudzika. Ziva kuti mapurojekiti ese ari maviri akabatanidza Xen kumusoro kwerutsigiro izvozvi, saka kushandisa Xen-chaiwo maforogo hazvichakurudzirwe.
  • Yekutanga rutsigiro rwemuenzi virtualized performance monitor counters paArm.
  • Rutsigiro rwakavandudzwa rweanosiyana 64-bit Arm masisitimu nekudzikamisa mabasa eCPU kune ese kuti avandudze tsigiro huru.LITTLE.

Finalmente Kana iwe uchida kuziva zvakawanda nezvazvo, unogona kubvunza ruzivo mune inotevera chinongedzo. Kuburitswa kwekuvandudzwa kwebazi reXen 4.16 kuchagara kusvika Chikumi 2, 2023 uye kuburitswa kwezvigadziriso zvekusagadzikana kusvika Zvita 2, 2024.


Izvo zviri muchinyorwa zvinoomerera pamisimboti yedu ye tsika dzekunyora. Kuti utaure chikanganiso tinya pano.
