\u00c8 stato pubblicato il primo rilascio sperimentale del progetto Neptune OS, che sviluppa un'interfaccia sopra il microkernel seL4 con l'implementazione di componenti del kernel di Windows NT, mirata a fornire supporto per l'esecuzione di applicazioni Windows. Il codice \u00e8 distribuito sotto licenza GPLv3. <\/p>\n

Il progetto implementa il \"NT Executive\", uno dei livelli del kernel di Windows NT (NTOSKRNL.EXE), responsabile della fornitura di API per le chiamate di sistema NT Native e un'interfaccia per il funzionamento dei driver. In Neptune OS, il componente NT Executive e tutti i driver vengono eseguiti non a livello kernel, ma in forma di processi utente in un ambiente basato su microkernel seL4. L'interazione del componente NT Executive con i driver avviene tramite l'IPC seL4 integrato. Le chiamate di sistema fornite consentono di garantire il funzionamento della libreria NTDLL.DLL con l'implementazione dell'interfaccia software Win32, utilizzata nelle applicazioni. <\/p>\n

La prima versione di Neptune OS include il driver della tastiera (kbdclass.sys), il driver della porta PS\/2 (i8042prt.sys), il driver per il segnale acustico (beep.sys) e l'interprete della riga di comando (ntcmd.exe), trasferiti da ReactOS e in grado di dimostrare i principi di base dell'organizzazione del lavoro. La dimensione dell'immagine di avvio \u00e8 di 1.4 MB. <\/p>\n

L'obiettivo finale \u00e8 portare il livello a uno stato sufficiente per il porting dell'ambiente utente e dei driver di ReactOS. Gli sviluppatori stanno anche esplorando la possibilit\u00e0 di raggiungere la compatibilit\u00e0 binaria con i file eseguibili di Windows e una compatibilit\u00e0 accettabile a livello di codice sorgente con i driver del kernel di Windows. <\/p>\n

Il principale ostacolo nel garantire il supporto per i driver di Windows \u00e8 l'uso, nella maggior parte dei driver del kernel di Windows, di un protocollo di comunicazione non standard quando interagiscono con altri driver, richiedendo il passaggio diretto di puntatori, cosa che non pu\u00f2 essere realizzata in Neptune OS a causa dell'esecuzione dei driver in processi separati.
