NetBSD 7.0-RC3 rilasciato: supporto SMP per RaspBerry Pi 2 e bug-fixes vari

NetBSD, così come altre distro BSD, non è un sistema che riceve aggiornamenti tutti i giorni o a giorni alterni. In questo caso, è stato rilasciato un aggiornamento enorme per NetBSD 7.0, la RC3 (Release Candidate), che porta con se molti bug-fixes e molto altro.

Una delle più importanti implementazioni di questa versione risiede nel supporto SMP per il RaspBeryy Pi 2, un’opzione disabilitata di default per lasciare che il sistema ridimensioni il file system di ROOT gestendone anche la priorità di lettura/scrittura. Troviamo anche miglioramenti nella stabilità DRM/KMS e tutti i bug-fixes elencati quì di seguito.

Bug sistemati

Ecco la lista pressoché completa:

• Add a resize_root boot operation (disabled by default). If resize_root=YES in rc.conf then the system attempts to resize the root file system to fill its partition prior to mounting read-write.
• Enable SMP on Raspberry Pi 2.
• evbarm: Rename beagleboard.img to armv7.img. The new image includes the same kernels as beagleboard.img plus support for Raspberry Pi 2, ODROID-C1, Cubieboard2, Cubietruck, Hummingbird A31, and Banana Pi.
• evbarm: For armv7.img and rpi.img, enable support for auto-growing the SD card root filesystem.
• Various DRMKMS stability improvements.
• Avoid kernel panic on starting X on Intel 855GM machines. PR kern/49875.
