  • pm2fb
    driver for Permedia 2 and 2V graphics controllers It was written specifically for the Sun PGX32 card on sparc and sparc64 it hasn t been tested on any other hardware as far as I know It does support basic acceleration scrolling and rectangle fills but characters are still drawn by software and there is no support for setting video modes the driver depends on device properties to tell it what

    unaccelerated framebuffer console in 8 bit colour It s been tested on sparc64 only with XVR 500 and XVR 1200 boards Others like the XVR 600 may or may not work Currently it is not possible to run X mostly because of the insane state we get the hardware in there are two buffers and WID plane the WID plane contains garbage so it s unpredictable which pixel is drawn

  • A Keylock Security Model for kauth(9)
    come with a set of keys that are different in so far as not all positions can be reached with all keys which key can go up to which position is called the locking program With the new keylock support such locks can be used to tinker with the kernel security much like the traditional securelevel variable The number of keylock positions the current keylock position and the overall keylock state can be read within the kernel using a set of functions defined in keylock h and userland can access them through the hw keylock sysctl hierarchy The following components have been added gpiolock 4 a driver for GPIO attached keylocks The driver registers with the in kernel keylock subsystem See gpiolock c secmodel keylock a kauth 9 security model that authorizes based on the keylock closedness Wheter the rightmost default or leftmost position of the keylock means open can be controlled using the hw keylock order sysctl variable This variable can only be changed if the keylock state is OPEN See secmodel keylock c The security model is started when a keylock driver registers and stopped when there is no more keylock driver The keylock security model is optional keylock support can be used without the security model as well e g to provide keylock state to a userland applications Useful e g for POS applications The keylock state interpretation is done in keylock c and not in the driver itself This allows for adding support for multiple keylocks in the future The hw keylock pos and hw keylock npos sysctl variable have debugging character the hw keylock state variable reflects the state and should be used Currently the keylock positions are interpreted as follows There are maximum four positions OPEN SEMIOPEN SEMICLOSE CLOSE What exactly that means leaves
