seL4 Version 9.0.1 Release

Announcing the release of seL4 9.0.1 with the following changes:

9.0.1 2018-04-18: BINARY COMPATIBLE


  • On 64-bit architectures, the label field of seL4_MessageInfo is now 52 bits wide. User-level programs which use any of the following functions may break, if the program relies on these functions to mask the label field to the previous width of 20 bits. For more detail, see our explanation on the seL4 mailing list.
    • seL4_MessageInfo_new
    • seL4_MessageInfo_get_label
    • seL4_MessageInfo_set_label
  • Initial prototype RISC-V architecture port. This port currently only supports running in 64-bit mode without FPU or or multicore support on the Spike simulation platform. There is no verification for this platform.
