GeekFest 2023 kernel

Kismet

• New features:
  • Support 2 new architectures: aarch64 and x86_64
    • 64-bit only, 32-bit apps will not run
• Enhancements:
  • Significantly improve the performance of virtualQueryEx()
  • Increase SMO/resource/stack VAS area - 64-bit only
• Bug Fixes:
  • Fix LLKMI.
  • Change lock level needed for process and SMO names to level 2 - reduce longest level 3 lock time
• Non-backward compatible changes:
  • Remove support for PE images (impacts Honeywell only)
  • Change ELF symbol resolution to match the spec
  • Remove support for the following functions:
    • setKernelAttributes - Use Ex
    • getProcessDebugStatus - Use Ex
    • physicalInterruptNumber - Use platformInterruptNumber
    • getRegistryIPCInfoBlock - No alternate, no more produce library support
    • getProducerAndConsumerIndicesFromRegistry - No alternate, no more produce library support
    • virtualReserve - Use setNextLibraryStartAddress or adjustNextLibraryStartAddress
    • mapViewOfKernelFile - Use mapViewOfKernelFileByHandle
    • firstKernelFile - Use findKernelFile or firstDirectoryEntry
    • kernelFileByHandle - Use kernelFileStat
    • nextKernelFile - Use nextDirectoryEntry
    • findFirstKernelFile - Use findKernelFile firstDirectoryEntry
    • findFirstKernelFileByHandle - Use kernelFileStat
    • findNextKernelFile - Use nextDirectoryEntry
    • platformResourcePhysicalAddress - Use platformResourcePhysicalAddress64
    • readPlatformResource[Byte|Word|DWord] - Use readPlatformResource[8|16|32]
    • writePlatformResource[Byte|Word|DWord] - Use writePlatformResource[8|16|32]
    • getSystemRequiredPadPerTick - Use getSchedulerInfo
    • setSystemRequiredPadPerTick - Use setSchedulerRequiredPadPerTick
    • getSystemRequiredPadLowWaterMark - Use getSchedulerInfo
    • setSystemRequiredPadLowWaterMark - Use setSchedulerRequiredPadLowWaterMark
  • Remove align{1,2,4,8}.h, unalign.h, pack.h, unpack.h, parapi.h, and deprecated-types.h
• Requested new features:
  • Replace names as access control with UGO - probably not backward compatible
  • Support COPY relocations
  • Consistent 653 runtime, RTEMS runtime, and RMA scheduling primitives
  • System scope semaphore
  • Shutdown hook capability
  • Create tool for platform integrator to remove need for DDCI to perform btree analysis
  • Fix, replace, or remove required pad pool
  • Support configuring pages with no execute access (for security).
  • PAL/PRL registry platform resource lookup
  • PRL interrupt handling
  • User programmable timer
  • Add Alignment requirement on BIF file integrity key'
  • callPlatformResource more data
  • exceptionHandler access to all registers (core file help)
  • ? slack pools/distribution, sleep API
  • ?

Status

• aarch64 running on qemu, not tested on real hardware.
• x86_64 in work.
• Requirements in work, aarch64 nearly complete(cpu regs).
• See Kernel_64 and Deos_64-bit_Port

Post Kismet

• Improve crittime customer guidance
• Drop 32-bit support
• Support for another processor architecture? RISC-V?
• ?
