Kdump will come later (requires updates to libfdt). # # - Optimisation of our dynamic CPU feature framework, so that all # detected features are enabled via a single stop_machine() # invocation # # - KPTI whitelisting of Cortex-A CPUs unaffected by Meltdown, so that # they can benefit from global TLB entries when KASLR is not in use # # - 52-bit virtual addressing for userspace (kernel remains 48-bit) # # - Patch in LSE atomics for per-cpu atomic operations # # - Custom preempt.h implementation to avoid unconditional calls to # preempt_schedule() from preempt_enable() # # - Support for the new 'SB' Speculation Barrier instruction # # - Vectorised implementation of XOR checksumming and CRC32 # optimisations # # - Workaround for Cortex-A76 erratum #1165522 # # - Improved compatibility with Clang/LLD # # - Support for TX2 system PMUS for profiling the L3 cache and DMC # # - Reflect read-only permissions in the linear map by default # # - Ensure MMIO reads are ordered with subsequent calls to Xdelay() # # - Initial support for memory hotplug # # - Tweak the threshold when we invalidate the TLB by-ASID, so that # mremap() performance is improved for ranges spanning multiple PMDs. # # -
