Author: dv
Date: 2026/01/14 22:42:34

  Emulate AMD SysCfg MSR in vmm(4).

  Linux kernels like to poke this to check for memory encryption
  settings. Return 0's on reads instead of injecting #GP. Writes
  continue to be ignored.

  This reduces some noise for Linux guests on boot.

  Increase MAXCPUs on amd64 to 255

  Now that we have larger bitmask support for more than 64 CPUs, we can increase
  the max to 255. 255 is the max that xapic can support; this number can be
  bumped later if we want to discriminate x2apic vs xapic.

  Support more than 64 bits for amd64 TLB shootdown IPI masks

  The TLB shootdown code used a uint64_t to track which CPUs needed to have
  their TLB remotely flushed during pmap operations. This allowed for up to
  64 CPUs maximum on amd64.

  This diff changes the single uint64_t mask to an array of uint8_t masks,
  sized based on MAXCPUS, and utilizes the bitmask macros in param.h to
  manipulate these masks.

commit YhPQGvqlPs30eObb
Author: deraadt
Date: 2026/01/14 20:43:56

  pmap functions send various TLB shootdown operations by IPI to other cpus.
  A lock is grabbed to serialize this. Then recipient cpus get sent an IPI
  demanding this work.  The lock is reused as a counter of cpus doing the work,
  and each cpu's IPI handler decrements the counter.
  The local cpu can do some operations in the parallel, before verifying
  the TLB operations have completed in pmap_tlb_shootwait() which spins
  for the counter to reach 0.  But the counter is also a lock, and 0
  means other cpu can grab it.  So if the latency for the local work
  exceeds the latency on the recepient cpus, the "counter-lock" can be
  grabbed by a different cpu for its own TLB shootdown operations.  The
  original cpu will now spin waiting for this second cpu's work to
  finish, creating pmap function latency.
  To fix this, I create per-cpu counters which are seperate from the lock.
  The IPI functions written in asm now decrement this per-cpu counter, and
  when it reaches 0, the shared lock is cleared allowing another cpu to
  being shootdowns tracked by its own per-cpu counter.  The waiting
  function only spins on the correct per-cpu counter.
  As a bonus, the lock (and new variable indicating the shooting cpu)
  are now in cache-aligned.

  stack.c: avoid arithmetic on pointers to void

  In stack.c r1.34 I converted one 'char *' too many to 'void *', thereby
  relying on a gcc/clang extension which interprets the fictional void
  type as a type of size 1 (that's what the stack code wants, fortunately).
  As pointed out in the link below, -Wpointer-arith would have caught this:
  https://gcc.gnu.org/onlinedocs/gcc/Pointer-Arith.html

  MSVC flags this as follows:

  D:\^G\\portable\\portablerypto\\stack\\stack.c(211,23): error C2036: 'const void *': unknown size [D:\^G\\portable\\portable\^Huildryptorypto_obj.vcxproj].  
  Pull in workaround from the portable repo which undoes the char * -> void *
  conversion.

  Simplify vmd(8) structs, removing embedded vmm(4) structs.

  This removes some hard dependencies from vmctl(8) on the structures
  from vmm(4) and makes naming of identifiers more explicit.

  Oh the surface, this is cosmetic, but the intention is to decouple
  as much as possible from the dev/vmm/vmm.h to allow for upcoming
  work to change vmm(4) without causing a large blast radius.

  Testing help from mlarkin@ & bluhm@.

Author: jmatthew
Date: 2026/01/14 01:07:57

  Use scsi_io_get rather than nvme_ccb_get for passthrough commands, so we'll
  sleep if there are no ccbs available, avoiding a panic that mlarkin@ ran into.
  While here, take the rwlock around passthrough commands that come in through
  the scsi ioctl path for consistency with the bioctl path.
