[PATCH v2 0/9] Remove 32bit support on system/user emulations

Posted by Peter Xu 1 month, 1 week ago

v1: https://lore.kernel.org/r/20260814134035.2733355-1-peterx@redhat.com

In v2, I touched up the original patch per suggested.  Then I added some
more patches, almost quickly looking at references of HOST_LONG_BITS and
clean up those I feel confident about over 32bits.  I still left some there
(dev-properties, qht, etc.) which smells like tools may still use them.

Please have a look, thanks.

Peter Xu (9):
  system: Define ram_addr_t to be always uint64_t
  hw/vexpress.c: Remove forced cast to u64
  arm/mps: Remove 32bit define for MPS3_DDR_SIZE
  xen-mapcache: Remove 32bit support
  bsd-user: Remove 32bit host support in thunk_convert|print()
  linux-user: Remove 32bit host support in thunk_convert|print()
  arm/aspeed: Drop ASPEED_RAM_SIZE
  hw/arm/raspi4b: Drop board_rev for 32bit hosts
  machine: Remove 32bit limitation on ram size
