[ACTIVITY] report week ending 28 Sep

2018-09-28 Thread Peter Maydell 
Progress:
 * Post-travel/holiday catchup (email, expenses claims, code review,
   team meetings etc)
   (this was the lion's share of the time)
 * VIRT-65 [QEMU upstream maintainership]
   - some patches to fix clang warnings about taking the
 address of a field in a packed struct
   - make the compatibility "virt-2.10" machine really behave like the 2.10
 QEMU's virt board: don't generate external aborts for accesses to bad
 physical addresses. (It turns out a few misconfigured Linux
kernels do this.)
   - noticed that we only have another 40 or so devices to convert
 to be able to complete an API transition (sysbus init methods):
 wrote this up for the list to nudge people into doing some conversions

thanks

SVE Support ([VIRT-198])


  - generated a [narrow test case for fdiv_64 rounding error]
- doesn't hit much code but I possibly misunderstanding [the code]
  AFAICT inc = ((frac & roundeven_mask) != frac_lsbm1 ? frac_lsbm1 :
  0); seems reasonable

QEMU plugin support ([VIRT-280])

  to cleanly add memory tracing
