Progress (short week, three days): * UM-2 [QEMU upstream maintainership] - spent pretty much all week working through the code review backlog that had built up while I was on holiday and at Connect: + RTH's patchset making various updates to the risu random-instruction-sequence tester + a patchset fixing some bugs in our GICv2 emulation + patches adding the cache controller and SMP support to xilinx-zynq + patchset modelling the STM32L4x5 USART interrupt lines properly + Alex's patches to the semihosting tests for SYS_GET_CMDLINE + a patch to fix an assert in the hcd-ohci USB controller if the guest does something silly + reviewed the first half of RTH's 60-patch patchset converting the A64 SIMD decode to decodetree (second half for next week...)
